The war drums were beating rhythmically. The shrimp car, which could only be pushed by thirty people, was slowly approaching the moat of Lengquan Pass under the hard push of the Sui soldiers. The wall was riddled with holes by artillery. Arrows fell like rain, constantly nailing the shields of the toad carts and the shields held high in the left hands of the Sui army soldiers. During this period, one Sui army soldier was hit by arrows, and screams of pain and groans were heard one after another. The Sui army soldiers were slightly injured. After gritting his teeth and being seriously injured and killed, the Sui soldier fell down. Immediately, his companions holding shields rushed up to take his place. Together with other cart companions, they struggled to push the toad cart loaded with earth and rocks, slowly but firmly. Move forward slowly. On the edge of the moat, after the Sui army officers and soldiers built six temporary fortifications with long shields, the Sui army archers were also struggling to pull their strong bows, throwing blind fire at the wall, trying their best to suppress the garrison and prepare for the attack. The Toad team shares the pressure. Arrows flew like locusts in the sky, and occasionally some large rocks thrown by the remaining trebuchets of the Lengquan Pass defenders fell down. The dead bodies of Sui army officers and soldiers were scattered on the ground, with broken arrows and broken feathers as dense as poles of grass. The vibration of bowstrings mixed with the sound of shouts and chants. One stream, soaring straight into the sky. The soldiers of the Sui Army fought very hard, but compared to the pressure that other armies suffered in the attack, the soldiers of the Sui Army could definitely be considered extremely lucky, because the artillery of the Sui Army had completely destroyed the tower of Lengquan Pass. The archery tower completely cleared the defenders' bed crossbows on the pass wall, and even bombarded the defenders' fortifications on the highlands on both sides of Lengquan Pass to pieces, destroying at least 60% of the defensive power of the Lengquan Pass defenders, causing a three-dimensional collapse of the Lengquan Pass defenders. The strike power was seriously insufficient, and the threat to the Sui army officers and soldiers was greatly reduced. Otherwise, the Sui army's battle would be several times or even ten times more difficult to fight. The toad cart of the Sui Army was only fifty steps away from the city moat. There was a bang on the wall, and an archer from the Taiyuan Army was suddenly lowered on a rope from the wall. He quickly hid behind the wall of sheep and horses that could avoid arrows, and then They drew their bows and released arrows, and fired at the Sui army officers and soldiers behind the chariots. However, the Sui army's chariots were well prepared, and they had long shields in hand to protect the two wings, blocking most of the cross-fired arrows. At the same time, the remaining dozen or so trebuchets in Lengquan Pass also tried their best to throw stones, covering the Sui army's toad convoy as much as possible. A big stone hit the head of the Sui Army's toad convoy. A poor Sui Army soldier was smashed into pieces. Before he could even scream, he was smashed to pieces with his shield and his men. However, before the defenders of the Pass could cheer, the Sui army's artillery more than a mile away suddenly fired again, throwing heavier and more powerful shells into Lengquan Pass. The sound of cracking wood and the screams of soldiers immediately came from the Pass. While we were going back and forth with each other, the Sui army's toad truck finally arrived at the edge of the moat. The Sui army soldiers pulled up the baffle and struggled to lift the car body. The heavy earth and stone slid into the trench by gravity, and it was filled up in the blink of an eye. After entering a trench, the Sui Army soldiers immediately cheered the trailer and fled back, quickly withdrawing from the range of the bows and arrows of the Lengquan Pass defenders. At the same time, the second toad truck loaded with heavy earth and rocks also arrived at the Sui Army soldiers. The push direction was already slowly moving towards Lengquan Pass, and the artillery of the Sui Army also immediately adjusted its target, seizing the opportunity to find every opportunity to bombard the Taiyuan Army archers hiding behind the sheep and horse wall with all their strength. Li Jing used the most formal and slow siege tactics, but the slower and more formal the siege tactics were, the less likely the Lengquan Pass defenders were to find a way to restrain and crack down, because this kind of formal siege tactics was used by armies of all ethnic groups in the Central Plains. The crystallization of wisdom gained from countless actual battles, it is slow and correct, never opportunistic, and does not give the enemy any chance to opportunistically. Therefore, even though the garrison of Cold Spring Pass jumped in haste and tried their best to prevent the destruction, they still could not stop it. The Sui army's toad trucks gradually filled up the trenches they had worked so hard to dig, and gradually opened and widened the road for the Sui army's soldiers to reach Guanxia. Although the Sui army showed no signs of launching an ant attack on the city, just seeing the gradually filled-up trenches, an atmosphere of despair had already enveloped the heads of the Lengquan Pass defenders, because the Lengquan Pass defenders were exhausted from top to bottom. It is clear that the enemy does this not because they are afraid of the ants attacking the city, but to sharpen their swords and cut firewood. When the enemy's main force actually launches the ant attack, it will definitely be thunderous and overwhelming, overwhelming! The morale that had already been severely damaged by the Sui army's artillery dropped even further. Many Taiyuan army officers and soldiers were already secretly thinking about how to avoid the sharp ax of the supervising team and surrender to the enemy on the opposite side when Lengquan Pass could no longer be defended. The Sui army's trench-filling operation lasted for a full day, and they did not withdraw their troops back to camp until dusk. By the time the Sui army soldiers withdrew, more than 70% of the trenches outside Lengquan Pass had been filled in. Even without the Sui army, The Taiyuan army was unable to dig out the soil filled by the Sui army in a short period of time despite the destruction and obstruction of the army. Frustrated expressions were written on the faces of every Taiyuan Army soldier. They weakly packed up the defense equipment. What the Taiyuan Army soldiers were talking about was whether the enemy would launch an attack the next day. Some Taiyuan Army soldiers had such whimsical thoughts that they knelt down and prayed to the sky for heavy rain the next day so that the enemy would not be able to attack them the next day.??launched an ant attack, but the stars and the bright moon that gradually filled the night sky not only told him that this was just a wishful thinking, but also his experienced companions sneered: "In a battle with Chen's army, how can you expect to encounter something that is beneficial to us?" Weather? Haven't you heard that the man named Yuan Tiangang in Chen's army can control the wind and rain, and make it rain and sunny? When we were in Yanmen, our general was doing this. His big loss!" During the discussion, Li Jiancheng's messenger suddenly came to Lengquan Pass and announced to the Lengquan Pass defenders on behalf of Li Jiancheng that the Lengquan Pass defenders had done a good job guarding the pass today, so Li Jiancheng decided to reward the Lengquan Pass defenders with wine and meat, and also rewarded everyone. A piece of cloth. However, it is a pity that the reward method has little effect on the low morale of the Lengquan Pass defenders. There were very few cheers among the Lengquan Pass defenders, and many soldiers whispered: "The Governor Zuo is preparing to give us the last meal." Have we had dinner? If Chen¡¯s army launches an attack on the city tomorrow, how many of us will be able to eat tomorrow¡¯s dinner?¡± After noticing the low morale of his men, Zhang Lun took the time to return quickly. He visited the main camp of the Taiyuan Army once and reported the army situation to Li Jiancheng face to face, explaining that his army had been severely damaged by the Sui Army's artillery and morale, and had consumed a lot of physical strength in today's long-range weapon attack. If it continues like this, it may be detrimental to the battle. , begged Li Jiancheng to send another general to lead the army to take over Lengquan Pass, replacing his own troops with low morale and heavy casualties. Li Jiancheng rejected Zhang Lun's request for a defense change without hesitation and said: "Manager Zhang, I understand your difficulties, but a hasty change of defense with new troops who are not familiar with the terrain and do not understand the defense situation will only make the battle more disadvantageous. Now another war is imminent. So I can't take the risk of changing defenses. But don't worry, as long as you withstand the frontal attack of Chen's army, I will immediately change your defenses and let your army withdraw to rest day and night. What about a continuous attack?" Zhang Lun asked, and then said: "Looking at the posture of Chen's army, they will definitely launch an attack tomorrow, and it is very likely that they will attack continuously day and night. By then" "If this is the case. , then I will add a thousand troops to you tomorrow evening." Li Jiancheng interrupted Zhang Lun and said: "The day after tomorrow, I will send troops to replace your army." Li Jiancheng has already said this. Zhang Lun didn't have much to say, so he could only say goodbye respectfully and leave. As soon as Zhang Lun left, Li Jiancheng immediately asked Zhang Daoyuan next to him: "How is the food transportation team in Taiyuan? Have you contacted me yet?" "Contacted." Zhang Daoyuan replied in a low voice: "According to Governor Zuo's order, Shen Shuan has led the grain transport team to turn around and return to Taiyuan City." Li Jiancheng nodded and said nothing, but Yin Kaishan asked in a low voice. : "Captain Zuo, we only have enough grain and grass in our camp for ten days. You also ordered the grain transport team to send the grain and grass back to Taiyuan. Do you think that Lengquan Pass can't be held for ten days?" "I can hold it for five days. Thank God." Li Jiancheng sighed softly and said in a low voice: "I saw with my own eyes the power of Ying Liangxian's artillery yesterday, and I thought it was too simple before. In fact, even our water attack. If the plan is not exposed, it will definitely not last until the flood season comes. Brother Ying Liang's artillery is so powerful. From a distance of more than a mile, a cannon can smash an arrow stack into pieces, and then continue to kill and injure people. If I hadn't seen it with my own eyes, I wouldn't have believed that there was such a powerful weapon in the world. In the face of such a powerful weapon, Lengquan Xiaoguan wouldn't have been able to hold on for long. " Zhang Daoyuan nodded and asked in a low voice: "Commander Zuo, So if Lengquan Pass suddenly falls, how can we resist the enemy's pursuit? Can Fan Botong, who is guarding Jiexiu, temporarily hold back the main force of the enemy?" "Don't worry, I have made arrangements," Li Jiancheng replied calmly. He lowered his head slightly, sighed, and said: "I just hope Zhang Lun can persist for one day and one night, so that we can be a little more relaxed." As Zhang Lun expected, the Sui army came again the next morning. At the foot of Lengquan Pass, several ladder trucks and a large number of flying ladders were also brought for the construction of Lengquan Pass. At the same time, before the war started, the Sui army's artillery bombarded the city of Lengquan Pass indiscriminately. Lift it up as much as you dare. As soon as Zhang Lun saw that the Sui army was coming unfavorably, he organized his troops to defend with all their strength. At the same time, he sent a horse to warn Li Jiancheng that the Sui army was about to launch an ant attack. The answer he received was, "Hold on with all your strength!" The Sui army officially When launching the Yifu offensive, Li Jiancheng also issued a new order to the main force of the Taiyuan Army. He said that the Sui Army's attack would be continuous day and night and would last for an extremely long time. Therefore, the army was asked to make fire and cook food with all their strength to provide food for every soldier. Five days of dry food should be carried with you, and a large number of torches should be prepared so that each army and battalion can go to the battlefield at any time without worrying about running out of food or torches. As a result, this command sendsAfter arriving in front of Li Er, Li Er immediately sneered and said: "You're not stupid, I knew you were ready to run away." After finishing his sneer, Li Er did not hesitate to order his troops to follow the order, but it was a pity. , the approximately 6,000 soldiers and horses of Li Er's headquarters who went south from Taiyuan during this war, now have less than 3,000 soldiers left, and nearly half of them are wounded, and many of them are seriously ill. Although Li Er did not regret this, he could not help but secretly resent Liu Heitai for being treacherous and cunning at the expense of his own army. He also hated his brother for being ruthless and never replenishing his troops, causing his direct lineage to become less and less numerous. The more he fought, the weaker he became. However, just when Li Er was secretly resenting Li Er, Li Jiancheng, who had had a big quarrel with Li Er just the day before, sent a man and ordered Li Er to pay a visit to the Chinese army's tent. Guessing that his brother did not dare to kill him at this critical moment, Li Er confidently came to the Chinese army's tent to meet with Li Jiancheng. After meeting, the first thing Li Jiancheng did was to leave the rest of the people in the tent alone, and then he was very direct. He said to Li Er: "Second brother, if Lengquan Pass is captured by the enemy, the main force of our army will immediately retreat to Taiyuan. At that time, you will lead the headquarters to be responsible for the rear." "What? I am the rear?!" Li Er jumped three feet high. . "I will replenish you with one thousand troops." Li Jiancheng went straight to the point and said: "After withdrawing from Taiyuan, no matter how many troops you have left, I will replenish you with five thousand troops! I will give you enough weapons and equipment, and I will give you more You have six hundred war horses!" Li Er was stunned, rolled his eyes and calculated for a moment. Li Er said: "I have one more condition. When Lengquan Pass cannot be defended, you must immediately order Wenshui to dig out the dam and release it. Flood! Stop the main force of Chen Thief!" "You don't need to teach me about this." Li Jiancheng replied calmly: "To tell you the truth, I have already set up a beacon tower ten miles away in the northwest. If the Lengquan Pass cannot be sustained, I will immediately stop it. I sent a horse to order the smoke to be lit there. When I saw the smoke, my uncle would immediately dig the embankment and release the water. Also, I have already given the order to my uncle to be ready to dig the embankment at any time. "Brother, he is really hiding his secrets." Li Er smiled and said, "Okay, I'm the queen." Li Jiancheng also smiled, and then called over the five captains who had been waiting outside the tent to listen to their orders. Lead his headquarters to move to Li Er's camp and accept Li Er's orders from now on. After Li Er happily left with the five captains, Jiexiu guard Fan Botong also came to Li Jiancheng to give orders. Li Jiancheng's attitude towards Fan Botong was far more kind than his attitude towards his younger brother. He took Fan Botong's hand and talked a lot. After reflecting on his words, he shed tears and gave Fan Botong a dangerous order, requiring Fan Botong to hold on for ten days after the fall of Lengquan Pass. If he could break through after ten days, he would break out. If he couldn't break out, Fan Botong could also surrender to save his life. Li Jiancheng didn't say a word. Blame. Li Jiancheng was also very accurate in judging people. After listening to Li Jiancheng's considerate cry, Fan Botong couldn't help but shed tears. Choking with sobs, he promised Li Jiancheng to defend the city for more than ten days, and promised that if he could not break through, he would defend the city to the end. Now, if the city dies and people die, if possible, we must persist until Li Jiancheng wins the battle to defend Taiyuan and returns to rescue the small town of Jiexiu. Li Jiancheng burst into tears when he heard this, and hugged Fan Botong and cried. While crying, Li Jiancheng had been paying attention to the faint shouts of killing coming from Lengquan Pass in the south, and said in his heart: "General Zhang Lun, I am really sorry, for the safety of the main army, I have to lie to you once. Don't worry if I don't give it to you. , I don¡¯t want you to defend until tomorrow morning, as long as you defend until tonight.¡± The battle at Lengquan Pass was much harder than Li Jiancheng imagined. After the bombardment stopped at noon, the Sui army¡¯s siege of the city never stopped. Each battalion and school of the Sui army took turns to go into battle, carrying flying ladders and constantly attacking the narrow Lengquan Pass wall. The Lengquan Pass defenders, who had lost the ability to strike immediately, could not effectively suppress the Sui army's charging momentum. They could only rely on condescension. The last advantage barely withstood the Sui offensive. Every time the Sui soldiers rushed to the top of the pass wall, they usually brought several times more casualties to the defenders of Lengquan Pass. Zhang Lun led the death squads to put out fires everywhere, killing them so hard that even the blades of their knives were curled. The fierce fighting lasted until just after Shenshi in the afternoon, when the supervising team sent by Li Jiancheng executed more than half a hundred Taiyuan Army deserters on the spot. The soldiers of the Sui army who dug the city had already dug a deep pit that could accommodate people on the rammed earth pass wall. The infantry of the Sui army had also occupied the mountain high ground to the east of Lengquan Pass and began to throw rocks and arrows into the pass. However, the defenders of Lengquan Pass still remained. The reason for struggling to support the pass was not out of loyalty, but because Zhang Lun personally told Li Jiancheng, who was guarding the pass, to promise that if he persisted until dark, fresh troops would be replenished, and if he persisted until the next morning, he could change defenses and withdraw to the camp to rest. , the defenders of Lengquan Pass relied on this hope to have the will to continue to persevere, but they had no idea that their main army was already making arrangements to retreat, and it was absolutely impossible to send them reinforcements. When the sun gradually set in the west, the Sui army officers and soldiers who were attacking like a wave had successfully seized the opportunity.A Guanqiang position was established, and subsequent troops were able to continuously board the pass. Zhang Lun personally led the death squads to fight for the Guanqiang position inch by inch with the Sui army soldiers, while sending fast horses to Li Jiancheng for help. However, when the soldiers sent by Zhang Lun rushed back to the Taiyuan Army camp northeast of Jiexiu with sweat and blood on their faces, they were shocked to see that the main force of the Taiyuan Army was already heading north, and then he himself was ordered to be detained by Li Jiancheng. He was not allowed to bring the news that the main force of the Taiyuan Army had begun to retreat back to Lengquan Pass to shake the morale of the army. It was also when the sky was getting dark and all the main forces of the Taiyuan army left the camp and headed northward, Li Jiancheng sent someone to send an order to Zhang Lun, asking Zhang Lun to abandon his troops and leave Lengquan Pass immediately, and follow him north back to Taiyuan City. After receiving this order, Zhang Lun finally understood that Li Jiancheng had actually planned to abandon Cold Spring Pass. In anger, he almost wanted to lead his army to surrender to the Sui army. However, he was worried about his wife and children who were detained by the Li brothers in Taiyuan City. , Zhang Lun quietly left Lengquan Pass with tears in his eyes, leaving a group of his men to continue the bloody battle with the Sui soldiers on the wall of Lengquan Pass. When it was completely dark, Lengquan Pass without the command of the general was finally broken by the Sui soldiers. However, when the Sui soldiers placed the military flag on the wall and cheered, the Wenshui River in the northwest merged into the mouth of Fenshui River. Suddenly there was a sound like thundering water. The Wenshui torrent that had been accumulated for more than ten days rushed into the Fenshui River. It first overflowed the road that the Sui army soldiers must pass through to pursue the Taiyuan army, and then changed its course to the south and rushed into the Fenshui River. Queshu Valley flooded several sections of the low-lying Queshu Valley road one after another. Although the Sui army had already prepared to quickly retreat to the highlands, the flood was not too big and was destined not to endanger the safety of the Sui army's camps. However, it also gave the Sui army The pursuit of troops brought a huge threat. Cheng Yaojin and Qin Qiong, two cavalrymen sent by Chen Sangliang to pursue the Taiyuan army, were also blocked by sudden floods and had no choice but to temporarily halt their horses. "It will take at least one night." This is what Li Jing said helplessly to Yuan Tiangang, saying: "I underestimated Li Jiancheng, who was always known for his loyalty. I never thought that he would deliberately let the Lengquan Pass defenders die in vain to buy him time to retreat. , while retreating, we decisively released water. This time we have little hope of annihilating his main force outside Taiyuan City. " Unlike Li Jing, who was quite disappointed, Chen Sangliang did not show any concern after receiving the news from Lengquan Pass. There was no regret or disappointment at all, and he also said: "Send fast horses to convey orders to Qin Qiong and Cheng Yaojin, telling them that there is no need to try hard to outflank and cut off the Taiyuan rebel army's retreat. If the infantry can't keep up with them, no matter how roundabout they are, it will have little effect. , just let them fight the pursuit battle to make the enemy disperse as much as possible. Also, try your best to get Li Erlang's head! If they get to Taiyuan City, I will also give them a great credit!"
