With two loud noises, all the engineers who were working involuntarily stopped their work and raised their heads to follow the two fireballs. However, the position where Jiang Fu was standing was obscured by the smoke rising in front, and he could not see clearly what was below. The engineer is already being a curious baby, otherwise he would definitely be jumping around and yelling. Not only the engineers of the Han army, but also the soldiers guarding the city wall in the distance on the Tianjiaping Fortress were also following the two fireballs. Although the first one passed over the city and did not cause any damage to them, it The movement still made almost all the Qin soldiers tremble with fear. It¡¯s close, it¡¯s close! With a heartbreaking scream, the city suddenly panicked, because the two fireballs were rapidly approaching and descending, and this time, they would not miss again. There were two more loud noises, and a cannonball hit the city wall. The entire wall of Tianjiaping Fortress seemed to be shaking with the impact of the cannonball. A section of the wall was missing, and the cannonball that penetrated the city wall was almost consumed. After losing all its kinetic energy, it sprang out from the earth and stone city and whirled on the ground. The dark, round projectile was like a devil, and it stopped quietly in front of a group of Qin soldiers. They looked at the now-quiet object in front of them with horror. Just now, this guy smashed the city wall not far away from them, which they regarded as a guarantee. The other shell did not hit the city wall, but it hit the tower above the fortress. The wooden tower collapsed instantly with a crashing sound. Almost half of the building fell down, and the raging fire burned instantly. Several soldiers, covered in flames, danced and ran out of the ruins, screaming loudly as they ran, rushing towards the city wall and rushing out of the gap that had just been blasted. He fell to the bottom of the city with a clatter, and the screams stopped, but the flames continued to burn. The soldiers on the city silently stared at the flames burning below the city, and the look of horror on their faces could not be concealed no matter what. Gou Xin was also on the tower, but he was very lucky when a beam collapsed. Just hit the ground. One end was still supported on the beam, which coincidentally formed a triangular safe zone above his head. This allowed him to escape the disaster without any risk. Otherwise, Tianjiaping would have been attacked by the enemy before the official attack. When it unfolds, they will lose their top officer here. Although he luckily escaped with a life, Gou Xin's current appearance is indeed not very good-looking. There were flames burning in many places all over his body, and he seemed to have just been dug out of the earth. When the sound of fire broke out, several guards quickly picked up a basin of water from the water storage in the city and poured it on his face with a splash. The body immediately turned him into a drowned rat. ¡°Put out the fire, put out the fire immediately!¡± Gou Xin shouted loudly, regardless of his current image. On the city wall, water tanks and sand for extinguishing fires are ready. It's just that the Qin army never expected that the enemy's method of arson was not what they imagined. The soldiers rushed to put out the fire in panic, but Gou Xin quickly stepped to the edge of the city wall and looked at the Han army in the distance. Although his face was calm, he was extremely worried in his heart. What kind of weapon is this? It makes a violent explosion sound like a grenade. But grenades are thrown by people, but this thing is not. No matter how strong a person is, it is impossible to throw a grenade from outside. He touched a grenade in his arms. Now Hangu Pass's own military workshop can also make grenades. The outside is a clay pot with gunpowder inside. After lighting the fuse and throwing it out, the broken porcelain fragments produced after the explosion can cause damage to the enemy, but the one in his arms is not It was secretly smuggled from the Han Kingdom. The quantity was very small, and it was only equipped to the commander's confidant Yingbu. He only had one because his brother Gou Yi was now the leader of the Yingbu. The grenades made in the Han Kingdom are made of iron, and the iron is carved with extremely regular patterns. Gou Xin heard his brother's description that the grenades made in the Han Kingdom were several times more powerful than the homemade grenades in Hangu Pass. This situation made Gou Xin very discouraged. In the distance, two more flames flashed. Gou Xin subconsciously bent down and hid behind the wall, but then he remembered that if the previous weapon happened to hit his position, even if he was hiding behind the wall, Unable to protect himself at all, he simply straightened up. He stared intently at the two iron sparks roaring in the air. After two loud noises, two more sections were stepped on the city wall. This is simply not something that can be stopped by human power. Gou Xin turned around and ordered loudly: "Except for the soldiers operating the crossbows and trebuchets, the other soldiers immediately withdrew under the city wall and stood close to the walls. No one is allowed to come up without my order." The most instinctive reaction of a general was to issue the most correct order. The Qin soldiers who were waiting in the city descended from the city wall one after another. The artillery no longer posed much of a threat to them. Only a few hundred operators remained on the city. Soldiers with ranged weapons. Gou Xin took a few steps to a trebuchet, pointed at the two places in the distance where smoke was rising from time to time, and said loudly: "Aim at that place, hit me, and smash them." "General, We can't hit it, the distance is too far, even our trebuchet can't reach it at its farthest range!" The soldier's voice was filled with tears. Only when others hit him, he couldn't fight back. This kind of thing can't be done in any situation. People are extremely useless. The trebuchet could not be hit, and the bed crossbow was useless. At this time, Gou Xin suddenly resented the commander. In the past two years, the commander had obtained a lot from the Han Dynasty through some smuggling channels and eliminated them. The bed crossbow is one of the weapons. The bed crossbow has long been eliminated among the Han army because of its heavy weight and limited power. However, for the Qin army, the range of the bed crossbow produced in the Han country is much higher than that of the Qin army. The range of the weapon is one-third farther. If there are a few here, they might be able to pose a threat to the strange weapons of the Han army. However, the commander did not allocate one of these good things to Lubin Fortress. Gou Xin couldn¡¯t figure it out. How could he say that this was also the front line against the Han army and the most important place. If Lu Bin was lost, the Han army would be able to advance straight in and directly threaten Hangu Pass. From his brother's vague meaning, Gou Xin also knew that the commander's strategic focus was not on the Han army on the opposite side, but on Xianyang. The best armor and the best weapons were all equipped in that direction. On top of the troops, Gou Xin couldn't help but shudder when he thought of the person the commander was going to deal with. Over there was the king of Qin! But Gou Xin has no way out. As his brother said, everything about the Gou family is tied to the commander-in-chief. Everyone also regards the Gou family as the commander-in-chief's most confidant. If the commander-in-chief collapses, the Gou family will definitely survive. No, that is a serious crime that will punish the nine tribes. Now the only way to succeed is to beg the commander-in-chief. In this way, the Gou family may usher in a great wealth. Killing weapons that cannot hit the opponent from a long range, using them to deal with those engineers who are widely dispersed is completely overqualified. They can't hit, and it is a waste of weapons. Gou Xin finally stopped this useless work and watched helplessly. Watching the engineers and soldiers of the Han army under the city carry out civil engineering work slowly and slowly, clearing away the obstacles they had worked so hard to lay out bit by bit. A strange scene occurred on the Tianjiaping Fortress. Below the city, the Han army engineers slowly advanced, but there was silence on the city. Occasionally, the Han soldiers in the distance would fire a few cannons, but they would only be a dozen and a break. Jiang Fu was also very dissatisfied. He originally thought that he could use cannons to cause heavy damage to the enemy, but the guard on the city was obviously an extremely shrewd man. Before, he could still see the crowds of people on the city, but now, almost no one can be seen. Okay, obviously, the other party is hiding. "Can we destroy their trebuchets and bed crossbows?" Jiang Fu asked the gunner in front of him. The gunner commander had become a big-faced man at this time. After listening to Jiang Fu's question, he shook his head in embarrassment, "Battalion Commander, this cannon is not very accurate at aiming. Whether it can hit or not depends on luck." " Depends on luck? Damn it!" Jiang Fu shook his head helplessly, "Don't fight, it's just a waste of artillery. We only have a few guns left to attack Hangu Pass in the future." The sound fell silent, and at this moment, the city gate of Tianjiaping Fortress suddenly opened, and hundreds of Qin troops rushed out with shouts. Gouxin on the city could not bear such a passive situation, and launched a counterattack , his target is those engineers who are working. Gou Xin did not know the strength of the Han army. In his opinion, these engineers on the other side were just auxiliary soldiers. The auxiliary soldiers were always scum with a combat power of only 5. They caused a lot of damage to them. Boost your own morale, and secondly, it can also deter your opponents. Of course, he didn't know that the engineers of the Han Army were completely independent units, but when they had to step onto the battlefield, they were not incapable of fighting independently. Seeing Qin Jun rushing out, Jiang Fu finally became excited. "You son of a bitch, let me tell you, the Qin people won't always be cowards, it's a good time." He screamed with excitement. A company of soldiers who had been prepared quickly rushed forward, and the originally sparse formation of engineers working in the front also quickly gathered together. They did not bring knives or guns, but the engineer shovel in their hands was a piece of equipment in itself. The sharp weapon, the engineering shovel made of fine steel, was in the shape of a round fox. The two-foot-long wooden shovel was inlaid with a metal bayonet at the end. Seeing the Qin army approaching, these engineers quickly took a stick from their belts and inserted it into the jam. As soon as the mouth was closed, there was a click sound, and the engineer shovel turned into a one-meter-long machine that could be used as a machete. The divine machine crossbow that had never had a chance to attack before finally got the chance. The crossbowmen operated the divine machine crossbow. On both sides of the engineers, they began to aim at the Qin army on the opposite side. The sharp arrows flew straight towards them with a whistling sound. Towards the Qin army rushing out from the city. (Unfinishedto be continued. )
