Xiaoguan is one of the four natural barriers in the Central Plains. It is located at the mountain pass on the eastern foot of Liupan Mountain. It has been a battleground for military strategists since ancient times. The rulers of the past dynasties all stationed heavy troops to protect Chang'an. Surrounded by majestic peaks and deep valleys, it is easy to defend and difficult to attack. It is not an independent pass, but a complete defense system along the fortresses on the mountains. The unique natural geographical advantage makes it impossible for troops to deploy in front of the pass. No matter how many people come, they can only wind up the mountain along the dangerous road to finally reach Xiaoguan. The narrow and winding path is surrounded by towering mountain walls on one side and cliffs along the Wei River or Jing River on the other. The infantry can still line up two abreast, but the cavalry can only move slowly with the man in front and the horse behind. Rolling trees, falling rocks and rain of arrows, it is basically a road to death. As long as there are only a few teams of troops under the forts on the hilltops guarding Xiaoguan, they can shoot down the narrow road below from high up, covering all sides without any blind spots. Due to the steep terrain, if you want to get rid of the archers on the top of the mountain, you must first break through the more dangerous Xiao Pass against the unpreventable rolling trees, falling rocks and rain of arrows coming from all directions. Only with such a majestic pass and a long road can we easily block the invincible Turkic cavalry on the grassland. "It's a pity that Xiaoguan, where heavy troops were originally stationed, is now as quiet as a ghost land, with no trace of human beings and only the cold wind and setting sun. The setting sun was brilliant, illuminating the ancient and tall city walls as if they were covered in blood, and making the mountains and rivers rustle like mourning. Fengxiao appeared like a ghost in the empty Xiaoguan Pass, and sighed: "Fortunately, it is a male pass and not a male city. It is more than ten feet high and only twenty steps wide. Otherwise, I can't defend an entire city wall. Too busy." His tone was filled with deep hatred. Feng Xue and Shi Fei Xuan fell behind him and stood to the left and right. Feng Xue glanced at the valley in front of Guanqian with cold eyes and said nothing. Shi Fei Xuan sighed: "Li Yuan's chaos naturally led to the disorganization of the army's morale. In a short period of time, there was no hope of cohesion." On the way, the three of them encountered several groups of Li Tang's army that had withdrawn from Xiaoguan. Feng Xiaoxiao killed dozens of them in a row. The officers failed to prevent the army from withdrawing. Instead, the already scattered army almost collapsed and turned into a riot. The sunset in the distance was even redder, like a fire, burning the clouds angrily. A flag suddenly appeared, as if splitting the clouds, fluttering in the evening wind. The snake-like torch spread from the wilderness like a dragon, and the entire valley was illuminated by fire. Burn brightly. "Golden Wolf Flag." Master Fei Xuan Gujing Bubo's jade face changed slightly and said, "It's Jieli's Golden Wolf Army." Feng Xiaoxiao's eyes tightened. He was worried that the Turkic army was coming, so he didn't dare to get too entangled with Li Tang's army. It seemed that he was right. He hurriedly and slowly arrived at the unguarded pass first. If we arrive an hour later, I am afraid that this ancient pass will change its owner. At that time, the Turkic spirits will ride into the pass and gallop across the plains, with thousands of horses galloping, and even the gods will not be able to stop them. The three of them stood on the highest observation deck of Xiaoguan, watching from a high position as the Turks quickly set up camp in the last open area before entering the pass. Under the reflection of the setting sun and firelight, Feng Xiaoxiao's face looked very pale, and he said: "The number of troops in the camp is between 15,000 and 20,000. This must be just the vanguard. The main force of the Chinese army plus the rear army, there are at least 100,000." People. With such strength, they can defeat the prairie. I'm afraid the Jieli family can't hold back so many people. They must be the coalition forces of the prairie." Among the three, only Feng Xue's expression remained unchanged and he said coldly: "Whatever. There are many people but few people, and they can't spread out in front of the pass. At most, a few hundred people can be attacked at one time, and they will die." Feng Xiaoxiao smiled bitterly and said to himself: "A hundred thousand people are standing still! How many chickens can we kill if we hold them by the neck? Even if there are 100,000 chickens, a really desperate swarm can crush me to death. Besides, marching and fighting is not as simple as rushing in and fighting. "What are they doing?" Feng Xue pointed to the valley and asked in confusion. Feng Xiaoxiao stared for a moment and said: "They are logging and building a camp, that's not right" His expression suddenly changed and he said: "They are planning to set fire to the mountain! Jieli must have known that the Tang army had abandoned the pass, and this was probably just a precaution. If not, If people resist, they will not be able to prevent fire." Shi Fei Xuan looked at it solemnly and said: "If they set fire to the two mountains in the northeast, the flames will not directly threaten us, but the thick smoke will be blown by the wind. Let alone defend, it will be difficult for us to defend the city wall. "Stand still." Feng Xiaoxiao said: "If Li Tang's army had not evacuated, just push some rolling stones from the mountain, and they would die in large numbers. Not to mention burning the mountain, they would not even be able to set up camp. ¡± Master Fei Xuan lowered her head and remained silent. Feng Xiaoxiao continued quietly: "Li Yuan wrote a secret agreement in a letter to Jie Li: If you enter Chang'an, the people's land will return to the Tang Dynasty, and the gold, jade, silk and silk will return to the Turks. If you can save the ministers and not invade the people, the conquests will be made, and the children, jade and silk will be theirs." Khan has?. " His words were full of resentment, as if he were saying, "This is the family that you, Cihang Jingzhai, have supported with all your strength, and yet they are so virtuous. " You must know that when he and Shi Zhixuan, the two demons of the Demon Sect, were plotting and scheming, they tried every means to prevent the Turks from disturbing the situation! Li Yuan actually dared to invite foreign invasion, and did not care about the safety of the Central Plains. He only cared about his Li family. After the chaos was over, the imperial concubine Xuan sighed: "The deceased is dead, and the imperial concubine Xuan is irrefutable. " Of course the deceased refers to Li Shimin. She means that Cihang Jingzhai supports only Li Shimin, not the Li family. Feng Xiaoxiao sneered: "Even if he is not dead, Mr. Li will inevitably kill his brother and his father. Such behavior, I On behalf of the demon sect, it would be better to let him be the evil emperor. " "Those who have achieved great things in the past and present are all cruel and ruthless people. All obstacles blocking the throne of the emperor must be removed, otherwise you will not be qualified to be the emperor at all! My husband naturally knows this very well. "Shi Feixuan raised her head calmly, stared into Feng Xiaoxiao's eyes and said, "Feixuan has surrendered long ago. There is no need to argue about right or wrong. I only hope that my husband can leave some space for Fei Xuan and Fei Xuan's disciples to practice meditation in peace, but other than that, I don't expect much favor. " Feng Xiaoxiao looked at her clear and firm eyes and couldn't help but sigh inwardly, thinking: "Fei Xuan still cares more about her master. " Shi Feixuan seemed to be aware of what he was thinking. She took half a step closer to him, almost touching his arms. She lowered her head and said tremblingly: "If we were to change places, Feixuan would also leave a space for Feng Lang to relax and meditate. And accompany you" A few wisps of blush spread on her fair face. Although she was very close to Feng Xiaoxiao, she was still not used to showing her feelings in broad daylight, so she was inevitably shy. Feng Xiaoxiao gently held her hand. As expected, Feng Xue snorted coldly and scolded her with a double entendre: "The rats are so bold that they will inevitably die. "Suddenly, he grabbed a huge sword with a dark red glow from his back. He jumped down, his white skirt fluttering in the wind, like a fairy volleying in the air, grabbing a magic weapon and crashing into the world. Go around to the pass and explore first. Dozens of Turkic knights were all dumbfounded, and then their heads flew up in pieces, and the blood on their necks sprayed like mist, and it was actually brighter red than the sunset reflected in the sunset(~^~)
