Li Shimin said to Hou Junji: "Yao Gu, you are the most familiar. Fight well and annihilate the 30,000 army led by Yarkin. The better you fight, the more completely you annihilate the enemy, the safer Chang'an City, the capital of the Tang Dynasty, the safer I will be, and the safer your daughter Haitang will be. After that, the Tang Emperor Li Shimin calmly encouraged the army to go out, and watched the army walk out of the gate of the Tang Emperor's capital with high morale and generosity, and walked to the boundless night, and walked to the ambush place of Yao Valley.

Hou Junji led the left and right Qianniuwei army to leave, and Chang'an, the capital of the Tang Dynasty, really became an empty city, and the army guarding it was only the Zuojin Wuwei army led by Chai Shao, the general of Zuojin Wuwei, with less than 10,000 people. Li Shimin, the emperor of the Tang Dynasty, looked at the boundless night sky and felt endless pressure, after all, he was facing the invasion of an army of 400,000 led by the Turkic Jieli Khan. But he couldn't stop, so he could only do his best to lead the civil and military officials and the people of the Tang Dynasty to fight for that glimmer of life. An inattentive negligence, that is, the fall of the imperial capital Chang'an, the subversion of the Tang Dynasty, Li Shimin is like a person walking a tightrope between the cliffs, under endless pressure, but he maintains a sober sanity and does not dare to take a wrong half a step.

Late at night, in the Lizheng Palace, Empress Changsun and Concubine Yang were organizing the palace people to rush to make the Tang Dynasty banner used to arrange suspicious soldiers all night.

Beside Empress Changsun, Concubine Yang, who was carefully sewing the flag, asked Empress Changsun worriedly: "Sister, can we win this battle?" This time, the Turks came with nearly 400,000 people, and my Tang Chang'an now has less than 10,000 troops. ”

Before Empress Changsun could speak, a childish voice replied, "We can definitely win, my father is the bravest warrior in the world, and he has never lost a battle. No matter how many enemies come, my father will be able to defeat them. ”

Concubine Yang followed the voice and saw a little girl with pigtails and green silk clothes, pink and tender, but her expression was extremely firm.

Empress Changsun summoned the little girl to her side and introduced to Concubine Yang: "She is Hou Junji's only daughter, Hou Haitang. ”

Concubine Yang suddenly showed a hint of realization, the Tang Emperor Li Shimin and Hou Junji were not only monarchs and ministers, but also brothers who trusted each other in life and death. Hou Junji has always been the confidant of the Tang Emperor, the most staunch supporter, for the sake of His Majesty the Tang Emperor, Hou Junji's family has suffered a great disaster, and now only this only daughter is left.

Concubine Yang took Hou Haitang's little hand and gently hugged it in her arms, spoiling her.

At this moment, another immature voice sounded, "Yes, our Datang will definitely be able to defeat these hateful Turks." I saw that my father had ordered the palace to prepare a celebration wine, and my father was the most powerful person in the world. I believe that no one in this world can defeat my father. ”

In the main hall, everyone looked at Li Chengqian, the prince of the Tang Dynasty, who was carrying the flag, they didn't expect that the young Li Chengqian would have such confidence in the war, and Hou Haitang, who was held in the arms of Concubine Yang, looked at Li Chengqian with admiration, and she deeply agreed with Li Chengqian's words. It's just that she didn't expect that there would be someone more powerful than his father in this world.

Empress Changsun looked at Li Chengqian and Hou Haitang with interest, and said to Concubine Yang with a smile: "After so many years, don't you know your majesty?" When did Your Majesty say you can win a battle that you can win? Qian'er can trust his father so much, and Haitang can trust his father so much, can't we fully trust our husband? ”

Concubine Yang looked guilty, and smiled helplessly: "What's wrong with me?" I have always believed in His Majesty, and I have no doubt about His Majesty, but today's performance is not as good as that of two children? ”

Early in the morning, Yao Valley. Hou Junji looked at the unique terrain of Yao Valley, and he showed a cruel smile. Here is the only way from Jingyang to martial arts, both sides are the vast alpine dense forest, the slope is not steep or slow, the forest is not dense and not Xi, it is easy to conceal, it is more convenient to charge, between the two ends is the only passage, here is really the ambush wonderful place that is difficult to find in the world. Hou Junji ambushed 3,000 infantry at both ends of the Yao Valley, at the entrance and exit, to intercept them; The remaining 17,000 cavalry were all ambushed between the high mountains and dense forests on both sides. This time, Hou Junji was also ruthless, he wanted to completely eradicate the 30,000 troops of Yarjin on the left side of the Turks, and not one of them would be left! He gave the most severe orders to his subordinates: whoever dared to let go of a Turkic cavalryman should exchange his head for it!

At noon, the Turkic army of 30,000, under the leadership of Yarjin, the commander of the Left Route Army, wore leather robes and brandished scimitars, and roared into the Yao Valley. They didn't expect that there would be an ambush by the Tang army here, and this would become their burial place. When the canyon of nearly ten miles was loaded with the 30,000 Turkic army, the war drums in the dense forests on both sides of the bank suddenly rose, the horns of the bull horns roared violently, the rolling wood and thunder stones mixed with the rain of arrows rumbled down, and the entrances and exits at both ends were quickly blocked by the Tang Dynasty soldiers. The Turkic cavalry was caught off guard, swirling like a tide, and the front and rear passages were closed, and there was no way to retreat or escape. On the high mountains on either side, rows of eight-bull crossbows emitted a terrifying sound, followed by a series of terrifying screams from the Turkic cavalry falling in pieces.

When the rumbling war drums rolled all over the mountains like thunder, Hou Junji, the general of Zuo Qianniuwei, pulled out the sword at his waist and said in a high-pitched and passionate voice: "In this battle, the general will require me to leave and right the Qianniuwei army, 'horses will sweat, swords will see blood, and people will be wounded', and after the battle, if they do not meet the requirements of the general, they will be killed on the spot." As he spoke, he pointed his sword at the clueless Turkic cavalry who were running in all directions and said: "For the sake of the Tang Dynasty, for the sake of Sheji, for the innocent people of the Tang Dynasty who were slaughtered by the Turks, kill!" ”

"Kill!" The soldiers of the Tang Dynasty erupted into a blood-boiling shout, and the troubled Turkic army poured into the past from all sides.

When the black-pressed Tang army poured over from all directions, the Turkic cavalry suddenly fell into a panic. Yarjin and a group of Turkic generals were so panicked that they simply didn't know which direction to give the order to flee? Soon, they felt desperate, they knew that in this kind of canyon terrain ambush, and all-out charge, Datang obviously wanted to kill the killers, to kill them all, cut the grass and eradicate the roots.
