Forty kilometers north of Chang'an City, on the bank of the Weishui River, Yi Nan Khan and his two sons, Tu Lisu, Dadu Society, and a group of civil and military ministers of the Xue Yantuo tribe stood on the bank of the Weishui River, looking at the still flowing Weishui, and sighed for a while.

"Thirteen years ago, when the Eastern Turks were invincible, we could only look up to the supreme demeanor of Jieli Khan. But who knew that this old guy was actually defeated by a small Weishui, which is really sad and lamentable! Yi Nan sneered.

The eldest son, Tu Lisu, immediately sent a sycophant: "How can Jieli Khan compare with his father, he has no force at most, but he has no strategy." They have all been killed in the capital of the Tang Army, and victory is just around the corner, and they will choose to make an alliance with the Tang King, which is simply ridiculous! Now, we will definitely not repeat the mistakes of the past, and we will set foot in Chang'an and enter the Central Plains! Achievement of father's supreme feat! ”

Obviously, the eldest son's words slapped Yi Nan's heart, and he immediately laughed, and the smug look on his face was not concealed at all, and the good country in front of him was already in his bag.

When the second son saw that the eldest was praised and won his father's concern, he suddenly became anxious, and hurriedly jumped out and said: "Father, the next step will be led by the son!" The son himself opened the gate of Chang'an City and welcomed his father into Chang'an! ”

The eldest son, Tu Li, refused to give in at all, and also asked Yi Nan to let him go on the expedition and capture Chang'an!

"No!" Yi Nan waved his hand, stroked his beard, and looked ahead, the aggression in his eyes was not hidden. "I will personally lead my troops to capture Chang'an! Become the Great Heavenly Khan! ”

Behind him, the civil and military generals of the Dadu Society suddenly knelt down on one knee and greeted: "The king is a hero, and the great cause is unparalleled!" ”

"Hahaha!" Yi Nan laughed, drew his sword and shouted: "Army! Let's go! ”

The 150,000-strong army crossed the Weishui and went straight to Chang'an like a black tide.

The scouts sent back information early, Chang'an City was under martial law, the drawbridge was raised, and the city gate was blocked. And the soldiers on the city wall held Chen Fei's newly invented "telescope" to carefully observe every move in the north.

Cheng Biting Jin, Yu Chi Gong, and Duan Zhixuan, the three black old carbons, sat on the city wall with a big grin, waiting for the arrival of the Xue Yantuo tribe.

At the same time, the three big bosses were not idle, scolding and scolding the soldiers on the city wall, shouting for them to prepare city defense weapons.

In the distance, the dust was thick, and a large army was hurrying towards Chang'an.

The soldier who was observing with a telescope hurriedly reported: "Report! A large army of enemies has appeared ahead! The enemy army is coming! ”

Cheng Yanjin immediately gave the soldier a potsticker with big ears, and said angrily: "Mahler is a target!" Are you blind? Such an obvious enemy, the old man will not be able to see it? Why don't you hurry up and carry the rocks to prepare for the enemy? ”

"Yes!" The soldier was slapped and honestly went elsewhere to carry the stones.

Cheng Yanjin and the other three veterans stood on the wall, looked at Xue Yantuo's army in the distance, and said solemnly: "Good guy! Yi Nan has brought out Xue Yantuo's old book! 150,000 troops! Tsk, what a reluctance! ”

Wei Chigong touched his beard and said with a smile: "Haha, it's good that it's all here, let Yi Nan remember it well, follow the example of Jieli Khan back then, and there will be only one end!" ”

Duan Zhixuan smiled sympathetically: "I heard that Yi Nan has already suffered a loss of thunderbolt fire when he attacked the frontier, and he is quite afraid of this thing, and he has sent a vanguard army to test it carefully when he attacked the city later, I don't know what his mood will be when he learns that we have prepared 100,000 thunderbolts this time?" ”

At this point, the three old foxes laughed at the same time.

Even if a single thunderbolt can only kill one person, 100,000 thunderbolts are enough to kill 100,000 soldiers.

The last thing that Chang'an City lacks is thunderbolt fire! Li Shimin has piled up a large amount of inventory in Chang'an City!

If Yi Nan knew that the stock of thunderbolts in Chang'an City had reached 100,000, he would probably be so frightened that he would turn around and run away, right?

100,000 thunderbolts! How to play? You're hanging up, aren't you? Is there such a brazen cheat?

"Don't use thunderbolts to make Yi Nan think that we don't have many thunderbolts, hang him to his appetite, and when his army is pressing, throw thunderbolts violently, enough for him to drink a pot!" Cheng Yanjin came up with an idea of yin damage, which was unanimously applauded by the other two old foxes.

Poor Yi Nan, completely unaware that he was calculated, stupidly led the soldiers to Chang'an City, he gave an order to his two sons, "You two each lead 50,000 troops to attack the east and west walls of the city, whoever captures the city wall first, the position of the future khan will be his!" ”

Tu Lishu and Dadu Society suddenly turned red-eyed, the throne of the Khan! Isn't it true that the two brothers are secretly fighting to the death just to inherit the throne of the Khan in the future? Now that the opportunity is in front of you, how can you not work hard?

The two glanced at each other, and then hugged their fists and said: "Father, don't worry, the child will definitely break through the wall of King Tang!" Help your father reach the top of the Heavenly Khan! ”

The two snorted in defeat, and then each led his soldiers to besiege the east and west walls.

"The enemy has divided his troops, and he is surrounded by three and one, hum! I really don't know whether to live or die! Duan Zhihong sneered.

"Let's go, go to your respective city walls, don't hinder my old Cheng from playing!" Cheng Yanjin stared at the Xue Yantuo soldiers galloping in front of him and said excitedly, the battle was imminent, and his blood was boiling.

Yu Chigong and Duan Zhihong laughed when they saw Cheng Biting Jin's appearance, and scolded with a smile: "Old guy, take it easy, don't flash your waist later!" Let's go! Timely report of the situation! ”

With that, the two veterans returned to their respective walls and organized preparations for defense.

Ten miles, nine miles, eight miles, five miles, three miles, and one mile

Cheng bit Jin suddenly burst into his tongue and shouted: "Siege crossbow!" Put it on Lao Tzu! Archers prepare, once the enemy is in range, shoot Lao Tzu with arrows to kill the fuck! What about the cannons? It's all on the shelf for Lao Tzu, and it's big towards the place where there are many of them! Don't tell Lao Tzu that you don't know how to use this thing yet, and Lao Tzu will stuff you into the barrel and shoot you out! ”

Xue Yantuo's army rushed towards Chang'an City with a strange scream, and five miles away from Chang'an City, powerful siege crossbows attacked them first. A crossbow bolt pierced through the three soldiers, and a blood flower floated by, and the three soldiers were pierced by the arrow and shot to the ground, trampled into pulp by the following soldiers.

At the same time, dozens of cannons on the city wall let out a roar, and dozens or hundreds of cannons smashed into Xue Yantuo's army.

The dense army was overturned on their backs by the artillery, and there were countless casualties. The menacing army suddenly became angry and made a mess!

Yi Nan was shocked and immediately ordered to stop the march, and the army watched uneasily from a distance of four hundred meters from Chang'an City, and did not dare to advance.

Cheng Yanjin stood on the city wall and laughed, snorted at Yi Nan, and mocked: "Yi Nan Xiaoer,." The old man Cheng bit the gold, and if he has the ability, he stepped on the old man's corpse and went in! ”
