Under the city of Pyongyang.

The boys in Yuan led a cavalry team to assemble within the city gate.

The eldest son of the Yuan family was wearing two armors. The armor was very ancient and full of literary style of the generals of the Wei and Jin dynasties. The armor leaves on the left side of the chest were decorated with gold and silver pieces, which were gorgeous and practical.

"The eagles in Haidong, advance! Use your claws to tear the enemies in front of me!"

The boy Yuan yelled and looked ahead, and the city gate slowly opened: the Tang army's stone-throwing chariot formation was more than 200 steps away from the city gate, and his cavalry could reach near with just one sprint, and he had to withdraw before the opponent's cavalry could react.

They had already seen the Tang army's field battles, and even the boy born in Yuan did not dare to confront the Tang army's elite cavalry head-on.

As soon as the boy's cry fell, the soldiers around him roared.

These are all the closest deceased soldiers of the Yuan family. Despite the bad situation, they still maintain strong fighting spirit.

Accompanied by this indescribable roar, a crowd of people jumped out of the door.

Just as the gate of Pyongyang City opened, Yoon Gai Suwen on the city tower keenly noticed that soldiers were transferred on both sides of the Tang army's rock-throwing chariot formation. Looking carefully, he suddenly became angrily and was at a loss. He hurriedly shouted: "Come back, come back."

But it's too late!

The cavalry team led by the Yuan boy flew across the moat bridge and rushed towards the rock-throwing chariot formation like a whirlwind.

Two hundred steps, one hundred and fifty steps...

Just as the boys in Yuan rushed into one hundred steps, the two teams of soldiers on the left and right of the stone-throwing chariot were divided into three columns. They were half-squatting on the ground in the front row, holding the already loaded Fuyuan crossbow in their hands.

Crossbow arrows all over the sky came through the sky!

A row!

Two rows!

Three rows!

Three-stage cross-shooting!

The effective range of Fuyuan Crossbow is 300 steps, which is the most lethal at a distance of these 100 steps.

In just a few short breaths, the Goguryeo cavalry team rushed out was neighing to the shooting horses.

This kind of cross-left shooting has nowhere to dodge.

This was even more so for the boy Yuan to take the lead. Three powerful crossbow arrows directly penetrated his body, and the powerful force took him out of the way. He fell to the ground and couldn't even shout a word.

The Liangdang armor is indeed strong, but it is also vulnerable in front of the crossbow arrow with extremely strong penetration.

The firepower net arranged in cross-fire directly shoots Goguryeo's cavalry team into an incompetent state.

Especially the arrow headed by the boy in Yuan was instantly destroyed and was concave.

The sound of retreating gongs sounded at the city wall in Pyongyang County.

This encounter caused more than 300 cavalry damage, and even the generals were killed. The remaining cavalry all scattered and lost the most important impact of the cavalry.

Yuan Gaisuwen also noticed that spearmen had already lined up in front of the casting array and took protection.

The Tang army had planned it from the beginning and had long expected that they would specially arrange cavalry to leave the city.

Li Yuanai turned around and gave a thumbs up to Zhang Jinshu beside him.

Before this war, Li Shimin transferred Zhang Jinshu to Li Yuanai and asked Zhang Jinshu to cooperate with him to attack the city.

Li Yuanai still had never heard of this name, but there were too many famous generals in the Tang Dynasty, so he dared not underestimate it and patiently asked for tactical and tactical methods.

Zhang Jinshu is fifty-six years old this year and is a real veteran. At the end of the Sui Dynasty and the beginning of the Tang Dynasty, he was a general of Gao Kaidao, and later killed Gao Kaidao to surrender to the Tang Dynasty. His resume was not glorious. However, he joined the army at the age of fourteen and fought for 40 years, and was well aware of various tactical methods. During this Eastern Expedition, he followed Zhang Liang to lead the navy to fight in a roundabout way, but he did not get any credit.

Li Shimin knew that he was unfair to the navy soldiers, so he asked them to cooperate with Li Yuanai to make contributions.

Zhang Jinshu has no less than ten methods in his mind about how to restrain the catapult car.

Put yourself in your shoes and make targeted arrangements one by one, which will be effective.

Zhang Jinshu said: "That is, in Goguryeo, this method can be implemented. If it were my Tang Dynasty, it would not be so easy to deal with."

Li Yuanai asked a little more, "Why?"

Zhang Jinshu narrowed his eyes and said, "The horses on Goguryeo are mostly mountain horses, suitable for walking rugged bends. They have good endurance, but they have no explosive power. If they were the Liangzhou horses in our dynasty, the gap between these two hundred steps was just a few breaths. In general, the crossbowmen had no time to react, so they rushed to the vicinity. The Liangzhou horses lacked enough endurance and were not suitable for long-term battles. However, they charge and attacked positions in surprise, but they were invincible."

Li Yuanai stopped nodding and wrote down.

As they were talking, the rock-throwing cart cast a third wave of huge rocks.

Before he could even feel sad, Yoon Gaisuwen shrank his head into the battlement, and was weak all over. He punched the battlement, cursing: "Damn it!"

Yuan Nanjian's eyes were blushing. He had a bad relationship with his elder brother. When he saw him tragically die today, he couldn't help but feel sad and gritted his teeth and said, "Don't worry, my father, it's not easy to collect cannon stones, so I don't believe that they can smash them all day."

At dusk.

Yuan Gaisuwen sat behind the battlement weakly, and glanced at his second son weakly. Tang Jun really smashed him for a whole day!

Tang army soldiers should eat and drink, but the cannon stone rain is always launched steadily.

On this day, tens of thousands of flying stones directly filled the moat of Pyongyang City. None of the houses close to the city walls were complete. Even the western corner north of Pyongyang City was smashed, and if it was smashed like this, the Tang army would collapse the north of Pyongyang City without any soldiers.

During this long period of time, Yuan Gaisuwen tried his best to destroy the phalanx of the Tang army's catapult chariot, and all of them were resolved by the Tang army one by one.

Zhang Jinshu may not be a famous general, but he has no less than a hundred experience in defending and sieging the city in his life. He knows the skills of attacking and defensive casting cars and does not miss any opportunity.

"what to do?"

Yuan Gaisuwen is so exhausted.

"No, no, Tang army, Tang army is coming into the city!"

Yuan Gaisuwen was thinking about a plan to break the enemy. He suddenly realized that the Tang army had entered the city. After a moment of loss, he exclaimed: "How is it possible? Silla, isn't Baekje not siege?"

"It's the East Gate, the Tang army rushed in from the East Gate!"

It turned out that Yoon Gassuwen's powerless resistance was spread to the royal palace of Goguryeo in the city.

The dignitaries and nobles in the Goguryeo Palace were unstable. They thought that hiding in the city would inevitably die, so they might as well run out of the east gate.

Especially Gao Zang, who had always been a puppet for Yoon Gaisuwen, intends to imitate the restoration of Goguryeo at that time, hides in the corner of the mountain dock, and waits for the Tang army to retreat, and then raises his arms and calls out again.

Their group decided to go out of the city while the chaos was in trouble.

Although there were guards at the East Gate, they did not dare to really attack King Goguryeo, so they could only let him go.

As a result, the people and ministers flocked to the east gate, and the east gate was in chaos.

The Tang cavalry, who had long been hiding in the dark, took advantage of the opportunity to enter the city and controlled the east gate in one fell swoop.

"Three circumferences are missing one!" This thought came to my mind, and I looked as if everything I had worked hard to disappear. I smiled miserably and jumped down from Pyongyang City.

"Father!" Yuan Nanjian exclaimed, then shook his head bitterly, and followed his father's footsteps.

The north gate of Pyongyang City is wide open!
Chapter completed!
