Just do it, the Tang Dynasty siege methods have long been moved to the military department's small classroom, basically the generals of the military department will remember the tactics of the thunder siege, the ironclad car stepped forward to bury the mine, set up the lead ignition exit, and the army of the city wall was killed, this set is simply incomprehensible, and even the casualties have been greatly reduced.

Of course, this was before the advent of cement, in the past, the world was all brick walls or earthen walls, and now there is an earthen wall outside Goguryeo Pyongyang, and I don't know how many cement walls are inside, so according to the plan, the ironclad car will be regarded as a propaganda vehicle, which is terrifying.

"The Goguryeo soldiers in the city listen, we are the heavenly soldiers of the Tang Dynasty, and the entire territory of Goguryeo has been occupied and taken over by our Tang Dynasty, and only a lonely city in Pyongyang is still resisting.

You are limited to open the city and surrender within half an hour, otherwise we will break the city with thunder, and you will either die or be taken prisoner.

My Majesty Datang is a great grace, and he is the most kind to the people, knowing that you are just a soldier to eat and live, so those who take the initiative to surrender in this battle are not considered prisoners, and they can all go to my Datang to be a wealthy person and live a peaceful life as an ordinary person.

Half an hour later, our army began to attack the city, and those who did not surrender were waiting for the thunder. ”

After shouting, a few grenade-like thunderbolts were thrown from the ironclad car for demonstration, and the earth-shattering sound exploded directly in the hearts of the city defenders, watching the earth and rocks on the ground fly over a huge crater, and no one believed that Pyongyang's city walls could withstand it.

Soon, the ironclad car slowly retreated, and there was a lot of discussion on the city, including the soldiers in the gate cave guarding the city.

The most interesting thing is the guards and soldiers on the east city gate, this guard is the son of the Cui family, and the soldiers are the private soldiers of the Cui family, looking forward to the arrival of the Tang Heavenly Army.

Who knew that the Tang army would come so quickly, but when they came, they didn't attack the city, they actually stationed outside the city for two days, and they didn't come to communicate with each other to agree on a code or anything.

Now the four walls are shouting, what does this mean? I don't like that our Cui family should not be enough, do you want the whole city to be your internal response? Why don't you go to heaven? This is the old nest of Yuangai Suwen, the old nest of Goguryeo, not to mention that the whole city is diehard, at least half of the city is diehard.

The guard at the head of the city was depressed, he was just stationed at the east gate with his family's private soldiers, and he didn't know the situation of the other three gates, if he opened the door and surrendered now, it was estimated that he would not wait for the Tang people to enter the city, and he would be strangled by other armies in the city.

Yuangai Suwen personally stood at the head of Xicheng to watch the battle, and saw that his subordinates were panicked because of the Tang Dynasty's scheming, and now there is no good way, so he can only strictly suppress it, and if there is a change, he will be killed.

Half an hour later, Cheng Biting Jin gave an order, and the sea and land armies were combined with a total of 75,000 men and horses, leaving 5,000 to defend the Chinese army, and the other 70,000 were divided into four teams and followed the ironclad chariots forward to attack the city.

Seeing that none of the soldiers at the head of the city on all sides surrendered, Cheng Yanjin had no choice but to really attack the city, but Hou Junji urged him to just attack and first break through the first line of defense of Goguryeo-the old city wall.

Since Goguryeo got cement, it built the second and even third cement walls in the city, just to withstand the thunder of the Tang Dynasty, Pyongyang is the capital, and Yuangai Suwen even built three inner city walls.

And you can't see it from the outside, it's still the original brick wall of the old city, so it can't withstand the attack.

When the ironclad car of the Tang Dynasty drove to the bottom of the city, the guards of the city on all sides of Goguryeo remembered the military report given by the military, and knew that the Tang Dynasty had a sharp weapon to destroy the city wall, and the ironclad car was going to move seriously, so he immediately stopped holding on, greeted him, and withdrew to the second line of defense with the defenders of the city.

The defenders at the head of the city were puzzled, thinking that the general would let us defend the city desperately, why did they retreat without letting go of an arrow?

It is impossible for the guards to explain to the soldiers one by one the thunderous bombing of the Tang Dynasty, after all, no one has seen it or imagined, so in the whispers of tens of thousands of private soldiers in the first few hundred thousand private soldiers of Goguryeo City, the old city wall in front of them was directly under a roar, and the bombed earth and stones were flying and dusty all over the sky.

The soldiers defending the city swallowed and spat at the mouth, this, this thunder is so powerful, the city wall was destroyed and torn apart, if you didn't leave just now, and you are still standing on it, is it not even a dead body?

It's not just the soldiers who think so, it's that the generals know the result in advance, but when they really see it, they break out in a cold sweat in their hearts, such a power, can the second cement wall withstand it?

Although Goguryeo has cement and has done cement hardness tests, it has not been tried with thunder, after all, the Datang thunder is an exclusive secret recipe, so at this time, the guards have no bottom in their hearts.

The smoke and dust dissipated, the old city walls on all sides were blown up, and outside the huge gap, the Tang army roared forward step by step under Cheng Biting Jin's order, with the ironclad car, looking at the second city wall in front of them, the Tang soldiers were full of confidence, Goguryeo was simply brainless, thinking that the two walls would be fine?

I think this way because the Tang soldiers don't know the power of the cement wall yet.

At this moment, before the battle started, the second round of ironclad mine-laying vehicles had not yet reached the city, and three of the city gates on all sides directly opened the city gates and shouted surrender.

Only the West City Gate was not opened, not because the West City Gate was a Goguryeo diehard, in fact, even if it was a diehard, in the face of the death of no bones, no one was not afraid, the West City Gate Cave was divided into two groups of people who had already fought, one group wanted to surrender and survive, and the other group was desperate to carry out the king's order to defend the city.

Cheng Yanjin and the others looked at it, good guys, before they could get serious, Pyongyang City surrendered on three sides?

"Hey, monkey, look at this, didn't you expect it a long time ago?" Cheng Yanjin asked.

"Yes, eight or nine are not far from ten, in our eyes, there is a world of difference between the old city wall and the cement wall, but these Goguryeo soldiers don't know, not to mention that it is still a group of hastily assembled private soldiers, so this blowing up the old city wall is the last move of our scheming and the last straw that crushes the camel.

The city is broken on three sides, the general trend has been decided, Lao Cheng, the next villain will be handed over to you to do, I will show you that there are no fish out of the net.

Lao Hei, it seems that there is the enemy commander on the western city wall, Goguryeo is against Lu Yuan Gai Suwen, and this credit is given to you. ”

Cheng Yanjin nodded, raised the horse lance in his hand, and rushed into the south gate with all his right guards.

And after Wei Chigong said a concession to Hou Junji, he led people to enter from the north gate, wanting to then storm the west gate and capture Yuan Gai Suwen.

As for why Hou Junji didn't take credit at this time, in fact, breaking the city is a great achievement, and the rest is out of oil and water, so it's still a trouble to say that it's not good, so it is the best policy to surround the town guard outside.
