"Boom!"

In the generation that exploded just now, there was another earth-shattering noise, and the entire city wall trembled. This time, the Goguryeo casualties were much less, but the walls continued to be damaged by Yan zhòng.

"Woo-poof-"

Yuangai Suwen spit out a mouthful of blood on the top of the city wall of Liaodong City, and then finally barely stood up from the ground.

When Yuangai Suwen escaped just now, he clearly felt a force coming from behind. And this force is very huge, as if a heavy hammer smashed into his back, causing him to spit out a mouthful of blood. And Yuangai Suwen also knew that this should be the wave of the explosion just now. Fortunately, I ran fast, otherwise I wouldn't have vomited blood, but would have fallen apart. Therefore, Yuangai Suwen can be regarded as an escape from death.

"It's okay to leave only a few people on the city tower, and everyone else will retreat for me." Yuangai Suwen said.

"Yes!"

Those Goguryeo soldiers hurriedly retreated, and they didn't want to face a weapon like the Tang Dynasty, after all, this weapon was too sharp.

"Keep blowing it up for me! Concentrate your fire, concentrate your firepower, and blow up the walls in the same place! Li Xiaogong shouted.

"Boom!"

Thirty flying thunder cannons fired shells again, and then uniformly hit one section of the wall. And this section of the wall has been blown up and is beginning to crack, and then the contents have begun to be revealed. And inside the bluestone shell outside, in fact, they are all ordinary bricks, not all of them are walls made of bluestone.

Originally, the Goguryeo people thought that it would be enough to have a bluestone wrapped outside, because the hardness of bluestone was enough to resist those catapults. After all, the power of the stones thrown by the catapult is also limited, so some bluestones are enough to block the boulders of the catapult. And in addition, the soldiers also have a variety of ample weapons to defend the city, which is enough to defend the city.

But now the Tang army actually used a flying thunder cannon, and suddenly blew up the shell of the bluestone, and then revealed the brick city wall inside. This is equivalent to breaking the eggshell, which is actually vulnerable at all, and it can't resist this flying thunder cannon at all.

"Good. I thought it was a big fork in this wall, but I didn't expect it to be an embroidered pillow and a bag of grass. We directly exploded it with bombs, since the layer of bluestone outside can't stop it, and these waste bricks inside can't support our cannon at all! Jingwen shouted.

Li Xiaogong next to him sighed and said, "With this flying thunder cannon, of course, it will be easy for us." But if we didn't have this thunder cannon, then I'm afraid we would have to fill it with human lives. ”

Although this bluestone has only one surface layer, its hardness has reached the peak of ancient times. So if it was the case in the past, it was simply impossible

As for Yuangai Suwen in the city, he was in a hurry, obviously feeling very dissatisfied with this situation.

"How's it going?" Yuangai Suwen asked.

And his entourage immediately said: "The Don army has concentrated all that unknown weapons to one point. That is, inside one of the walls. The bluestone on the outside of this section of the city wall has been shattered, and now the bricks inside are exposed. If we let them go on like this, then I'm afraid we won't be able to deal with it at all. Once the city wall collapses, then we are afraid that there will be a hole in the defense line, and we will really be unlucky. ”

"Then shall we go out to fight?" Yuangai Suwen asked.

"General, no. If we go out to meet the battle, then I'm afraid the Tang army is just waiting for us! You see, the cavalry of the Tang army has already begun to prepare, just waiting for us to go out to meet the battle. And our infantry is fighting with the cavalry of the Tang Army, then we are afraid that we are not opponents at all! The attendant said.

Now Yuangai Suwen is really unable to advance or retreat. Originally, Yuangai Suwen thought that this wall was enough, but now it seems that this seemingly incomparable city wall is actually not vulnerable at all. Under such explosive weapons of the Don army, the city walls did not have any resistance at all. It was only two rounds of bombardment, and the bluestone shell outside was smashed open. The bricks inside were exposed. And these bricks are not enough to be fired, and it is impossible to withstand the bombardment of these artillery.

And if you stay in this Liaodong City, I am afraid that after the Tang army breaks through a gap in the future, a large number of troops will also pour in. And Goguryeo currently has no more than 10,000 people in Liaodong City. And it is simply impossible to be the opponent of the hundreds of thousands of Tang troops. So if you stay, you're going to die. But if you go out and take the initiative to fight, this is also an act of death. Because the cavalry of the Don Army was able to crush them with a single charge.

Originally, Yuangai Suwen thought that his city was very strong and there would be no problems at all, so he did not ask for support from the rear. But now it's too late for reinforcements to arrive, because the city wall is probably going to be breached, so it's too late for reinforcements.

"My lord, retreat quickly! If we don't retreat, I'm afraid we'll all die here. Now the Tang army is missing one of the three, that is, we can retreat. But if we don't leave, we're really going to die here! The squire said.

And Yuangai Suwen sighed and said, "Okay! Fall back! However, after we retreated, we quickly asked my father to mobilize troops to fight a decisive battle with the Tang Dynasty. We are also waiting for them in Anshi. ”

Soon, the Goguryeo army in the city was also ready to retreat. After all, there are only about 10,000 people on his side now, but once he loses the protection of the city wall, he will be vulnerable. Originally, the rear wanted to send reinforcements to support them, but this was because Yuangai Suwen wanted to monopolize the credit of resisting the Tang army, so he didn't ask for reinforcements at all. So now they are doing their own thing, there are no reinforcements, and the city wall is not reliable, which allows the Tang army to pinch them to death at any time.

Yuangai Suwen left from the north gate, then looked at this Liaodong City, and scolded: "If it weren't for you relying on these mysterious weapons, I'm afraid that even if you come with a million troops, I would have a way to drain your blood." What kind of hero is winning with weapons? ”

No matter what Yuangai Suwen thought, they couldn't hold Liaodong City, so Yuangai Suwen could only retreat in order to ensure the strength of his men. And he plans to notify the rear to mobilize reinforcements, this time he will not slap his swollen face to fill the fat man, because the Tang army is not a soft persimmon. And Yuangai Suwen also knew that it was not reliable to defend the city at all, and he could only rely on the soldiers to concentrate on the decisive battle. Otherwise, it would be impossible to defend the city. (To be continued......)
