When Quan Gai Suwen heard Li Er's confrontation with him like this, he naturally didn't make a fuss, so he shouted to the city tower: "Li Shimin, don't be arrogant, you only have 10,000 or 20,000 people. I see how you can resist the attack of my 80,000 people."

"Haha, let's talk about it when you can get close to the city." After Li Er said that, he turned around and whispered to Cheng Yaojin beside him.

"Spray all the hot air balloons for me, no need to regret the Thunder of Booming Sky. Today's goal is to capture Quan Gai Suwen alive and throw all the Thunder of Booming Sky. I want him to let Quan Gai Suwen know that he can't afford to offend the Tang Dynasty." Li Erdao.

After hearing this, Cheng Yaojin nodded repeatedly. It could be seen that when he was besieged that day, Cheng Yaojin felt that he had lost all his face and wanted to regain his situation through today's battle.

Just as Quan Gaisuwen's order was issued and the Goguryeo soldiers were holding shields to siege the city, Yuan Bowen suddenly shouted: "General! Look what is that?"

Quan Gaisuwen looked in the direction of Yuan Bowen's finger and realized that many giant objects floated out of the city at some time.

Quan Gai Suwen had never seen this thing, but he had heard of it. After attacking Goguryeo, Quan Gai Suwen received a secret report saying that there was a very powerful weapon in the Tang army, and that it could not even see clearly what it looked like, and that it could break the city and crack the soil. It was extremely powerful. If it exploded in the crowd, there would not even be a complete corpse.

Although I had a premonition that something was wrong, but now that things have come to this point, it is impossible to withdraw the troops. So Quan Gai Suwen gritted his teeth and shouted: "All the soldiers of the army will follow my orders, rush for me, break through the city gate, each person will be rewarded with ten taels of silver, capture Li Shimin, reward 100 taels of silver, and grant the title of Qianhuhou Hou!"

Hearing the beautiful wish made by Quan Gai Suwen, the soldiers holding the shield in front worked harder, just as if Quan Gai Suwen had just promised them, they would definitely get what Quan Gai Suwen had promised them.

But when the first thunder exploded in the Goguryeo soldiers' camp, Quan Gai Suwen regretted it. He really underestimated the power of the thunder. It was just a thunder that exploded the almost airtight shield formation. Some of the soldiers who were blown up died on the spot, while others did not die, but their legs and arms ran away, so they could only lie on the ground and wail.

In fact, Li Er had thought of sending the Thunder to attack the camp directly, but Li Er was afraid that if Quan Gai Suwen could not be killed in one blow, Quan Gai Suwen would be fled to Silla's city, and the Thunder would be useless, so Li Er still endured the Thunder to put the Thunder on the front battlefield.

Sure enough, the effect was very good. Not only did the shield soldiers in front of them all silly, but some of the cavalrymen who followed Quan Gai Suwen were also thrown away by the frightened horse.

"Everything is calm, and you're going to take it forward! Don't retreat!" Quan Gai Suwen's shout came, but the soldiers refused to take a step forward one by one.

Cheng Yaojin, who was on the hot air balloon, laughed when he saw this. At this time, he felt the benefits of the weapon gap, so Cheng Yaojin said to the soldier who controlled the hot air balloon: "Fly over his Quan Gai Suwen's head, I want to give him a big one."

After hearing this, the soldier quickly controlled the hot air balloon to fly towards Quan Gai Suwen. But Cheng Yaojin forgot one thing. The hot air balloon he was riding in was the command post inside more than a dozen hot air balloons, so when Cheng Yaojin moved, the rest of the hot air balloons hurriedly followed.

"General, look, those things are flying towards us!" Yuan Bowen shouted again.

Seeing the powerful hot air balloon flying towards him, Quan Gasuwen finally showed a trace of fear on his face, and then said, "Retreat, retreat quickly." After that, Quan Gasuwen pulled the reins and ran towards the rear.

"I want to run? Where are you running?" Cheng Yaojin said, then ignited a thunderbolt in his hand, and then threw it out.

There was another loud bang, and this time the thunder thunder exploded on the open space. Although it did not explode, the horse under Quan Gai Suwen was frightened and ran wildly. He didn't know where to take Quan Gai Suwen, but he didn't go towards the direction of the camp.

When the soldiers who were left behind saw that their masters had run away, they were not losing their armor, and they wanted to have two more legs to escape. The troops of tens of thousands of people were immediately in a mess.

Seeing the situation under the city, Comrade Li Er laughed loudly on the city tower.

"I didn't expect that this sky-booming thunder is not only a magic weapon for siege, but also a powerful retreat to the enemy. If someone comes, I will pass my military orders and all the soldiers will immediately go out of the city to pursue the enemy. Be sure to capture Quanga Suwen for me."

After Li Er finished speaking, he shook the cloak behind him and prepared to walk down the city tower.

"Your Majesty, what are you doing?" Zhang Nan asked in confusion.

"Of course I'm going to capture Quanga Suwen. Today I will capture him alive!" Li Er said this, a trace of viciousness appeared on his face. Although Quanga Suwen was scared away today and was likely to become a prisoner, Li Er was still worried about the 40,000 dead soldiers.

Li Er went down to lead the troops to chase them out, but Zhang Nan did not stop him. After all, all the Goguryeo soldiers are not interested in fighting, and Quan Gai Suwen doesn't know where to run, so Zhang Nan is not very worried about Comrade Li Er's safety.

Looking at Comrade Li Er who led the military academy students out, Zhang Nan thought about something on the city tower.

If the sky-booming thunder was exposed directly that day, it is very likely that Quan Gai Suwen would defend the city and use the people in the city as a cover, so that the sky-booming thunder would no longer work.

If the Sky Thunder was used for sneak attack yesterday, it would be possible for the Quan Gai Suwen to escape while the night was dark. So after thinking about it, it would be the most suitable time to use this Sky Thunder at this time.

Of course, Zhang Nan also felt that the gap between hot weapons and cold weapons was so great that if you want to conquer the city in the future, you only need to send hot air balloons to the air to seize air supremacy, and then have a carpet bombing. In this way, no matter what kind of troops the opponent is, they will only lose their armor. What the Tang Dynasty needs to pay is the sky-blasting thunder made of low-priced raw materials.

However, to Zhang Nan's surprise, none of the 80,000 soldiers in Goguryeo resisted, and none of them. Some of the uninjured people were controlled by the Tang army who had left the city before they even stood up.

It seemed that they were scared by the sky thunder, and they didn't even mean to resist at all. Some even knelt on the ground and couldn't get up, so they refused to get up. In the end, a few Tang troops dragged them to the temporary prisoner-of-war camp.
