Originally, Li Er wanted to rest in Qingzhou for one night before setting off, but that night, just as Li Er, Zhang Nan, Cheng Yaojin and others were discussing how to fight the enemy, they suddenly received an urgent report from the front line, saying that Quan Gai Suwen had already brought his troops, and Li Er had no choice but to order troops to support the front line overnight.

In fact, after failing to surround Li Er for the first time, Quanga Suwen wanted to take advantage of the victory to capture Li Er and capture Li Er in one fell swoop, but he was obstructed by the Baekje generals in the city. The reason was that the generals who led the troops of Baekje felt that they were being fooled. Quanga Suwen was not only the generals, but also the Baekje country.

Because when Li Er broke through the city, all the soldiers who went to fight against the enemy were Baekje soldiers, so the worst ones were Baekje soldiers. Only three or four thousand survived 10,000 people, while Goguryeo soldiers only lost a part of them when Li Er broke through. The Baekje general felt that it was unfair, so he went to find Tougasu-wen to argue. However, he did not expect that Tougasu-wen did not give Tougasu-wen the opportunity to argue. He directly surrounded and killed all the Baekje generals in the city, and the remaining Baekje soldiers did not escape Tougasu-wen's vicious hands.

More than a thousand people were all executed by Quan Gasuwen. Anyway, the value of Baekje soldiers had been drained, and Quan Gasuwen killed them just to reduce their burden.

But this delay gave Li Er time to escape. When Quan Gai Suwen personally led the team to the Tang Army camp, the entire camp had already run away.

Quan Gai Suwen naturally would not let Li Er, who had already been stripped of most of his troops, immediately returned to the city and ordered his troops and turned to Qingzhou to attack.

That's why Comrade Li Er led the team to the front line overnight.

By the time Li Er ran to the front line, Xihe and Xiruli had already fought hard with Goguryeo soldiers for a day.

"General Xihe, what's the situation now?" Li Er entered the city, and the first thing he did when he saw Xihe was to ask what the war was going on.

"When it comes to Emperor Tang, those Goguryeo soldiers were like sealed, constantly attacking the city gate. Before you came, the city gate had been broken, but we also fought them out again. Now they retreated, but they should still attack tomorrow. After all, most of the city gates are gone now, and the vacant places are completely supported by door-to-door knives." Xi He said.

After hearing this, Li Er couldn't help frowning. Li Er thought that the situation on the front line was not optimistic, but he did not expect that the war on the front line was so unoptimistic that even the city gate was broken. You must know that the city with a city gate and the city without a city gate are completely different concepts. Moreover, it was beyond Li Er's expectation to use the door-stopper so quickly.

The door-sticking knives in Xihe's mouth can only be used for temporary emergency treatment and cannot be used as a city gate.

The door-sticking knife trolley is an extremely strong two-wheeled vehicle. The body and the city gate are almost as wide as the city gate, usually between three and four meters. There are three or four wooden frames in front of the vehicle, and several sharp knives are fixed on each floor, and the body has long shafts. If the enemy breaks through the city gate, dozens of soldiers push the knife trolleys and plug the city gate.

For the long-term fierce battle to stick to the city, the city gate is hard to lose. This door-sticking knife truck is the most useful emergency weapon. But it is just an emergency. Just like a spare tire for a car, it can only be used after the regular tire is blown, but it cannot be used as a regular tire. When you arrive, you still have to change the regular tire.

But the tires can be replaced, but the city gate will definitely not be able to be installed in a short period of time.

"Your Majesty, let's send troops to the city tower tomorrow to guard it. At least we have the help of the Shenfeng Crossbow and the Sky Thunder. It is not easy for them to get close to the city of Goguryeo. When they get near the city, most of them will definitely lose money." Cheng Yaojin said.

"Well, that's it. I'll defend the city tomorrow. We couldn't open it there and use thunder to bomb the sky. It's different now. This time I must blow them up alone." Li Er said.

"Well? Qingquan, why haven't you spoke for a long time? Tell me about your opinion." Li Er said that there was something wrong. It turned out that Zhang Nan hadn't spoken.

"Oh, you are an expert, so I will naturally listen to you, but the emperor forgot something." Zhang Nan said.

"Oh? What is it?" Li Er asked.

"College of the Military Academy, Master, you pulled them out of Chang'an City, but they have never participated in a war until now." Zhang Nan said.

When Li Er heard Zhang Nan say this, he was speechless for a moment. As Zhang Nan said, Li Er pulled the elites of the military academy from Chang'an to Silla, and it was indeed a formal war.

Because when attacking Goguryeo at the beginning, they almost pushed the troops all the way, and there was no place where military academy students with only more than 100 troops were obtained. What's more, Li Er was reluctant to let his precious students carry weapons and charge into battle like ordinary soldiers. After all, they were all elites and would lead troops to fight in the future. If one or two were on such a battlefield, it would be a loss.

This is why military academy students are just cheerleading teams from the time they go on the expedition to now.

"Just say whatever you want to say." Li Erdao.

"Yes, what I mean is that the purpose of cultivating military academy students was not only to train generals who led the troops, but also to allow them to complete some tasks that soldiers could not complete at some time. Their frontal battlefield may not be very effective, but if they are sprinkled into the rear of the enemy, it will be a place that will turn the enemy upside down." Zhang Nan said.

"Continue to talk down." Li Er raised his chin and signaled Zhang Nan to continue.

"Yes, now I think it's a good time to use this group of special soldiers. As the saying goes, good steel is used on the blade, and to cultivate them is to allow them to cause the greatest losses to the enemy at the lowest cost. So I think they should be allowed to attack tonight."

"What do you mean is to let them harass Quan Gai Suwen's camp?" Li Er frowned.

"Yes, we have more than a hundred military academy students. We can use most of the soldiers to harass them, making them sleepless. Then we will divide two combat teams from this group of soldiers and lurk in the place where food and grass are stored behind them. When the war will come tomorrow, Quangasuwen's troops will definitely come out in full swing, but they never expected that there was a surprise soldier from behind them. When the battle was in front, it would be convenient to burn their food and grass. Without food and grass, even if Quangasuwen has a million troops, it would not be a concern. After all, people have to eat enough to fight, right?"

After Zhang Nan finished speaking, Li Er slapped his thigh and said, "Okay! This method is good, Qingquan, I ordered you to immediately select the trainees of the military academy. I will send them out of the city in person."
