Originally, Li Er wanted to rest in Gyeongju for a night before setting off, but that night, when Li Er, Zhang Nan, Cheng Yanjin and others were discussing how to resist the enemy, they suddenly received an urgent report from the front line, saying that Quangai Suwen had already brought troops to come, and Li Er had no choice but to gather troops and horses overnight to support the front line.

In fact, after the first failure to besiege Li Er and Li Er's breakthrough, Quangai Suwen wanted to take advantage of the victory to pursue 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 in Baekje felt that they had been tricked, and Quangai Suwen was not only a general, but also Baekje.

Because when Li Er broke the city, all the soldiers who went to defend against the enemy were Baekje soldiers, so the worst death was also the Baekje soldiers, only three or four thousand of the 10,000 people survived, and the Goguryeo soldiers only lost part of it when Li Er broke through, and the Baekje generals felt that it was unfair, so they went to find Quan Gai Suwen theory, but they didn't expect that Quan Gai Suwen did not give the Baekje generals a chance to theorize, and directly besieged all the Baekje generals in the city, and the remaining Baekje soldiers did not escape the poisonous hands of Quan Gai Suwen.

More than 1,000 people were all ordered to be executed by Quangai Suwen, anyway, the value of the Baekje soldiers had been squeezed out, and Quangai Suwen killed them just to lighten his own burden.

But it was such a delay that gave Li Er time to escape, and by the time Quangai Suwen personally led the team to the Tang army camp, the entire camp had already run out.

Quangai Suwen naturally would not let go of Li Er, who had already cut off most of his troops, and immediately returned to the city to gather his troops and horses to rush towards Gyeongju.

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

By the time Li Er ran to the front line, Xi He and Xi Ruli had already led their soldiers to fight hard against the Goguryeo soldiers for a day.

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

"Back to the Tang Emperor's words, those Goguryeo soldiers are like sealed, constantly attacking the city gate, the city gate has been broken once before you come, but we also beat them out again, now they have retreated, but tomorrow should be a hard attack, after all, most of the city gate is now gone, and the vacant place is completely supported by the Saimen knife car." Xihe Road.

Li Er couldn't help frowning after hearing this, Li Er had thought that the situation on the front line was not optimistic, but he didn't expect that the war on the front line was so unoptimistic, and even the city gate was breached. And the use of the Saimen knife car so quickly was also unexpected by Li Er.

The Saimen knife cart in the mouth of the former and the mouth can only be used for temporary emergency relief, and cannot be used as a city gate.

The Saimen knife car is an extremely strong two-wheeled vehicle, the body of the car is almost the same width as the city gate, and it is usually between three or four zhang; There are three or four layers of wooden frame in front of the car, and each layer is fixed with a number of sharp knives, and the car body has a long wheel; The enemy broke through the city gates, and dozens of hundreds of soldiers pushed knife carts to block the city gates.

For the long-term fierce battle of holding the city, it is difficult to protect the city gate without losing it once, and this Saimen knife cart is the most useful emergency weapon. But it's just an emergency, just like the spare tire of a car, which can only be used after a puncture of the main tire, but it cannot be used as a regular tire, and it is necessary to change the regular tire when you get to the place.

However, the tires can be replaced, and the city gate will definitely not be erected in a short time.

"Your Majesty, tomorrow we will send troops to the city tower to guard it, at least we have the help of kamikaze crossbows and thunderstorms, it is not easy for them Goguryeo to get close to the city, and when they get to the vicinity of the city, they will definitely lose most of it." Cheng bites the golden road.

"Well, it's so decided, tomorrow we will defend the city like this, at that time we couldn't open up and use thunder over there, but now it's different, this time I must blow them up and turn them on their backs alone." Li Erdao.

"Huh? Qingquan, why don't you talk for a long time? Tell me your opinion. Li Er said that he felt something wrong, and it turned out that Zhang Nan had not spoken.

"Oh, the emperor, you are an expert, and the ministers naturally listen to you, but the emperor has forgotten something." Zhang Nan said.

"Oh? What is it? Li Er asked.

"Cadets of the military academy, Your Majesty, you pulled them out of Chang'an City, but they haven't participated in a war until now." Zhang Nan said.

Hearing Zhang Nan say this, Li Er was also speechless for a while, as Zhang Nan said, after Li Er pulled the elites of the military academy from Chang'an to Silla, it was indeed a regular war that had not been fought.

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

This is why cadets have only been cheerleaders since they went out.

"Say whatever you want." Li Erdao.

"Yes, what the minister means is that the purpose of training military cadets at the beginning is not only to train generals who lead troops, but also to let them complete some tasks that soldiers can't accomplish at some time. Zhang Nan said.

"Go on." Li Er raised his chin and motioned for Zhang Nan to continue.

"Yes, now the minister thinks that it is a good time to use this group of special soldiers, as the so-called good steel is used on the blade, and the purpose of cultivating them is to let them inflict the greatest losses on the enemy at the lowest cost, so the minister thinks that they should be allowed to attack tonight."

"You mean to let them go and harass the camp of Quangai Suwen?" Li Er frowned.

"Yes and no, we have more than 100 cadets, we can use most of the soldiers to harass, make them sleepless at night, and then divide two combat groups from this group of soldiers, lurking in the place where they store grain and grass in the rear, and when the battle is fought tomorrow, Quangai Suwen's troops must be pouring out, but they never thought that there was a strange army of ours in their rear, and when they fought head-on, they went to burn their grain and grass, and there was no grain and grass. Even if he has an army of a million, it is not a matter of concern, after all, people have to eat enough to fight, right? ”

After Zhang Nan finished speaking, Li Er patted his thigh and said, "Okay!" This method is good, Qingquan, I order you to order the cadets of the Qing Military Academy immediately, and I will personally send them out of the city. ”
