In the long wait of a month for the letter to be delivered, Li Er had already formulated a detailed battle plan with the generals of the Tang Dynasty, and even Li Jing, who had been staying in the military academy, and Qin Qiong, who had been retired at home, were called by Li Er to discuss countermeasures.

Within a month, Li Er and his generals kept summing up lessons and lessons from the previous wars against Goguryeo, and rushed to produce a large number of weapons such as kamikaze crossbows and thunderbolts, and finally formulated a set of combat plans that Li Er thought could be called "perfect".

But he didn't expect that King Rongliu of Goguryeo would agree after receiving the letter, and he would actually agree.

It's like you finally fell in love with a girl and wanted to chase her from the beginning, after you have thought about all the ways to chase her, the first thing she said when she saw you was that it was a thousand dollars for a night.

It's so embarrassing, it's so uncomfortable.

"Ladies and gentlemen, what do you think about this?" Li Shuangshou was holding a letter of state given to him by King Rongliu, which was clearly written that Goguryeo recognized itself as a vassal state of the Tang Dynasty and was willing to take out the prisoners proposed by the Tang Dynasty to provide infrastructure assistance to the Tang Dynasty.

"Your Majesty, the minister thinks that since our purpose is to take prisoners, and now Goguryeo is willing to give them prisoners, then even if our requirements are met, I am afraid that it is not appropriate to send troops, and our soldiers of the Tang Dynasty are more expensive than his Goguryeo people, so the minister thinks it is better to forget it." Li Jing stroked his beard and said.

Li Jing is of course talking about the group of military cadets under him, although Li Jing has always had high standards and strict requirements for them, but if he really wants to throw this group of professionally trained people on the battlefield, Li Jing is really a little reluctant.

Therefore, Li Jing advocated not fighting.

"I said Wei Guogong, you are retired, and you have fought enough in this life, so enjoy the blessings of Qingfu, I haven't played enough in Lao Cheng, so you can't give this opportunity to us young people?" Cheng Yanjin said with a grin.

"Fart, you're still young, you really don't want to be faceless, you Cheng Zhijie has rough skin and thick meat, naturally it's not worth a few dollars, the cadets in my military academy, all of them are treasures, if you go to the battlefield and are injured by those Goguryeo people, the old man will be distressed." Li Jing glanced at Cheng Jin and said.

"Yes, yes, your old cadets are all treasures, so don't let the cadets of the military academy go this time?" Cheng Biting Jin also sneered at each other.

"Okay, Uncle Bao, tell me what you think." Li Er rubbed his temples, closed his eyes and said, the current Li Ertou is very big, originally I wanted to take Goguryeo to sacrifice the flag, but now it's okay, the armor is half worn, and I want Li Ersheng to take it off.

"Your Majesty, the minister also thought that this could not be fought or try not to fight, although our Tang Dynasty is strong, but after all, fighting a war is something that hurts the peace of the heavens, Qingquan had a theory at that time and the minister still agreed, that is, the war must be fought purposefully, and it is necessary to make it clear what kind of result to achieve after the war. Now that we have reached the result, I think that this war is unnecessary. Qin Qiong also said neither humbly nor arrogantly.

After more than ten years of fighting, although the war brought Qin Qiong high-ranking officials and prestige and honor, he was used to seeing life and death, and Qin Qiong still hated war in his heart, no matter which side he was on.

"Well, Qingquan, what do you mean?" Li Er handed over the topic to Zhang Nan at this time, although Zhang Nan played the role of a mascot most of the time when discussing the matter against Goguryeo in this month, but now on the issue of whether to fight or not, Li Er still wants to hear Zhang Nan's opinion.

"The minister doesn't have any ideas, there are benefits to war, and there are benefits to not fighting, but the minister thinks this thing is a bit strange." Zhang Nan said with a frown.

There is no reason, it can be said that the regimes of Goguryeo and the Central Plains, whether it is the Sui Dynasty or the Tang Dynasty, belong to the state of a mortal enemy, and there is no reason to directly agree to the request.

And those requirements or wording are almost all dictated by Zhang Nan himself, it can be said that the rhetoric is very intense, as long as he is a backbone and bloody person, Zhang Nan feels that no one will agree.

But it is very strange that as the emperor of Goguryeo, King Rongliu agreed, and he agreed without any conditions, which made Zhang Nan uncomfortable and quite surprised.

"Yes, I also think this thing is a little strange, this is not the Goguryeo we see on a daily basis. I thought they wouldn't agree no matter what, but why did they just agree to our request now? Li Er continued to rub his temples and said.

"Could it be that they saw that although I made it a real conspiracy, but it was cracked like this, I was really a little unhappy." Li Er frowned.

"The minister guessed that there must have been a visionary in this Goguryeo who was pointing out, or maybe this reply was written by that person." Li Jing stroked his beard and said.

was reminded by Li Jing like this, Zhang Nan really remembered something. But the reason why Zhang Nan remembered it was because of a TV series.

Later generations of sticks made a so-called "historical drama", of course, a historical drama written by themselves. The name is "Quangai Suwen", in this drama, this Quangai Suwen is not only the real power controller of the entire Goguryeo, but also shot one of Comrade Li Er's eyes blind when Comrade Li Er attacked Goguryeo, turning Comrade Li Er into a one-eyed dragon.

Zhang Nan was able to remember this drama because he had seen the illustration of Li Er being shot into a one-eyed dragon on the forum, and by the way, Zhang Nan also sighed that the original official history can be fabricated.

Thinking of this, Zhang Nan silently searched for information about this Quan Gai Suwen in the system, I don't know if I don't check it, after checking, Zhang Nan really feels that from the standpoint of the Goguryeo people, this Quan Gai Suwen is really a fucking talent.

In terms of experience alone, the experience of this Quan Gai Suwen is not insignificant.

First of all, he was born, Quangai Suwen was born in a nobleman, and his father was the great counterpart of Goguryeo, that is, the prime minister of Goguryeo, after his father died, he successfully took over his father's position and took charge of the military and political power of Goguryeo.

The second is his upper experience, if it is written into a book, Zhang Nan feels that this book will definitely be popular.

When King Rongliu ascended the throne, he and his henchmen planned to get rid of some powerful generals in Goguryeo, and prepared to be the first to take out the most threatening to his throne.

After Quangai Suwen learned of King Rongliu's plan, he directly set up a Hongmen banquet for King Rongliu and his ministers, and after killing King Rongliu's hundred ministers at the banquet, he broke into the palace to kill King Rongliu and divide his body.
