The Art of War says that if you know yourself and your enemy, you can fight a hundred battles without danger.
Therefore, as the commander-in-chief of a large army, it can be said that he spares no effort to find out whether the enemy is true or not. The spies and spies are almost omnipresent.
Even a city wall cannot withstand the contact between spies and spies and those they are loyal to.
Throughout the ages, various perfunctory tactics have emerged one after another to use spies to find out what is true and what is true, and to use tactics to give false information to enemy spies, thereby taking advantage of the enemy's army and annihilating it in one battle.[
Therefore, Cheng Yu concealed the good news about Yan Zhong's mission to Xianbei, just to prevent Liu Feng from hearing the truth and making a decision that would ruin the good thing.
Everything was just as Cheng Yu expected. Liu Feng had spies in the city, and there were quite a lot of them. At a fixed time every night, they would write information on cloth and drop it on the city wall.
Because nothing in the city could be concealed from Liu Feng's eyes that could penetrate the sky and the earth. Naturally, Liu Feng saw and heard the changes in the city's momentum.
On this day, late at night, the warm wind blew slowly, making people feel sleepy.
Outside the north city gate, in the central tent of the Han army's camp, Liu Feng was kneeling on the commander's seat wearing a cloak and only his underwear. He was holding a piece of cloth in his hand, which recorded the situation in the city.
It's warm today and makes people sleepy. Liu Feng has gone to bed long ago, but even if he goes to sleep, he can't ignore the changes in the situation.
After receiving the report from the minor official that something important had happened, Liu Feng immediately got up and read the news.
"The trapped beast Yudouer."
Liu Feng threw away the cloth and smiled coldly.
How could Liu Feng not understand Cheng Yu's intentions? He was probably expecting Yan Zhong to have arrived at Xianbei, so he released the news. He thought it was safe and he would have no chance to stop Yan Zhong.
This created this moment, an increase in morale, and an opportunity for the army to fight again. It can be said that everything Cheng Yu did was not wrong. Not only was it right, but it was also considered cautious and wise.
But Cheng Yu was still wrong. He was wrong because he didn't know. Liu Feng had long understood the weakness of the grassland. When Cheng Yu sent Yan Zhong as envoy to Xianbei, Liu Feng also sent Deng Zhi at the same time.
Sent an envoy to the Huns.
Yan Zhong endured humiliation in Xianbei and was finally able to seduce the Xianbei people. When he planned to participate in the battle to unify the world, Deng Zhi had already completed the task outstandingly, killing the Xiongnu Chanyu Yufuluo, and then integrated the Xiongnu
Human power launched a war against the Xianbei people.
It can be said that seizing the opportunity was enough to catch the Xianbei people off guard. Just this opportunity was enough to gain the upper hand in the early stages of the war despite the power gap between the Xiongnu and Xianbei.
Spend the Xianbei people's strength on the grassland.
It doesn't take long, a few months is enough. But there are 160,000 troops in Jinyang City, and 160,000 mouths, and they are all the mouths of strong men.
It's like a huge black hole, swallowing up food rations. Months, months. How much food can Cheng Yu, a senior official, have to support him?
Therefore, Liu Feng called it "a trapped beast still fighting."
The words are disdainful, the expression is disdainful, and the heart does not take it seriously.[
This matter is the responsibility of a junior official in the army, and at this moment, this junior official is standing in front of Liu Feng, with a respectful and extremely obedient look. This junior official is just mediocre, and he cannot understand Liu Feng's disdain at this moment.
