At the turning point of the Three Kingdoms and the battle of Guandu, who helped Cao Cao establish hegemony, but died worthless?

The battle of Guandu in the Three Kingdoms period was very important to Cao Cao. It can be said that this war was a turning point of that era. After Cao Cao won the war, he quickly annexed four states in Hebei, and became the world overlord from a small warlord, which laid a good foundation for Wei to establish a unified world. At that time, Cao Cao won the battle of Guandu, and the first credit minister was not Cao Cao's counselor or general.

But it was such a person who, with his own strategy and accurate judgment, helped Cao Cao analyze the situation at that time and let Cao Cao seize a strategy to turn the situation around in one fell swoop, but his ending was tragic. This person is Xu You. He was very clever when he was a child. People in his hometown thought that he would become a character when he grew up. As an adult, he was recommended to be an official in Beijing, where he met young Cao Cao and Yuan Shao. Later, I followed Yuan Shao.

Xu You also became the chief strategist of Lombardi Group, ranking above ten thousand people under one person. At that time, Yuan Shao provoked the battle of Guandu with great strength. At that time, Cao Cao's army was only 50 thousand, and the other side had 200 thousand, and there were many good equipment. Just when Cao Cao questioned whether he could win. Cao Cao was very happy to learn the news of Xu You's mutiny.

Because Cao Cao knew that he might make a comeback, Xu You brought Yuan Shao's war plan and troop deployment, as well as the distribution place of military supplies. Under the discussion of everyone, Cao Cao decided to break through the enemy grain depot in one fell swoop and then defeat the enemy. Then there was no food, the enemy's army had no resistance and soon surrendered. Cao Cao also defeated Yuan Shao, and Yuan Shao died soon. Although Xu You made great contributions, Cao Cao looked at such an arrogant man. I was so angry that I found an excuse to kill him.
