Of course it is Cao Cao.

In fact, if you want to be friends, Liu Bei is the best choice.

Because he is broad-minded, generous, visionary, capable, generous, and sincere in his treatment of others. Truly the best person to be friends with. But the problem is that he is too unlucky. Before the Battle of Chibi, it was basically a "history of failures", going from one failure to another. Being his friend is too risky. If you are not careful, you may be captured or killed by the enemy, or you may even starve to death. I am a weak scholar and do not have the invincible martial arts of Guan Yu, Zhang Fei, and Zhao Yun, so I really don't dare to be friends with Liu Bei.

Sun Quan is cunning and cunning. He has no friends at all.

His only friend is himself. In his eyes, everyone is just a tool that can be used. If it loses its use value, it will be abandoned or even eradicated at any time. Many civil servants and generals in Soochow died suddenly and inexplicably. It’s actually worth pondering. In his early years, Sun Quan pretended to be a polite and virtuous corporal. In his later years, after his power was consolidated, he completely exposed his cruel and suspicious nature, and his indiscriminate killings and punishments were shocking. It’s better for us to stay away from such people.

Zhuge Liang is a perfect man through the ages, and being his friend will be very tiring. Zhuge Liang's moral sentiments and intellectual ability are beyond the reach of ordinary people. I am vulgar and kitsch, and I don’t want to restrict myself too much. Of course I am not worthy of being Zhuge Liang’s friend.

It is better to be Cao Cao’s friend.

Of course Cao Cao also had many shortcomings. He is also extremely suspicious. Fortunately, I don't have any ambitions, nor do I plan to rebel or anything, so I'm not afraid of his being suspicious. There are so many benefits to Cao Cao. The first is that it is safe to follow him. Cao Cao rarely lost a battle in his life. Always growing and developing. If you follow Cao Cao in troubled times, your chances of survival will be very high. The second is to have money to spend. Cao Cao was rich and generous. Always reward followers generously. Follow Cao Cao and you will have meat to eat. Third, Cao Cao is very enlightened. Cao Cao was a meritocracy and did not have high moral requirements for his subordinates. People who are greedy for money and lustful will not be discriminated against if they follow Cao Cao.

In short, if you travel to the Three Kingdoms, remember to make Cao Cao your friend.
