Possessed by the God of War in Three Kingdoms

The protagonist is a loser, a time traveler, who studies history, and has a system. He is already a champion. He saw the woman he liked being exiled and showed no sign of it. He finally met again for the second time, but he was obedient and did not express his feelings. He let Ren Hongchang disappear. He did not know that Ren Hongchang was Diao Chan. Then he sat back and watched Ren Hongchang being taken away by Wang Yun and given away. Liu Xie only used a book. The so-called Kung Fu that the character has no use at all allows the protagonist to feel at ease and become the dog of the Liu family. Apart from a shabby Kung Fu book and the so-called sworn homage, Liu Hong did not give the protagonist any benefits. Those rewards such as champions are due to the protagonist's military exploits, and they are deserved. In the end, the protagonist conquered the world and gave all the territory to Liu Xie. It is really rubbish. You deserve to be thrown into the street. The low rating is not unreasonable.
