Note that this handsome guy is called Liu Dou. He travels through the Three Kingdoms with the most powerful blood cow system. He has a life span of 10,000 years at the beginning, and can convert his life span into health points. No matter how serious the injury is, he can consume his health points to recover directly.
However, before Liu Dou could study and understand his system, a few bandits cut off his life span of 9999 years. From then on, Liu Dou vowed to be a counselor and stay away from the battlefield.
So Liu Dou was reminded by the system and had to find a lord nearby. Unexpectedly, he was so lucky that he directly found the Tiangong General Zhang Jiao and became the chief military advisor of the Yellow Turban Army...
There is a system but it is so useless
