I Started by Taming Guan Yu, and Now I'm Terrifyingly Strong

Zhou Sheng transmigrates to the Three Kingdoms era and, from the start, discovers that he is on the verge of death. A burly, red-faced man is kneeling nearby. Just as he is about to die, he awakens the System.

Zhou Sheng is a wealthy landowner in Hedong. The county magistrate coveted his family's abundant stores of money and grain, but thanks to the Zhou family's generosity, Guan Yu rescues him.

Guan Yu recognizes me as his lord, and together we embark on the path to rule the land: crush the Yellow Turbans, pacify the Xiongnu, defeat Dong Zhuo, destroy Lü Bu, overcome Yuan Shao, suppress Cao Cao, drive out the foreign tribes on every frontier, and subdue the warlords of north and south. This is how a true man fulfills his ambitions.
