Rebirth of the Three Kingdoms: Brother, I Don't Want to Fight for Hegemony

Kong Xuan was reborn in the Three Kingdoms. When he opened his eyes, he was besieged by the Yellow Turban. He wanted to compete with Boss Cao and Liu Da'er, but Guan Yu and Zhang Fei appeared on the scene. They killed a group of monsters with one swing of their swords and killed them with a spear. Only then did he realize that he was as fragile as a porcelain doll. Rebirth does not come with its own system, nor does it have the ability to turn stone into gold. It cannot even make glass or cement. Wanting to compete for hegemony is just a pipe dream! Stay alive! Living is the way to go! At any rate, our family still has knowledge that transcends this era for two thousand years, so it is not difficult to survive! Unexpectedly, he managed to survive and became the biggest Persian! No system + slow heating + farming
