Why Did I Become a Bandit in Chang'an During the Three Kingdoms Period?

In the Three Kingdoms, I am the younger brother of the Guan Yu clan, and I am in charge of the stormy den of thieves. Make friends with Ma Chao and ride northwest. Holding the yellow on the left, holding the blue on the right, Brother Ma and I can come and go in Chang'an at will! Dong Zhuo, old dog, send Diao Chan to me! Use violence to control violence, and enjoy grudges and grudges.
