My Roommate and I Became Black and White

The world is changing, and the world is in chaos. Ye Xuan accidentally acquired the black impermanence inheritance, and Bei Xiaonan acquired the white impermanence inheritance. The two inspired the strongest impermanence system. Ye Xuan has a pair of yin and yang eyes, able to see through the sneakiness in the world, and cuts off ghosts with a black knife. Bei Xiaonan's "fascination" makes even ghosts ecstasy. As long as the world is peaceful, Ye Xuan takes Bei Xiaonan to see all the strange things in the world. Bei Xiaonan: "Brother, I also have a system. How about we work together?" King of Hell: "What the hell? You're even better than me?" Ghost King Xiuyan: "Don't stop me from causing harm to the world! Ah..." Ye Xuan: "Calm down, impermanence is here, keep us safe." This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
