Zuo Sheng Yi Lingjun

The nerd Lin Shu was persecuted and died. He accidentally merged with the remnant soul of the ancient demon god and walked around the world as a half-human and half-demon body. He met the down-and-out prince of Qiyuan Kingdom and helped him regain the throne. The ten years of hard work finally turned out to be full of calculations. Although he was extremely disappointed with the dynasty, he cared about the common people. In the end, he sacrificed his remaining humanity to become the demon god and slaughtered the entire demon god family, protecting the peace of the world he cherished for a hundred years. . .
