Wu Xian's Black and White Era

He created human civilization, but now he is being hunted by humans. He is a legendary god in the human world, but he is also the "immortal eye" that everyone can kill. He once had the power of a god and could destroy cities with a single movement of his hands, but now he had to learn martial arts to defend himself. He is immortal and never kills. He has seen all the suffering in the world, but is still willing to give up everything for his friends. His name is Wu Xian, and this black and white continent belongs to his era.
