Xuanling Tianshuang

This world is the only independent world in the universe, and it is called the "Xuanling World". Everyone here has an ability, which can be said to be magic, or more accurately, "mysterious spiritual power". The "mysterious spiritual power" is only discovered at the age of six, and the innate "mysterious spiritual power" determines whether a person can become a "spiritual master" in the future! This is the most respected profession in the world, to which every resident aspires. One day, a boy from another world was born here with a hanging chain and memories from his previous life. He is a demon king from another world and a terrifying god of death. He was young but stood at the pinnacle of his previous life. He once saved the entire world alone, but he became the world's public enemy. He watched helplessly as his lover was being killed but was helpless. He didn't expect that the hanging chain he got by chance would change his life...
