Reincarnation of the Heavens

In this world, there is a mysterious "reincarnation system". According to legend, after the death of every powerful person, his soul will be transferred to the system for infinite reincarnation. They will be thrown into one different world after another, experiencing various identities, fates and tests until they can break through reincarnation and become true "immortals". But this system is not perfect. Some souls acquire memories and abilities from previous lives during the reincarnation process, break the rules of the system, and become "reincarnation retrogrades." They intend to control the power of reincarnation and change the destiny of the world. This novel and its characters are purely fictitious.
