In my last life, I awakened the power of immortality during a global change. But he was framed and betrayed by his best friend, and imprisoned and experimented on by the human base. After suffering so much inhuman torture, I just couldn't bear it and chose to destroy my own soul to gain relief. But I was reborn, one month before the end of the world. This time I must make everyone who humiliated me pay the price.
