Killing Immortals and Slaying Demons to Break Through the Sky

There is a gap between immortals and mortals. The nobility of immortals cannot be touched by mortals. How dare a mortal dare to become an immortal? A soul from another world was born in this world. His name is Li Haihan. He has no immortal roots and cannot cultivate immortality. His parents were killed by immortal cultivators for no reason. Since then, he has hated noble immortals. By chance, he obtained the purification system and embarked on the path of killing immortals and slaying demons.
