Three hundred years ago, he was the number one immortal in the world, holding the Cause and Effect Formation of Ten Thousand Lives, but he was framed and died; three hundred years later, he was resurrected as a tree, but he forgot everything.
Next to him is his old friend who became a demon for him and is called the King of Ghosts by the world - cold and paranoid, but he blocks thousands of resentful souls for him. Seven bloody injustices, thousands of years of grievances, humans, ghosts and ghosts are intertwined. Every investigation is a decision on the edge of life and death.
From strangers to trust, from resentment to side by side, from being protected to changing fate against the will of heaven... He and he spent three hundred years of waiting and sacrifice to rewrite the rules of heaven and light up the lights of all ghosts.
He is not just an old friend, he is the only person willing to accompany him through this heaven-defying journey.
All ghosts are chasing the lamp, love and karma will eventually fall into their hands.
