Record of Martyrdom and Conquering Demons

A man who is destined to die and a ghost who died on the battlefield before he reached adulthood are on the "destined" path, but they vow to rewrite the ending of the world that has been written. He acts as a hero, punishes evil and does good, but he also encounters the dangers of people's hearts for the first time during the journey, and experiences both warmth and coldness. Under the fate of a playful coincidence, a piece of history from the old world slowly emerges, and the boundaries between right and wrong gradually blur. Ask Heaven, who should decide whether it is a saint or a devil?
