Exorcists use their own blood to forge life-and-death contracts with demons, giving them a part of their bodies to inhabit. They are powerful, able to command demons with all kinds of abilities to fight for them. They are long-lived, immune to the ravages of time and forever young. But they must always guard against their demons turning on them, and endure loneliness to keep their fellow exorcists from coveting them. The young, handsome Ye Changge is one of them. Traveling the world alone under the alias “Old Man,” he has witnessed greed and desire, and known jealousy and hatred. Yet none of it can sever the bonds of fate or obscure the brilliance of human nature: loyalty, perseverance, love, and protection bloom gloriously in the demons. As the mysteries multiply, his old enemy Zhong Hu reappears, and the mysterious theft of the Liuli corpse makes it clear that a powerful force is pulling the strings. He has no choice but to head toward a battle whose outcome is uncertain... He has witnessed greed and desire, and known jealousy and hatred, but none of it can sever the bonds of fate or obscure the brilliance of human nature. He believes that only love can illuminate the darkness of human nature, like an endless night.
