He was once a pariah on the frontier. He was sacrificed as a living sacrifice because he strayed into the forbidden land of Jiuyuan. However, he swallowed the demon's blood and entered Nirvana, with the remnant soul of the ancient demon lord hidden in his body. He has a withdrawn and cold personality, hates being dominated, but sometimes goes crazy due to the backlash of his remnant soul. On the surface, he is a sacrifice, but in fact he is the demon king's body. He is the key to breaking Jiuyuan's rule and a living weapon for all forces to compete for.
