Su Fan, the last meritorious hero guarding the abyss. He uses his life source to suppress the demon clan, uses his flesh and blood body to prevent eternal disasters, and prolongs the life of the human race for thousands of years. But what he got in exchange was not respect, but the crime of "colluding with the demons" and "killing his colleagues". Why bother to accuse someone? When his heart was dying, Su Fan angrily threw out the responsibility of guarding: "If we don't defend this city, we don't care about this abyss, and we don't protect this human race!" When he turned around decisively, Ling Xuzi and others who had coveted the opportunity in the abyss were so frightened that they knelt down on the spot - without his suppression, who can resist the demons in the abyss?
