Malachai, the undead apprentice, is trapped in the quagmire of despair. The dependent sister Lina's life fire is getting weaker and weaker due to the erosion of the strange disease. Only the legendary power of the soul can maintain it. Between his master's cold rejection and his sister's dying breath, he took a desperate risk and stole the taboo secret weapon "The Soul-Eating Skull". This evil object made from the skull of a powerful necromancer, every time it is thrown, it is accompanied by the wail of the dead soul and the scream of eternal torture by the original owner of the skull. When Lina's condition took a turn for the worse, Malakai was forced into a desperate situation and used the Soul-Eating Skull to destroy the ancient ossuary that suppressed all souls. In an instant, the imprisoned resentful spirit turned into a wave of souls that destroyed everything and swept through the huge crematorium. The tide of souls receded, and among the bones in the ruins, a strange new skull whispering dark secrets quietly condensed to summon spirits. Malakai holds the key to this more terrifying power, but he doesn't know that his sister Lina's fragile soul has been swept into the abyss of eternal destruction by the soul wave he released personally. This is a dark journey that begins with salvation but slides toward destruction. The balance of power and cost is swaying in the endless soul fire.
