This is a slow, hot, non-YY book. After a hundred chapters, after entering the second volume, the protagonist encountered a special event and his personality greatly changed. He began to show the world his violent and bloody side! The Mortal level calamity gradually began to unfold in a hundred chapters. Countless terrifying natural disasters began to descend upon the Ghost Yard, the Winter House, the Terror Prison, the Undead Street Market, and so on. Nervous stimulation, berserk mode was a disaster!
