From the Start, an S-Rank Horror Tale: I Only Have One Block?

(Comedy, plot twists, wild imagination and logic, mild horror, and smart protagonists and antagonists) My name is Shen Mo. It sounds cool, but things went horribly from the start: no memories, no teammates, and a block… But! What do you mean, you can jump from dozens of stories up and land in water? What do you mean, you can blow up eerie scenes with TNT? What do you mean, you can beat Cthulhu senseless with the Sword of Cosmic Dominion? Oh, right. One more thing you should know: this is a world gone mad, where the eerie devour people and vengeful spirits run rampant.
