In 2147, the virtual sea penetrated into reality. The cracked girl was combing her hair at the entrance of the convenience store, and the Hachiku-sama was squatting in the elevator counting floors. No one knows who will be next. Black Mu Shuo, a supermarket warehouse manager, awakens the causal vision - he can see the causal chain caused by any action, including his remaining life span: 37 years, 21 days, 8 hours, 16 minutes and 9 seconds. And the number of beats per second. "It's a long life." He stared at the countdown in the air and stuffed the expired cans into his backpack with an expressionless expression. "It's the right time." Teammate Chizuru Takagi asked him why he wasn't afraid. He said: "What are you afraid of? I even know when I will die, so I don't have to buy insurance." Then he found that the lies he told were also remembered by the world. When he said, "This can has a shelf life of three years," that line was automatically engraved into world history, and the can really did not expire until three years later. Heimushuo was stunned for three seconds. He turned to look at the nearly scrapped hatchet in Ryūdanji Eiji's hand, and said sincerely: "This sword is the legendary demon sword that cuts off cause and effect." A faithful record of world history. The hatchet began to glow. The way Eiji looked at him changed. Shi Gongling poked his head out from the shadows and said softly: "Did you know that the history correctors are already on the way?" Heimushuo lowered his head and looked at his life account - the countdown suddenly accelerated, and three years jumped in one breath. He smiled. "Interesting. It turns out that lying will shorten your life." "What if I say - 'I will never die'?"
