Shen Yan, the demon-slaying emperor who activates the "immortality" system, can cheat through krypton life. When he wakes up, he transforms into a ghost and kills Tanjiro Kamado! Only 13 years of life left at the beginning? Backhand overdraft for 10 years to unlock the "milk-scented knife"! Slaying ghosts and sucking blood to gain lifespan, teaching pillars to use stripes as mentors, the plot is more fragmented than a nightmare dream. "Don't panic, original novelist, I just changed BE into a life-changing novel!" Spider Mountain teases Sister Spider, Infinite Train's kryptonian life is on the line, there is a double kill in Flower Street and he also teaches the sound column how to fall in love... Muzan: How come Tanjiro can do a critical attack with a sword and still have resurrection armor? Shen Yan: 999 years of life can be wiped out with one sword. It only takes one second to swipe you.
