Demon Slayer: My Hex System Is Killing People Like Crazy!

When the comatose Jiang Yan opened his eyes again, he was already in the mountains of the Taisho era. There is only a body named Grandpa, a dull knife that cannot kill ghosts, and a death wish to go to Tengxi Mountain. In this world where evil spirits are rampant and the breathing method shines, he did not inherit any gorgeous sword type, but awakened a [Hex System] that exchanged power for a price. [Future Vision II] allows him to see life and death within three seconds, at the cost of a heavy mental load. [Cursed Crown] gives him a cold edge against ghost attacks, at the cost of emotional blunting. [Devil Contract] Forces burning lifespan, which can instantly break through the realm and force the pattern to open/touch the transparent world or evolve the Sun Blade into the He Blade. ... From the first cry of Mount Fuji, to the flames of Mugen Train, to the end of Mugen City. Jiang Yan holds the unburned blade in his hand, uses Hex as his chess piece, and stubbornly searches for the path to survive and win among countless branches of the future. Even with every step forward, he was getting further away from "humanity". "Wuxian, let's see whether you are purified by the sun first, or I am swallowed up by my own price first." "As for the ending... I've seen it countless times in 'The Future'."
