We Are in Spider Mountain, Starting with the Fusion Assassin Ah Qi!

Huo Yu, a time traveler who drifted from the end of the sea, came to the world before the plot of Demon Slayer: Kimetsu no Yaiba began. All the good things have not been broken, and the characters that have been killed by the plot are still there. Huo Yu, who had fused with Ah Qi, the strongest shadow assassin, raised the hands stained with the blood of countless people in Ah Qi's memory. He looked at them with another look and found that after the blood was washed away, these hands could rewrite all unfortunate fates... This novel and its characters are purely fictitious.
