Because someone who was dressed as Wuhan missed his hometown, he bought a big boat and planned to take his subordinates back to the Central Plains for development (and look for the blue Higanbana flowers by the way). As a result, he suddenly encountered a storm that only happened once in a hundred years. He recalled Wuhan's disdainful words in the original novel: "The people I killed were no different from those who were killed in a natural disaster."
The time traveler Wuhan: "... Damn it, is this retribution coming to me?"
After being rescued, a boatload of ghosts discovered that they had arrived in the ancient Central Plains.
The time traveler Wuhan said: "Forget it, it's okay if you don't die. It's just a matter of going back a few hundred years. It's trivial."
When he came back, he found that not only the people from the Demon Slayer Squad had followed him, but he also saw Enichi Tsukuni through his brother's eyes.
The time traveler Wumei: "... Did you see a ghost in broad daylight?"
