Our straight (?) bottom woke up ten years into the future and found himself on the bed of his childhood friend… At the start, the bottom was shocked to his very bones, but he soon quickly accepted this premise and found the whole situation to be rather amusing. Precisely then, the bottom once again went back to his timeline — back to when he and the top were just platonic childhood friends.

Xiang Ye, who was working overtime and died suddenly, woke up and found that he had turned into an acre of land.

Just when he was at a loss, several big men carried a female corpse and buried it under him.

The accidental corpse dumping case made him uneasy, but then something even more shocking happened. The female corpse buried deep in the ground came to life on a certain moon hiding in the clouds at night…

“I don’t want to be a paradise, I want to be the most ferocious and most evil in this world.”

PS: It is probably the story of an acre of wasteland becoming a fine.
