[Not a romance! Not a romance! Not a romance! I don't know why there's a romance tag. By the time I noticed, the tags couldn't be changed.]
High schooler Jiang Yuyu was young when he followed the trend and transmigrated.
After happily gaming and falling asleep over the weekend, he was jolted awake by a middle-aged man. He immediately slapped the man, who flew into a rage and frantically spanked him.
It was the first time in his life anyone other than his parents had spanked him. He was furious, and then he got over it.
He had transmigrated into the body of a twelve-year-old elementary schooler? And this kid was especially mischievous? No System, golden finger, or missions to help him transmigrate?
Whatever. The elementary schooler, Xu Baique, was his golden finger: a genius at cultivating spirit beings.
Xu Baique worked hard at cultivation, while Jiang Yuyu enjoyed a lie-flat life as his abilities rose in tandem.
Jiang Yuyu transmigrated into Xu Baique's body and was mistaken for a ghost. He laughed awkwardly. “Hey, buddy. Mind if I stay in your body for a while?”
Years later, Jiang Yuyu had a new body and met Xu Baique again.
After a few drinks, Xu Baique said, “Jiang Yuyu, I’ve liked you for a long time.”
Jiang Yuyu: “...Buddy, I really think of you as my little brother.”
While investigating a case, they saw a gruesome scene. Xu Baique said, “Big bro, don’t be scared. I’ll protect you.”
Jiang Yuyu thought, “No... seriously, is something wrong with you?”
After the case was solved, Jiang Yuyu willingly set off with Xu Baique to roam the world.
It's okay.
