Was there a novel that described the protagonist possessing another world, or something similar, where the protagonist had not betrayed his sister before transmigrating?

Find a novel's main character to possess another world.[Or maybe not, I forgot.] Before the main character transmigrated, he had betrayed his sister for a woman. Originally, he had some talent and was liked by his family. However, he gave all the good things to that woman. The woman liked someone stronger than him, so she found that person to kill the man, and then the main character possessed him.
The main character practiced some kind of martial arts. When he arrived in the other world, he felt that the martial arts in the other world were a little similar to what he practiced. However, the levels were a little different. There were 11 levels, and the protagonist even cured the brother of the person he possessed.

Answer 1

I recommend 'Fantasy: I'm really not a hot shot.' The main character becomes a servant disciple at the beginning, but he has the opportunity to steal the luck of others. The main character was not a hot shot, but he could plunder the luck of others. Thus, the days of harvesting leeks in the other world began. The protagonist betrayed his sister when he was underage, but he successfully counterattacked and became the protagonist through luck plunder. I hope you like this fairy's recommendation. Muah ~😗
