Build a Fairy Clan Starting from Daily Settlement

It looks strange. How did the protagonist know that the little brother needed 40 broken souls? According to the description of the little brother, it was impossible for him to care about what the protagonist wanted. Even when the protagonist gave it to him, he still asked for 20 broken spirits, but then he turned around and needed 40 broken spirits. And from the moment the other boy entered the Taoist Academy, he knew that the protagonist could not be saved, so this kind of thing was a common practice in the Taoist Academy. The protagonist had a better way out, so why did he have to keep that little bit of land and still offend others for nothing. This settlement cheat is just for getting access to various things. Now we only need a small amount of start-up capital to get it up. If we sell the land, we can get it. If we can't trust the Qian family, we can just find a reputable one. Why do we have to keep this poor land that can't be planted?
