Reborn as a Crane?

In the chapter of the Immortal Cultivation World, the protagonist's teacher and friend Tian Xuan arrives. No one from the demon clan has disappeared. Then Tian Yu arrives at the end of the Cultivation World. When the chapter is about to end, no one can escape. The system that begins to appear is mentioned later. I thought there was no system. I wanted to return to the earth at first, but it was only in the last chapter that I started to crazily want to return to the earth. The dark forces in it are like Xiao Qiang who can never be defeated in the early, middle and late stages. The protagonist also mentioned it many times in order to strengthen the strength of the Cultivation World to fight against the dark forces, but the dark forces still took advantage of it. Therefore, there is no difference between strengthening and not strengthening. Every time the boss fights, the opposing boss must be stronger than the protagonist. The protagonist must fight with his companions. I feel that the protagonist, the demon emperor, is nothing. In the later life memories, there is no Tianxuan, but there is Tianjian Sect. Tianyu does not appear in it. In the plot, it is said that the friends have died of old age. These two are considered important characters. However, a fox pops up among the old and dead friends. In the previous plot, he was mentioned as the protagonist's right-hand man, but the two important ones were not mentioned. A lot of the plots in my memories don't match up with the plots I read earlier. If you want to read this novel, you'd better run away first. It's simple, easy to understand, and complicated.
