It's not a retreat system, it's simply a cage. It would be good if he retreats silently and manipulate the world behind the scenes, but the MC is so high profile that other use him for a scheme and he can't fight back unless the enemy enter MC retreat world because the system will shut down if he left the retreat

It's not bad, but the ending is boring

This is a unique novel, it's cultivation novel but the cultivation system is relying on dao fruits left by the strong man in the past. The dao fruits system is similar with beyonder system in Lord of the mystery, dao fruits have 9 levels and it's own characteristics that need acting to fully consume the dao fruits. The first 100 chapter was good, but after that the story really mixed up, the author more concerned about number of words rather than the quality, so he just put plot after plot without any break in the middle, so I feel tired just by reading this novel. It's by no means that this novel is bad, it's just that some plot is so forced in order to achieve certain number of words. Plus there's forbidden romance between MC and his teacher, it's so unnecessary and disgusting
