Review Detail of Sheyon in My Beautiful Disciples, I'm really not the Main Character!

The story was great, the premises also great. There really isn't much problem in the novel. At first i was expecting someone who tranmigrated or reincarnated and acceepting heroine as a disciples (without reading the synopsis and only intrested on the title) but, i didn't expected him to has a choise system and the system it self felt okay. The only thing i didn't like so far is MC was said to be walking conqueror(?) path. Until the latest chapter i read (around 70+) it was more like the bluffing path. All of the option he chooses only gave him item that make him temporarily strong. There was not really an option with a reward that gave him strength of his own. He was even scamming his sect master disciple and make her his student by deceiving her. the said student is even more powerful than him, so what is it if it was not just him bluffing. It was not i don't like the MC but, what i don't like is how the system reward work. The choice system gave is great and intresting the only problen is the reward. It looks like he will only start getting stronger until he use the fragment memory. What i didn't understand is why he didn't try to get stronger by trying to cultivate.
