The mc seems to have a maturity of a 5 years old. There seems to be no back story as to why and how he has the system, if you are a lolicon, immature and have no sense of humor you may like this.
I followed this series for a year long, and it was... well, good enough, but now, after its abrupt end and the mc not even having a girlfriend it seems to have been a total waste of time. It had potencial and a great plot about ancient relics, girls, powerful families and this kind of fantastic system, but after the great competition there was no trace of the Manhua that it used to be.
i really liked this 1 and i would recommend but the end is soooooooooooooooooooo bad give it a read but dont expect a good fufilling end
