I don't know about the others arc but considering the very first arc was terrible i don't want to read again. The MC was plain and bland i can't feels about his situation such joy, sad, or even scared. Even in the MC name in one chapter are different sometimes is Wang Bao, Wang Yang, Wang Ha, Wang Sang, etc. Like WTF the MC was not have a proper naming.
The plot was worse possible thing i read in this month. It feels like the author adding too many problems in the early of the story for the plot but not give a good god damn reason to solve it. Even when MC has to do something with the story it feels not rewarding at all for me.
The system was not bad but has very serious problem when come to the MATH. I think in early of the story author has drawing to many limit for him to be able handle it by it self. That why the solution he give for the story is only base on "It is what it is".
