I haven't seen the all chapter maybe only 10 but system is unique and amazing but why do you have to be so nationalism why add Chinese in it. It ruins the plot like han people are slave and now he will defeat north Korea empire and then again do the same as north Korea had done kill the royal family and make people slave what's the different anyway.It would have been better of you had Mc from earth goes to immortal world and use scab system rather than adding some bul*hit plot of Chinese killing north Korean ( I don't support north korea) .It remove all uniqueness of it and make it show f****** Chinese greatness(***₹&₹^&)
