Review Detail of Kriti_Ttam in Supreme Harem God System

I have been reading it regularly as it is very good plotline with mc having cheat ability to power up through dual cultivation as he gets stronger not only he gets stronger his wife also gets stronger and he even gets their powers bloodline but recently I am having difficulty reading because mc progress has stopped with no improvement whatever and his wife are getting stronger on their own and he even stopped relying on his system which is I kinda support but he is still same sami peak Saint with no improvement and I am still skipping hoping to continue after he improve because all these matters that are happening can be done in few chapters but author is literally milking she is that , she is genius, she is this aaghh ooh dear author will you please focus on mc improvement now !!
