There is no special plot, so far there is only a boring harem and nothing else... And yes, he is very easy to control... all he needs is someone to sleep with him, and that's it...

I can understand that MC cares the most for his daughter... but MC is honestly nothing but trash... He and Tang San are the same type of double standard characters... The system is also low quality or good but the writer has made it useless by reducing the power... In short, the potential of the story was good but the failure of the writing has ruined it...

In my opinion, this story would be good to read just to waste time. I read over 100+ chapters, but the MC is still trash. What bigger fanfic failure could there be? Then, again, I'm reading fanfic here, not original. So, why is he making such slow progress?
