Review Detail of Tha_Vault in I've Reincarnated And I'm OP!

This is bad, like really bad. Overpowered mc, has 5m in stats at lV1 while the average is like 20. God tells him no one in the world has this much stats but the have to hide your power.... yes!!! He’s possibly the strongest person in the world at level 1 and like 6yrs but he’s hiding his abilities .... why????!!! Because the author says so...... His entire family gates him because while hiding his stats he made it too low so thet all think is weak!!!!! Why does his damily hate him!!!!! Author says so.... His sister is getting maried or something but it looks like the family and the sister don’t really want to. So Mc says i know they gate me but its my sister so i have to save her (this is stupid but hold on this is not the stupid part) The mc says to the person that wants to marry his sister ‘’I challenge you to a duel for the hands of my sister’’ Yes thats what he did.
