Review Detail of MrVenerable in Obtaining 10x rewards! Reincarnated into a novel as a side-character!

I already read chapter 1 - 107 I am mostly cool at everything, except in the chapter when the MC fights the sister of FL. I find it annoying where the MC is basically showing his power and the powerful people are watching, and the MC pretends to lose because he fills pity on the female lead that she might lose her idol, who symbolizes the undefeated title. Guess what happened? Of course, the result of that stupid decision is a fucking consequence that 5% out of 100% would happen if the Mc were not making unreasonable decisions. Now, the elders will become wary of him since he is basically a strong competitor of the heirs of the strong clan, and yet he has achieved nothing. Why, man? Crazy world we lived in. Anyway, I'm really sorry about this review that I made. I'm just tired of reading about MC hiding their power for simple reasons, and I am not saying I don't understand it; I understand it, actually, but the weight of the benefits of showing your potential outweighs the weight of the consequences.
