Comments of chapter undefined of How to Raise Your Regressor

Arteria: What did you do to me? Samur: Pfff, nothing of much importances. I just made you a immortal who no age no dies by super high regeneration and infinity mana supply, thus making you the most supreme being of the whole continant. Don´t forget you sneakers when you out, you aren´t yourself when you hungry

Thanks for the chapter

Shouldn't Samur's body have become stronger because of the new heart like Arteria? Maybe this is a plot hole...
