I would like to address how MC's powers work. Does he have certain time accumulate that he could use whenever and however he wants? Like, he have 60 years, so he could use 3 minutes to "go back" in time his body and still have like 60 years to use? Or does it work more like slots? Like, he have 6 slots that let him speed up or go back in time, with a limit of 10 years? So, he use one slot to advance his knowledge for the Dimensional Gate for 30 years, so now he have 3 slots to use. So he use them to go back in time his body 2 times. Leaving him with only 1 slot left. I ask because the MC said how he used the last chance to reverse his body to his normal state.
