The premise is already stupid. Do you even realize how long it would take to practice for billions of times? How long is one training? Take for example that it would takes 5 minutes to complete one set of training, to even do that set of training 1 billion of times it would take 9.5 thousands years, and that is only for 1 billion, when it says billionS. This is also considering you don't do anything and just train without food, sleep, interacting, no pause at all, etc...Even if he gets faster as he does it continously it would still take THOUSANDS of years. This is almost as stupid as those check in novels."CoNgraTULaTiON! yOu cHeCkED IN fOr x100000 strEnGTh PoiNtS!" Can't we get actual serious novels that have a plot instead of these wishing fulfillment jokes? We didn't have an actual good novel for months, I bet half of these novel are just gonna get translated for some months before being dropped too.
