Comments of chapter undefined of Physics The Greatest Magic

I feel like if it is a time travelling version of himself then Mors or the death spell would be a spell to accelerate the ageing of the human body or by stopping the cells in the human body thats my theory

every fight scenes here are confusing..the mc john is an anomaly but almost all the noteworthy fighters here seems to be below 20 so it kind of negates that point. they seem to be growing like cabbages in this world. the power levelling is still unclear and does not seem to apply to the fight scenes. i like the details of the fights but they kind of annoy and confuse the hell out of me. all of them at least have 3rd gears or super scian version 3s. 😅😓

Did John just get saved by a time traveling version of himself? If not, I got nothing lol. loved the chapter!
