He looks like he's related to you dude

He came from a hentai anime like u and he's probably the mc like u

did u go back in time so you can live a better life XD

Yes but who? 🤔

Maybe you are also his ancestor

sauce plz

The term "ancestor" in Asian culture doesn't necessarily mean a direct blood relationship. An Aunt or Uncle would count. This guy could die all the same, but as long as their are descendants of his family, he's an ancestor all the same.

well,, the "future" generation saved his life while asking that he must be succeed to make him live an easier life in the future, while he supposed to be dead... so I guess he didn't succeed at all... and the time line is going on

considering that nothing stand for a long time, even if he was a king this generation, it is very unsure that he would be able to leave anything to a guy from centuries or maybe a millenar in the future.
my guess is that if he succeed, he would make a bigger change in history, therefore it would require some timepolice to come investigate/correct the timeline. therefore there are less people chasing guy from future therefore making his life easier.
if he is indeed the descendant, making changes in the past should make changes in the future, if the timeline doesnt have a self correcting function, the possibility a same child is born is close to 0 dna wise (when the male cum, the probability its the same spermatozoid who get the jackpot is low) even if its the same parents (with major changes, the probability that that all the couples remain the same for all the time between past and future is close to 0 again).

either the timeline has huge self correcting capacities that nullify the changes, either it can make huge changes so that the couples doesnt change. for example if in original timeline mc escape and live his life as a farmer and marry a girl from the village, and in this time he becomes king, then that girl would need huge ammount of luck to become his wife to have a child who has more chance to have the same dna (need luck again from system). either this or there exist another combinasion of couples during the years so that guy from future can have the same dna. he saving mc this time means that he needs to be born as the same person.

on the other case, different timeline are similar to parrallele worlds, therefore he doesnt need to be fear disapearing coz changes in the past of another dimension. in this case mc cant make his life easier because he left more heritage but for another reason. my guess is as below, to use as bait for time police.

there's no such thing as paradox or time travel backwards because it will cause a loop. what we always do is sending a copy of ourselves in a parallel world, that's why we thought we are traveling back in time also that what happen is like this
