alrighty, it has been over a year that i read it, so i don't remember all details, but
(spoiler alert)
so after some big shit goes down in china where he helps, he is allowed to keep the wasted land there. he then proceeds to train his leagues of shadow soldiers and the new shadow soldiers from the original sovereign that came to him previously with that guys awesome as shit leader dude who will fit in awesomely with igris etc. (dunno if they alread came maybe) anyway. so he trains with them and divides them into groups with the leaders he has. and then some stuff happen and the other sovereigns get serious, a lot of huge battles and it seems like they are winning somehow, because he planned really well with his 3 or 4 groups of leagues. the last battle is then on is land with the leader of those sovereign and they fight insaley fierce. but it seems like no matter what he does, that sovereign guy keeps having something up his sleeve and he is loosing....suddenly the angels come down. they help him and he asks them to allow him to use their time travel device once more (i think it only had one use left or something anyway) because he wanted to avoid the world falling apart like it did...because he now knows who the enemy is and how to beat them....and he will not loose his shadow soldiers, only the ones he made new i think like the ant ( i am not sure though).....the angel is shocked, because they say how no one will know about anything he sacrificed if he is the only one that remembers in the whole world. but he still does it...than we see him suddenly in a totally normal korea at university, everyone is talking about this mysterious mature famous student ( obv. him)....he just came back from checking on people i think like the old guild leader who obv. is alive now and no one ever knows about this whole dungeon stuff, because he made it so they never came to be as he send back into the past, but still had his memories and his powers....and he is now just a normal student at uni and dating that short hair famous girl properly.....that's it....i was so bummed, because it all happened with time slip you know...suddenly the battle was interrupted, he was send back and we were in the present....the author didn't show what he did or anything...anyway.....yeah...hope this made sense...( i even forgot the names as you can see has been so long really haha, but the novel is translated in english if i am not wrong and was really nice to read, if you don't want to wait for the webtoon and read it)

OMYGAWDDDD SERIOUSLY THANKYOU FOR TAKING YOUR TIME FOR WRITING THIS AND WTFFFF WHY THEY DISAPPOINT US LIKE DAT BRUHHHH I WANTED HIM TO DEFEAT EVERYONE AND BE THE WORLD'S BEST SS RANK HUNTER AND THEN MARRY MS. CHA WHO ALSO IS A BADASS HUNTER AND THEN PROCEED TO LIVE IN A WORLD WITH MONSTERS AS USUAL DUJHNCIDNSHU BRUH THIS IS SAD LMAOOOO

ohh you mean before he goes back in time or after?
(possible spoiler alert)
cause as far as i saw on tiktok, the dad is already there before he went to the past....i don't remember it all 100%, but i cannot remember if the family situation was shown after he went back...only that he was dating that super stron female hunter (who was obviously a normal woman in the non wrecked past) and that that hunter guild boss guy was now a politician or what and he was just looking around like some 100 year old vampire in the body of a kid at those young clueless happy goofy students like a proud parent hahahah....that is what i felt from the vibe from the text....he is a lil arrogant after all :D and yeah....he is the only one who remembers, as well as his shadow soldiers (who the author did not show in the epilogue) and the world is just normal. he seemed happy...dating that cha girl now as normal teens in college and having everyone alive and healthy etc...

but again (spoiler alert!)
if they did not show his dad yet....he will come....he is found in a super old ass dungeon where he was stuck and survived and became a super strong ass hunter guy....he does some stuff to help his son behind the scenes and he finds him during a battle where he was not super bad ass death sovereign yet (his heart and the sovereigns heart were not totes in sync) i think....and the dad died there after that battle, while trying to run from his son so he would not see....i hope i remember it correctly though.....but after he went back in time....everyone should be alive and living normal, cause the dad never went to become a hunter and never went into a dungeron where he got stuck etc. ....
that for the first time, i already know the whole content of a super hyped famous webtoon ahahah....i am looking forward to reading this when it is finally complete to see what the artist did with the light novel.....i hope they will also do something special about the end, cause the end in the novel was like super "bland" in comparison to the whole awesomeness of the story....
