oh god you're making me confused too :''> it's not that complicated really
Dojin was chosen to be the emperor cuz the Yellow Dragon needs life force, so that's why he was sent to the past
About the dream, the first one was cuz YD created that dream, like the world, Dojin's niece and sister were not real, just a created world so that Dojin can be sent there and be safe(?) (can't remember why did YD create that place cuz it's been so long ago )
The second dream was also the same, but this time the YD in the dream world was somehow changed into the black snake, which is sent by the red lotus. One thing does make me confuse is that the black snake claimed he would trap the YD once he severed Dojin and YD relationship, then he would reclaim the god's position. Like IDK if this the red lotus's sayings or the black snake's. Cuz if I remember correctly, YD was a black snake when he first born, and then was stripped into yellow by the first time Dojin was summoned. So it does make me wonder: Does YD had a split sides? Like a black and yellow ones ? Heck Idk if there are any other readers out there who can answer this question of mine, that would be great :))
Anyway, about Dojin seeing himself as an old man, he was having a nightmare because of the poison from YD. Each times dojin gives YD life force (through abczx :') , YD would takes it and releases poison to Dojin. Don't ask me why, cuz he had a bunch of poison inside of him and he needs to let it out :'>
YD used his powers to rewind time 27 times. There were some timelines, where Dojin survived and went back to his world, but forgot all about YD, married a woman and lived happily. There were timelines where he was murdered, either by poison or being stabbed. And the timeline you were asking about was that he remembered everything, but couldn't find a way back to YD's world and died of old age, remembering YD. The most recent timeline was that Dojin was raped by the red hair dude and had a big trauma of it.
The tournament is called Hongrim contest, is like a battle between the guardians of each kingdoms to test their strengths and expand their hunting grounds. And the YD hadn't competed for a long time cuz he was too strong, thus upset the other kingdoms, so he held back.
And about tortoise's lover, we still don't know why she disappeared and the red-hair guy appeared instead, but I also think because YD messed up the timelines too much.
Dojin died in the human world he lives in and was summoned by YD to be the emperor from his world..to make it short they fall in love with each other but YD have a lots of enemy so they killed dojin many times before but since YD have the ability to turn back time he keeps saving dojin that is when you see him keep coming back from human world it was actually some kind of dimension to keep him alive so he have alot of memory from his previous deaths and because of that it also messed up the time thats why black tortoise lost his empress when dojin came back from death the situation changes the empress didnt came back but instead it was the guy now his emperor so he was blaming YD for what happen..and i think the last emperor was YD brother i wasnt really sure thou that is why he doesnt participated in the tournament i think that was the time his brother died..he want to participate this time coz if he wins he can bring back dojin from the human world and because he keep saving dojin from death hes getting weak himself i think he was dying so he want to bring him back..i hope my explanation will help..im actually a little confused myself
Ok oh.... actually it help some still confused about some things.... but you guys made clear some other points......THANKS! ε=ε=(ノ≧∇≦)ノ
Ok so I still dont understand this story..... I'm so confused ..... like can someone explain it to me and sorry but can it be from the beginning cuz I'm really stupid(￣∇￣")...... like I know that the uke became the emperor of this world .... and if I'm not wrong then that world is the past like he was taken from his "future" and brought to the past so he could become the emperor and save that place..... I dont know why though why was he brought there...... and I know he is YD lover dont know why but it's fine cuz they are cute af....... never understood the parts where he went back to his world again ..... something about it being a dream but like he was trapped at one point and YD was dying ???? Or something but then the dream broke and he got back but then he went back to dream world and came back again...... still dont understand that and why did he see him self as an old man...... is that his true self? And he's actually an old man laying in bed somewhere "remembering" YD.......and then he came back again and now the tournament like it's a battle for who's dragon can be offical leader to all??? And YD hasn't participated in a long time cuz the previous emperor died or something like that........ and now the tortoise lover died because YD messed with the timeline to much??? What?? Like what does he mean..... how did he mess with the timeline so much??? Is this world not a new one??? Is it just the past of our "world"?........ I'm sorry for the long post...... can someone explain this to me ╥﹏╥
