This novel moves back and forth from present time to past a lot so yes there is a flashback (ch 30-44) of everyone back when they were all 15 yo. Juniors from all the prominent sects were sent to study in the Cloud Recesses for 3 months and that's where everyone met each other for the first time. i.e. where Lan zhan and Wei Ying met. A lot of stuff happens and everyone (Jiang Cheng, Jin ZiXuan, Jiang Yanli, Wei Ying, Lan Zhan etc) all go through a lot of shit together but especially wei ying and lan zhan. They have a real (rocky and non-romantic) relationship in the past. Then more stuff happens and Wei Ying dies then (13 yrs later i.e. current timeline) he is reincarnated into the body of Mo Xuanyu when Mo Xuanyu summons him with that ritual we see on page 1. Wei Ying (in his new body) immediately recognized Lan Zhan There'll b more flashbacks (like a lot actually fyi) anyway I hope that helped? If anything else didnt make sense I'll try to help out

Wei ying dies completely. He basically disappears off the face of the earth, countless sects and high level cultivators including lan zhan tried to summon him and nothing. In the novel, 13 yrs later mxy sacrifices his own body and soul to summon wy back into the world. (16 yrs later in Untamed, the live action)
I'm sl confused, was there a flashback at ch 30-50 or something?? and how does the current seme connect to the one in the past, was he reincarnated?? or did the MC die a few years before the times he's in right now in his new body?? how does the MC even know the seme "from before"??
