I am a bit lost. I am currently reading chapter 239 of the webnovel and I just read the part where the constellation killer gets revived from a ghoul and has his power restored. I understand that originally he was killed by mc but this was only one of 13 of his bodies and the second body immediately killed him which should reverse time so that all 13 original bodies are still alive. However now Gong-Ja has resurrected him fully as a person and restored his skills. Does this mean there are now two different versions of the 13 constellation killers existing simultaneously? Or did I miss something regarding the original constellation killer. I’m just very confused by how he was able to resurrect someone who is technically still alive.
