If I recall correctly the MC finished his task and had to kill himself using the ML's body because his identity as the ML's heart demon would only hinder the ML and him from having his own body. The ML was forced to fall asleep when MC did that so he only knew that MC was gone after waking up but didn't know he killed him :' (and went crazy looking for him. When he came back hundreds of years passed even though it was less than an hour (?) of MC trying to buy everything he can from the system before he returns in a new body and that's what made the ML paranoid when reuniting with MC. But he gets healed by MC so it's all good

I did read the reviews under this title that complained about how draggy it was, how the plot doesn't make sense, or how the author added unnecessary suffering. I'm glad I disregarded the negatives (some of them clearly didn't read the story properly and provided misleading points) and went ahead to read it because the story isn't as bad as it's made out to be.

MC actually transmigrated twice. His first transmigration still led him to meet ML, but because of the system's assignment, he did not spend as much time with ML. Nevertheless, they still grew closer in relationship, only for ML to die in the end because of OG shou that had the old Heaven's Will backing. Distraught, MC killed the shou but since his soul suffered injuries, he went to recover briefly in a random small world and told the system that when the world resets, to assign him somewhere far away from ML so he doesn't get involve and die because of it.

However, the old Heaven's Will - in an effort to stop MC from returning - interfered with the timeline (causing the story that MC read before his 2nd transmigration to occur) as well as his character transition. MC was never meant to be ML's inner demon. In order to offset the consequences of this interference, the system provided MC with a sub-quest that, once achieved, would put him back on track onto the main task.

ML actually went through 3 lifetimes. First was with MC, but he died because of OG shou. Second time around, there was no MC by his side this time. He went through all the ups and downs alone, with memories of his first life, and followed along with whatever OG shou did to take back whatever luck that was taken from him by the old Heaven's Will. Third time, he has no memories of his previous lives and met inner demon MC for what seemed like the first time.

I get why there's a slowburn, but with both MC and ML having no memories, that's to be expected. Plus, after ML was forced to kill MC, he had to wait 300 years before finally meeting MC again (500 years short from Hua Cheng's own long wait in Heaven's Official Blessing). Is it surprising his spirit got shattered from all the sorrow, grief and anger that spanned those long years and eventually twisted his mind? Fortunately, MC managed to help put him back together in the end, and they had a few heart-to-heart talks.

I don't get what's so bad about the ending, like some had said. If it's for the fact that there was no epic battle between MC, ML and OG shou and main antagonist, or that the old Heaven's Will died too easily, do remember OG shou had already had 2 lifetimes of success and that previously, the old Heaven's Will expanded too much energy just to reset the world twice. If I were MC or ML, after being reborn one time too many with my enemies before me, I would kill them off post-haste, no fanfare needed. That's my opinion.

idk why but when Su Baimo couldn't remember what the lower realm looked like it really hit me. It's so sad because I feel like he's just pure evil but like if he survived he could've had such insane character development. I don't feel bad for him because it's the consequences of his own actions but when he said he couldn't even remember I was like f*ck that's so sad 😭 (maybe just me that feels that way idk)

I think it was so sweet how they slowly fell in love. It didn't feel forced. The MC also wasn't Gary Stu like not everyone fell in love with him.

I agree with one of the reviewers that he had potential but he low-key pisses me off. In the sense that he has a superior bloodline and all that stuff but he seems so weak in the end like I feel he didn't even try. Like he's super powerful but MC didn't even struggle that hard for him to die.

And then we get close to the ending and have a giant 300 year time skip? It felt so rushed! I think it could have been good if she had fleshed out the “new” ML. But the ML after 300 years was a total stranger compared to his younger self. The young version who was too nervous to touch the MC after realizing his feelings was so different to the ML who wanted to lock up and SA the MC (and I guess it was the 200 y.o. Broken spiritual fragment vs the 300 y.o.)

Since MC is an inner demon he needs to be killed by ML at one point, he eventually possesses ML or something like that and kills himself that makes the ML super emo after a 300 year period of separation !!! That to the MC was just a half a day due to the evil heavenly law. The rest of the story is just MC healing ML’s heart and killing the demon lord.
