MC did not transmigrate twice. He has amnesia, a condition he inflicted onto himself. Also, he left himself warnings to not recover his memories as it is for the best. He eventually puts the matter aside as he believes in himself, but the past is uncovering itself.

MC is super powerful and feared by even those that care for him. He’s ambivalent because the future him is much colder than the current him. There’s a scene where MC panics about someone finding out he has amnesia. When talking to a fragment or something of his loss memories, it basically told him it doesn’t matter because no one should dare question him. This man is powerful and confident. Future him also basically revolutionized the world leading to being not only feared but respected creating this pressure on our MC.

Might be the ML. I’m guessing from tags. MC has only 1 disciple. MC seems to be involved with a ghost (was called a leftover of a strong obsession) and he might be the reincarnation. Idk. Anyway, his shadow definitely likes MC.

He was literally a servant but wants everyone to respect him. I would understand as equals but he wants to be treated by his peers like he’s better, and by century old masters like equals. Wild crazy. All because MC daughter told him he was talented. Like ??? She said talented not Jesus. I think he’s being set up to be a villain but he’s mostly annoying

MC considered that he adopted her because he’s always been gay in all his lives and forms, but dismissed the thought because they look very similar. He doesn’t understand why his future self was so cold to her. I think it was related to his cultivation method. He wants to make up for it but doesn’t know how to connect with her.

Apparently MC raised them. He took good care of them and was described to have loved children before he became cold. They wanna hold his hand. Lol.

in the secret realm they put aside their competitiveness and worked very well together to survive. The good nature of the sect stems from the leader again putting pressure on MC

- so at one point the MC's life (during the memory loss period) he goes around and starts collecting children to teach. One such child (Li... something I forgot) turns out to have died. I suspect that he's not actually dead or that he may have come back to life in some form, and that he's the lingering obsession that's more or less "haunting" the MC (this ain't my first rodeo in the genre, can you tell?) but we'll see.

- I have suspect a side CP.... which is backed up by an author's note.... but again I'm not that far into the novel yet so -

They met each other at their lowest, hardship only known to the two of them. But fate was cruel. It didn't sway for them. It was not for luck but for hard work they are able to meet again at their best. A chance to start anew, to love each other with all the best things they have. This is what they both deserves.

also they are good parents. Nothing s*upid like being jealous of the child.

He was around 24 YO programmer who seemed to transmigrate to his friend's stallion novel (or perhaps only the name of the sect is the same). But he transmigrated around 1000 years earlier. Rather than transmigrating, it seemed he was reincarnated into a baby born in that world and lived there for 16 years (my guess based on his monologue). Then he woke up one day and lost around 1000 years worth of memory. The gap is so big he feels like he transmigrated twice, but in fact he isn't. And he knows that.

ML is the reincarnation of the first batch of disciple of the sect. However he was also a lineage of royal family (possibly a direct prince), but at that time he was in difficult position and cannot stay in the capital (perhaps that's why he disguised himself and enter the sect). Past!MC and past!ML became very close and it seemed MC indulged and trusted him a lot. But, at that time, the royal family and the orthodox cultivation world were at odd with each other. It seemed Past!ML's position in royal family is actually high and as a result, he has to do something for the royal family (or perhaps for his position). He betrayed the sect and past!MC (if I'm not wrong he also killed a sect disciple that is precious to MC). So past!MC killed him with his own sword. Fortunately past!ML has found a complete set of reincarnation scroll/book (three of them) and managed to reincarnate safely into a human (unlike some other royals who used incomplete scroll and reincarnate into animal instead). Because he was a big villain, his reincarnated self was born with a demonic soul (his soul is demonic), has bad luck, and has a strange shadow following him everywhere (perhaps it's the form of karma?). He became a disciple of the sect, then became MC's direct disciple. Of couse the current ML didn't remember any of this.

I really like that the current time characters and the MC don't care about his current condition and don't bother to find out who he was in the past. MC with his memory might care a lot though, along with big villains that will show up in the story (because of the scroll, etc). As for now there is no explanation why ML reincarnate himself. But who wouldn't want to live again?

is not biological, but her birth bring some sort of trauma to the past!MC. I suspect she is the AI that MC create hence physical similarities.

When already-introduced characters enter the scene, the way it's written is like a new character. I was often confused why they were written mysteriously when the author should've made them obvious? Is it actually a new character??? But they're actually important side characters that the MC have met twice. Etc.

They have a troupe of MC of stallion novel such as tragic background story and golden finger (can be talent or artifact, etc) and they try to progress their life like a stallion protagonist (covet the sect leader's daughter, artefact, etc). It is as described in the description. But unlike in the description, the MC aren't aware of them (yet). These protag wannabe are canon fooder in reader eyes, but not worth mentioning in MC's world. It seems they'll appear one after another. So far, they are not transmigrator.
