The MC can take over bodies of different people and essentially create clones. Once those clones are created, he can merge them into one, to create his own body.

For instance, the MC is one of the few survivors of a long destroyed clan. However, due to the special powers of the clan, he is able to utilize powers of another clan. Even at this stage, like 1200, the author/MC is confused as to which clan do they belong to. Not factually but rather emotionally. It really depends on the convenience of the plot.

However, the author suddenly did some Aizen level sh*t and destroyed the painfully slow reveal of the MC's past for the last 1000 chapters.

For instance, at one point the MC and two other entities are fight each other, a three-way fight. All of them are fighting against each other. In fact, one has betrayed another and yet, I can't seem to hate any of them. I know why they are doing it and in fact, what they are doing is probably MC like in their own mind.

he shows up in the other stories as 'the man with the black marks on his face' and yet in this story, the choice he made seems to make any showing up rather unlikely. Unless the man is a clone of SM the same way Slaughter is for Wang Lin? On another note, I do like the explanation for where the bead came from in Xian Ni, though it made me feel sorry for the bald crane.

so the MC was in a mountain training and a woman attacked him because he was occupying a mountain that had some sort of secret for two trides in that area after an intense fight with her he was hit with some sort of aphrodisiac and he tried to force down his urges it was good to that point but then..... suddenly out of nowhere they just introduce a new char that was sealed in the body of the MC and we never knew he even existed then suddenly a golden core appeared in his body and he became OP like hell and was able to kill anyone after raping women and sucking life force from mens heads ???? any way this was the main reason I dropped this novel it was just idiotic and I couldnt endure it anymore.

As soon as Su Ming leaves Dark Mountain, he just sits around in a cave until the plot forces him to go to the city, to sit down again at the kid's family, to sit at the inheritance cave, and so on and so forth until some character has to quite literally take over his body from his sitting position in a mountain and drag him to a fight with his enemy, just to later go back to sitting at the frozen island, the mountain again, the pocket realm and the pocket realm within the pocket realm, virtually missing every event in the place... a volcano, a meteorite, another planet... You get the idea.

Even in the ending the "dao of sitting down" is but reinforced. To finally be able to leave the world within Xuan Zang, the author makes us believe that Su Ming manages to comprehend his dao through his relations with others, but it is painfully clear the only reason he can transcend is that he knows by taking possession of Xuan Zang's body he can just sit down on a compass drifting in the void for millions of years without anyone bothering him, thus achieving the ultimate goal of his dao.
