Liu (Musk) is a man that is reinacanated from modern earth, in an era of primitive beasts and humans competing to reign supreme. Due to chance, he embarks on cultivation and manages to reach the limit of strength in his current world, being forced to flee due to sense of crisis he feels getting closer the longer he stays. On his escape journey in space, he is swept by void tide into another dimension. Where he finds himself a new purpose and opponents on his rise to claim opportunity for eternity.

Musk indeed seemed more like a mortal when he appeared before others with his qi and blood restrained and Qi of power circulating around his body that seemed to fuse perfectly with his bones, muscles, and skin even stronger cultivators would not see a thing.
The bonus of his body having been baptized by the Heavenly Dew makes it even more difficult for someone with lower cultivation to tell a thing. It is also the reason even before Meng Hao he seemed more like a mortal. But in the end, he did not dare neglect, since he knew the meaning of the core disciple token, what he did not know was that around Musk's neck was the Heritage disciple Token.
The method was able to make Meng Hao believe he was a core disciple, and that was already enough for him. It was after all not his end game to show off his identity, rather he wanted some convenience and it seemed to have succeeded.
