Personally, I'd prefer if Tang Wei can be like the "grandpa in a ring" mentor trope of the genre. Imagine instead of the current state of Wu Heir needing to pick a side, we can just be independent and have TW actively teach us real cultivation to make our own destiny.
Maybe like a secret path that requires you to make certain decisions up to the expo and TW being interested to see how his perfect reincarnation would fare this time so he leaves behind a small part of his conciousness within us beside the Chaos Origin Physique and stuff.
It'd be much cooler than random dreams giving exp and ****
