Yes

Ugh...yeah I know I pretty much gave a far simpler version of what you are saying last chapter, without the more exact specifications just to leave things more vague just so that my guess can be more correct due to the author having the degree of freedom to change small nuances to the overall story and the rest of that information is already shown in the story as well. This guess was just an extra possible conjuncture to that due to Xi Longyi showing hints of slightly deeper/different feelings towards Jiang Daoyi at the end despite what he did due to circumstances and feels more interesting to me. Though I do admit I appreciate the explanation given to my comment that seemed ignoran to this information, so thanks.

Is the soul that the current Xi Taianyi devoured from birth the soul of this timelines Xi Longyi also sent to the past like Lei Jingye and that’s why he feels some sort of connection to Jiang Daoyi?

Similarly from a spirit increase by meditation, spirit increases from items doesn’t increase mana? Either way good chapter.

I’m guessing that the current Lei Jingye is his future self sent to the past from this timeline ( or something similar) but this time Xi Longyi was taken over by Xi Tianyi, hence why he knew his name of Xi.

Diggy diggy hole? I know where that’s from...
