Tbh unless the use of the terms has changed in past year or two. Reincarnation is basically just either full reincarnation like reborn and everything, or soul inhabits new body. Normally body of someone who was already alive. Transmigration is normally used more for isekai like situations where a person body soul and all gets transported to a new world if I remember correctly.

This novel is peak Lu Shi dead *ss the goat icl. Or well ig the donkey.

Cool story so far, I am just a bit unclear on the fold increases. For example the 20 fold increase from 1st Stage to 2nd Stage Qi Gathering, does that make the total strength 20 fold, or 20 fold added to the original 10 fold making it 30 fold? Thanks for the chapter.
