I remember these points from the novel: Female MC Empress mother Once in their lifetime, people in MC's family fall unconscious while their soul reincarnates in another world. MC ends up in modern Earth. After waking up, she forgets everything that happened before transmigration and thinks Earth was her original world. Xianxia type world - but with the ruling family's soul journey, technologies from other worlds are available. MC goes to a sect as a new member/student to find something from their forbidden grounds. MC's long term goal is to build a computer Any idea which novel this is from?
Only ever read the blurb, but seems like it might fit: https://www.royalroad.com/fiction/33748/reverse-reincarnation
