Transmigrate to the Tang Dynasty, Merge with Nanobots, and Become a God

The protagonist transmigrates to the Tang Dynasty, where his body merges with nanobots. He discovers what nanomachines can do and transforms the Tang Dynasty into a world of myth. Having read countless novels, I'm a veteran reader who's always wondered about the difference between the myths and cultivation in books and our real world. In the end, it seems there's just one thing: spiritual energy. If we could create spiritual energy, people in our world could cultivate just like they do in those books. This is a new writer's work, so please support me and share your feedback. Thank you.
