Seizing Fate Through Nine Tribulations: From the Start, I Took Charge of the Reverse Scales Bureau

Creating an Inner World, From a Small World to a Great World, a Minor Thousandfold World, and Finally the Void

Looking for books like I, the Heavenly Dao, Build the Strongest World. The protagonist creates a world inside his body. It should be a System story with a vast setting, from small worlds all the way to the void. Ongoing and not yet completed.
