The Cultivation World was indeed worthy of being one of the lower realms that had already surpassed the Mystic World. Just the foundation of the Heavenly Dao Academy, one of the nine Holy Lands of the Human World, had exceeded Qi Ming's imagination. It was actually related to the Upper World.
In other words…
Apart from the Heavenly Dao Academy, the other eight Holy Lands being able to rival the Heavenly Dao Academy were extremely likely to be the same as the Heavenly Dao Academy and could contact the Upper World.
Qi Ming circulated his cultivation method and Dharmic powers circulated throughout his body. He had already recovered from his injuries and did not continue deducing the history and future of the Heavenly Dao Academy.
If he really alarmed the experts of the Upper World, it would not be a good thing.
