Li Lingtian had refined the Wutian Palace and completed the construction of the Divine Kingdom.
Driving the Brahma Heavenly Palace back, he originally wanted to leave some of the people in the Brahma Heavenly Palace to train in the Brahma World. However, when he thought of the demonic beasts and divine beasts in the Brahma World, he gave up on this idea.
In the Brahma World, not to mention Divine Lords and Godly Kings, even Divine Lords and Godly Venerables could die at any time.
The divine beasts and demonic beasts here were all Divine Masters and above. The most powerful ones were even Divine Beasts at the Paragon God Realm. If they encountered such divine beasts, all the people in the Brahma Heavenly Palace would die.
In other words, the Brahma World wasn't suitable for experts below the Divine Master level to train in.
