Furthermore, according to the female student's explanation, this also accounted for why once he entered Demonization's Realm, almost all his power vanished. If not for his other power upgrading to High-Dimensional Space-Time, he would have been unable to exert even a faint telekinesis!

When ordinary people dream, their consciousness is in the dream, so where is their real body?
Sleeping in bed in the real world!
