In the past, some people in the Realm of Heaven speculated that the true immortals and demons were not extinct, they just stayed in a place no one knew.
Because no true immortals or demons appeared, and no one could find a real immortal or demon, speculations had always been speculations.
Now, Mo Xiu had several levels of certainty, that the speculation was correct. The true immortals and demons had not been extinct and would return to the Realm of Heaven one day.
In addition, the God Stele and Demon Stele were likely to be the means to control the immortals and demons of the Realm of Heaven.
Once the true immortals and demons returned, they could control the immortals and demons of the Realm of Heaven, so that the immortal and demons of today's domain could surrender obediently.
As for the "blessing of the ascending people of the lower realms", Mo Xiu didn't believe it very much.
