After handling matters in the Eastern Domain, Chen Yu returned to the Great Yu Alliance and began his secluded cultivation.
According to the information obtained by Chen Yu, the primary world is the oldest and most extensive realm in the vast universe, the source point of everything, the origin of all things.
No one probably knows how many years the primary world has undergone.
Even a great realm like the Great Yu Realm is just one of the many realms under the control of the Human Race and Demon Race in the primary world.
In the Great Yu Realm, the pinnacle of cultivation is the Xuanming Realm.
The known Emperors of the Xuanming Realm within the Great Yu Realm can be counted on two hands.
But the primary world is different; there are Gods, who are almost omnipotent, with powers to reach the heavens and earth.
For example, the "Food God," who once appeared in the Eastern Domain of the Great Yu Realm, came from the primary world.
