The Heavenly Demon King now lives more cautiously and carefully, because one day he suddenly discovered, he was not the strongest in this world, he was not omnipotent!
In the past, he always thought the heavens and the earth were the largest, and only the Celestial Beast King and Jake King could stand on equal footing with him.
But later he suddenly realized that the world was constantly changing, everything was evolving, not to mention others, even that Gabriel Freeman, he couldn't beat him.
Moreover, he confirmed from the intelligence he gathered from various sources that there were ancient monsters in this world, and there might even be Immortal beings!
So he began living very cautiously and returned to one of his secret sanctuaries from the past.
