Soon, the Heaven God King went back to seclusion to continue his cultivation.
Since he couldn't enter the Netherworld to take advantage of its immense time dilation for cultivation, his only option was to use every available moment to train in the Spirit World.
At this time, a sense of urgency arose within him.
He knew that Lin Yun had already taken some of his spirit subordinates to cultivate in the Netherworld, even breaking through to the Divine Domain Realm.
He was also aware that the current High Level Layered Heaven in the Netherworld had a maximum time dilation difference of ten million times compared to the Spirit World.
If he did not cultivate diligently in the Spirit World, he feared that, given more time, those subordinates Lin Yun took to the Netherworld would surpass him in strength. By then, it wouldn't look good for him, once the king of the Innate Divine Race and a mighty being within the top echelons of the Divine Domain Realm.
