A simple problem, yet it required hundreds of years of training.

Wu Yu was now used to the pace of being an immortal.

If he could not devour, and could only rely on Great Sage Heaven's Equal's legacy, then perhaps it would’ve taken him several yuan's time to reach his current level.

Tackling one small problem at a time was complicated enough. A few hundred years, to anyone, was a short time.

It was also because he had devoured many immortals and ghostly immortals that he had inherited their way of thinking. Even though most ways of thinking were useless, a different angle of looking at the problem could still be of great help to Wu Yu.

Like a large number of immortals and ghostly immortals solving one problem together.

The Submerged Cloud Seal was precisely this, captured step by step. 

800 years passed in the blink of an eye!

Eight years passed outside in the meantime. The trial of the Great Void Immortal Path had just eleven years left.

Wu Yu was also able to remain, and continued training in the Floating Dreams Pagoda.

However, hard work always...
