Chapter 621: Fighting Hei Lou Lan

In the true inheritance secluded domain, all of the true inheritances had Giant Sun's will in them. Otherwise, how could all these fated individuals succeed in taking these inheritances, especially those Immortal Gu?

It was just like charging through rounds in Eighty-Eight True Yang Building.

In every one of the rounds that had Gu worms as rewards, these Gu worms were all refined by Giant Sun's will in advance.

When these Gu Masters succeed and obtain the Gu worms, they are able to refine these Gu worms instantly and keep them in their aperture because Giant Sun's will was purposely letting them have the Gu.

Because of this reason, as long as a Gu Master is willing to give his Gu worm away to someone else, they can always create a phenomenon of 'instant refinement'.

Earlier, when Giant Sun's will was slumbering, the refinement of wild Gu worms was extremely slow. When Fang Yuan first ventured into True Yang Building, he made use of this loophole.
