Great improvement in art of alchemy

There was no Celestial King standing by at the valley entrance.

There were wide implications involved in this journey through the Mystery Realm, and there were a good number of descendants of even Eighth heaven Celestial King that had entered into this space, such as Yan Xianlu. Thus, not one Celestial King had come here, all seeming to be certain their own heirs would have enough ability to protect themselves.

That was the truth as well. Every single monarch tier and emperor tier had a life-saving secret technique bestowed by a Celestial King. Unfortunately, they had encountered a maniac called Ji Wuming. They did not even manage to use such techniques, and had simply died directly.

This was also a test from the Celestial Kings for their heirs. Ordinarily speaking, seeing as every single one of them had the backing of a Celestial King, even if they were no match for their opponent, it was extremely rare for anyone to deal a fatal blow.
