Yang Qingyun's idea was excellent,
but unfortunately, reality always left people disappointed.
After spending most of the day searching, he had practically scoured more than half of the Grotto-heaven Secret Realm.
There were quite a few resources inside as well.
Heaven-and-earth treasures such as Dragon Blood Grass and Dragon Blood Fruit, which had once been hard to find in the outside world, were not exactly everywhere in this Grotto-heaven Secret Realm, but they were at least not rare.
There were even powerful demonic beasts roaming certain places, each carrying a trace of Flood Dragon bloodline.
But unfortunately,
this Heaven and Earth Secret Realm had been an unimaginably enormous opportunity for Yang Qingyun before he reached the Supreme Realm.
But to him now, it was nothing much.
The resources required for the path beyond the Supreme Realm were simply too vast!
He had scoured the entire Heaven and Earth Secret Realm for resources and refined them,
and although they could bring him some improvement,
that was all they could do.
He was still a considerable distance away from breaking through the second stage.
After all, accumulating magical power after reaching the Supreme Realm was not something that could be improved so easily.
The greatest opportunity and most precious treasure within the entire Heaven and Earth Secret Realm
was most likely the Dragon Soul Essence formed after countless unknown years by the ten thousand li Flood Dragon mountain range submerged beneath the sea outside the Grotto-heaven Secret Realm.
It had already been refined and absorbed by Xiao Tianshu,
allowing him to ascend to the heavens in a single step.
This made Yang Qingyun frown slightly.
Could it be that he had come all this way for nothing?
No!
What Xiao Tianshu had taken was the benefit most easily extracted from the outside.
