The runes on the Firerock were very ancient, at least ten thousand years old.
The history of its existence far exceeded the time the foreign martial artists had entered the divine Kingdom, so it probably had nothing to do with them.
Perhaps it was because the sky had been accidentally torn apart that this thing had fallen and landed in its current position.
&Nbsp; of course, there were other possibilities. Perhaps the outer realm martial artist had used this Firerock to attack the divine Kingdom's planar barrier, forcefully tearing open space.
Of course, all of this was not important to Tang Zhen.
The key was that these runes were of a very high level. Even in a high-energy world, runes of this level were rarely seen.
Such runes could only appear in higher level super planes. Everyone in those worlds could become gods, and they were incredibly powerful.
