Chapter 675
Looking at the naturally formed Heaven-and-Earth Formation below, Lu Qing directly activated his spiritual power and began deducing and comprehending.
The reason he had told the white flood dragon and Xiaoli to leave the valley was precisely because he intended to use this formation, spanning a thousand miles, as preparation for his upcoming Nascent Soul Tribulation.
Originally, his plan was to find an even stronger Heaven-and-Earth Formation.
That way, he could also avoid destroying the white flood dragon’s dwelling place.
But now, with only ten days left to prepare, time was too tight. He could only make do with what was here.
He would have to modify this vast formation and turn it into a weapon for his tribulation.
With Lu Qing’s current mastery of formations, deducing a Heaven-and-Earth Formation was naturally not difficult.
It wasn’t long before he had already deduced the most suitable scheme for himself.
After working out the plan, Lu Qing descended back into the cave, summoned the Li Huo Cauldron, and took out large amounts of refining materials to begin forging the formation cores.
