That judgment was absolutely reasonable.
Judging by the swamp's current setup, its strange poisonous miasma was still manageable. Ordinary immortals probably could not withstand it, but Yan Qianlie believed his current cultivation could hold up. The biggest problem was that flight was restricted above the poisonous swamp, leaving people no choice but to wade across. That was why cultivators had suffered devastating losses over the years, unable to fly over it.
Of course, the immortals were no fools. They had long since made numerous attempts to move mountains and fill it with earth, but everything dissolved on contact. Within the swamp gas lurked something like an intangible fire, burning everything away. Filling it was simply impossible. Only a very few exceptionally powerful artifacts could withstand it, but how many such things were there?
Yet the bones faintly bobbing in the poisonous swamp proved that bones, of all things, could float on its surface without even decaying.
Yan Qianlie had not understood why such a strange phenomenon occurred before, but now he had begun to form an idea.

This was also the "law" that the exposed stone slab sought to express. The purpose of that mystic art was to serve as a key, a prerequisite for entering the Secret Grounds-not to actually teach people how to assemble an undead army...

He acted immediately, ordering everyone present to gather anything that could be used to fill the swamp,
