The moment Jiang Liu entered the mist, he immediately sensed that it was strikingly similar to the mist emitted by the Moon Devouring Clan.
Back when he entered the Yellow Springs Mountains, the Moon Devouring Clan members had also carried this kind of mist on their bodies when they appeared.
Although he had no idea how that mist had come to cling to the bodies of those Moon Devouring Clan members.
Moreover, judging by their appearance, they should have been able to control the mist.
Even so, this made Jiang Liu certain that this place was definitely the passage between the Human Realm and the Nether Realm.
After all, the ancestors of those Moon Devouring Clan members should have emerged from this mist back then, before putting down roots in the Nether Realm.
The only problem was that he still did not know how to deal with this mist.
However, if his estimate was correct, there should be a formation here controlling the mist, preventing it from spreading outward.
It was precisely because of this mist that no one had discovered this passage all these years.
As for the people who disappeared after entering this place, that was probably also because of the formation.
"Hiss, hiss, hiss!" The mist and the primal qi within his body frantically canceled each other out.
The primal qi within his body was also being rapidly depleted.
Jiang Liu now understood why the guards who had charged into the mist had died.
Their primal qi had been completely depleted, after which the mist had corroded them.
As for the mine slaves, there was even less to say. The primal qi within their bodies had long since been sealed completely. They had no way to resist the mist's corrosion, so they had surely died beyond dead.
