At the command, Immortal Sect disciples who had been assigned the task summoned wind and clouds. In moments, the winds surged and moisture gathered, forming thick dark clouds that pressed down over the formation.
The weather had been poor to begin with. Now the sunlight was blocked out entirely.
The hundreds of thousands of Ghost Soldiers were numerous, and the Yin Energy they gathered could shield them from sunlight for a short time. But doing so drained their strength every moment; they could not sustain it for long.
Fortunately, the various sects had countless Dao Arts that could solve this problem and let ghosts roam in daylight.
Concealing them beneath dark clouds was undoubtedly the cheapest, least demanding Method.
The army marched with black clouds overhead and dense fog rolling around it. There was not a trace of an immortal host's splendor; instead, it had an eerie, ghostly air.
That was hardly surprising. Even Immortal Sect disciples dealt more often with Ghost Gods unless they entered the Yang Spirit Realm and transformed their Dharma Power into Pure Yang.
Apart from Yang Spirit True Persons, only a few elite Yin God True Persons like Tang Changsheng could directly affect the material world.
With such a display of power, the formation advanced dozens upon dozens of miles into the Wilds without encountering the slightest trouble.
But the road grew harder and harder. Jagged mountains rose everywhere, steep beyond measure. It was as the saying went: not three feet of level ground.
Nor had anyone ever set foot in a place like this. There was not even the faintest path. Ordinary people would have found it nearly impossible to take a step.
But most of these Immortal Sect disciples were Yin God True Persons, with only a few at the Illusory Spirit stage.
