Immortal Cloud Aura

On the mountain path, Chen Fei surveyed his surroundings.

Compared to the Primordial Sword Sect, there wasn't much difference, but as time passed, a subtle change appeared in Chen Fei's expression, and a hint of astonishment flickered in his eyes.

The spiritual energy, the density of spiritual energy around him, was gradually rising. Although the increase wasn't yet significant, it was clear that the Immortal Cloud Sword Sect had established a formidable formation that was influencing the fluctuations of spiritual energy.

Only this way could such changes in spiritual energy density occur relative to the outside world.

Moreover, the deeper he ventured, the more apparent the rise in spiritual energy density became.
