As Lin Xing gradually left the range of the Spirit Cave, the concentration of demonic aura and spiritual energy around him also stabilized.
And in this stable state, his perception of the demonic aura became increasingly sharp.
If it had been the Lin Xing of the past, he might have been unaware of the subtle changes in the demonic aura.
But at this moment, after the period of cultivation he had undergone, Lin Xing's sensitivity to the demonic aura was sharpening more and more.
Within his perceptual range, his consciousness could feel the demonic aura in the entire environment was rising.
Although the increase was extremely slow, it was indeed steadily growing.
Upon hearing Lin Xing's remarks, the Sword Master and Bai Yiyi also felt a wave of surprise.
Only to hear the Sword Master say, "Is the Immortal Court still releasing demonic aura? That's not impossible... after all, it wouldn't be their first time doing this."
