The internal space of Blood Dragon Cave is vast, with stone walls emitting a crimson glow, like the red dusk on the horizon, faintly dim yet fiery red.
In such an environment, it is difficult to assassinate or ambush.
What's even stranger is that the Source Power inside the Blood Dragon Cave is unusually dense and harmonious with humans.
Gao Xuan casually circulating Breathing Source Power could feel the Source Power nodes vibrating, seemingly ready to open new Source Power nodes at any moment.
However, the Source Power carries a strange and powerful spiritual disturbance.
This spiritual disturbance is extremely subtle, combined with the Source Power, and Gao Xuan, only through the Six-winged Celestial Cicada, could discern such anomalies in the Source Power.
Long-term exposure here would certainly affect one's mind, drastically altering their temperament.
