The sky above the Immortal Forbidden was enveloped in a crimson hue, as if the entire sky had been transformed into a sea of blood.
It was covered in fine cracks.
Amidst the crimson backdrop, the cracks appeared even more profound, and upon closer inspection, it became apparent that they were not naturally formed.
It seemed more like they were man-made.
They looked like runes covering the sky!
Just a glance shook the mind, triggering emotions of fear. One would be unable to control themselves, as though this was an instinctive act of life.
Hence, Xu Qing and the captain weren't the only ones who were shaken. At that moment, in the safe zone spanning over 1,000 kilometers in the Immortal Forbidden, all the human cultivators felt the same.
Great waves stirred in everyone's hearts as a sense of impending calamity suddenly rose.
