Moreover, the intervals each time are different, so it requires some luck.
However, the Zoroastrian Sect people will observe near the Ruins beforehand, and every time the Ruins open, the clouds within will pour out. At that time, the whole area will be filled with rolling clouds, displaying very distinct features, hence the followers of the Zoroastrian Sect can then attempt to enter the Ruins.
Inside the Ruins, it is said that it is not void but rather a very expansive place.
According to Liu Futong, the Ruins are the origin of the Kunlun Dragon Vein, hence inside exists a Yin-Yang vortex that devours all surrounding Gang Qi.
Even the Gang Qi within living organisms cannot escape its devourment, which is the reason why no Gang Qi can escape the Ruins.
This is also one of the reasons why the Ruins suppress the Gang Qi within martial artists.
Understanding this, Chen Jiusi realized that the Ruins are the source of the gray fog.
