The overwhelming demonic aura surged forward, far surpassing any Hou Yuxiao had encountered before. The so-called demonic aura is the essence of demons, distinct from the blood qi of human martial artists. Not only does its intensity vary based on the demon's power, but it also changes greatly with each type of demon.
At this moment, in Hou Yuxiao's perception, there were at least hundreds of thousands, or even millions, of different demonic auras. The intensity of these auras was terrifyingly high, with the lowest being fourth rank, and the highest only second rank, yet there were at least tens of thousands, no, several tens of thousands of them.
Several tens of thousands of second-rank demons—equivalent to several tens of thousands of Sub-Saints of Martial Dao. A surge of shock roiled within Hou Yuxiao as his pupils contracted sharply upon seeing the outworldly scene; his face was aghast, just like the Sub-Saints of Martial Dao who emerged behind him.
