According to the Fixed Star Compass's ability to sense Alien Star Evils, it can detect them even from a distance.
The detection of the Calamity-level Star Evil attacking Yanhe City was the best proof.
Thus, it was marked by the Fixed Star Compass.
"It really is an Alien Star Evil! No wonder it has such terrifying healing abilities," Liou Yuan scanned the information of the Alien Star Evil deeply.
This also explains why the Calamity-level Star Evil was so difficult to deal with, forcing Yin Yufu and that Foundation Establishment Sword Cultivator to retreat step by step.
Liou Yuan even suspected that Tang Hua's Soul came to Qingyou Prefecture for this Alien Star Evil.
"Tang Hua's Soul's cultivation technique is very strange; it can conjure the shape of demons out of thin air and use secret techniques to manipulate Star Evils."
