Yan Yinwen looked at Chen Fei in some confusion. She sensed his aura fluctuating slightly, but a moment later, it returned to normal.
The cultivation levels of those in the Mountain Sea Realm could be judged by their auras, but this assessment was rather crude. At most, one could discern how many divine palaces they had.
Determining exactly how far the divine palaces within their bodies had developed was impossible.
In particular, Chen Fei's Purple Heaven Gang Sword had already reached the perfection realm, giving him considerable control over his own power. It was even less likely that anyone could discern the state of his third divine palace.
Thus, as far as Yan Yinwen could tell, Chen Fei's aura had merely fluctuated for a while.
As for the spiritual essence that had just been in Chen Fei's hand, there were many techniques in the Mountain Sea Realm for extracting spiritual essence, but the extracted essence also contained a great many impurities.
No Mountain Sea Realm cultivator would absorb spiritual essence directly. The gains would not make up for the losses.
Moreover, for the vast majority of Mountain Sea Realm cultivators, what prevented their cultivation from advancing was not a lack of energy, but insufficient comprehension of their cultivation methods. They could not control that much power.
Only heavenly materials and earthly treasures like the Sky Dew Flower, which could help them comprehend their cultivation methods while providing sufficient energy, were the best choice.

Since this altar produced monsters, and those top-tier sects were
