The effect was brief but incredibly powerful.
Seeing that Spiritual Perception was an SS-grade skill, Liu Yan was not surprised.
After all, it was a skill that could only be obtained after collecting all the fragments. Naturally, its level would be high.
Compared to Liu Yan's previous S-grade perception skill Omniscient Insight, Spiritual Perception was not only of a higher grade, reaching SS-grade, but it was also a passive skill.
This meant Liu Yan did not need to actively use it to benefit from the enhancement effect of the SS-grade passive skill, Spiritual Perception.
Moreover, when Liu Yan actively used his S-grade perception skill Omniscient Insight, the two skills could stack, providing him with an even more powerful perception ability.
At this moment, Liu Yan directly used his S-grade skill Omniscient Insight.
Immediately, Liu Yan's perception range expanded further.
He carefully sensed his surroundings and was quite surprised.
