Previously, Liu Yan had also used his A-grade Omniscient Insight and SS-grade Extraordinary Five Senses to distinguish the strength of the Withered Tree Spirits' original bodies and their clones.
However, there were too many Withered Tree Spirits, and their original bodies suppressed their strength, making it difficult for Liu Yan to distinguish them. He could only distinguish them with extra effort. During a battle, it was impossible to distinguish them while fighting.
Liu Yan's current S-grade Illusionary Clone was much more powerful than the A-grade Clone Technique.
The principle was the same as before. The clone was also a form of elemental energy.
However, compared to the A-grade Clone Technique, the S-grade Illusionary Clone was undoubtedly much more powerful.
