Illusion techniques are different, they can silently infiltrate the opponent's Sea of Soul and gradually change the opponent's cognitive bias during battle.
In the struggle between the two, such cognitive bias essentially amounts to a fatal flaw. If Ye Feng had only cultivated spiritual power, he perhaps would have found it quite difficult to grasp such flaws.
But the issue is, Ye Feng also cultivated the "Thunderbolt Divine Body," known for its aggressive attacks and speed. With just the slightest flaw in the enemy, he could quickly seize it and deliver the most ferocious attack.
Of course, illusion techniques are even harder to master than direct attacks with spiritual power, so what Ye Feng is doing now is just a simple attempt, without too much expectation.
However, judging from the current situation, Ye Feng feels the effect is not too bad, at least against these ordinary Mutated Animals.
