In an instant, Shaoyu's hair turned completely white, but his aura soared several times over with the whitening of his hair, far surpassing Chang Qi in strength.
Lin Feng was astonished within his heart, Shaoyu's condition clearly indicated that he had used some powerful secret technique.
He himself had cultivated two secret techniques, the Nine Vortex Secret Technique and the Demon Shadow Clone. Both of these techniques were quite good, especially the Nine Vortex Secret Technique which had solidified the foundation of his formidable combat capabilities without any side effects. However, he had never cultivated the type of secret technique that could instantly boost one's combat power.
Such combat power-increasing secret techniques seem to always carry certain side effects. Lin Feng had encountered others who used such techniques before, like Xue Mo from Blood Luo Hall, who had used a secret technique to instantly boost his power with very obvious side effects.
