Lin Feng, endowed with the Taiyin Physique, was capable of transforming his Spirit Essence into Taiyin Fire, which is one of the top-tier flames in the world.
It was also because Lin Feng's current cultivation was limited and he could not unleash the full power of the Taiyin Fire, otherwise, how could a mere Yin Energy Array withstand the scorching of the Taiyin Fire?
However, if he used the Yinyuan Bead to wield the Taiyin Fire, its power would undoubtedly increase manifold in an instant. By then, a mere Yin Energy Array would probably shatter in the blink of an eye!
Therefore, Qi Luyi was so excited upon seeing the Yinyuan Bead, and Lin Feng became so stirred up after realizing its significance to him!
Upon further consideration, although Lin Feng had Qi Luyi guiding his cultivation and had mastered many alchemy techniques, his actual combat ability was not strong.
