"Little Lu, remember, if you see a flame with this kind of color, don't be afraid. With your Non-Phase Sword Bone, even if you resist it head on, you would not suffer a serious injury. But if the color of the flame is like this, you must be careful. You have to guard yourself from it using Non-Phase Sword Qi. No matter what, you must not let it touch your body, understand?"
On the training field, Sixth Elder Lu Li still maintained his amiable smile, but on his hand was a purple-black flame which was reflected on his face, making his smile more ferocious.
Wang Lu narrowed his eyes and observed the demon fire on Elder Lu Li's hand… It was a genuine demon race flame. From its breath, Wang Lu vaguely even associated it with that demon race inside the group of immortal tombs.
