In March, in the depths of Baektu Mountain, there was a "boom" several times, and the birds and beasts flew away, all away from that place, and there was a thick black smoke rising from that place, like traces after being burned.

This is a clearing, a man-made clearing, surrounded by scorched trees, even the ground and mountain walls are scorched black, Murong Yinzhu stood there in white clothes, looking at the black aura remaining on his palm, and sighed lightly.

"The Black Auraist is really good." A clear voice came from behind him, it was Lin Chenqing, "I haven't seen you for a long time, you have practiced this flame palm to perfection, and if you continue, this mountain of Baitou Mountain will be burned by you." ”

Murong Yinzhu let the black spiritual energy on his palm dissipate, and turned to Lin Chenqing: "The spiritual power is not enough. ”

During this period of time, in this deep mountain, there was no one, Murong Yinzhu could only rely on the blood of various beasts to maintain his survival, except for a few extremely rare and rare beasts, the aura and vitality in the blood of ordinary beasts were far inferior to the blood of humans.

As for the taste, after drinking the blood of the living, sure enough, the other blood is very unpleasant.

The spiritual power couldn't keep up, and cultivating this flame palm every day required a lot of spiritual energy, which gave Murong Yinzhu a little headache. However, this is a quiet place, and a place that ordinary people can't find at all - at least Lin Rong didn't find it.

"It's already a small achievement." Lin Chenqing said softly, "It's just that why do you want to cultivate this Flame Palm that has been abandoned by the Murong family?" Moreover, Baitou Mountain is overcast and cold, and it is not a good place to cultivate the Flame Palm at all, to be honest, you can exert your power, which surprises me. ”

"My Flame Palm is not the same as the others." Murong Yinzhu shook his head and looked at his palm, "It's cold, without any temperature." ”

"Huh?" Lin Chenqing was stunned.

"It seems that the black aura can only melt into black flames." Murong Yinzhu stretched out a finger and slowly drew a simple formation in the air, during this time, she already knew some of the basic formations here, all of which Que Yun told her, "You try it." ”

She poked the formation, and a small black flame came out in the middle of the formation, looking like a fake, and floated in front of Lin Chenqing, Lin Chenqing stretched out his hand, lightly touched the black flame, and made a puzzled sound.

"Cold fire?" Lin Chenqing just touched it lightly and quickly retracted his hand, looking at his fingers, his nails were disappearing at a speed visible to the naked eye, fortunately, he still used a layer of protective aura, and the fingertips were not injured, "This is cold fire!" ”

"What's a cold fire?" Murong Yinzhu had never heard of this name.

"I've heard about it in the classics, but I didn't think about it, but now I remember when I touch this flame, this is a cold fire, unique to black aura." Lin Chenqing frowned, "There is no temperature, and you may even feel extremely cold when you are burned, but the power is very powerful, even if it can't be burned by an open flame, it can be burned." ”

"Hmm." Murong Yinzhu suddenly remembered that day in the Flame Cave, Murong De was so nervous about whether she wanted to learn from the Flame Palm, whether he also knew such a thing as cold fire, and didn't want Murong Yinzhu to use the Flame Palm to give full play to her advantages as a black aura.
