Chapter 4 Black Flame Burning Heart

 Hongfeng smiled and slowly put his palm on Nie Xuan's back. Silks of black flames ran up Nie Xuan's body like black spiritual snakes. But strangely, these flames did not fire like Hongfeng. As he said, he entered Nie Xuan's body and started swimming on the surface of Nie Xuan's body.

 Nie Xuan felt a very strange burning heat suddenly come from his body. The reason why he said it was strange was that he clearly felt that there was scalding heat on his body, as if his skin was burnt, but from the bottom of his heart, he felt a burning sensation. There was an extremely strong sense of coldness.

 One cold and one hot, two completely different feelings, existed in Nie Xuan's body at the same time. This feeling was really uncomfortable.

 But this is just the beginning, because gradually you can see that many black lines slowly appear on Nie Xuan's neck, and these black lines seem to be alive, and they are still spreading towards the skin around Nie Xuan. Look, obviously this is the black flame that Hongfeng is talking about.

 At the beginning, the spread of Black Flame was not slow, but gradually it became faster and faster. In the end, it seemed to be running crazy on the surface of Nie Xuan's body, so that the area it covered became more and more. The bigger it got, and Nie Xuan's facial expression became more and more ferocious, because now Nie Xuan felt that the entire surface of his body was completely burning, and at the same time, the coldness he felt deep in his heart was getting stronger and stronger.

 Hongfeng stood in front of Nie Xuan and looked at Nie Xuan's face, which was also covered with black lines, with a satisfied smile on his face.

 Although Nie Xuan was feeling extremely painful now, he still gritted his teeth and persisted, operating the flow of spiritual energy in his body according to the Black Flame Level's martial arts formula.

 Nie Xuan didn't know that the flow of spiritual energy in his body was actually what caused the black flames to spread on his body.

 In just half an hour, these black flames had completely covered Nie Xuan's entire body. At this time, Nie Xuan felt, to put it more vividly, as if he was holding a piece of ten-thousand-year-old ice and sitting on a bear. Above the flames, extreme cold and extreme heat coexist.

 Now Nie Xuan finally understood what Hongfeng reminded him just now. This was more than just a little pain. It was a pain that penetrated deep into the bone marrow and even into the soul, because he could clearly see the Kui Niu and Kui Niu transformed by the heroic spirit. The force that had not yet fully formed was actually trembling slightly under this painful stimulation.

 However, at the same time, Nie Xuan could also feel that as the pain intensified, in fact, the area covered by the black flame on the surface of the body became larger and larger, and every muscle and every piece of his body Bones and every tendon are quietly undergoing transformation under this pain.

 At this moment, Zilong's voice came from Nie Xuan's mind: "Nie Xuan, what's wrong with you? What kind of breath is this? It's so strange!"

 It turned out that this kind of pain that penetrated into the soul had alarmed Zilong, but What made him most curious was that he couldn't tell what the aura was that was now all over Nie Xuan's body.

 Although the conversation with Zilong was all conducted through consciousness, Nie Xuan's voice from his consciousness was also trembling: "This should be the breath of the demon clan, the unique flame of the demon clan - Black Flame, help me strengthen it." Flesh."

 Zilong wondered again: "The aura of the demon clan? No, no, there is no way I can't distinguish the aura of the demon clan. Although it is very similar to the aura of the demon clan, it is definitely not!"

 Where is Nie Xuan now? Lili went to argue with Zilong about this issue. Seeing that Nie Xuan didn't speak, Zilong asked again: "I see you are in pain. Do you want me to help you?"

 Although he didn't know how Zilong could help him, Nie Xuan Rejecting Zilong's kindness, there was deep hatred in his voice: "No, I can bear this pain!" The

 motivation that supports Nie Xuan to endure this kind of pain now is the feeling in his heart that is deeper than the sea and deeper than the sky. High hatred!

 "Oh, in this case, I won't care about you, but I still have to remind you that this new friend of yours who doesn't know what he is, I think you should be careful about him. My feeling tells me that he is not a good person. thing!"

 There was a childlike immaturity in Zilong's words, and Nie Xuan did not take his reminder to heart, because Hongfeng helped him so much, how could it not be a good thing?

 Under the tremendous pain, Nie Xuan was still able to stay awake without fainting. So when the pain disappeared, he only felt indescribable comfort all over his body. Immortal, but he doesn't know yet that greater pain is waiting for him!

 At the same time, the black lines that slowly covered Nie Xuan's body surface, also known as black heat, retreated from his skin at an extremely fast speed and entered Nie Xuan's body like sea water at low tide. internal.

 Hong Feng, who had been keeping a close eye on Nie Xuan's situation, finally let out a long breath at this time and murmured to himself in a very low voice: "He finally got through the black flame covering stage smoothly, and It just took seven days, which is indeed very fast. I just don't know if Heiyan Burning Heart can survive it. If he can't survive it, then all my efforts will be in vain." Nie Xuan naturally saw it clearly

 . Seeing traces of burning black flames entering his body, he looked at these black flames with a little curiosity.

 He has seen natural flames and the flames generated in the bodies of cultivators after practicing, with various colors, but he has never seen such pure black flames. However, he didn't feel anything was wrong. After all, this was a flame unique to the demon clan, and his knowledge of the demon clan was almost zero.

 The trace of black flame seemed to have turned into a timid tadpole at this time, and it was a bit at a loss when it entered Nie Xuan's body, not knowing what to do further. However, as Nie Xuan used Hei Yan's formula to make them circulate in his body for several rounds, the courage of these Hei Yan gradually became bigger.

 With a "swish" sound, the black flames that had been gathered together exploded and turned into thousands of black flames, filling every corner of Nie Xuan's body. I felt a cold burning feeling in my heart.

 Suddenly, Nie Xuan, who had just been comfortable for a while, fell into great pain again. The pain on the surface of his body just now was compared with the feeling that every part, every corner, and even every cell in his body was burning now. , there is a huge difference.

 "Roar!"

 "Roar!"

 Nie Xuan's throat let out a heavy gasp uncontrollably, and his body began to tremble slightly from its original stillness.

 In the end, Nie Xuan could no longer stay awake in the pain that could no longer be described in words. After letting out an angry roar, he passed out.

 Seeing Nie Xuan, who had fallen into a deep coma, but whose body was still sitting cross-legged like a rock, the smile on Hongfeng's face disappeared and was replaced by a kind of anxiety. He reached out his hand several times. He came, but when he was about to touch Nie Xuan's body, he shrank back. Finally, he crossed his arms across his chest, ran to a distance and sat down, but his eyes were still fixed on Nie Xuan's body.

 The black flame in Nie Xuan's body was like a powerful invader. It successfully occupied every corner of his body and began to radiate its own heat to burn the body. However, this success did not last long. time.

 Hongfeng, who had been paying close attention to Nie Xuan's condition, had been keeping watch for nine days and nine nights without rest, and his face became increasingly ugly, because he could feel that Nie Xuan's life was disappearing bit by bit. It has reached the point where the oil is exhausted. In other words, Nie Xuan may die at any time.

 Finally Hongfeng couldn't sit still anymore, and Huo Ran stood up and murmured to himself: "If you don't take action, then he will die. If he dies, then my purpose of coming here will be in vain, but even now If Hei Yan is taken back, it will be difficult for him to wake up again! What should we do?"

 Just when Hongfeng was hesitating whether he should take action to suck back the black heat from Nie Xuan's body, his face suddenly showed surprise at first, and then a look of joy appeared on his face, because he clearly felt that he had been in a coma for nine days. A strong suction force came from Nie Xuan's body, and this suction force was unceremoniously absorbing the spiritual energy of heaven and earth contained in this purple spirit cave.

 Could it be that Nie Xuan woke up? Hongfeng hurriedly walked to Nie Xuan, observed carefully, and found that Nie Xuan was obviously still unconscious. How could he absorb the spiritual energy of heaven and earth? Could it be that his body absorbed it on its own? But it's impossible. Only after cultivating the Nascent Soul can a cultivator independently absorb spiritual energy through the Nascent Soul. However, Nie Xuan's cultivation level is comparable to his own, so he definitely has not cultivated the Nascent Soul. What's going on?

 But no matter what, since Nie Xuan's body can still absorb the spiritual energy of heaven and earth, it means that he will not die for the time being, so Hongfeng decided not to save him for the time being, but to wait and see what happens. Variety.

 Wave after wave of extremely rich spiritual energy from heaven and earth rushed into Nie Xuan's body one after another. They seemed to be running rampant in his body, but in fact they were shooting out traces of black flame from every corner in an extremely regular manner.

 I don't know whether it's because the amount of spiritual energy is increasing, or because Heiyan himself seems to be extremely jealous of these rich spiritual energy. Under the siege and interception of the spiritual energy, he has no power to fight back at all, and after a while, he has been infected by the force in his body. The middle part, and condensed together again, turned into a ball the size of a peach.

 At this time, both Ling Qi and Hei Yan stopped their actions, as if the battle between the two parties had reached some kind of stalemate.

 After a while, a small blue light spot suddenly appeared in Nie Xuan's brain, and slowly became brighter and larger, until it turned into a blue drop-shaped thing.

 The spiritual energy of heaven and earth in Nie Xuan's body seemed to know the appearance of the drop-shaped things, and actually took the initiative to make a gap for Hei Yan who was surrounded by them.

 Suddenly, the blue drop-shaped thing emitted a faint blue light, shining down from top to bottom, just passing through the gap.

 The light wrapped up Hei Yan, like fishing with a fishing net, and slowly pulled it upwards. In the end, the faint blue light completely integrated Hei Yan into the blue water droplets, making it A black flame that danced slightly appeared inside the water droplet.

 Immediately afterwards, the faint blue light emitted by this drop-shaped thing began to gradually weaken, gradually turning into a small blue light spot, until it completely disappeared.
