Unconsciously, Zhou Tianlong and Yu Feilin had been at the entrance of the underworld for ten days.

At this moment, Zhou Tianlong was still sitting cross-legged on the ground, his eyes were closed, and he held the seal of the Saint Martial Heavenly Dragon Jue in his hand, continuing to refine the flame, and the clothes on his whole body had been burned into nothingness by the intense heat on his body, and now he was naked.

In Zhou Tianlong's dantian, a golden dragon slowly circled. And in the encirclement of the golden dragon, it was the blue flame. At this moment, the blue flame that had been raging and destroyed Zhou Tianlong's body was like a domesticated beast, and it had long since lost its original wildness, but obediently stayed surrounded by the golden dragon, slowly burning, looking quiet and peaceful.

After nearly ten days of breaking through, the flame found that this golden dragon was extremely powerful, and no matter how hard it could, it was unable to break through its encirclement. So now, that flame has also given up resistance, and chooses to stay obediently in the golden dragon's body.

And as the golden dragon continued to squeeze, the volume of this flame became smaller and smaller. When Zhou Tianlong first swallowed it into his abdomen, it was more than three inches long, and later after being catalyzed by the wind attribute true qi in Zhou Tianlong's body, it became several feet long. But now, it's less than an inch long. Although the length has been shortened a lot, the fire attribute energy contained in it is increasing day by day.

At this moment, Yu Feilin was standing behind Zhou Tianlong, staring at Zhou Tianlong's body with a pair of beautiful eyes. At the beginning, she faced Zhou Tianlong naked, and she felt very shy, and she didn't dare to look at Zhou Tianlong's body, especially the place on Zhou Tianlong's body. Although she had already inadvertently seen that place once last time, she still didn't dare to look at it because she was shy. But she didn't dare to return, but Yu Feilin's heart was very curious, after all, that was the biggest difference between Zhou Tianlong's body and her own body, so sometimes, she also forcibly held back her shyness and secretly glanced at it.

Ten days passed, and Yu Feilin gradually got used to it. Now, in the face of the naked Zhou Tianlong, she is no longer as shy as she was ten days ago, but has become a lot more generous. But even so, every time she inadvertently swept to that place on Zhou Tianlong's body, she would feel that her heart was beating very hard, and her face was flushed and extremely hot.

Now Yu Feilin is also very worried about Zhou Tianlong's safety, after all, ten days have passed, and Zhou Tianlong has been sitting there without moving. If it weren't for Yu Feilin who had tried his breathing, I was afraid that she would really doubt whether Zhou Tianlong was still alive in the world.

Yu Feilin's heart also knew very well that Zhou Tianlong was now going to form a new attribute in his body, and the difficulty could be imagined, and it was by no means something that could be completed so quickly in a day or two. Therefore, Yu Feilin knew that he couldn't help Zhou Tianlong, and the only thing he could do now was to accompany him here and wait until he finished refining.

At the beginning, Yu Feilin found that since Zhou Tianlong's body emitted a dragon groan, his expression was no longer so painful. Yu Feilin knew that it must be this dragon groan that helped Zhou Tianlong solve the difficulty of refining flames, and his heart was full of shock and curiosity in the face of this powerful and strange dragon groan.

During these ten days, Yin Huo didn't say a word. The only thing that could be heard here was the terrible and miserable sound of the crying of unjust souls coming from behind the black earthen wall, but after so many days, Zhou Tianlong and Yu Feilin were basically used to this kind of sound, and they would no longer feel afraid and afraid.

At this moment, Zhou Tianlong sank his mind into his body, staring at the blue flame that was wrapped in the middle by the golden dragon. After ten days of frantic squeezing by the golden dragon, that blue flame was only more than an inch long, and this length was basically about the same length as the true qi cyclone in the human body's dantian.

"It's almost time!" Zhou Tianlong nodded secretly, and then his mind moved, and the Saint Martial Heavenly Dragon Jue began to run wildly. And with the operation of the Saint Martial Heavenly Dragon Technique, the golden dragon suddenly became active as if it had been injected with hormones, and then it compressed inward again. And this compression was even more violent than every compression in the past ten days.

The flame also suddenly became violent, and the flames that were more than an inch long beat violently. After ten days of compression, it knew that it could not fight the golden dragon, and it had given up resisting. But now, it found that this golden dragon was actually an inch, and it no longer continued to resist, but it still wanted to bully itself, and this flame naturally refused to give up, and rushed towards the golden dragon again, wanting to rush out of the golden dragon's body.

On the contrary, under the frantic squeeze of the golden dragon, the length of the flame became smaller and smaller, but the shorter the flame was, the more powerful the energy contained in it became.

"Bang!"

When that flame was compressed to just over half an inch long, a muffled sound suddenly came from Zhou Tianlong's body.

And with the sound of this muffled sound, Zhou Tianlong suddenly found that there was finally a change in his dantian. It turned out that in his dantian, there were two true cyclones, one blue and one white, and at this moment, Zhou Tianlong found that next to those two true cyclones, there was another true cyclone. This true cyclone is also blue, and faintly, you can also see a slight flame beating in this cyclone.

Zhou Tianlong nodded secretly, knowing that this was the fire attribute true qi that he had just formed, but because his fire attribute came from the yin fire, it was naturally different from the general fire attribute, not showing fire red, but showing the unique blue of yin fire.

And now this true cyclone is still very small, only more than half an inch long, far from being comparable to the true cyclone with the two major attributes of wind and water. Zhou Tianlong knew that his fire attribute had just been formed, so it was still very weak, but as long as he continued to refine his fire attribute energy, it would definitely gradually become stronger.

"Haha Then, he opened his eyes suddenly, and laughed loudly.

"Did you succeed?" Seeing Zhou Tianlong's eyes suddenly open, and then let out a big smile, Yu Feilin was overjoyed, hurriedly walked to Zhou Tianlong's side, and asked eagerly.

"Hmm!" Zhou Tianlong nodded extremely solemnly, the joy and excitement could not be concealed at all.

"Great!" Yu Feilin couldn't help but be very happy, and couldn't help but step forward and hug Zhou Tianlong. After ten days of hard work, hovering on the edge of life and death several times, Zhou Tianlong finally broke out of the cocoon and became a butterfly, successfully realized his wish, and became a three-attribute martial artist.

But as soon as the two of them embraced, Yu Feilin suddenly realized that Zhou Tianlong was not wearing clothes at all at this time. At that moment, Yu Feilin's face was flushed with shame, as if he had been electrocuted, and immediately left Zhou Tianlong's body. At the same time, her eyes involuntarily glanced towards Zhou Tianlong's lower body, and she suddenly saw that thing, at this moment, it was actually stronger and thicker than before. Yu Feilin's pretty face was even redder, as if she was about to drip blood, and her heart was almost jumping out of her throat.

When Zhou Tianlong saw Yu Feilin's reaction, he was stunned for a moment, looked down, and found that he was not wearing clothes, and couldn't help but be greatly embarrassed. But his clothes had been burned by the high temperature, and there was nothing to hide here, he wanted to ask Yu Feilin for clothes to block it, but he felt embarrassed, hesitated for a long time, and didn't open his mouth.

Zhou Tianlong just wanted to talk to Yin Huo, but suddenly felt a burst of pain in his lower body, and couldn't help but be slightly startled.

"What's going on? My body was destroyed by the flames, and the pain in my body was taken for granted. But why did it hurt there?" Zhou Tianlong subconsciously grasped his place. He wanted to ask Yin Huo what was going on, but after thinking about it for a long time, he didn't know how to say it.

When Yu Feilin saw Zhou Tianlong's hand holding there, she thought that he was deliberately covering it because she was shy, but she didn't care about it at the moment, and slowly turned around, no longer looking at Zhou Tianlong's naked body.

Just when Zhou Tianlong was puzzled, the voice of Yin Huo suddenly sounded: "Boy, is there some pain in that place?"

"Hmm!" Zhou Tianlong's face turned red at this moment, and he nodded embarrassedly.

When Yu Feilin heard that Zhou Tianlong had pain in his body, he couldn't help but be shocked, hurriedly turned back, and asked Zhou Tianlong with an eager face: "Where do you have pain?"

"I ......" Zhou Tianlong "me" for a long time, but he still didn't say it, he really didn't know how to express it to Yu Feilin.

Yin Huo smiled: "That's the right pain there! You introduced flames into your body, forming the true qi of the fire attribute. It's just that your body hasn't adapted to such a domineering masculinity of the fire attribute for a while. That place is the foundation of yang in your body, and all the masculinity will converge in that place, so there will inevitably be pain there. ”

"Then what should I do?" asked Zhou Tianlong.

"Is there a way?" Yin Huo hesitated for a moment, as if he was worried about something, and said, "Using Yin Qi to dissolve Yang Qi can alleviate your pain there!"

"Yin Qi Dissolves Yang Qi?" Zhou Tianlong frowned slightly, not understanding what it meant, and asked again at the moment: "Please give detailed guidance from the seniors!" "Stupid!" Yin Huo scolded fiercely, and said: "Just find a woman to combine with you!"
