The darkness in the cave does not see the five fingers, as soon as you come in, there is a feeling of coldness, Yue Qianchou feels a little strange, usually, glowstone is mostly used for lighting in such a place, why not use it here, to let people walk in the dark. In addition, in the cave where there is usually a ground fire, as soon as you enter, you can feel the rising temperature, but here it is cold and a bit abnormal.

Could it be that this birdman pretends to be a pig and eats a tiger, and wants to pit Lao Tzu? Yue Qianchou immediately cheered up his spirit, and as soon as he felt that something was wrong, he flashed people. I couldn't see the road conditions, and I walked with the sound of the crane in front of me, and at the same time, my divine sense was also released to explore the way, and the terrain was always sloping downward. Heli didn't say anything when he noticed his senses.

After a long while, the divine sense detected a corner in front of them, and after the two of them turned in, a misty green light appeared in front of them, and the outline of the cave could already be seen clearly. At the end, it was another turning point, and then turning in, the eyes suddenly brightened, more than ten meters ahead, a cyan light curtain with a radius of several meters surging like water ripples, the green and faint is beautiful, but it looks a little weird.

Heli pointed ahead and said, "Inside is the green fire, the temperature is extremely high, with your cultivation, you must be prepared to resist it." ”

"But I didn't even feel the slightest heat, what's going on?" Yue Qian wondered.

"Do you see that light curtain? It is the formation laid by the predecessor of the divine craftsman, which can block the temperature leakage inside, and the green fire inside is protected by a light shield, so you can't feel the heat. Heli explained.

"Tsk, there is also a formation that can insulate the temperature, it seems that the temperature of this green fire is really not ordinarily high, otherwise it would not have taken so much effort. Yue Qian said with a sad head, his eyes with a hint of surprise, trying to see through the light curtain.

"Don't let the heat leak out, the main reason is that I don't want too many people to know that there is a green fire here, and the big array outside the valley is also the same reason. Heli said and pointed to the way he came: "The approach to the cave is deliberately dug so tortuously, as a precaution that the leakage of the fire of the green fire will attract attention. ”

"Oh!" Yue Qian nodded with a clear understanding, and said, "The big array outside hides a killing machine, presumably this array is not only the function of heat insulation!"

"I don't know the trick, it's easy to get in and hard to get out, and I will eventually be roasted to death by the green fire, and it is estimated that no one in the world can stay on the edge of the green fire forever. Unless the green fire is extinguished, this array is maintained by the energy of the green fire, and once the green fire is extinguished, the array will cease to exist. Speaking of this, Heli smiled as he walked: "Don't you want to see it, you can go in and have a look now." ”

Seeing a ripple of the light curtain, he easily walked into the light curtain without the slightest effort. Yue Qian was amazed, and followed cautiously, not feeling any resistance, as if the breeze was blowing, and the person had already arrived inside.

As soon as he came in, although Yue Qianchou was ready for luck, he was still taken aback, the temperature was so high that it almost suffocated him on the spot, and the speed of Zhenyuan's operation was still a little unbearable when it was raised to the limit. This was something he had never encountered since he cultivated the fire technique, and it was said that he was no longer afraid of any fire, but he was still roasted by the temperature of the spread of this green fire. Immediately secretly ran the fire technique, for a while, finally resisted this almost cruel high temperature, at this time he breathed a sigh of relief, he knew that the fire technique could absorb mortal fire such as earth fire, but he was not sure that it had an effect on green fire, and now he tried to eliminate the doubts in his heart, and then he had the mind to look around.

This is a huge hemispherical space, wrapped in a light mask, the ground is very flat, it is estimated that there is a radius of four or five hundred meters, there is a pit about dozens of meters wide in the middle, a cyan flame rises from the pit "ho", bewitching, poignant, lonely and full of passion unrestrained burning, the cyan light emitted illuminates the entire underground space, everywhere is the same color of green and sparkling.

There is no doubt that this is the legendary green fire! Yue Qianchou was taken aback again, the green fire in the pit was at least more than two hundred meters away from where he was standing, and the temperature of light diffusion was only afraid that it could be higher than the flame release in his body, if the fire element in it was extracted and used with the fire technique, it would be repaid!

After the shock, there was joy in my heart. His eyes fell on the two of them, and they saw that their hair, skin, and clothing were all turned blue by the firelight. looked at Heli's face, but saw that the other party's expression flashed a trace of surprise, and quickly disappeared when he looked over, Yue Qianchou sensitively captured it, and suddenly felt a little bad, and couldn't figure out what was wrong for a while.

"Brother Yue is really hidden, and the cultivation in the Dan period can actually resist the high temperature of the green fire. Although I can't see through Brother Yue's cultivation, I'm afraid Brother Yue is not just a cultivation in the Dan period!" asked Heli with a smile.

Yue Qianchou's pupils shrank suddenly, and finally understood that something was wrong, and sighed in his heart, this guy knew that the cultivation of the Dan period could not resist here, and he didn't tell Lao Tzu, and brought Lao Tzu here, what did he want to do? He smiled bitterly when he didn't find anything: "Brother Crane really lifted me, the power of this green fire is really not blown, I have already run the true yuan to the limit, it is really hard to resist." I wanted to take a closer look, but I really didn't have that kind of cultivation, hey! It's enough to look at it from a distance. Forget it, Brother Crane, let's go back quickly! If I stay any longer, I'm afraid that my life will be lost here. ”

After saying that, he turned around and wanted to go out, and he secretly held a small silver ball in his palm, which contained a small drop of his own essence blood, just stay outside and find a chance to leave the silver ball in the hole, and it will be easy when he comes back next time. Who knew that the light curtain that came in just now was effortless, and when he went out again, as soon as his body touched it, there was a rebound force, which bounced him back a few steps.

Yue Qianchou looked back and said in surprise: "What's going on?"

"Brother Yue, have you forgotten what I started to say to you? If you want to enter and exit this big array that protects the green fire, you don't know the trick to get in and out, and you will eventually be burned to death by the green fire. Heli shook his head and sighed.

Yue Qianchou waved his palm and slapped his forehead, and said, "Look at my memory, I forgot what I just said." Hey, Brother Crane, take me out! If I stay any longer, I'm going to be burned to death by this green fire. ”

The smile on Heli's face suddenly became hideous under the light of the cyan fire, and he smiled gloomily: "Didn't you try your best to trick me into taking you to see Qinghuo?

After speaking, he played a trick towards the light curtain, and his figure quickly passed through and flashed out. Although Yue Qianchou's cultivation and speed are not as good as his, his reaction is not slow, and as soon as the other party's body moves, he immediately sticks to it, but after all, it is still a little slower. As soon as the other party passed the light curtain, he followed again, and was immediately shocked by a huge rebound force that made him take more than a dozen steps back. Then there was a smug smile from Heli outside: "Yue Qianchou, I forgot to tell you, don't underestimate this light curtain, the greater its force, the greater the rebound power, even if the master of the god transformation period enters, it is difficult to come out without the help of a good spiritual treasure, haha!"

It turned out that this was not soundproof, and Yue Qianchou looked around leisurely inside, but said in a nervous tone: "Brother He, don't joke, if you continue to make trouble, you will die." ”

"Do you think I'm joking?" He Li Yin smiled: "Yue Qianchou, don't blame me, blame you for not coming to the Demon Domain, blame you for not letting the old immortal look at you." Blame yourself for not being clever, when others are fools, you have to come to see Qinghuo, if it weren't for that, I wouldn't dare to attack you, haha!"

"Uh......" Yue Qianchou twitched, it turned out that he was being tricked by others. Thinking about the other party's words, his eyes narrowed and said, "Old immortal?" Heli, the old immortal you are talking about is Bi Changchun?"
