"Huh?" Just when Ye Xuan was hesitating and thinking about whether he should go back, or go up to check it, he suddenly "saw" a very faint wisp of smoke floating in the air, this light smoke was extremely thin, if it weren't for Ye Xuan's mental existence, in this darkness, he wouldn't have noticed it at all.

Because the whole body had been wrapped with telekinesis, isolating the breath outside, Ye Xuan didn't know what this smoke was, and groaned for a while, Ye Xuan let go of the telekinesis that enveloped his whole body, his nose twitched a few times, and a choking smell came to his nose, and he raised his eyebrows, "Sulfur?" ”

I didn't expect it to be the smell of sulfur, Ye Xuan had fought with the fire qilin before, and he had also smelled a faint smell of sulfur on the fire qilin, but it was not so strong, let alone so emitted in the air.

After muttering for a while, Ye Xuan once again covered his whole body with his mental power, and he decided to take a step forward, if he fled from the wind this time, the fire qilin would definitely leave a shadow in his heart, which would be extremely detrimental to his future cultivation.

Walking forward on tiptoe extremely carefully, he came to the end of this road, Ye Xuan carefully stretched out his head like a thief, only to see that the end was also a four-way road, and at the corner of the fork on the left, there was a faint red light refracted from it.

"It seems that after I go back, I must let Vanke see if I can make some high-tech detectors for mosquitoes and flies, and it is really inconvenient to lose my mind." After sighing secretly, Ye Xuan hesitated slightly, walked out of the fork in the road, and walked towards the glowing corner.

The more he walked around that corner, the higher the temperature in the air he felt, and Ye Xuan found that the ground of the entire fork was getting drier and drier, and when he reached the end of the corner, the ground had dried up.

Turn around that corner. When I looked again, I found that the light did not come from this fork in the road, but from the right side of the cave at the end of the front, and the light here was only refracted by the mouth of the cave.

After walking here, Ye Xuan already felt that the temperature of the air was at least thirty or forty degrees, almost like a hot summer.

Now Ye Xuan already knows. It shouldn't be a fire unicorn in that cave, because from his previous experience with the fire unicorn, although the flame on the body of the fire unicorn is also extremely hot, reaching more than a few hundred degrees Celsius, but its flame temperature is its energy, just like the true qi in the human body, it is generally only placed around the body to achieve a certain energy balance, although it is scary to look at. But if you don't get closer, you won't feel it.

And now in this situation, such a temperature can be felt from such a distance, obviously this does not meet the characteristics of the fire qilin, the fire qilin is a divine beast, but it is not a star.

Since he guessed that it was not a fire qilin, he naturally didn't need to be so careful, and walked towards the cave that emitted light.

The further you go to the cave. Ye Xuan felt that the temperature was getting higher and higher, even though he had mental power around him to protect himself. But Ye Xuan also felt the heat wave scorching, and when he reached the entrance of the cave, the temperature in the air reached at least forty or fifty degrees Celsius, and streams of black and yellowish smoke floated out of it, and even the ground was scorched black as if it had been baked by fire.

When I looked up into the cave, I saw that at the end of the cave near the cave wall, there was a thin piece of fiery red magma flowing slowly against the cave wall like a stream. The magma pierced through the walls of the cave on the left and right, and it was unknown where it came from or where it flowed, and it was clear that this was just one of its paths.

"It turned out to be magma." Watch as the heat rolls in, roasting the air above into twisted and steaming magma. Ye Xuan couldn't help but raise his eyebrows, and suddenly thought that the sulfur smell on the fire qilin should have been contaminated by living in magma for many years.

Seeing that it was just magma, the temperature inside was not extremely high, although the magma river was only less than a meter wide, but the temperature in the cave was at least seventy or eighty degrees Celsius, so Ye Xuan didn't stay any longer, and drilled directly into another cave next to him, intending to continue on the road.

"Huh?!" After walking into this cave, Ye Xuan suddenly felt that the originally scorching temperature had become a little cold, even if he had mental power to protect himself, Ye Xuan could feel such a huge temperature difference.

One side is hot and the other side is cold like winter, and there is such a high and low temperature difference between only a stone wall, no one believes that there is no problem.

This underground palace is extremely mysterious, it is said that it is the hiding place of the dragon vein left behind after the feathering of Xuanyuan Yellow Emperor, Ye Xuan pondered for a while, and decided to take a risk to see what is strange here.

As soon as the mind moved, the mind slowly flowed in all directions like water, three meters, five meters, ten meters, twenty meters, fifty meters......

"Huh?" Suddenly, Ye Xuan, who was originally using his divine thoughts to scan, paused, and in his divine thoughts, he found that behind the stone wall on the right side of this cave was an underground cold spring that exuded cold air, no wonder this cave could be cold in winter, presumably it was the cold air emitted by this underground cold spring through this stone chamber.

Nature is really magical, hot as a furnace and cold as ice, it can be described as two heavens of ice and fire!

After knowing the reason, just as Ye Xuan wanted to withdraw his thoughts, he was suddenly stunned, and then his pupils widened, and his face showed surprise and joy, "The ancients said well, if it is really a mountain and a heavy water, there is no way out, and the willows and flowers are bright and another village, the ancients are honest and do not deceive me, haha!" ”

Suddenly, Ye Xuan laughed, then his figure flashed, and he flashed towards a cave in front of him, and after turning a corner, he came to another cave next to him, only to see that this cave was more than a hundred square meters in size, the ground was dry, and only some black vines were born on the stone wall.

However, Ye Xuan did not observe this stone cave carefully, but instead rushed towards a cave on the inside of the stone cave that was one meter five or six high and could only allow people to bend over.

Slightly hunched down and walked into this cave that was only about one meter five or six high and one meter wide, turned the corner in front of him, and the dwarf cave in front of him suddenly opened up, and then he saw that the dark cave that should not be able to reach out to his fingers was actually covered with dark red flame light.

With the light of this flame, Ye Xuan clearly saw that the stone wall of this cave was crawling with a kind of purple-red vines, and between the purple-red vines hung some small fruits the size of strawberries, like rubies, and it was the dark red flame light emitted by this small crystal fruit that illuminated the entire stone room.

And this kind of crystal fruit that emitted the light of a dark red flame was the blood Bodhi that Ye Xuan had been looking for for days but couldn't!
