After this period of continuous practice, Tang Yun's Huangquan Void Transformation Technique has become more and more proficient, his body has turned into a Huangquan Void, and the whole person is between the virtual and the real, flying like a dusk light, not to mention as fast as lightning, at least it can be compared with those high-end and high-grade fighters in the previous life.

It didn't take too long for Tang Yun to bypass the huge mountain and fly to the other side of the mountain.

At this moment, something happened that surprised Tang Yun, only to see that she had just turned to the mountain peak for another time, when she heard an earth-shattering muffled thunder.

The loudness of this voice was simply unheard of, and he was caught off guard, Tang Yun was so frightened that he almost couldn't control the mana in his body, so he didn't get out of the Huangquan Phantom.

As soon as some of his uncertain minds moved, the whole person broke away from the Huangquan Illusory Shadow, and a ball of pure Gang Qi was suspended in mid-air under his feet.

Tang Yun, who stopped in mid-air, looked in the direction where the sound came from, and saw that there was pitch-black smoke and dust everywhere he could see, and the scene was as if a giant volcano had erupted.

The most peculiar thing is that the smoke and dust that sprayed up the air did not disperse with the wind, but condensed into a ball, no matter how the wind in the air blows, they also gather with each other, changing their form from time to time, just like the gust of wind that can break the skin of mortals does not exist.

Looking at the black smoke and dust in the sky, Tang Yun sighed, and he didn't know if this was a unique scene in the illusion, or if there was a similar environment in the outside world.

When he was admiring, Tang Yun's eyes suddenly froze, but he looked at the place where the smoke and dust were spewing out.

I saw that in the belly of the mountain below, there was a huge cave more than ten meters high, and countless black smoke and dust were sprayed out from the black cave, and the smoke and dust rubbed against the air, and from time to time there were bursts of thunderous noises.

Of course, Tang Yun was not concerned about these thunderbolts that could deaf people's ears, but on the top of the huge cave, which was engraved with the three ancient characters of "Lost Garden".

Looking at these three ancient words, Tang Yun's heart was dumbfounded for a while, she finally understood what Long Aotian meant by being extremely conspicuous, judging from this burst of thunder, this Lost Garden was indeed very conspicuous.

Just as he was sighing, Tang Yun found that the black smoke in the cave seemed to be sprayed out, and as the last trace of black smoke and dust erupted, the surroundings suddenly fell into silence again, only the black smoke and dust tumbling in the air from time to time told the changes here.

Glancing at the black smoke and dust in mid-air, Tang Yun hesitated for a moment, transformed into a Yellow Spring Phantom, and in the blink of an eye, he slipped into the cave with the three ancient characters "Lost Garden" written on it.

The cave was very deep, and the walls on both sides were very smooth, and it would not be an exaggeration to say that it was as smooth as a mirror.

After thinking about it for a while, Tang Yun reacted, this cave was a passage for those smoke and dust sprays, judging from the sound of those smoke and dust spraying and the sound of air friction erupting, the speed was unimaginable, and this cave naturally became smooth and smooth under the washing of smoke and dust for many years.

After flying along the cave for a few hundred meters, Tang Yun was a little surprised to find that the temperature around him had suddenly dropped a lot, and the direction of the cave had gradually begun to drill downward.

There was no fork in the road in this cave, and Tang Yun didn't think about it so much, he just flew towards the depths of the cave with his head stuffed, and flew out dozens of kilometers in a short time.

At this time, the cave became steeper and steeper, and eventually it even became a deep cave that went straight down.

Standing suspended above the deep cave, Tang Yun squinted his eyes and stared at the faint red light flickering below the deep cave, and he hesitated whether to continue deeper.

It's a dangerous place after all, and it's not good if you accidentally hang up.

While hesitating, Tang Yun suddenly felt a huge suction force coming from the deep hole, and before she could react, her body involuntarily fell towards the deep hole.

Tang Yun, who was taken aback, hurriedly used the Yellow Spring Void Transformation Technique, turning his body into a Yellow Spring Phantom, and the mana in his body gushed out even more frantically, resisting the extremely strong suction in the deep cave.

Soon, Tang Yun's falling speed slowed down, but there was another doubt in her heart.

But she just clearly felt that although the suction in this deep hole was extremely powerful, this force did not seem to be aimed at her, but attracted something else, and she was just an unlucky person who was affected by this force.

I was thinking like this, but I heard a loud "boom" behind me, turned around and looked, only to see that it was pitch black, and subconsciously pressed a hand on the center of my eyebrows, and my own mind went along the cave in the direction behind him.

It didn't take long for Tang Yun's face to change, but it was her divine mind that detected the overwhelming black smoke and dust rushing along the cave.

The black smoke and dust were extremely fast, and the sonic boom from the friction between the smoke and air could be heard in the distance, and almost in the blink of an eye, those smoke and dust had already approached Tang Yun.

It wasn't until this time, and then a little red came out of the bottom of the cave, that Tang Yun could see the appearance of those black smoke and dust clearly!

Where is the smoke and dust, it is clearly black ice crystals the size of thumbs!

As those black ice crystals approached, a cold breath came to his face, and with Tang Yun's current physique, he was also so cold that he shivered, and for a moment it felt as if his blood was going to be frozen.

Without any hesitation, Tang Yun turned around and flew towards the depths of the cave.

There was an extremely strong suction force in the cave itself, and coupled with Tang Yun's downward momentum, the speed was even faster than the black ice crystals behind him, and he soon left those black ice crystals far behind.

However, what surprised Tang Yun was that as she went deeper and deeper into the depths of the cave, the temperature around her rose rapidly, and in her feelings, it didn't take long for the temperature to rise from twenty degrees to sixty or seventy degrees.

If a mortal stays in such an environment, he will be roasted in a short time, not to mention that from time to time a hot air stream will be blown under the cave against the strong suction.

The temperature of those air currents was extremely high, and Tang Yun, who was sharp-eyed, could even clearly see that the air around him was scorched and distorted by this air current, and this phenomenon could not have occurred without hundreds of degrees of high temperature.

Rao is Tang Yun's body at this moment far surpassed the body of the mortal body in terms of strength, but he still didn't dare to use his physical body to touch these high-temperature countercurrents, so he had to break away from the Huangquan Transformation Technique, and cast the Huangquan Holy Body and Ripple Defense to block those high-temperature countercurrents from the body.

Although he was separated from the Huangquan Void Transformation Technique, Tang Yun's falling speed did not slow down, and he was still falling rapidly under the action of underground suction and inertia.

It didn't matter how much distance it fell, Tang Yun only felt that the temperature around her was getting higher and higher, and the appearance of that kind of high-temperature countercurrent became more and more frequent, even if she was hiding in the Yellow Spring River formed by the ripple defense, she could also feel the high temperature transmitted to her through the Yellow Spring River.

Fortunately, as she went deeper and deeper into the ground, the suction force became smaller and smaller, and finally the suction force even disappeared without a trace.

Without the traction of suction, Tang Yun was still falling rapidly under the effect of inertia, but soon she used the Qi Soaring Technique to stabilize her figure.

Tang Yun, who was suspended in the air, looked at his feet with a surprised expression, where a scorching fireball with a diameter of several kilometers was floating, and from time to time there would be violent explosions exploding inside the fireball, causing the surface of the fireball to tumble for a while.

This fireball looks exactly like the sun that is constantly undergoing nuclear fusion!

When Tang Yun was surprised, he felt an extremely cold power coming from above his head, and his mind swept away, only to find that those black ice crystals had fallen quickly.

This discovery made Tang Yun a little stunned, and he glanced at the fireball under his feet, but found that the fireball had packed the entire cave tightly, and there was no way to go around it on either side.

When she was anxious, she found that there was a small hole more than one person high on the mountain wall on one side, and Tang Yun, who was so anxious, didn't bother to find out what would be in the small hole.

Just as Tang Yun's front feet drilled into the small hole, those black ice crystals roared through the small hole, and occasionally a few ice crystals slipped into the hole and fell on Tang Yun's body, almost instantly, her body was frozen and stiffened, and she had to use all the mana in her body to expel the cold brought by these ice crystals.

Tang Yun, who had expelled the cold, looked at the black ice crystal flow whistling outside the small cave with some trepidation, and almost froze himself at the thought of just a few ice crystals, if he fell into this overwhelming ice crystal flow, he was afraid that he would die here even if he let out a scream.

At this time, Tang Yun had a sense of luck that she had escaped death, but soon, she thought of the fireball that numbered, that fireball was an extremely fiery energy ball, if it collided with this black ice crystal......

When two extreme energies collide together, there is bound to be an explosion!

For a moment, Tang Yun's face turned pale with fright, and he secretly screamed, "It's over", and then looked at the entrance of the cave with wide eyes. Even if she was really dead, she would have to see the spectacle of the explosion with her own eyes.

But to Tang Yun's surprise, the explosion she expected did not happen, until the black ice crystal stream all fell, and the outside of the small cave was completely quiet.

Tang Yun was stunned for a moment, poked his head out and looked in the direction of the fireball.

Just by looking at it, she was shocked by the sight in front of her, only to see a blazing red flame and a pitch-black ice crystal entwined with each other and spun rapidly!

These two extreme energies only fit together, but they do not merge or destroy each other, but are entangled and hovering around a singularity!
