This place is an extremely huge spherical underground cavity. The upper dome and the lower pit are buckled in bowl shape. The thickness of the soul crystal here has reached an incalculable level, and the surface seems to be washed by some force all year round, making the four walls as smooth as a mirror.

However, the walls of the pit in the lower half look a little yellow. The closer they are to the central spring, the darker the color. The reason is that the rolling cold spring itself is extremely yellow, which makes the surroundings also show similar colors.

In addition, the extremely cold aura emitted from it. Even though Xiao Youran's body was filled with Taoist body, he still couldn't help but tremble. Of course, he was still at the outermost edge of the entire hole, and it was even colder inside. If he accidentally fell into the cold spring at the bottom of the pit, he would not think he could come out alive.

After carefully observing the Hanquan cave, Xiao Youran found that except for the entrance of the cave when he entered, there was only a narrow platform protruding the cave wall at the upper and lower dividing line, surrounding the cave for a while, as if in order to allow people to fully view the Hanquan from all directions, a plank road was specially built, but that was all, and there was no other exit.

"No..."

With a ugly face, Youran looked around again, and even looked up and looked carefully at the top of the cave. After discovering that there were indeed no other cave entrance, she wailed so much that she was so depressed that she wailed.

Unexpectedly, after going around in circles, I went so hard to get here. Xiao Youran, who was exhausted both physically and mentally, found that he had just crawled into a "crystal ball" from a "bottle"?!

If I had known this, I would have thought of a solution from the original place. How could I say that the bottle had at least a "bottle mouth". Even if the wall of the bottle was also naked, at least I could still make a hole and climb up, but the ball was sealed and there was no place to climb. Could it be that I had to return the same way?

Although she was a little depressed, Xiao Youran did not leave the place immediately. Anyway, she had already arrived, so she simply walked along the plank road first, just to take a tour and see if there were any weaknesses in the four circles of hole walls, or hidden secret passages, etc. Even if she had nothing to find, it would not be a waste of time.

With this mentality, Xiao Youran raised his hands on his back, swept his depressedness, and walked along the plank road with a smile, as if the person who was visiting here was savoring the natural wonders. Sometimes he nodded, sighed, sometimes knocked on the crystal wall, stamped the plank road, looking leisurely and contented.

Not to mention that he had walked like this, he really discovered something. When he reached a quarter of the plank road, he found a stone tablet embedded on the crystal wall. The surface of the tablet was level with the cave wall. I don’t know what material it was. It was neither smooth nor reflective. Its color was similar to the soul crystal. If it weren’t close, it wouldn’t be able to see its true appearance in the distance!

Looking at the surface of the monument, there are only two dark gray ancient characters "Huangquan" in the upper half, and there is a brief introduction to the ancient characters in the lower half. Perhaps the monument was erected too long, and the large characters on it are better, but the inscription below has been somewhat weathered and worn, and the handwriting is extremely light, and the "knowledge" with a leisurely smile can only be recognized.

"The Yellow Spring, the nine secrets of the earth, is one of the nine springs, and is located in the east and the position of the lid. The spring is filled with cold and storm, and it will devour the soul. It will continue all day long, and the soul can also be burned and destroyed. If you want to pass through this secluded, you must refine the soul to..."

After reading this, the inscription behind it was completely blurred. Xiao Youran almost put his face on the surface of the monument, but it was still difficult to distinguish the exact content. He was still unsatisfied and couldn't help but exclaim that he was disappointed.

"It seems that even the soul can't run out after falling into it. This is really...uh~!"

Thinking of this, Xiao Youran was so scared that he shivered. There was no text on the left and right, and he no longer tried to identify it.

"Can this soul still be refined?"

While muttering, he continued to move along the plank road, and laughed and recalled the inscription. Although the refinement of the soul would sound extremely absurd to anyone, just as he kept shaking his head at this moment, for some reason, there was a sense of inexplicable recognition in his heart.

"I'll be good~!"

Xiao Youran, who had already walked to the opposite side of the entrance of the cave, couldn't help but be curious. He took out a half-eating roast goose and threw it hard at the bottom of the pit. As a result, the roast goose had just flew out not far away, and was shot out by the Huangquan, which had sensed, and instantly burned into nothingness. He was so scared that he exclaimed, and he couldn't help but lean his body inside again, almost sticking to the wall of the cave.

This plank road seems flat and stable, but in fact it is also built by soul crystals. Although it is not as smooth as the surrounding crystal walls, it is not very rough. It is easy to slide if you are not careful, and there is no guardrail at the edge. Xiao Youran doesn't want to "fall you will be a long-lasting regret."

He walked away one quarter of the time with some trembling fear. He was directly opposite the stone tablet inscribed in Huangquan. Xiao Youran found that there was an exact same stone tablet embedded on the wall of the cave. The text on this tablet was very simple, and there was only a very large word "prison" on the entire monument!

"What does this mean?"

Looking at the big words on the stone tablet, Xiao Youran scratched her head in confusion. What does this "prison" mean? Does hell? But isn't hell in the underworld? Then what kind of prison is here?

After looking around, Xiao Youran did not find any entrances or exits like the prison gate except this stone tablet. Maybe this is another meaning, right? But he didn't have time to think about these things now, and moved forward until he returned to the entrance of the cave when he first entered.

After exploring all the way, there was no other outlet here as I imagined. Although I was mentally prepared, Xiao Youran was still a little depressed. However, although there was no outlet, the mysterious energy was relatively sufficient. Since that is the case, you might as well try practicing here for a while to see how fast the cultivation level is improved.

Xiao Youran thought about it and returned to the front of the Prison-word Stone Stele, sat down facing it, and began to use Tongyou Jue to absorb the mysterious energy. It was not that there was any special place, but he was still very curious about the meaning of this word, and wanted to guess and analyze it while practicing.

Time passed, and with the support of natural mysterious energy, Tongyou Jue was much faster than when it was breeding with medicine power, and it was smoother. Several large circles passed by, Xiao Youran felt that his cultivation level at the peak of the Yellow Level seemed to have improved a little, and he felt like he was touching the barrier of the Xuan Level.

"Prison... Huangquan... Huangquan... Huangquan... Huangquan Prison?!"

While feeling the changes in his cultivation, he looked at the word "王子" without blinking until he murmured the three words "Huangquan Prison", he suddenly felt his vision was hazy, and the words seemed to suddenly disappear. A blurry figure appeared and appeared on the monument, as if he was waving at him?!

He smiled in a daze, and heard the figure seemingly making a sound similar to a summoning. He subconsciously stood up and walked to the stone tablet, slowly raised one hand to touch it. When his fingertips came into contact with the surface of the monument, the originally dark gray word "jail" suddenly burst out with dazzling yellow light, and his people also disappeared out of thin air with the yellow light...

"Who dares to go to hell privately?!"

A cold shout with anger scared her dazed smile. After suddenly waking up, she found that she had come to a dark and cold underground prison at some time. At this time, two people wearing Yin soldiers were standing opposite him with hook knives, and the tall and thin man on the left was the sound of the sound.

"What? Hell?! Isn't this Huangquan Prison?"

Xiao Youran, who had just woken up, was a little confused again.

"You are just pretending to be stupid! Isn't Huangquan Prison a hell? Say~! Who are you and how did you come in?"

The tall and thin Yin soldier glared at him and asked coldly. Xiao Youran's mind was a little confused, and he was even more stunned when he asked. Seeing this, the Yin soldier was immediately angry and took out a soul-locking chain and was about to go forward to take action, but was stopped by his companions next to him.

"Let's go, you see, he looks like he is wearing a bad uniform and the waist brand..."

The person who spoke was a wide-brow, narrow-faced ghost soldier who was patrolling with the thin-browed and narrow-faced ghost soldier. Following the direction of his finger, the thin-browed ghost soldier vaguely saw this guy with a dirt-faced guy who came out of nowhere actually had a nine-star bad waist card?!

"Are you a fool? Which brigade from? Why are you here?"

After seeing the waist card, the tone of the thin and tall Yin soldier was significantly relieved, but he was still extremely serious, and he looked like he could not answer.

"Hey~?Laughing brother?!"

At this time, someone suddenly said in surprise.
