The mind was slightly in a trance, the scene in front of him changed, and the next moment, the feeling of the soles of the feet touching the ground appeared, and the mind was also sober.

"This is the third-layer hall of the Heavenly Venerable's Vault?"

Eyes swept around, and the three of them frowned slightly.

At this time, the place where the three of them were located was a high platform the size of five or six zhang square, and the ground of the high platform was depicted with mysterious lines, and the lines exuded a faint halo, but they were gradually weakening, and I thought that this should be caused by the three of them teleporting over.

Around the high platform, there are stone walls 100 zhang high on three sides, and in front of it is a deep and tall stone wall passage.

This is not so much the third hall as the corner of a stone passage.

"Look, there's a stone tablet there!" At this time, Yang Feng suddenly spoke.

Hearing this, Han Chen and the others followed the prestige, and sure enough, they saw that under the high platform, there was a stone tablet half a zhang high at the entrance of the stone wall passage in front of them.

The three of them got off the high platform and walked to the stone monument. The walls around are inlaid with a lot of light crystals, and through the soft light emitted by the light crystals, you can see a row of characters carved on the stone tablet.

"The realm of mystery, limited to five days, only 10,000 people will be taken, and those who cannot be bounded will be eliminated!"

Eyes swept over the stone tablet, and Han Chen's brows suddenly furrowed.

This stele was obviously left by the Sword Venerable powerhouse, and the meaning of the font on the stele was also easy to understand.

Like the first two floors of the hall, this third floor hall also has its own realm, called the Mystery Realm.

Look at the dark, endless passage of the stone wall behind the stele, and think about the meaning of the name 'Mystery Realm'. Obviously, this is a labyrinthine world of stone walls.

Unlike the previous two-story hall, this time there is a time limit, which is five days.

And there are also strict requirements for the number of people leading to the fourth floor of the main hall, only 10,000 people.

As for Han Chen and the others, they need to find the boundary jade that has entered the fourth layer of the main hall within these five days, and it needs to be within the first ten thousand. If it cannot be completed, it will be counted as elimination. Completely disqualified from continuing deeper.

"What does this knockout mean? Still" Yang Feng frowned, and slowly spit out two words, "Erase!"

Hearing this, Han Chen and Mo Chen's brows also furrowed.

The Celestial Treasure is not a good place. Ages. Every time it is turned on. I don't know how many warriors were buried in it. If the blood didn't dry up, I'm afraid this Heavenly Venerable Secret Treasure would have been drowned by the blood of those dead martial artists.

For the meaning of the last elimination word on the stele. Han Chen and the three of them really couldn't tell what they meant.

If it's just teleporting, it's better, it's a big deal to wait three days later, cross the second layer of the canyon abyss, and re-enter, even if you stop there, it doesn't matter.

But if Yang Feng's latter guess was a bit terrifying.

"Let's take a step at a time, the top priority at the moment is to find the boundary jade that leads to the next layer, otherwise, it's just empty talk!" Han Chen said softly as he moved his gaze away from the stone tablet and cast his gaze towards the deep stone wall passage.

Then he stepped over the stone monument and into the passage of the stone wall. Yang Feng and Mo Chen, who were behind them, glanced at each other, didn't bother any longer, and quickly followed.

The stone wall passage is very high, about 100 zhang, and it is also very wide, at least about fifty or sixty zhang wide, such a wide passage, Han Chen and the three of them walked in it, and they really felt small.

After about a cup of tea, the stone wall passage began to fork, and the first three directions on the left and right appeared. The stone wall passages in the three directions are the same size, and they are all deep, and I don't know where the end is.

After the three of them groaned slightly, they gave up the plan of choosing a passage for one person, after all, no one knew how big this mysterious realm was, and if the three of them were separated from this, it would be the real gain that outweighed the loss.

Moreover, this third layer is the same as the previous two layers, the transmission of Jian Yu is still banned, except for being able to check the soul breath of the other party, nothing else is useless, once it is lost, it will not be contacted, just like Han Chen at this time is once again separated from the absolute godless and others.

The three of them did not change their direction and continued to walk straight forward.

In the blink of an eye, an hour passed.

The three of them went around in circles, and they didn't know how many miles they walked, let alone how many times they changed their direction, but what they saw in front of them was still such a familiar stone wall passage, as if there was no trace of change, and this feeling was really uncomfortable.

"Huh, what is this?" Suddenly, Yang Feng let out a hint of surprise.

I saw that on the stone wall next to the three people, there was a gap three meters high and more than two meters wide, and the gap was so thin that if you didn't look closely, you could hardly see it.

Looking at the shape of this gap, it seems to look like a closed stone door.

Yang Feng pressed his hands on the stone wall and pushed hard, and in the sound of 'snort', the gap expanded, and the stone wall was pushed open a little inside.

"It can be pushed, it's really Shimen!" Yang Feng said with a happy face.

All the way to the present, the three of them are also a little tired, not to say that they are physically tired, but mentally. At this time, a stone gate that was hidden so deep appeared, and a trace of curiosity rose in the hearts of the three of them.

It is said that there are countless treasures in the Tianzun Secret Collection, but in fact, along the way, Han Chen has really not received any good things except for the five Enlightenment Pills from Xue Wuji's hands.

I couldn't help but have a trace of anticipation for this stone gate.

Snort

Yang Feng pressed the stone door with both hands, the true yuan in his body was running, and in the harsh friction sound, he slowly pushed it away.

Through the light emitted by the light crystals on the passage of the stone wall, it can be vaguely seen that behind the stone door is a closed stone room with a small space.

Han Chen took out two light crystals from the empty ring, held them in his hands, and walked in with Mo Chen.

A soft light emanated from the light crystal, illuminating the stone house transparently.

The stone room is about three meters high, more than ten meters longitudinal and horizontal, compared to the stone wall passage that is often dozens of zhang, this stone house is really small and pitiful.

In the corners around the stone house, there are some flowers and plants, different colors and varieties, it is hard to imagine how there can be plants growing in such a place where there is not the slightest soil, and it seems that the growth is extremely good.

"This is the Vital Flower, the Fire Leaf Grass, and the Silver Candle Branch" Han Chen's eyes widened, and he recognized these flowers and plants.

There are a total of eight kinds of herbs, although these eight herbs are not genius treasures, they are also extremely rare, and most of them are some of the main medicinal materials for refining four or five grade pills.

Han Chen took out the jade knife, carefully dug out several medicinal herbs, and then packed them in a jade box and put them into the empty ring.

After doing this, Han Chen did not breathe a sigh of relief, but turned around and looked at the center of the stone chamber with expectant eyes.

In the center of the stone chamber is a half-meter square stone pillar on which a closed stone box is placed.

The flowers and plants that grow around are all rare herbs, and the things in this stone box should not be ordinary goods......!
