In the dark underground passage, only the footsteps and breathing sounds of Zhao Baliang and Xiaobai seemed a little strangely silent.

However, a moment later, a faint light appeared in front of the two of them, and there was a faint fluctuation of spiritual energy, coming from the front.

Zhao Baliang's gaze froze slightly.

This passage has circled dozens of times, gradually going deep into the ground, and now it is dozens of meters deep underground, but here, there will be light!

After groaning for a while, Zhao Baliang gently grabbed Xiaobai's palm in front of him, and with a slight force, pulled Xiaobai behind him.

Xiaobai was slightly stunned, but said, "You ......"

Zhao Baliang shook his head, even in this darkness, Xiaobai could still see Zhao Baliang's movements and expressions.

"Don't worry! Even if there is danger here, it's just a formation mechanism, and I'm better at this than you!"

Xiao Bai hesitated for a moment, and just wanted to say something, but when he thought of Zhao Baliang sitting quietly for five days, and then easily breaking the scene of the bronze array on the ground, he didn't speak.

If it was before, Xiaobai, who also had the inheritance memory of the beetle snake clan, would not admit that he was much worse than Zhao Baliang above the formation!

But now, in those five days, Zhao Baliang's understanding of the way of the formation has obviously made an extremely terrifying leap, and even Xiaobai has to admit that the current Zhao Baliang is indeed stronger than himself in the formation!

In the depths of the ground, if there is no life, naturally there will be no living creatures, if there is danger, it should be a formation or a mechanism!

With the strength of the two of them, the skill of the mechanism is not a problem, and it can't create any threat, and the only thing that can pose a threat to the two of them is the formation!

Therefore, Xiaobai didn't say anything, and obediently let Zhao Baliang walk in front, but her eyes were sharp, and under the condensation of her mind, she kept scanning the surroundings, trying to discover the crisis in this underground cave in advance!

I continued to walk forward for a while, and the light in front of me became more and more obvious.

After turning around, the front of the two suddenly lit up!

The next moment, Zhao Baliang and Xiaobai fell into a complete stupor!

What appeared in front of the two of them was a huge underground cavern!

This underground cave is nearly 100 meters deep underground, but it is 100 meters in circumference and nearly 10 meters high!

Neither of them had ever seen such a large underground cave!

What's more, this underground cave is as if it were daylight!

The eyes of the two of them swept slowly and somewhat sluggishly across the entire underground cave, but they were shocked to find that the reason why this underground cave can be as bright as day is because the cave wall of this cave is inlaid with dozens of night pearls the size of a fist that shimmer with crystal light!

Night pearls are not too precious, but the dozens of night pearls in front of you are different!

In the secular world, the common night pearls are at most only the light that lasts for decades, or even hundreds of years! Moreover, those night pearls are all polished, and they are not as round and clear as naturally generated.

However, the dozens of night pearls embedded in the walls of this cave are completely different!

These night pearls have obviously been here for thousands of years! However, above these night pearls, the flickering light is still gentle and bright, and there is no sign of abating!

Moreover, there is no sign of artificial polishing on each night pearl, it is completely naturally generated! However, these naturally generated night pearls are almost perfect in condition, completely similar in size, dozens of perfect spheres!

If these night pearls are auctioned in the secular world, I am afraid that each one will be enough to auction for tens of millions, or even hundreds of millions!

These night pearls alone are a dazzling wealth! The most important thing is that these things are extremely rare! In the secular world, they are rare to see in decades and hundreds of years! At this moment, the two of them saw dozens of such superb night pearls at once!

Dozens of night pearls reflect each other, illuminating every corner of the entire underground cave, the entire oval cave, there is no dead end, although the light is not as dazzling as the sun, but it is delicate!

After a long time, Zhao Baliang and Xiao Bai's eyes were retracted and concentrated on the center of this cave!

In the center of this 100-meter cave, there is a stone platform.

The two of them could see at a glance that this stone platform was clearly artificially built, but what surprised the two of them was that this stone platform was clearly connected to the ground!

At a depth of 100 meters underground, the ground here is already a complete stone, and the ground of the entire underground cave is a complete bluestone!

And the stone platform is carved directly on this bluestone!

On the stone platform, there is no pattern, just an ordinary carved stone platform, it can be seen that the people who built this stone platform did not pursue beauty, but just regarded this place as a storage place.

On the stone platform, there are two boxes, one large and two small, the small box is only the size of a human head, and the big box is more than half a person high!

Xiaobai's gaze focused on the three boxes, and after looking at them for a while, he withdrew his gaze.

However, Zhao Baliang on the side did not look at the three boxes for the first time, but looked at the stone platform and the walls of the entire underground cave!

A moment later, in Zhao Baliang's gaze, a faint look of shock slowly emerged!

Xiao Bai on the side noticed the change in Zhao Baliang's expression, and hurriedly asked softly, "What's the matter?"

Zhao Baliang took a deep breath, calmed down, and regained his composure, then smiled bitterly and looked at Xiaobai: "You take a closer look at the entire stone room, as well as the stone platform!"

Xiaobai was stunned, although he didn't understand what Zhao Baliang meant, but he still looked at it carefully.

After a while, Xiao Bai turned back suspiciously and looked at Zhao Baliang.

She didn't find anything strange, it was just an ordinary stone chamber!

Zhao Baliang didn't speak, just stretched out his hand and gently knocked on the wall inside and outside the entrance of this stone room.

The two of them stood at the only entrance to this underground cave, Zhao Ba's arms were raised, backwards, in the passage, and forward, in the stone room!

In the two caves inside and outside, with the gentle tapping of Zhao Baliang's fingers, two completely different sounds came out!

Xiao Bai was slightly stunned, but then reacted violently and looked at the stone room!

Under Zhao Baliang's knocking, Xiao Bai Fang noticed that outside the stone room, the walls in the passage were clearly earthy! Even if there were some stones in it, there were not too many!

But the walls of this stone chamber are entirely stone!

It stands to reason that at the same depth, the composition of the soil should be about the same, how could such a completely stony stone chamber appear inexplicably above such a depth?

At the moment, Xiaobai's attention was on the walls around the stone room!

Just watched it for a moment, Xiaobai gasped!

At this moment, after careful observation, she finally found that there was not a single crack in the entire stone room!

If this stone chamber was made up of large stones, Xiaobai would not be so surprised!

After all, even with Xiaobai's strength, digging a passage, digging a hole in the ground, and then sending stones into the ground through the passage, building such a stone chamber, although it is troublesome, it is not impossible!

However, in the stone room in front of me, there was not a single sign of stone splicing on the wall!

This can only prove one thing!

This whole stone chamber is clearly a huge stone!

Discovering this, Xiaobai's mind couldn't help but have such a picture.

Thousands of years ago, a cultivator with advanced cultivation selected a huge bluestone, opened a door from a certain direction of the bluestone, and then followed this door, directly hollowed out the entire interior of the bluestone, and built this stone room!

Then, in the middle of the valley, on the ground, this cultivator was forced to dig out a deep pit with a depth of 100 meters, a radius of 100 meters! Then, the huge stone chamber was placed at the bottom of this deep pit, and then the 100-meter ground that was escaped was used to refill this deep pit, and a long passage was dug out, leading to the door of the stone chamber!

Then, that cultivator even refined a bronze plate with a radius of hundreds of meters, covering the ground of the valley, and carved an earth-shattering array on it to suppress this transformed ground!

At this moment, Xiaobai thought that just above the ground, he already felt that something was faintly wrong.

The ground covered by the bronze plate seemed to be slightly different from the ground that was not covered.

It's just that Xiao Bai didn't pay attention at that time, and the ground was full of bronze fragments, so Xiao Bai didn't think deeply!

But now, her eyes gradually widened, and she looked at the stone room in front of her in shock!

From above the ground, a spiral passage with a depth of nearly 100 meters was carved downward, which was not too difficult for Xiao Bai, who was already a half-foundation cultivator!

However, there is such a big effort, take 100 meters of bluestone, build a stone room, and then move the mountains to dig out a huge pit with a depth of 100 meters, bury the stone room, and build such an earth-shattering formation, covering everything under the ground, such means, such courage, but Xiaobai is ashamed of himself!

In fact, if Xiaobai really wants to do it, it will take more than ten years to do it, and he can also do it!

However, that was more than ten years!

And how long did it take the person who really did all this in the first place?

Xiaobai gasped, his expression was shaken, but he was a little speechless.

Zhao Baliang had already regained his composure, and after a moment of silence, he slowly took a step.

Seeing Zhao Baliang's action, Xiao Bai subconsciously hurriedly spoke: "Be careful......!

Her voice hadn't fallen yet, but Zhao Baliang smiled slightly: "Don't worry!

Xiaobai was stunned and looked at Zhao Baliang with some doubts.

How did he know there was no danger here?

Zhao Baliang didn't explain, just walked slowly towards the stone room.

Xiaobai also suppressed the shock in his heart and walked in as well.

Just a moment later, the two of them came to the stone platform in the center of the stone room and looked at the stone platform with a radius of more than ten meters!
