"It's a very good material, a thin piece can withstand the dense impact of stones, and if it can be studied thoroughly, it may be a new business miracle."

Jiang Yingxue sighed sincerely, thinking more about the commercial value of this material.

"The stones that make up the pyramid are very good nanostructures, but humans with modern technology can't replicate them.

Not everything can be successfully reverse-copied, and the things in this ancient ruin are the crystallization of the science and technology of the Fourth Civilization, and we can only sigh and speculate about it. ”

Bai Ning replied sullenly, like a bucket of cold water poured on his head, but it was not unreasonable.

Aren't they just speculating and sighing for no reason?

If you can understand everything by looking at it, it is impossible for this place to become a dead place, and they will have to go around in circles.

The direction of the fourth civilization's scientific and technological development may be fundamentally different from the current earth technology, and in a different logical structure, reverse replication is impossible.

Seeing that Bai Ning was struggling to clean up the rubble on the ground, Jiang Yingxue also hurried up to help, and after a while, a large blank area was cleared out.

A large mesh of unknown materials was exposed, and a black hole in the area below was a deep tunnel leading to nowhere.

Bai Ning tried to warp the grid, but the small grid was like a welded ground, and it didn't move at all, making people suspect that it was already one with the ground.

"If it could have been easily lifted, it would have been smashed open by the rubble in the previous turbulence.

This area is clearly waterproof, and we may indeed be on the lowest level of the ancient ruins. ”

Jiang Yingxue commented slightly, feeling a little helpless about this thin barrier.

There are no bolts, no solder joints, as if the thin grid is integrated with the ground.

Bai Ning, who did not give up, bombarded him with a knife a few more times, but he still did not move, not even a scratch was left.

With such a hard material, I don't know if it can be opened with explosives.

All possible places have been searched, and it seems that this underground chamber has really become a Jedi, imprisoning Bai Ning and Jiang Yingxue here.

Doors can't appear out of thin air, and people can't disappear out of thin air, so what's wrong?

For this strange space, Bai Ning buried his head in thought, but there was still no progress at all.

It's like a puzzle without any hints, and it's hard to move forward.

After pondering for a long time, Bai Ning's gaze suddenly focused on the ceiling above his head, and he had questions about this last unexplored area.

When they first arrived, there seemed to be nothing on the ceiling, but that doesn't mean that nothing else will ever exist on the ceiling.

The entire underground ruins are a whole, and there may be some mechanisms hidden on the ceiling, not to mention that they only explored part of the area in the first place, and the rest of the area is still completely unknown.

People will speculate and assimilate other areas because of habitual thinking, and after being cornered, Bai Ning can only focus on the ceiling dozens of meters high.

Perhaps, Aaron was really kidnapped by something that existed on the ceiling, and the doorway that had been discovered earlier was also hidden by the stone slabs that had fallen from the ceiling.

Extrapolating this possibility, the arrival of Bai Ning and the others activated some mechanisms in the ancient ruins, perhaps a mechanism for responding to the enemy or a defense mechanism.

Without continuing to do the follow-up in-depth reasoning, Bai Ning picked up the flare gun and projected a flare in the direction of the ceiling, the strong white light brightened the entire space, and part of the true face of the ceiling was also revealed.

As Bai Ning expected, Ah Long was bound to the ceiling at this time, looking like he was bound by something tentacle-like.

As the parabola of the flare progressed farther away, a door appeared on the ceiling, as if the underground chamber had been turned upside down.

Bai Ning felt that the reason why he and Jiang Yingxue were spared might be because the other defense mechanisms existing on the ceiling were incomplete, and the remaining tentacles were only enough to capture Ah Long alone.

At this time, Ah Long did not know whether he was alive or dead, and they couldn't climb up to a height of dozens of meters, and a sense of powerlessness once again filled the team of two.

The equipment they carry is indeed too pale and powerless here, and the walls of such a huge space can move when they say it, and they can't even make a sound, which is completely a contrast of crushing the plane.

What's more, the defense mechanism in this place has also been activated, even if that tentacle only captures Ah Long alone, but being able to deal with Ah Long silently is not something that Bai Ning can contend with.

In addition to the tentacles on the ceiling, Aaron's flashlight was also floating in mid-air before, suggesting that there may be some other mechanism here.

Although it is also possible that Ah Long was kidnapped, Bai Ning had just come to his senses, and his tentacles hurriedly retracted back to the ceiling, causing the flashlight to fall to the ground.

"What to do, at present, we can only wait for Ivan and their support to arrive, and we will have the ability to touch the defense mechanism on the ceiling."

The threat above her head made Jiang Yingxue very helpless, not to mention whether she could save Ah Long, and now she couldn't even say whether she could leave here safely.

If the tentacles took advantage of Ivan and the others to tear the ropes, they would be trapped here forever.

"It's not a big problem, Ivan estimates that he will bring down some heavy weapons such as RPGs, and since the tentacles can be damaged, it means that its own material is not very tough, and there is a possibility of being destroyed.

In addition, the tentacle is a fixed target, and it poses less of a threat to us. ”

For this only surviving tentacle, Bai Ning is currently more concerned about what the meaning of its original existence here is.

According to the previous reasoning, the explosion of Tunguska was the explosion of the spirit aggregation device, so this huge space is a device that secretly stores the energy of the spirits.

In this way, the tentacles on the ceiling are most likely equipment used to capture and secure the victims.

It may be aggressive, but the main role is functional.

"Two or three kilometers is not a small distance, and if Ivan wants to transport people and materials, it will inevitably take a long time."

The meaning of Jiang Yingxue's words is very clear, Ivan's role is always the icing on the cake, and if they want to successfully solve the crisis here, they have to rely on the current equipment in their hands.

Bai Ning didn't respond to this, and in his mind, he was thinking about the ghost incident of the previous bright flashlight.

If the energy here is a spirit, could it be that some of Aaron's previous actions, such as the exploration of the door, activated some of the remaining spirit stocks here, which will lead to a complete change in the pattern here?

As soon as he thought of this, Bai Ning took out the crystal nucleus and took a look, the red crystal nucleus seemed to be emitting some kind of unknown fluorescence, making it highlight a strange beauty here.

The anomaly of the crystal nucleus is obviously an echo of some of the mechanisms here, but no one can understand it.

"You say it's a key, but now judging by its appearance, it does have some potential."

Jiang Yingxue was also very curious about the changes in the crystal nucleus, and because she couldn't peek into the mystery of it, she could only give a kind of surprise to the onlookers.

"Spontaneous combustion of animals is really the key to opening up some of the mechanisms of ancient ruins.

It's a pity that we weren't lucky enough to encounter spontaneous combustion of animals, and perhaps, this little remnant soul in my hands alone won't make much use at all. ”

The abnormality of the crystal nucleus, even the tentacles on the ceiling could not be alarmed, which shows that the quality of the crystal nucleus is still very small here.

If it is possible, Bai Ning really wants to realize the spontaneous combustion of animals here, so that it is possible to completely open up the situation here.

"The crystal nucleus in your hand has no attraction to the tentacles, why was Ah Long silently kidnapped by the tentacles?

Could it be that Ah Long was already on the verge of spontaneous combustion in the human body, so he was kidnapped by tentacles. ”

In Jiang Yingxue's existing cognition, she believed that Ah Long would never rashly try some dangerous actions under unknown circumstances, let alone easily touch the unknown switch of unknown items.

Regarding Jiang Yingxue's emphasis, Bai Ning also thought of Ah Long's possible situation of spontaneous combustion in the human body, and he immediately took out a compass from his backpack and looked at it, but did not find any magnetic field disorder.

"Judging by the current external representations, the probability is not too high.

Since the entire ancient ruin is still functioning benignly, it means that it is not the only source of energy, and the spirit energy spilled out by the spontaneous combustion of animals may be able to force some parts of the ancient ruins to work again, but it may not have any effect on those parts that are still functioning.

The things here are badly damaged, and the overall operating mechanism may have been chaotic for a long time, and the crystal nucleus in my hand cannot cause the tentacles to move, which does not mean that the crystal nucleus is meaningless here. ”

Bai Ning's argument at this time was more of a speculation, even if Jiang Yingxue wanted to refute it, it didn't make any sense, not to mention that she didn't have any capital to refute.

This underground cavity is full of fog, danger is hidden from high places, and they do not have a comprehensive understanding of this place, everything is based on speculation, and arbitrarily assuming and denying a possibility is an external manifestation of falsehood.

Bai Ning still explored the place at his own pace, and the stone gate quietly shifted from the side to the ceiling, which was more like an overall defense mechanism.

The surrounding stone walls seem to be seamless, but behind them there is supposed to be some special mechanism behind them.

Beneath the ground is a cavity that connects to an unknown area, and how can the combination of the other five surfaces form a silent mode of operation?

Could it be that the stone wall is like a huge piece of precision, just because the errors between the connections are so small that the naked eye cannot see any traces of movement?

As for the sudden appearance of the doorway in the ceiling, it is very likely that it is just an image deception.

In this way, the displacement formed by this kind of unwitting stealing beams and changing pillars is the most subtle, and the movement caused by it can also be silent.

With this in mind, Bai Ning fired another flare in the direction of the doorway in the ceiling, and then picked up the gun in his equipment and slammed it towards the ceiling.
