According to Master Lian's conjecture, there is only water on the top of the ancient pagoda here, and if this water is determined to be mobile according to Xu Ran and Huo Sifar, then the source of the activity must be nearby.

Although spatial changes here can cause the compass to malfunction, there is evidence for it if it is measured according to the ancient method.

Otherwise, it would be impossible for the ancients to build those pyramids through the arrangement of the five elements, and those pyramids belong to auxiliary towers, Luo Hongtao had found some clues when he explored before.

Therefore, after Master Lian calculated according to the ancient calendar, he could roughly determine the direction of the changes of the five elements.

That's right, the arrangement of the five elements here changes from time to time, because the machines in the pyramid have been running non-stop for 800 years, which is easy to calculate.

If it's not the whole year, then it's troublesome, and if you have to use a supercomputer to calculate it with the brainpower of Master Lian, I don't know if it's going to be the Year of the Monkey.

In fact, the five elements represented by those towers are the four directions of gold, wood, water and fire, and the ancient tower in the middle monopolizes the water line, so the law of the four pyramids running around the ancient tower is easy to grasp.

According to the law, even the master chose a pyramid at random, and after entering, the corpse puppets in it stopped functioning, and they went down the stairs according to the gap that opened in the ground when the original pyramid mechanism was opened.

This staircase was the place where Xu Ran had experienced the mechanical monster after encountering the opening of the mechanism in the golden characters, but now they had to go the opposite way, and they had to take the initiative to go to the most dangerous place.

This is also the way Master Lian said to seek a glimmer of life.

Those mechanical monsters represent death, which means that the door of death has been opened, according to the operation of the five elements, to deal with the life gate on the Bagua Array, then they have to go around four times through the connected passage under the pyramid to find a way out.

Fortunately, the mechanical monsters entrenched in the tunnels had lost their energy, and they were all stationary now.

When a few people went down to a tunnel, they found that there was a mechanical monster guarding there every five meters in the tunnel, its face was hideous, and the weapons it carried were also quite sharp, if these mechanical monsters were driven, it would be a dead end here, and no living person could easily pass through this passage.

But now it's different, when Xu Ran used the space key to absorb the energy in the mysterious box, the mysterious box frantically absorbed all the energy in the entire main priest temple, so the energy blocks on these mechanical monsters also lost their energy, and they were naturally motionless.

As the saying goes, a drink and a peck have their own fixed number.

If it weren't for Xu Ran inadvertently taking the mysterious box, it is estimated that the mechanical monsters in this passage would have been guarding this death passage all along.

As expected, when the people walked through the middle of the passage, they could see some bones, but most of them were of animals, and some of them resembled the bones of apes.

Judging by these bones, it seems that they were all killed by those mechanical monsters.

But there were only scattered bones in front of them, but as the few people went deeper, they would find that there were more and more bones there.

Until the deepest place, there was a huge pit there, and I saw that the bones in the pit were piled up, and there were even human ones, which made the scalp tingle to see.

Not only that, but near that huge crater, there was a very large machine, and I don't know what it was for.

But the machine seemed to have stopped running for a short time, and from the machine there were still some unground bones remaining, and a trace of blood had not yet dried, and there was a smell of blood, which made people feel very disgusting.

This made Xu Ran suddenly think of the stone houses he saw on the second floor of the ancient tower, when he approached, he could smell an unpleasant stench, presumably the gases transmitted by those pipes should have come from the processing here.

"Everyone be careful, cover your mouth and nose, the gas here may be poisonous!"

The black girl who was walking in front felt a feeling of nausea when she passed by a mechanical facility, so she quickly reminded everyone and took out a gas mask from her backpack and put it on.

The others also took out their gas masks from their backpacks and put them on, and then walked through the bone-strewn place.

After passing through there, there will be more mechanical monsters that can be seen, but fortunately, those mechanical monsters are also motionless without energy and power supply, but it will also make people feel chills when they look at it.

There's a big hall around a row of mechanical monsters past you.

The hall looks like a steel castle in a sci-fi blockbuster, full of a mix of ancient and modern, but mixed with some of the styles of ancient traditions, and the walls of the hall are all human faces, with pipes from overhead, and they don't know where they lead.

However, under the huge human faces, which were more than three meters high, there was a metal gate, which was now semi-closed.

Fortunately, they are all half-closed, and there is still a gap that a person can get through if he is not fat.

But with so many doors, I don't know which one to choose.

Master Lian didn't study those gates, but just stomped left and right in the hall, and couldn't help but say: "There should be a mechanism under this ground, it should be able to move, and this place is closely connected to the human face, it is estimated that behind so many doors, there is only one passage to go out!"

Luo Hongtao looked at those doors, there seemed to be a kind of mark on them, and said: "I have some impression of that mark, as if each one represents a choice!"

"That's right, we're lucky, now that it's out of operation, and those doors are temporarily fixed, we can choose calmly, if this is the state of operation, once we choose the wrong one, it will be troublesome!"

But Huo Sifar didn't speak all the way, she kept writing and drawing on it with a notebook, as if she wanted to draw all the lines here, probably because she wanted to come again next time.

Buzzing!

Suddenly, at this moment, the ground shook suddenly, startling everyone.

"What's going on?"

Master Lian looked in amazement at the place where the tremor was most intense, and saw that there was a human face in that place that was gradually cracking, and it was about to collapse at any time.

After he saw the mark on the face clearly, Master Lian's face changed slightly: "It's not good, the face of the person looks like it's going to collapse, judging from the mark, it is estimated that this is the way out, quickly, immediately!"
