Chapter 1214: Mysterious Patterns Appear Again

There must be a larger underground palace behind these three walls, and the underground palace is where the treasures are hidden.

Of course, there may not necessarily be treasures, or perhaps this is just a refuge left by the ancient Greeks.

Of course, this is not the key. The big problem Shi Lei discovered is because of the underground palace behind these three walls, but it is not entirely.

Since there is a tunnel, the underground palace is not a particularly important discovery. The tunnel must be related to some special existence, otherwise why would it be so hard to dig out this tunnel?

Of course, the tunnel may also be an escape route, or a secret passage connecting two places, but this is a temple, built for gods to live in. Gods certainly don’t need to escape, nor do they need to use tunnels to communicate secretly.

But Shi Lei found the problem at the end of this tunnel.

He carefully recalled the way he came here, and finally, he found that his current location was in the belly of the Acropolis Mountain, and the location here was just below the highest point of the Acropolis Mountain.

This means that this place is located under the Parthenon Temple.

The secret passage under the Temple of Hephaestus is actually connected to the Parthenon, which is a very magical thing in itself.

Moreover, Shi Lei searched in the Temple of Hephaestus for three days. He can be sure that this secret passage was excavated after the Temple of Hephaestus was converted into a church. And the arch is the key to control the entrance.

This is the best way to keep the original appearance of the Temple of Hephaestus unchanged to the greatest extent, while creating such a tunnel underneath.

Shi Lei once again sighed at the great work of the ancient Greeks in architecture.

In modern times, all this is nothing. Large excavators and various modern detection methods can easily help an engineering team to carry out such a large project.

But more than a thousand years ago, such a work was great.

And next, what Shi Lei needs to do is to crack the secret of these three walls. He must open these three walls to enter the underground palace behind, and to know why the architect had to carry out such a huge project and hollow out the interior of the Acropolis.

At the same time, Shi Lei also realized his own danger, because the way to open the passage from the belly of the Acropolis Mountain to the ground must be behind these three walls.

He must break through these three walls, otherwise, he will have no way to the sky or the ground, and he will not be able to open the mechanism in the Temple of Hephaestus if he retreats, and the way forward is blocked by these three walls.

It's still a bit too risky.

A thin layer of cold sweat seeps out of Shi Lei's spine.

Without further ado, he began to study the three walls. He believed that with his understanding of mechanical applications, the knowledge of mechanical applications given to him by the black card completely exceeded the level of mechanical applications of earth technology, and he would definitely be able to find the secrets of these three walls.

If it really doesn't work, he still has more than 24,000 reputation points. At worst, he can also exchange and learn mechanical application 2\5. I just don't know if learning the second mechanical application card requires Shi Lei to use the six sensory cards to develop his brain more.

Fortunately, with the previous experience, Shi Lei quickly found the possibility of opening these three walls.

On the three walls, there is a bulge on each of the left and right walls. After Shi Lei used a flashlight to illuminate them, he determined that they were two ancient oil lamps.

He looked and found that there was still lamp oil in the container below the oil lamp. When the flashlight was shone over, it was bright and reflected light.

This place was a church, and the last moment was five or six hundred years ago. The lamp oil here is still there?

Shi Lei did not dare to light the two lamps. Although it felt like there was air circulation here, if the air circulation was not enough to support him and the two oil lamps to consume oxygen at the same time, it would be troublesome. Anyway, he had a flashlight and did not need to rely on the light of the oil lamp.

Trying to twist the oil lamp, Shi Lei wanted to see if the two oil lamps were the location of the mechanism, but the oil lamp itself did not move at all, only the container below seemed to be removable.

After removing the container with lamp oil below, there was no change in the small room. Shi Lei knew that the mechanism should not be on the two oil lamps.

He walked to the front wall again, and found that there were some lines on the wall. When Shi Lei entered here from the main hall, the opening was opened from the lines. I just don't know what means the ancient Greeks used. Those lines are so tight that there is no gap at all.

The lines on these three walls are quite similar to the lines on the ground in the Temple of Hephaestus, and they form a rectangle, just like the shape of a door. This seems to show that as long as there is a passage behind these three walls, then these lines must be the key.

Shi Lei carefully searched in this trapezoidal room, not missing any inch of the position, but except for the four circular holes in the four corners of the left, right, upper and lower corners of the front wall, he found nothing.

Shi Lei realized a possibility that these four holes might be the switch that controls the door of the underground palace, but perhaps it would require four people to hold these four holes at the same time to open the door.

If this is true, then it's really a bummer. Shi Lei had calculated everything correctly, but he didn't expect that he was alone.

He tried to touch the holes one by one, and tried all the possible sequences. The three walls were still three walls, without any changes.

What should I do?

Shi Lei couldn't help but panic. He could even feel that the oxygen in the room was decreasing. The air circulation here was based on some unknown principle. It seemed that the air here had stopped circulating since he came in.

Perhaps this was a safety set up by the ancient Greeks to prevent people from discovering this place.

If the secret passage was opened from the outside, and when that person entered, the air circulation channel here would be closed until that person passed through the room and entered the underground palace under the Parthenon. Only in this way can it be completely confirmed that the person entering the passage knew the secret here.

And if an outsider broke in, he would be suffocated here because of insufficient air and the inability to open the door of the underground palace.

This was really a big pitfall. Shi Lei didn't see any skeletons along the way, and he subconsciously thought there would be no danger here.

However, no one died here, and there is another possibility, that is, this place has never been discovered by anyone.

No one discovered it, so naturally no one broke in here.

And if no one broke in, how could anyone die here?

Shi Lei felt a little sad. Could it be that he would be the first person to die here?

No, Shi Lei warned himself that he must calm down. There must be some kind of mechanism here to let himself leave, otherwise, all these exquisite designs would be useless.

Shi Lei simply sat down on the ground and tried to calm himself as much as possible, so that his demand for oxygen would be much less.

He carefully recalled every discovery he made here. Although it is indeed possible that at least four people would work together to open this door, it is also possible that Shi Lei has not really discovered the mystery of this underground palace door.

The oxygen in the small room was getting less and less. Shi Lei glanced at his watch. It was more than seven o'clock in the morning. He entered this tunnel and it had been more than two hours.
