The Black Card - Chapter 1216

[Chapter 1214 Another mysterious pattern]

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

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

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

Since there are tunnels, then the underground palace is not a particularly important discovery. The tunnels must be connected to some special existence. Otherwise, what is the purpose of digging out this tunnel so hard?

Of course, the tunnel may be an escape route, or it may be a secret passage connecting two places, but this is a temple, built to house the gods. Of course, the gods will not need to escape, nor will they need to use tunnels to escape. Dark passage song.

But Shi Lei discovered the problem at the other end of the tunnel.

He carefully recalled the way he came, and finally, he discovered that his current location was in the heart of Acropolis Mountain, and the location here was exactly under the highest point of Acropolis Mountain.

This means that it is located under the Parthenon.

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

Moreover, Shi Lei searched for three days in the Temple of Hephaestus. He could confirm that this secret passage was excavated after the Temple of Hephaestus was converted into a church.

And that vault is where the pivot controls the entrance.

This is the best way to preserve the original appearance of the Temple of Hephaestus as much as possible, while still creating such a tunnel underneath.

Shi Lei once again lamented the generosity of the ancient Greeks in architecture.

Now, all this would be nothing. Large excavators and various modern detection methods can easily help an engineering team carry out such a large project.

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

Next, what Shi Lei needs to do is to decipher the secrets of these three walls. He must open these three walls before he can enter the underground palace behind, and only then can he know why the architect wanted to carry out such a huge project. The interior of the Acropolis hill is hollowed out.

At the same time, Shi Lei also realized his danger, because the way to open the passage from the center of 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 go to heaven and no door to the earth. He will not be able to open the mechanism in the Temple of Hephaestus even if he goes back, but he will be blocked by these three walls when he goes forward. Way to go.

Still a little too risky.

A thin layer of cold sweat broke out on Shi Lei’s spine.

Without further ado, he began to study the three walls. He believed that based on his understanding of mechanical applications, the knowledge of these mechanical applications given to him by the black card completely exceeded the level of earth technology in mechanical applications. The secret of these three walls must be found.

If it doesn’t work out, he still has more than 24,000 reputation points. The worst he can do is exchange and learn Mechanical Application 25. I just don’t know if learning the second Mechanical Application card will require Shi Lei to use the six sensory cards. To develop your brain more.

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

On these three walls, there was a protrusion on each of the left and right walls. After Shi Lei looked at it with a flashlight, he determined that they were two ancient oil lamps.

He looked and saw that there was still lamp oil in the container under the oil lamp. When he shined his flashlight on it, it shone brightly.

As a church, the last moments of this place have been five or six hundred years ago, but the lamp oil here is still there?

Shi Lei didn’t dare to light the two lamps. Although it felt like there was air circulation here, it would be troublesome if the air circulation was not enough to support him and the two oil lamps consuming oxygen at the same time.

He had a flashlight anyway, so he didn’t need to rely on the light of an oil lamp.

Shi Lei tried to twist the oil lamp to see if the two oil lamps were the mechanism. However, the oil lamp itself did not move at all, and only the container below seemed to be removable.

After removing the container with lamp oil underneath, there was no change in the small room. Shi Lei knew that the mechanism was not in 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 method the ancient Greeks used, but the lines were so tightly sewn together that no gaps could be seen at all.

The patterns on these three walls are quite similar to the patterns on the ground in the Temple of Hephaestus, and they form a rectangle, just like the shape of a door.

This seems to further indicate that as long as there is a passage behind these three walls, these lines must be the key.

Shi Lei searched carefully in this trapezoidal small room, not missing every inch. However, except for the four circular potholes at the left, right, upper and lower corners of the front wall, Shi Lei searched carefully. Except, he found nothing.

Shi Lei realized the possibility that these four potholes might be the switches that control the door of the underground palace. However, it might require four people to hold the four holes at the same time to open the door.

If this was really the case, then it would be a lie. Shi Lei had calculated everything correctly, but he had not calculated that he was the only one.

He tried to touch the potholes one by one, and tried all sequence possibilities. The three walls were still three walls, without any change.

What should we do?

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

Perhaps, this is the insurance set up by the ancient Greeks to prevent people from being discovered here.

If the secret passage of the mechanism is opened from the outside, and when that person enters, the air circulation channel inside will be closed until the person passes through the small chamber and enters the underground palace beneath the Parthenon.

Only in this way can we be completely sure that the person who enters the passage knows the secret here.

And if an outsider breaks in, they will be suffocated here because there is not enough air and they cannot open the door to the underground palace.

This was really a scam. Shi Lei didn’t see any bones along the way. He subconsciously thought that there would be no danger here.

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

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

And if there was no break-in, how could someone 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, he must calm down, there must be some kind of mechanism here to let him leave, otherwise, all these exquisite designs will be useless.

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

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

The oxygen in the cell was getting less and less. Shi Lei glanced at his watch. It was around seven o’clock in the morning, and more than two hours had passed since he entered the tunnel.
