It turned out that after Donnie handed the lotus lantern to Anne for study, he looked up boredly and studied the bronze statue of the fairy on the secret door to see if he could find out the secret mechanism. Pen? Interesting? Pavilion wWw. ｂiquge。 Info At this moment, he accidentally caught a glimpse of a looming outline on the wall where the secret door was located, and the outline changed impartially with the light from the lotus lamp in Anne's hand, and when he was about to walk forward and accidentally blocked the light of the lotus lantern, the outline disappeared.

When Anne heard Donnie say this, she turned her head to look, and sure enough, she found a vague outline on the wall, and as she brought the light closer to the wall, a looming painting appeared in front of her, which was the outline of a person facing away from her, walking with a lotus lantern in his right hand, and what was even more surprising was that the lotus lamp was impartial and exactly the same as the one in her hand.

Anne exclaimed, this is too much of a coincidence, is this a hint? The sudden appearance of the painting is as if someone is prompting them to carry a lotus lantern through this secret door. Feeling a little incredulous, she told Stern and Downey about the discovery and her thoughts, and asked them what they thought of the sudden appearance.

"Obviously," said Downey, "the meaning of this painting is for us to carry this lamp through this secret door. ”

"I think that's pretty much what it means, if not more than that." Stern continued: "The man who designed this mechanism was very clever, because in the first place, we would not have found the painting if Downey had not taken it down in the first place. And in this painting, you say that a person holding a lotus lantern in his right hand is walking in the direction of the stone wall, that is, if we want to pass through this secret door, we must first take down this lotus lantern, but before the lotus lantern is taken down, we must first activate the mechanism on the lotus lantern and close the stone door connecting the spiral ladder, and after the lotus lantern is removed, the light shines on the stone wall, and the painting is revealed. In this way, the lotus lantern is connected to two steps at once - closing the stone door and the painting on the secret door. These mechanisms are interlocking and indispensable. There's a good chance there's one last step, Donnie, and you're pushing the secret door again now. ”

With that, Donnie pushed the secret door, and sure enough, the secret door was easily pushed out of a crack. Seeing that this secret door was easily pushed out of a crack, Donnie was amazed and delighted, amazed at the ingenuity of the design of this mechanism, and pleased that his unintentional move actually cracked this mechanism with such a secret design at once.

"Then we can push open the secret door and go in now, right?" Donnie asked Stern, and although he found the mechanism, he knew that it was Stern who could already open the secret door, so he asked, in fact, he couldn't wait.

"Yes, but we need to be careful. Let's push it aside and look at it for a while. ”

After Stern finished speaking, Donnie pushed the secret door hard, and with the sound of a dull secret door rubbing against the ground, the secret door was pushed open, and at the same time, a gust of wind suddenly blew in the face, blowing the candle flame in the secret room almost extinguished, Anne saw that there was a wind and hurriedly protected the lamp in her hand, so it was not blown out.

But Donnie was in the middle of the stroke, he was blown upright, thinking that something was about to rush in behind the secret door, so frightened that he retreated again and again, hid to the side, and made a fuss in his mouth: "Is there a ghost coming out from behind this secret door!" How suddenly a gust of wind came for no reason! ”

Anne looked at the darkness behind the secret door, the wind only blew for a while and then stopped, and she didn't see anything, so she said: "It should be the wind caused by the air pressure difference, the space behind the secret door may not have circulated for a long time, and the air in the secret room forms an air pressure difference, so the moment you open the stone door, there will be a burst of air flow, which is normal." ”

After Anne finished speaking, she was relieved to see Donnie carefully peek into the secret door of the black hole.

"To make sure there's no danger, I'd better go in and check first." Anne suggested.

So Anne took the sandalwood lotus lamp in her hand as in the painting, walked to the secret door that had been opened, first took the lamp and shone it in, but found nothing unusual, and then walked in, and after a few steps, she found a stone staircase that was oblique in front of her. The staircase was long and steep, and there seemed to be no end, but she guessed that it was a passage to the outside of the grotto, so she turned and called Donnie and Kansa to help Stern in.

"Annie, what's behind the chamber?" Stern asked before Kanza and Donnie were about to step through the secret door, for he hesitated a little when Anne said they could enter the secret room.

"I saw only a stone staircase leading upwards with no end in sight, and I didn't find anything unusual other than that."

"It's okay, don't worry, Sergeant, all I saw was a long stone staircase inside." Downey had already stepped half his foot into the secret door, and he saw that there was nothing but the stone wall and stone steps illuminated by the lotus lamp in Anne's hand.

Hearing Donnie say this, Stern was relieved to be helped by Donnie and Kansa to step through the secret door.

"Bang-bang!"

Just as Anne led the three of Donnie to the first step, the secret door behind them suddenly closed automatically!

"What's wrong? What happened? Stern asked anxiously when he heard the sudden sound of a secret door closing behind him.

"This secret door closes automatically!" Anne hurried back to the secret door, and found that the secret door that had just been open had suddenly turned into a wall! It was exactly the same as when they first discovered the secret door, except that there was an extra door frame on both sides, which seemed to be made of some kind of metal, and the light shone through, and the cold light appeared. Anne tried to push the secret door, but found that it couldn't move, and checked the door frame again, and there was no obvious sign of the mechanism.

"It's so strange, this stone wall here is a smooth wall except for a metal door frame, and there are no other traces of mechanism, so how did this secret door close automatically? And how do they open the secret door? ”

Stern said, "Forget it, let's keep going up, leave him alone, I guess they designed this purpose." ”

Downey asked, puzzled, "But why did they design it?" Even opening a secret door is so complicated. ”

"Isn't that obvious? There are so many strange and dangerous creatures up there, and if you don't pay attention, you can escape from the stone chamber. It's the same thing that we're in our laboratories where we research chemical weapons have set up layers of protective doors to prevent viruses from leaking. They have to have such a facility, otherwise if they forget to close the door one day, it will be the end of the world. ”

Stern shrugged his shoulders and continued, "But now it looks like they're the end of the world." ”

Hearing what Stern said, Anne gave up looking for the mechanism that opened the secret door, and she re-stepped up the stone steps, walked in front of Stern and them, and continued to walk up the stone steps. He also said, "Hearing you say that, I think that's what happened." Anne gestured to the lotus lantern in her hand: "You see, the secret room is like a quarantine room, connecting the stone steps leading to the outside and the stone room leading to the strange creatures, separated by a secret door and a stone door, respectively. Then they used this lotus lantern as a key to turn off and on, which was a double layer of insurance, just to make sure that their lab animals would not escape through the passageway! ”

Downey exclaimed, "Oh my God! Did these Khmers already develop such an advanced civilization in the Middle Ages? It's incredible! ”

Anne said disapprovingly: "Actually, it's not hard to guess, after all, they built the world's largest temple building, the Angkor Temple." There are also a series of temples around Siem Reap, both in terms of architectural scale and artistic prowess, which illustrate the creativity of the Khmer people at that time. So in their heyday, it was normal for their economic strength to be able to give birth to such an advanced civilization in other aspects. ”

"By what you say, I have a feeling that the weird creatures they're raising here seem to be a kind of bioweapon they're building, like our country is working on, you know."

Needless to say, Anne knew what he was referring to, but she immediately remembered an archaeological mystery that the professor had told her: "If you talk about the biological weapons of the ancients, these Khmer-raised biological weapons are simply not worth mentioning." ”

"What is it? Is there anything more powerful than these creatures? ”
