On the organ map, on the first floor of the tomb, the fangtang Dynasty marked the words "chamber in the tomb".

"Wang Mazi said that this is the middle room for the rest of the workers who build the cemetery." A right hand in the north corner of the room in the mechanism diagram: "the mechanism is here."

The mechanism diagram is full of complicated lines. Just in the north corner, from top to bottom, three square bricks bend 90 degrees.

Push three square bricks and rotate them 90 degrees to open the mechanism.

The design of the middle room on this floor is very ingenious. It's not a directly excavated space, but a combination of two movable walls. The walls are fixed with a circular axis. In space, the two walls are not the same size.

There is one less wall in the West. With the rotation of the square brick and the axis, the west wall will move 40 cm southward, revealing the entrance to the cemetery on the second floor.

Ah Zuo and ah you can't see the cleverness of this mechanism, but Fang Tang was greatly praised: "the wisdom of our ancestors is immeasurable, and only the simplest principle has created a mysterious mechanism."

A right some impatient, her game time is not much: "now turn off." Then he reached for it.

The sand on the north and West corners of the wall fell under the scissors in her hands.

Under the stripped sand, the blue bricks are arranged in order.

A right little bit of looking for, groping, from top to bottom almost every brick have touched, but there is no trace of organs.

Biting her lips, she lost patience again: "we've been cheated. There's something wrong with that picture."

Fang Tang frowned and touched it again. He felt strange in his heart.

"The mechanism diagram is absolutely right. I can't read it wrong."

"What if you're wrong!" A right stares big eyes: "so complex mechanism diagram, you can't remember all."

Fang Tang shook his head again: "never wrong!"

He believed in white, how could the machine go wrong.

The scene suddenly stiffened.

Ah you and ah Zuo looked at the north and West corners again. There was really no organ.

"It's impossible!" Ah Zuo wiped his sweat: "I remember very clearly. At that time, old lady Su squatted here, Wang Mazi stood in the East, and then the mechanism suddenly opened."

There was no problem with the location of the opening of the organ or the labeling of the organ map at that time.

"Could it be that this mechanism is one-time, once opened, it will be permanently closed?" Ah Zuo's face turned white.

"No way!" Fang Tang is also a little anxious. It's about Qin Yaxin's clue. He looks at the mechanism drawing again: "this mechanism is designed to be active, just for the convenience of access. It's not disposable."

The three squatted in the corner, all silent for a moment.

In the stiff atmosphere, kailinlin, who had been sitting on the ground, stood up with the north star. The beautiful policewoman whispered: "in the Republic of China, the writing habit was still vertical, from right to left."

"Well?" Fang Tang raised his head: "Linlin, say it again."

Kailinlin said coldly: "you are too flustered. You forget a basic fact. When Wang Mazi showed us maps, he always showed them from left to right. As far as I know, the writing habits of most places in the Republic of China were from right to left. I have read a lot of materials, and the thread bound books at that time were bound on the right!"

This is the writing habit that Chinese people have inherited for generations.

It was not until the new culture movement of the Republic of China that some intellectuals began to promote the writing order from left to right.

However, it has been a matter since the founding of the people's Republic of China that it has really become popular.

Kailinlin's words have pointed out the key point. Fang Tang patted his head: "Linlin, you are so good. It's true. Damn Wang Mazi, he's so cunning. "

He continued to look at the organization chart on the ground: "the order of the organization chart is also reverse. It indicates the north and west walls. In fact, the organization is in the East!"

Recalling the positions of Wang Mazi and Su Laotai at that time, ah you also understood: "Damn it, it was not su Laotai who opened the mechanism at that time, but Wang Mazi who stood in the East. He was facing us and opened the mechanism with his hand hidden behind."

Ah Zuo had already rushed to the east wall, just at the corner of the Northeast wall, and soon found the mechanism brick.

The green brick turns, creaking, and the entrance to the West appears.

Fang Tang picked up kailinlin and rushed in with the north star.

With the North Star leading the way, there is no need for torches and lanterns.I'll keep up with you.

Down a slope, a smell of decay came to my face.

There is a light ahead.

It is still a gas lamp, and the second floor of the tomb appears in front of us.

Fang Tang stood in front of the door of the tomb on the second floor. He was shocked and stopped subconsciously.

In front of his eyes, two dead bones fell askew in the tomb.

Ah Zuo and ah you went in behind him and looked into the dark interior of the second floor tomb.

To the north of the tomb, there are rows of sandbags. The sandbags are also painted with the words "Japanese military headquarters".

Before sandbags, there were rows of rusty and rotten weapons.

The uniform three eight big covers were Japanese army standard rifles at that time.

There were also several southern pistols, the handles of which were broken, leaving only a few parts.

Along these weapons, we can see the wooden boxes in the south of the second floor tomb.

Fang Tang covered kailinlin's nose with his sleeve: "be careful, the troops entering here are biochemical bacteria troops. I don't know what's in these boxes."

Ah you nodded and stepped back slowly. Ah Zuo cooperated with her very well, and the steel wire in the sleeve popped out suddenly.

The steel wire penetrated a rotten wooden box, and a pile of black particles rolled out of the box.

It was a strange particle wrapped in oil paper, like blackened rice, but as soon as it rolled out, it showed a strange fragrance.

"It's like plant seeds." Ah you looked at it from a distance.

"More than 80 years have passed, and these seeds haven't rotted yet?" "Said AZU.

Fang Tang held his breath.

In addition to these seeds, there are also withered branches in the wooden box. These branches are very familiar. They are the "cutting vine" seen on the mountain road when I came here.

"What do the Japanese do with these seeds?" Ah you said to himself.

Fang Tang looked at the south wall and frowned.

Under the south wall, two rusty iron rings were lying there, and the peeling marks could be seen on the wall.

"Wang Mazi, they destroyed the mechanism!" Fang Tang said in a deep voice.

The mechanism of the tomb on the second floor is a mechanical structure driven by underground water. It is necessary to peel off the wall, find two iron rings embedded in the wall, pull them out, and drive the underground water flow on the third floor, so as to push the mechanism to turn away.

"How did they destroy it?" A right stares big eyes.

Fang Tang touched his chin: "this mechanism was opened from the middle of the wall. After opening the mechanism, the two bastards chopped the iron ring with a samurai knife, and then took advantage of the short time before the mechanism was closed."

"The Third Tomb is where the treasure is."
