"It's a metal plate, do you hear it?"

Xiao Xiong tapped lightly with his fingers and explained to Zhao, "It should be cast, in order to withstand people, the casting is particularly thick." But this flap doesn't look like it's cast, it's a little different from the surrounding materials,"

He tapped it with his hand, "If you guess correctly, this board should be made of wrought copper, thin on one side and thick on the other, without eccentric shafts, this design must be to solve the problem of eccentric weight that rotates to one side!" "Mobile SM..

"Well, it should be!" Zhao also knocked lightly twice, and sincerely agreed, "This old ancestor is quite capable?" When a person falls, it automatically closes, like a pedal, even if there is a companion, it is useless? This design is so fine, admire! ”

"Yes, this thing like an eccentric shaft, gravity has been falling to one side, with the help of the force we fell, it turned back again, quickly returned to its original state, the person who fell, didn't have time to react, it fell down, and the lock is so dead? If you fall, don't think about it! ”

Xiao Xiong pushed it up vigorously, "Look, there are automatic locking equipment on all four sides, to be honest, Gu Rao's design, it's really amazing!" At that time, it was amazing that such a sophisticated mechanism could be designed, it was amazing,"

Xiao Xiong also praised it from the bottom of his heart and pointed it out to Zhao.

"Yes, the lock is so strong, the person who falls down has only a dead end, this design is really amazing! Moreover, it is tightly seamless, and it is all metal, and it is impossible to smash or pry. Without special tools, it is impossible to disassemble the self-locking device from below, and it seems that you can only rely on the captain! ”

"If it's the same above, then you can only use a bulldozer," Xiao Xiong teased dejectedly,

"Don't be discouraged, let me ask the captain, he has been studying it for so much, there should be news, right?" Although Zhao was also a little discouraged, he still encouraged Xiao Xiong,

"Captain, it's all metal devices underneath, and it can't be opened at all, what are you doing there? Why don't you say anything? We're all suffocated to death," Zhao shouted loudly, and there was a "buzzing" sound in the earthquake's tomb.

"Don't worry, I'm thinking about it, this coffin is made of metal plates under it, and there is a flap in the middle, there is no place to start, but I have an idea I don't know if it will work, I'll try!"

"Okay, you try, but you have to be more careful, I'd rather not open it than fall off!" Zhao's is indeed telling the truth.

"I know, you guys get out of the way, I'm starting to pull the brass ring!"

In fact, Zeng Fan has not been idle on it, he has cleaned up the area around the flap very clean, and he can basically see it at a glance, "How can I open it without falling down?" He looked at the coffin and had an idea.

"Got it, we've gotten away, don't worry,"

"Okay, then I'll get started!"

Zeng Fan began to pull the copper ring up vigorously, and he heard a loud "boom", and the flap was opened again, but it was quickly closed again.

"Huh? What's going on? That? Xiao Xiong looked up at the flap, and the meaning was obvious, Mr. Zeng did not fall down with the opening of the flap.

"Oh, Amitabha, captain, don't take any more risks," Zhao shouted loudly, "This is not fun if it falls!" ”

"What's going on?" The two looked at each other.

It's no wonder they wonder, for this flap, the two of them are the most experienced, as long as they pull the copper ring, they will fall off involuntarily, but what happened to Zeng Fan?

It turned out that Zeng Fan was lying on the edge of the coffin and dragging it!

Ever since Zhao fell, he had been pondering. And doubly hearted, he knew that he couldn't fall anymore, and if he fell too, then there would really be no one to send a letter.

So, he studied it carefully for a long time, and he knew that as long as you stood inside the coffin, it was dangerous! Just stand outside the coffin and you'll be fine. Therefore, he had an extra heart, and he kept standing outside the coffin, and did not go into the coffin at all.

He knew that the design of this real and fake coffin was specially set up in case someone dug up the real coffin, and the tomb robber had to stand on this copper plate in order to work, and only when he pulled the copper ring upwards, the locked mechanism was opened, and the person stood there, and the weight was concentrated, and the person would inevitably fall.

"Wouldn't it be okay if I didn't stand in the coffin?" The smart Zeng Fan lay on the coffin board and leaned down. This is now, because the coffin is in tatters, and the distance between the top of the coffin and the bottom of the coffin is not too deep, and if the coffin is new, this trick will not work, because you can't reach it.

"But that's not okay, is it? The method is safe, but what's the use of closing the flap again? There are no tools below, and the speed of reproduction is so fast, how can you fix the flap? ”

Thinking of this, Zeng Fan was a little discouraged. Immediately shouted, falling is a death. Will they be able to get out of here? So half,

"Wow, Captain, what a pleasure!" Although the flap was closed, as it opened and closed, a cool breeze blew into the tomb, and the two of them were happy, inhaling fresh air, but they didn't expect that it was closed again after a while.

"Alas," the two men were very discouraged when they looked at the dark top of the tomb.

After repeating it like this a few times, Zhao became impatient, "Captain, can you fix it?" The air is fresh, and the speed is so fast, who is going to go out?

"Hey, I have an idea," Xiao Xiong, who had been speechless, seemed to see the strangeness, "Teacher Zeng, is there a wooden recipe on it?" ”

"There should be, you mean?"

"You find one or two of the right length, put them on the pedal, and then pull the brass ring, if the wood falls, it may get stuck!" From the last few pedal turns, he could see the doorway.

"Hey, that's a great idea," Zeng Fan agreed, "when I pull out that brass ring, I put the wood square on it, so that the wood can fall in, and I can jam the flap, and then, I use a horizontal log to completely block the pedal, so that the people below can climb out along the wood!" ”

"Okay, you wait, I'll go out and look for it," Xiao Xiong's words reminded Zeng Fan, and he was very happy, "This is the construction site, there should be wood, right?" He quickly crawled out of the grave.

"Old Xiao Xing? In the end, he is mechanical, smart, and has two strokes, "This idea is good, Zhao was very happy, and immediately praised it."

"Hehe, I don't know if it's going to work, I can only try it first, and it's up to Captain Zeng to find the right wood?"

"Oops, that's not a problem, how can there be no wood on the construction site? Rest assured! Zhao Le comforted him.

Unexpectedly, an even greater danger was coming...... read3;
