At this time, Ma Xiwen took a wooden board and stuffed it along the crack in the door. Then Wang Yuesheng also went through the crack in the door.

"What is he doing here?" I was a little puzzled by the altar.

Xu Yunshu explained: "He first used a wooden board to open a gap in the top of the stone, then put the nail on the stone, then held the bottom of the nail and slowly lifted the stone while pushing the tomb door. When the tap stone is completely upright, the tomb door is opened......"

After Xu Yunshu said this, the altar and I also somewhat understood the working principle of tap stone and crutch nails. But over there, Ma Xiwen and Wang Yuesheng's work was not so smooth. Wang Yuesheng didn't get it right several times, and he was sweating profusely when he was in a hurry.

"Liu Jinlong, you come and hold the plank!" Ma Xiwen called another intern, Liu Jinlong, to hold the plank for him, while he himself took the crutches in Wang Yuesheng's hand, and said with an extremely dissatisfied face: "It's really stupid that your hands are more stupid than your feet!" Wang Yuesheng's face turned red and stepped aside.

"Young people, they don't have much experience, so it's good to follow you to experience more in the future." Pu Yifan persuaded him beside him, and Ma Xiwen's face finally softened.

Don't say it, the crutch was in Ma Xiwen's hand, and it was set in the middle of it only once, and soon pushed the stone door open.

"Ginger is still old and spicy!" Park Yifan praised with a smile.

"Mr. Park has won the award!" Ma Xiwen said modestly, but the expression on his face was still triumphant.

The jar looked at it seriously, and it seemed that it was very interested in things. He patted me and said, "Poor ghost, study hard, you can learn all the skills." Maybe one day our brothers will be able to use it? ”

I glanced at him and said, "Do you mean open or close?" ”

"Of course it's open!" The jar cried, "Shut the door, that's what the dead can use." ”

Looking at the heavy stone door that was slowly opened, I couldn't help but praise: "This thing looks simple, but it's really practical." I don't know who came up with it? ”

Xu Yunshu smiled and said, "I don't know who came up with it, but I know that this thing is the invention of a tomb robber." ”

Tan Zi interjected on the side: "You see, in the end, you still have to rely on the wisdom of the masses, don't you?" This Luoyang shovel was invented by tomb robbers, and this crutch nail was also invented by tomb robbers. It seems that this tomb robber is not useless, and there are some people with brains among them. ”

Xu Yunshu said: "Yes, it's a pity that it's not used on the right path!" ”

Tanzi suddenly turned his head and asked me, "Is she talking about us?" ”

I glanced at the jar, I had really seen someone who picked up money and had never seen someone who picked up scolding, so I opened my mouth and said to him: "You are too careful, with your IQ, you are definitely not close to having a brain." ”

Open the stone gate, and behind it is a wide bluestone passage.

Situ Feng shone his flashlight inside, only to see that the passage went deep ahead, and there seemed to be something piled up on the ground in the distance. It's just that the distance is a little far, and the light is not enough, so I can't see clearly. Then he stepped into the passage first, and the rest of the group followed him. He pulled out a shot put-sized iron ball from his bag, placed it on the ground, and made it roll all the way ahead of us, intending to test the mechanism ahead.

"Look at this Situ Feng, it's quite professional!" The jar whispered to me.

"Of course, if you don't be careful, you'll be dead." I said, "So it's true to be careful to sail the ship of 10,000 years." ”

As we approached the pile, we suddenly heard the sound of a jingling bell under our feet, and we seemed to have kicked something made of iron. I looked down with a flashlight and found crossbow arrows more than a foot long all over the ground. Just when we were in doubt, Situ Feng in front beckoned us to step forward. When we came closer, through the gas mask and the flashlight, we finally saw clearly that the things that were blocking the ground were actually the bones of several people.

"Looks like someone came in before us." Situ Feng looked very calm, and carefully examined the corpses and said.

The corpses were dressed in ancient costumes, all coarse cloth, and had no features. All that remains of their bodies is now a handful of dry bones, not even hair. Our idea of distinguishing whether it is a Ming Dynasty or a Qing Dynasty from the hairstyle has also failed. There were some crossbow arrows stuck in their bodies, and it seemed that they had all died from the arrows.

"This ...... This is ......" saw these crossbow arrows, Pu Yifan was very surprised.

"Is this a mechanism?" Ma Xiwen said it directly. As soon as he said this, everyone panicked.

"Don't mess around!" Situ Feng shouted, "This mechanism has failed, if it can still be used, now we are lying on the ground like these dead people!" After listening to Situ Feng's words, everyone gradually calmed down. Think about it, too, how can something that is hundreds of years old still work?

Situ Feng touched the rows of inconspicuous holes in the walls on both sides and said, "Once this mechanism is triggered, more than 100 crossbow arrows will be fired at the same time on both sides of the wall until the machine is exhausted. Although the power is very great, it is a pity that it is a one-off, so since these people have already touched this mechanism, there is no need for us to worry about encountering ten thousand arrows at once. ”

Hearing Situ Feng say this, we were completely relieved.

Ma Xiwen stood up from the corpse and said to Wang Yuesheng and the others: "You have to take pictures and record carefully, these five corpses must have been thieves trying to steal into the underground palace and accidentally trigger the mechanism, so they died here." I just don't know if there's a corpse in front of me......"

Situ Feng shook his head and said, "There should be none, and even if there is, it shouldn't be with them." ”

"How do you know?" Ma Xiwen asked.

Situ Feng turned around and walked a few steps, came to the place where crossbow arrows began to appear on the ground, and said: "The starting point of this mechanism is here, but they died in the middle of the mechanism, which means that there are two possibilities for the trigger point of this mechanism, one trigger point is here where I am standing, which is a delayed trigger, so when they walked to the middle, they were pierced by ten thousand arrows; The other is instant triggering, where the trigger point is right where they fell. However, I'm leaning towards the second option, as I haven't found a trigger here at the moment. But no matter what kind of design is to prevent theft here, but also to catch it all in one place, lest it kill endlessly! ”

After listening to Situ Feng's explanation, we all felt that his analysis was very reasonable, and we couldn't help but nod secretly.

I said to the altar, "See, this tomb robbery is also a technical job, not everyone can do it!" ”

The altar was not convinced: "What kind of technical work?" How many tombs are not just found by two people, carrying hoes and shovels, and digging them in one night? ”

"Isn't that a handful of soil and a mouthful of wood, of course it's easy to say. But those who can steal this kind of tomb with a trap are the masters! I said to the altar, "If this were for the two of us, we might have to leave it here." ”

"That's right. But we can also learn his skills! Tanzi said, "We can't learn how to identify and crack the mechanism, but there is no problem with the iron ball pathfinder." And with my physique, rolling the iron ball forward, it must be farther than that Situ Feng. ”

"You can pull it down!" I said, "If you want the ball to roll far, you have to push harder, and the ball will be faster." This will reduce the amount of time it stays at the trigger point. Don't forget, it takes time for the trap to trigger, and it may roll over before the iron ball can trigger the trap. Therefore, mastering the speed of this rolling iron ball is also a technical job! ”

The corpses that lay out in the passage, we didn't move, we just left them there as they were.
