?? For Yan Jin's problem, Yan Jin did not stop it, this child who once had a slight autism is now incarnated as a curious baby, and she, who is an older sister, naturally can't hinder her younger brother's learning.

It's just that Yan Jun was not interested in anything about tomb robbery and the like before, but now after listening to what Zhou Shiyang said, he knew that there was actually a big article here, so his interest was particularly strong, and he forgot about the danger for the time being.

Zhou Shiyang actually didn't expect that the content of the popular science he wanted could be understood by this child, but he found that the little guy's eyes flashed with a light of curiosity, and he knew that the other party really understood, and he felt a sense of accomplishment inexplicably, so he also came to nature, and continued the topic just now.

Zhou Shiyang was worried that Yan Jun would not understand, and this kind of mechanism was indeed very tricky, so he squatted directly on the ground, found a stone, and started to explain the scene.

"In fact, the principle of construction of this kind of cemetery is not difficult to understand, that is, in the early stage of construction, according to the size of the cemetery determined by Kanyu, dig out a deep enough, large enough underground space, some cemeteries are more than ten meters deep, the area is more than ten square meters, and more powerful will dig hundreds of square meters of underground space. After determining the direction and orientation of the coffin, after the coffin is buried in it, it is not backfilled with soil as we generally know, but buried with fried fine sand. Wait until the sand is sufficiently positioned and thick to cover it with earth and tamp all sides of the tomb. ”

"But Brother Zhou, why do you have to fry the sand dry? Is there anything special about this? Yan Jun felt that he had asked the key to this anti-theft method.

Zhou Shiyang nodded, "Because if there is moisture in the sand, it is not conducive to the fluidity of the sand. The dry fine sand is like water, and it is extremely fluid, and the tomb robbers cannot dig the robbery hole at all, because when digging, the sand will flow, and it will not form a robbery hole at all. Even if it is dug up, once the tomb robbers enter it, it is very likely to cause a landslide and make them martyrs. The number of grave robbers who died in such tombs is staggering. ”

I see, Yan Jun nodded, "Then there are stones in the sand, is it to let the sand flow and drive the stones?" ”

"Yes, the stone was built to kill the tomb robbers, and after the top floor of the tomb collapsed, a large amount of sand and stone were piled up in the coffin, which effectively prevented theft. According to our research and understanding, these stones used as anti-theft methods are specially mined and carefully selected, and the weight and size of the stones are irregular. These stones have a variety of colors and shapes, but they all have a common feature, that is, the corners are very sharp, and they cannot be prevented, which can be said to play the role of a 'hidden weapon'. So when we enter this Ming Tomb, we must pay more attention, I can't confirm whether there is such a mechanism in this tomb, if there is, the danger factor will be greatly increased, you must pay attention to it. ”

Once you trigger a trap that shouldn't be triggered, you're going to be buried alive.

After introducing this method, Zhou Shiyang found that everyone's expressions became very solemn, but there were other methods in the back, and he had to make it clear to everyone before entering, so as not to delay someone in the process of entering.

"If the sand or stone graveyard is something that slowly traps you into it and can't extricate yourself, the type of mechanism I'm going to introduce next is the type of mechanism that quickly kills people and actively attacks. This is the fourth: the crossbow hanging sword. ”

Hearing Zhou Shiyang's words, Yan Jin immediately felt that Mu Yuexuan, the fourth daughter-in-law on the side, seemed to be very interested, "Xiaoxuan, you seem to be very happy?" ”

"No, no," Mu Yuexuan hurriedly waved her hand, "I'm just more interested in ancient weapons." ”

Because Mu Yuexuan has not joined the Holy Northern League for a long time, she has been with Yan Jian for a short time, although everyone admires this sister-in-law, but she still feels a little pressure inexplicably.

I see, Yan Jin nodded, "Then after entering the cemetery, if you find a suitable weapon, we will keep it for you, and if you are fine, you can take a look and treat it as a hobby." ”

Originally, Yan Jin didn't think about taking Mu Yuexuan in, but later she brought it because she was very knowledgeable and well-informed, and maybe there would be other gains in the mausoleum.

After all, entering the tomb of an emperor who has never been successfully patronized by tomb robbers is estimated to have risks and opportunities coexisting, and Yan Jin herself does not expect her to make much contribution to the team, but she will not despise her, because she is the daughter-in-law of the fourth child, and she is the fourth brother and sister handpicked by her husband Yue Stygian.

Hearing Yan Jin's words, Mu Yuexuan felt a warmth in her heart, and she could see that Yan Jin said this very normally and naturally, as if she was talking about a very simple matter.

"The fourth anti-tomb method, among all the anti-tomb robbery methods, is the most mysterious. The crossbow is an arrow, and the 'Fu crossbow' is an anti-theft collection mechanism that can automatically fire sharp arrows along the way in the place where tomb robbers must pass, and is secretly located in the dead pit of the mausoleum, as long as it is triggered by a certain trigger. If it is because of the difficulty of construction, ordinary people can't afford it, then this kind of erection of this kind of organ is generally only used in high mausoleums such as imperial tombs, money, where does the bow and arrow come from without money? This kind of thing pursues quantity, ordinary people can't afford it at all, and for rulers, ordinary people are not allowed to have so many bows and crossbows, so what's the difference between that and preparing for rebellion. ”

After Zhou Shiyang finished speaking, he smiled bitterly, "Legend, of course, this is just a legend, because the mausoleum of Qin Shi Huang has really not been entered so far, and it is said that there is a 'Fu crossbow' in his mausoleum." In order to prevent future generations from digging up his grave, the First Emperor ordered craftsmen to set up a number of crossbows and shoot those who tried to enter the tomb. The authenticity of this legend needs to be verified, because until the end of the world, there was no clear record of this kind of ancient tomb mechanism in all the archaeological reports of the Huaxia Kingdom. So we wait for the Ming Xiaoling Mausoleum to go in, whether there is really such a mechanism in it, I can't guarantee. After all, an archaeologist once said that the way to shoot the diggers with a machine shot epitomizes the highest level of mechanical design ideas and mechanical production techniques of each dynasty at that time. ”
