In fact, Zhang Nan was a little braggart just now, saying that he wanted to use the methods that the ancient Egyptians could use to remove the stone slabs: his method was available to the ancient Egyptians, but it is difficult to say whether the Pharaoh of the ancient kingdom Snifru would have it.

Of course, the question only arises in the question of whether the technology has appeared, and in terms of materials and actual operability, not to mention ancient Egypt 4,600 years ago, the Chinese people in the era of the cave people on the top of the mountain can also be handled.

Among them, this battering ram is the key!

The first time a battering ram appeared in recorded history was in ancient Egypt, but it was just over 3,500 years after the end of the Second Intermediate Period after the Egyptians freed themselves from Hyksos rule and at the beginning of the New Dynastic Era.

As for whether ancient Egypt or other ancient civilizations in the world had a battering ram earlier, I really don't know, Zhang Nan thinks that there should be, because this thing has a simple structure, but it is not recorded.

It's simple, when the battering ram first appeared, it was just a tree trunk, and it is unknown whether it contains a metal head, and it is estimated that it is unlikely, because Egypt is not a place to produce goats.

What is the relationship between battering rams and goats?

Because in many ancient Western languages, battering ram and male goat and goat have always been the same word, from a linguistic point of view, the place where the battering ram was named must have been in a place rich in goats.

So where will it be?

Probably Assyria, a name that once terrified the two rivers and Persia.

The greatest contribution of the Assyrians to mankind was the art of war, and its politics, economy, and culture all had strong military overtones. Almost all of the reliefs left behind in the Assyrian period are related to military affairs, and from the perspective of the Western world, the national mobilization, militarism, division of labor and grouping, mobile warfare, engineering baggage, various breakthroughs, etc., are all the creations of the Assyrians.

By the way, everything west of China can be called the West.

In a relief depicting the Assyrian army attacking a city, a chariot equipped with a battering ram crashes into an enemy adobe wall, and on the head of this battering ram is a metal ram's head, typical of Western-style battering rams.

Probably because the ram likes to use its horns to hit the east and west, and this image is just right for the battering ram.

The Assyrians could use metal, but the ancient Egyptians did not have enough metal, so it is estimated that they could only use tree trunks alone.

Zhang Nan wants to make a battering ram, or the kind used by the ancient Egyptians, which must have wood - this is a desert area, and there is not much wood!

Fortunately, Zhang Nan's requirements for wood are not particularly high, and the battering ram he made is obviously pocket-sized, and he can't use the giant wood of the city gate.

But after turning the construction site around, there are still two most important pieces of wood missing.

There was a guy who knew Arabic in the security contractor, and he called.

"Go to Dekhshur, there should be a market for building materials. I need two logs, one of which is more than 2.5 meters long and can withstand at least 15 tons of vertical pressure. Don't be too thick, if you want two people to move, the stronger the appointment.

The other one should not be more than 2 meters long, but it should weigh between 80 and 100 kilograms.

If there is a woodwork room over there, ask them to process 20 log sticks with a diameter of 5 cm and a length of 20 cm at once, just plain hardwood.

If not, get a few sturdy logs of about the same diameter that we can cut. ”

The vertical compression resistance is 15 tons, not 15 tons horizontally, it doesn't need to be thick, and it is very easy to find a suitable one under the standard that two people can carry away. And many Egyptians will build houses with relatives and friends, and there are many places where logs are used, which can be bought by Dekhshur.

Sure enough, after a while, someone drove back to report: there is one over there, but it takes some time for the car stick.

Don't worry, Zhang Nan also has a bit of manual work here.

An hour later, the two buddies who had bought something came back.

Here Zhang Nan has already found other supporting timber, also cut the length, and then cut the two newly bought logs according to Zhang Nan's requirements, which is ready to start!

A long and short push of wood, a group of people carried, carried, and carried into the pyramid, and a pile of sacks of sandbags, and Sanchez and old Zamorano also carried two bundles of rope and lead wire - ancient Egypt did not have lead wire, in fact, this would be the same with hemp rope, but suddenly I couldn't find the right thickness of hemp rope, so I simply replaced it with thin lead wire, which is not cheating.

When they arrived at the "fake burial chamber", they first tied eight arm-thick logs and a few short logs into two quadrupods with lead wire, and then tied a slightly thicker log to the top as a longitudinal beam

The 85-kilogram log was hung from a stringer with two sections of hemp rope and a pocket-sized battering ram.

William had already led someone to remove the excess plaster around the zenith, and he could see the tiny gap between the huge stone slab above and the top of the wall - there was no danger inside, because Qiu Bo had done a test when the plaster had just been removed.

It can be measured if there is a gap, although it is extremely narrow, but the sensitivity of the detector is high enough: there is a little lack of oxygen on the top, and there are no special toxic substances.

This will everyone already understand what Zhang Nan is going to do, this is definitely a way that an ancient Egyptian 4,600 years ago could do!

The log, which looked like it could withstand at least a few dozen tons of weight, was erected diagonally against the wall - it couldn't be upright, because it grew almost 10 centimeters higher than the height of the burial chamber.

The battering ram was angled, and the sandbags were placed under the quad to prevent it from "running too much".

After the preparations were done, Zhang Nan pointed to a few strong men, "Press the shelf so as not to fly!"

This will even be there for the Mark brothers, and there will be no shortage of large-tonnage human sandbags. With the addition of Jin Wenbo and Ma Wei, this crushes the battering ram to death!

Li Panfeng and Qiu Bo held the logs in front of them, which were erected slightly diagonally against a corner of the zenith - for insurance, there were sandbags at each end of the bottom of the log.

Zhang Nan walked behind the battering ram and took aim, which was swinging and hitting the wood with Tu Haibo and the others.

At first, it was only slightly forced, not much force, and let it swing back and forth first. When it feels like it's about the same, shout the number and push hard!

With a "bang", the head of the wood smashed right at the bottom of the erected log: at this moment, a puff of dust fell from the gaps that were separated around the top of the burial chamber - the bottom of the wood was knocked inward!

I feel that the impact point is accurate, and go on!

There was another "bang", and Charlize Theron, who was watching the excitement on the side, excitedly pointed to the top of the log and said loudly: "It's up, it's up!"

Of course, it would be lifted up, and under the successive blows of the battering ram, the erected log was soon perpendicular to the wall against it, and the huge stone slab on top was held up at a corner, and there was a gap with the top of the tomb wall, up to 10 centimeters.

It's time to get the prepared log rollers below.
