Chapter 1274: Climbing

This iron ladder, with the belief in steel in the middle of the last century, has simple craftsmanship and a firm structure. It is the purest example of pragmatism, and no effort has been spent on decoration.

If it had been buried in other places for more than half a century, it might have been corroded, but here is the Sahara Desert with almost zero air humidity. After wiping off the sand, it still looks like it has just been produced in a factory.

When going deep into the desert, no one will take extra things, especially something that is heavy and takes up space.

Zhang Zian tapped the steel frame with his knuckles, thinking that the aluminum alloy bracket they brought was used to set up a canopy to protect the off-road vehicle from the sun during the day, so this iron ladder... Could it be used for the same purpose?

This seems unreasonable, because a similar effect can be achieved with bamboo poles and the like, and the Germans are not stupid, so how could they do something stupid?

He was thinking, when he suddenly heard Richard yelling: "Quack! My uncle guessed it, of course ladders are for climbing!"

Isn't this nonsense? Ladders are not for climbing, are they for sitting?

He clearly told it to shut up, but it refused to change after repeated admonitions. Now Zhang Zian was really annoyed, grabbed a handful of sand from the ground and stood up, trying to stuff it into its mouth.

I saw it fluttering its wings and flying high against the pyramid. After flying to a certain position, it folded its wings, but it didn't fall down like a stone.

what happened?

Zhang Zian and the elves are standing at the foot of the pyramid, looking up. Although the polished golden shell is not very shiny, it is absolutely smooth, and there is no platform for Richard to land on. .

It turned around, pouted its butt outwards, and its head and upper body disappeared from everyone's view.

"There's a hole here. My uncle has always drilled into every hole, and he can get in every hole...Gah!"

With a scream, it suddenly disappeared from there.

Zhang Zian and the other elves were stunned.

Wait a moment!

This is the south side...

He recalled that when he visited the Great Pyramid before, he noticed that there were two so-called "air passages" on the north and south sides of the king's tomb and the queen's tomb. The size was a square of 21 cm by 21 cm, starting from the tomb and extending upward at an angle of 45 degrees. , until it stopped close to the outside of the pyramid wall, but did not penetrate the wall.

There are different opinions on what the "air passage" is used for, and there is no consensus, leaving many unsolved mysteries to future generations.

Could it be...Richard fell into the air duct?

Then who opened the ventilation channel?

He looked down at the iron ladder, still mostly buried in the sand, and the answer was ready.

While it was annoying that Richard was loud all the time, it wasn't good to let it go.

They didn't see the opening of the ventilation duct before, because they were standing at the foot of the pyramid, and their vision was limited when they looked up.

Zhang Zian started the drone again and flew to the location where Richard disappeared, and he saw a dark hole with irregular rubble remaining on the edge of the hole, probably blasted by these German soldiers.

The drone's pickup faintly captured Richard's mournful cry from a distance in the air duct, with echoes.

Taking back the drone, Zhang Zian went back to the car to get the folding shovel, started to clean up the sand, and said, "There is a solution."

After a lot of effort, the iron ladder was finally completely dug out from under the sand.

The weight of the iron ladder is quite heavy, and its structure is similar to a Russian nesting doll. A small section is nested inside a large section, and a large section is nested inside a larger section, so as to circulate.

When in use, pull out an appropriate length as needed, and there are fixed bolts at the connection between the two sections. After the bolts are tightened, the smaller section will not automatically retract into the larger section.

Stable, strong, simple and efficient design ideas, from this retractable iron ladder, you can see the level of development of the German military industry at that time.

As for why not use lighter aluminum, because this ladder is very long when fully extended,

For those who climb ladders, no one dares to climb a ladder that is too light in weight and will fall if touched - due to the principle of leverage, the moment arm is too long, even if a few strong men support it, it is useless, it should fall down , can only make the ladder itself heavy, so that it can stand firmly.

Zhang Zian checked the height with his eyes, stretched out most of the iron ladder, and then used all his strength to lift it up on his shoulders, and then set it up on the pyramid—it was not that he was too weak, but that the iron ladder was almost It weighs over a hundred catties, is heavy and long, and it is already very powerful to be able to stand it up by one person.

It's a pity that his estimated height was wrong, and it was a bit shorter.

Why not just pull to the maximum length? It's still a question of the force arm. The longer the ladder is stretched, the more difficult it is to stand up the ladder.

He was about to put down the ladder and pull it out again, but the elves had already seen his intention.

Fei Na shouted: "Don't bother! Get out of the way, I'm going up!"

Zhang Zian was blushing and wanted to put the ladder down again, but before he could speak, he felt his back being kicked by something, and then his head was also kicked.

He was about to scold who was kicking his nose on his face, but when he looked up, he saw that Fina had jumped high with her strength, and landed lightly on the pedal about three meters away from the ground, and then took off again, every time They have crossed several levels of pedals, and they are already more than ten meters above the ground in the blink of an eye.

Its tail stands up like a saber, and it swings left and right in the air to maintain its balance.

The pedals are designed for people who wear rubber-soled military boots. There are patterns on the surface to prevent slipping, but the anti-slip effect is not great for cats. The iron plate itself is relatively slippery and narrow in width. It can barely accommodate four-legged feet. Often the feet point and jump again.

Fina's movements are too thrilling. If she steps into the air, she will roll down along the 50-degree slope of the outer wall of the pyramid if she is lucky. If she is unlucky, she may continuously bump into the cold and hard iron pedals during the fall...

Even a bystander like him was sweating, wanting to make a sound to remind it to crawl slowly, but he was afraid that making a sound would distract it and cause an accident instead.

He and the other elves raised their heads at an increasing angle, and when their necks were sore, Fina stepped on the last step, crossed the last distance of nearly two meters, and flew towards the entrance of the cave like a glide.

what!

Fina also seemed to have misjudged the distance, or was exhausted due to continuous high-intensity jumps. She only grabbed the edge of the hole with her two forelimbs, and kicked off with her two hind legs.

"His Majesty!"

Snow Lion's face was originally white, but now he was so frightened that even the black tortoise pattern on the top of his head was almost white.

Lao Cha moved and wanted to rush to the rescue.

However, Fina only stayed for a moment, and when her physical strength recovered a little, she rolled over with strength from her waist and disappeared into the ventilation hole.
