This iron ladder, with the belief in steel by mankind in the mid-century, is simple in craftsmanship and solid in structure. It is the purest example of pragmatism and does not spend a slight effort on decoration.

If it had been buried elsewhere for more than half a century, it might have been rusted, but this is the Sahara Desert with almost zero air humidity. After erasing the sand, it still looks like it had just been produced from a factory.

When you go deep into the desert, no one will bring extra things, especially this kind of heavy and space-consuming thing.

Zhang Zi'an tapped the steel skeleton with his knuckles. He thought that the aluminum alloy bracket they brought was used to set up a ceiling so that off-road vehicles could avoid exposure to the sun during the day. So, is this iron ladder... Could it be that the same is true?

This seems a bit unreasonable, because using bamboo poles and other things can achieve similar results. Germans are not stupid, so how can they do stupid things?

He was thinking when he suddenly heard Richard making noise: "Gaga! I guessed that the ladder is of course for climbing!"

Isn’t this nonsense? The ladder is not used for climbing, is it used for sitting?

He clearly told it to shut up, but it kept silent. Now Zhang Zian was really angry. He grabbed a handful of sand from the ground and stood up and wanted to stuff it into its mouth.

I saw it flapping its wings and flying high against the pyramid. After flying to a certain position, it closed its wings, but it did not fall like a stone.

What's going on?

Zhang Zi'an and the elves were standing at the foot of the pyramid, looking up. Although the polished golden shell was not a sight to be seen, it was definitely smooth and there was no platform for Richard to stay there.

It turned around, raised its butt outward, and its head and upper body disappeared from everyone's vision.

"There is a hole here. I have always drilled holes whenever I have it, and it can penetrate every hole...Ga!"

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 when he visited the Great Pyramid before, and noticed that there were two so-called "ventilator channels" on the north and south sides of the tomb chamber of the king and the queen's tomb chamber, with a square of 21 cm x 21 cm. It extends to an angle of 45 degrees above the magnitude, and has reached the outside of the wall of the pyramid before stopping, but it has not penetrated through the wall.

What is the "ventilator" used for? There are many different opinions and no consensus, leaving many unsolved mysteries for future generations.

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

Then who opened the ventilation duct?

He looked down at the iron ladder that was still buried in the sand, and the answer was about to come out.

Although Richard is annoying to be noisy all day long, it is not good to leave it alone.

They hadn't seen 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 Zi'an started the drone again and flew to the place where Richard disappeared. Sure enough, he saw a dark hole with irregular gravel remaining on the edge of the hole, probably also being exploded by these German soldiers.

The drone's pickup vaguely captured Richard's cry from afar from the ventilation duct, and it also brought an echo.

After retrieving the drone, Zhang Zi'an went back to the car to get the folding shovel, cleaned the sand, and said, "There's a way."

After a lot of effort, I finally dug out the iron ladder from the sand intact.

The iron ladder is quite heavy in size and its structure is similar to a Russian doll. The small section is nested inside the larger section, and the large section is nested inside the larger section, thus cycling.

When using it, pull out the appropriate length as needed, and fix bolts are provided at the connection between the two sections. After tightening the bolts, the smaller section will not automatically indent into the larger section.

Stable, sturdy, simple and efficient design ideas. From this telescopic iron ladder, you can see the development of the German military industry back then like a leopard.

As for why we don't use lighter aluminum, because the ladder is fully extended and long. For those who climb ladders, no one dares to climb a ladder with a light weight that falls when you touch it. Because of the principle of leverage, the force arms are too long, and even a few strong men are holding it underneath, it is useless. If you should fall down, you can only weigh the ladder itself so that it can stand firmly.

Zhang Zian looked at the height and stretched out most of the iron ladder, then carried it on his shoulder and stood it up, and then put it on the pyramid. This was not his silence, but the iron ladder weighed almost hundreds of pounds, heavy and long, and it was already very powerful to stand it up by one person.

Unfortunately, his estimated height was error-free, which was a bit shorter.

Why not directly pull to the maximum length? It is still a problem with the force arm. The longer the pull, the more difficult it is to stand up the ladder.

He was about to put down the ladder and pull out a piece, and the elves had already understood his intentions.

Fina shouted, "Don't bother! Let go, I'm going up!"

Zhang Zian was blushing and wanted to put down the ladder again. Before he could speak, he felt something was kicking his back and his head was kicked.

He was about to scold someone who was trying to make a fuss. When he looked up, he saw that Fina had already leap high with the force and landed lightly on the pedal about three meters above the ground. Then he jumped again, and every time he crossed the pedal several stages, and in the blink of an eye, he was more than ten meters above the ground.

Its tail stands up like a saber, swinging left and right in the air to maintain body balance.

The pedal is designed for people wearing rubber-soled military boots. The surface has patterns to prevent slippage, but it is not very anti-slip for cats. The iron plate itself is relatively slippery and has a narrow width. It can barely fit when four feet stand up, not to mention that it often jumps up again with its feet a little.

Fina's movements are too thrilling. If she takes a step, she will roll down along the slope of more than 50 degrees in the outer wall of the pyramid. If she is unfortunate, she may continuously bump on the cold and hard iron pedal during the fall...

Even the person who was watching like this was sweating, trying to make a sound to remind it to climb slowly, but he was afraid that it would distract it and cause an accident if it made a sound.

The angle of his head and the other elves raised their heads was getting bigger and bigger. When his neck was sore, Fina stepped on the last pedal, crossed the last distance of nearly two meters, and flew to the position where the hole was like gliding.

ah!

Fina seemed to have misjudged the distance, or was unable to maintain her strength due to continuous high-strength jumps, so she only grabbed the edge of the hole with her two forelimbs and thrust her two hind legs in the air.

"His Majesty!"

The snow lion's face was originally snow-white, and now it was so scared that even the black turtle patterns on its head almost turned white.

Lao Cha moved his body and was about to rush to rescue him.

However, Fina only stayed for a while, and when her physical strength recovered slightly, she turned her waist and disappeared into the ventilation tunnel entrance.
