Behind me is the entire history of mankind!

Chapter 39: Block Game
This is a rotary arm crane with an inclined cantilever and a block of pulleys on the top of the arm, which can be lifted and rotated. In theory, it can lift a weight of six thousand kilograms, and it is very labor-saving. It can be lifted with only manpower. stand up.

But after all, it uses manpower, and the work efficiency is always unsatisfactory, and it is only used in the transitional stage.

"This" showed a bit of perplexity from the beginning to the end, "Do you have any tools? It's the kind of tool for cutting wood."

"You don't have to worry about this. I will help you with all the parts. You only need to be responsible for assembling it. After assembling this machine, I will give you five points of military merit." Da Vinci said.

Dazed from beginning to end, then he patted his chest, "No problem! Just leave it to me!"

"How do you make parts?" Nan Sheng asked curiously from the side.

Da Vinci didn't say a word, but walked to the wood pile silently and touched the wood. He was not only playing with wood during this time, but also spent time learning in the Prometheus system. At least he can spell water molecules.

A faint light flashed on his hands, and he gradually touched these pieces of wood. In the UI projection in front of his eyes, the shape of the wood appeared. When he clicked on the secondary interface, the molecular composition of the wood appeared. There are still many ingredients in it.

It mainly contains carbohydrates, that is, fiber.It also contains starch, protein, water, mineral ions and some rare elements.

Specifically, there are aliphatic compounds, including fatty alcohols, and fatty acids in the form of their glycerides.

After hydrolysis with caustic soda, sodium salts of high-carbon fatty acids (sodium soap, that is, ordinary soap) and glycerin can be produced. The glycerin used by Mendeleev to make nitroglycerin explosives is extracted from these plants.

There are also sugars (including starch) and pectin, which mainly exist in parenchyma cells; terpenoids, including volatile oils and resin acids, such as turpentine, mainly exist in resin ducts;

Phenolic compounds, including tannins, flavonoids, and woody phenols, are mainly found in bark and heartwood.

In addition, there are some very trace elements. Click again and there is a third-level interface, which contains the atomic composition of this tree, carbon 48%, hydrogen 6%, oxygen 45%, nitrogen 0.1%...

Looking at those interfaces, even college students will have a headache for a while, the micro world is not at all simpler than the macro world.

This is also the reason why ether particles need to be used by advanced intellectuals.

The substance separation technology of ether particles is very rough and directly extracts a certain substance from it, without changing the internal properties of the wood after it is normally dried with moisture.

Such as normal thermal expansion and contraction changes.

Mendeleev had tried before to get all the moisture out of the wood.

Eventually, the restructured wood becomes extremely fragile due to the sudden disappearance of internal moisture.

Therefore, after part of the water is extracted, the position of the remaining molecules needs to be changed.

This is the same as that kind of building block game, where a pile of building blocks is stacked to form a building, and each person draws one piece in one round, and each time a piece is drawn, the structure of the building block building has a slight risk of collapse.

This is very troublesome, the possibility of ether particles is huge, but behind them may represent a nearly brand-new physical system and chemical system, which requires a lot of research and effort.

For example, the work of extracting water molecules is very small. There may be hundreds of millions of water molecules in this tree. It is definitely not a job that can be done by one person. Therefore, the power of computers is needed.

Each separation and reorganization requires editing of the corresponding program.

These days Mendeleev is still working on how to use ether particles to directly turn limestone into cement.

However, after a series of experiments, I finally chose to use a stove to fire.

Because that is a ready-made method that has experienced countless successes, it is not meaningful to spend energy to study ether particles, and the cost is too high.

After discussion, the scientists agreed that there is no need to add ether particles to the existing industrial system.

In addition to spending unnecessary energy to study the already mature results, if it is applied to these industries from the perspective of the formation of ether particles.

Then the animals in this world may suffer a catastrophe.

Ether particles should be used as a tool for more advanced scientific and technological breakthroughs, such as cold nuclear fusion, such as other quantum technologies.

Or, when the early industrial system is not perfect, take a shortcut.

However, it is not difficult for Da Vinci. He has learned this operation not long ago. Under his operation, water molecules are separated, and the molecular structure of wood is reconstructed. At the same time, in the first interface, Finch reconstructs parts of the crane.

After about a few minutes, under the incredible eyes of Nan Sheng and the surrounding players.

Those few pieces of wood turned into several long pieces of wood, as well as some gears and wooden pulleys, and none of the wood was wasted.

The remaining leftovers were made into a wooden bunny by Da Vinci, and then casually threw it to Nan Sheng.

"Here it is for you, little one."

Nan Sheng hurriedly took the little rabbit, looked at the pile of parts, and then at the rabbit in his hand, with a dazed look on his face.

what just happened?
……

"You want to turn this hub into a bit?"

At the same time, on the other side, Jiang Ye, who was standing next to the cement furnace, asked Brother Li and the others.

Brother Li nodded.

"The two stoves are working now, so I guess you won't be able to use them." Jiang Ye looked at the stove and said, "But."

Jiang Ye paused, "Send me the picture of the bit."

"You know how to blacksmith?" Brother Li said in surprise.

"Give me the materials." Looking at the picture, Jiang Ye said.

Jie Se quickly handed Jiang Ye the wheel hub he changed from the fisherman, but the aquatic plants on it had basically been removed.

Jiang Ye looked at the hub, "Aluminum alloy? Good stuff, where did you get it?"

"The fishing team caught it." Li Ge said.

"It's not surprising." Jiang Ye nodded, "However, this thing is probably not suitable for a horse bit in the mouth. After all, it contains aluminum, which will affect the brain after a long time. I will use my knife to forge one for you."

As he said that, he took out a machete from his waist, which was distributed in the previous mission. Jiang Ye bought it with the military merit he earned, so it belonged to him.

I saw that he did not put the knife into the furnace to be calcined, nor did he pick up the hammer, but just stretched out his hand to touch the knife, and then, the blue light shone from his hand, and gradually, the machete was disintegrated. Under the shocked eyes of the three, the machete turned into a metal horse bit.

"Fuck!"

"Fuck!"

"Fuck!"

Jiang Ye turned his head and smiled at the three of them, his white teeth reflecting the sunlight.

"I call it..."

"……alchemy."

Da Vinci looked at Nan Sheng and smiled.

"Alchemy!?"

Nan Sheng opened her eyes slightly, but after a brief shock, she quickly accepted it all.

After all, this is the game world, everything is possible.

In this case, this game world may not be an ordinary sandbox game, but also has a fantasy background.

"You can start the installation. In a few hours, it will be dark. We need to build the first part of the city wall within a few hours."

He came back to his senses from the beginning to the end, and then looked to one side, he complained, "I finally know why the basalt brought back is in this shape."

The basalts piled up not far away are basically square in shape, smooth and tidy, and can be assembled directly like building blocks. So far, they have not been able to mass-produce explosives, and can only use ether particles to directly decompose the basalt wall.

In order to save resources, it is the best choice to make this kind of block suitable for assembly when dismantling and mining.

"Come on a few people, put this thing together with me!" shouted from beginning to end.

Several players who were digging the foundation echoed, put down their work, and assembled the crane together from the beginning to the end.

Da Vinci, on the other hand, was holding a blueprint and continued to sketch something, while Nan Sheng looked closer curiously, seeing the strange patterns on it, like a city wall but not a city wall, which made Nan Sheng wrinkle slightly He frowned, a little puzzled.

"What is this?"
