"Xiaodu Song~ How's it going, is it beautiful?"

Melissa, dressed in a gorgeous lolita and black animal skin heels, spun around. The pen ~ fun ~ pavilion www.biquge.info long skirt full of satin and bows floated. Since Du Ge took out the clothes to make pictures, the first clothes made by the textile factory must have entered Melissa's wardrobe, and the wardrobe in her bedroom has expanded from 3 to 7.

"Uh-huh, pretty, very pretty. ”

How dare Duge not be beautiful in the club, I remember saying it straight for the first time. was caught by Melissa and pinched in her arms for an hour of heart-to-heart communication, and Duge's cheeks and ears were pinched red.

"Queen Melissa, what did you call me to do? ”

In the morning, Duge was notified that Melissa was looking for him.

Melissa didn't answer immediately, but sat on the sofa and looked at Duge with a smile.

Seeing her like this, Du Ge sighed, consciously walked over, and sat on Melissa's long full and round legs. Then Melissa put her arms around him intimately, which was basically the standard position for the two of them to chat.

"It's a problem with the carpenter's factory, some time ago the carpenter produced furniture, using wood that the tribe had stockpiled for many years. During this time, the tribe built houses and produced furniture, and the inventory of the tribe for more than ten years was almost bottomed out. ”

Melissa said this, and Duge immediately understood.

Without any tools, cutting down trees can be a physically demanding and time-consuming task. And now the fox clan lacks manpower and time the most.

"yes, I see. ”

"I'm not done!" Melissa muttered, pinching her and muttering.

"Isn't it just tired of cutting trees?"

“…… Alas, every time I didn't say it you guessed. ”

"I have a way to do this, but the wolf clan hasn't sent iron ore yet. It can only be used by the coppersmiths of the military department. ”

"Well, I'll write you a warrant. ”

After a while, Duge took Melissa's warrant to the military headquarters. Although the cannibalistic eyes of the military sisters looked at him, Duge threw Melissa the warrant, and people had to be obedient.

He pulled out a grinding tool, a simple smooth arc. The craftsmen were ordered to use this mold to make thin copper arc-shaped sheets, requiring that the arc should not be out of shape, and the surface should be polished smooth. Once these curved sheets are made, they can be connected to each other to form a long, long, semi-cylindrical structure.

As for why Duge did this, it was to make a solar focusing magic machine.

The energy that drives any movement on the planet's surface comes from the sun. Whether it's water currents, wind, or carbon from deep vegetation. Their potential energy and internal energy are converted through sunlight energy.

Turning over the development of magic pattern technology and seeing this black technology, Du Ge sighed at the similarity of the process of civilization development.

This solar energy focusing magic energy machine is one of the earliest energy sources developed, but due to the development and utilization of magic crystal energy, the solar device has been suspended due to high prices, difficult storage and other shortcomings. After the magic pattern technology has developed to a certain point, it will be restarted.

There was a similar development in the mechanical civilization of the first Duge. On the eve of the First World War, there was research on solar energy, which used arcs to concentrate sunlight, evaporated water and steam to push pistons, and could make ice in hot summers. It's just that coal is cheap and has a wide range of use, so it had to be eliminated. Later, after the development of science and technology, solar energy began to be used again.

When it comes to the refrigerator, Duge has already put it on the agenda.

The principle of mechanical technology refrigerator is not complicated, it uses the role of evaporation cooling and gasification heat absorption, through continuous compression of gas, so that it is gasified and liquefied, and exothermic heat absorption achieves the refrigeration effect. It's just that the source of the refrigerant is a problem.

I don't plan to use a mechanical technology refrigerator because the magic pattern technology has a bug, which can be called the magic pattern of the 'temperature diode'. It's a natural refrigerator, just make a box and carve a single line of thermal conductive magic patterns. Add some small devices and you can make a refrigerator.

It's a long way off, back to the solar focusing magic machine.

Because the junior Demon Pattern artist did not return, the simple answer Demon Pattern Song carved it himself, and the complex internal core Song was purchased directly from the system. The device, which is 10 meters long and 3 meters wide, can gather solar energy. Convert sunlight into magical energy, but there is no storage device, and without sunlight, these magical energies will disappear.

This device is only the energy base, and the fox clan does not have magic crystal ore first, so they can only use these cost-effective solar devices as a temporary energy source.

And then there's the big one, the big chainsaw!

That's right, it's a chainsaw! No, it's supposed to be a magic saw.

The only thing that saves manpower is machinery, and there is a magic pattern in the magic energy transmission device that converts magic energy into mechanical force, which makes magic energy sawing possible. Careful and precise magic energy mechanical song can't be made, so now directly enlarge the magic energy saw.

When connected to the magic machine, the oversized timbercutter is complete.

The heavy physical work of cutting down trees or something will naturally be solved.

In addition to cutting trees, this oversized magic saw can also be used for stone cutting. It's just complicated, and the fox clan is very troublesome to make. So Du Ge put part of his mind on the use of water power. Hydrodynamics can be said to be the earliest energy used by human beings, a constantly flowing water source. From high to low, it reserves a large amount of potential energy, and as long as a small part is extracted, it is enough for human use.

Therefore, while developing the magic saw, Duge also put the water power unit on the agenda. Prepare for a big project.

Large pumping machine with draft access throughout the drainage.

This is a purely mechanical design, using a water wheel to use the potential energy of the water flow itself to send water into the upper floors. It's the top of the tribe. Then let go of the canal and let the water pumped by the pump be left at all levels of the tribe, so as to solve the original manpower to carry water and release labor.

At the same time, the large water flow down, Duge can use the water wheel to use the water power wherever it is needed.

Such as hydraulic hammers, mills, etc. The hydraulic hammer can be used in the future to strike iron, which is physically demanding, and Duge's preparation for assembly line production consumes physical energy. With a hydraulic hammer, not only can the efficiency be greatly improved, but also the manpower can be liberated, which is the best of both worlds.

Du Ge was busy between training soldiers and preparing for the construction of the tribe during the day, and accompanied five loli at night. The days flew by like this.

There was one thing that made him feel a pain in the egg.,The blueprints of those clothes he took out,Design and sew all kinds of beautiful clothes to five Lori.。 What sailor suits, lolitas, lace miniskirts, pleated skirts, etc., make him feel out of time.

For example, now, Lilina who was pressed by him on the bed in a sailor suit, desperately waving her little paws and struggling.

"Let go of Princess Ben!, don't do those things with stinky men!" (To be continued.) )
