Regardless of the entire Middle-earth, or the Magic Continent and the Knight Federation, except for the Jingwei, the laboratory that Donner built in the Stone Villa is an existence that is ahead of its time. Pen, fun, and www.biquge.info

Here, there are a complete set of precision machine tools that have been processed and polished by the most skilled dwarf craftsmen for several years, all kinds of high-purity chemicals trial-produced by the Misty Chemical Engineering Institute, and various colored metals shipped from the country of the Far North.

More important than all this, however, is a biochip on the back of the lab's owner's spine. It is because of this chip that all of Downer's experiments and designs are almost perfect, and it is precisely because of this chip that the Fog City factory will have the scale it has today.

If Donner had been aware of the Doctor's plans and wary of the Jingwei when he first entered the Jingwei, he would most likely have refused to implant the chip. But in fact, when he learned about his situation from the fragmentary hints left by the doctor, the chip had long since merged with him.

Donner didn't know it at first, but now he has no choice. The computing power of this chip is like an addiction that is hard to quit, and no matter how decisive he is, Donner cannot refuse its temptation - not to mention that he does not have the ability to get rid of it.

In the lab, time has passed for no longer - interestingly, the chip that Donner implanted is unimaginably powerful, but it does not have the most basic timekeeping function - on the workbench in front of Donner, twenty-six secret copper pillars are neatly erected.

Unlike the first seven pillars, although the length of these secret bronze pillars remains the same, the diameter is several times thinner, almost only slightly thicker than chopsticks, and there are no traces of totemic patterns on the surface.

Donner's experiment went surprisingly well, but the results still puzzled him.

First of all, as Austin said, when the secret copper is pressed, the totemic pattern on the surface will magically disappear - according to Donner's calculation, it should be squeezed into the extra dimension, similar to pushing a piece of paper on a tabletop and the piece of paper will be squeezed into the third dimension. The only difference is that the piece of paper enters the third dimension without any blockage, while the Mitri Copper enters the extra dimension and needs to overcome the traction of the three-dimensional membrane.

This traction is what Downer calls the membrane resistance effect, i.e., the tendency of a realistic three-dimensional membrane to confine matter to the membrane, just as water droplets on a soap bubble are confined to a soap bubble.

According to Donner's previous experiments, the film resistance effect of various microscopic substances is different, and the film resistance effect of most non-metals is so large that it is almost completely confined to the three-dimensional film, while the film resistance effect of various metals is different.

In fact, a series of experiments conducted by Donner at the Misty Chemical Engineering Institute have given a possible explanation for this phenomenon.

When using the difference in the melting point of different components in the air, the air is liquefied at high pressure and low temperature to separate the various gases, and no inert gas is found. That is, noble gases (i.e., monoatomic molecules) may not exist in this world.

Then, in connection with the phenomenon that the metal film resistance effect is small, it is easy to infer that the three-dimensional film cannot limit the monoatomic molecules - although the metal is not a monoatomic molecule, it is also directly composed of atoms in the microscopic state, and the difference with noble gas is that the metal atoms are not isolated, and there are metal bonds between them.

The explanation of these microscopic phenomena requires the development of physics beyond the level of the earth to be done, so Donner only had a vague guess and did not spend any more time on it.

And the current experiment to verify the role of the dwarf totem is obviously more realistic.

In the experiment, Donner made seventeen secret bronze pillars, and found the dwarf totems corresponding to the five magic gold of water, fire, wind, earth, and wood, but then made nine secret bronze pillars, and he did not find any connection between the other two dwarf totems and the magic marrow.

Moreover, the characteristics shown by the five-line dwarf totem also made him temporarily give up trying to continue. Because, in addition to the fire totem pole burning red and the water totem pole emitting a whole cold air, the other three totem poles are just a little warm and have no magic.

Although the results of the experiment were not satisfactory, and five of the seven dwarven totems were not found to be of practical significance, Donner was not disappointed at all.

On the contrary, the change in the fire system totem pole alone had already made him ecstatic.

As one of the most common metals in the secret realm, the melting point of secret copper is about 1,100 degrees, which can make it reach a red-hot state, and the temperature is at least between 500°C-800°C.

To prove this, not long after Downer finished making this fire totem pole, he immersed it in a metal tank about a cubic size, filled with clean water, and after only twenty minutes, the water boiled.

As Donner continued to experiment and match, the water had been boiling, and if it weren't for the existence of the Condensate Circle, the entire laboratory would have been filled with steam.

At this point, the energy problem that had bound Donner for ten years was solved, and the magical elements throughout Middle-earth were no longer just a means of magic, but would become a helping force to propel the world up the ladder of civilization.

Supposedly, at this point, Donner should have been content to stop the experiment, but he still sat down in front of the test bench after making the twenty-six secret bronze pillars.

After sitting for about three or five minutes, he got up and took a blank piece of paper, and drew a long curve with a quill. Immediately after that, the patterns on the white paper became more and more complex, and various numbers were marked down from time to time.

Less than half an hour later, Donner stood up and left a finished mechanical drawing on his desk.

In this world, no one can read this drawing, but if you put it on the earth, there may be many people who can recognize the content of the drawing.

Because this is a famous rotary engine!

No, it should probably be said that it is very much like a rotary engine, except that there are no spark plugs in this engine, and instead there are complex heat diversion signs.

The triangular rotor edge motion trajectory drawn by the dotted line outlines the outline of the engine compartment, outside the cabin, there are two air chambers, which represent hot and cold air with red and blue respectively, and in the process of rotor operation, two kinds of air with great temperature difference are introduced into the cabin in turn, and then the thermal expansion and cold contraction effect is used to continuously push or attract the rotor, so that it rotates around a group of planetary gears and closely follows the bulkhead wall of the engine.

Similar rotary engines were once famous on the earth for their small size, low noise and simple structure, but finally they were completely replaced by piston engines because of their easy wear, difficult maintenance and high energy consumption.

However, the shortcomings of the rotary engine can be compensated for by the characteristics of the metal materials of this world, and its many advantages are all retained.

It was for this reason that the rotor engine became the structural prototype of the first magic machine in Donner's hands.
