Miss consul quickly came up with her plan: "Up to 2 days a month, take turns on duty, no rest off is allowed..."

She also has reasons: "The Bell Kingdom in the north also had public holidays. Even before the invasion of the Black Orcs, the public holidays were only 2 days. After the war began, it was reduced to 1 day!"

Black, it's black enough!

Renault was speechless, and it was true that the aliens were even more ruthless against his own.

He can be sure that with the usual methods of Miss Consul, she will probably find a way to arrange half of the people on duty on public holidays, and then the two-day public holiday will quietly shrink to one day...

When he was on earth, the vacation system of single and double holidays made him aggrieved. After quitting, he finally had a double vacation. He was often resentful because of "there is no high-temperature vacation".

In contrast, people on earth are more conscientious.

Renault curled his lips and stopped arguing with the girl. Just 2 days would be 2 days. Just be happy.

I don’t appreciate it if I give you a few more days off, really...

Would you like to mention overtime pay? Forget it, the territories have been expensive recently, so let's talk about it later...

Obviously, his **** decides his head, and he has no money to work overtime before crossing, which will make Renault feel very uncomfortable, but now that he has become a lord, when he thinks of working overtime to pay people, he starts to feel uncomfortable faintly.

At this time, the all-terrain vehicle drove into a rugged grass, and the body suddenly bumped. The girl and Lena quickly grabbed the metal handles on the body, which are the safety devices specially welded by Renault.

The girl soon discovered that the turbulence was much smaller than she expected, and it was not too uncomfortable to sit in the car.

She went out and looked at the ground curiously. Through the lush grass, she suddenly found that the grass was full of big holes and small holes, and the girl was suddenly surprised.

This kind of road...If it were a carriage, it would probably not be able to pass at all, but this weird magical car drove past without difficulty.

At this moment, many questions popped up in the girl's mind.

How could this be?

Is it just because the wheels are slightly bigger and wider?

But why is the vibration amplitude so small? A bigger wheel can't reduce the bumps so much...

The girl took a closer look at the all-terrain vehicle again, only to discover that the car had many different details, not just its smaller size.

Compared with those engineering vehicles, most of its structure was actually made of metal materials, but it was painted with a layer of yellow jellyfish paint. She had no idea at first.

In addition, the tires do not seem to be made of wood. The surface is covered with a strange black material. Many springs are installed on the parts connecting the tires. When the vehicle vibrates, the springs seem to be constantly undulating.

She couldn't help asking, "Renault, what did you put in the car? Why does it feel so smooth?"

Renault smiled slightly: "Springs and tires are the things you just looked at..."

This four-wheeled all-terrain vehicle is the result of Renault playing these days, and the purpose is to verify two brand-new components.

The first is the shock absorption system.

The shock absorption system on earth vehicles consists of springs and shock absorbers.

The spring is easy to say, but the design and manufacture of the shock absorber are too troublesome. It includes a piston structure and a hydraulic system. With the current industrial level, it is simply impossible to handle it.

Of course, it’s not a problem for Renault, but the problem is, you can’t let Lord Lord do everything, right?

So he decisively simplified it into 5 springs, the diameters, materials, and sizes of these springs are different.

The damping effect mainly relies on two of the thicker springs, and the other three thinner springs are responsible for pulling the thick spring and preventing the thick spring from rebounding.

This seems to be without difficulty, but the real difficulty lies not in the design, mainly in the materials.

If the Rune Research Institute did not produce spring steel, Renault would definitely not consider the shock absorption system, isn't it just a little bumpy?

Anyway, the turtles in the different world have thick skin and rough flesh, and they are not bad no matter how hard they are. They are also low-demand and easy to satisfy. As long as they have a car, they will be happy like something. Even if they are thrown up, they may not bear it.

Not at all like the weak chickens on the earth, they are delicate and weak, and it is difficult to wait on them tightly.

As for spring steel, its birth was a wonderful accident.

A few days ago, the newly established material laboratory of the Rune Research Institute, when trial-produced a new alloy, an indigenous apprentice from Odin Island unexpectedly added the snail shell powder of the "black iron snail" by mistake. Kind of alloy being smelted.

This reckless behavior naturally provokes a scolding from the instructor, and then the instructor orders the apprentice to dispose of the "scrapped" material.

However, the unwilling apprentice quietly did a series of tests on the new alloy. He was surprised to find that the performance of the new alloy was unexpectedly good, with its tensile strength and elastic limit far exceeding that of ordinary steel.

This new alloy, which was born by accident, has also become the first major achievement of the materials laboratory. The apprentice who took the feces luck also received a special bonus of 20 silver nar.

Later, even the lord was shocked by this strange thing, and the new alloy also received a name named by the lord himself-spring steel.

Of course, the spring steel of the different world cannot fight the spring steel on the earth. The reason why its elasticity is so excellent is precisely because of the magical conch, the black iron snail.

Just like its name, when the black snail grows, its mantle will secrete a lot of iron in addition to calcium carbonate, and form iron carbonate!

On the earth, iron carbonate can't exist stably, even if it appears, it will be hydrolyzed instantaneously, but in another world, iron carbonate made by black iron snails can exist stably.

The iron carbonate content in the black iron snail shell is extremely high, and almost 40% of the ingredients are iron carbonate.

After the spring steel incident, the materials laboratory deliberately did a lot of tests on the black iron snails. After separating the iron element, the magicians discovered that the density of this iron element is slightly lower than that of normal steel. The isotope that Lord Lord once said.

After testing nearly a hundred formulas with different proportions, the alien siege lions found that the spring steel obtained by mixing ordinary steel with 4% of the new iron isotope has the best overall performance.

The second new part of the all-terrain vehicle is the multilayer solid tire.

The key to this new part is also the material.

The tires on the earth mainly use rubber, but there is no such thing as rubber in the alien world, maybe there is, but it is still hidden in an unmanned corner of this planet, completely unknown.

However, the alien world is a world full of miracles.

When Renault asked the Rune Mage if there was any material that was soft, bulletproof, and could be rubbed **** the ground, all the Rune Mage told him a word in unison.

Nima Gum!

The gelatinous substance extracted from the purpureus purpureus, which is called pancreatic gum, is added with a mineral material called "nima powder", mixed evenly, and after a certain period of smelting, the gray rubber material obtained is Nima Marjiao.

When these rune magicians were still keen on magic dolls, they often used Nima glue to fill the inner cavity of the magic dolls to fix the internal parts.

Nima Glue perfectly meets all the requirements of Lord Lord. It is elastic and soft. Even if you hold a stone and rub it on the Nima Glue surface, you will not see many particles that are worn off.

In addition, its hardness can also be adjusted. The higher the proportion of Nima powder, the higher the hardness, and the abrasion resistance will increase, but the elasticity will decrease, and vice versa.
