The consul lady quickly came up with her own plan: "two days at most in a month, on duty in turn, no compensatory leave is allowed..."

    She also has a reason: "in those days, bell kingdom in the north also had a public holiday. Even before the invasion of the black orcs, the public holiday was only two days. After the war started, it was reduced to one day!"

    Black, that''s black!

    Renault is speechless. As expected, people from other countries are more cruel to their own people.

    He can be sure that, by the way that Miss consul always used to do, she would try to arrange half the people on duty on public holidays, and then the two-day public holiday would be quietly reduced to one day

    When he was on the earth, he was indignant at the system of single and double vacation. After he changed his job, he finally had double vacation. He was often indignant because of "no high temperature vacation".

    In contrast, people on earth have more conscience.

    Renault curled his lips, no longer with girls to continue the theory, two days on two days, you are happy.

    It''s ungrateful to give you a few more days off

    Do you want to talk about overtime pay? Forget it. The territory has been spending a lot recently. Let''s talk about it later

    Obviously, the bottom decides the head. Renault will feel very uncomfortable if he doesn''t have money to work overtime before crossing. But now when he becomes the Lord, he starts to feel uncomfortable when he thinks of paying people overtime.

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

    The girl soon found that the bumpiness was much smaller than she expected, and she didn''t feel very uncomfortable sitting in the car.

    She went out and looked at the ground curiously. Through the lush grass leaves, she was surprised to find that the grass was full of big holes and small holes.

    This road If it''s a carriage, I''m afraid it won''t be able to pass at all, but this strange magic bullet train has no difficulty in passing.

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

    How could that be?

    Is it just because the wheels are a little bigger and wider?

    But why is the vibration so small? If the wheels are bigger, they can''t reduce the bumps so much

    The girl carefully observed the all terrain vehicle again, and then found that there were many different details of the vehicle, not just the smaller size.

    Compared with those engineering vehicles, most of their structures were made of metal materials, but they were painted with a layer of yellow jellyfish paint. She had no idea at first.

    In addition, it seems that the tire is not made of wood. The surface is covered with a strange layer of black material. Many springs are installed on the parts connecting the tire. When the vehicle vibrates, the springs seem to fluctuate up and down.

    She couldn''t help asking, "Renault, what do you have in your car? Why does it feel so smooth? "

    Renault smiles: "the spring, the tire, is what you just looked at..."

    This four-wheel all terrain vehicle is just the result of Renault''s playing these days. Its purpose is to verify two new components.

    The first is shock absorption system.

    The shock absorption system of earth vehicle is composed of spring and shock absorber.

    The spring is easy to say, but the design and manufacture of shock absorber are too troublesome. It includes piston structure and a set of hydraulic system. It is impossible to make it at present industrial level.

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

    So he decisively simplified it into five springs with different diameters, materials and sizes,

    the shock absorption effect mainly depends on two of the thicker springs, and the other three thinner springs are responsible for pulling the thick spring to prevent the spring from jumping back.

    This seems to be no difficulty, but the real difficulty is not in the design, mainly in the materials.

    If Rune didn''t come up with spring steel, Renault would never consider the damping system. Isn''t it just a little bumpy?

    anyway, woodlouse is thick and rough, so it is not bad to be on the top. It also requires low and easy to satisfy. As long as they have a car, they are happy what they are like. Even if they are puking up, I am afraid they will not be reluctant to come down.

    It''s not like the weak chickens on the earth. They are delicate and weak and hard to serve.

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

    A few days ago, when the newly established Materials Laboratory of Rune Research Institute was trying to produce a new alloy, an Aboriginal apprentice from Odin unexpectedly added the shell powder of "black iron snail" into a melting alloy by mistake.

    This kind of reckless behavior naturally attracted a scolding from the tutor, and then the tutor ordered the apprentice to dispose of this furnace of "scrap" materials.

    However, the indomitable apprentice quietly did a series of tests on the new alloy, and he was surprised to find that the performance of the new alloy was surprisingly good, and the tensile strength and elastic limit of the new alloy were far superior to those of ordinary steel.

    The new alloy, which was born by mistake, also became the first major achievement of the materials laboratory. The apprentice, who was lucky enough, also received a special bonus of 20 Silver nals.Later, even the LORD was shocked by this wonderful event, and the new alloy was named spring steel by the Lord himself.

    Of course, the alien spring steel can''t compete with the earth''s spring steel. The reason why its elasticity is so good is that the black iron snail is such a magical conch.

    Just like its name, when the snail grows, its mantle not only secretes calcium carbonate, but also secretes a lot of iron and forms iron carbonate!

    On earth, iron carbonate can''t exist stably at all. Even if it appears, it will hydrolyze instantly. But in the alien world, iron carbonate made by black iron snail can exist stably.

    The content of iron carbonate in black iron shell is very high, almost 40% of which is iron carbonate.

    After the spring steel incident, the materials laboratory specially made a lot of tests on the black iron snail. After the iron element was separated, the magicians were surprised to find that the density of this iron element was slightly lower than that of normal steel, which was obviously the isotope that the LORD had said.

    After testing nearly a hundred different proportions of formula, the lions found that the spring steel with 4% new iron isotope had the best comprehensive performance.

    The second new part of ATV is 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''s still hidden in a nobody''s corner of the planet, completely unknown.

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

    When Renault asked the rune magician what material was soft, elastic, and could be pressed on the ground to rub hard, all the rune magicians told him a word in one voice.

    Nima gum!

    The gelatinous substance extracted from Sargassum purpureum, i.e. Sargassum alginate, is mixed with a kind of mineral material called "NIMA powder". After a certain period of melting, the gray gelatinous substance is NIMA gum.

    When these Rune magicians were still keen on magic figures, they often used NIMA glue to fill the inner space of magic figures to fix the internal parts.

    Nima gum perfectly meets all the requirements of the Lord. It''s elastic and soft. Even if you rub the stone on the surface of NIMA gum, you won''t see many worn particles.

    In addition, its hardness can also be adjusted. The higher the proportion of NIMA powder is, the higher the hardness is, and the wear resistance will be enhanced, but the elasticity will be reduced, and vice versa.
