Seeing Julian's enthusiastic eyes, Sun Shijie suddenly wanted to tell him that it was unrealistic to build tanks here. First of all, that thing was not a bicycle, but a rather complicated thing. Just relying on the materials and technology at hand materials and technology, Sun Shijie accidentally glanced back and happened to see the top turret of the Sky Fortress, and his eyes lit up. That's right, he doesn't need to build anything as complicated as a modern tank. This world doesn't even know what an armored vehicle is. As long as you get a steam-powered vehicle, add some iron armor and a freely rotating gun, wouldn't it be a tank? "Okay, I will design a super weapon for you that will transcend the ages and let you dominate the continent!" Sun Shijie smiled strangely at Julian, and suddenly he had an interesting idea in his mind. If the sky is ours, then it would be nice to leave the earth to you. "Really!?" "Dominate the mainland!?" The two were stunned by Sun Shijie's statement. After a while, Rommel suddenly said: "What an arrogant idea." "It is indeed a bit arrogant, I Personally, I think the most powerful thing in the world is still magic. However, the so-called strongest is not synonymous with mere power." Sun Shijie thought of Dean Berg's barely powerful magicians. They were very powerful, but they were all powerful. They are all scholars, not kings. The strength of an individual can never be an opponent of state institutions. After all, the world is balanced. Quantity and quality, quality and quantity. "What do you want to do?" Julian looked at Sun Shijie who quickened his pace in confusion. "Laboratory. Follow me." Soon, the three of them arrived at a laboratory in Moko. Sun Shijie asked someone for paper and pen, and began to design his 'toy tank'. "Are you going to start making like this? Don't you want a bunch of experimental products?" Julian asked in surprise when he saw Sun Shijie starting to draw with a ruler, pen and paper. In his opinion, alchemy and engineering seemed to start from messy experiments. started. "Well, of course we draw the design drawing first. Of course the experiment comes after the design. Just be quiet." Sun Shijie rolled his eyes at him. Start making basic ideas. A tank is a product of a balance of firepower, mobility and armor. Of course, in Sun Shijie's world, it takes many years to design a tank. Many experts demonstrated the experiments and then gradually built the new tank. But what Sun Shijie wanted to build was just a gun carriage that looked like a tank. There's no need to go to all that trouble. To build a gun carriage, the first and most important thing is to solve the walking problem. Making crawler tracks was a joke, so Sun Shijie planned to use solid rubber wheels instead of crawler tracks. As for the power issue, there is no high-power diesel engine or other industrial base in this world, so Sun Shijie instinctively thought of a relatively mature steam engine. But when it comes to tanks and armored vehicles, the armor and body must be very heavy, and the power of the small steam engine is too small to push it at all. To solve the problem, the car body must be reduced in weight. Physical weight loss is not feasible according to Sun Shijie's traditional thinking. The only way is to use magic and other things in this world. Taking into account the cost of reducing the weight of the magic array and the difficulty of mass production, Sun Shijie thought of using pumice to reduce weight. He had the same design on his suspended sports car. As long as a small amount of pumice is laid on the chassis to make the car body semi-suspended and reduce the load on the wheels, a small-power magic steam engine can also be driven. Regarding the operating system, Sun Shijie knew some of the transmission structures of tractors and had used them in previously manufactured steam engines, so he easily designed a simple operating system. Because there are no tracks, wheel steering is used when turning. Such a steering wheel, a forward gear, a reverse gear, a neutral gear, and a mechanical brake can be done. Regarding the car body, Sun Shijie finally decided to use the appearance of a wheeled tank destroyer. The car body is divided into two parts. The magic steam engine is installed in the front. The front four wheels are responsible for steering and driving, and the rear four wheels are responsible for load-bearing. Bow plates are also installed on the car to force vibrations and reduce vibrations. Regarding firepower, since the 30mm artillery installed on the equipment is expected to use black powder reflection and the recoil will be very small, it does not matter what the turret design is. As a spoof, Sun Shijie designed the turret based on the latest wedge-shaped tank turret. It was installed slightly behind the vehicle body and rotated with a hand-cranked gear. In this way, this ultra-small-caliber artillery has a shooting angle of 40 degrees upward and 20 degrees downward. As for aiming, it¡¯s easy to say, a coaxial white light direct sight scope and a coaxial magic night vision scope. Because it was too troublesome to fire the artillery at close range, Sun Shijie learned from the MB gun and installed a second turret on the first turret. An extra-thick glass observation window was installed on the second turret, and then a shooting hole was left. Specifically for magicians to carry out attacks. For example, the magician can release lightning magic, which is a taser, release fire, which is a flamethrower, and so on, with many functions. A magic circle of the Rings of Saturn can also be carved on the turret, which can greatly increase the tank's defense. With these benefits, the second turret can be said to be very powerful in close combat. What? You said the armor would isolate magical elements? It's easy to do. You can drill some holes as big as your little finger on the second turret, and also make holes in some important places on the body without pipes.Isn't this isolation? What? You said black powder fired produces smoke? It is easy to say that a storm magic circle is carved on the bottom of the barrel. After firing, a storm will be generated from the bottom immediately, just in time for the paper shell and smoke to be blown out of the muzzle. What? Type of shell? To put it bluntly, there is a solid bullet, an explosive bullet, and a shotgun. What? Is the artillery too powerful? Please, what era is this? Can large-caliber artillery be used? This is a destroyer. What? You said that if you encounter the five-pointed and six-pointed high-level magicians, they will be finished? Please, how many such high-level magicians are there? Besides, these crew members are all magicians! Armor? Oh, you said armor, well Sun Shijie, this idiot, only considered the use of armor at the end. Because of the power issues of the car, it is impossible to use steel for the entire car. Since the main enemies on the battlefield were bows, arrows, swords and low-powered old-fashioned artillery, Sun Shijie finally used the solid wood used to build the decks of flying battleships as armor materials. Solid wood is also called iron wood. The wood is more than half as light as steel. It has a hard texture, a certain degree of toughness and is not easy to burn. It is a very good wood. Even the keel and shell of the Sky Fortress are made of this kind of wood, and then wrapped with a layer of iron. In the end, Sun Shijie finalized the plan to use composite armor, which was made of magic alloy plates, rubber, and solid wood. Four layers of rubber. Then connect with through rivets. The specific distribution is as follows: the front of the tank turret is made of fifteen centimeters of solid wood, the outside is wrapped with rivets and a three millimeter thick magic alloy plate is mixed with a layer of rubber, and the sides of the turret. The second turret on top and the rear are made of ten centimeters of solid wood, one centimeter of rubber and three millimeters of magic alloy plates. Turrets are alchemically connected. Durable. In order to prevent the tank from breaking into pieces when it is hit, a layer of rubber is used to stick the inner wall inside. As for fire protection and so on. The natural magician among the crew members can cast water magic. In this way, the first wheeled tank in another world is shown on the drawings. The tank is two meters high at the top, 2.5 meters wide, and has eight solid rubber tires with a diameter of 80 centimeters. It is equipped with bow plate shock absorbers and pumice stones to reduce weight. The entire vehicle weighs less than three tons. Due to the extensive use of wood and pumice, the car is much lighter than imagined. Of course, this kind of thing cannot be completely advanced with pumice stones and jets, otherwise it will not be possible to achieve shooting stability. The diameter of the turret is one meter and a half, and it is quite wide inside. It looks very disproportionate to the 3) mm gun. The tank is planned to have three members, a loader and igniter, a shooter, and a driver. The number of ammunition carried is unknown. This is up to the shooter's preference. In order to ensure the safety of the crew, the greatest designer Sun Shijie designed the entrances and exits of this type of tank. In addition to the front driver's exit and the top exit, there is also an exit at the rear of the vehicle for emergency escape. As for the protective power, when the crew does not apply protective magic, the magic alloy plates and armor can resist the most lethal fire-attribute advanced magic once or twice in a short period of time, while the damage of other attribute magic gradually weakens. As for physics, apart from being hit by the legendary very advanced magical siege crossbow, or being hit head-on by a giant trebuchet, it can't cause much damage, and bows and arrows and swords are even more of a joke. Of course, well-trained members can use this tank to fight more flexibly, and against ordinary infantry, cavalry and intermediate magicians, the results can be imagined. Sun Shijie looked at the nondescript thing he had made and just wanted to hold his belly and laugh. Such a thing might be on the stage in this world. But on Earth, it would be embarrassing to take out such a thing. Its protective ability can only block one pistol and ordinary rifle bullets at best. It is estimated that even a light machine gun can easily beat it into a sieve! However, this thing was the spark of his own thoughts. Sun Shijie thought it was pretty good. In order to commemorate the tank Mark I (MKI), the originator of tanks on the earth, Sun Shijie specially named this tank Moko I. The abbreviation is also MKI. He carefully confirmed with him. After reviewing it, he gave the drawings to Julian and Rommel who were sitting aside. "Look, you can think of it as a new type of semi-magical, semi-mechanical war puppet. Of course it uses wheels instead of legs, and it needs someone to operate it. When the prototype comes out, you can take a look and produce it if you are satisfied. No If you're satisfied, I'll take it to the exhibition." Sun Shijie said irresponsibly: "According to what you said, it can resist guns, swords and general magic, and it can also fire cannonballs to attack enemies, but it has to resist advanced magic and giants. The siege crossbow depends on your ability. If you use it well, it's very powerful. If you use it poorly, it's just average." "Okay, let's get a prototype first and take a look." Captain, Julian was overjoyed when he looked at this drawing. He believed that Sun Shijie could create good things, so he was full of expectations for this war puppet. "Can this thing fly?" Rommel asked Sun Shijie. "Brother, are you out of your mind?" Sun Shijie looked at him in surprise: "Which of your eyes saw it growing wings?" "But we are aerial knights!" "I can't get you an aerial tank." Sun Shijie He said that he was helpless. Although he had long had the idea of ??developing an aircraft, he currently did not have enough time And even if he develops an airplane, its combat effectiveness may not be comparable to the agile Yalong. "Come on, brother, the Sky Fortress is yours, this is mine!" Julian pressed the drawing and smiled proudly.
