Since the Industrial Revolution, humans have used metal parts to build complex machinery, and the complexity of machinery depends on the strength of the material and the energy density of the fuel. In theory, the use of energetic substances with extremely high energy density, such as enriched uranium, can support the existence of aerospace motherships. However, no material's strength can support the safe derivation of intense nuclear energy, so high power of small-mass nuclear energy engines can never be made.

Of course, there is no material of any strength to support the huge aerospace warship flying. Even if such metal structure is constructed on the ground, it will make a crunching sound of metal parts rubbing during a simulated earthquake of 7 or 8 level.

Although metal parts are extremely strong, they are still not absolutely rigid. Hundreds of meters long and millions of metal parts, and the slight deformations are superimposed on them, which is enough to cause a huge gap caused by twisting in the combination of tightly-sewn parts.

On the roof, Lu An looked at this paper creature he built himself, using a total of twenty kilograms of paper. The body was three meters long, one-five meters wide and thirty centimeters thick. Even if it was not attached to super power, the paper structure could support its internal stability. Of course, it would probably collapse after sprinkling water. In order to prevent this situation, Lu An's waterproof paper covered with plastic film.

During the rehearsal, Lu An complained about this floating battleship that took six hours of his real time and was spliced ​​with 270,000 paper parts.

"Flying Coffin? Or "White Banner"? Well, it's called Kite." Lu An naturally gave his spliced ​​floating battleship a name that fits the reality.

A certain emotional state named it the Flying Coffin because the body size of this thing is the same as the coffin. Another preview called the White Banner is because this thing stands for a white flag in the sky. The final decision was that it was called a kite because the body of the warship still had to connect to a bamboo frame wing. The entire wing was spread to fifteen meters. It was by flying a kite, and it was put into a high altitude with a rope twisted by a glass line, and then stood for it.

The entire kite is usually on standby in high altitude. There is no need to worry, because the turbofan parts covered by the internal conduction film will rotate rapidly with the wind at high altitude to drive the rotation axis. The entire kite collects kinetic energy at all times. The external wind flag on the kite and the internal gyroscope automatically adjust the posture. They float directly in the sky. This is the only way to float in the sky for a long time without the help of hydrogen buoyancy.

Usually Lu An is planning to let this thing float like this in the sky. When necessary, he will use it to leave the flying wings and float in the sky. This system called Kite carries about one kilogram of ammunition. The ammunition is a candle (melted after melting) match head and a thumb-sized date-shaped ammunition made of matches rubbed paper. It can accelerate to 400 meters, and paraffin is still relatively hard at low temperatures. Therefore, the kinetic energy lethality is considerable. The fire point caused after the impact can cause additional damage to the target. If there is a large amount of combustible material accumulation near the target, the destructive power of this type of projectile is still very high. There are a total of 300 projectiles, and the impact power is very considerable.

After the entire kite breaks away from the wing, Luan needs to maintain a stable flight attitude and float steadily over the air. If it is not controlled, it can be stuck in the air for four hours.

If the control is not carried out, the aerodynamic energy cannot be effectively collected in high altitudes, and the independent adjustment of the battleship's posture can be maintained on the spot by relying on the battleship's wind vane for four hours. However, this mechanical system is determined by the weather vane and has lag and will continue to circle in the sky until the kinetic energy of the internal supercurrent ring is exhausted.

Although it took only six hours to manufacture, the huge number of parts and combination techniques inside took six months to conduct continuous experiments, and the experiment process was performed in a six-minute preview. From outsiders, Lu An kept flying this strange big kite. Because during the actual flight, Lu An did not start the kite number and escaped from the flying wings.

After looking at the kite flying in the sky, Lu An paused: "This thing is good, but it's still too big. When you return to the main world, you can only put three things in the bed cabinet at most." This thing is actually very small. According to military standards, it is absolutely unaware of things. If the regular military wants to know that Lu An can make this thing, it will definitely be closely monitored, because this thing carries ten kilograms of explosives to play with Shenfeng, and its destructive power is similar to that of the cruise # missile.

Generally speaking, this thing is made of paper shells. According to the government's military cost, the cost is almost zero. Lu'an's total consumption is only forty yuan, which is just for buying paper. Of course, forty yuan is also considered a lunch box for Luan. It's quite distressing to build arms like this.

Lu An calculated the consumption situation of his main world in the next year and found that he would spend 60,000 yuan a year on food and tuition fees a year. In order not to make his interest outside of this kind of life, Lu An then spent too much on military spending according to the national average military spending standard of 3% of GDP. So Lu An also set a standard standard for himself in the main world, and the consumption of this thing should not exceed 1,800 yuan a year.

In fact, in the main world, even if Luan has a few million in cash, Ji Liu will call him as promised. But once Luan asks for so much money, Ji Liu will definitely investigate where he has used the money. As for the military expenditure issue, Luan feels that he can get some scrap newspapers from the school that no one wants to solve the problem of his manufacturing materials. By the way, as long as it is paper, it is enough. (Luan now regards paper as the country focuses on steel production)

With enough paper, Luan can even make automatic origami and automatic machine mechanical structures that cut paper. It can mass-produce and control the flight equipment over the entire Pudong city in one day. Luan has accumulated enough manufacturing knowledge through plagiarism and his own modification methods. If it is fully developed in the main world, it will be a desperate productivity in anyone's eyes.

Of course, even with such ability, Luan's deep-rooted nature is still trying his best to hide this ability. In Luan's experience, this experience is the "experience" developed by watching anime before the three battles. Many powerful villains in the anime are too confident in their powerful abilities, and end up being killed by someone's plot.

There is no super power that is useless, nor is there an invincible super power. Once the super power is inexplicably restrained by his opponent, the one who is waiting for him may end up with the rat crossing the street.

Luan's creed - there are no more abilities and means. If you use them randomly before encountering danger, you will exhaust all the means. The floating warship flew into the sky in the form of a kite. Luan looked at the Kite that was hovering steadily on his wings.

Lu An walked into the room, and there were a large number of models in the room. Of course, to outsiders, these models without the superpower of unresisting membranes were just paper structure models. Lu An walked straight to a cabinet and hugged three cartridges with a thick thigh.

After a little docking, wrap it with transparent tape. A two-meter-high rocket was formed. There was a mobile phone inside the tip of the rocket. Turn on the phone and put it in the positioning state.

With a burst of sparks, the huge fireworks took off. The monkey who was about to fly into the sky was covered with an unblocked film by Lu An, so it rose very quickly and quickly flew towards the distance.

Lu An turned on his phone and checked the positioning system on his phone. He only saw that the positioning system showed that the target was moving at high speed. Of course, this display was very unreliable. When the aircraft flew away from the location covered by the signal base station, the positioning information could not be obtained. Therefore, this rocket was in a zigzag shape in high altitude, from one city road and another city, using the signal base stations in the city to locate. Lu An, who was staying at the launch site, tried to adjust the direction of the rocket to a suitable angle.

Four hours later, in Jinrui and Li Sanxiang looked at the fireball that disintegrated in the air above the golf course (the unblocked film was removed and the speed decreased sharply. So in the end, a more obvious sound-light effect was generated). After the fireball dissipated, four parachutes were opened at a height of three thousand meters, and the speed destroyed the landings of the three umbrellas. Li Sanxiang couldn't help but cursed: "Damn it, it's convenient for you to pass on the message like this."

After saying that, Li Sanxiang immediately drove the vehicle towards the falling target four kilometers away. The positioning of the mobile phone showed that the express delivery was here.

This is how Luan delivers express delivery. The positioning system of the mobile phone allows Luan to know the rough motion route of the rocket. Then he controls the chance of the unimpeded membrane change so that the rocket moving in the air in a zero-resistance state can complete orbital adjustment. When transporting this express delivery, in order to ensure sufficient capacity, Luan specially used three rockets to complete the transmission. Of course, the most difficult thing is the atmospheric return step. After the positioning target of the mobile phone shows that it has reached the destination, Luan activates the reverse push mechanism to try to reduce the movement speed of the moving target.

If this system does not have any superpower participation, it will return to slow down time and space to verify the air flow when it continues to fall. It requires a large amount of equipment to simulate it. The materials of the rocket launch shell cannot be so careless, it must be made of special materials. Some even need to use ultrasonic wind tunnels. If any airflow is not calculated, the resistance generated can cause the aircraft to rotate hundreds of times. It is not even time to crash and it is directly destroyed by the centrifugal movement generated by the rotation.

The operations involved are operations of several digits after the decimal point, and the unimpeded superpower can make these operations omitted. Because the impact of the turbulent airflow is not necessary to consider, the projectile will successfully decelerate during the rotation process in the last continuous reverse jet. Throughout the process, the falling warhead is only affected by the force of the bottom reverse push. Therefore, there is no complicated operation.

Lu An destroyed forty smart phones throughout the rocket launch experiment. Finally, in the last thirteen experiments, he found that the process of falling down was discovered, and he called his mobile phone to prompt the busy tone to wait for the answer. (If you can connect, it means that the phone has not been destroyed yet). Lu An announced that he had mastered the technology of delivering express delivery.

Of course, this was just Lu An's own claim to control. In fact, Lu An had never seen the situation of the falling site on the spot. How much does the landing site deviate? Will the police and the army come to block the scene during the falling process? Lu An didn't know.

But forty minutes later, Li Sanxiang pried open the box and picked up the mobile phone and hard drive sent by Lu An. The first thing he did was to open Yuanyi Communication and said to Lu An, "Don't do this kind of transportation method in the future. You have been alarmed by half of my city here."
