Different ranks of evolved officers represent an era. The material definitions of each era are different. For example, in the Bronze Age, there is no concept of steel as materials. In the Captain's Empire, there is no soybeans and peanuts as specialized in storage as strategic materials. The list of materials exchanges of Zhao Weiguo Ren Di has seen Ren Di, which is a rich variety that made Ren Di jealous, but Zhao Weiguo is a school official and Ren Di is a lieutenant. Although Ren Di is in the same camp as Zhao Weiguo, the upper limit of material exchange can only reach the captain level in the Haisong plane. However, the evolutionary officers in Ren Di's area are all earthlings, and there are no ancient species in the exchange of materials, such as saber-toothed tiger fur and mammoth meat. There are no alien species, and all materials are from the history of earth civilization.

This is the common attribute of the officers of the earth's evolution. If Ren Di's redemption authority is at the colonel level, Ren Di will plant a large number of industrial crops such as peanuts and soybeans in this world to develop biofuel technology. What is not short of in this world is territory, and this large number of territory is vacant between the lord's territories as space for robbers to cut paths and merchants to move. For the lords, fiefs that rule the prosperous areas are empty, as for other places, they are used as places to rush horses.

However, this world has oil-producing crops, and it is a plant similar to bacteria, without sunlight. When the big trees in the forest fall down, under sufficient water, this fungus will grow all over the tree trunk, absorb fiber nutrients, and quickly form a huge umbrella cover. There are a large number of seeds on the umbrella cover, the size of sesame seeds will be eaten by forest animals, chewed and obtained energy. Of course, some of the unchewed ones will be excreted with the feces. Sowing the whole forest.

The oil of this seed is very high. As long as there is enough wood supply to decompose for two weeks, it can grow from the seed state to a huge umbrella for sowing. So far, the Dawn Commune has just begun to use this crop to process the scraps after cutting down trees and the large amount of straw collected in the farmland. Since there is no need for sunlight to maintain water supply, it can quickly obtain high oil seeds. When Ren Di saw this crop, he felt a kind of depressing feeling that people in this world were so lucky. By asking whether this crop can be exchanged in the evolution space, the evolutionary narrative is a firm description that it is not a crop in his own region's history and cannot be used as a material.

But now this plane does not prevent Ren Di from using it like this. Ren Di has the technology to turn vegetable oil into fuel oil. A large number of unsaturated vegetable oils can be turned into alkane diesel through hydrocracking, providing a power source for the world's first batch of internal combustion engine machinery.

The single-wing propeller aircraft in the sky carried two machine guns and soared in the sky. The long self-propelled cannons on the ground. With the movement of the army, the army of the Dawn Commune is now approaching the era of mechanization. Of course, it is only approaching. There is no tank army. Yun Chenhe's wave has only 300 heavy self-propelled cannons and 276 aircraft. For the design of this aircraft, Ren Di has put a lot of brains on it, because the air pressure is three times that of the earth, and the wings can obtain greater ascent power and also bear greater resistance. If it is for speed, the propeller can be smaller and the wings can be smaller. The shape of the fighter is different from that of the earth. There is a propeller hanging in front, and the wings are designed for the swept wings of the Earth's supersonic era. It is made of aluminum alloy material to form the body.

As for the flight speed, the machine engine is diesel-burning. When all high-power engines output energy, they will inevitably emit heat, causing the entire engine to overheat. The mages in the sky who rely on wind-based magic are life after all. Only cold-blooded animals in carbon-based life can withstand a large change in body temperature. However, this body temperature changes greatly. Take crocodiles as an example. Crocodiles that do not bask in the sun, the slow movement of the crocodile is a plate of dishes. They can directly drag their tails into the fire and grill. For high-temperature animals, the chemical reaction accuracy in the body is very high. The synthesis of a certain protein and vitamin in the body is a beat slower or faster. You will definitely have problems with your body. For example, gastrointestinal colds, endocrine disorders, etc.

If there is a violent fluctuation, okay, the high fever is 39 degrees and twenty hours. It is twice higher than the body temperature. Who thinks that I can go to work the next day? The energy release of the mage is limited by the essence of carbon-based life. It must be a gentle process. A large fireball is dispatched by magic, and it needs to be connected many times when it is released outside the body. Moreover, there is a cd cast. If you invest too much, you will feel tired. This is a phenomenon of cell life in the body, and it needs to be reregulated under energy interference.

In short, carbon-based life should not compare power with steel machines, unless you practice to the point where you are not as good as the world, eat only lead and mercury elixirs, get rid of the limitations of carbon-based life, and evolve towards the direction of t1000 terminator. Of course, you will get rid of the body of carbon-based life and have no desire or desire for carbon-based life. You will become a true immortal saint who is pure.

However, this world seems that magicians cannot do this. It is very free to move to the wind. The great magician can achieve a flight speed of 80 meters, while the maximum flight speed of the intermediate magician can only reach 40 meters per second. Of course, the flight time of the great magician is by no means comparable to that of the intermediate magician. Of course, what about the aluminum alloy machine? This strange plane with swept wing and propeller head takes off and then rises directly after taking off a 50-meter runway. The flight speed reaches 120 meters per second when diving from the sky. The take-off weight of 1.6 tons carries a cross cannon with two wings hanging on it.

Of course, this aircraft is not as good as the magician's agility in free flight, but the key situation is that the person who flies such a fighter has no sense of magic? A high-level army like a pilot must of course allow new mages with firm revolutionary will and urgent revolutionary needs to operate.

The battle in the sky was not a fight or a dog fight from the beginning, but a knight-like charge war. Sky Knight Hailante touched the soft fur of his mount. As Sky Knight, Hailante was one of the few men. Sky Knights needed to strictly control their weight, not only without gorgeous armor, but also to control their diet as much as possible. The large raptor sitting down on Hailante can reach ten meters of wingspan. It is an absolute behemoth, the Empire had to take out this air force to deal with the threat in the sky.

However, it was useless. HaiLant felt the panic of his mount and wanted to quickly escape from this sky. A sound that had never appeared in the sky before cut through the sky. This sound was not the chirping of any bird. It was the friction between the metal body and the air, and the sound of the propeller running rapidly to cut the air.

Twenty fighter jets in the distance seemed to have also discovered large raptors in the sky. They randomly drew a huge circle with this raptor team and went directly to the direction of the sun. When they circled this circle, they were spiraling up.

There is no so-called scene where the Sky Knight shoots the fighter jet with a bow and arrow, because when the fighter discovers the Sky Knight, it does not enter the range of the bow and arrow at all, but relies on the brute force of the machine to rise rapidly and climb to the attack angle.

HaiLante immediately controlled the Raptor to sit down and descended rapidly. Why did it fall? Because the climbing speed of birds cannot be compared with the fighter planes at all, HaiLante has seen three fighter planes strangling against his Sky Knight.

As expected, the plane climbed to a certain height and began to dive towards the sun in the sky with a very disgusting back to the sun in the sky. The birds of prey could not directly look at this huge size and extremely high speed. This routine was very familiar with raptors because raptors also dive in this way when catching birds, with sunlight buffs, dive from high altitude. Large birds of prey never compare with small birds to the flexibility of the low altitude. They were directly in the sky. When they saw the shadow of their wingspan aimed at the target object below (at this time, the target object looked up and found that the raptor was in the sun.), and dived directly, and the eyes were so flexible that they could be blinded by the sun.

The battle technique of the Dawn Commune fighter jet at this time was the tactic of raptors to capture birds. When the above was aimed at such a terrifying thing, the overlords in the sky suddenly felt fear in their bloodlines, and it seemed that the giant dragon once culled to kill him like this.

Dozens of Sky Knights immediately dispersed in panic.

Abu, the new magician of Dawn Commune, as a new magician, found a slow magic energy interference point ahead twenty kilometers away, so he quickly pulled up the fighter and finally caught such a sky knight flying in line. According to the tactical textbook, he completed the ascent in the sky. In the process of the chemical energy continuously transforming into kinetic energy and then continuing to transform into gravitational potential energy, the momentum of the fighter was rising in the sky.

The forces must pay attention to the battle. When the aircraft's momentum reaches its peak, it is backed by the sun and dives from a high altitude, and a kilometer away, HaiLant feels a sense of a world of a doomsday. This feeling is like the feeling of an unarmed civilian facing a heavy cavalry, and it is even worse. A 1.6 tons object aimed at you from the sky at a speed of more than 100 meters per second. This is the dump truck stepped on the accelerator on the road, giving the people ahead the feeling.

How can birds and people not be afraid as life? The magic probes of Abu’s two wrists lit up instantly, which was the encouraging of magic power input. Because the raptors in this world have more or less wind-type magic talents, not to kill people, but to pull out a huge air wall at the moment of falling. On the one hand, it slows down itself, and on the other hand, it directly overwhelms the running animals to the ground. Of course, these raptors will unconsciously use their magical abilities to control their feathers when flying.

Feeling the probe pointing on the wrists of both hands, at 500 meters, twenty fighter jets pressed the button of the machine gun firing. Under the huge recoil of the two-wing machine gun, the plane suddenly slowed down, and the bullet turned into a barrage to cover the team of prey in the sky. Feathers and blood, human corpses and bird corpses fell into the sky. After the twenty fighter jets completed the strafing, they quickly stretched and left. Hailante, who was hanging on the branch, straightened his dislocated arm and looked at the long-lived Fixed Wing aircraft. A complex look appeared in his eyes. A profession seemed to be completely out of the battlefield.

It is not just the Air Knight who is behind the scenes. The entire battlefield situation has changed. Fifty kilometers southwest of the capital of the empire, huge magic in the forbidden airfield was maintained under the shining of the magic circle. The principle of the entire forbidden air magic needs to be explained easily. Although this airspace looks nothing, it is wrapped in a huge bubble. You can't see this bubble because it is very thin. Any subtle thing will have an amazing effect once it obtains a significant strength. For example, nano-flying silk that can cut the ship into playing cards.

What if such a layer of things thinner than plastic film is shrouded in the sky? Just like a soap bubble, when a large bird crashes into one head, the huge bubble is like being blown into it, and when it is concave, it will become a large bubble that firmly wraps the large birds. The large bubble will be completely isolated. The airflow of the birds flapping their wings and the circulation of the external airflow. The airflow of the birds wings will be completely bound by this invisible bubble. After the entire bird loses its stretching force, it will fall directly to the ground with the bubble. When it falls to a certain speed, the entire bubble will decompose, and the raptors that have fallen by powerful gravity will directly hit the ground. This is the forbidden air magic.
