Genetic engineering involves the combination of bases, a vast system of protein maintenance, which should be part of the design. That is, the simple arrangement and combination of parts composed of materials will reach a compromise between various indicators of performance and internal friction. The various compromises are the need for experimental validation of data. When the more things need to be combined, the more difficult it is to design.

In the early stage of industry, mechanical parts were stupid and clumsy, but in the industry, they became more and more refined, and there were more and more types of standard parts. It's getting harder and harder to design. Until human genetic engineering, human gene fragments corresponded to the order of protein type generation and the amount generated. Design is more difficult than all other industrial projects.

However, with the increase in the variety of industrial parts, genetic engineering is actually nanoengineering with infinite difficulty in design. Although the biochemical data in the loess area has accumulated very sufficiently, compared with the natural coordination of natural people who rely on genes, the current biochemical technology for the coordinated growth of the loess area is still stupid and stupid.

However, with the complexity of the industry, the machinery industry in the loess area is also slowly starting. The type of part determines the difficulty of the design, while the type of material determines the type of part.

And what is material technology? The material depends on the spawn environment. Just as the elements of human beings are similar to the elements of the sea. The greater the ability to create extreme environments, the stronger the material technology. Extreme high temperatures, extreme high pressures, extreme low temperatures, and can maintain stable low temperatures. There is an extreme vacuum, a vacuum in which even one atom has to be counted by number.

If the above extreme conditions are maintained, it will take time to maintain the conditions. Because any dynamic reaction in the world takes time. Generating material is a dynamic process, so extreme environments take time to maintain.

Therefore, the technical threshold and difficulty of controlled thermonuclear fusion are almost a boundary of civilization development. Extreme conditions of more than 100 million tonnes are maintained on Earth, and this thermonuclear reactor also emits a large amount of neutron radiation that cannot be confined by an electric field. So much so that most of the materials in the Tomac reactor also have to consider protection against neutron irradiation. Especially chips. This basically eliminates most of the civilian chips that are very fast, and must use space chips with very high standards.

The types of industries involved behind nuclear reactors, industrial projects. The environment generated by various new materials alone is enough to kill the current advancement of this world.

At present, the world's science and technology are basically electronic, highly electronic. Artificial intelligence AI warfare makes the world look like black technology is frequent. To find the direction of energy, the means are used to the extreme. If you look at it in a higher civilization, this is like an era when science and technology have come to a halt and all kinds of crooked ways have developed to the extreme.

If we look at a stagnant steam era, we may feel very cool, with several chimneys erected by oversized super-giant multi-tracks, and riveted bodies full of steam smoke, rumbling forward.

There were no aircraft carriers, no planes, not even biplane triplanes on the sea, but battleships, battleships with numerous turrets, on land, railroad derivatives on both sides, dozens of Gusta cannons bombarded each other, and in the sky, huge airships oppressively descended high in the air, and then dropped ammunition. No electricity, no internal combustion engines, no petrochemicals, no welding. Steam technology will go to the extreme.

However, before the steam technology on earth could develop in this way, it was eliminated, and the battleships with oil-burning engines replaced the warships with internal combustion engines, and the small airplanes with light weight and high power that burned fuel replaced the airships, ending the battleships on the sea.

In the awesome steam engine technology, the electric revolution represented by the nascent internal combustion engine electricity is about to be brought to an end.

And this era is the limit of continuous development based on the electronic age. Since there is no longer the ability to manufacture new materials, it can only rely on the industrial base of this era in terms of processing. In terms of design, new designs will be constantly introduced, while leapfrog designs cannot be implemented due to insufficient congenital conditions. And the weapons used in these advanced tactics are not advanced compared to the 21st century, but are pursuing mass production.

At least in no#The degree of requirements for the engine is a little lower than that of the manned machine. As for the reason, the bigger the thing is made, the more unstable the strength structure is. Small and medium-thrust turbofan engines have a high thrust-to-weight ratio and low material requirements, which means that some expensive metals are not needed. For example, rhenium, which is light and has high strength under high heat, can be replaced by tungsten, a metal with high weight and high temperature resistance, anyway, the thrust ratio of small and medium-sized turbofans is high, and the performance loss caused by this weight is allowed. So the current no-# man-machine is mass-produced. If it were a seventeen-ton manned fighter in the air. The current Zhou Tian Alliance cannot afford to fight this war, and all the countries on the planet cannot afford to fight such a war.

And now this war is raging, and tens of thousands of tons of planes are flying in the sky. Crossfire with lasers. Unmanned vehicles on the ground form troops and attack with the control of the soldiers.

When the Loess District tried to advance with the most orthodox path of scientific and technological progress, in the waters west of Alagascar, electromagnetic cannons rose on the surface of the sea, and under the imprint of the sky and back and forth # man-machine group, these magnetic cannons fired. It was as if a ball of light was shot out, and the sea area where the magnetic cannon was deployed sank under the huge reaction force, and the foaming waves spread out in all directions......

A minute later, the front line, hundreds of combat vehicles and thousands of soldiers fought on the battlefield. Well, there aren't many of them, but the arrangement isn't dense. If you want to know how many people there are in one or two thousand, think of the playground of an elementary school. As for the number of several hundred combat vehicles, one can imagine blocking the traffic flow of the road at two stops.

However, there was no order on the sandy battlefield, only a front. The electromagnetic cannon that fired the hard steel core shells constantly tore at the armor of both sides. From time to time, wrecked tanks on the battlefield emitted white gas. Well, this is the scene of a liquid nitrogen leak. Liquid nitrogen is required to cool down the electromagnetic system for start-up.

Of course, after the leakage is over, the magnetic cage of the superconducting material cannot be maintained, and the cold ion battery inside the chariot will begin to radiate heat due to the appearance of resistance, and the electrical energy will be converted into heat energy. Batteries made on the principle of ball lightning are not good at all. Instability is too dangerous, and this nature dooms batteries of this principle to be unsuitable for civilian use. Only in this age of madness will this high-energy technology be carried forward because of the battlefield.

The wrecked tank burned out from the inside, and red-hot metal liquid escaped from the bottom armor. The tracks of the combat vehicle were glued to the ground.

At this time, several bright stars appeared in the sky, and several combat vehicles, which were used as air defenses, hurriedly turned the laser tower in the direction in which these stars appeared. However, it was then attacked by hostile ground forces, high-explosive bombs. So laser weapons can only shift priorities.

In this way, the nuclear explosion was like a fried egg yolk, and the fireball expanded and pushed the shock wave to expand, overturning as many as thirty tanks within a range of 500 meters. The tank in the core of the most explosive core, pushed by the fireball, flipped over a dozen times in a row. Then it seems that the energy battery is broken, and the chariot disintegrates directly in the air, and the interior of the chariot is softened by the high temperature, and with the moment of disintegration, the red burning condition inside is revealed.

The Rand's attack was thwarted, and ten minutes later Jelise was informed of the defeat at the front. Well, there have been a lot of failures of this kind recently, and Zhou Tianhemeng's sharply improved command ability has improved sharply, which makes Jie Lisi feel a little headache. Looking at a grid of regular triangles on the map, several of the triangle signs appear in the area representing nuclear flashes. Jeris looked at the strategic map and could only shrink and redeploy the army in the southeast. Because the area occupied by Sun Chiyong, southwest of Alagascar, by the sea, already threatens his flank.

So the seven mechanized corps, already laid out in the south, were forced to return and consolidate the defensive line. After making these orders, Jeris brought herself a pot of tea, smiled and said, "It looks interesting." ”

At this time, a projection communication appeared behind Jie Lisi, and Jie Lisi tilted her head, and the information gem on her smooth forehead hidden in her bangs flickered. The full-body clothes are clinging to the figure and appear to be ceramic. The chair in which Jeris was sitting turned gracefully. Said to the light and shadow behind him: "Is there something in the rear?" ”

Kidd said: "The remts have come to contact us. Jeris showed a hint of surprise on her face, and then said, "It's rare to take the initiative to contact us." Kidd said: "This war is a full-scale war launched by the Zhoutian Alliance, and it is also the most powerful counterattack force of the Zhoutian Alliance. ”

"What they say, or what you think," said Jeris. It's still everyone's opinion. Kidd said: "What they mentioned, we think is correct, and it is not appropriate to have a contradiction now." ”

Jeris adjusted the map in the command room, as if space was shifting, and Jeris was in the north of North America as if she was traveling in space. "But there is always a contradiction between the spears. ”

Kidd looked at the broken archipelago of northern Canada, the tentacles of North America reaching into the Arctic Circle. Kidd pointed to the archipelago between Greenland and Alagascar, which is not a small area of land in North America and Canada, but the Arctic has become basically an inland lake for the Lantes.

Jeris looked at the map and smiled and said, "So generous, so are there any additional requirements?" ”

Kidd said: "Originally, we were asked to start a diversionary war in the Asian continent, but we refused. Now let's join them in a powerful northern offensive in four months' time. ”

"What do they want to do?" "Southern Africa, southern South America, these two regions are ready to attack," Kidd said. Jeris nodded and said, "We bite the fish head, they eat meat." Agreed?"

Kidd nodded and said, "Yes, but the news has reached the Loess District." ”
