No matter how nice it sounds, it can't hide that this city-state is actually a buffer between the two powerful city-states of Perata, who is good at the air force, and Mia, who is good at mechanization, plus colonies.

Giacomo, the second man of Miana, led a large army into Padonia and immediately showed his hegemonic style, directly taking over the southern city. The city-state in the style of pure metal machinery comes into view. Ren Di and other people from modern society saw this city built by pure steel machinery. I was amazed at this completely different style of painting. The material used in the construction of modern cities is reinforced concrete. However, the cities of this world are composed of pure heavy metal.

Ren Di arrived in Padonia for twelve days, and when he arrived at this land, Ren Di felt that there was only one word to describe it, chaos, large and small forces like bandits in the mountains, buying guns from the southern arsenal, and dividing them everywhere on this land, several mines were divided between Pyrata and Miana, but it seemed that there seemed to be a little situation in Pelata, and the mines they occupied had been lost.

However, after entering the city, the entire industrial city of Padonia was rapidly expanding as thousands of industrial mechanics arrived here from Miana in airships. The area of the palace was built to provide accommodation for these high-ranking workers, and for the low-level workers, the local civilians were happy to pledge allegiance under the banner of Miana, oppressed by the powerful military machine and the material security of industry.

As for this senior mechanic or something, Ren Di is very competent, and he can easily blend into the palace area. Well, of course this is cheating.

"Oh my God, the earth is weak, let the Trisolarans take over the planet." When the environmental data of this planet was understood by Ren Di, Ren Di couldn't help but sigh at the richness of this world, and the earth was too barren compared to this planet. Regarding the doubts about the pressure and gravity of the world, Ren Di finally understood why the direction of scientific and technological development in this world is so different from the earth under the exact instrument measurement.

The atmosphere of this world is twelve times that of the Earth, and the acceleration due to gravity is 7.2 meters per second squared. Such a high atmospheric pressure means that a helium-filled balloon is 12 times more buoyant than the Earth at the same proportion, while the gravity of this world is only 73 times that of the Earth. Good guy, that is to say, the big guy with a rising power of only thirteen tons on the earth, can carry an astonishing two hundred tons on this planet. It is no wonder that the big airship that Ren Di saw at the beginning had such a huge power to lift hundreds of tons of objects for air transportation.

Such a large air resistance is enough to explain the development direction of the world's aircraft and the difference on the earth, and the high-speed aircraft on the earth cannot exert the high speed on the earth at all under such a large air resistance. The range of the bullet will be very short due to air resistance. In the case of reduced agility and reduced range, the world's aircraft compromised on load data. Various streamlined hulls equipped with helium bags and driven by two fan blades have become the mainstream aircraft in the world.

As for helium. Helium is not a rare element in the universe, it is the second largest element in the universe after hydrogen. The lack of this element on the earth does not mean that other planets are lacking, the atmosphere of this world is 37 percent oxygen, 18 percent carbon dioxide, 44 percent nitrogen, and the remaining 1 percent is mainly helium. In such a high-pressure and high-oxygen environment, with a low gravity environment, it is no wonder that the earth's travelers can carry 20 kilograms of load-bearing armor facing upwards and insist on walking. It is no wonder that the world's railways can be underdeveloped, and trade can be completed by twin airbags alone.

With a load capacity of 700 tons, there is no need for a long airplane track, just a landing shelf. And with a cheap source of helium, there is no reason for the world to develop long-distance freight trains. It is no wonder why the area of Pyrata, where the cliffs and peaks rise like Zhangjiajie, developed into a large city-state. That terrain on the earth is a land of trapped dragons from the perspective of feng shui, and from a scientific point of view, it means that the traffic roads are impassable, and there is no way to get rich. There are many terrains like this in China on the earth, and all kinds of strange minerals that can get rich are stored in these big mountain ranges full of ravines, but the people there are poor. Unless you know how to fly.

Of course, what is even more amazing is the mineral of this world - copper ore. Arriving in Padonia and witnessing the construction of steel-framed areas, Ren Di realized how the world could play like this. The world's steelmaking is not coal at all, but hydrogen, a much more powerful reducing agent than carbon.

Copper ore, a mineral that grows naturally in this area of bright crystals and high water content, relies on sunlight. It is the most important resource in this world, and the three major forces of human beings in the entire continent, no matter how different the culture, how huge the difference in science and technology trees, and how huge the difference in values, are all using the resource of copper ore.

Ren Di didn't know what the specific chemical formula of this thing was, maybe it wasn't a pure substance at all, it was a mixture of crystals that stored hydrogen, including silicon, magnesium, nickel, and aluminum. The levels of these four elements vary from pit to mine. For example, in Pyrata, where magnesium and aluminum are the main body of the copper ore crystals, occupy the main body.

A little water, full sunlight, this thing grows and precipitates naturally, there is no need to worry about mining depletion, after a simple industrial treatment will release a large amount of hydrogen, the world's steelmaking furnace is completely different from the earth's, although the mechanical processing is still in the steam age, but their materials, with the help of a large amount of hydrogen, the quality of the steel is really good, as for the titanium ore, a headache on the earth, industrial refining is also easy and pleasant for them.

Ren Di finally understood why the ore powder in his fire # gun could propel the bullet. The catalyst probe releases hydrogen from the ore powder, which is then introduced into the air by a gas conduction loop, triggering a high-temperature gas injection. However, due to the ultra-high temperature of the burning of magnesium and aluminum in the ore powder, it is very easy to corrode the barrel, resulting in the fact that rifled guns in this world are not popular. The rifling will be burned off directly.

However, when Ren Di told Li Cuncheng about this discovery, Li Cuncheng asked rhetorically: "Didn't our original world game maker release a detailed expansion film to explain these introductions?" ”

This answer made Ren Di Yimeng, feeling as if he had overlooked something important, the legend of the rise of the country continued this branch, and the plane before Ren Di crossed belonged to an unfinished work of the BIG company. There's no expansion at all.

I think of the message that the Japanese man used to say, "2008 Olympics Osaka" at the beginning of the crossing. Ren Di felt that things were a little complicated. After re-checking the situation with Li Cuncheng, I found that the world from which the two came from is roughly the same, but a few details are different, just take Li Cuncheng, the North Korean #fresh topic that Koreans are most concerned about, as an example. Li Cuncheng's world is not three fat. It is another son of Kim Jong Il.

And take the game world that the two have arrived in now as an example, the legend of the rise of this country continues, and the world of Li Cuncheng is well-made, the three races are well balanced, the shooting is good, the picture quality, the game engine is selected, the magic technology industry is perfectly combined, and the distribution overwhelms Blizzard's StarCraft II, and Warcraft III.

Looking at Li Cuncheng's narration, Ren Di and he determined from one detail after another, and both sides understood that the other party did not lie to themselves. Then this happens, two face-to-face people experience two different worlds.

"Has your memory been tampered with?" Li Cuncheng asked as he looked at Ren Di with suspicion on his face. "Parallel universe" Ren Di spit out the word, and Li Cuncheng also nodded with difficulty. If at the beginning of the crossing, the two traversers were still doubting the authenticity of the current world, but now they can't doubt it. If you want to doubt it, the authenticity of the world that you grew up in will also be overturned.

After communicating with Li Cuncheng, Ren Di got more information, such as the world where Ren Di was located, and the details of how the spaceship that fell at the beginning of this world created the three major civilizations. The steampunk civilization of Van Xi is the descendants of the scientific researchers on the original battleship, who landed safely in the lifeboat when the battleship fell, but because there were no other resources on the lifeboat, they had to start from scratch.

And the middle of the battleship transports the micron-level industrial swarm part of the fall in the middle of the continent, this part of the workers skillfully memorized the simple instructions for operating industrial nanorobots, with the passage of time, the accent of civilization is changing, and these particle robot instructions are indeed unchanged, inheriting the magic spell, you can summon the puppet battle magician from the fire circle earth circle crystal circle to start building cities in the desert, mining minerals, digging water sources, cultivating oases, and the Erin people occupy the desert in the middle of the continent.

The easternmost part of the continent was the last part of the battleship to fall, and at the last moment of the fall, only a small number of soldiers escaped from the battleship. This group of soldiers began to collect the technology systems in the ruins, the backup nuclear reaction systems on several warships were obtained, and several artificial intelligence to assist the military command gradually became gods as the Ked people developed. Under the guidance of several gods, the Ked built a nuclear reactor city. Quiet has developed for thousands of years.

As for the picture of the battle between Van Si and Erin in Ren Di's world game, there is a more detailed introduction in the game of Li Cuncheng's plane, the leader of Van Xi who fought with Erin and finally forced to blow up the bridge, is Miana, the king of the previous generation of the city-state bordering Erin - Giuseppe Ziamber, who is the father of Puchuzo and Giacomo, and is famous for his generosity to the people in the Vanchy city-states. However, he did not understand his two sons' enthusiasm for new weapons, especially mechs, which led to the two brothers becoming increasingly estranged from their father.

With this information, Li Cuncheng said it, and Ren Di understood the protagonist's feelings for his brother Pu Chuzuo. This is purely a tech nerd's dependence on his brother.
