Rong Xing, a planet without a moon and therefore no tides, was hit by a large number of comets with the comet region of the star where Rong Star is located 13,000 years ago, adding a large amount of hydrogen to the planet.

Mars Venus also had an ocean in the early days, but the magnetic field was not strong enough, and under the blowing of the solar wind for hundreds of millions of years, the hydrogen element was gradually lost and became a desert planet. Without the Moon, without geomagnetism, there would be no oceans and no life. That's true, but it's a process, a process that takes hundreds of millions of years, to say the least. Just as people die of cancer, but not immediately, human lifespan and history do not need to worry about the long process of natural aging of the planet.

Like most planets colonized by humans, Rongxing is an acquired planet that is artificially replenished with hydrogen. After all, it is rare for a planet like Earth to be blessed with a history of life that can naturally maintain billions of years of life. Planets that have no satellites, no geomagnetism, a certain gravitational pull, and can maintain a living environment for millions of years are enough for humans.

This is the planet where Luan's mission has landed. After looking at the mission introduction, Lu An was speechless. The mission is simply to survive on this planet for a year and travel as far as you can. The task is not worth complaining about, it is the world that is worth complaining about.

Lu An looked at the social environment of this classical era, and couldn't help but complain in the rehearsal: "This is the future world? I day. ”

The city in front of Lu An is an ancient city with oriental characteristics. The thick city walls, cornices and corners, huge columns, beams, purlins, and other wooden structures are constructed with blue bricks and yellow mud, which illustrate its cultural origin.

Unlike classical China, there was a slight difference in productivity, with cement on the roads and glass ornaments generally hung on wooden window mullions. And on the street, you can see steam boilers spitting hot gas.

The city built a small railway to transport charcoal for the fuel of the steam engine, and every day a small train sprayed this whistle to drag a large amount of charcoal into the city. The warehouses in the city have granaries and charcoal silos, hay tanks.

The overall level of science and technology should have been at the level of Tsarist Russia during the Crimean War. But technology can only go so far. Because there was no coal, Luan looked at the fuel used in the city, which was all charcoal, and there was no coal.

The absence of coal means that the temperature of the steelmaking furnace is too low, which limits the development of the technology tree of steel materials, and the technology tree of steel materials is limited, and at most it can only smelt carbon steel, and special steels such as silicon steel cannot produce high-voltage power technology trees cannot be started.

The Earth's human technology tree is built on the pedal of fossil fuels, and if fossil fuels are exhausted, human civilization will be extinguished if humans are unable to recruit alternative energy sources. Fortunately, in the 21st century, there is a light in the way of energy on the planet, nuclear energy can support energy, and combustible ice has renewable properties.

(The formation time is much faster than that of oil.) Stirring the seabed mud layer of combustible ice will not cause a large-scale leakage of combustible ice into methane, because methane is in its normal form at that water pressure and temperature. Even gaseous methane can turn into combustible ice again. Terrestrial biomass is deposited at the bottom of ponds and biomass becomes biogas, while organic matter that has been deposited on the ocean floor for thousands of years in the marine biosphere produces methane and becomes combustible ice)

The best sustainable development is not simply to save energy, but to find alternative energy sources before they run out, and to save them in the name of environmental protection, without thinking about alternative energy in the future, is actually pseudo-environmentalism. Lu An, who does not know the history of the development of this planet, suspects that the world he is in now is precisely the future of running out of coal, which is pedal energy, and not finding a new energy.

Now the city is burning charcoal, and there are tins like ceramic cans hidden under the roof tiles of homes, which use solar energy to heat the water. It's a very environmentally friendly approach, and it's also quite helpless. There is no coal oil fuel. Technology has stagnated.

The patrol soldiers on the city were dressed in black cotton wool. At first glance, it is the product of industrial looms. The main weapon was supposed to be a front-loading musket. During the rehearsal, Luan snatched the soldiers' satchels and saw them using paper-shelled bullets.

Luan didn't have any problem sneaking into the city, and the city gate opened a blind eye to Luan inside, and they only recorded the van with a notebook.

Upon entering the city, Luan took a quick look at the currency on the street. Lu An frowned, this world uses silver currency. I only have a box of gold leaves here that can be used as currency. But now if you take out the gold leaf like this, it is a child's arms, and it is easy to be remembered by people with a heart.

Encountering this tangled situation, Lu An misses Li Sanxiang a little, if Li Sanxiang is here, I'm afraid everything will be arranged.

However, Lu An was entangled for a while, and finally acted, he entered a science fiction world, and the background introduction of Yuan Yi is also that mankind has entered the era of space colonization, how to do it, but what he sees now is the era of classical Chinese steam style.

While Lu An was wandering the streets, using the rehearsal to taste the food on the street, Lu An saw his light curtain go off during the rehearsal. Mercenaries can talk to each other upon seeing them enter the mission. (However, this kind of call between teammates who are not on the same team costs merit points - although it is not much.)

In the first rehearsal, Lu An connected one of them and had a minute-long conversation.

In the second rehearsal, Lu An connected to the next one.

There were a total of twenty-seven communications, and Lu Andu contacted them one by one in different rehearsals. I was surprised to find that Si Xuan and Yan Yun were also here. This task worth tens of millions, Si Xuan and Yan Yun obviously can't afford this price by themselves. These two should be funded by large organizations.

After thinking about it for a while, Lu An decided to connect to Si Xuan's communication in reality.

If it was Si Xuan in the past, Lu An felt that he could still get along with him, if Si Xuan changed, from an honest man to a cunning person, it was just a task, and if he just learned to hide it, it would be difficult to hide all the horses' feet. And Lu An is confident that he can use the rehearsal to knock out the truth from Si Xuan.

The camera switched to Si Xuan, Si Xuan's team, there were a total of five people, the captain was a twenty-six-year-old man named Beijaw After communicating two or three times, he waved his hand to his teammates on the side and said: "He didn't accept our report, and the other two teams didn't receive the news of forming a team, it seems that this pangolin is preparing to be a lone ranger." Be careful. ”

Feng Daring Do (32-year-old man) said: "Pangolin, this is a very timid name. ”

It's just that it's private, and other people can't see it.

Si Xuan opened the light curtain, and a surprised sound came out of his mouth: "Huh". And Yan Yun on the side exclaimed in a low voice: "It's you?" ”

Lu An saw Si Xuan and Yan Yun here, and said in a helpless tone in reality: "Si Xuan, it's me, I'm a little confused about this task." ”

Si Xuan was stunned, and without saying a word, he sent his location to Lu An, and Lu An saw this direction and immediately sent his location to Si Xuan. Revealing one's position to each other is a matter of showing sincerity.

The distance between the two sides is four hundred kilometers. Lu An couldn't help but sigh, if there is a high-speed rail for four hundred kilometers, this distance is nothing, but now.

Lu An said to Si Xuan with an embarrassed expression: "Isn't this a high-tech mission world?" Yan Yun on the side couldn't help but smile and said, "You don't seem to have any information about this world before you came in, right?" ”

After a few minutes of talking, Si Xuan raised his head and said to his teammates in a relaxed tone: "It's an acquaintance, no problem, this guy doesn't have the information provided by the organization, and now he is confused in this world." I'll go pick him up. ”

Beijaw looked at Si Xuan with a solemn gaze, and Si Xuan responded with a relaxed expression: "I have a novice mission with me, and I am only fourteen years old. Don't be so nervous. ”

Beijaw said: "Being able to get the concession of Yuan Yi at the age of fourteen can also make you let your guard down. Well, pangolins don't seem to be simple. ”

Si Xuan was stunned for a moment, then smiled self-deprecatingly and said, "Perhaps, it's me who is too simple." ”

Then Si Xuan looked at the north jaw and said, "Maybe as you said, the pangolin has some complicated ideas of its own. But if you are eager to break everyone's shell and dig out everyone's truth, you will miss a lot. ”

Beijaw nodded and said, "Okay, then he, you take care of it." With that, Beijaw opened the communication and began to contact the other teams, informing them that the pangolins had been in contact with their own team.

Unlike the squad released by the traversal monster, the squad released by the traversal monster is quite discordant, and the two sides are mostly competitive mechanisms. Seize the best opportunities. They often have to fight for opportunity, because their mission is too dangerous, and the price of bloodline exchange is very expensive.

As long as they can enter the corresponding plane, even second-rate opportunities can also obtain corresponding strength improvements, and first-class opportunities often mean first-class crises, and when they get their hands on them, they will become the focus of the whole world. (The kind that snatched the dragon slayer knife and was cut by Quan Wulin)

Space-time mercenaries often don't snatch first-class opportunities. For example, in the martial arts world, you can practice ordinary mental methods, and you will never rob the peerless martial arts that are remembered. Anyway, my bloodline qualifications are good. No need to wave, practice more ordinary mental method to figure it out, based on the ordinary mental method, under the cheap body repair welfare, from simple to complex study can figure out their own first-class mental method, just like the circuit system just made out of the circuit system will be very messy, all kinds of wires are soldered with an electric soldering iron, but tidy up, the lines are squarely arranged, and the colors are classified, everyone feels very tall.

At the beginning of the founding of the People's Republic of China, the rockets of the Dongfeng Long March series began to be studied by the local methods that the West despised, but with continuous accumulation and research, the precision and strength of the parts supplied by various industrial departments have improved, and they have become a first-class rocket and missile system. If you have thoroughly studied the third-rate and studied it yourself, you may not be able to call it first-class.

There are many third-rate opportunities, and everyone can often cooperate to obtain them.

It is also because the space-time mercenaries do not seize the first-class opportunity, and the reincarnator is on the cusp of grabbing the first-class opportunity, so in the wild plane, almost every encounter is the space-time mercenary who takes the initiative to ambush the reincarnated.

In order not to have a misunderstanding with the other two squads, unnecessary conflicts will arise. Later, Beijaw started a call, informing the other two teams of the pangolin's situation, informing them of the basic situation, and asking them not to be nervous about the pangolin's instability. After all, everyone came to this plane to reap the benefits. As long as no one is doing anything, there is no need for everyone to be on high alert to each other. (The main task is to keep an eye on Yuan Yi and inspect whether there are any special circumstances in this plane.) ）
