Due to lack of astronomical knowledge, Zhen Fei went wrong in the direction of the starry sky. If it weren't for the fact that Gao Gen still knew the constellations of the Milky Way, it would have made a different joke.
According to the position of Cygnus and Aquila provided by Gao Gen, the mathematics-savvy Qiao Bushi drew an accurate route, and then calculated the time. Qiao Bushi said: "If it goes well, we should Enter the earth in a year."
"Can you be sure?" Zhen Fei asked in surprise. Unexpectedly, Qiao Bushi was so amazing.
"Almost. I measured the size of the Cygnus constellation provided by Gorgon and the position angle with other constellations. It should be about 500 million kilometers. Our warship has been flying close to the earth in almost a year." The distance of 500 million kilometers. In the starry sky, it takes about a day to fly at the speed of light, but their warships need to fly for about a year. In front of the infinite starry sky, the speed and ability of human beings are simply weak.
"Great, when I get home, I will take you to see the scenery of the Bund." Excited, Zhen Fei hugged Qiao Bushi's shoulders.
Qiao Bushi did not struggle and refused. Even if he hugged himself tightly, closed his eyes and smiled, it was a blessing to be hugged by him.
On this day, an observer on duty at Jixiang discovered an iron tower erected on the planet. After careful observation, it was confirmed that it was a radio wave signal converter, because they had erected this kind of thing before and were very familiar with the appearance of the iron tower.
Zhen Fei, who received the news, immediately ordered the escort warship to look at it closely. In the quiet time, Zhen Fei once sent Tao Li and Ming Fan to lead people to explore the path to the starry sky, but the traces of these people were lost in the misty starry sky.
Later, Zhen Fei also funded the descendants of the ancient dynasty to enter the starry sky again, but there is no news. If they can be found and found, it would be a surprise.
The iron tower that Jixiang saw was far away, and the battleship would take more than a day to fly, and it took a lot of time to check it out once. Moreover, there are air barriers on the planets. After entering the atmosphere, the warships face many dangers. The last encounter on the golden planet is an example. Up to now, every warship has a spacesuit made of hydrogen, and A large amount of spare hydrogen, which is usually placed in the coldest position, so that the hydrogen becomes solidified. Because the battleship accepts distant stars in different positions, the place where the hydrogen is placed needs to hide from the stars. It is also very troublesome to change several positions every day. .
Later, Zhen Fei figured out a way and found an asteroid full of ice and snow. It took five days to venture to obtain the essence of ten thousand years of profound ice from the thick ice layer. This kind of profound ice essence has been since ancient times. It's at an ultra-low temperature, very cold, and the temperature is around one thousand degrees Celsius. The samurai didn’t dare to use his arm to grab it. He could only use a rope made of Xuemian to wrap the black ice essence, and then put it in an intermediate magic weapon, enclose the hydrogen equipment with the black ice essence. When using hydrogen, Sacrifice out.
This method proved to be effective. Xuanbing Essence created a natural giant cold storage with a temperature of about six hundred degrees below zero. This temperature cannot be achieved manually.
The samurai carefully approached the planet where he found the iron tower. This planet is not too big, with a diameter of about 30,000 kilometers. Although it is more than twice the size of the earth, it is a relatively common planet in the starry sky, and there is nothing special about it.
A total of three warships went to explore. In addition to the pilot and co-pilot, there were two observers. They closely observed the road in front of the warship from the auspicious lens. There may be danger.
After the battleship entered the atmosphere, everyone became nervous, and an observer cried out in surprise: "Look, it's in the direction of ten o'clock, what's that?"
Zhen Fei and the others also observed auspiciously from a distance, and saw that there was a layer of gray on the asteroid, which seemed to be foggy. The fog also had strips of patterns. It was very beautiful, like a haze. Blooming flowers.
Zhen Fei looked back at the Nine Heavens Profound Golden Compass, and saw that there was a lot of "fierce" in the direction facing the asteroid. His heart jumped wildly a few times, and he shouted: "Leave there immediately, don't enter the planet yet."
After receiving the order, the three warships immediately turned around and increased their speed to leave the atmosphere they had just entered.
The beautiful flower was getting closer and closer, and the samurai on the three battleships heard a roaring sound, like the sound of a stormy sea in the sea, and like the sound of countless demons coming out of hell.
Everyone was stunned.
what is this
The three warships flew desperately. Observers were observing the flower at close range and suddenly said: "That is a hurricane. It is a very rare atmospheric storm. Oh my God, I have never seen such a storm before. Destroyed."
Because the gas is unstable, it is easy to form a large destructive airflow transfer in the planet's atmosphere due to the vortex, air pressure, and gravity, which is the cause of the formation of hurricanes. As for how to prevent hurricanes, Zhen Fei and others have yet to find a pattern.
Relatively speaking, although this hurricane is fierce, it cannot cover the entire planet. After the three escaped warships escaped from the atmosphere, their speed suddenly accelerated. Then continue to enter the planet from another angle.
A hurricane is like a storm in the sea. It is terrible in the center of the storm, but ten meters deep underwater is a calm harbor. After the three warships entered the planet’s atmosphere, they slowed down. Zhen Fei and others commanded the warships to avoid the hurricane. One day later, the three warships slowly came to the planet’s surface. The reason why the speed is so slow is because of the three ships. When the battleship descends, it revolves around the planet and descends. This process itself is also observing the planet's environment from different angles. If it drops directly, the speed will be much faster, but it may bring disasters.
The iron tower was erected on the highest point of a mountain, and it was only discovered by observers in time because it was slightly higher than the rest of the planet. This was also a coincidence. If the position of the iron tower was moved to the other side, the observer would not find it.
The message from the samurai was: "There are two characters Tao Li on the tower, as well as the names of Zhang Manfeng and Dong Dali. It was our people who erected this tower."
"Collect some samples of land from different areas and come back." Zhen Fei ordered.
"Yes." The samurai who entered the planet agreed.
Zhen Fei immediately said: "From today, I will use radio signals to contact Tao Li and others non-stop until I get in touch. This may be an inn on their way."
The samurai who entered the planet could not see the hurricane, but Zhen Fei and others at a higher level were tracking the hurricane in the starry sky. An hour later, the hurricane changed, adding green and yellow to it.
No one knows how these two colors are formed. The hurricane is so terrible that no one dares to approach it. The most reliable guess is: "These two colors may be some kind of gas released by the planet. Such gas is generally highly toxic."
As the areas of green and yellow gradually increased, hurricanes also slowly declined, and finally sank into the planet's atmosphere and was obscured by low-altitude clouds.
Two days later, the three warships on the expedition flew back, and they handed over the collected samples to Zhen Fei. After inspection, Zhen Fei found that the planet was not soil, or there was only a small amount of soil, most of the samples were solid hydrogen and oxygen.
Why is this so
It can be inferred: "This planet does not have water yet. That is because the stars are still too far away. When the universe was formed, hydrogen and oxygen existed. Since there is no heat, hydrogen and oxygen exist in solid form. If this is the case. With the appearance of stars, hydrogen and oxygen will become gases and exist in the air. Then hydrogen and oxygen react and combine to form water. This is the change of nature. With temperature, there is The concentration of water and air is constantly adjusted, and the existence of life has been nurtured in the evolution of thousands of years."
This is the state of the earth billions of years ago, just like a person grows up from an embryo to a baby, then enters childhood, adolescence, youth, and then enters the stage of middle age and old age.
The starry sky is changing, the earth is changing, everyone is changing. It is time that drives this change. Time is eternal.
Both hydrogen and oxygen are good things. If these two gases are separated from water, a processing process is required, and the quantity is very small. If solid hydrogen and oxygen can be obtained from this planet, it will be useful in the future. It is also a kind of material in short supply.
The question now is: "If you want to get hydrogen and oxygen, what kind of stuff should you use to hold it?"
Although hydrogen gas is good, too many of these things can also be an extremely terrifying weapon. If the concentration of hydrogen is too high, only a small amount of sparks will burn, and an explosion will occur at a considerable concentration. If you don't do it well, get a gunpowder keg and come back and you will throw a rock on your own foot.
Therefore, Zhen Fei ordered to stay for a while to study how to get hydrogen and oxygen.
This process needs to be tested.
First, send someone to fill the storage tank of a mid-level artifact with hydrogen, and then put it in the battleship. Since the temperature inside the battleship is suitable for the human body, let's see how the solid hydrogen reacts.
The large amount of hydrogen is completely different from the little hydrogen they need to make space suits.
After a day, I entered the battleship that was doing the experiment and found that the hydrogen in the middle-level artifact had leaked out. That intermediate magic weapon has been broken. The magical artifact is a kind of more magical thing, its hardness and flexibility far exceed that of metal materials, and it is now broken.
The problem became serious. Observed through the camera installed on the experimental battleship, it was because of thermal expansion and contraction that the magic weapon was expanded.
Thermal expansion and contraction are a natural force, which is ubiquitous in nature. For example, when the temperature is too cold, an iron pipe is filled with water. When it encounters cold temperature, the water condenses into ice. In the process of shrinking, the soft water will pull the iron pipe apart, which means it will destroy the iron pipe. The full effect of.
This is the current situation. At extremely low temperatures, hydrogen becomes a solid state. At room temperature, hydrogen absorbs heat and becomes a gas, rapidly expanding, breaking the artifact. ()
