Chapter 590

Due to the lack of astronomical knowledge, Zhen Fei walked in the wrong direction in the starry sky. If Gao Gen didn't know the constellations of the galaxy, he would make a big joke.

According to the location of Cygnus and Aquila from the Earth provided by Gao gen, Qiao Bushi, who is proficient in mathematics, drew an accurate route and then calculated the time. Qiao Bushi said: "if it goes well, we should enter the earth in a year."

"Are you sure?" Zhen Fei asks in surprise. I didn't expect that Qiao Bushi was so marvelous.

"Almost. I measured the size of Cygnus constellation provided by gogen and its position angle with other constellations. It should be about 500 million kilometers. Our warship will be close to the earth in a year's flight." The distance of 500 million kilometers is about one day in the starry sky, that is, the speed of light. However, their warships need to fly for about one year. In front of the infinite starry sky, the speed and ability of human beings are simply weak.

"Great. When you get home, I'll take you to the Bund." Excited Zhen Fei hugs Qiao Bushi's shoulder.

Qiao Bushi did not struggle and refused. No matter he hugged himself tightly and closed his eyes with a smile, it was really happy to be hugged by him.

On this day, an observer on duty in auspicious found a tower erected on the planet. After careful observation, he confirmed that it was a radio signal converter, because they had also erected this kind of thing before, and they were very familiar with the appearance of the tower.

After receiving the news, Zhen Fei immediately ordered the escort warship to go for a close look. In the secluded world, Zhen Fei once sent Tao Li and Ming fan to lead people to explore the way of the starry sky, but they lost their trace in the starry sky.

Later, Zhen Fei also funded the descendants of the ancient dynasty to enter the starry sky again, but there was no news. If they could be found, it would be a surprise.

The tower that Ji Xiang saw was far away. The warship had to fly for more than a day. It took a lot of time to check it. Moreover, there are air barriers on the planet. After entering the atmosphere, warships face many dangers. The last encounter on the golden planet is an example. So far, every warship has a space suit made of hydrogen, and a large number of spare hydrogen. These hydrogen are usually placed in the coldest position, making hydrogen become a frozen state, Due to the different positions of the warship receiving the distant stars, the place where the hydrogen is placed needs to hide the stars, and it is also very troublesome to change several positions every day.

Later, Zhen Fei came up with a way to find an asteroid full of ice and snow. It took five days to venture to obtain the essence of ten thousand years of dark ice from the thick ice. This essence of dark ice has been in ultra-low temperature since ancient times, very cold, and the temperature is about 1000 degrees below zero. The samurai did not dare to use his arm to grasp it. He could only use the rope made of snow cotton to wrap the essence of the dark ice, and then put it in a medium level magic weapon to surround the hydrogen equipment with the essence of the dark ice. When using hydrogen, he would sacrifice it from the magic weapon.

This method has been proved to work. The essence of dark ice creates a natural giant cold storage with a temperature of about minus six hundred. This temperature can't be achieved artificially.

Samurai very carefully close to the discovery of the tower of the planet, this planet is not too big, the diameter of about 30000 kilometers, although more than twice the size of the earth, but in the sky belongs to the more common planet, nothing special.

There are three warships to explore. In addition to the pilot and co pilot, there are two observers. They closely observe the road in front of the warship from the auspicious camera. After all, they are out of the channel, which means that every meter in front of them may encounter danger.

After the warship entered the atmosphere, everyone was nervous. An observer exclaimed in surprise, "you see, it's at ten o'clock. What's that?"

Zhen Fei and others also observed from afar through auspicious observation. They saw that there was a layer of gray things on the asteroid, which seemed to be a mist. The mist also had a pattern, which was very beautiful, like a blooming flower.

Zhen Fei looked back at the nine day Xuan gold compass, only to see the direction of the asteroid suddenly many more "fierce" words. His heart immediately jumped wildly a few times, yelled: "you immediately leave there, do not enter the planet."

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 warriors on the three warships heard a roaring sound, like the sound of the rough sea, like the sound of countless demons coming out of hell.

Everyone was shocked.

what is it?

The three warships were flying desperately. The observer was watching the flower from a close range and suddenly said, "it's a hurricane. It's a very rare atmospheric storm. My God, I've never seen such a storm before. It's like destroying everything."

Because the gas is unstable, in the atmosphere of the planet due to eddy current, pressure, gravity, it is easy to form a destructive airflow transfer, that is the reason for the formation of hurricanes. As for how to prevent hurricanes, Zhen Fei and others have not yet found the law.

Relatively speaking, this hurricane, though fierce, cannot cover the whole planet. The speed of the three extricated warships speeded up after they got out of the atmosphere. And then move on to the planet from another angle.

A hurricane is like a storm in the sea. It's terrible in the center of the storm, but it's a calm harbor ten meters deep. After entering the planet's atmosphere, the three warships slowed down their descent. Zhen Fei and others directed the warships to avoid the hurricane. One day later, the three warships slowly came to the planet's surface layer. The reason why the speed was so slow was that the three warships were spinning around the planet when they descended. This process itself was observing the planet's environment from different angles. If it goes down directly, the speed will be much faster, but it may bring disaster.

The iron tower was erected at the highest place of a mountain. Because it was slightly higher than other parts of the planet, it would be found by the observers in time. This is also a coincidence. If the position of the iron tower was shifted to another side, the observers would not find it.

The samurai came back with the message: "there are two words on the tower: Tao Li, and the names of Zhang manfeng and Dong Dali. Our people set up the tower."

"Collect some land samples from different areas." Zhen Fei ordered.

"Yes." The warrior on the planet agreed.

Zhen Fei immediately said: "from today on, we keep using radio signals to contact Tao Li and others until we get in touch. This may be a post station for them."

The warrior entering the planet can't see the hurricane, but Zhen Fei and others at a higher level are tracking the hurricane in the starry sky. An hour later, the hurricane changes, adding green and yellow inside.

We don't know how these two colors came into being. The hurricane is so terrible that no one dares to get close to it. The most reliable guess is: "these two colors may be some kind of gas released by planets, which are generally highly toxic."

As the area of green and yellow gradually increases, the hurricane is also slowly descending, finally sinking into the deep atmosphere of the planet, covered by low-level clouds and disappearing.

Two days later, the exploration of the three warships flew back, they collected samples to Zhen Fei. After inspection, Zhenfei found that the planet is not covered with soil, or only a small amount of soil. Most of the samples are solid hydrogen and oxygen.

Why is that?

It can be inferred: "this planet has no water, because the star is still too far away from here. When the universe was formed, hydrogen and oxygen existed. Because there was no heat, hydrogen and oxygen existed in solid form. If there is a star, hydrogen and oxygen will become gas and exist in the air. Then hydrogen and oxygen will react and combine to form water. This is the change of nature. With temperature and water, the concentration of air is constantly adjusted. In the evolution of thousands of years, life has been bred. "

This is the state of the Earth billions of years ago, just like a person growing up from an embryo to a baby, then entering childhood, adolescence, youth, and then entering middle age and old age.

The sky is changing, so is the earth. Everyone is changing. It's time that makes this change. Time is eternal.

Hydrogen and oxygen are both good things. If these two gases are separated from water, a processing process is needed, and the quantity is very small. If solid hydrogen and oxygen can be obtained from this planet, they will be useful in the future, which is also one of the materials in short supply.

Now the question is, "what do you want to use for hydrogen and oxygen?"

Hydrogen is good, but if it's too much, it's a terrible weapon. If the concentration of hydrogen is too high, only a small amount of Mars will burn, and explosion will occur in a certain concentration. If you don't do it well and get a powder keg back, you'll lift a stone and hit yourself in the foot.

So 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 medium level magic weapon with hydrogen, and then put it in the warship. Because the temperature in the warship is suitable for human body, let's see how the solid hydrogen reacts.

A lot of hydrogen is totally different from the little bit of hydrogen they need to make space suits.

After a day, I entered the warship to do the experiment and found that the hydrogen in the medium level magic weapon leaked out. That medium level magic weapon is broken. The magic weapon is a kind of magic thing. Its hardness and flexibility far exceed those of metal materials. Now it is broken.

The problem became more and more serious. Through the observation of the camera placed on the experimental warship, it was because of the expansion of heat and contraction of cold that the weapon was expanded.

Heat expansion and cold contraction is a natural force, which is ubiquitous in nature. For example, when the temperature is too cold, put water in an iron pipe. When the temperature is too cold, the water condenses into ice. In the process of shrinkage, the soft water will pull the iron water pipe apart, which will destroy the complete effect of the iron pipe.

The current situation is like this. At extremely low temperature, hydrogen becomes solid. At normal temperature, hydrogen absorbs heat and becomes a gas state. It expands rapidly and breaks the magic weapon.
