No matter how far the technology of human civilization has developed, even if the current human civilization has the ability to reluctantly carry out interstellar voyages, the entire universe, no, even just a solar system, is vast and mysterious to human civilization.

Human civilization's understanding of the solar system is still only the tip of the iceberg.

From the inside to the outside, the solar system is composed of four terrestrial planets, then the asteroid belt, then four huge Jupiter-like planets, and then the Kuiper belt, which is the source of short-period comets, Pluto, Haumea and Ornia all belong here. Further beyond is the ecliptic discrete disk, where there is a celestial body larger than Pluto, Sedna. The aphelion of the objects here may even be as high as 1,000 astronomical units, or more than 150 billion kilometers.

This distance is very far, but it is important to note that the farthest distance of the ecliptic discrete disk is 150 billion kilometers from the Sun, and the estimated distance between the Oort cloud and the Sun is between 7.5 trillion and 18 trillion kilometers, so ...... Between the ecliptic discrete disk and the Oort cloud, there is a huge void with a range of trillions to tens of trillions of kilometers...... What is there in this great hollow?

Before Weifeng, the farthest distance traveled by human civilization was 50 billion kilometers. This is still in the category of the ecliptic discrete disk, and it has not yet come to this huge cavity, so naturally it has not been able to carry out field exploration of this area. Scientists have searched the area for years using various large telescopes, but have not found anything in the area.

Is this really a hollow? This seems a bit unacceptable from a common sense point of view.

In fact, Wei Feng's scientific research mission included the exploration of the cavitary area. Scientists hope to find something here to improve their understanding of how the solar system was formed and evolved. This work has always been carried out by Ye Luo, and there is no need for Wei Feng's interference. The Star Ocean spacecraft is equipped with a number of scientific instruments. Since the Star Ocean spacecraft left the range of the ecliptic discrete disk. The instruments began to work non-stop. They have been analysing the density, composition, type of radiation, and intensity of matter, and then packing them up and sending them back to Earth.

But the most critical breakthrough has yet to be found. Scientists have long hoped that the Star Ocean spacecraft could discover some macroscopic objects here, such as interstellar dust with a diameter of more than a centimeter, and then one day bring them back to Earth for study.

At this moment, it has been several years since the last awakening of the Star Ocean spacecraft. In the meantime, it has continued to move forward. Now the distance between it and the sun has expanded to 1.5 trillion kilometers.

While most of its equipment has been shut down, some important equipment is still in operation. These include four large optical telescopes mounted on the outer walls of its cabin. They are constantly collecting the light transmitted from the empty cosmic space around them, and then transmitting this data to Ye Luo. Further analysis was carried out by the leaf falls.

This work has been going on for more than ten years, and until now, nothing has been found. But today it seems to be a little different. Through the faint reflection of starlight, a telescope captures a faint bright spot in deep space. This bright spot quickly caught Ye Luo's attention, and then the four telescopes adjusted their angles at the same time, aiming at the point of light at the same time.

Further analysis was soon forthcoming. The data showed that the point of light came from an irregular asteroid about 17 meters in diameter about 200 million kilometers away. Its composition is currently unresolved, but its surface is very bright and has a very high albedo. This suggests that its surface may be made of water ice, dry ice, or methane ice.

The library of the leaf drop stores programs on how to deal with this situation. Here is a huge cavity between the ecliptic discrete disk and the Oort cloud region. It has been thought to be empty for hundreds of years, but if you could find a star here and analyze it. Many of the problems facing human civilization may be answered.

This is a very important scientific discovery, so after a little calculation, Ye Luo decided to capture this asteroid, even if he can't catch this asteroid, he has to find a way to send it to get some substance. But in this vast space, especially when the Xinghai spacecraft is in a state of high-speed motion, it is not easy to capture this star.

The farther a star is from the Sun, the slower it will be, and within the speed of the spacecraft, it can even be approximated as being stationary relative to the Sun. It is not a simple task for a spaceship moving at a speed of 3,000 kilometers per second to capture a stationary object. You must know that under such high speed, if the Xinghai spacecraft crashes directly into the asteroid, the huge kinetic energy brought by the high speed may destroy the entire spacecraft.

But before setting off, the engineers who built the ship had already taken this situation into account, and they had devised a well-developed plan to capture the stars they encountered or obtain the material on the stars they encountered.

In this silence, a certain part of the cabin of the Xinghai spaceship, which had turned into cold stones in the universe, slowly opened. Something resembling the barrel of a machine gun gradually stretched out. With four large optical telescopes as eyes, the orbit and position parameters of the irregular asteroid are continuously transmitted to the central processing unit of Ye Luo, and Ye Luo uses these data as the basis for adjusting the angle of the gun barrel until it firmly locks on the irregular asteroid.

And then it fired a bullet. The velocity of this bullet is 100 kilometers per second, and because the relativistic effect of a moving object is very weak in a low-speed state of motion, its velocity at this moment is a simple superposition of the velocity of the chamber and the speed of the spacecraft, that is, 3,100 kilometers per second.

It was heading at 3,100 kilometers per second towards the irregular asteroid 200 million kilometers away, and it was expected to hit the irregular asteroid in 18 hours.

After the bullet was fired, another thing was fired from the cabin of the Star Ocean spacecraft. When the thing was unfolded, it showed its true form - it was a huge disc-shaped thing with an outer layer of metal and a huge filter on the inside. It is more than a dozen meters in diameter and less than five centimeters thick. On top of its metal rings are also equipped with more than a dozen miniature engines. Propelled by these tiny engines, the strainer followed the bullet towards the irregular asteroid.

A total of five units of this filter were launched. Clearly, Leaf Fall intended to smash the asteroid first, and then use the filter to capture the tiny dust particles scattered in space. Although the filters still have speeds of more than 3,000 kilometers per second relative to asteroid debris, their screen structure is extremely strong, and they are fully capable of catching tiny star fragments. They also have their own power, which means that after capturing the stellar fragments, they can return to the Star Ocean and bring those things with them.

The entire capture process lasted more than thirty hours, and everything was just like the preset in the Leaf Drop program database, the bullet first shattered the asteroid, and then the filter that followed captured a large number of star fragments, and then successfully returned to the spacecraft. Before entering the spaceship, Ye Luo perfectly sealed these precious interstellar materials and stored them in the warehouse.

It does not have the authority to detect these interstellar materials on its own, and it needs to wait until Wei Feng wakes up before it can analyze them under Wei Feng's command.

This was the only thing worth describing during this ten-year hibernation, and after this incident, the Star Ocean spacecraft regained its tranquility once again. It still floats like a cold stone in the infinite vastness of the universe until a certain point in time comes.

The pressurized equipment is turned on, the temperature control equipment is turned on, the gas circulation equipment is turned on, the related life-sustaining equipment is turned on, the lighting equipment is turned on, and the thawing process begins...... Awaken......

"Hello, Captain, and welcome to the world ten years from now." Ye Luo said to Wei Feng.

Wei Feng opened his eyes with some difficulty, and got up from the hibernation pod slightly awkwardly, still putting on his clothes as if he was waking up for the first time, replenishing some water, and then it took a long time to slowly adapt to the environment here.

"How many parts have broken down in those 10 years? How many bugs have you accumulated? Are there any instructions from the Earth? You...... Did you encounter any unexpected situations? ”

"There are seventeen parts that you need to repair and replace. I've accumulated forty-five small bugs, and seventeen announcements have reached me from the earth, is there any emergency...... There's one thing. ”

Wei Feng was slightly surprised: "What kind of emergency is it?" ”

"Four years ago I observed an asteroid and smashed it with a bullet, then I captured some of the material on it and transported it back to the spacecraft and sealed it." Ye Luo replied, "I don't have the authority to test them, I've been waiting for you to wake up. But...... During the transportation process, I noticed that there seemed to be something unusual in it through the simplest optical sensor. I think it's best to analyze it as soon as possible. (To be continued......)
