From Explorer 8, Yang Peiqi already knew that spaceships were generally divided into ten levels. The lowest level is a Tier 9 ship, while the highest is a Tier 1 ship. Among them, the ninth to seventh spaceships are also called low-level spaceships, the sixth to fourth levels are called intermediate spaceships, the third to first level are called high-level spaceships, and the top special spaceships.

These spacecraft are graded according to their speed. A Class 9 spaceship that can reach a thousandth of a speed of light, an eighth-level spaceship that can reach one hundredth of a speed of light, and a seventh-level spaceship that can reach one-tenth of the speed of light. All three types of spaceships are low-level spaceships.

And if you want to cross the threshold of an intermediate spaceship, you must be able to reach at least the speed of light. The division of medium-level spaceships is no longer about increasing speed by a factor of ten, but much less, which is related to the difficulty of spaceships trying to increase their speed after they reach the speed of light. a sixth-level spacecraft capable of reaching 1-2 times the speed of light; The ones that can reach 2-3 times the speed of light are the fifth-level spacecraft; Those that can reach 3-5 times the speed of light are fourth-class spacecraft.

The hallmark of a high-level spaceship is the ability to make space jumps. Moreover, the speed class difference between high-level spaceships is also much greater than that of medium-level spaceships. A spacecraft that can reach 5-10 times the speed of light and can make space jumps is a third-class spacecraft; A spaceship that can reach 10-20 times the speed of light and has space jump energy is a second-class spaceship; Spaceships that can travel faster than 20 times the speed of light and have the energy to jump in space are classified as Class 1 spaceships.

As for the super-class spacecraft, their logo is even more perverted. The characteristic of this spacecraft is that it is capable of trans-space flight. That is, if a spaceship does not have the ability to pass through the cosmic crystal wall. No matter how fast it is, it can only be counted as a first-class spaceship.

Of course. If a spaceship has the ability to pass through the cosmic crystal wall, even if its speed is only the flight speed of an ordinary aircraft, it is still a super-class spaceship.

Explorer VIII is a super-class spacecraft, because the Eskett civilization originally developed it to travel across the space and explore for mineral deposits.

Yang Peiqi exchanged huàn's two spaceships, the first, which Yang Peiqi is riding at this moment, flying fast at a low altitude on Mars to explore Martian mineral deposits. It is a seventh-level spaceship, and the second one, that is, the spaceship that Yang Peiqi specially exchanged for this space trip, is a third-level spaceship.

In the storage space of Explorer 8, the lowest-level spaceship is a level 7 spaceship, and as for the lower-level 9 spaceship and level 8 spaceship, Explorer 8 has limited storage space and will not carry this garbage. As the lowest-class spaceship, this is also the cheapest of the spaceships it carries. Requires 100 million energy points. The sixth-level spaceship above requires 300 million energy points, the fifth-level spaceship needs 400 million energy points, and the fourth-level spaceship needs 500 million energy points.

You can see it from here as well. The gap between the third-level spaceship and the fourth-level spaceship is gone. In terms of price alone, the difference between the two is fully doubled. And this is still the price given by Explorer 8, if you really go to other high-level civilizations to buy it. The price is much higher.

Originally, Yang Peiqi was after hearing Explorer 8 say that the Zeta universe he was in was just a low-level universe. I thought that even if there were other civilizations in this universe, they would be just low-level civilizations. It's about the same as the Earth, even if it's higher, it's definitely very limited.

However, now Yang Peiqi doesn't think so. Because in front of him, a spaceship of no lower level than level six appeared, which was an intermediate spaceship with the ability to fly faster than the speed of light. And today's most advanced spacecraft on Earth has a maximum speed of less than one thousandth of the speed of light, that is, it is not even a ninth-level spaceship.

In fact, according to the spacecraft level of the Eskett civilization, the spacecraft owned by the countries of the earth, whether it is a space shuttle or a spaceship, do not have full space flight capabilities. With the current level of science and technology on the earth and the speed of technological development, it is unlikely that a spaceship with the ability to fly faster than the speed of light will be built within a hundred years.

Perhaps, in the eyes of the civilization where the spaceship in front of you is located, today's earth civilization is similar to a primitive society. If this civilization wants to invade the earth, the earth will not be able to parry it at all.

"I don't know if the Earth was discovered when this spaceship crashed?" Yang Peiqi thought secretly in her heart.

"If you're sure it's a good question, just check it out." Explorer Eight said very lightly.

Yang Peiqi shook his head and said, "It's all ruined like this, and there's no point in going up." ”

"Not necessarily." Explorer 8 said, "With my current capabilities, I can't guarantee anything else, but it's not difficult to find out if the ship sent out a distress signal at the last moment before it crashed, or even the content of those distress signals." ”

Yang Peiqi was stunned for a moment and asked, "What you said is true?" ”

"What did I lie to you?" Explorer Eight said disdainfully.

"Alright, let's go down and have a look." Yang Peiqi gritted her teeth and said.

Soon, the craft landed near the crashed unidentified spaceship. The hatch opened, and Yang Peiqi asked Explorer 8 to open the energy shield, and left the aircraft with a team of super machine bodyguards, and walked beyond the crashed spaceship.

Yang Peiqi didn't have any spacesuit on him, and the energy shield that Explorer 8 had opened was much more effective than any spacesuit.

As for those super machine bodyguards, there is no obstacle at all to walk on Mars, and they don't need to breathe oxygen. Because they are not real human beings at all, but highly intelligent people.

Because the place where the aircraft stopped was very close to the crashed spaceship, it didn't take much time for Yang Peiqi and the others to board the crashed unknown spaceship.

Although the ship has crashed, and in the process of crashing, it has also produced a violent combustion due to friction with the Martian atmosphere, but. Yang Peiqi can still understand the situation of the spaceship and guess some of the situation of this ship.

It's obvious. This universe was very much more advanced than the seventh-level spaceship he was on. Explorer VIII said that the spacecraft was at least a sixth-level spacecraft, which was obviously a very correct guess.

After entering an unidentified spaceship. Explorer 8 quickly told Yang Peiqi that this unknown spaceship was a sixth-level spaceship, but it was not an ordinary sixth-level spaceship, but a top-level sixth-level spaceship. The top speed of this spacecraft is infinitely close to twice the speed of light.

However, Explorer 8 told him that it had not found any signs of life on the unidentified spacecraft.

And in the process of walking towards the cockpit of this unknown spaceship, Yang Peiqi also found that the personnel on the unknown spaceship had died.

The people on board these spacecraft are a life that is distinctly different from the humans on Earth. They have very tall statures, among the bodies that Yang Peiqi saw along the way, the shortest one was more than two and a half meters, and the tallest was close to three meters.

Moreover, the bodies of these people are very strange. Maybe it's because it's been a long time, or maybe it's because the spaceship crashed into a violent fire, and all that remains of the skeleton remains. However, the color of these skeletons is different from the color of the bones of the earthlings. None of them are white, they are blue, and the blue is so beautiful that it looks like a work of art.

There were apparently quite a few people on board this unidentified spaceship. Yang Peiqi found no less than 100 bodies along the way. The bodies were of various shapes, some sitting, some running. There are also various positions such as lying down. However, most of the remains are incomplete. It was supposed to burn up during the crash of the spaceship.

Finally, Yang Peiqi came to the main control room of the spaceship. This is the brain center of this unidentified spaceship. Explorer 8 wants to find out if the unknown spacecraft sent a distress signal before it crashed, and the only way to do this is to start here.

After entering the main control room, there was nothing to do with Yang Peiqi. As for how to find out whether this unknown universe sent a distress signal before it crashed, Yang Peiqi didn't know what to do at all. He just walked around the main control room at random, leaving the investigation to Explorer Eight.

The main control room is also very spacious, with an area of no less than 100 square meters. In the main control room, Yang Peiqi also found several corpses. Yang Peiqi found that these bodies were obviously taller than those outside, the shortest were about 2.8 meters, and the tallest one was 3 meters tall. Moreover, the location of the three-meter-high body should be the location of the captain.

Yang Peiqi was wondering, is it true that the higher the status (ability) of this unknown spaceship civilization, the taller the stature?

The exploration process of Explorer 8 did not take much time, and Yang Peiqi only walked around the main control room before getting a reply from Explorer 8. It's just that this reply made him a little uneasy.

"The spacecraft sent back a signal before it crashed." These were the first words of Explorer Eight. However, it was this sentence that made Yang Peiqi's heart beat violently. Because once the civilization to which the unknown spaceship belongs receives the signal sent back by the spaceship, it may come to check on the situation of the spaceship. Therefore, even if the spaceship does not mention the news of the Earth in the signal sent back, as long as other spaceships that come to search for this spaceship come, the Earth will definitely be exposed to the sight of this civilization.

And once that unknown civilization has any idea about the earth, then the earth is really dangerous. In the face of the powerful scientific and technological power of that unknown civilization, the earth has no resistance at all. Unless, he was able to repair Explorer 8, completely unlock Explorer 8's storage, and obtain the advanced weapons that Explorer 8 carried.

However, in the current situation of Explorer 8, this will be very difficult, because of Yan Zòng's trauma, the storage space of Explorer 8, especially the weapons storage space, is greatly limited, and it is impossible to obtain those advanced weapons.

By now, Yang Peiqi already knows that the storage space of Explorer 8 is divided into several parts, one of which is used to store material samples. Once it detects high-grade matter somewhere in the Infinite Universe, it will take samples and put them into this space for detailed analysis when it returns to the Eskett civilization to see if it is necessary to mine it. The second part is the energy storage space, which stores the energy needed for the Explorer 8 main Special Classcraft and the other vehicles it carries. The third part is the storage space for some ordinary materials, which stores some of the daily necessities and supplies of the crew who went to other universes with Explorer 8 to explore. And the last part is the weapon storage space.

When Explorer 8 passed through the black hole, it encountered a space storm, and this powerful space storm destroyed the main body of Explorer 8, and the crew inside, including the owner of Explorer 8 at the time, that is, the captain of Explorer 8, all died and entered the black hole. The main body of Explorer 8 was destroyed, and its separate storage space was partially damaged. Among them, the storage space of living materials has been completely destroyed, the storage space of mineral deposits has been partially damaged, and the storage space of energy and weapons has been blocked, although it has not been damaged. After Explorer 8 wakes up, only partially open these two spaces. And what it can take out are all low-level or low-privilege items.

To fully open these two spaces, it would take a lot of time to restore Explorer VIII on Dù. This is a big way, that is, at least 30% of the damage to Explorer 8 needs to be repaired, and now, Explorer 8's wounds are only less than 5% repaired, which is still far from it.

The main thing is that if you want to further repair Explorer Eight, you can't just use some low-grade substance. Otherwise, with the mineral deposits that Yang Peiqi found on Earth, the Moon and Mars, it would be more than enough to restore Explorer 8. After all, the mineral deposits discovered by Yang Peiqi on these three planets are calculated in trillions of tons.

In a word, if you want to further repair the wounds of Explorer 8, it is no longer a simple accumulation of mineral deposits, but a qualitative improvement. According to Explorer 8, it is necessary to discover at least intermediate substances, that is, substances above level 6. This is not something that can be done with the material that the solar system itself has. (To be continued......)
