The valley has returned to its former calm, and Liang Zheng's tomb has been resealed, and perhaps many years later, when the grass and trees here cover it again, and the wind-blown earth completely covers the stone houses below, no one will notice that there is such a secret under this low mound, and this native, who was lucky enough to meet the natives of different civilizations, is sleeping here.

In the low-earth orbit of the living planet, the Pioneer spacecraft began to start its engine, Su Yichen and they had returned to the spacecraft from the ground, and the search for information on this planet had been completed, and there was no point in staying any longer, not to mention, because of Liang Zheng's record, they accidentally got a message in this place, that is, the information of an unknown civilization that had been here.

In the valley, they found Liang Zheng's grave, which had nothing to gain except another piece of stubborn iron. In addition, they searched the valley in detail to find traces of the unknown civilization, but unfortunately, perhaps for too long, all traces were destroyed and covered by natural growth, and disappeared without a trace.

It must be said that this is a pity. But no matter what, they still have a lot to gain in this living planet. In particular, Liang Zheng's record confirmed the correctness of Ike's visit to the Andromeda Galaxy, which does have a high-dimensional remnant area, and even information about the life of civilizations in this area.

However, they still have no idea where this place is, and they can't know the more detailed situation, so they can't deduce the specific location of this area. The Andromeda Galaxy is an extremely large galaxy, its vastness comparable to that of the Milky Way, and it is even more difficult to find a small place in such a huge area than to find a needle in a haystack.

In addition, they were given two Diehards, which they analyzed when they returned to the Pioneer spacecraft. The results of the analysis were somewhat unexpected, and the instrument showed that the two iron-looking objects were actually iron, but it was hollow, and the most central part was empty, so the weight in the hand was much lighter than that of ordinary iron.

When they learned that their interior was hollow, Su Yichen and Luo Yan's first thought was to wonder if there was any secret hidden inside the hollow. Actually, it's not just him. Ramon. Anthony thinks the same way, knowing that there are many novels on Earth that have plots like this, and some confidential things are hidden inside an object that seems impossible to hide. Among these novels, for the former Chinese, the most famous is of course a martial arts novel written by the Jin Daxia, this novel called "Relying on the Sky to Slay the Dragon" describes such a plot, two divine soldiers regarded as treasures by martial arts people caused one catastrophe and competition after another in the martial arts, and everyone was killed by the sentence "Martial arts supreme, treasure sword slaying dragon." Command the world, don't dare not obey, rely on the sky and don't come out, who is in the front", but the people who compete for these two divine weapons do not know that their real value does not lie in the sharpness of these two divine soldiers, but in the sword body and sword body of the divine soldier There is a huge secret hidden.

This story was almost unknown in the late 20th century to the beginning of the 21st century. There have been a lot of film and television changes. Although this is just a plot in a novel, there is a similar situation in reality. For example, some special tools used by spies to hide intelligence, although they are different in size, their functions are the same, they can seal things that need to be hidden inside without outsiders knowing.

It is precisely because of this that Su Yichen naturally thinks so, and it is even a little excited. I think that since there is a vacant space inside these two stubborn irons, will they hide some secrets?

Unfortunately, the answer is not so, and Ike's analysis clearly tells them that it was scanned by the instrument. Its interior is hollow, but there is nothing to hide. And there is another thing that everyone is puzzled by, that is, the instrument also shows that the hollow state of these two stubborn irons is very bizarre, they are not specially processed, because there are no traces of other processing on the stubborn iron except ordinary polishing, and the hollow parts inside are not deliberately made, as if they are naturally formed.

"It should be easy, when casting, a blank area is formed on the inside, and then the outside is formed by melting molten iron." Ramon. Seeing Su Yichen's puzzled looks, Anthony said a little assumedly.

Su Yichen shook his head, of course he knew this. In fact, there is a simpler way, which is to use the same material to hollow out the center first, and then pour the seal with molten iron on the outside, so that a similar situation can be formed. But the problem is that either way, although it is difficult to distinguish with the naked eye, these traces are easy to find under the scanning of the advanced instruments and equipment on the Pioneer spacecraft.

Now, Ike's scans have found no such traces, which means that the formation of these two pieces of stubborn iron is completely natural, and then the surface is polished by humans. This is very strange, with the characteristics of iron, natural formation is absolutely impossible, even if the evolution of nature has caused such a miracle, but the internal void will inevitably produce such traces.

Now, they found no such traces, and upon perspective, the inside of the stubborn iron was very smooth and flat, as if they had cut a piece of space out of thin air inside a whole piece of something, and then reclaimed it without destroying its surface.

Ike couldn't help but look at Su Wei at this moment, because he thought of Su Wei's ability. Su Wei is an intelligent life, but his intelligent life has a strange spatial ability. He can shuttle and stay in a certain space, or he can directly take the things inside through the power of space without destroying the items.

"If I give you a piece of iron like this, will you be able to get out of the space inside without destroying its outer structure?" Ike asked Su Wei.

Su Wei took a piece of stubborn iron and looked at it, then thought about it carefully, shook his head and said, "I can't do it." ”

"Can't do it?" Ike asked repeatedly.

Su Wei nodded: "Yes, I can't do it, this space is too small, and it is very difficult for you to ask to dig out such a small space directly inside the iron object." If it was bigger, I might have tried it, but something as small as this. I'll ....... ”

Ike raised his hand to stop Su Wei from continuing, he thought about it and asked, "Then you tell me, if your ability goes further, or doesn't consider the limitations of your ability, just based on the characteristics of your ability, how is it possible to do this?" ”

Su Wei replied without hesitation: "One hundred percent." Of course, this does not take into account the limited aspects of my abilities, but only theoretically. ”

Hearing this, Ike immediately laughed, he looked up to the sky and laughed, Su Wei gave them a satisfactory answer, he can now determine the origin of these two pieces of stubborn iron, they must have been brought by Liang Zheng from the so-called Divine Domain, as for who made them like this, it is unknown.

Ike's judgment is just a judgment, and no one knows whether it is the truth or not. But for Ike, this judgment is extremely likely. Now, there was only one question before them, and that was where the unknown civilization was located, and Ike couldn't answer it.

Based on the life planet they landed on, Ike calculated according to the time when Liang Zheng left, of course, this time is very inaccurate, but the information they obtained can only be so. The Pioneer spacecraft's powerful brain system calculates according to Ike's requirements. Three range answers are then given. There is a huge difference in the radius distance between the answers to these three ranges, which are the range of navigation due to normal curvature speed, jump speed, and possible error due to time difference.

When the three range answers come out. Ike skimmed some more areas from it, and the reason for doing so was because Ike considered the location of Liang Zheng's living planet in the Andromeda galaxy. They came to the Andromeda Galaxy from the distant Milky Way, and this living planet was the first living planet with civilization they came into contact with. It can also be concluded that at the angle they came, including near the edge and outer regions of the Andromeda Galaxy, the possibility of the existence of an unknown civilization is extremely small.

To know. The Pioneer spacecraft is a spaceship built by the highest technology of the Rand civilization to sail across large galaxies, and its performance and the functions of the brain system, including the ability to search the surrounding area during the voyage, are incomparable to ordinary spaceships. Again, according to normal inference. The possible location of the unknown civilization should be based on the internal direction of the Andromeda Galaxy, so Ike asked Zhi Brain to demarcate several key areas for reference.

"With such a large area, if you want to search everywhere, it will take ...... time." Su Yichen frowned and looked at the search range plan that Ike finally came up with. According to the calculation and division of the focus area, although it is much smaller than the results of the previous preliminary calculations, it is still an extremely vast universe for them.

If you compare the size of the Pioneer spacecraft, this vast universe is even much larger than a small ship on Earth compared to the sea. If they want to complete the search, the time it takes them will definitely not be able to complete it in a few years, maybe it will be decades or even hundreds of years of searching, and if they are unlucky, they may not be able to find each other after all the searches.

"What's better for you?" Ike understood what Su Yichen was referring to, and he asked helplessly.

Su Yichen didn't answer, but his attitude had already told Ike his own answer. Oh, yes! Apart from this method, what better way can he do in the vast universe? Although this method seems stupid, it is the simplest and most direct way, and in the current situation, they can only try their luck according to this method.

In the end, no one knows what luck will be. The Pioneer spacecraft finally left the planet where Liang Zheng lived, heading towards the unknown starry sky ahead, and in the coming days, they would continue to expand their search according to the division of the search area, which would be a very boring journey, but it was also a journey that everyone expected to have a miracle.

Time passed quickly, one, two, three, four, five days ....... January, February, March, April, May, ....... One-year, two-year, three-year, four-year, five-year .......

By the time the sixth year came, they had spent five years searching for the aimless area. In the past five years, they have been a long distance away from Liang Zheng's life planet, but until now, they have found nothing, and they just continue to search according to the itinerary plan every day, expand the range, and search again...... Nothing more.

Ramon. Anthony sat on the bridge, and over the past five years, he had gradually become a qualified astronaut from a beginner in operating the ship. And in the course of these five years, Raymond. Anthony is also learning and improving, and although he is still not a scientist, his relative knowledge has improved a lot compared to before.

Looking away from the three-dimensional projection in front of him, Raymond. Anthony glanced at Su Wei who was not far from him, Su Wei was an intelligent life, and he was also a member of the spacecraft, in order to ensure that there would be no omissions in the search, Su Wei's main job was to assist the spacecraft's intelligent brain system to review the search process.

Actually, this is not very useful, but Ike still asks Su Wei so much, and Su Wei has always done a good job.

Sighing lightly, Raymond. Anthony felt a little bored, but he had long been bored. How can it not be boring for everyone to repeat such a monotonous job almost every day? Of course, this kind of words Raymond. Anthony would never say it to anyone, but quietly hid it in his heart. What he hopes most now is to find that civilization as soon as possible, and to end this tedious life of sailing as soon as possible.

"There's a discovery!" At this moment, Su Wei suddenly shouted, and at the same time, the spaceship's intelligent brain system also sent out a prompt. Ramon. Anthony was stunned for a moment, then immediately looked back at the three-dimensional image that was displayed.

When he saw what was shown in the three-dimensional image, Raymond. Anthony couldn't help but be ecstatic in an instant, because at this time he saw a spaceship, a spaceship! In the universe, what does it mean to discover a spaceship? This of course means that they have met a cosmic civilization. Perhaps, this cosmic civilization is the unknown civilization they have been looking for. Anthony immediately jumped to his feet and couldn't wait to send an urgent message to Ike and Su Yichen.
