Su Yichen and the others never thought that they would suddenly pass such a long distance from the edge of the Milky Way near the edge of the solar system, 2 million light years, which is an almost terrifying number, and it would take at least millions of years to go back in such a long distance, even if they sailed in curvature.

A wormhole that inexplicably appeared in front of them made everyone on the Vanguard spacecraft actually leave the star where they were and came to the distant Andromeda Galaxy, and even such a long distance only took them a short 5 seconds before and after, and for a while, everyone's expressions froze on their faces, and no one was speechless.

Wormholes are an extremely unique celestial phenomenon, and even the higher civilizations of the universe have not understood its mysteries 100%, and even whether wormholes really exist in the universe cannot be confirmed. In fact, from the perspective of some characteristics of wormholes, the transition technology is somewhat similar to wormholes, and the difference between them is very great when compared from the actual situation.

According to the core of curvature technology, its main role is to straighten the space in front of the aircraft, and then reach or even exceed the speed of light through space retraction. The transition technology uses the foldability of space to make the three-dimensional space transform into two-dimensional space to a certain extent, so that one point can reach another point in the shortest time.

It is precisely because of this characteristic that the jump technique is also called the folding leap technique, but it is very different from the wormhole. You must know that the wormhole has another name: the time hole, which is a multi-dimensional space tunnel, in which each dimension and space has undergone another strange change, and its properties are very different from ordinary transition techniques.

Even, Su Yichen is doubting in his heart now. Through the wormhole, they inexplicably came to the Andromeda galaxy, and now the timeline is still in its original position. Although various data show that they only spent a short time of 5 seconds through the wormhole, it is necessary to know that the internal dimension and time and space of the wormhole are completely different, perhaps in this short moment, everyone in the Pioneer spacecraft has not only crossed a long distance, but even spanned a long time, as for whether this time is forward or backward? This is an unsolvable answer. Because they can only figure this out if they return to the Milky Way, to the galaxy they are familiar with, and to connect with their own civilization or with other cosmic civilizations.

When he understood his situation, everyone couldn't help but despair after a long silence, especially Tang Le, who was still a little excited just now, and when he understood what he was facing, his whole face showed an expression of wanting to cry without tears. At a distance of 2 million light years, not to mention this Pioneer spaceship, even the most advanced spacecraft of the Blue Star civilization will not be able to return to its home planet in a million years. Even. There is no cosmic civilization in the entire galaxy that can do this, and even if it pilots the jump ship of a higher cosmic civilization, then such a long distance will take at least tens of thousands or even hundreds of thousands of years.

In other words, all of them have become wanderers in the universe, people who can never return home. Thinking of his own civilization, thinking of his home planet, and even thinking of his relatives, Tang Le, who has always been optimistic, even shed tears. I couldn't help but sob.

As for Gao Jian's heart, the same is true, although he is still strong on the surface. But the loss and despair in my heart are no less than those of Tang Le. His relatives on the earth are still waiting for him to go back, but now even if he spends his life on earth, he can't return to the earth, a sense of loneliness and loss of being abandoned and isolated is thick in his heart, Gao Jian pursed his mouth vigorously and clenched his hands tightly.

Kevin. Adams is slightly better. After all, his age and experience have made him more tolerant, not to mention that he is a more persistent scientist, although he also has shock and panic in his heart, but he soon gradually calmed down.

Su Yichen looked at Luo Yan beside him with a wry smile and regret, and at this moment, Luo Yan also looked at him. Moment. Both sides read the words in their eyes, and they can no longer return to the familiar earth, nor can they fulfill their respective promises, and even can no longer see those relatives and friends on the earth, and the loss and despair in their hearts cannot be concealed. But in any case, they are still together, and although they are so far away from the earth, at least this is the only thing that can comfort each other.

"I'm sorry, it's my fault, if it weren't for my insistence on rushing back to the solar system, maybe ......."

As the captain, Su Yichen took the initiative to stand up and take responsibility, in his opinion, if he hadn't ordered the Pioneer spacecraft to rush back to the solar system as quickly as possible, and even vetoed the proposal to stop for a short overhaul halfway, then maybe they wouldn't have encountered a wormhole and appeared in this place.

"Nope! It's not your fault, you're our captain, it's just an accident, though an unbelievable ....... Who would have thought that Tang Le, who was wiping his tears, shook his head instead, his sad look was full of firmness, and he took the initiative to say: "Maybe we are the only intelligent life in the entire galaxy that has passed through the wormhole, which is a rare experience for us." I think we can try to find out that maybe wormholes still exist in the universe, if we go through again, maybe we can go back. ”

"What if you can't find it? What if you can't go back? Gao Jian couldn't help but ask, as soon as his words came out, he felt that something was wrong, and quickly closed his mouth, his face full of apologies.

"What if you can't find it? Isn't being part of a civilization in a strange galaxy a test of exploring the mysteries of the universe? Even if our lives end in the future, I think one day our experiences will be passed back to our respective civilizations. ”

"Maybe you don't have to be so pessimistic." Kevin. Adams said: "Accidents have already happened, and it is useless to hold them accountable, especially if it is through a wormhole or coming here by accident, as Downer said, it is a valuable asset to our respective civilizations." Maybe we'll be able to find our way home, find another wormhole that we can go back to, and even if we can't, with the equipment of our Vanguard spacecraft, we'll be able to hibernate, hibernate if necessary, and in that case, the long hours and distances may be just a sleep for us. ”

"That's right! That's a good suggestion. Donle's eyes lit up, Kevin. Adams' words reminded him. The Pioneer spacecraft has a well-developed ecological circulation system, coupled with hibernation equipment, which allows them to have almost endless life. At that time, they can hand over the spaceship to Zhizhi or Su Li to pilot, and everyone will go into hibernation, so that no matter how far away it is, it is theoretically achievable, no matter how long it takes to wait for the time to go back. At least there's hope, isn't it?

Gao Jian thought about this suggestion and immediately agreed, while Su Yichen and Luo Yan nodded in agreement, but in fact, they knew in their hearts that although this was theoretically possible, no one could guarantee whether it could actually be realized. After all, nearly a million years is too long, and who knows what will happen to them during a voyage of 2 million light-years or more? But in the face of the current situation, these words can only be hidden in the heart.

The crowd temporarily recovered from the cruelty of reality and threw themselves into the long journey home. Now, there is no point in thinking about the crisis of the earth's civilization. Su Yichen only hopes that the earth civilization can see through the conspiracy of the Gaia civilization, so as to preserve the independence and development of the civilization.

Another thing that made Su Yichen feel at ease was that the medium-sized spaceship of the Blue Star Civilization did not seem to have crossed the wormhole with them, after all, there was still some distance between the two sides at that time, the Pioneer spaceship was passing towards the front of the wormhole, while the medium-sized spaceship of the Blue Star Civilization, which was some distance away from them, was on the other side, plus the medium-sized spaceship was much more advanced than the Pioneer spaceship in terms of power and technology. Then from the final result, it can be inferred that the Pioneer spacecraft did not get rid of the attraction of the wormhole and led to the crossing. However, the medium-sized spaceship of the Blue Star Civilization is likely to have escaped the curvature navigation state in time and avoided the wormhole. If that's the case, then at least the medium-sized ships of the Blue Star civilization have been preserved. They can still go to the solar system to visit the Earth civilization while waiting for the Pioneer spacecraft to no avail. With the help of the Blue Star Civilization, the Earth Civilization will have a much better chance of survival, and it will also bring the news of their disappearance back to Earth.

Of course, this is just Su Yichen's speculation, but according to his judgment, the possibility of this guess is very high. The rest of the time, the Pioneer spacecraft tries to look for the shadow of the wormhole behind the voyage. According to the results of their discussion, since they traveled from one end of the wormhole to the other, it can be inferred that the wormhole is still behind them, and perhaps they can return to the galaxy by finding this wormhole and crossing it again.

Unfortunately, this is nothing more than a corollary. When the Pioneer spacecraft turned its head in the universe, flew in the opposite direction of the flight, and even took the initiative to start the curvature engine again to find the mysterious wormhole, this wormhole never appeared again, no matter what method they used in common sense, there was no difference between space and usual, still endless void and stars full of universe.

Everyone worked hard for more than three months, constantly searching for this airspace, but there was still no shadow of a wormhole. It was as if the wormhole they had traveled through had inexplicably disappeared, as if the wormhole had never existed.

This result made everyone a little dismayed, which means that the possibility of returning to the galaxy by finding the wormhole is almost non-existent, and the only way left is to fly towards the galaxy in curvature.

The road is long and full of unknown dangers, but it is their only option. After positioning the galaxy by Su Li and the spacecraft's brain, a direction for the return route was finally selected after precise calculations. After making preparations, the Pioneer spacecraft once again entered a curvature range and headed for the distant galaxy.

More than 20 days later, the Pioneer spacecraft broke away from its curvature, but its direction did not change in the slightest. And this time it is also necessary to detach, you must know that the location where they are now is the Andromeda Galaxy, a galaxy that has never been involved in any earth civilization, even the Blue Star civilization, including the cosmic civilization of the galaxy higher than the Blue Star civilization, and everything in front of them is completely unfamiliar, and there is no so-called star map to refer to.

In this case, in order to ensure the safety of curvature navigation, it is necessary for Su Li and the spaceship to calculate and plan the road ahead in advance, and according to Su Li's maximum calculation and planning ability, it can only do about 25 days of curvature navigation, once this distance is exceeded, then the danger of the Pioneer spacecraft in the curvature navigation state will be greatly increased.

Of course, it is not completely impossible to increase the degree of computation, but as the distance increases, the amount of calculation and the difficulty of calculation increases exponentially, in contrast, this way of flying is the most efficient, not to mention that the Pioneer spacecraft is facing a long distance of up to 2 million light years, and the performance and maintenance of the spacecraft are also extremely important, which is the reason for the final choice of this solution.

A few days later, after the results of the next flight data were completed and the equipment inspection of the Pioneer spacecraft was also ensured, Su Yichen and the others once again entered the curvature navigation state, and after more than 20 days, like last time, the Pioneer spacecraft once again broke away from the curvature state and continued to prepare flight data and test the spacecraft again.

Time passed quickly, and now half a year had passed since they crossed the wormhole, and three months had passed on the return journey. In the past three months, the Pioneer spacecraft has made three curvature flights, and has also experienced three disengagement and monitoring, and now it is preparing for the calculation of the fourth curvature flight data, according to the normal situation, the work of Su Li and Zhi Brain can be completed in two days.

But who would have thought that at this time, Su Li suddenly took the initiative to summon everyone in the Pioneer spaceship, just when Su Yichen thought that the flight data had come out in advance, Su Li clicked on a three-dimensional star map, pointed to a small galaxy 6 degrees in front of them, and said something that everyone felt incredible.

"What do you say? Is there a living planet over there? ”

Su Yichen was shocked at first, and then he was happy, he never thought that he would find a life planet on the way back, could it be that they ran into the cosmic civilization of the Andromeda Galaxy? If the other party is a high-level cosmic civilization, maybe they can get some help on the other side, if the other party's civilization is only a low-level or medium-level cosmic civilization, then it doesn't matter, at least they can get the star map of this strange galaxy from the other party!

When thinking of these possibilities, not only Su Yichen, but everyone else couldn't help but show an expression of extreme joy on their faces. (To be continued......)
