The curvature engine was forcibly terminated, a protective measure for the brain system, but this protection was never activated since the construction of the Pioneer spacecraft was completed. Even though Su Yichen and the others were pursued by two unknown civilizations on their way to the Red and Dark Nebula, the curvature engine of the spaceship was still running well.

In terms of jump engines, the Pioneer spacecraft is no match for Ike's, let alone the Homeland spacecraft. After all, they have not mastered the jump technology for a long time, and the jump engine now installed on the spacecraft is only a rudimentary jump, not a real mature product.

But the curvature engine is different, you must know that when building the Pioneer spacecraft, the earth civilization has mastered the curvature technology, and more importantly, the curvature engine of the Pioneer spacecraft is completely copied according to the curvature engine of the Homeland spacecraft, both its technology and the materials used in the construction of the engine are the most sophisticated, and in the actual process of sailing, the stability and reliability of the curvature engine have also been verified.

But now, Su Yichen and the others never thought that the curvature engine, which they regarded as absolutely unproblematic, would actually activate the termination protection measures, which was simply incredible. After the engine was terminated, Su Yichen and the others immediately checked the curvature engine, and at the same time looked for the reason for the activation of the protective measures, and soon the reason was found, and when the result was placed in front of them, everyone couldn't help but look at each other.

The curvature engine was terminated for a simple reason, not because of the engine itself, the curvature engine of the Vanguard spacecraft was intact and it was running without any problems. Crucially, the reason why the protection was activated was because it was impossible to capture the curvature in space, so the protection was suddenly activated and the engine was turned off.

When he saw this result, Su Yichen's first reaction was absolutely impossible. You must know that in the universe, there are changes in curvature everywhere. It is precisely because of the generation of these curvatures that the curvature engine can capture the curvature motion under the control of the intelligent brain, so as to use the curvature to achieve a state of flight beyond the speed of light.

And now, the results actually tell them that the curvature engine and the brain system can't capture the curvature in space, how is this possible? This result is like someone telling Su Yichen that it is ridiculous that he can't find a drop of water in the ocean. However, the facts were in front of him. When he reviewed the results of the examination and confirmed it again, the answer given made him silent for a moment.

Luo Yan also looked at the result in surprise, and like Su Yichen, her first reaction was impossible. But that's what happened, and when they used the device to scan the space in space to determine if the curvature existed, the result was the same as before, although the airspace looked normal. But it doesn't have any change in curvature, which is simply weird.

Looking at each other, Su Yichen couldn't help but take a breath of cold air, where did they come? After passing through the wormhole, the ship's jump engine was useless, and now the curvature engine is also unusable, this airspace is too weird, I knew it was like this. Su Yichen will never enter the wormhole.

Now what? This question was placed in front of Su Yichen, after careful consideration. Su Yichen decided to return to the ship immediately, so as not to be completely in trouble.

However, it is not so easy to return home, and now the Pioneer spacecraft is nearly five light-years away from the wormhole behind it, and it must first cross this distance to return to the wormhole. Under normal circumstances, it would be very easy for Su Yichen and them to cross this distance, even if they didn't use the jump engine and directly use the high-speed curvature, it wouldn't take too long. But now. Will they be able to make it back?

When the order to return was given, Su Yichen decided to use the Pioneer spacecraft to approach the wormhole in a jump, and to be on the safe side, he set a jump distance of five light years, but when the jump was completed. Su Yichen and the others' hearts sank suddenly.

The distance calculation tells them that when they come out of the jump, the position they move is only 0.1 light years, which is even shorter than the distance of the third jump, of course, the distance of the first three jumps is relatively long, but the problem is that the distance traveled is too short.

"I felt the space stretching infinitely again, at the moment when we made the leap." Su Wei said with a solemn expression.

"Increase the distance!" Luo Yan's face was not good-looking at this time, she thought about it and made a suggestion. That's right, it's to increase the jump distance, according to this airspace weirdness, they only make a fuss about the original jump distance, since the movement range is actually too small, then you can increase the original set distance! For example, if the transition distance is set to 30 light years, then even if the space is stretched, they can still use the difference between the stretch and the jump distance to achieve the desired position.

After a period of rest, the Pioneer spacecraft began another jump flight, according to the previous data, this time Su Yichen positioned the distance to 30 light years, if the situation is as they imagined, then after the jump is completed, they will be within a light year distance from the wormhole, but no one thought that when this jump was completed, everyone on the Pioneer spacecraft was speechless.

"0.15 light years?" Su Yichen looked at the data in front of him with an ugly face, the jump distance of thirty light years, and the position they moved in the end was only 0.15 light years, although this distance was slightly longer than the previous distance, judging from the comparison between the jump distance and the actual distance, they walked shorter.

What's going on? Why is this happening? Why is the infinite stretch of space different every time? And from the time of the transition, it seems that the amplitude of the infinite stretch of space increases accordingly with each separation. Could it be that this airspace has a special nature that no one knows? It's as if there is an invisible god watching them from above, playing with them in this bizarre way for fun.

In order to verify, Su Yichen quickly made another jump flight, this time the positioning was still 30 light years, but the result was actually that the position they moved was only 0.09 light years, when this result came out, Su Yichen's face was difficult to see, and Luo Yan couldn't help but show a frightened expression.

"We're in big trouble." Su Yichen said heavily, he squinted at the seemingly ordinary cosmic space outside: "This place is like an infinite swamp, and we accidentally got trapped in it. Now, the space here seems to be adapting to an unknown kind of us, and this adjustment is becoming more and more targeted. I don't know if we'll be able to go back, and I don't know what the future holds, Xiaoyan, I'm sorry ....... ”

Luo Yan shook her head, she didn't say anything but held Su Yichen's hand, she knew why Su Yichen said sorry. If it weren't for his insistence, they wouldn't have gone to the Red Dark Nebula back then, and if they hadn't gone to the Red Dark Nebula, they wouldn't have been lost in the long river of time and space, and if they hadn't separated from Ike, or if they hadn't entered this wormhole, then the result would have been completely different. Now, in the face of this complicated situation, Su Yichen has no way out, and he only has deep guilt for Luo Yan in his heart.

"We still have a chance. There's hope at the slightest chance, isn't there? Luo Yan hugged her husband and encouraged in his ear, and more importantly, what if there was no chance in her heart? As long as you are with your husband, what is the difference between here and in the normal universe?

Su Yichen nodded, he took a deep breath, Luo Yan was right. They do have a chance. The wormhole is now about 4.8 light-years away, no matter how stretched the space is. As long as their jumps can still move their positions, there is still a chance to reach the wormhole.

Thinking of this, Su Yichen immediately asked Su Wei to make a calculation, and then made another jump according to the calculation, when this jump was completed, although the position they had moved was already farther away than before. The distance of 0.12 light years was reached, but Su Yi's face did not have any joy for this result, because the actual distance set by this jump was 50 light years, and from the ratio of the setting distance to the final moving distance, the stretching of space was more targeted.

The Pioneer spaceship's jump engine is not very perfect. Due to technical and material limitations, theoretically, the maximum jump distance of the Pioneer spacecraft is about 100 light years, but in fact, during the voyage, Su Yichen and his team use the jump distance is basically 50-60 light years, sometimes shorter.

This is done because of the limitations of the jump engine and because of the safety of the jump. You must know that the longer the jump distance, the greater the accident may be, not to mention that some of the equipment of the Pioneer spacecraft is not as advanced as Ike's spacecraft or the equipment of the Homeland spacecraft, about 50 light years, which is already the limit of the Pioneer spacecraft to search forward and ensure most of the safety.

Now, they are making a jump at a distance of 50 light years, but they don't expect to move only 0.12 light years, and if the stretch of this space is only fixed at this scale, then they need at least 39 jumps for the rest of the distance. But the question is, is the proportion of the stretch of space fixed? Obviously not, from the results of each jump, it is proved that with each jump, the stretching of space is more targeted, if this continues, from the mathematical aspect, then they can get infinitely close to the wormhole, but they can never reach the wormhole.

In fact, in the following days, Su Yichen and the others made several more jumps, and their jumps set distances became longer and longer, and finally reached the maximum distance range of 100 light years designed. But as expected, the result is that the proportion of their actual distance traveled is increasing, that is, the distance they travel is getting shorter and shorter. By the time of the seventh jump, the 100-light-year distance setting had only moved the Vanguard spacecraft by 300 AU.......

This distance result makes people speechless, you must know that one light year is about equal to more than 60,000 astronomical units, and 300 astronomical units are only less than 0.005 light years in light years, this distance is too different from the still long goal, Su Yichen knows very well in his heart that they have completely fallen into a predicament, whether to get out or not only God knows.

There was a problem with the jump, the curvature was unusable, but fortunately there were no problems with the normal navigation of the Pioneer spacecraft, which was at least reassuring. But the problem is that they are still more than four light-years away from the location of the wormhole, and at the speed of ordinary sailing, they will not be able to reach their destination in their lifetime.

In addition to this, there is another issue that needs to be considered, and that is how long wormholes exist. More than a month has passed since they came to this place through the wormhole, and although the wormhole is still there, it will disappear anytime and anywhere. Once this wormhole disappears, Su Yichen and Luo Yan will never be able to leave this place again, and they will be trapped in this place forever.

There was no better way, Su Yichen could only use constant jumps to get closer to the target, hoping to arrive at the wormhole and leave as soon as possible. But the longer the time, the more jumps, the shorter the range of their movement, when the eleventh leap was completed, the distance traveled by the Pioneer spacecraft had been shortened to 91 astronomical units, seeing this distance display, Su Yichen was already speechless in his heart.

"Let's switch to normal regular sailing, target...... Wormholes. In this case, Su Yichen finally gave up the idea of using jump flight again, and ordered the spacecraft to sail towards the wormhole in an ordinary way. Because he knew very well in his heart that even if he made another jump, it would be useless, and if the preparation time for the jump and the energy consumed, including the proportion of space stretching were getting larger and larger, then it would be better to move forward in an ordinary way of sailing.

Next, they don't know how long they will stay here, maybe hundreds of years, maybe thousands of years or even ten thousand years, of course life as human beings can't be so long, by that time Su Yichen and his wife have already passed away, only Su Wei, who is an intelligent life, will always live, and then Su Wei will leave with their corpses, if the wormhole still exists, .......

Giving up the jump flight is equivalent to giving up the opportunity to escape from here, in fact, judging from the situation, it is impossible for them to escape from this airspace, but Su Yichen has always insisted. When he made the order to fly normally, his heart relaxed, and he smiled at Luo Yan guiltily: "Our luck is not good, it seems that you are going to stay here with me forever." ”

"What does it matter?" Luo Yan also replied with a smile, there was no complaint in her eyes, only a strong love, as long as the two were together, what difference did it make to her where they were? (To be continued.) )
