The contact between the two sides took place in a relaxed state, and of course Dada was a little more excited than the calm Ike. As the topic unfolded, Dada's mood gradually calmed down and the narration became more organized.

"According to you, the planet Dhaka is 60 light-years away from here?" After listening to Dada's description of their home planet, Ike was very surprised, 60 light years, this distance is not far for Ike and them, the Pioneer spacecraft with jump technology only needs to start a jump, and then after a period of curvature and ordinary sailing to reach it. If the coordinates are correct and they have a complete map of their routes, it will definitely not take more than a month to reach the planet Dhaka.

However, unlike Dada, the technology level of the Dhaka people is only in the late stage of primitive civilization, and they have not yet entered the stage of cosmic civilization. In addition, Ike can be very sure that the Explorer spacecraft is just a primitive spacecraft with a controlled fusion engine, and such a spacecraft is extremely limited in its ability to travel in space, especially its speed, which cannot run so fast in terms of ordinary sailing acceleration.

Not only did Ike find it strange, but Su Yichen was also strange. When Su Yichen piloted the first Pioneer to Pluto, his spacecraft engine was a controlled fusion engine. Su Yichen is very familiar with the performance of the spacecraft of this engine, and the long distance of 60 light years cannot fly for hundreds of years without using the curvature engine.

"That's right." Dada nodded and said that there would be no mistake, how far away his home planet was, Dada knew very well in his heart, not to mention that he didn't need to lie about it.

"How much time have you spent since you started?" Ike frowned and thought about it, maybe Dada was sailing using hibernation technology, if they were using hibernation technology. Theoretically, then, the Explorer spacecraft would travel an infinite distance. In Ike's opinion, it was only possible to come here from 60 light-years away, with the capabilities of the Explorer spacecraft. In order to confirm his guess, Ike asked a special question.

"16 years and 97 days."

Unexpectedly, Dada gave a completely impossible answer. This surprised everyone, what! 16 years and 97 days? 60 light-years away? This is simply impossible for a spaceship that can only travel at normal speeds.

Su Yichen glanced at Dada in surprise and interjected, "May I ask how the time standard of Planet Dhaka is calculated?" That is, the time it takes for your home star to rotate and orbit the star. ”

The reason why Su Yichen asked this is reasonable, as mentioned earlier, the rotation and revolution of the home star where each civilization is located are not equal, some planets are faster, some planets are slower, if you add some other astronomical special environments, then their time and the time used by human beings are also different. Maybe. The rotation and revolution of the planet Dhaka is much slower than that of the Earth, so their annual cycle may be many years past compared to the Earth. Similarly, the life span of the people of Dhaka will be much longer when compared to the time of the earth, so that the time standard of 16 years and 97 days that Dada refers to is different.

Dada was stunned for a moment, and then laughed, just when everyone was a little puzzled. Dada stated the cycle of their planet's rotation and revolution to make sure there was no misunderstanding. Dada also made a point of mentioning the mass and circumference of the planet Dhaka, according to the information Dada said, although the time difference between the planet Dhaka and the earth is longer, but the difference between the two sides is not too much.

This result completely overturned the speculation in Su Yichen's heart, and just when everyone was puzzled, Dada told them. The reason why the Explorer spacecraft reached an area 60 light-years away in 16 years and 97 days is because they have a special method.

"Special means?" This immediately aroused everyone's curiosity, what kind of special means can actually make a spacecraft with a controlled fusion engine fly an ultra-long distance of 60 light years in a short period of 16 years and 97 days? Do the people of Dhaka still have secret technology that they don't know? This thought flashed in Ike's mind and was denied by him, knowing that the Brain of the Pioneer spacecraft had taken over the other party's spaceship, and all the equipment of the other spaceship was under the control of the Brain. Although the brain has temporarily let go of these controls, it can still easily take back control anytime and anywhere. The technological level of the Rand civilization is simply incomparable to that of the Dhaka people, and even Su Yichen's spaceship cannot resist such control, let alone Dada's them?

If there was any special device, the brain would have found out a long time ago, but the problem is that the brain did not find that such a device existed. So, this is Dada lying? Ike squinted at Dada, but he didn't realize that the other party could lie, not to mention that this kind of lie was easy to debunk, and Dada didn't need it.

"One of my crew members, a special crew member, to be exact." Dada said with a smile, and at the same time his expression was smug, and he was surprised that he could make the members of an alien civilization much taller than the Dhakans, which made Dada very proud.

In the Explorer spacecraft, Dada's crew had calmed down after the initial panic, and the sudden disappearance of Captain Dada in full view of everyone shocked the crew, and at the same time, a terrible thought flashed through most people's minds, and some people even almost made irrational actions in panic, but fortunately, there were calm people who stopped it in time.

When Dada's image was shown on the screen, telling everyone that he had not been harmed, and that he had come to the Pioneer spacecraft to get up close and personal with the people of the alien civilization, his condition was good, better than ever, and before he returned to the Explorer, I hope that the crew will do their jobs and wait patiently for his return.

Dada's image appearance and these words were like a reassuring pill to reassure the panicked crew, since the captain was okay and the alien civilization did not make any moves to harm them, then the other party was still very friendly. When Dada was in contact with Ike and others in the Pioneer spacecraft, the crew of the Explorer returned to their respective posts, although everyone performed their duties according to Dada's requirements, but for the appearance of alien civilizations and the incredible scene just now, many people still have great curiosity in their hearts.

"Saipu. You just said it was a spatial fluctuation? A crew member turned his head to Saipu uncontrollably and asked, Saipu is one of the members of the Explorer spacecraft, and also a physicist who is also one of the three scientists on board the ship that Dada once mentioned, when Dada disappeared out of thin air under everyone's noses, causing everyone to panic, it was Saipu who stood up and advised everyone to calm down.

"I'm sure!" Saipu nodded.

"Spatial fluctuations...... Could it be that this alien civilization already has the ability to transfer space? That's what made the captain move from our ship to the other party's ship in an instant? The questioner thought for a moment and asked.

Saipu shook his head. He pondered and said: "There is no pure spatial transfer, from the spatial fluctuations just generated, I feel that this is a change in dimension, I think everyone has a certain understanding of the meaning of dimension, our space-time is a normal four-dimensional, that is, three-dimensional space plus time dimension constitutes the universe in which we are located." But in fact, there are higher dimensions in the universe, and the higher dimensions are compatible with the lower dimensions, and the lower dimensional spaces can be freely shuttled and transformed in the high-dimensional space. If I'm not mistaken. The other party's civilization is extremely developed, and they already have a very complete high-dimensional technology, which can make the captain disappear from us in an instant, and then go to the opponent's spaceship. ”

"It's incredible!" The crew member who asked him was dumbfounded, although he was not a scientist, he was also a professional astronaut, and he had more professional knowledge than ordinary Dhaka people in terms of academic qualifications. He still knew a thing or two about the basic concept of dimension, and when Sai Pu told him that the biggest possibility was that the other party had high-dimensional abilities. This made the crew unimaginable.

And not only him, but the rest of the crew. Including the other two scientists were also extremely shocked, among the five of them, Sai Pu, who is a physicist, is the most professional person in this regard, not to mention that there is a special reason that makes everyone unconditionally believe in Sai Pu's judgment.

"High-dimensional ability, this ability is very terrifying, with perfect high-dimensional ability, you can almost freely travel through the universe." Another scientist muttered to himself. The Dhaka civilization's study of dimensions is much weaker than that of the earth civilization in Su Yichen's period, that is, the earth civilization that has entered the second-level cosmic civilization, and compared with the level of science and technology, the Dhaka civilization is only at the scientific and technological level of the earth at the beginning of the 21st century, and the study of dimensions is just the beginning of the theory. And in many respects it has not yet reached the perfection of the theory.

But even so, as a scientist, I still know something about dimensional theory and high-dimensional abilities, and it is extremely terrifying to have high-dimensional abilities, and when it reaches a certain level, it is not a problem to travel freely through the universe, even time and space. They never imagined that an alien civilization that they accidentally encountered in the universe would be such a powerful civilization, which was simply incredible.

Of course, due to the technological limitations of the Dhaka, their understanding of the capabilities of Ike and the Pioneer spaceship, or the technological level of the Rand civilization, is only a preliminary mastery of high-dimensional technology, if the Rand civilization has completely mastered the secrets of the dimension, then Ike will not drive the Pioneer spacecraft to the Andromeda galaxy from such a long distance.

Saipu put forward a hypothesis, and the members of the Explorer spacecraft did not reject his hypothesis, and even discussed it with each other based on his hypothesis and judgment. No matter how high the other party's civilization is and how powerful the technology is, at least one thing is for them to be reassured temporarily, that is, Ike and the others treat them as Dhaka's people with a relatively kind attitude, whether it is from the initial contact or now Dada comes to the other party's spaceship for face-to-face communication, the other party has shown a certain amount of goodwill.

Around the high-dimensional technology, several astronauts who don't know much about dimensions couldn't help but ask Sai Pu for advice, for their companions' inquiries, of course, Sai Pu explained one by one, not to mention that although they are now in their duties, in the absence of the captain, in fact, there is no work to be done on the spacecraft, all they can do is wait.

With the knowledge he knew, he explained the theory of dimensions in detail for the crew, and after listening to Sai Pu's explanation, everyone also understood a lot, but one of the crew members couldn't help but ask Sai Pu: "You say, when can our civilization reach such heights?" ”

"I don't know."

"Don't know?"

Sai Pu nodded with a wry smile: "It can't be calculated, the dimension is a very mysterious area, our civilization's research on this aspect is only on a theoretical basis, and it can only be applied when the theoretical foundation is perfect, but you must know that above the four dimensions, there are not only five dimensions, but also sixth, seventh, eighth, and even higher dimensions." And with each ascending dimension, the difficulty increases almost a hundredfold, and I am a scientist, and I can't determine this time with my imagination, so I can only answer that I don't know. ”

"Yes, Saipu is right, it's a long research process, maybe hundreds of years, maybe thousands, or even longer. According to the current theory, when the technology develops beyond the fifth dimension, that is, to the extent of reaching the sixth dimension, the scientific and technological ability has become so powerful that it is as omnipotent as the legendary immortals, perhaps, the alien civilization we have encountered is such a powerful civilization, which is the luck of our Dhaka people, and it is also the direction of our future goals. Another scientist agreed, and at the same time sighed a few words.

His emotion also touched on what Saipu thought in his heart, but he didn't say it. When it was guessed that Ike was using his high-dimensional ability to transfer Dada to the other party's spaceship, Sai Pu was both shocked and excited, shocked by the strength of the other party's civilization technology, and excited by the same strength of the other party's civilization technology. If such a powerful alien civilization can be helped, then the technological leap of the Dhaka people and the Dhaka civilization is conceivable, perhaps, this is a very rare opportunity for them, including the entire Dhaka civilization.

At this time, the screen that had calmed down suddenly lit up again, and Dada's image appeared in front of everyone, just when everyone thought that Dada's communication with the other party had ended and was about to return, who wanted Dada to say a word as soon as he opened his mouth, this sentence made everyone stunned, especially Sai Pu was stunned.
