The contact between the two parties was carried out in a relaxed state. Of course, compared with the calm Eke, Dada seemed to be more excited. As the topic unfolded, Dada's mood gradually calmed down and the narrative was more organized.

"According to your words, the planet Dhaka is 60 light years away from this place?" After listening to Dada's description of their parent star, Ike was very strange. 60 light years, this distance is not far for Ike and the others. The Pioneer Space Exploration Spaceship with transition technology only needs to start a jump, and then after a period of curvature and ordinary navigation, it can be reached. If the coordinate position is accurate and they have a complete navigation star map, then the time to arrive at the planet Dhaka will never exceed one month.

However, Dada and the others are different. The Dhaka people's technological level is only in the late stage of primitive civilization, and they have not yet entered the stage of cosmic civilization. In addition, Ike is very sure that the Explorer spacecraft is just a primitive spacecraft with a controllable fusion engine. Such a spacecraft is greatly restricted in the universe, especially its speed, calculated by ordinary navigation acceleration, it is impossible for it to run so fast.

Not only Ike found it strange, but Su Yichen was also strange. When Su Yichen drove the first Pioneer to Pluto, his spacecraft engine was a controllable fusion engine. Su Yichen had an unusual understanding of the performance of this type of engine. The long distance of 60 light-years, without using a curvature engine, could not fly for hundreds of years.

"That's right." Dada nodded and said that there was no mistake. Dada knew very well how far his mother star was, and he didn't have to lie at this point.

"How much time has it taken for you to start now?" Ike frowned and thought. Maybe Dada and the others were sailing with dormant technology. If they use dormant technology, theoretically speaking, the navigation distance of the Explorer spacecraft will be extended without limit. In Ike's view, there is only this possibility to come here from 60 light years away to the Explorer spacecraft's ability. In order to determine his guess, Ike asked.

"16 years and 97 days."

Unexpectedly, Dada gave an entirely impossible answer, which surprised everyone, what! 16 years and 97 days? 60 light-year distance? This is simply impossible for a spacecraft that can only sail at ordinary speeds.

Su Yichen looked at Dada in surprise and asked, "How is the time standard of the Dhaka planet calculated? That is, the rotation of your parent planet and the time it takes to orbit around the star."

Su Yichen asked this reason. As mentioned earlier, the rotation and revolution of the parent planet where each civilization is located is not equal. Some planets are faster and some planets are slower. If other special astronomical environments are added, their time is different from the time used by humans. Perhaps, the rotation and revolution of the planet Dhaka is much slower than that of the earth, so their one-year cycle may have passed many years compared to the earth. Similarly, compared with the time of the earth, the lifespan of the Dhaka people will be much longer. In this way, the time standard of 16 years and 97 days referred to by Dada is different.

Dada was stunned at first, then laughed. Just as everyone was confused, Dada mentioned the cycle of their planet's rotation and revolution. In order to ensure that there was no misunderstanding, Dada also specifically mentioned the data on the mass and perimeter of the planet. According to the information Dada said, although the time difference between the planet's Dhaka is longer than that of the earth, the difference between the two sides is not too many.

This result completely overturned Su Yichen's guess. Just when everyone was puzzled, Dada told them that the reason why the Explorer spacecraft arrived in an area 60 light years away in 16 years and 97 days was because they had a relatively special method.

"Special means?" This immediately aroused everyone's curiosity. What kind of special means can actually make a spacecraft with a controllable fusion engine fly out of a very long distance of 60 light years in a short period of 16 years and 97 days? Do the Dhaka people have secret technologies they don't know? This idea flashed slightly in Ike's mind and was denied by him. You must know that the intelligent brain of the Pioneer Space Exploration Space has taken over the other's spacecraft, and all the equipment of the other spacecraft are under the control of the intelligent brain. Although the intelligent brain has temporarily released these controls, it can still easily get back control anytime and anywhere. The technological level of the Rand civilization is incomparable to the Dhaka people. Even Su Yichen's spacecraft cannot resist such control, let alone Dada and others?

If there were any special devices, the Intelligent Brain would have found it long ago. The problem is that the Intelligent Brain did not find such devices. Then, is Dada lying? Ike narrowed his eyes and looked at Dada. But he did not find that the other party was lying, not to mention that this kind of lie is easy to expose, and Dada has no need for this.

"To be precise, it's one of my crew members, a special crew member." Dada said with a smile, and his expression was filled with pride. Dada was very proud of the members of the alien civilization who could make it much taller than the Dhaka people.

In the Explorer spacecraft, Dada's crew had calmed down after experiencing the initial panic. Captain Dada suddenly disappeared in full view of everyone, which shocked the crew. At the same time, a terrible thought flashed through most people's minds, and some even almost made irrational actions in fear. Fortunately, there were calm people who stopped it in time.

When Dada's image was displayed on the screen, telling everyone that he had not been hurt, and that he had come to the Pioneer Space exploration spacecraft to get close to people from alien civilizations. His situation was very good, unprecedented. Before he returned to Explorer, he hoped that the crew would each hold their own positions and wait patiently for his return.

The appearance of Dada's image and these words were like a reassurance that made the panicked crew members relieved. Since the captain was fine and the alien civilization did not make any move to hurt them, it means that the other party was still very friendly. When Dada was in contact with Ike and others, the crew members of the Explorer returned to their respective positions. Although everyone was in charge of the post according to Dada's requirements, many people were still extremely curious about the emergence of alien civilization and the incredible scene just now.

"Saipu, did you just say that was a space fluctuation?" A crew member couldn't help but turn his head to ask Saipu. Saipu was one of the members of the Explorer spacecraft and also one of the physicists Dada once mentioned. When Dada disappeared out of thin air under everyone's noses, it was Saipu who stood up to advise everyone to calm down.

"I'm sure!" Saipu nodded.

"Space fluctuations... Could it be that this alien civilization already has the ability to transfer space? This allowed the captain to transfer from our spaceship to the other party's spaceship in an instant?" The person who asked thought for a while and asked.

Saipu shook his head and said, "Pure space transfer does not exist, from the space fluctuations just now. I feel that this is a change of dimensions. I think everyone has a certain understanding of the meaning of dimensions. Our time and space are normal four-dimensional, that is, three-dimensional space plus time dimensions form our universe. But in fact, there are higher dimensions in the universe. High dimensions are compatible with low dimensions, and low-dimensional space can be freely shuttled and transformed in high-dimensional space. If I guess correctly, the other party's civilization is extremely developed. They already have very complete high-dimensional technology, which allows the captain to disappear from us in an instant and then go to the other party's spacecraft."

"It's incredible!" The crew member who asked was stunned. Although he was not a scientist, he was also a professional astronaut. In terms of education, he had more professional knowledge than ordinary Dhaka people. He knew the basic concept of dimensions. When Saipu told him that the biggest possibility was that the other party had high-dimensional abilities. This made the crew member unimaginable.

Not only him, but the other crew members, including the other two scientists, were also extremely shocked. Among the five of them, Saipu, as physicists, is the most professional in this regard, and there is another special reason that makes everyone unconditionally believe Saipu's judgment.

"High-dimensional ability, this ability is very terrible. With perfect high-dimensional ability, you can almost freely travel through the universe." Another scientist murmured to himself that the Dhaka civilization's research on dimensions is much weaker than the Earth civilization in the Su Yichen period, that is, the Earth civilization that has entered the second-level cosmic civilization. From the perspective of scientific and technological level, the Dhaka civilization is only at the technological level of the earth at the beginning of the 21st century. Dimensional research is just the beginning of theory, and has not yet achieved theoretical improvement in many aspects.

But even so. As scientists, they still know some about dimension theory and high-dimensional abilities. Having high-dimensional abilities is extremely terrifying. When they reach a certain level, they can freely travel through the universe. Even time and space are no problem. They never thought that an alien civilization that unexpectedly encountered in the universe was such a powerful civilization, which was simply incredible.

Of course, due to the technological limitations of the Dhaka people, they did not have a perfect understanding of the capabilities of Ike and the Pioneer spacecraft, or the scientific level of the Rand civilization. The Rand civilization is now just a preliminary master of high-dimensional technology. If the Rand civilization has completely mastered the secret of dimensions, then Ike would not have driven the Pioneer space exploration spacecraft to the Andromeda system through such a long distance.

Saipu proposed the assumption, and the members of the Explorer spacecraft did not deny his assumptions, and even discussed them based on his assumptions and judgments. No matter how high the other party’s civilization is or how powerful the technology is, at least one thing is to reassure them for the time being, that is, Ike and others have a relatively kind attitude towards them, such as Dhaka people. Whether from the initial contact or the current Dada came to the other party’s spacecraft for face-to-face communication, the other party showed a certain kindness.

Focusing on high-dimensional technology, several astronauts who didn't know much about dimensions couldn't help asking Saipu for advice. Saipu of course explained to his companions one by one. Moreover, although they are now on duty, when the captain is not there, there is actually no work to do on the spacecraft. All they can do is wait.

Using the knowledge I know, I explained the theory of dimensions to the crew in detail. After listening to Saipu’s explanation, everyone also understood a lot, but a crew member couldn’t help but ask Saipu: “You said, when can our civilization reach such a height?”

"have no idea."

"have no idea?"

Saipu nodded with a wry smile: "It is impossible to calculate. Dimensions are a very mysterious area. Our civilization's research on this aspect is only based on the theoretical basis. It can only be applied after the theoretical foundation is improved. But you must know that there are not only five dimensions above the four dimensions, but also six dimensions, seven dimensions, eight dimensions and even higher dimensions. And every time one dimension rises, the difficulty increases almost a hundred times. I am a scientist, and I cannot use imagination to determine this time, so I can only answer that I don't know."

"Yes, Saipu is right. This is a very long research process, which may take hundreds of years, thousands of years, or even longer. According to current theory, when technology develops beyond the five dimensions, that is, to reach the sixth dimension, the technological ability has become as powerful as the legendary gods. Perhaps, the alien civilization we meet is such a powerful civilization. This is the luck of our Dhaka people and the direction of our future goals." Another scientist agreed on the side and sighed a few words.

His feelings also pointed out what Sai Pu thought in his heart, but did not say it. When he guessed that Ike used his high-dimensional ability to transfer Dada to the other party's spacecraft, Sai Pu was shocked and excited. What was shocked was the power of the other party's civilization technology, and what was excited was the power of the other party's civilization technology. If such a powerful alien civilization could be helped, then the technological overflow of the Dhaka people and the Dhaka civilization could be imagined. Perhaps, this was a very rare opportunity for them, including the entire Dhaka civilization.
