Back in the lab, Xia Fei takes out two snakeeye berries from the space ring and hands them to Harris. He also eats two of them. For those who work for a long time, the meal is just to meet the needs of the stomach. The real energy intake and the inspiration depend on these magical fruits.

"Now that we know that the second frequency is connected to some mysterious master control system in the universe, it's time to find out the truth." Xia Fei said.

Harris excitedly said: "according to my analysis, there are only two possibilities. One is that the manufacturer of the nether bell deliberately adds a second frequency to master the user's dynamic. This kind of speculation is not likely, because once the user finds out that the manufacturer is secretly monitoring himself, he will be furious."

"There is also the reason why the bell of the nether world can accurately find the other communicators that it needs to connect, and transmit the signal in the form of directional meson energy waves. It must be located precisely."

"It's so difficult to locate a small communicator in the vast starry sea, so I guess that the alien civilization that produced this kind of thing must have built a super large deep space induction array in an unknown corner of the Starry Sea, which is used to find the communicators scattered all over the star sea and help them locate each other in the form of central rotation."

Xia Fei nodded, opened the video system, and showed the inner structure of the bell of the nether world in the form of a thousand times enlarged.

"What you said is very reasonable. If the super large induction array is really built in the vast sea of stars, the technology level involved must be very high. What I don't understand is that if the induction array really exists, why don't aliens use it directly to transmit signals, but just use it as a navigation system?" Xia Fei holds his arms in his arms and touches his chin.

Harris thought for a moment and said, "in fact, this is not difficult to understand. If all signals are transferred by induction array, there will be suspicion of privacy being peeped at. The designer of the nether bell may have considered this, so he separated the communication and positioning systems."

Xia Fei sighed: "if possible, I really want to see this super induction array. What kind of technology does he use to scan the whole Xinghai? You should know that it has to go through layers of barriers. Moreover, the array has been working for so many years without any damage. Is there anyone else maintaining it?"

Xia Fei shook his head when he thought of this. The bell of the nether world was found in the ruins by the ancestors of yingsha sect. At that time, the alien civilization had already been destroyed. Where would there be any number of people to maintain the induction array in tens of thousands of years.

Xia Fei suddenly thought of the three words robot. If it is said that robots are responsible for maintenance work, it is completely possible. As long as there is light, they will have energy. As long as there is energy, they can repair themselves. Is this giant induction array hidden in the universe is maintained by robot man?

Perhaps because of Qin Mang's influence, Xia Fei is very sensitive to the three words "robot". He has always wanted to see with his own eyes what intelligent robots look like and how they work. Unfortunately, he fails to do so.

"If we follow this mysterious wave, can we locate the super scanning array?" Xia Fei asked.

Harris said with a smile: "scanning array is just a guess, if you really follow the track of the radio wave, what will be found, no one can know."

Xia Fei said: "of course I know that. I only care about whether there is a way to find the signal source, whatever it is."

"It's hard to locate a node in the universe because there are so many variables to consider, but if we can build a frequency decay index analyzer, it's possible to find it," Harris said

However, any frequency signal will be attenuated in the universe. With the further the propagation distance is, the weaker the signal will be, and finally disappear in the black space. Tracking the target according to the strength of the signal source is a general tracking method, but it needs to simulate a decoding system to imitate the signal source.

"In this case, our next step is not only to clarify the directional transmission technology of the nether bell, but also to try to develop an analog decoding system for tracking signal sources." Xia Fei said in a deep voice.

Harris nodded. There was no other way for him to obey Xiafei's request, while the ghost said, "you don't want to find the induction array that doesn't exist, do you?"? Harris has said that it's just a guess. It's really going to find something that no one can predict. "

Xia Fei said with a smile: "if we can have a scanning array that can sense the whole Xinghai, or if we master this technology, who can compete with quantum companies in the field of communication?"

"Besides, I have a hunch that there may be some connection between the induction array and the super radar used by Titan class warships. However, Titan's radar system lies in ultra long distance transmission, while the nether bell system has its own unique features in positioning. If the two are combined, it will be a new product across the times."

……

As time goes on, the bell of the nether world is divided into packages and unwrapped one by one. The new discovery is naturally gratifying. How to combine the point-to-point transmission technology of the nether bell with the radar system of the Titan class warship is still a headache.Xia Fei didn't expect that the nether bell used a completely different technology from that of ordinary radar. Technically speaking, the two technologies are not universal, which is difficult to learn from.

After learning about the communication mode of the nether bell, Harris' work came to an end. He began to devote more to the cultivation of his new students and the research of single cell biology.

I don't know why Harris recently became so interested in simple cell biology that he kept looking at high-resolution microscopes every day and recording the process of cell growth.

Xia Fei knows that it is impossible for Harris to give up the research on the seventh brain region. He must have thought of some ideas, so he will turn to study those small things. Xia Fei doesn't mind. His crazy spirit has been reduced a lot recently. He often deliberately helps others. He wants to come to the laboratory to find some of his past. In addition, he is getting older and older, mentally And no longer as stubborn as it used to be.

The launch of the new radar is still not in sight, but the time of the game strategy formulated by him is getting closer and closer. Boten has already set out to participate in the strongest warship competition of the Ministry of military affairs. In another two months, it will be the key event of Xiafei, the golden finger cup.

Xia Fei knows that Avril is still waiting for himself in the capital star circle, so he packed up his bags and set foot on the journey to the capital star circle again. His research has entered a bottleneck. Maybe he can come up with any good ideas by changing his mood.

Avril knew that Xia Fei was leaving, so she was so excited that she locked herself in her room and planned every day's journey. She didn't want to waste every second of her time together. (to be continued, please visit www.qidian.com , more chapters, support authors, support legitimate reading! )
