Liu Weiping jumped out of the prospecting car, and he lay on the ground, whirring down the snow-covered hillside. Zhao Yonggang and Han Bingbin spent all their computing power speculating on what forces would dig up the wreckage of the Tunguska spacecraft before Noahbrisk, while Liu Weiping searched the snow for the copper record he had lost earlier.

No matter how advanced the technology of the Tunguska spacecraft is, it has an electron tube module on it, using the technology of the early twentieth century, obviously to broadcast some information to the outside, Liu Weiping accidentally intercepted the Markov equation last time, he realized that maybe there will be some information hidden in the copper record, this alien spacecraft seems to be broadcasting the signal with the help of human tube technology, and the information value on the copper record should be far greater than the superconducting alloy of the Tunguska spacecraft hull.

After a while, Liu Weiping slid to the mining truck that Noahbrisk was the first to transport, and the mining truck was covered tightly by the snow washed down from the mountain, but fortunately, the unmanned survey aircraft that were not damaged on the top of the mountain had flown over with Liu Weiping, and these unmanned survey machines circled around the location of the mining truck for a while and found a weak metal signal in the snowdrift twenty meters away from the grab of the prospecting vehicle.

Liu Weiping got the positioning of the metal signal and quickly stood up and prepared to run over, he just stood up, most of his body immediately fell into the snow and couldn't move, Liu Weiping had no choice but to climb down and slowly crawl over, under the guidance of the unmanned reconnaissance aircraft, Liu Weiping finally moved to the destination, he flew with both hands, quickly cut the snow on the ground, and after a while, he opened a big pit more than two meters deep, in the melting snow water, the copper record that had corroded into a dark green lay there quietly.

Liu Weiping was like a treasure, he picked up the copper record with both hands and shouted, "Found it!" Got it! Han Bingbin shouted to him in the wireless energy information network, "Professor, you are looking for death, such a loud voice, do you want to have another avalanche!" ”

After receiving Han Bingbin's reminder, Liu Weiping turned off the speaker in fright, grabbed the copper record with one hand, and hurriedly climbed out of the snow pit and climbed all the way to it.

He saw that the unmanned reconnaissance planes surrounding him suddenly dispersed in all directions, some over the top of Baikal Mountain, and some flew towards the east. Zhao Yonggang's signal came from the wireless energy information network, and he was still closely following the situation on the summit of Baikal, "Professor, we have to expand the scope of the search, we must find out who poached the alien spacecraft, I don't believe it, there will be no clues." ”

Liu Weiping lowered his head, glanced at the copper record in his hand, and said to Zhao Yonggang, "Yonggang, you have to do me a favor, help me build an algorithm on the host computer of Clifford Building, I want to restore the information on this copper record." He turned the copper record over, although the dark green copper record was corroded, but the etched lines of different thicknesses on it were still there, Liu Weiping sent the photos of both sides of the copper record to Zhao Yonggang.

Zhao Yonggang, who was hiding on the large quantum computer in the Clifford Building, was extremely powerful, and although he was anxious to find the superconducting alloy on the Tunguska spacecraft, he was as curious about the copper record that Liu Weiping found, and he quickly simulated a record player program, and entered Liu Weiping's photo into it, and the record player program made a strange noise.

"What is this signal? Could it be some kind of brainwave? Han Bingbin also shared the record program together, and he, like the other two, had no clue.

"It shouldn't be a human brainwave signal, otherwise we wouldn't be able to unravel it." Liu Weiping affirmed, "You see, there are still rules to follow. Zhao Yonggang has extended a waveform analyzer for the record player program, which restores the dense lines on the copper record into square waves.

"What is this base? If you use square waves, it should be a pulse signal with a fixed frequency, but these square waves are of different lengths and do not have a fixed frequency. Han Bingbin said puzzled.

On the top of the waveform analyzer, there are 56 consecutive square wave signals, and the time of these square wave signals is different and irregular.

"Okay, Professor, let's let it go for a while, I think we need to increase the number of unmanned reconnaissance aircraft in Siberia, and we must find clues to the Tunguska spacecraft." Although Zhao Yonggang has powerful computing power, he can't explain the meaning of these 56 square wave signals for a while.

"Why 56 and not some other number?" Liu Weiping did not give up, he chased after him.

"Professor, our computing power now has a cost, not as much as before, and I think it is the top priority to search for Siberia now." Han Bingbin echoed beside him.

Zhao Yonggang said, "But we should find a way to unlock the secrets in this copper record." Since the Professor is so sure that it is part of the Tunguska ship, if we unravel the information in it, it may lead us to the Tunguska ship. ”

"Makes sense." Han Bingbin said, "But how should we start working, these 56 square waves are too clueless." ”

"You don't have to worry." Zhao Yonggang said, "You hurry up and deploy unmanned reconnaissance aircraft to expand the search range, and I can find a huge pool of free computing power." ”

"Free hash pool?" This time it was Han Bingbin's turn and Liu Weiping to be surprised at the same time.

"Wu Kefen, she can use the Supercomputer of the Outram Observatory with more than 100 million CPUs, and maybe she can unlock the secrets on this copper record."

"That's great." Hearing Zhao Yonggang say this, Liu Weiping seemed to see hope, 100 million CPUs, how much computing power would be, but Zhao Yonggang immediately poured cold water on him, "But those processors are not quantum processors, they are the technology of the previous generation." ”

"That's also good, hurry up and send the upper wave of the copper record to Wu Kefen." Han Bingbin was anxious to end the task in front of him, he comforted Liu Weiping and said, "Although it is the technology of the previous generation, 100 million CPUs are more powerful than you and my host, let's hurry back to the western slope and dig out Yuri, he will come in handy." ”

Liu Weiping had no choice but to get on the airship with Han Bingbin again, and slowly flew towards the western slope of Baikal, through the porthole, he saw the airships of Noah Brisk Company everywhere, and countless miniature unmanned reconnaissance planes swarmed out from the cargo hold of the airship, scattered along Baikal, and drew virtual squares along the Great Siberian Plain, each trying to find any trace of digital civilization.

It was also a busy scene on the western slope, and Noahbrisk had already brought in several giant excavators, which had dug a tunnel tens of meters wide along the drilling site, and a tractor was dragging Yuri out of the tunnel.

At this time, Liu Weiping suddenly received a signal from Zhao Yonggang, "Professor, come on, Wu Kefen invites us to a video conference." While speaking, Liu Weiping and Han Bingbin have been dragged into the virtual conference room by Wu Kefen, and they saw Wu Kefen standing in the middle of the conference room, Liu Weiping and others sitting next to him, Wu Kefen's conference room has four walls open, the whole background is the vast universe, the stars are shining on the black background, and the Milky Way is when he looks up, Liu Weiping is very familiar with this, he was pleasantly surprised, and felt that Wu Kefen must have discovered something when he looked for them so quickly.
