Ye Wenjie, watch my moves closely.

Chapter 31 I, Qin Shi Huang, need money.

Li Youyu's words instantly silenced Evans and Peterson.

It wasn't a silence born of unwillingness to speak, but rather a silence born of overwhelming emotion.

Evans glanced around warily, and only after confirming that no one was around did he cautiously begin, "Dr. Peterson, let me formally introduce you to this man. This is Qin Shi Huang, the one who told me the story of the Lord in the rural Northwest. Lee, this is Peterson. He is obsessed with the existence of the Lord and is willing to join our cause."

Evans's introduction dispelled the fog that had been hanging over them. Peterson no longer spoke cautiously and tentatively. He said, "How could Jupiter's radio bursts be related to the Sun? After that observation, we demonstrated that the mechanism of the radio bursts originated from the activity of the metallic hydrogen plates inside Jupiter."

Li Youyu did not answer for the time being, and led the two to the data room of the launch system.

All the classified materials here had been moved out of the Second Artillery Corps' inventory at Hong'an, and the room was originally empty. However, in order to welcome Evans, Li Youyu specially moved some of the documents containing the observation data from that year back.

By searching by year, Li Youyu easily found the radio burst data that Ye Wenjie had requested back then, as well as the time and waveform of the two solar interferences that affected Hong'an.

"Sixteen minutes and twenty-four seconds."

Li Youyu circled the time of the solar interference and the time of the observed Jupiter radio burst.

The time difference is 16 minutes and 24 seconds.

"16 minutes and 24 seconds," Evans asked, "What does that represent? What does it have to do with the sun you mentioned?"

Peterson's mind works faster.

He took out his notebook, drew three dots on a piece of white paper with a pencil, and then connected them with lines to form a triangle.

Each side of the triangle is a long string of strange numbers. Peterson divides these numbers by another ridiculously large constant, and then subtracts the results...

"16 minute and 24 second".

Peterson put down his pen with a trembling hand, let out a long sigh, and turned to Evans to explain: "These three points are the relative positions of the Earth, the Sun, and Jupiter. Divide their respective distances by the speed of light, uh, electromagnetic waves travel at the speed of light in a vacuum."

"I know that," Evans said. "Go on, I'll ask you if you don't understand."

Peterson circled the result of the division equation and said, "These numbers represent the time it takes for electromagnetic waves to travel to Earth. This is from Jupiter to Earth, this is from the Sun to Earth, and this is from Jupiter to the Sun and then to Earth."

Evans converted the largest result to minutes, which was exactly sixteen minutes and twenty-four seconds.

"But how can you be sure that the source of both solar interference events was a radio burst from Jupiter?" Peterson had just finished asking when he immediately exclaimed "Oh!" and bent down to rummage through a dusty file folder to find the waveforms of the two Jupiter radio bursts.

These dozens of pages of waveforms were copied from long strips of signal recording paper by him back then, and they still have the marks he made back then.

Just like Ye Wenjie did back then, Peterson arranged the photocopies neatly on the ground, and then placed the waveform of the interference at the Red Coast base next to it for careful comparison.

Evans also leaned over, and after a long while, he raised his head, his brows furrowed.

Even though he didn't understand the technology, he could tell that the two images did not overlap on the timeline.

"No, no," Peterson shook his head in denial. "Although the radiation waveforms of Jupiter and the Sun appear different on the surface, their trends over time are the same."

Due to technological and international constraints, there was not much to refer to in terms of electromagnetic observations on the Hongan side. Ye Wenjie did not see the similarity between the two at the time, so she abandoned the study of the solar model.

But Peterson was different; he had free access to data from all radio stations in Europe and the United States.

Having seen countless electromagnetic waveforms, Peterson was all too familiar with this situation; it was a manifestation of superimposed interference, perhaps a sine wave, perhaps a square wave.

Due to limitations in available technology, Peterson is currently unable to make a determination.

However, one result is clear: the interference radiation from the Sun and the electromagnetic radiation from Jupiter originate from the same source.

Having determined that Jupiter's radiation was the sole source, Peterson was able to formulate a bold hypothesis:

The sun did indeed reflect Jupiter's electromagnetic waves back to Earth, and the magnitude of the reflection was exponential.

But why is the sun able to reflect Jupiter's electromagnetic waves?

Peterson searched his mind for all the research he knew about the sun, but none of it supported this theoretical hypothesis.

He tried to verify this with Li Youyu, but Li Youyu didn't give a direct answer, only telling him...

"We can give it a try."

Ye Wenjie's research on solar energy mirrors has not been published, so only Ye Wenjie and Li Youyu currently know the principle of solar gain reflection.

Peterson and Evans followed Li Youyu to the launch control room at the Red Coast Base, where the area had already been cleared out.

All the launch parameters had been pre-entered into the old computer on the console.

All Li Youyu needed to do was point the antenna at the sun and press the launch button.

Click.

The sound of a relay engaging came from the control panel, and the large external radar hummed as it emitted electromagnetic waves for testing toward the sun.

Next, Li Youyu turned on an old military radio and tuned its receiving band to 12,000 hertz.

A low, rustling sound came from the radio's loudspeaker—the background radiation from the universe.

Evans asked curiously, "Why not use this big thing to receive electromagnetic waves? The electromagnetic waves coming from the sun should be very weak, right? Can this old radio even receive them?"

Peterson frowned and said, "If the sun really does have gain reflection, this radio station should receive some signals, though I'm not entirely sure."

After 16 minutes and 40 seconds of launch.

The monitoring headphones suddenly received a high-frequency electromagnetic wave. After being modulated and demodulated by the radio station, the electromagnetic wave was restored to an audio signal.

I am Qin Shi Huang.

The sound was so clear, it felt as if it were right next to my ear.

Evans and Peterson stared in shock at Li Youyu's retreating figure; the voice belonged to him!

This electromagnetic wave, which travels the distance between the Earth and the Sun, surprisingly doesn't have much distortion!

The sun's amplifying reflection effect is even stronger than expected!

So, if we increase the power and broadcast outwards, would we be able to contact extraterrestrial civilizations?

Project Ozma did something similar, but they simply pointed their antennas at outer space to emit electromagnetic waves. Electromagnetic waves of that power would probably have exhausted their energy before even leaving the Oort cloud.

so....

Peterson's arm gently touched Evans's.

After this verification, he was highly certain that the story of the Easterner was not fabricated, that the civilization called Trisolaris truly existed, and that it had already made contact with him.

Evans nodded slightly.

Peterson has completed his task, and now it's his turn to take the lead.

What he needs to do now is to find out the frequency and direction of the electromagnetic waves emitted by Li Youyu from the transmission system of this dilapidated radio astronomy base.

Connect with the Lord!
