"Who is that person?" Gongsun Shuren was already in a conversation with the pilgrim. Hearing Song Ziyu's words, he couldn't help but ask.
"That man is the guest from Venus——Nikola Tesla." Song Ziyu said this magical name.
"What did he do?" Gongsun Congyun asked.
"In a way, he established the principles of modern physics."
Song Ziyu talked eloquently, slowly recounting the past events between Tesla and Edison in the "Battle of AC and DC".
In the end, Tesla knocked Edison off the altar and ended the history of DC as the main body of electricity.
So, the problem comes back to its roots.
"What is alternating current?"
Gongsun Shuren said: "From the story you told me, alternating current is the mainstream of electricity use, but what needs to be done? How to make technological changes?"
Song Ziyu gritted his teeth and said, "Mr. Gongsun, let's make a deal? If I hand over the complete technology of alternating current to your hands, can I get your protection for me in exchange?"
"What on earth is going on?" Gongsun Shuren looked at his son.
Gongsun Congyun didn't dare to hide it, so he quickly told his father about the matter.
"Kill Kong Youfang? I don't know how you can cause such a big trouble!" Gongsun Shuren showed a pensive expression.
After a long time, Gongsun Shuren said: "This deal can be done! As long as you come up with the AC technology, our Gongsun family promises to provide you with protection."
"It's a deal!" Song Ziyu was overjoyed and immediately said: "I will give you what you want in two days at most. I hope you won't break my promise then."
"Breaking a promise? How could it be! Do I look like someone who breaks a promise?" Gongsun Shuren said.
"That's good!" Song Ziyu said.
…
After having dinner at Gongsun's house, Song Ziyu returned to his residence without stopping. After settling in, Song Ziyu traveled back to the civilized world.
Without stopping, Song Ziyu went straight to the Xinhua Library and started shopping frantically in front of books on electricity.
"Principles of Alternating Current", "Primary Application of Alternating Current", "Maintenance and Manufacturing of AC Motors", "Precautions for Erection of AC Power Grid"...
Song Ziyu purchased a series of books related to alternating current!
This behavior attracted the attention of an old man beside him who was looking up information.
"What are you doing, young man?" the old man asked.
The old man wears thick glasses and is quite old.
Song Ziyu heard this and said: "I plan to build an AC power plant."
The old man smiled and said: "Young man, are you a layman? It is impossible for you to build a qualified power plant with these basic books."
"Oh?" Song Ziyu asked curiously: "Then what else do I need?"
The old man said: "The easiest way is to have a complete set of power station drawings."
"Where can I get those things?" Song Ziyu asked.
"I have it!" the old man said mysteriously.
"Who are you?" Song Ziyu asked curiously.
The old man said: "No, I am a retired engineer from Nandu Thermal Power Plant."
"Nandu Thermal Power Plant?" Song Ziyu was stunned, because this thermal power plant had been demolished many years ago, and the land was used for commercial real estate.
"The thermal power plant is too polluting. Big cities like Nandu do not allow its existence, so it has become history... But the drawings of the thermal power plant are still there. If you are interested, I can sell them to you at a low price." The old man said.
"Old man, are you short of money?" Song Ziyu asked.
The old man sighed and said: "After the thermal power plant was abandoned, my wife and I were laid off. At that time, we didn't think it was a big deal, but now that we are getting older, we have to spend money for medical treatment and money to extend our lives. It’s my fifth year, and I’m still a bachelor, just because I don’t have money to give a bride price..."
The old man recounted with runny nose and tears.
Hearing the old man's words, Song Ziyu felt sad, so he said, "I bought the drawings and I want them now."
…
With enough books to buy and the thermal power station engineering drawings transferred to him by the old engineer, Song Ziyu traveled back to the wasteland overnight.
After a night's rest in the hotel, Song Ziyu went directly to visit Gongsun Shuren and Gongsun Congyun the next day.
Gongsun Congyun was receiving guests, but when he heard that Song Ziyu was coming, he took the guests directly to the study.
Gongsun Congyun really wanted to see how much surprise Song Ziyu could bring.
When they saw the books and drawings brought by Song Ziyu, both the Gongsun family and the strange guest showed surprised expressions.
"Are these all?" Gongsun Shuren also didn't believe his eyes.
Books...
In this wasteland, books are such precious things.
Civilization has ended, and books are the only link between the previous era and this era.
When Song Ziyu placed the book in front of Gongsun Shuren, the shock it brought can be described as terrifying!
"These are books on the application of alternating current. I believe that with your attainments in electricity and electromagnetism, it is no problem to master this knowledge." Song Ziyu said to Gongsun Shuren.
Gongsun Shuren's scalp was numb from the shock, and he could not recover for a long time.
Song Ziyu didn't care about this and opened the thick cowhide document bag again.
Huge engineering drawings were presented in front of Gongsun Shuren!
The old man's eyes completely lost focus!
"This is a drawing of a thermal power station built using AC motors, as well as the accompanying AC power grid wiring... Everything is on the drawing, with detailed explanations of the building proportions and symbols... If you use this thing to follow the pattern, you can build the same AC electric power plant. Power plant!" Song Ziyu said.
Love reading books
Gongsun Shuren put on his reading glasses and pounced on the drawing and began to study it inch by inch.
"How can it be so concise?" Gongsun Shuren couldn't help but exclaimed.
"How is it possible to construct a transmission grid like this?" Gongsun Shuren shouted.
At this time, Gongsun Congyun was no longer calm, and he left his guests behind and began to study carefully.
really!
Gongsun Congyun turned out to be a technical leader.
Song Ziyu was slightly surprised, no wonder Tianshui Town stood out in the wasteland.
They have the skills!
…
It took a long time for Gongsun and his son to crawl out of the drawing.
The father and son exchanged glances. Gongsun Congyun nodded, and then said to the guest: "President Xu, my family has important matters today. We will discuss your issues in detail tomorrow, okay?"
The guest named President Xu was a middle-aged man wearing a gray robe. He seemed to have no presence there. It was not until Gongsun Congyun greeted him that Song Ziyu realized that there were other guests in the room.
"Okay, I'll give you time to consider my proposal, and I'll come back to you tomorrow!" The middle-aged man said to Gongsun Congyun without being humble or arrogant.
Then the middle-aged man looked at Gongsun Shuren and said, "Old Ren, I, the junior, will take your leave first."
"Well, walk slowly." Gongsun Shuren didn't seem interested in the middle-aged man and didn't even raise his head.
The middle-aged man glanced at Song Ziyu curiously, without saying hello, and then walked out of the room.
This person looks familiar. Have you seen him somewhere?
Song Ziyu wondered.
However, Song Ziyu did not have the energy to delve into these issues.
Song Ziyu looked at the Gongsun family and his son.
"How is it? Are you satisfied with the things?" Song Ziyu asked.
