Ye Wenjie, watch my moves closely.

The day after my trip to Tsinghua University ended was the weekend.

Early in the morning, Ye Wenjie arrived at the radio astronomy observatory located at Miyun Mountain Reservoir.

This radio astronomy observatory, which was originally built in 66, was not as large as Hong'an in its initial scale, but with the financial support from Li Youyu over the past few years, it is now capable of transmitting electromagnetic waves for extended periods of time at high power.

Ye Wenjie stood before the control panel in the central control room, feeling as if she had been transported to another world. The last time she had conducted an electromagnetic wave transmission was more than four years ago, but these two instances felt like completely different worlds to her.

Four years ago, the launch room at the Red Coast Base was a small cement building filled with a dense array of control consoles. The numerous knobs and switches on the console were very resistant to operation, and some buttons had to be pressed at a specific angle to function properly.

During a launch operation, Ye Wenjie often has to move her body and coordinate her movements up and down.

Even in the cold winter, I often work up a sweat.

But the situation here is completely different.

The large room contained only a curved control panel with three screens, a keyboard, and two simple fire/stop buttons.

The old-fashioned instrument dials used to monitor launch status at the Red Coast have all been replaced with real-time screen displays here.

Everything was filled with a futuristic, technological feel.

Ye Wenjie couldn't help but wonder, were these really products of the same era?

"Don't stand there in a daze, Commander,"

Just as he was thinking, Zhang Zhi'ao walked in from outside with a group of people.

"It's not time to launch yet, let's come up with a plan first."

"Commander-in-Chief... what is that title?"

"Our organization needs a core figure, and naturally it's you. Don't look at me like that. The title of commander-in-chief was given by Li Youyu. You'll have to ask him."

That's not what I meant.

Ye Wenjie quite liked the title; it sounded like an epic poem from ancient Roman opera.

This time, the Future Historians had a new face: around forty years old, wearing a plaid short-sleeved shirt, with a buzz cut, black-rimmed glasses, a round face, and an honest appearance.

Zhang Zhi'ao pulled him in front of Ye Wenjie and introduced them, "Commander, this is Liu Chuan."

"Ah, hello, Mr. Liu Chuan."

"Hello, hello, Ms. Wenjie."

Liu Chuan smiled broadly.

Ye Wenjie noticed that Liu Chuan's dark skin seemed different from the general impression of scholars, so she asked, "What do you do for a living?"

Before Liu Chuan could speak, Zhang Zhi'ao interjected, "Electrician."

Liu Chuan's face darkened instantly, his benevolent smile freezing on his lips. "What electrician? It's Engineer Liu! A senior engineer!"

"Engineer Liu, Engineer Liu."

For some reason, Zhang Zhi'ao, the squadron leader of the North Sea Fleet, was somewhat intimidated when facing Liu's ship, and dared not even utter a loud word.

Faced with Liu Chuan's rebuttal, he could only nod repeatedly, hastily trying to make amends.

"Although Engineer Liu works at the power plant, he engages in literary creation in his spare time and has won several international awards. In the past, when we were doing simulations, we would often ask him to help write scripts for various factions. Professor Ye, you may not know this, but accurate and vivid written descriptions can help everyone quickly pinpoint the problem... um..."

"Is what you call helping?"

Liu Chuan glanced at Zhang Zhi'ao.

"Uh...free...get something for free?"

"Um."

Liu Chuan exhaled through his nose.

In short!

Zhang Zhi'ao said, "After careful consideration, we contacted Mr. Liu Chuan and successfully invited him to join the Future History School. For this launch plan, I think no one is more suitable than Engineer Liu."

"Alright, enough talk, let's get started. I have a lot I want to show the Trisolarans."

Liu Chuan sat down casually, habitually crossing his legs, took a cigarette from his pocket, smacked it a couple of times, and suddenly looked at Ye Wenjie, saying, "Commander, may I smoke?"

Ye Wenjie said, "Comrade Liu Chuan, please make yourself at home."

"Don't call me 'comrade,' it sounds too formal. Like Xiao Zhang, call me Engineer Liu... Hmm, I'd better not smoke, there's a woman here."

Everyone formed a circle and took their seats in turn, and the members of the Future Historians shared their views.

"I propose that the first batch of transmitted philosophical content, Nietzsche, Jacobi... instill nihilistic ideas in the Trisolarans, so that some of them will feel that survival is a meaningless thing."

"I think we need to give them prose and literature, so that they can empathize with the beauty of Earth and strengthen the alien forces within the Trisolarans that are protecting Earth."

"I suggest sending out musical melodies to showcase the cultural treasures of the Earth..."

Everyone gave a valid reason, and they all seemed quite reasonable.

However, Ye Wenjie poured cold water on everyone's hopes: "The interstellar communication method we are using is essentially electromagnetic waves. It will drift in the vast universe for four years, and there is a risk of it being intercepted. Therefore, the duration of this launch cannot be too long, and the content is limited to 100KB."

With a data capacity of 100KB, audio is immediately excluded, since sound, as an information carrier, occupies a large amount of memory.

The only remaining direction is text.

100KB converted to text is approximately 150,000 words.

The use of text as the information carrier for this launch was quickly agreed upon, but the organization members had different opinions on which famous essay or biographical novel should be sent.

Just then, Liu Chuan interrupted everyone:

"Aren't you all overthinking this? Our project is called 'Pacifier,' right? What is a pacifier? For babies, it's the simplest and most effective way to stimulate dopamine secretion. While your suggestions are all valid, have you considered that the requirements might be too high?"

Imagine you come home after a long day. Do you want to pick up a philosophy book on the shelf and rack your brains to figure out the meaning of human existence, or do you want to pick up a joke book and enjoy some lighthearted fun without thinking?

Is it acceptable to feed a worker only boiled radish after work?

The others fell silent, frowning as they indicated they were thinking.

Liu Chuan, being straightforward, asked Ye Wenjie directly, "Commander, what do you choose?"

"A joke book."

Ye Wenjie did not hesitate for a moment.

Liu Chuan asked Zhang Zhi'ao the same question again, "If you were to go to sea, what would you choose?"

I also choose the latter.

"That solves everything, doesn't it?" Liu Chuan spread his hands, picked up a cigarette and sniffed it. "The Trisolaran civilization and Earth's civilization don't have a deep understanding barrier, so we'll choose the texts that can best touch people's hearts and express emotions directly, and publish them in large quantities and continuously."

"Engineer Liu," Zhang Zhi'ao couldn't help but interject, "what kind of writing are you referring to? Short stories or novellas?"

"No, no, it's too hasty to release these now. The most suitable content to release right now is a diary."

"journal?"

"right,"

Liu Chuan nodded. "Elementary school student's diary."
