The moment he finished speaking, Lü Yongchang felt a slight dizziness rising from the depths of his consciousness.

The dizziness was not intense and lasted only a short time.

But the information it contains is something he cannot ignore.

Without the slightest hesitation, he leaned back in his chair and closed his eyes.

Her eyelids firmly concealed the faint orange-yellow light beneath her eyes.

"Yongchang?"

Fang Xu looked at Lü Yongchang's unusual actions with a bewildered expression: "What are you doing...?"

A dull response followed: "Let me think about it."

...

Consciousness quickly descended and arrived in the familiar yet unfamiliar space of the technology tree.

Against the backdrop of the mottled tech tree, a dazzling orange-yellow light shines through.

On the side of the pristine white technology tree, a cursor with an orange-yellow background appeared—[Thought Imprint].

Every change carries a strong sense of warning.

Lu Yongchang's heart sank slightly.

He had the privilege of seeing this technology tree model once.

Unlike this time, the tech tree space turned blood red that time.

Human cloning technology.

In the standards of the technology tree, that is truly dangerous technology.

"Ideological imprint..."

Lu Yongchang stared at the orange-yellow cursor and murmured softly.

As the name suggests, this is the technology he just envisioned.

By implanting a false memory fragment into the consciousness of an intelligent being, one can gain control over the intelligent being's thinking.

"Is this also considered dangerous technology...?"

He muttered to himself and focused his attention on the orange-yellow cursor.

Just like the cloning technology of the past, the development history of several civilizations appeared in his mind as clearly as a movie.

His gaze gradually became complicated.

...

More than ten minutes later.

Under Fang Xu's gaze, Lü Yongchang opened his eyes with a complicated expression and exhaled a long breath.

It was slightly different from what he had expected.

[Thought Imprint] is not a dangerous technology.

If forced to categorize it, Lü Yongchang would prefer to call it a secondary dangerous technology.

The difference between the two is also very simple.

Dangerous technology is something that no single civilization can possibly mitigate the negative impacts of.

This civilization will eventually perish under its influence.

While such dangerous technologies could also lead to the destruction of civilizations, that is only a high-probability event.

This means that there will always be a few exceptionally gifted civilizations that can overcome the negative effects of the "thought imprint" and rely on it to achieve rapid development.

Risk and reward are always commensurate.

[Ideological Imprint] The high risks inherent in technology will inevitably bring high benefits to civilization.

Just like the Cleaners civilization—if it truly controls its subordinate civilizations through [thought imprints].

“Yongchang.” Fang Xu stared at Lü Yongchang’s constantly changing expression and said carefully, “This technology has a very high potential risk.”

Lü Yongchang nodded silently: "I know."

"Controlling the thoughts of intelligent beings carries considerable risks."

"It could even lead to the demise of civilization."

Fang Xu hesitated, then said, "Then you..."

He wanted to persuade Lü Yongchang to give up the technology.

“It needs to be studied.” Lü Yongchang did not give him the chance. “Although the risks are high, human civilization needs this technology.”

"It will bring new impetus to the development of human civilization."

"Enough to drive human civilization to expand rapidly to level six, or even level seven!"

"As for the risks..."

"If the cleaners can safely master this technology, then we certainly can too!"

A wry smile immediately appeared on Fang Xu's face.

He had guessed that this would happen.

From the moment we first stepped off Earth, human civilization, under the leadership of Lü Yongchang, has been gambling on that elusive glimmer of hope.

A Level 5 civilization, seemingly very powerful.

However, Fang Xu, who had witnessed the civilization of the "Painting" and the Cleaners, did not believe that human civilization could rest easy.

Therefore, although he emotionally opposed the proposal, Fang Xu rationally supported Lü Yongchang's decision.

"I'm going to the biology lab right away."

Lu Yongchang stood up from his office chair, took off the loose white research coat next to him and draped it over his shoulders: "The management of the Academy of Sciences is temporarily entrusted to you."

"You should be very experienced in this area, so I won't waste any more time."

"good."

Fang Xu responded briefly.

...

【Earth】

Human Union First Biological Laboratory.

The tightly closed door suddenly opened, attracting the attention of many researchers.

"Professor Lü?"

"Good day, Chief Lu!"

A series of exclamations filled with deep surprise rang out.

Lu Yongchang smiled and nodded to everyone, then asked directly, "Where is Academician Mao?"

"Professor, Academician Mao is studying the Italian web data that was just transmitted back."

Some familiar voices came from the side.

"I remember you! You are..."

"Lu Siyuan?"

Lu Yongchang's smile grew even wider: "Mao Zhengzhi mentioned you to me."

"Well done."

A faint blush appeared on Lu Siyuan's face after receiving praise from Lü Yongchang. He raised his hand, gently touched the tip of his nose, and said somewhat shyly, "It's all thanks to Academician Mao's guidance."

Lu Yongchang looked at Lu Siyuan with great interest and joked, "Your nose-touching gesture is not much different from Mao Zhengzhi's."

"You've learned it that thoroughly?"

As soon as he finished speaking, a suppressed laugh rippled through the crowd.

Seeing Lu Siyuan's face getting redder and redder, Lü Yongchang laughed and waved his hand, "Alright, I won't tease you anymore."

"Take me to Mao Zhengzhi."

"I have a big research project here!"

Upon hearing this, Lu Siyuan's eyes lit up, and the shyness on his face instantly disappeared: "Really?!"

"Professor, please come with me!"

...

Half an hour later.

Mao Zhengzhi frowned, tapping his fingers lightly on the lab table in front of him, and unconsciously making clicking sounds.

Clearly, Lü Yongchang's demands caused him great distress.

"Very difficult?"

A questioning voice came from the side.

“Professor…” Mao Zhengzhi shook his head with a wry smile, “This level of difficulty cannot be described simply by the word ‘high’.”

"I understand what you mean, influencing people's thinking patterns by implanting fragmented memories."

"Theoretically speaking, this is indeed feasible."

"But in practice, it's probably not that simple."
