It's reasonable for me to have a two-way foil for a second-level civilization, right?

However, human civilization has come to this point, and the demand for quantum long-distance communication technology has reached its peak.

It is no exaggeration to say that without long-distance communication, the development speed of human civilization will drop several notches!

After struggling briefly for a few minutes, a flash of determination flashed in his eyes.

Fight.

He didn't believe that this time the result would be the same as last time.

No matter how bad it is, just lie in bed for a few days and it will be over!

After thinking clearly, he quickly focused on the extremely dim icon at the top of the technology tree.

After a short wait, the familiar dizziness and burning sensation flooded my brain.

The dizziness is getting stronger and stronger.

The familiar black scene came again.

boil...

Lu Yongchang couldn't help laughing bitterly in his heart.

I'm going to faint again.

Is this fatal quantum long-distance communication so difficult?

Thinking of Su Yutong in the office, Lu Yongchang sighed silently in his heart.

I guess this time, I'm going to scare her again...

In just a short moment, countless thoughts flashed through Lu Yongchang's mind.

But at the moment when the dizziness reached its peak, a touch of ecstasy rose in his heart!

A long-lost reminder finally appeared in his consciousness!

【Photon】

Feeling the countless inspirations bursting out of his mind, Lu Yongchang completely fell into a coma with a satisfied smile on his lips.

……

"Drip! Drip! Drip!"

The familiar buzzer sound and the familiar smell of disinfectant.

Lu Yongchang struggled to open his eyes.

Looking at the surrounding layout, a wry smile appeared on the corner of his mouth again.

There was the sound of the door opening.

"Professor Lu, this is the second time you have been unconscious."

Looking at the somewhat familiar face, Lu Yongchang frowned slightly: "You are... Doctor Wen?"

Doctor Wen in a white coat froze for a moment, then nodded with a smile: "Yes, it's me."

"I didn't expect Professor Lu to have such a good memory. It seems that this coma didn't cause much damage to your brain."

The corner of Lu Yongchang's mouth twitched.

What does this mean?

He took a deep breath and shook his dull head slightly: "Doctor Wen, how long have I been in a coma this time?"

Dr. Wen smiled and handed an inspection report to Lu Yongchang: "Not much, just 24 hours. Compared with the last time, it has made great progress."

Lu Yongchang: "..."

He always felt that the doctor in this article was targeting himself, but he couldn't find sufficient evidence.

"Look, here is your inspection report."

Lu Yongchang's eyes moved, and he looked down at the document in front of him.

"According to the examination, your brain activity level is higher than last time." Dr. Wen said in a flat tone, "Although I don't know how you did it, it is undoubtedly a good thing for you and human beings."

Chapter 175 Quantum Communication and Long-distance Communication

Lu Yongchang looked at the document in front of him silently, and his guess about the function of the system was verified again.

Sure enough, this system is subtly improving one's physique, and the focus of improvement is on the brain.

Seeing Lu Yongchang's silent appearance, Dr. Wen chuckled lightly.

"Don't worry, the result of this test, except for zero, is only known to me and the chairperson."

Lu Yongchang nodded slightly.

He wasn't worried that this so-called secret would be known by others to cause suspicion, but, just to be on the safe side, the fewer people who knew about this "abnormal situation", the better.

Now it seems that the chairman of the congress has already settled all aspects of the matter for him.

"That's right." Lu Yongchang asked again, "When can I be discharged from the hospital?"

"Huh?" Dr. Wen raised his eyebrows lightly, "In such a hurry?"

"You just woke up from a coma, logically, you'd better rest and observe for a day or two."

"...Can I be discharged from the hospital today?" Lu Yongchang said after pondering for a moment, "I need to do a very important research."

"It's about the future of humanity."

Finally, he added.

Doctor Wen's expression suddenly became serious.

She didn't speak, but turned her head to look at the various indicators on the instrument at the side. After confirming that there was no problem, she nodded: "Okay, if that's the case, I won't keep you."

"However, there is one more thing to remind you."

While skillfully reaching out to take out the indwelling needle on his body, Lu Yongchang cast doubtful eyes on Dr. Wen.

"The one who sent you here is Su Yutong, right?" Doctor Wen had a meaningful smile on his lips, "The little girl was crying so badly, are you sure you don't want to comfort her?"

Lu Yongchang nodded with a wry smile.

"Okay, thanks for the reminder."

……

"Ling, call Fang Xu for me." Wearing a loose white coat, Lu Yongchang hurried down the bright corridor, and said in a deep voice, "By the way, there are also Mo Zeyang and the others. All researchers in the quantum field gather at the main laboratory immediately!"

As soon as the voice fell, Ling's holographic image instantly appeared beside Lu Yongchang, drifting forward with his speed.

"Professor, academician Mo Zeyang and his researchers are studying the architecture of the next generation quantum superconducting computer, do you need to remind him?"

Lu Yongchang did not hesitate at all: "Let him put down what he is doing and come to the main laboratory immediately!"

"Okay, Professor!"

Zero's holographic image dissipated in the air as points of light.

……

main laboratory.

"Academician Mo, what do you think Professor Lu asked us to come to the main laboratory for?"

A researcher approached Mo Zeyang and asked in a low voice.

Mo Zeyang looked at the familiar faces in front of him, with some doubts in his eyes.

"I don't know, but it seems that the researchers who came here are all researchers in the quantum field..."

The researcher's eyes lit up, and he asked eagerly, "Could it be that, what does Professor Lu think about quantum computers?"

Mo Zeyang looked at a gray-haired old man in front of him, frowned, and shook his head slightly: "Probably not."

"Did you see that, academician Tang Wenshan, a master in the field of quantum communication."

"I reckon, this time it's for quantum communication."

As he spoke, he quickly took a few steps forward, stretched out his hand and stretched out his right hand to the gray-haired old man in front of him: "Old Tang, it's a pleasure to meet you, long time no see."

The gray-haired old man heard the voice and quickly raised his head.

The moment he saw Mo Zeyang, a gentle smile appeared on the old man's face.

"Academician Mo, hello, hello!"

The right hands of the two were instantly held together.

"I've heard about your recent achievements." The old man said with a smile, "I never thought that such a brat back then would now be the leader of quantum computers."

"Mr. Tang, don't tease me." Faced with Tang Wenshan's praise, Mo Zeyang quickly lowered his posture, "I didn't learn this from you. If it weren't for you, I guess I would still be in some research institute." You are bitterly working as a researcher!"

The researcher on the side: "..."

have been offended.

"Mr. Tang, do you have any news?" Mo Zeyang approached Tang Wenshan and asked softly, "Professor Lu called you over, are you planning to start in the field of quantum communication?"

Tang Wenshan frowned and shook his head slightly.

"I don't know that either."

"I only received zero notifications, and I estimate that everyone present should have only received zero notifications."

"Specifically, we still have to wait for Professor Lu to come."

As soon as the voice fell, the door of the laboratory opened quietly.

Lu Yongchang, who was wearing a white coat and a hospital gown underneath, appeared in front of everyone.

"..."

For a while, the scientific researchers in the main laboratory all looked strange.

"cough!"

"Yongchang, you are..." As the deputy, Fang Xu naturally took the lead in reminding him.

Seeing Fang Xu "pointing fingers" at him, Lu Yongchang's eyes flashed a trace of doubt.

When he looked in the direction of Fang Xu's finger, his face suddenly became embarrassed.

I came out in such a hurry that I forgot to change my clothes.

"Cough cough!"

Lu Yongchang coughed twice, relieved the embarrassing atmosphere and said: "Everyone, I called you here to solve a major problem."

"This is related to the future development and destiny of mankind!"

Hearing this, everyone's eyes became serious.

Seeing that everyone's attention was diverted from his hospital gown, Lu Yongchang calmly buttoned the buttons of his white coat to cover the inside of the hospital gown.

As Lu Yongchang's deputy, Fang Xu naturally noticed his little tricks.

Fang Xu: "..."

Lu Yongchang naturally noticed Fang Xu's strange look.

He glared at Fang Xu silently, gave him a warning look, and continued talking as if nothing had happened.

"Ultra-distance communication technology, I believe you have all heard the name."

"At present, the huge communication delay has become a huge obstacle restricting the further development of human beings."

"Humans want to escape the solar system and become a real interstellar civilization, and long-distance communication is an inevitable threshold."

The moment he heard this term, Academician Tang Wenshan frowned instantly.

"Professor Lu, are you planning to use quantum communication technology to realize long-distance communication?"

The moment he saw the questioner, Lu Yongchang raised his eyebrows slightly.

"Yes, Mr. Tang, you are a master in the field of quantum communication, what do you think about this?"

Tang Wenshan frowned and fell silent.

After a long time, he struggled and said, "I think it may be very difficult to achieve long-distance communication with the help of quantum communication."
