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

a few hours later.

The little white mouse, Aurora, shrank tremblingly in the corner of the cage, her little black eyes filled with fear.

Squeak! (You know how my hours passed?!)

"How? Has the result come out?"

Lu Yongchang's voice came from a distance.

After hearing this voice, Aurora shrank her thin body again.

"Part of it has come to fruition!" Mao Zhengzhi's voice was full of excitement.

"As we guessed, there is an unknown antibody in Aurora's body."

"It is this antibody that solves all those proteases!"

Lu Yongchang snapped his fingers lightly, his eyes sparkled with excitement: "Okay!"

"Is the antibody isolated?"

Seeing Mao Zhengzhi nodding, Lu Yongchang's eyes became more excited.

"Quick, go try the effects of these antibodies!"

As he spoke, Lu Yongchang pouted his mouth at the fifteen experimental group mice lying on their backs in the breeding cage in the distance.

……

Mao Zhengzhi carefully pushed a little of the liquid medicine in the needle into the mouse in front of him.

Because antibodies are currently scarce, they have to save some.

As for the tens of millions of little white mice outside...you can only depend on fate.

Thinking of this, the light in Mao Zhengzhi's eyes dimmed a bit.

As a biologist, although he knew that these mice would eventually die in the laboratory, but when he thought of killing nearly [-] million mice with his own hands, he felt a strong sense of guilt in his heart.

"Crack!" Lu Yongchang reached out and patted Mao Zhengzhi's shoulder lightly.

As the person who made the decision, he knew Mao Zhengzhi's state of mind better than anyone else.

He sighed slightly: "You don't need to feel guilty, this is my order after all."

"If, if there really is such a thing as fate, I should also repay this debt!"

Mao Zhengzhi shook his head gloomyly, but didn't say anything.

"Don't worry, after the experiment is over, I will apply to the chairman of the council to set up a monument for these mice." Lu Yongchang said with a serious expression, "Human civilization must never forget them!"

Hearing this, the guilty expression on Mao Zhengzhi's face became a little less.

He opened his mouth, wanting to say something more, but his attention was attracted by the scene in front of him.

"Yongchang!" Mao Zhengzhi exclaimed loudly, "Look! Wake up! No. 1 white mouse has woken up!"

Lu Yongchang quickly looked at the breeding cage in front of him.

Sure enough, the paws of the little white mouse labeled No. 1 twitched slightly, and a pair of small black eyes opened.

In just a few seconds, the No. 1 white mouse has turned over and sniffed in the breeding cage with its nose arched.

Lu Yongchang smiled a bit: "Yes, it seems that this antibody can indeed solve this strange protease inside the Martian fungus!"

……

While waiting for the other 14 mice to wake up, Lu Yongchang sat on a chair and slowly closed his eyes.

Driven by his thoughts, he entered the technology tree system space again.

The white light spot spread rapidly, lighting up a dim cursor.

[Hibernation technology: preliminary mastery! 】

Then, a light spot extended from the cursor.

Seeing this scene, Lu Yongchang was slightly taken aback.

and also?

After the hibernation technology, is there any technology?

The light spot gradually dimmed, and a cursor with only about 10% brightness appeared in front of his eyes.

[Overweight state balance technology: deep sea mode]

Lu Yongchang subconsciously focused his attention on this cursor.

A burst of dizziness came.

That familiar feeling made Lu Yongchang panic.

Good guy, he won't faint again, will he? !

Not so much, right? !

Perhaps because the system continued to strengthen the brain and body, the dizziness lasted for a few seconds and then slowly disappeared.

As the dizziness disappeared, a hint of enlightenment slowly emerged in the depths of his mind.

It turns out that this technology...

Starting from Xuannv-[-], aerospace planes, or starships, have become faster and faster, and at the same time, their acceleration capabilities have also become stronger and stronger.

The acceptable limit G value for professionally trained astronauts and pilots with the help of anti-G suits is about 12G.

But the G value that ordinary people can accept is only about 3-4.

This is a bit too small for interstellar travel.

Even if the future starship can really reach the so-called 1% or 10% of the speed of light, the acceleration time it needs is unimaginable!

What's more, bearing a large G value for a long time is extremely unfriendly to the human body.

A few minutes may be better. Once the time is extended to several days, months, or even years, I believe no one can bear it.

Therefore, humans need a technique to balance internal and external pressures under supergravity conditions.

That is, the deep sea mode given by the system.

The so-called deep sea mode is actually a bit similar to breathing in water.

This technology has actually been studied a long time ago.

Perfluorocarbons (PFCs) fluids.

It has extremely strong oxygen dissolving capacity.

Therefore, some people try to use this liquid instead of air for "underwater breathing".

But the reality is cruel.

Perfluorocarbon liquids are extremely dense compared to air.

It is simply impossible for normal human lung capacity to breathe it normally.

Even if the lung capacity is large enough to breathe, if all the fluid cannot be excreted from the body, humans will quickly die of pneumonia and a series of complications.

After sorting out a series of knowledge points in his mind, Lu Yongchang sighed slightly, and slowly opened his eyes.

Chapter 139 Code Name: Tower of Babel

"you're awake?"

As soon as Lu Yongchang opened his eyes, he heard Mao Zhengzhi's voice.

"How is the little white mouse?" Lu Yongchang subconsciously asked.

Mao Zhengzhi smiled and pointed to the breeding cage beside him: "Here, they are all awake and in good health. No sequelae have been found so far."

Lu Yongchang subconsciously turned his head to look.

He breathed a sigh of relief when he saw the fifteen little white mice jumping around alive and kicking.

"Next, it's some routine operations."

"Synthesize this protease artificially and manufacture antibodies in batches..." Mao Zhengzhi said with a relaxed face, "By the way, this protease and antibody haven't been named yet, do you want to give it a name?"

"... Let's call it hibernin and anti-hibernin." Lu Yongchang frowned and said with some headaches.

As a waste of names, he really couldn't think of any nice names.

Mao Zhengzhi naturally looked at Lu Yongchang with a speechless face, and muttered to himself: "If I knew it earlier, I wouldn't let you name it. What a bad name it is..."

The corner of Lu Yongchang's mouth twitched, and he changed the topic.

"Currently the technology is not mature enough, so we will do experiments on chimpanzees first."

"Remember, make sure it is safe before applying it to humans!"

"In addition, there is another research task for you." Seeing Mao Zhengzhi's slightly contemptuous eyes, Lu Yongchang rolled his eyes and said in a deep voice, "Deep sea mode, have you heard of it?"

……

Beijing.

familiar office.

"Sir, I am applying to start the space elevator project."

Lu Yongchang stood in front of the desk and said in a deep voice.

Hearing this, the old man looked a little dazed.

He slowly put down the teacup in his hand: "Space elevator?"

"If I understand correctly, what you're talking about is the kind of elevator that can go directly to space in science fiction movies?!"

Even though he has become the chairman of the People's Federation, the old man couldn't help exclaiming: "This thing, do we have this technology?"

Lu Yongchang shrugged and shook his head quickly: "Of course not."

Seeing the gradually weird look on the old man's face, Lu Yongchang quickly added: "Oh, by the way, I'm talking about now."

Hearing this, the expression on the old man's face not only did not ease, but became even weirder: "What do you mean...you already have a clue?"

Lu Yongchang nodded quickly, and at the same time stretched out his hand to make a gesture: "After studying this period of time, I have a little clue."

Mr. Li: "..."

He raised his wrinkled right hand, gently held his forehead, and then sighed deeply.

It's that statement again.

If he believes this again, he will be a ghost!

"Since you said so, the project should be launched." Mr. Li said angrily, "What? Do you want me to approve funds for you now?"

Lu Yongchang sneered, a trace of "shyness" flashed in his eyes.

"Chairman, I'm not here to ask you for money."

Mr. Li raised his eyebrows slightly, and took a sip from his teacup: "Then what do you want?"

"The top scientific research talents in the Asian region have basically been concentrated in your laboratory."

"As for the American division and the European division... They are a bit troublesome over there, and it may take some days before they can come."

The smile on Lu Yongchang's face became more and more awkward.

"Chairman, I have come to ask you for a piece of land."

"Land?" Mr. Li breathed a sigh of relief, "Isn't it just a piece of land? Why do you ask me for such a trivial matter?"

"How much are you going to need, what are you going to build, you can find someone to declare it and it's over, really... Is there anyone still stuck with you now?"

While talking, the old man shook his head helplessly while drinking tea.

Lu Yongchang: "...the land I want may be a bit large, and it will be used to build the foundation of the space elevator."

"At least the size of a normal-sized city, and it needs to be near the equator."

"Pfft! Cough cough cough!" The old man coughed hard.

The expression on Lv Yongchang's face became more and more embarrassing, and he tried to explain: "I plan to rely on this space elevator to build a space port. By then, Luanniao-[-] aerospace carrier can be manufactured in the space port, which can save a lot of trouble. So... this space elevator might be bigger."

Mr. Li frowned slightly.
