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

on the bench.

A small white mouse quietly sank in a bottle of light yellow solution.

On the body of the little white mouse, several catheters were inserted.

According to the location, Lu Yongchang can probably judge the function of these catheters.

It is nothing more than feeding and excreting.

The eyes of the mouse were closed tightly, and the abdomen rose and fell slightly, as if breathing normally in the air.

Mao Zhengzhi tapped the glass bottle lightly.

The crisp sound from the glass bottle woke up the little white mouse inside. It suddenly opened its small eyes with a burst of panic. After seeing that it was Mao Zhengzhi, the little white mouse slowed down again.

"How about it?"

Mao Zhengzhi looked at Lu Yongchang proudly.

Lu Yongchang looked at the little white mouse in the solution thoughtfully, nodded slightly, and sighed from the bottom of his heart: "It's amazing!"

"It's just...why does this little white mouse look familiar to me?" Lu Yongchang frowned slightly, carefully looking at the little white mouse in the container.

"Ahem!" Mao Zhengzhi said with some embarrassment, "This is Aurora's brother, it's normal for you to be familiar."

Lu Yongchang: "..."

Boil!

"Full of Loyalty"

Lu Yongchang shook his head helplessly: "How long has it lived?"

Mao Zhengzhi stretched out his finger and compared a number.

"Two days?" Lu Yongchang frowned, "This time is a bit short..."

"No, it's two weeks." Mao Zhengzhi said happily, with the corners of his mouth raised, "You can never imagine how miraculous this solution is."

"In the words of our researchers, it's like artificial amniotic fluid!"

"Considering the deep-sea model you mentioned, we named this light yellow solution, deep-sea fluid."

A trace of surprise flashed in Lu Yongchang's eyes.

two weeks!

It's been a long time!

"Are there any side effects?"

Lu Yongchang asked in a deep voice.

After all, the sequelae of this underwater breathing experiment are often serious.

Although the underwater breathing experiment conducted in the United States had achieved initial success, in the end the experimenters all died of lung infection.

As for why...

On the one hand, the fluid inhaled into the lungs cannot be completely discharged.

On the other hand, these liquids carry a large number of bacteria and microorganisms on the surface of the human body, and cause infection after entering the lungs.

When it came to the core issue of sequelae, Mao Zhengzhi's expression suddenly became serious.

He turned his head and winked at the researcher next to him, and said in a deep voice.

"So far, we have not found any sequelae."

"After thoroughly disinfecting the body surface of the mice, we also added a small amount of antibiotics to the deep sea fluid."

"In addition, we have strengthened the filtration and purification equipment." As he spoke, Mao Zhengzhi pointed to a machine beside him.

Lu Yongchang walked to the machine curiously, looked it over carefully: "What can this thing do?"

"Professor Lu, don't underestimate it!" Mao Zhengzhi said with a serious expression, "It's all thanks to this little white mouse's ability to survive for two weeks unharmed!"

"On the one hand, it can filter various large-particle impurities in deep sea fluid, such as hair and dander."

"On the other hand, it can reduce the number of bacteria and viruses in the deep sea fluid as much as possible through ultraviolet light, coupled with a small amount of antibiotics, this completely eliminates the problem of infection."

"Additionally, it allows deep-sea fluids to combine with fresh oxygen and expel excess carbon dioxide and other exhaust gases."

Lu Yongchang nodded silently, his eyes full of surprise.

"What about the discharge of deep-sea fluid?"

"If you can't get all the air out of your lungs..."

The smile on Mao Zhengzhi's face grew stronger: "Why do you want to discharge?"

"You mean..." Lu Yongchang's eyes lit up.

"Since we can't let the lungs expel all the liquid, why not let the lungs absorb it?" Mao Zhengzhi smiled and pointed to the light yellow liquid in front of him, "These deep sea liquids are harmless to the human body, and can It is completely absorbed by the body."

"As for the sequelae...maybe you will go to the toilet a few more times after you come out." Mao Zhengzhi shrugged and said in a humorous tone.

At this time, the researcher who had just left hurried back with several breeding cages in his hand.

Chapter 156 Hibernation Cabin Technology

"Academician Mao, I brought a few mice."

The researcher placed the breeding cages in his hand on the experimental table one by one and said softly.

Mao Zhengzhi nodded, thanked him softly, and then said to Lu Yongchang again.

"Professor Lu, look."

"There are a total of 13 mice here, and they have survived in the deep sea fluid for 24 hours to 312 hours."

"So far, we haven't seen any sequelae."

Lu Yongchang leaned down and took a closer look.

"Not bad!"

Lu Yongchang nodded with satisfaction: "Has the gorilla experiment been done?"

Mao Zhengzhi shook his head: "There is not enough time, we are going to start experiments on gorillas next week."

"As for human experiments, we are going to apply to use those vicious death row prisoners."

"Don't worry, let me think about it carefully." Lu Yongchang said after pondering for a moment, "Let me read all the experimental data first."

……

In Mao Zhengzhi's office.

The holographic projection clearly displays the data of the deep-sea liquid and the purification filter device.

Relying on the brain that has been continuously strengthened by the system for a long time, Lu Yongchang has completely mastered this knowledge in just a few hours.

He exhaled slowly and closed his eyes.

Consciousness once again sank into the fluorescent green space.

As the white light spots slowly lit up, the originally dim cursor began to glow bright white.

[Overweight state balance technology: preliminary mastery]

Then, the white light began to extend again.

A slightly dim cursor appeared "in front of" him.

【Hibernation cabin technology】

According to the brightness of the cursor, he roughly estimated it.

80%.

In other words, they have mastered 80% of the so-called hibernation cabin technology.

……

He opened his eyes again, and looked at Mao Zhengzhi who was waiting by the side.

"How is it?" Mao Zhengzhi looked a little apprehensive, like a student waiting for the teacher to correct his homework, "Is there anything wrong?"

Lu Yongchang smiled and shook his head: "There is no problem."

"You did it perfectly."

Mao Zhengzhi heaved a sigh of relief, and a smile appeared on his face again.

"The gorilla experiment can be postponed." Lu Yongchang continued, "At present, what we should consider is to combine hibernin with deep sea fluid."

Mao Zhengzhi was slightly taken aback.

"The reason is very simple." Lu Yongchang didn't hold back, and explained straightforwardly, "At present, our technology is not developed enough."

"Not only that, but there is not enough time for us to develop."

"The interstellar journey takes an extremely long time."

"There are 80 billion people in the world, not to mention all of them, but at least half of them." Lu Yongchang said in a deep voice, "This is the guarantee of future productivity and technology inheritance."

"Billions of people, plus the consumption of hundreds of years... don't say it is 15 years, even if we are given 50 years, we will not be able to build such an exaggerated spaceship!"

"Therefore, we need a hibernation capsule that can provide nutrition, provide protection, and provide various necessary supplies."

"Except for the necessary security personnel, the vast majority of people enter the starship and immediately start a century-long hibernation."

Mao Zhengzhi nodded thoughtfully.

"I probably understand what you mean."

"This technique is not difficult, and I can give you a solution right now."

……

inside the laboratory.

A mouse was injected with a standard dose of hibernin and then placed in a glass container.

The purified hibernin is so powerful that in just a few seconds, the mice entered a state of "fake death".

Afterwards, Mao Zhengzhi injected light yellow deep-sea liquid into it, and then opened the filter and purification device connected to the container.

The instrument is activated and the deep sea fluid begins to circulate.

"Here, now we only need to add some nutrients to it to meet your requirements."

"As for the hibernation life-support cabin you mentioned, we only need to modify the filtration and purification device and design it into a box-shaped container."

Lu Yongchang's eyes showed some doubts.

Is it that simple?

Is the 20% gap in the technology tree system just a matter of container design?

"Wait and see."

He said in a deep voice, "My intuition tells me that it won't be that simple."

……

Obviously, things are not as simple as Mao Zhengzhi thought.

At first, everything went smoothly, and the mice lay quietly in the solution, like a corpse soaked in formalin solution.

But more than an hour later, the mutation happened.

"Academician Mao!" A researcher in charge of monitoring the vital signs of the mice changed his face, "The vital signs of the mice are rapidly decaying!"

"Heartbeat also stopped!"

"Fill it out quickly!" Mao Zhengzhi's expression changed drastically, and he quickly stood up from the seat beside him and directed.

After some tossing, Mao Zhengzhi announced the result with an ugly expression.

"Professor Lu, failed."

"The little white mouse is dead."

Lu Yongchang sighed slightly.

Sure enough, this thing is not that simple.
