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

A few hours later, several long, faint blue flames spewed out from the bottom of the "dusty" Xuannv No. [-], and slowly landed on the ground.

"Attention Xuannv No. [-], don't open the hatch!"

Lu Yongchang, who learned that Xuannv No. [-] had returned, put down half of the work in his hands, and took over the command in protective clothing.

"We need to fully disinfect Xuannv No. [-]!"

Bai Yixuan and others naturally understood Lu Yongchang's approach.

After all, they are carrying alien life from Mars.

Although it has been "disinfected" by cosmic rays and the atmosphere, it is basically impossible for unknown life forms to remain on the cabin shell.

But in the face of potential danger, no matter how careful it is, it should be done.

But... Bai Yixuan and the others realized their youthfulness the moment they saw the disinfection equipment.

I saw a few fire trucks parked next to Xuannv No. [-].

The next moment, a high-concentration disinfectant was sprayed out of the fire engine's faucet, completely drenching the entire Xuannv No. [-].

After spraying high-concentration disinfectant three times in succession, they were greeted by several large flamethrowers.

Although he knew that these flames would not cause any damage to Xuannv No. [-], a few drops of cold sweat still rolled down Bai Yixuan's forehead as he sat in the cockpit and watched the flames heading towards him.

"Professor Lu...don't be so exaggerated..."

Hearing the voice from the radio, Lu Yongchang looked serious.

"Because we don't know if the disinfectant is useful for alien creatures, we can only use the simplest and most brutal way to disinfect them!"

"..." Bai Yixuan wiped the cold sweat off his forehead with his hand, "Then we..."

"You?" Lu Yongchang was stunned for a moment, then said, "After the whole body is disinfected, we will conduct 14 days of isolation and observation!"

PS. The rating problem of this book... Tomato changed the scoring system, and I don’t know why it dropped from 9.3 to 8.3. However, after the recent increase in volume, there are indeed many readers who read for less than 10 minutes. review...

Chapter 133 Slice Observation

After the external disinfecting work was completed, Bai Yixuan and the others breathed a sigh of relief.

"Attention Xuannv No. [-], do not leave the cabin after opening the hatch, the samples will be collected by someone!"

Lu Yongchang's command voice came from the radio.

then……

A few minutes later, Bai Yixuan and the others sat blankly in the driver's seat, watching several staff members in tight protective clothing enter the cabin and carry all the samples out.

"team leader……"

Hong Fan's voice was full of sorrow: "The script shouldn't be like this?"

"Shouldn't we be attending the celebration banquet at this time?"

"Ahem..." The corners of Bai Yixuan's eyes twitched again, "Don't, don't worry."

"Maybe we can have a big meal when we get to the isolation point!"

As soon as the words fell, several staff members wearing protective clothing and carrying medical kits walked into the cabin.

Seeing "Dabai" walking straight towards them, the faces of the six astronauts became stiff.

"Captain Bai Yixuan, please cooperate."

"We need to conduct a comprehensive inspection of you."

As he said that, the leading staff member opened the medical box and took out a bunch of bottles and jars.

"Please provide urine, stool samples, etc. Blood tests are required."

At the end, the staff member added: "These are all arranged by Professor Lu."

Hong Fan looked at the various instruments in front of him with a pale face, and swallowed slightly.

"Please ask, after these inspections are over, can we have hot pot?"

Several staff members paused slightly, then raised their heads to look at Hong Fan.

Even through protective masks and masks, Hong Fan felt the smiles in the eyes of several staff members.

"What are you thinking about?" The leading staff member said angrily, "There is a special diet in the isolation point. In order to prevent accidents, you can only eat specific foods during these 14 days."

"What's more, such an examination must be carried out every day for 14 days, which is also to eliminate the interference of diet on the test results."

The six Bai Yixuan: "..."

……

Xiaguo First Laboratory, Biological Sub-Lab.

As a newly built laboratory, the equipment inside is naturally the latest and most advanced.

After all, the role of the biological laboratory is not only hibernation technology.

The improvement of human genes, the extension of life span, and the treatment of alien viruses or bacteria are all inseparable from biotechnology.

It may not be felt on earth.

But once human beings really enter the universe and become an interstellar civilization, the average lifespan of human beings of more than 70 years is not enough at all.

Wearing protective clothing, Lu Yongchang walked into the laboratory slowly.

"Professor Lu!"

A slightly excited male voice came from a distance: "This way!"

Lu Yongchang's eyes moved slightly, and he quickly looked in the direction of the voice.

Looking at the figure waving at him in the distance, a smile appeared in his eyes.

Even through the thick and tight protective clothing, he recognized the person immediately.

Mao Zhengzhi, an academician of the Chinese Academy of Sciences, is a big name in Xiaguo's biological science circle.

At only 36 years old, he can be regarded as the youngest group of academicians in the Academy of Sciences.

Like Fang Xu, the generation gap between Mao Zhengzhi and him, a 21-year-old young man, is not very deep, and the relationship between them is much more harmonious on weekdays.

Lu Yongchang quickened his pace, walked quickly to Mao Zhengzhi's side, nodded and smiled, "Brother Mao, how is it, have the samples been taken out?"

The "large protective suit" on the opposite side nodded again and again, with a bit of excitement in his tone: "Of course!"

"I've been waiting for you for a long time!"

With that said, Mao Zhengzhi turned around and walked towards an isolation laboratory.

After going through a delicate disinfection process, the two entered a brightly lit laboratory.

Immediately, Lu Yongchang was attracted by the samples on the test bench.

He quickened his pace and quickly walked to the test bench.

Through the protective mask, he carefully studied the creature in front of him.

The whole body is dark brown, and the surface is dry and wrinkled, like a dry branch.

It's just that the degree of distortion of this "twig" is obviously much higher.

The entire "twig" twisted into a ball of wire.

Lu Yongchang frowned slightly, but a suspicion arose in his heart.

This should be its self-protection measures, right?

Lu Yongchang subconsciously picked up the tweezers on the side, clamped both ends of it, and pulled it lightly.

There is a clear sense of resistance.

In order to avoid damaging the sample, he gave up the urge to untie this "thread ball" by himself.

"Before you came, we measured the length." After entering the laboratory, Mao Zhengzhi's tone became serious.

"We have measured dozens of samples in total, and the average length is about 20 centimeters."

Lu Yongchang was stunned for a moment, and subconsciously murmured: "It's so long..."

"Although it has not been confirmed yet, we estimate that this fungus should be similar to mushrooms on the earth." Mao Zhengzhi's voice continued.

Lu Yongchang nodded thoughtfully.

"Have you ever done a slice observation?"

Mao Zhengzhi quickly shook his head: "I haven't had time to do it yet."

Lu Yongchang nodded slightly.

That's right, it only took a few ten minutes for the samples to be delivered, so how can there be such a fast research speed.

It is not bad to be able to measure the basic data.

"Then let's do slice observation first!"

As he spoke, Lu Yongchang reached out to fetch equipment from the side, carefully tore off a little fungal tissue with tweezers, and placed it on a glass slide.

The surface of the fungus is very hard, and he felt extremely obvious resistance during the tearing process.

But there is a saying, great efforts make miracles.

After tearing vigorously, the fungal sample was still torn open.The flocculent tissue inside was exposed.

Then, tile, cover slip, stain…

A series of operations flowed smoothly.

In order to observe the fungal samples accurately, Lu Yongchang and Mao Zhengzhi made several temporary mounts of different parts of the fungi.

When the image of the optical microscope was projected onto the computer screen, both of them froze in place.

"This structure..."

Mao Zhengzhi took a light breath: "It is similar to the fungal cell structure on the earth."

Lu Yongchang nodded solemnly: "It's roughly the same, but there are still some differences."

"At least, it has much thicker cell walls than species on Earth."

"And... haven't you noticed that the cells of this fungus only occupy one-tenth of the size of the entire cell wall?"

While speaking, Lu Yongchang adjusted the magnification of the optical microscope so that it could display more cells.

Mao Zhengzhi was taken aback.

Sure enough, some cells even shrank to one-twentieth the size of the cell wall space!

He instinctively wanted to move the slide so he could see more cells.

"and many more!"

There was some surprise in Lu Yongchang's voice: "They are absorbing water!"

Chapter 134 The fungus that has survived tens of thousands of years

Hearing Lu Yongchang's shout, Mao Zhengzhi's expression changed slightly, he immediately stopped his hands, and turned his eyes to the computer screen again.

"look!"

Lv Yongchang stretched out his hand and tapped on several slightly larger cells: "Look carefully, their volume is slowly increasing!"

Mao Zhengzhi quickly focused his attention on these few cells.

Time passed bit by bit.

Cell size also gradually enlarged.

One of the most dramatically changed cells even doubled in size, reaching one-fifth the size of the cell wall space.

"This fungus is still alive..." Mao Zhengzhi swallowed slightly, "I can't believe it..."

That's Mars!

In such a harsh environment, these fungi can still maintain their activity!

Lu Yongchang's eyes moved slightly, and he turned to look at the researcher beside him: "Please help me to test the age of these fungal samples."

Mao Zhengzhi was stunned when he heard this, but he quickly realized it.

He raised his eyebrows and said in a low voice, "Do you suspect that these fungi have lived for a long time?"
