Enter the Immortal Cultivation

"It seems like... an animal house?"

Song Shufu's tone was a little uncertain.

Because the current layout of the Empirical Department was the result of a hasty expansion prompted by Ai Qinglan. It was completely different from the layout of the "old Empirical Department" that he had been familiar with for decades.

It's amazing that he can give a rough idea.

"But... why is the animal room so close to the experimental area..." Ai Qinglan's eyes widened: "Aren't you afraid of contamination? In the place where I used to stay, the animal room and the experimental area were two separate buildings."

"Because... I'm poor." A trace of embarrassment appeared on Song Shufu's face: "I also want to build several floors with up-to-standard facilities! One building for the demonstration area, one for the animal house, one... one for the warehouse, and another... Idle! But! I am poor."

Ai Qinglan nodded and accepted the explanation: "Let me just say... the sound yesterday was indeed too loud. It was not like a dozen mice could make it."

"No, it wasn't this close originally. Junior Sister Ai, it's now this close after your expansion..."

As she spoke, she put her hands directly on the wall, using her strength to loosen the bricks. Lime and varnish rustled down, raising a puff of dust.

Regardless of his injuries, Song Shufu jumped up and collected the smoke with his palms: "What are you doing? The medicine is very expensive! The instrument is difficult to clean!"

Ai Qinglan ignored it and stretched out her hand to tap lightly on the brick wall. The wall was stressed and vibrated, causing the bricks to dent or protrude. Ai Qinglan used her thumb and index finger to pull out a brick from the wall.

Surprisingly light.

"Is it these porous, fluffy bricks? Isn't it a load-bearing wall?"

Song Shufu screamed: "You're going to demolish it before you're sure it's a load-bearing wall?"

Ai Qinglan rolled her eyes: "Is anyone here going to be hit by the roof?"

"That's not the problem! Due to the Spirit Stabilizing Formation, the Demonstration Department generally does not bless the foundations and beams..."

"So who will be killed?" Ai Qinglan ignored Song Shufu and continued to focus on demolishing the wall: "Is it really the sound here? This kind of fluffy bricks have very poor sound insulation. And... because it was just built , so there is no sound insulation array..."

Among the crowd, Lao Xie muttered aggrievedly: "Didn't you say that the talisman array that may cause interference can be used without it?"

Ai Qinglan quickly removed a loose opening in the wall. The white ash on the opposite side has also fallen away.

What appeared in front of Ai Qinglan was a transparent cage with an entire wall. Inside the cage were a bunch of black gadgets.

That's a bat.

The black bat was listless and looked like it was about to die. The light passing from the demonstration area startled the bats. The bat directly opposite Ai Qinglan panicked, opened its mouth wide and exposed its fangs, and breathed painfully.

"Bat?" Ai Qinglan whispered.

Bats have a very unique immune function, and many plague viruses are "non-pathogenic" in bats. Therefore, bats have become excellent carriers of various plague viruses.

Song Shufu had previously discovered that a certain kind of glandular plague poison could speed up the course of corpse and horse plague, but the reason is currently unknown. Therefore, bats suddenly became his alternative experimental animal.

It looks like...

Are they seriously ill?

"Junior Sister Ai, what are you doing? The Evidence Department is going to re-equip now." Song Shufu struggled over and walked over. Before he could get close, Ai Qinglan grabbed him and asked, "Senior Brother Song, the scientific name of this kind of bat is What?"

"Little Fu Yi." Song Shufu was frightened by Ai Qinglan and did not dare to move.

"The food habit is insectivory?"

"Well, it's relatively easy to raise...and it eats well."

"Hibernating?"

"Subtropical species don't have hibernation habits, otherwise wouldn't they be disturbed in winter?"

"So..." Ai Qinglan's eyes burned: "It's nocturnal, right?"

"Yes... that's right." Song Shufu nodded: "Um, do you suspect it's the bats?"

--How……

The idea occurred instantly.

Separated by a wall? Shouldn't this be true?

Ai Qinglan asked: "What is the active period of this kind of bat?"

"It started to be active at Youshi and lasted until Yinshi..." Song Shufu's eyes widened: "From Youshi to Yinshi the next day?"

——That naturally includes Xu Shi.

"But why..."

"Well, indeed, why?" Ai Qinglan let go of Song Shufu, curled up her right index finger and pressed it against her cheek: "Although this wall was just added, the sound insulation effect is very poor, but the varnish is of the highest quality. The sealing is very good, which means that it cannot be caused by some volatile components of metabolites in the bat. There are only two possibilities left. "

"One is a clustering phenomenon caused by certain similar molecules; the other is ultrasound."

Children all know that bats rely on ultrasonic waves to sense their surroundings.

It's natural that bats emit ultrasonic waves.

The corpse-refining horse plague cannot infect monks, has a very poor response to the flames of life, and has no spiritual response higher than the background aura. Therefore, it is definitely not the type of beast mechanism cluster that relies on macroscopic clusters to obtain spiritual power and computing power.

Even if this possibility exists, it is definitely very low, so "ultrasound" is given priority.

"So, we can start designing the demonstration again." Ai Qinglan said this, waving to the left and right: "Who will build the wall again? By the way, carve a talisman array to isolate the sound waves - ah, yes, not just Sound waves, even ultrasonic waves, are blocked for me.”

Thus, a new set of empirical evidence begins.

This time, the operation was still the same as the beginning - the central nervous system extract of the Northern Wilderness Red Horse, the buffer, and the pathogenic life source. The only difference was that Ai Qinglan directly removed the polymerase.

Enzymes have extremely strong specificity and can only react to one or a few substances.

Logically, the amplification process of the pathogenic life source does not require polymerase.

The amplification reaction was completed in the water bath pot farthest from the bat.

Among them, half of the reactants were treated with ultrasound - Ai Qinglan only needed to stretch out her finger and flick it lightly on the wall of the test tube. The finger strength and control ability of the monk could ensure that the test tube oscillated at the frequency of ultrasound.

The other half, not.

A new round of reaction began again.

This time, after the water bath pot prompt sounded, Ai Qinglan opened the lid of the instrument.

There was no surprise. The phenomenon of deformation, sedimentation, and porridgeization of the life source that appeared for the first time appeared again.

"Puff." Ai Qinglan smiled: "It turned out to be like this... lucky."

No one expected that Song Shufu would come up with such a result.

It was the bats that helped her find such a result.

And at night, when they were checking the video records of the animal room, they found that their luck was far more than that.

Because...

The picture showed that the night before yesterday - that is, at the time of the first operation by the little apprentice, these poor bats were howling in pain because of the plague.

Of course, there was an ultrasonic component.

The little Fu Yi was small in size and had no strength. However, in order to continue the name of this batch of bats, Song Shufu used a fixed amount of low-level spiritual medicine in the feed to ensure that these little Fu Yi were as healthy as possible without becoming a monster. This made this batch of little Fu Yi itself more alert than their counterparts in the wild. And a few days ago, it happened to be the time when the glandular plague and the corpse horse plague broke out in their bodies. These days they still had strength and cried particularly loudly.

Song Shufu himself was relatively poor, and the cage he bought did not have the function of absorbing noise - some empirical departments would use that method to prevent the spirit of the empirical animals from being in an anxious state.

However, this "loud" was only based on the standards of the little Fu Yi. After passing through the cage and a wall, not much energy was saved.

According to later speculation, the catalytic range was only a few feet close to the wall.

If Song Shufu's apprentice had not done the operation in front of the water bath, if the water bath was not right against the wall, if the bats had not been in so much pain that day that they could not help but make loud noises, then this demonstration would not have been so successful.

Even more so... if the bats on the other side of the wall had not called so hard when the apprentice was operating - if these little things had called a little quieter, then things would have been completely different.

Because of poverty, the reconstruction was hasty; because of poverty, the animal house and the demonstration area were separated by only a wall; because of poverty, the cage did not have the function of absorbing sound waves...

To a large extent, this was Song Shufu's achievement out of poverty.

In response, Song Shufu just smacked his lips.

"Damn it, why do I feel so bad when I say this?"

There is no doubt that they are lucky.

But they don't know how lucky they are.

In another history from the auraless universe that they didn't know about, this process was not so smooth.

Prusiner began to extract prions in 1974. Before that, in the 1960s, British radiologists tried to use ultraviolet rays to destroy the nucleic acid of sheep scabies, and concluded that the pathogenic factor of sheep scabies had nothing to do with nucleic acids - of course, this conclusion was ridiculed by the entire academic community.

After all, this is equivalent to trying to raise an anti-flag against evolution.

The central dogma exists in this way.

It took Prusiner eight years to isolate prions using rodents. Because his evidence was quite convincing, the name "prion" was recognized.

But in the entire academic community, he was still the only one who believed that this process did not require the participation of DNA and RNA at all.

The entire academic community was proving the opposite - the replication of prions must involve DNA or RNA.

And this long-lasting proof alone lasted until 1996.

It is ridiculous to say that the reason why this debate was settled was also due to a strong element of luck.

In 1996, mad cow disease broke out in the UK.

Because capitalists used a large amount of meat and bone meal from dead cows as supplementary feed, mad cow disease spread wildly.

When human lives are at stake, more forces converge in this field. Prusiner's discovery was recognized.

In 1997, Prusiner won the Nobel Prize in Physiology or Medicine
