Friends who enjoy Chaoshan beef hotpot should have some impression of the dish Xiong Kou You (beef tallow near the heart).

It is a layer of fat membrane near the cow's heart.

And generally, only big and fat cows have it.

Many people consider this Xiong Kou You as the most delicious food, a must-order on the table, and it is not very expensive.

A piece of Xiong Kou You melts in the mouth, fully welcoming the aroma of beef tallow... cough, sorry for going off-topic.

In short.

The substance produced after the collision of the Tier Four Demon Beast and the Thunder Tribulation is extremely white and bright, almost identical in appearance to Xiong Kou You.

Of course.

This is just a description of its appearance.

This unknown white substance is obviously a completely different concept from Xiong Kou You.

Returning the focus back to the laboratory.

Although another substance has appeared that is clearly not so easily analyzed, from Lin Li to the ordinary researchers, almost everyone was excited.

That's how it is with scientific research.

Amidst a pile of black boxes, one does not fear changes.

One fears the motionlessness akin to stagnant water.

At this moment.

Looking at this oil-like white substance, it was the not particularly related specialist, Zeng Gu Cheng, who first opened up some wild ideas:

"Old Lin, do you think this thing could be some kind of insect egg?

Like those things in sci-fi movies, a silently creeping blob alien that hugs your face?"

Lin Li pondered for a while, then nodded slightly:

"Theoretically, it's possible, but we need to test it further to know the exact situation.

If it is some kind of biological egg.

We should be able to detect some signs of life, and its composition should have a lot of protein—unless it's not a carbon-based lifeform."

Saying this, he looked at Wang Qiang and asked:

"Xiao Wang, is there any feedback on the marking solution?"

Wang Qiang quickly glanced at the screen and shook his head:

"No signs of any reaction, and the thermal imaging equipment also detected no temperature changes."

Thermal imaging equipment.

This term has been heard by people more or less in everyday life, but not many truly understand it.

In fact.

Its accuracy is related to temperature resolution, also known as the equivalent noise temperature difference.

This is its technological core or rather its foundational support.

The lower this value is, the higher the accuracy.

The equivalent noise temperature difference of ordinary thermal imaging equipment is around 50MK, while professional second-generation optical detectors are around 20mK.

The current military-grade third-generation detectors can reach 1MK.

The thermal imaging equipment in the laboratory has an equivalent noise temperature difference of only 0.2mk, theoretically capable of detecting a temperature change interval of 0.0004 degrees.

With such a level of detection equipment and such a close distance, the accuracy of the detection results is quite high.

Then Lin Li thought for a moment and ordered:

"Xiao Wang, begin the composition analysis."

Wang Qiang nodded:

"Understood."

As Wang Qiang turned back to enter the closed operating room, Zeng Gu Cheng looked somewhat curiously at Lin Li:

"Old Lin, why do you have Xiao Wang doing these operations now?

I remember in the early years, you personally handled these critical stages.

Why, have you suddenly achieved great enlightenment in life, with no desires or pursuits?"

Zeng Gu Cheng's words were clearly a jest between acquaintances, normally something to laugh off.

However, surprisingly.

Lin Li was rarely silent for a few seconds.

Then he spread his fingers and placed them in front of Zeng Gu Cheng.

It was clearly visible.

Although there was no external load, Lin Li's little finger and ring finger were faintly trembling.

Operating the mechanical arm under such conditions could likely result in big issues.

Seeing this.

Zeng Gu Cheng was momentarily stunned, and his smile suddenly froze.

He then recalled that this person, who was the overall head of the Fire Camp, was already sixty-four years old this year.

Then he also touched the calluses on his own hands, glanced slightly at Zhuo Yuanxin beside him.

With a faint sigh:

"We're all getting old..."

At this moment, Wang Qiang was unaware of the conversation happening behind her, as her full attention was focused on the flesh sample.

Despite the current white tissue appearing lifeless.

Given past instances where the demon beast's flesh exploded into blood, Wang Qiang and the others remained sufficiently cautious.

She first used rays to transilluminate and analyze the white lipid material.

After confirming its basic properties were relatively stable and no internal chemical changes were occurring.

This bizarre new sample was transferred to the observation platform.

Very soon.

Wang Qiang manipulated a micron-level sampling needle, which gently 'bit' into a baywhite substance like a mosquito's mouthpiece.

The sample collected by this sampling needle is not large, only one-tenth the size of a grain of rice.

With poor lighting conditions, it might be indistinguishable to the naked eye.

However, with current technological standards, collecting such a tiny sample is basically no different from collecting a chunk of meat.

The extracted white substance was quickly placed in a containment dish, while a close-range camera synchronized its image on a display monitor.

Considering Zeng Gu Cheng's proposal about insect eggs, Wang Qiang naturally first tested for protein.

It was mentioned in the junior high textbook.

The general method for detecting protein is using the Biuret reagent,

because protein peptide bonds can complex with Cu2+ in alkaline solutions, forming a purple-red compound.

But this method is macro-validation, requiring quite a bit of sample for comparison.

And sometimes errors may occur.

Therefore, Wang Qiang chose another method:

Pull-down target protein spectral identification.

Pull-down mainly uses highly purified and enriched bait protein to capture target proteins with weak interactions or low abundance in cells.

This is currently one of the most efficient identification methods.

Moreover, it can identify not only proteins but also simultaneously analyze the content of biological salts and the like.

Though the Pull-down technique seems intricate, in fact, its efficiency is as fast as a pregnancy test.

Results are ready in less than two minutes.

Wang Qiang's voice slowly came through the loudspeaker on the command platform:

"Professor, the target sample has a low protein content, and very little biological salt content, essentially ruling out the possibility of being a carbon-based biological egg."

This result was within Lin Li's expectation, so he quickly continued with further instructions:

"Good, proceed to the next research step, direct analysis of the substance's component content."

"Understood!"

Wang Qiang continued to pass the sample to Ren Yongcun to proceed to the next stage of testing.

As a culinary-heavy nation,

Bunny people have quite abundant and precise methods for detecting lipid substances. Only Neon can compete with us.

Similar to Pull-down.

All done in less than half an hour, Wang Qiang and her team had a brand new result.

Subsequently, Wang Qiang returned to the command platform with the report and handed it to Lin Li:

"Professor, the results are out."

Lin Li took the report and glanced at it, his eyebrows furrowed:

"The triglycerides, free cholesterol, acetyl-CoA carboxylase index of the white substance are not much different from ordinary animal fat.

Just that there are many solidified tiny particles?"

Wang Qiang nodded slightly, her tone somewhat grave:

"These particles are even smaller than nano-fat, and what's strange is....

our mass spectrometer can't detect any of its components."

Lin Li looked at her with a peculiar expression and let out a low 'hmm':

"Why?

It's understandable if detailed component analysis can't be done, there are indeed many things locally that we still don't understand their detailed components.

But a solid particle shouldn't be completely undetectable in basic components, should it?"

Just as Lin Li described.

The concept of unknown substances not only exists in the Damo Realm, but is generally present locally too.

For instance, the Tenakal amber imide group.

Before 2013, this was considered a standard detectable but incompletely analyzable compound, only determined to have a piperidine group.

Similarly, within a pregnant woman's umbilical cord, there are currently not less than forty types of unidentified substances.

But no matter how challenging a substance is to analyze, as long as it is solid.

The existing technological level can still detect some information.

For example, chemical characteristics during anion injection.

Or fundamental elemental spectra, etc.

Therefore, strictly speaking.

When a compound substance is discovered, it is not entirely unknown.

The resolution is simply 99% or 9.9%, that's all.

Facing Lin Li's inquiry.

Wang Qiang sighed, somewhat dejectedly saying:

"Professor, I understand what you mean.

Theoretically, what our naked eyes can see is representative it can reflect light.

If it reflects light, it is technically possible to collect its spectra for analysis.

But strangely, the spectrum of these particles cannot be measured.

While we can observe these particles through a microscope, and microwave detection can register clear surface protrusions.

Yet when we employ microneedle sampling, we hit a blank space.

Moreover, various ions, particles, and rays we have tried, and the result.....

still cannot deal with it."
