Xiong Beibei scratched his head.

Moreover, even if he drank coffee and played games for 24 hours, he believed that if he used this time to study, he would not be able to master so many skills.

Xu Xinyi was thoughtful:

“Could it be that Chen Ting is holding a mobile phone every day and is not playing?

Is this just learning these professional knowledge? "

The two looked at each other again, but saw the realization in each other's eyes.

It’s connected!

Put that way, everything makes sense!

No wonder Shen Ting looks at his phone every day!

at the same time!

Director Dama, Shao Ming, Shen Ting and others have already discussed how to further identify the blood in the wooden house.

Shen Ting has no appraisal qualifications, so naturally he cannot make a direct appraisal.

Just like the previous collaboration with Director Xiao Ma to identify spores and pollen, Shen Ting provided methods and guidance.

Director Dama will evaluate the feasibility of Shen Ting's method and, if it is feasible, will personally perform the appraisal.

This is currently the most efficient method that does not violate the rules.

Got unanimous approval from everyone!

Shen Ting and Director Dama put on their appraisal uniforms and entered the appraisal room.

Everyone else was waiting outside.

It can be seen that everyone's faces have very complicated emotions.

There are two core emotions:

Expectations and worries!

I hope that Shen Ting can complete the appraisal and bring a new breakthrough to the leather maker's eight-year-long unsolved case.

But he was also worried that Shen Ting would not be able to complete the appraisal.

Or, the special substances identified are not special enough, just like cinnabar, beeswax, and meteoric phosphate.

at the same time!

The police officers found that Director Dama in the identification room also had a look of doubt on his face.

If Chen Ting wanted to identify spores and pollen now, with the preparations made by his brother Director Xiao Ma, he would naturally cooperate with all his strength.

Although there is a small overlap in the identification methods between trace evidence and palynology.

But fundamentally, these are two completely different disciplines.

The core difficulty of palynology is the identification of spores and pollen, and the mastery of a large amount of knowledge about spores and pollen.

Trace evidence involves a wide variety of substances, and naturally requires more knowledge of the material characteristics.

And they can be called trace evidence, because both the volume and quantity are usually smaller than pollen and spores.

The difficulty of identification is naturally higher.

The core research content of trace evidence experts is to use what instruments and identification techniques to better separate and identify trace evidence in different scenarios.

It can be said that trace evidence is the most cutting-edge discipline in physical evidence identification.

Director Dama, although he is the director of the identification office, he can only say that he knows a little bit about the identification of trace evidence.

Shen Ting's words...

"First, identify this peak and the corresponding special substance."

Shen Ting took out an infrared spectrum chart and pointed at one of the peaks.

Just this one point made Director Dama immediately look serious.

He was now certain that Shen Ting really understood trace evidence.

Because the peak that Shen Ting pointed out was one of the two special substances that he discovered that might exist.

And in the entire appraisal room, he was the only one who could see that there was something wrong with this wave peak.

Therefore, this one finger can prove that Shen Ting's eyesight is not inferior to his.

"Sample 3, Sample 8, and Sample 11 should all contain this substance.

Let’s try to separate first…”

Under Shen Ting's guidance, Director Dama immediately took out sample three and started the operation.

The whole process was much more complicated than Director Dama had expected.

At the same time, the shock on his face became more and more obvious.

Previously, when Shen Ting pointed out the abnormal peaks in the graph, Director Dama had already determined that Shen Ting's eyesight was not inferior to his own.

At this moment, as Shen Ting issued one instruction after another, Director Dama once again confirmed that Shen Ting was indeed proficient in trace evidence.

And his level is definitely higher than his.

"The separation is almost complete."

After about half an hour, Director Dama finally separated a small amount of yellow crystals.

It can only be seen clearly under a high-power microscope.

"First, use the infrared spectrometer..."

"And then put on the gas chromatograph-mass spectrometer..."

After several rounds of appraisal of the crystals, Shen Ting looked at the appraisal report with some surprise:

"Looks like a cyclic sulfide crystal?"

Shen Ting pondered for a moment, then took out the blood sample map and pointed to another peak:

"Let's start separating the second special substance!"

Director Da Ma next to him already had a look of disbelief on his face.

Looking at the enlarged ring structure on the A4 paper, his eyes widened.

The hands holding the A4 paper were even shaking slightly.

It was actually identified?

So smooth?

At the same time, hearing Shen Ting’s words, Director Dama nodded repeatedly:

"good!

This is also the second special substance I discovered earlier."

The two began to separate and identify again...

The police officers outside the appraisal room were also surprised by the change in Director Ma's expression...
