Reborn Treasure Appraiser: I Really Didn’t Want to Be an Expert

Chapter 32 I’m leaving now!

The sun was just setting and the hands were pointing to five o'clock.

"Squeak", the laboratory door was pushed open and Lin Sicheng walked in.

Feng Lin and Xu Bo subconsciously raised their heads.

Isn’t this the student I met in the restaurant this morning?
Xu Bo frowned: "Who let you in? Get out!"

Lin Sicheng was stunned for a moment: No, are you fucking crazy?

Wang Qizhi followed closely behind Qi, holding the iron certificate in his hand.

He took a look and said, "Xiao Xu, go off work first!"

"Ah, Professor Wang? I'm sorry, I didn't know it was you..."

"Get off work!"

Wang Qizhi's expression was somewhat serious. Xu Bo no longer dared to argue and took off his gloves.

As soon as the person left, Wang Qizhi looked at Feng Lin and asked, "How did you recruit them?"

Feng Lin lowered her head: "Professor Wang, I'm sorry!"

She also didn't expect that Xu Bo was so jealous.

No supervisor would like such a personality, because no one wants to have another Zhu Ling in his or her laboratory.

"Professor Wang, I will go to the Teaching and Research Center to re-coordinate tomorrow!"

"Yeah!" Wang Qizhi's expression eased a little. He put down the iron tile and waved again, "Come!"

Just come.

Lin Sicheng took off his coat, put on protective clothing and entered the infrared reflectance imaging room.

Feng Lin was startled.

The equipment inside costs several million dollars, and even Xu Bo is not qualified to touch it. At most, he can just do some plastering.

She hurried over: "Student Lin, do you need help?"

"Don't worry about him!" Wang Qizhi waved his hand, "You take notes!"

With the tutor's arrangement, Feng Lin didn't dare to say anything. She just took the folder and pulled out the form.

But I was really worried and kept my eyes fixed on the surveillance camera.

He turned on the machine to preheat, then threw the iron tiles into the refrigerator and began to set the parameters.

"Radiation rate 0.07!"

"Blackbody source calibration: humidity 10~40HR, temperature difference -20℃ to 150℃."

"Pseudo-Rainbow Mapping: Iron Red Mode!"

Feng Lin suddenly raised her head and stared at Wang Qizhi: No... he actually understands?
The emissivity is fine, but since I am not a graduate student related to cultural heritage protection, how would I know about black source calibration and pseudo-rainbow mapping?
Not to mention adjusting parameters, I can't even understand these two words.

Wang Qizhi nodded at the table: "Why are you looking at me? Are you taking notes?"

"Oh~"

She lowered her head, glanced at the monitor, and copied quickly.

Wang Zhiqi was also very surprised.

Lin Sicheng said that he had been to Professor Lin's laboratory more than once, and he explained it clearly and logically, and he definitely understood the basic instrument operation procedures.

Otherwise, Wang Qizhi would not let him into the equipment room.

What Wang Qizhi found strange was Lin Sicheng's casualness, relaxation, and familiarity.

He doesn't even need to turn his head to know where the dashboard, tray, light source and display are.

Just take a glance and you will know how much the angle differs and how to adjust it.

It would be impossible to be so skilled if you haven't been in the laboratory hundreds or thousands of times.

There is no need to compare with others, even Feng Lin next to him seems to be a little worse than him.

No, it should be much worse. This guy has already started testing:

Multi-point scanning, dynamic monitoring...

Image animation, annotation, matrix data export...

Heat map overlay, precise defect location...

Linear temperature difference represents identification, analysis...

Wang Qizhi was stunned.

As the saying goes, different trades can be like different worlds. For both metal cultural relics, there is a huge difference between copper restoration and iron restoration, let alone ceramics?
Don’t think that even if you use the same testing instrument, the operating procedures and required conditions are very different.

So Wang Qizhi is ready to give guidance at any time.

But before he could give any instructions, Lin Sicheng had already completed most of the test. Hey, something's not right... Why is the exported image so weird?
Wang Qizhi blinked. "Surface-penetrating combined imaging of iron artifacts... No, where did he learn that?"

Feng Lin next to him widened her eyes.

It's no exaggeration to say that she really can't do what Lin Sicheng is doing now: combined imaging of iron artifacts. This instrument does have this function, but she has never learned it.

To be more precise: Xida doesn’t teach it.

There is only one university in the country that offers relevant courses: Peking University School of Culture and Art.

And only postgraduate students involved in the protection of iron cultural relics will learn...

The two were stunned when Lin Sicheng's voice came from the microphone: "Record!"

"Rust ingredients: FeO, FeO..."

"Middle and bottom layers: α-FeOOH, β-FeOOH, γ-FeOOH..."

"Hydroxides: Fe(OH), Fe(OH)... Chloride compounds: FeCl, FeCl..."

"Sulfates: FeSO...Carbonates: such as FePO..."

Feng Lin's head was in a mess. He picked up the pen, but couldn't remember anything.

Finished?

This was Lin Sicheng's inference based on visual inspection, and it was not displayed on the instrument at all.

The key point is that she was distracted for a moment and didn't remember any of them.

Just when I didn't know what to do, Lin Sicheng came out of the imaging room carrying the iron tile.

Wang Qizhi looked skeptical: "Where did you learn penetrating imaging?"

“In the book!”

What the hell?
"In that book?"

Lin Sicheng took off his protective suit slowly:
Institute of Archaeology, Chinese Academy of Social Sciences, Journal of Archaeology, No. 8, 2006.

"Chinese Academy of Social Sciences, Archaeology, Issue 11, 2006."

"Peking University Museum, Archaeology Research, 2006 Issue 6!"

Wang Qizhi's eyes widened: "Lin Sicheng, what are you talking about?"

Lin Sicheng sighed secretly: It’s not bullshit, but it’s indeed a bit perfunctory.

But we can’t just hide it and not use it, right?

That's a crime you don't suffer, but you're bringing trouble upon yourself.

Besides, it’s not some top-secret technology, right?
Lin Sicheng put down the certificate, put on gloves and a mask, and began to mix the medicine: "Professor Wang, I really didn't lie to you. If you don't believe me, check it out!"

Wang Qizhi moved his lips, and curse words rose to his throat.

Is this a question of whether to check the journal and whether to verify whether there are relevant papers in the journal?
According to Lin Sicheng, if you can learn the most advanced scientific testing knowledge by just flipping through a journal or reading a paper, wouldn't that mean there are scientists everywhere?

But on the other hand: Peking University is the only university in the country that teaches relevant technology. If he didn't learn it from books, where else could he learn it?
Just as he was secretly guessing, a few pungent smells wafted over, and Wang Qizhi narrowed his eyes:
Lin Sicheng was mixing a bunch of bottles and jars together: oxalic acid, acetic acid, citric acid, hydrochloric acid...

Wang Qizhi's eyelids jumped: "What are you doing?"

Lin Sicheng said as if it was a matter of course: "Rust removal?"

"No...why not use ultrasound if you have it?"

“It’s too slow, and I still have to wash it at the end!”

"Then why not use tea? Electrolyte will work too?"

“It takes many times, it’s better to do it in one go!”

I washed and dried it, and then dried it and washed it, but it still couldn’t be dried.

By the time it was washed out, the electric kiln had already arrived.

"One-step approach, what the hell?
Even though different fields are often different, how could Wang Qizhi not understand the harm that acid can cause to metal cultural relics?
In front of him, in his laboratory?
what is this?
This is a blatant insult to a cultural relic protection researcher.

Wang Qizhi was so angry that his liver ached. He grabbed Lin Sicheng and stood up: "Get up!"

Lin Sicheng was at a loss for words: "Professor Wang, I'm really short of money and I need it urgently!"

Wang Qizhi was stunned for a moment, then gritted his teeth and said, "Five hundred thousand!"

"What?"

"Five hundred thousand, I'll put it on your card later!" Wang Qizhi pointed at the door with a dark face, "Get out of here now!"

Haha, how much?
Lin Sicheng had previously thought: Even if Professor Wang is knowledgeable, the maximum he could earn would be 300,000.

What happened next: Professor Wang got angry and the money almost doubled?
He quickly took off his gloves, and with a smile on his face, he bent his waist and said, "Okay, Professor Wang, I'll be out of here right now!"
