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

Chapter 14 I Don’t Cheate My Father, I Cheate My Grandfather

"Professor Liu, you mean: every weekend?"

"Yes, every weekend."

"I've troubled Teacher Sun so much and disturbed her rest. I feel so bad!"

Liu Rong was so angry that she laughed: "Lin Sicheng, don't be so ungrateful: Xiao Sun is a Peking University PhD, so many people want her guidance but can't get it!"

"I know, but Professor Liu, there's really no need... I promise I can write a good thesis."

Liu Rong said nothing, just staring at him. There was a hint of suspicion in his eyes, and there was no room for doubt.

Lin Sicheng was helpless: "Professor Liu, seriously, I promise to study hard in the future. As long as it's your class, I promise to listen carefully to every one of them."

"Haha, you said that before. Did you listen carefully?"

Lin Sicheng was speechless: That was all the fault of my previous life.

I didn't expect that even after being reborn, it could still be blamed on me?

But you can't really come to make up for the lessons every weekend, right?
What, no supplement?

Lin Sicheng could imagine that in the future, whenever he had classes on "General Theory of Archaeology" and "Scientific Expeditions", Professor Liu would pay special attention to him, asking him to stand up and listen in every class, and even asking him to answer every question.

The company is dead.

But if you want to make up for it: half a day is enough for him to visit Xiaodongmen or carve a Han Dynasty clay pot.

What’s more, it’s only half a day a week?
Lin Sicheng sighed and made up his mind: "Professor Liu, my grandfather actually thinks highly of you. He said that you are responsible, gentle and patient, and have a good temperament. Your lectures are organized and focused..."

Liu Rong was stunned for a moment, his eyes wide open: "Lin Sicheng, your flattery is useless!"

"I'm not flattering you!" Lin Sicheng swore. "So starting from summer vacation, Grandpa has been giving me extra lessons, focusing on 'General Theory of Archaeology' and 'Scientific Expeditions'. I basically understand all the key points, so I didn't pay much attention today..."

Liu Rong sneered: "Lin Sicheng, do you think I will believe it?"

"Really!" Lin Sicheng pointed at the lesson plan. "If you don't believe me, ask!"

real or fake?

Liu Rong was skeptical and exchanged glances with the teaching assistant.

If you want to accuse Lin Sicheng of lying, the lesson plan is on the table and you can find out by asking.

But if what he said was true... When Liu Rong thought of his test results at the end of last semester, he wanted to hit someone.

After thinking for a moment, she nodded: "Xiao Sun, if you want to ask, ask about the uranium series method!"

"Good teacher!"

Assistant Professor Sun picked up the lesson plan and flipped it open. "What is the principle of the uranium series method?"

"The radioactive imbalance between the parent uranium-238 and uranium-235 and the decay chain daughter thorium-230 and protactinium-231 is compared to estimate the age of the deposition."

“Main methods and time span?”

“钍-230法：1万至40万年，镤-231法：5000至15万年。综合范围：几十年至100万年的年轻地质样品。”

Oh, you really made up for it?
Assistant Instructor Sun was stunned for a moment, and Liu Rong waved her hand, meaning that it was her turn.

“Applicable scenarios!”

"Relatively closed environmental systems: karst cave deposits, submarine lake deposits, volcanic rocks and fossils, and subterranean Paleolithic sites."

“Advantage!”

“It can solve the long-term dating needs that cannot be covered by the carbon-14 method.”

"It can be applied to inorganic samples without organic matter."

"It is possible to detect chronological faults caused by secondary displacement of sediments."

Liu Rong's eyes lit up: "Limitations!"

Lin Sicheng paused and said, "Professor Liu, this seems beyond the scope of the syllabus."

I'm only a senior, and you're asking me questions about graduate studies?

Liu Rong snorted coldly, rolled up the lesson plan, and pointed at him.

Lin Sicheng sighed helplessly:
“The initial conditions are difficult to determine; there is no guarantee that the decay rate will remain constant in the end;

There is no way to ensure that the environment is closed, controlled, and free from external interference; nor is there any way to ensure that the samples are free from subsequent uranium contamination or daughter loss.

“Solution!”

"It needs to be cross-validated with other isotope precision measurement methods, such as paleomagnetism and fission track analysis..."

Liu Rong opened his mouth, not knowing how to praise.

Really, even if Xiao Sun were to come, his answers might not be as comprehensive and accurate as his.

So, he didn't lie: Professor Lin gave him extra lessons.

But those words definitely weren't said by Professor Lin, at least not all of them...

Subconsciously, she recalled the scene when she was a graduate student and Professor Lin was standing on the podium and talking eloquently and humorously.

After a long time, she put down the lesson plan and sighed softly: "Not bad." Assistant Teacher Sun blinked: More than just good?

The second half involves knowledge content for graduate students. Lin Sicheng can answer it so comprehensively, which shows that he definitely has a deep understanding of it.

Could it be that Professor Lin wants him to apply to be Professor Liu's graduate student?
She was just thinking about it, but Professor Liu asked, "Does your grandfather want you to apply to be my graduate student?"

Lin Sicheng shook his head decisively: "He never said that!"

It is impossible to pass the postgraduate entrance examination. At most, you can study for a master's degree after graduation.

"Well, I'll ask him after that. But you can't neglect your other classes either. The postgraduate entrance exam is different from other classes. It's useless to ask anyone for help!"

Liu Rong paused for a moment, then smiled again, "But don't worry too much. If the score difference isn't too big, there are other ways..."

Lin Si's heart skipped a beat: I didn't say I wanted to take the postgraduate entrance examination?
But this is only secondary. The key point is Professor Liu’s expression and tone: I always feel that he is a little too kind?

This is Master Liu, the dean gets a headache just seeing her.

Lin Sicheng felt a little flustered and took the opportunity to say goodbye: "Professor Liu, are you busy now?"

"it is good!"

Liu Rong actually stood up and walked him to the door.

Lin Sicheng's heart skipped a beat: I always feel like something is wrong?

Lin Sicheng went downstairs in a daze, and the more he thought about it, the more he felt something was wrong: if it was just because he and his grandfather were colleagues, he would definitely not care about him so much.

Even if we add in the friendship between him and his grandfather as teacher, it would still be impossible. At least he would not take the initiative to arrange for Assistant Teacher Sun to give him extra lessons.

They will not blatantly say things like "Even if the scores are a little lower, there are still other ways."

why?
After thinking for a long time and still unable to figure out the reason, Lin Sicheng took out his phone.

Grandpa should be at Xiaodongmen Market, the phone was a little noisy.

"Grandpa, let me ask you something!"

"Haha... got into trouble?"

"No, I just want to ask, what is your relationship with Professor Liu like?"

There was a sudden silence on the phone.

Hang up?
He took the phone: Not broken?

Then why don’t you speak?
Just as I was suspicious, the old man sighed: "Why are you asking this?"

Lin Sicheng was stunned for a moment: No... I haven't told you who it is, why are you sighing?

According to normal logic, shouldn’t grandpa ask: Which Professor Liu are you talking about?
As far as Lin Sicheng knows: there is one in the Archaeology Department, one in the Cultural Relics and Museums Department, two in the Cultural Relics Protection Department, and even more in the Office of the Academy and the Academic Affairs Center... In the School of Heritage alone, there are at least ten professors with the surname Liu.

How did Grandpa know who he was asking? The key point was, why was his tone still the same?
In an instant, Lin Sicheng's eyelids twitched.

"Just...just...just asking!"

"Let me put it bluntly: Did you get scolded, or did you fail the test?"

Lin Sicheng didn't know what to say.

For no apparent reason, Professor Liu took the initiative to ask the teaching assistant to give her extra lessons and even persuaded her to apply for her graduate program.

The key point is, still so kind?

The question is, since when did kindness begin?

It seems like I just made up some nonsense, saying that my grandfather gave me extra lessons during the summer vacation:

Professor Liu, my grandfather highly respects you...

They say you have a very good personality, gentle and patient...

And you have a good temperament...

Lin Sicheng's scalp tingled: It's over...I'm afraid I've dug a trap for the old man?
"Lin Sicheng, speak!"

Lin Sicheng gritted his teeth:

"I was distracted in class today, and Professor Liu gave me a good scolding. He even said I'd have to make up for it. I had no choice but to say a few nice things about you: saying you praised her for being serious and responsible, having a gentle personality, and also praising her good temperament..."

There was no sound on the phone again.

After a long time, the old man sighed and said, "Lin Sicheng, go home tonight!"

As soon as he finished speaking, there was a "beep" sound and the phone was disconnected.

Lin Sicheng stared at the phone screen with wide eyes: I actually guessed it right?

The man is a widower and the woman is a widow. Why didn’t it happen in the previous life? There wasn’t even a hint of it?
Grandpa should have some worries.

Never mind, the trouble has already happened, so let it be.

Anyway, I absolutely cannot return to this home, at least not in the short term...
