Jiang Cheng snorted disdainfully.

"Something she'd do. After Jiang Cheng finished speaking, he indifferently withdrew his gaze that was originally looking at Lan Keyue.

Lin Yijin sighed lightly, lowered her head, but the corners of her mouth were slightly hooked, seeing that Jiang Cheng and Xu Xuehui were both dissatisfied with Lan Keyue, her heart was full of joy.

But there was still an understanding look on his face, and he whispered to the two: "Oh, don't say that, she is my cousin anyway, let's not see her being ruined." ”

Jiang Cheng dotingly raised his hand and touched Lin Yijin's long hair, trying to persuade him.

Xu Xuehui, who was behind the two, spoke first, stopped Lin Yijin's compassionate thoughts, and said: "Yijin, you are too kind, do you look at her like that, like someone who can listen to persuasion?"

Jiang Cheng nodded in agreement, but he was also afraid of hurting Lin Yijin's heart, and his tone softened a little: "You both have to stay away from her, look at her like that she is a scheming girl, don't be hurt by her." ”

"It's all quiet!" Professor Fan stepped into the classroom and scolded, and the bell rang as if pinching something.

Everyone didn't dare to relax, picked up the textbook, and listened to Professor Fan's lecture upright.

"Everyone has done a good job in the homework assigned to you before, especially in the area of cultural relics appreciation, many students have their own unique opinions. Before the end of class, Professor Fan suddenly asked a question to the students present: "In the archaeological field, the damage caused by the oxidation of cultural relics has always been the most difficult problem in the industry.

When facing Professor Fan's question, everyone lowered their heads one after another, and subconsciously refused the opportunity to make eye contact with him, as if they were afraid that they would be careless, so they called their own names.

However, it is precisely because all the reactions are like this that Professor Fan is extremely dissatisfied.

He patted the podium table with gravity, glanced at the students present with a majestic expression, and scolded in a deep voice: "What? Young people nowadays are young and vigorous in everything they do, and answering questions one by one is like taking a break?!"

As Professor Fan said this, everyone's heads were buried lower again, looking at each other secretly, everyone hoped that someone would stand up and save everyone now.

"Teacher, I can answer. Under the expectation of everyone, Jiang Cheng raised his hand, his face full of confidence.

He's not a showman, but in this case, he doesn't allow himself to sit still.

But Professor Fan didn't even look at Jiang Cheng, he just raised his hand and motioned for him to sit down: "You sit down, I know you have good grades, but I don't want you to have only the name Jiang Cheng in your history department!"

After speaking, he flipped through the roll call book on the podium table, took a general look, and then selected one of the names: "Jia Jinglun, Jia Jinglun will answer." ”

But for some reason, when Professor Fan mentioned Jia Jinglun's name, several people secretly laughed, which attracted the attention of Lan Keyue, who was sitting behind them.

"Teacher, Jia Jinglun didn't come!" The snickering people kindly reminded Professor Fan.

"Rotten wood can't be carved!" Professor Fan frowned, threw the roll call book on the podium table with dissatisfaction, and then directly fell his gaze on Lan Keyue: "Lan Keyue, you come." ”

However, when Professor Fan called Lan Keyue's name, there was a sigh in the audience, and they were all secretly mocking Lan Keyue's previous cheating.

Although this matter was only settled in the end, everyone thought that Lan Keyue must have achieved results by cheating.

The reason why Professor Fan named Lan Keyue's name was to test Lan Keyue's strength, and secondly, it was only because there were not many students he could remember, and Lan Keyue was one of them.

"What are you arguing about?" Professor Fan scolded with a cold face, then looked at Lan Keyue and motioned for her to answer.

Lan Keyue got up, didn't take those people's ridicule of her to heart, and answered Professor Fan's question calmly: "There is no real standard answer to your question, and even the existing equipment cannot guarantee that the protection of cultural relics can be foolproof. ”

"Isn't that the same as not saying it? Lin Yijin muttered to himself.

Her voice was not loud, but she didn't expect to be listened to by Professor Fan.

"This classmate, it seems that you have a different opinion?" Professor Fan turned his head and looked directly at Lin Yijin and asked rhetorically.

Lin Yijin's heart trembled, she didn't expect that her unintentional words would attract Professor Fan's attention.

Jiang Chengsecretly cheered for Lin Yijin, which gave Lin Yijin the courage to stand up from his seat and answer Professor Fan's question: "Teacher, I think the reason why the cultural relics are oxidized is because the oxygen in the soil is lower than the oxygen in the atmosphere before the unearthing, and the oxygen in the atmosphere will be removed in a large area after the unearthing, and the rapid oxidation will occur. ”

Although Lin Yijin did not dare to look directly at Professor Fan's gaze, he still answered the questions calmly and easily.

"That's a good point. Professor Fan bowed slightly, and praised Lin Yijin without hesitation.

Just when everyone thought that Professor Fan was going to criticize Lan Keyue instead, they didn't expect Professor Fan to ask her, "What do you think?"

What does that mean?

Everyone looked at each other, completely unable to understand Professor Fan's thoughts.

Lan Keyue just raised the corners of her mouth and replied politely: "I can't say that she is wrong, but she is not right either." ”

What's going on?

Everyone was at a loss again, but there were also people who were upset for Lin Yijin.

Unexpectedly, Professor Fan showed a satisfied look at Lan Keyue's words, and motioned for her to continue.

Lan Keyue nodded, and explained in a flat tone: "Cultural relics are actually undergoing the process of oxidation when they are buried underground, but because the oxygen in the space is relatively scarce, and most of the ancient tombs have high humidity and high CO2 concentration, these are the conditions that contribute to the oxidation of cultural relics. ”

Lin Yijin was already dissatisfied with Lan Keyue talking about her like that, and even directly retorted: "Then according to what you say, those cultural relics should have been oxidized and damaged long ago before the drawings were made!"

Lan Keyue raised her eyebrows, the smile on the corner of her mouth deepened a little, turned her head to look at Lin Yijin, and kindly analyzed it to her: "That's the case, all we can see is its appearance, in fact, a large number of organic ingredients have decayed, if they are not effectively protected before unearthing, large-scale contact with the air in the later stage will lead to rapid oxidation." ”

Lin Yijin was stunned when she heard this, but looking at Lan Keyue's calm face to answer this question, it seemed to be mocking her for her indiscretion, which made her subconsciously clench her fists and glared at Lan Keyue.
