"You piece of trash, don't talk nonsense and slander others." Sun Lina was terrified that her thoughts were exposed, and she stood up and cursed furiously to conceal her guilty conscience.
Zhao Jiajun was infuriated as well, and he suddenly grabbed Chen Yu, shouted furiously in exasperation. "If you dare talk nonsense, then I'll surely tear apart your stinky mouth."
Chen Yu dodged and looked at the two with ridicule. "Wu Yang is sick, be careful not to be infected."
"What?" Sun Lina's heart thumped as if she had fallen into an ice cave. She denied it vehemently, "Bullshit, I have nothing to do with Wu Yang. If you dare to slander me and ruin my reputation, I won't let you off!"
Chen Yu sneered and said, "Yesterday afternoon, I personally met Wu Yang at the hospital. You know best of yourself. How dare you say that I slandered you?"
"You..." Sun Lina had been feeling uncomfortable today. Did she really get that kind of weird disease? The question was, how did Chen Yu know it so clearly?
As if he'd seen through her thoughts, Chen Yu continued. "Don't worry about how I found out, think about how to explain it to Zhao Junjun firstly."
At this time, Zhao Jiajun's face was livid, and the guilty was written on Sun Lina's face. Even a fool could see that what Chen Yu said was close to the truth. Otherwise, her reaction would not be so big.
Feeling his head turning green, Zhao Jiajun asked in disbelief, "Lina, are you really having an affair with Wu Yang?"
"Jiajun, don't listen to this bastard's nonsense, I swear I absolutely didn't cheat you." Sun Lina hurriedly denied with a worried expression.
The quarrel between the three was very loud, and all the students in the classroom heard it. They were surprised, confused, excited, and watching the fun. They whispered to each other.
Chen Yu no longer paid attention to the two and turned around to prepare for class. "Dogs bite dogs, you two can fight at will, as long as you don't disturb me..."
"Class begins!" At this moment, a 60-year-old old man in a formal suit walked in with a serious face. He was Niu Liqun, an antique appreciation professor.
He was of noble character and high prestige. As soon as he entered the classroom, the noisy classroom immediately quieted down. Even Zhao Junjun and Sun Lina, who were arguing, closed their mouths.
Mr. Niu carefully put a cloth bag on the podium, but he did not open it immediately. He called the roll first and then gave a lecture.
The lesson was about the appreciation of ancient jade. Chen Yu was fascinated and had learned a lot of new knowledge. Now he had eyes to distinguish truth from falsehood, but his basic theoretical knowledge was too lacking.
"Theoretically, that's all. Now, let's practice," said Mr. Niu. He opened the cloth bag and took out a palm-sized dragon-shaped jade.
"This is the Song Dynasty Jade Artifact I specifically bought from the antique market. I'll let you guys appraise it and see if you can master the knowledge I taught you."
When Chen Yu raised his head, a string of information appeared. It was a nephrite from the late Qing Dynasty, worth between ¥30,000 and ¥40,000.
Nephrite was divided into different colors, namely white jade, green jade, black jade, and yellow jade. Among them, green jade was the most common, which was relatively low in value.
He couldn't help but wonder. Mr. Niu said that the dragon-shaped jade was from the Song Dynasty. Judging from its appearance, it looked like a poor fake, but the superpower of the eyes told him that it was real. Was there any other trick in it?
Mr. Niu looked around the audience and his eyes fell on Zhao Jiajun intentionally or unintentionally. He appreciated Zhao Jiajun's ability and focused on training him.
Zhao Jiajun argued with Sun Lina in a low voice for half a class. He was not in the mood to listen to the lecture at all. Suddenly, he found Mr. Niu looking at him. He thought that Mr. Niu was angry, so he hurriedly stood up and said, "Let me appraise."
After that, he went up to the podium, took the dragon-shaped jade, observed it carefully, and understood it.
Zhao Jun's father and grandfather were both in the antique business. They came from an antique family and had been influenced by it since childhood. Before he went to college, he had learned a lot about antique appreciation.
He said confidently, "I'm sure this jade is a fake. The technique of making it old is very low-level. It's not worth mentioning at all."
"Oh, tell me your basis." Mr. Niu nodded approvingly.
"It's very simple." Zhao Jiajun was a little proud and temporarily forgot about the trouble with Sun Lina. He said with assurance,
"First of all, the shape of this dragon-shaped jade artifact is awkward. Its normal shape should be two parallel claws. As for this dragon-shaped jade, it is supported by its tail and front claws. Its rear claws are much shorter.
On the surface, the paste was rough and was baked with acid. Even without using a magnifying glass, one could see that the acid white membrane was uneven in color. The genuine color wouldn't be uniform, but would slowly seep in bit by bit and gradually form.
From the look of the carving, this dragon-shaped jade should be a relatively rough machine in modern times. The lines were rigid, especially the eyes, which were completed with two simple lines.
"Generally, ancient jade is made by carpenters, so the round lines will connect instead of being smooth at one go. Moreover, the surface of this carving is not a distinct triangular one, so it is a rough imitation."
Zhao Jiajun listed several points in a row, and then stopped, ready to enjoy the professor's praise and his classmates' exclamation.
Sun Lina flattered Zhao Jiajun, acting like a love-struck fool. She didn't forget to mock Chen Yu at the same time. "You're so knowledgeable, how do you know everything? You're not like someone that only knows how to spread rumors and is extremely despicable."
Chen Yu had already understood why this fake dragon-shaped jade artifact that looked like a fake was actually the real deal. When he heard Sun Lina's ear piercing words, he sneered in his heart.
"Since you're so aggressive, don't blame me for putting your boyfriend in an awkward position."
However, he did not make trouble right away. He waited for Mr. Niu's opinion to see if the old professor did it on purpose or if he made mistakes of treasure appraisal.
Mr. Niu nodded with appreciation and said, "Very good, Junjun is very smart. He pointed out many shortcomings of this fake jade. It is worthy of praise. He deserves to be the head of Class. He is worth learning from!"
Mr. Niu's words confirmed his attitude and announced the authenticity of the dragon-shaped jade.
The students who followed him were discussed, "Zhao Junjun is so knowledgeable. How can he know everything? His future is really promising!"
"Of course! His grandfather and father are dealing with antiques, so it's naturally not difficult to appraise an ordinary jade..."
Hearing the praise from the audience, Zhao Jiajun couldn't help but become complacent.
"Guys, don't envy me. Today, I'll tell you the simplest way to identify ancient jade. In the future, you will be like me and won't be confused by antiqued methods!"
Hearing that Zhao Jiajun seemed to be explaining his unique skill, the students immediately pricked up their ears. They had never been so serious in class.
"The way is to encounter a piece of jade that is suspected to be made of acid. Licking it slightly, if it is sour, it is fake. Of course, antiques will inevitably have bacteria. Everyone here is dignified and wouldn't do something like that."
When he spoke up to here, Zhao Jiajun looked at Chen Yu with a detestable gaze as he teased. "Chen Yu picks up trash all day long and isn't afraid of being dirty. I suggest he ascend the arena and lick the dragon-shaped jade and then describe his feelings."
