As soon as Chen Ao finished speaking, Cai Lun's face immediately became careless, he sneered, and said, "What? Brother Chen also knows antiques?" His words were ridiculed and disdained. The Cai family had countless antiques and treasures. Cai Lun was a little interested in appraising treasures. With these treasures practicing, his eyesight was still very unique. How dare a distant relative of a Duke's Mansion questioned his judgment?

Cai Lun was very upset in front of everyone.

Chen Ao smiled slightly and said, "I understand a little bit. This uncensored jade has a good color and looks like a gambling stone. Why don't Mr. Cai look at its texture?"

The so-called gambling stone was called uncensored jade in ancient times. It is considered a kind of uncensored jade. It means that when the jade is mined, it is wrapped with a layer of weathered skin. It is impossible to know the quality after cutting. Most jade has skin, and the thickness of the skin mainly depends on the degree of weathering. The skin is thicker if the skin is high. The raw material of a piece of jade is colored and has a good surface. When the first cut is cut, it will be green, but it may be gone when the second cut is cut. This is also a common thing.

This piece of uncensored jade is very similar to a gambling stone. Even if an insider sees it, he can guess that there is at least one piece of high-quality jade inside. However, Chen Ao once had many jade artifacts, and he could see the name at a glance.

Cai Lun picked up the uncensored jade and looked carefully in his hand. There was nothing special. In fact, in this era without a microscope, most people would not pay attention to the slight texture differences. However, Chen Ao was different. It was not that he had more delicate eyes than microscopes, but in the past, he had carefully compared the color textures of many jade instruments in various optical instruments. Now, with the naked eye, he can still see a little difference.

Different textures will also cause slight changes in the entire color and color. As long as you carefully discover this change, it is easy to distinguish the authenticity.

The students on the side also became interested. Chen Ao walked over and said, "I heard that there was a nation in the north called Qiang people. They began to learn the customs of the Han people hundreds of years ago. For example, jade cicadas, who were born and thought they were wearing pendants, but died. Qiang people were far away in the northern border and lived a hard life, so naturally they did not have any exquisite jade to bury. Therefore, they replaced it with a jade, which is very similar to rough jade, and can be buried without carving. It is very convenient, very practical, and low-priced, and it is not deceptive."

When Cai Lun heard this, it turned out to be a jade cicada. When he remembered that it was a thing that the dead man had in his mouth, he immediately had a cold war. Fortunately, his acting skills were good, and he still looked chic and said, "How can I see this as a Qiang man jade cicada?"

Chen Ao laughed: "This is very easy. If you bite it, if the jade is soft, it will naturally be a Qiang man jade cicada. If the material is very hard and brittle, it will be a gambling stone."

Cai Lun's face suddenly changed. He bite him? He bite your mother, maybe it was taken out from the dead!

But... he insisted that it was a gambling stone. If he didn't dare to bite it, wouldn't it be slapping himself in the face? It was equivalent to admitting that it was a jade cicada. Wow, what should I do?

His face was gloomy and the students looked at him, unable to hold his face, or not? This is a question!

When he closed his fan, he laughed and threw the uncensored jade to the stall owner who sold antiques: "No matter how much the market value of this jade is, I will look down on you, so I will reward you." As he said that, he calmly fanned, still elegant.

Even if there is only one percent possibility of Jade Chan, Cai Lun will never take the risk to try it. But this moment, his smile was a little stiff. After Chen Ao said this, his style suddenly became dim.

"This distant relative of Duke Qi's mansion, hum, one day I will teach him how powerful this young master is." Thinking of this in my heart, Cai Lun took a deep breath, laughed again, and grabbed Chen Ao's hand and said, "Brother Chen is very knowledgeable, and he even knows these things, haha."

Chen Ao was the best at making scenes and said sincerely: "It's far worse than Mr. Cai." The two of them walked side by side, leaving the rest of the prison students behind.

When he arrived at the entrance of the Confucius Temple, several peddlers blocked the way. Cai Lun shook his fan and sneered: "These peddlers are so annoying. There are actually some profit-seeking people in front of the saint's door."

Chen Ao thought to himself: "Your grandfather's father is much greedy, and he has a lot of money and silver at home, so of course he won't seek profit! Why are you so arrogant?" He said: "Yes, yes!" He went over perfunctorily and walked into the Confucius Temple.

In fact, the Confucius Temple in the Song Dynasty was not as grand as those built in later generations, but it had a bit more market atmosphere.

There are sculptures of Confucius in the Confucius Temple, and below are disciples such as Mencius. The statues are vivid and displayed in sequence, showing a very respectful look, serving the most sage teacher in the main hall.

As soon as Cai Lun's eyes fell, he saw a statue in the bottom corner and sneered: "Sima Jun is really worthy of enjoying cold pork, it's so weird." He looked very rude.

Chen Ao went to look at the statue and then looked at the inscription below it, and he understood in his heart that this person was Sima Guang, who was also a powerful minister of the generation and had a great literary talent. After this person died, someone carried him into the Confucius Temple. This shows that his reputation is still very high.

What is the reason why Cai Lun disdains Sima Guang? Chen Ao thought about it and understood that Cai Lun's grandfather Cai Jing was once a capable general of Wang Anshi's reform. When Wang Anshi was demoted and Sima Guang took office, Cai Jing was in trouble. He was so cruel and miserable by Sima Guang. As a grandson, Cai Lun's complaint can be regarded as a revenge for Cai Jing's immortality.

Chen Ao just smiled, but saw a few bachelors with plain clothes and scarves coming on the other side. One of them was handsome and extraordinary and sneered: "If Mr. Junshi is not qualified to enjoy the ancestral temple, is it possible that my brother can enjoy it?"

It's here to provoke. It seems that Cai Lun has met Sima Guang's fans.

Chen Ao smiled and quietly took a step back. He would never participate in this kind of thing. If all the brothers wanted to beat Master Cai, Chen Ao would welcome him, he might as well call him a few more times.

Cai Lun glanced at the people and sneered: "It turns out that they are too students, it's such a coincidence..."

Just as Zhou Heng and other supervisors caught up, the two teams got together and suddenly became tense.

"Oh, it turns out that it is Tai Student. By the way, there is indeed a sachet tied around their waists. The sachet is very strange, as if it was made of ink paintings. Could it be that this is Tai Student's logo?"

The other party smiled slightly: "Brother, what's right, we are studying in the Imperial Academy. I'm not sure what the young master calls me?"

Cheng Hui? Everyone was shocked. Except for Chen Ao, everyone knew that Cheng Hui was the first in the final exam in the Imperial College in the past year. A few days ago, there were many rumors. When the official hosted the Imperial College ceremony, he had personally received him and said many words of encouragement. Many people speculated that this kid would sooner or later become a success, and even if he entered the cabinet, it would not be unexpected.

Cai Lun was not surprised at all, and said unwillingly: "I am Cai Lun."

Cai Lun is also one of the top figures in the Imperial College. He ranked third in the final exam last year. In addition, his family background is prominent, so his popularity is naturally no weaker than Cheng Hui.

Cheng Hui was about to speak, but a tycoon student behind him laughed and said, "Cai Lun? I haven't heard of it. But I heard that there is a man named Wu Bi in the Imperial College who is still good at writing, but I don't know if he is here?"

A murderous aura flashed in Cai Lun's eyes instantly. This student was too rude. Praising Wu Bi in front of him, Cai Lun, was to admit that Wu Bi was the best person to do the Imperial College, not his Prince Cai. This was a deliberate provocation. He sneered: "I wonder who is Brother Tai?"

This man is very rebellious, but his appearance is not outstanding. He has a pockmarked face and a wine nose. A pair of narrow eyes looked at Cai Lun coldly: "Young Master Cai can call me Xu Wei."

"Xu Wei?" Chen Ao seemed to have some impression of this name. He should be the most outstanding among the students. No wonder he dared to mock Cai Lun in person.

Cai Lun laughed: "It turns out it's Brother Xu, very good, very good." He stood with his hands behind his back and said gracefully: "Is Brother Xu's words like this bullying our Imperial College?"

Cai Lun did inherit his family tradition and was still very scheming. He deliberately led the conflict to the Taixue and the Imperial College. The Supervisor and the Taixue students were enemies. After Cai Lun said this, a Supervisor immediately said: "These rural woodcutters are worthy of competing with us? Mr. Cai, let's go. Talking to them is simply a disgrace to our identity."

Cheng Hui just smiled, looking very honest, and said carelessly: "In this way, the young men of the Imperial College are even worse than rural woodcutters. Alas, it is really worrying. If my officials from the Song Dynasty only know how to talk, it will be a declining place. No wonder the officials repeatedly mention the Imperial College and govern the country and the country will be safe in the future. Let us rural woodcutters come."

This sentence made the pain of the supervisor's foot, and Zhou Heng suddenly started to curse.

Cheng Hui smiled lazyly, ignored them, and said to his companions around him: "Come on the pen and ink."

Suddenly someone asked about the pen and ink. Cheng Hui smiled with a sigh, spread the paper on the ground, picked up the pen and started to write. His wrist moved lightly. After a moment, he stood up horizontally and looked at the paper that read: "The poems of Li and Du are passed down from thousands of words, but I still feel that they are not new."

Cheng Hui smiled at Xu Wei and said, "Brother Xu is itchy? You will make up for the second half of the quilt."

Xu Wei laughed: "It's great." He took the pen, squatted to take the next sentence, and it was completed in a moment. He picked up the pen and said: "There are talents in the country and the country have emerged, and they have been leading the way for hundreds of years."

As he said that, the two men took a group of tyrants away, and Xu Wei left a sentence and said, "I would like to ask Mr. Cai and all the supervisors for advice."

Cai Lun picked up the paper on the ground and his face was a little pale. This poem was not profound, but it was better than fluent. He could write such a happy poem in a short time, which shows how high the literary talent of these two people was. Then he thought, if it was me who wrote it, could it be written in such a short time? As he thought about it, cold sweat came out. It seemed that it was really difficult for students to deal with.

When I looked at the calligraphy of the two, they were both of them at the top. You should know that Cai Lun's great-grandfather was a master of calligraphy. He was very good at running script, but when he saw the running script of these two, he felt a little discouraged. He thought to himself: "The four talents of the Imperial Academy, Cheng, Zhu, Deng Xu, are indeed amazing."

At this time, Cai Lun's wandering nature was greatly reduced, and he could not raise his energy. He said boredly: "I'm back to school, you can do it yourself." After reading this poem, the other students were ashamed and ashamed, and said, "It's better to go back to study. The first exam is coming. You can't let the Taixue ride on our heads."

Zhou Heng pulled Chen Ao and said quietly: "Cousin, it seems that this first trial is not optimistic. I am afraid my holiday will be gone."

Chen Ao smiled and thought to himself: "It seems that the opponents I met today are very powerful. It's so powerful. Okay, find an opportunity to compete with them. But Cai Lun also needs to be careful of the dikes. This person is definitely not a good person."
