After all, he is still young and acting on impulse. Yang Lao shook his head secretly, but he thought it was a good thing that Wang Guan suffered a little loss. After all, he had learned a lesson and would not make the same mistake again in the future.

"Wang Guan, you finally made a mistake."

As they became more familiar with each other, Yu Feibai did not open his mouth to comfort him. Instead, he sprinkled salt on Wang Guan's wounds and said with a smile: "This is a normal thing. Otherwise, if I see you picking up the slack every day, I would doubt you."

Are you from Earth?"

Yang Lao and Yu Feibai, you and I rejected Wang Guan's judgment, but he didn't mean to be angry. He still had a smile on his face and picked up the ink bamboo painting to look at it carefully.

When the two people nearby saw this, they inevitably began to murmur in their hearts. Could it be that Wang Guan couldn't bear the blow and was losing his mind?

"Wang Guan, don't take it too seriously."

At this time, Yu Feibai stopped his smile and quickly advised: "Look at me, I often get punched in the eyes, and I also pay tuition fees..."

"I'm fine, I don't need you to comfort me." Wang Guan smiled and shook his head, and suddenly asked: "Fei Bai, do you still remember the blinding picture that Mr. Qian mentioned some time ago?"

"A leaf blinds one's eyes, and one cannot see Mount Tai." Yu Feibai was stunned, his eyes suddenly widened, and he exclaimed in shock: "Wang Guan, don't tell me, this is another thing covered up with a blind trick."

"It's hard to say." Wang Guan chuckled and said, "Don't you think the paper of this painting is a bit thick?"

"How thick is the paper?"

Yu Feibai quickly touched the ink bamboo pattern with his hand, rubbed it carefully, but shook his head blankly and said: "I don't know how thick it is. I have also seen Qi Baishi's original painting, which was made of seventeen or eight layers of rice paper."

"Good rice paper is made in layers. An ordinary piece of rice paper can be split into two or three layers, while high-quality rice paper can even be split into dozens of layers. That's why there are people who steal other people's calligraphy and paintings.

"

Wang Guan said with a smile: "However, I remember that the use of rice paper for painting became popular, which should be after the Yuan and Ming Dynasties. But in the Song Dynasty, the paper used for calligraphy and painting was usually cotton paper or hemp paper. Of course, there were other

Variety. However, there shouldn’t be much difference in thickness.”

"Not necessarily." Mr. Yang shook his head and said: "The use of paper in ancient times was different in each place. For example, during the Northern Song Dynasty, the most respected paper was the Chengxintang paper of the Southern Tang Dynasty. The Southern Tang Dynasty

After it was destroyed by the Northern Song Dynasty, this kind of Chengxintang paper became an exclusive item for the Northern Song Dynasty court."

"we know."

Yu Feibai said with a strange smile: "During the Chunhua reign of Emperor Taizong of the Song Dynasty, the Chunhua pavilion calligraphy collection that brought together calligraphy and ink from various schools was made using this kind of Chengxintang paper and Li Tinggui's ink copy."

"Brother is right."

Yang Lao laughed and said: "However, after the fall of the Southern Tang Dynasty, the technology of Chengxintang paper seemed to have been lost, resulting in less and less of this kind of paper. By the middle of the Northern Song Dynasty, Chengxintang paper was already very precious, and was worth a lot of money.

It’s hard to find. For example, famous people like Cai Xiang, Ouyang Xiu, Mei Yaochen, etc., who got a few pieces of Chengxintang paper, were very happy to post their poems as a souvenir."

"By the time Su Dongpo arrived, that kind of Chengxintang paper had basically disappeared."

Mr. Yang pondered and said: "It seems that there was a man named Pan Gu at that time who was not only good at making ink, but also knew how to make paper. He imitated Li Tinggui ink and Cheng Xintang paper in the Southern Tang Dynasty and developed a new ink and new paper.

He was favored by Su Dongpo. After Pan Gu died, Su Dongpo wrote poems to commemorate him."

"So, the ancient literati did not despise technology as much as we imagined." Mr. Yang smiled and said: "At least, not only scholar-bureaucrats valued scholar-bureaucrats, but even the emperor liked them very much. However, due to frequent wars,

, most of the technology has been lost. So we people today feel that the ancients despised technology and regarded it as a strange skill!"

As the inheritor of ancient handicrafts, Mr. Yang has a better say in this aspect. However, he also realized that what he said seemed to be a little off-center. He quickly pulled it back and said with an embarrassed smile: "I want to say that every place

The technology is different, so the paper produced is also different in thickness."

"Wang Guan, do you want to say that a thin layer of paper was applied to this picture to cover up the important features of Wen Tong's ink bamboo picture?" At this time, Yu Feibai somewhat understood what Wang Guan meant.

, hesitantly said: "This possibility is not impossible. However, the possibility is very low. However, if you want to verify it, you can find an expert to help you uncover it."

"If you're not sure, it's best not to try."

Mr. Yang obviously didn't believe in any kind of deception, so he kindly advised: "You know, it takes a lot of skill to peel off the frame. If you are not careful, the whole painting will be ruined."

Yu Feibai also nodded in agreement and said: "Mr. Qian once told me that unless the calligraphy and painting are in such tatters as butterflies are dancing, you should never unmount them. If you must unmount them, you must also hire experienced craftsmen.

Otherwise, if you meet someone with poor skills, you will become an executioner."

"I see."

Wang Guan nodded and found that the two of them were still worried, so he simply said: "I'm 100% sure."

"What's 100% sure?" Yu Feibai shook his head and sighed: "Don't forget Uncle De's instructions. He also asked you to monitor me and not to mess around. Who knows, you will get even more intolerable."

"This is different. I want the original work to be seen again, not to destroy the painting." Wang Guan said with a helpless smile: "If you don't believe it, I can do a small verification."

"How to verify?"

Yu Feibai and Mr. Yang were both very curious.

Wang Guan pointed to the lower left side of the ink bamboo painting and said with a smile: "According to the general drawing layout, after the painting is completed, the author's name or seal will be stamped here."

In fact, Wang Guan had already understood it through his special ability. While speaking, he dipped his finger into a drop of water and gently pressed the drop on the blank area of ​​the ink bamboo picture.

In an instant, the water droplets penetrated into the paper and spread in all directions.

At the same time, a reddish vermilion seal appeared on one side. The writing on the seal was blurry, but the four characters Wen Tong and Ke could barely be recognized clearly.

"No!"

Yu Feibai was shocked, dumbfounded, and completely stunned.

Mr. Yang next to him was in a similar situation. His cloudy eyes were fixedly looking at the seal, full of disbelief.

After a while, Yu Feibai came to his senses first, looked at Wang Guan with complicated eyes, smiled bitterly, and sighed: "You kid, you picked another big mistake. I'm numb now, I don't know if I should congratulate you,

I should beat you up out of jealousy. By the way, with this thin layer of paper covering it, how can you be so sure that this painting is the original work of Wen Tong?"

"Haha..." Wang Guan laughed dryly and suddenly realized that this question was difficult to explain.

Just when Wang Guan was thinking about a reasonable excuse, Mr. Yang stood up, grabbed him, and said urgently: "Brother, let's go!"
