PS: In the middle of the month, if you have a ticket, please support it.

Yu Feibai's words touched Professor Liu, or he got a good thing, so he always wanted to express the joy in his heart. This is the norm, and no one can avoid it.

Professor Liu was no exception, under Yu Feibai's prodding, he first took the box in his hand, and then smiled happily: "Actually, I'm not lying, this is indeed resin." However, it is not a normal resin, but a gelatin called fluorescent tree. ”

"Fluorescent trees?"

Wang Guan and the others were stunned, and Yu Feibai shook his head and said, "I've never heard of it." ”

"It's normal not to have heard of it, because the plant is extinct."

Professor Liu said with a smile: "It was extinct as early as the middle of the Tang Dynasty, and now there are only records of this plant in some unpopular ancient books. Of course, the fluorescent tree is the name I gave according to its function, but in ancient books it is something else. ”

While speaking, Professor Liu mentioned several ancient names in a row, but Wang Guan and Yu Feibai still shook their heads again and again, ashamed of their loneliness.

"This is normal, they are all relatively out-of-the-way books, not specialized in research, and few people pay attention to them." Professor Liu comforted in turn: "Don't talk about this plant, even some university scholars may not know about it." It's normal to have a specialization in the art industry. ”

Yu Feibai nodded, and then continued to ask for advice: "Then what is the effect of such vegetable gum grease?" ”

"This plant prefers to grow in areas rich in phosphorus soil, and although it is a tree, the adult plant is only a foot tall. Because the root system is very well developed and can absorb a large amount of phosphorus powder, at night, the branches and leaves of the plant can fluoresce under the reflection of the moonlight. ”

Now that he has said it, Professor Liu no longer hides it: "Not only the branches and leaves, but also the branches and leaves, rhizomes, and resin are refined." It also has such a function, and it can emit a faint fluorescence at night. ”

After prompting the mystery of the substances in the box, Professor Liu couldn't help but hold the box tightly, not because he was worried that Wang Guan and others would regret it, but because it was just an instinct. In addition, I think that at this time, they should be dumbfounded and amazed. However, Professor Liu looked and found that these people reacted very coldly, without any emotional fluctuations.

For a moment, Professor Liu felt unbalanced in his heart, and said very strangely: "This is a very rare thing. Or do you not believe what I say? ”

"Believe, how not to believe."

Yu Feibai shrugged his shoulders and said casually: "Although things are rare, to put it bluntly, they are just variants of the Night Pearl. Such a thing may have been worth a lot of money in ancient times, but it is not worth much now. ”

"That's because you don't know the true value of this thing."

At the right time, Professor Liu was a little annoyed, after all, he regarded it as a treasure, but others regarded it as a cabbage on the rotten street. Of course, it makes people feel uncomfortable. On the spur of the moment, Professor Liu directly told the real mystery of things: "According to ancient records, some people melted this glue into ink, and then drew pictures in the book. Works can also shine at night......"

"What."

In an instant, Wang Guan and the others were naturally startled, somewhat suspicious.

"Really?" General Yu Feibai was suspicious: "I don't seem to have heard of such calligraphy and painting works." ”

"Didn't I tell you that this plant was very rare in ancient times. And it became extinct in the middle of the Tang Dynasty. Professor Liu argued: "If you think about it, there are not many Tang paintings that have been handed down to the present. What's more, calligraphy and painting with this kind of glue are even rarer, and they are hard to find. ”

"You sound right."

Yu Feibai nodded, shook his head again, and said, "But I still don't believe it, unless I ...... Professor Liu, it's not that I'm suspicious, maybe there was such a thing in ancient times, can you really be sure that the glue in this box is what you call fluorescent resin? So I think you'd better verify it, so as not to have a lot of joy. ”

"Declare in advance, if it is not fluorescent resin, we are not responsible." Yu Feibai's last sentence can be described as hitting the nail on the head, which naturally made Professor Liu a little shaken.

"It's here anyway."

At this time, Wang Guan added fuel to the fire: "Whether it's true or not, just take a little bit and do an experiment." Of course, if Professor Liu thinks it is true and is willing to take it seriously, then let's wait until we have said nothing. ”

"That's that......"

Yu Feibai cooperated tacitly, and also showed a different smile, as if he was laughing at Professor Liu and preparing to deceive himself.

Under such circumstances, how could Professor Liu still be calm, he immediately stood up without saying a word, and then stretched out his hand to invite: "Everyone, please come to my study to be a witness." ”

Wang Guan and the others would definitely not refuse, and happily followed Professor Liu to his study.

When they walked into the room, they realized that this was not so much Professor Liu's study as his collection room. In a space as spacious as a living room, there are not only desks, bookshelves and other study items, but also two or three rows of shelves. The shelves are full of all kinds of antique objects, and the Boshan furnace bought back at Uncle Jin's house is also among them.

In this way, Professor Liu's collection is relatively rich, and there are some small masterpieces among them.

Seeing that the hunting heart was happy, Wang Guan naturally looked at it. Although there is no hands-on touch appreciation, it is generally possible to determine which things are genuine, which things may be imitations, and of course there are fakes at a glance.

However, as a guest, even if a fake was found, Wang Guan had no intention of correcting it. After all, among the antique industry, it is the most taboo to talk deeply. If you don't have enough friendship, if you say something is fake, people may not believe it, or they may think that you want to trick him.

Why is it that connoisseurs always habitually use tactful language to describe fakes when they speak? The reason for this is nothing more than that it is already very sad to buy a fake thing, and if you don't pay attention to your tone, people will definitely think that you are gloating, rubbing salt on your wounds, and it is strange not to turn your face.

Therefore, even if Wang saw any clues, he would not talk casually, and at this time, Professor Liu was not in the mood to listen, and after entering the study, he immediately took out pen, ink, paper and inkstone, intending to verify his judgment.

The paper is the best rice paper, the pen is the lake pen in the south of the Yangtze River, the inkstone is the end of the inkstone, as for the ink, it is not simple, it is a special pine smoke ink ingot. Today's calligraphers and painters, unless they do not have this environmental condition, generally use high-end and high-grade ink ingots. Ink or something, it's a low-end thing, and it can't be on the table anymore.

The use of ink ingots, naturally not only retro fashion, vassal elegance, but also concentrated is the essence, the ink ground out with ink ingots, the ink color is like lacquer, the oil is shiny, and the quality is indeed better than the ink.

Of course, Professor Liu now uses ink ingots, and that is due to the need for blending. At this moment, he cut a small amount of so-called fluorescent grease from the box and put it in the inkstone, then dropped a few drops of water, and then picked up the hard ink ingot and grinded it.

In the uniform movement of the fingers, the glue has no signs of dissolving, but Professor Liu is also very patient, constantly grinding, grinding, and pressing, and the ink comes out a lot, but the glue is like kraft candy, and it has not melted for a long time.

Seeing this, Wang Guan and Yu Feibai looked at each other, their eyes full of suspicion.

According to Professor Liu, the grease should be able to melt in the ink, and then use this blended ink to write, so that the effect of fluorescence can be achieved at night.

However, it now seems that there is no sign of dispersion at all, which can prove that Professor Liu's inference is wrong.

Of course, Professor Liu couldn't die so quickly, and he was still working hard. Seeing this, Wang Guan shook his head slightly, walked away a few steps with some boredom, and continued to look at the collections on the shelves.

It can be seen that although Professor Liu's collections are a little messy, there is also a certain trend of special collections. Among the many items, there are many utensils such as the study room.

Among them, the pen holder, pen holder, pen hanging, pen wash, ruler, arm rest and other small objects are the main, the materials of these things are jade, bamboo, wood, tooth angle ceramics and so on, the shape is different, the carving is exquisite, can be used to appreciate, it is also good.

Of course, there are also large things, for example, Wang Guan saw a vase with a large belly, nearly fifty centimeters high, and the surface is decorated with colorful patterns. It looks very much like a colorful vase of the Qing Dynasty, but the painting skills are too poor, or there is no painting skills at all, but directly glued with applique paper, and a little look knows that it is a modern craft work.

However, Professor Liu should know the bottom of this pot-bellied vase, otherwise he would not have been put in the corner.

Wang Guan smiled, his eyes swept over the corner, and suddenly he saw something, and then he froze, his eyes looked straight at him, surprised, delighted, and incredulous, anyway, his mood was very complicated.

Others didn't pay attention to Wang Guan's abnormality, and they were still paying attention to Professor Liu's ink. Finding that the glue in the inkstone had not yet melted, Yu Feibai finally couldn't bear it anymore, and said euphemistically: "Professor Liu, after grinding for so long, you should be tired, do you want to rest?" ”

Professor Liu turned a deaf ear and continued to study the ink, and the full and shiny ink became more and more, but the glue was round or flat, forming a strange shape under the pressure of the ink ingot, but it did not melt.

In this case, Professor Liu was also a little irritable, and finally threw away the ink ingot. Because the action was too big, it even shook the inkstone, splashing a puff of ink and polluting a piece of snow-white rice paper on the table.

For a while, there was a bit of a mess on the table, and Professor Liu didn't mean to clean up, but picked up the soap and slowly cleaned his hands in the basin next to him. The expression on his face was serious, but it was difficult to hide the look of disappointment in his eyes.

"Professor Liu, you don't have to be sad."

At this time, Wang Guan woke up, looked back, and immediately understood what was going on. In the middle of his thoughts, he opened his mouth and comforted: "This thing is even fluorescent gum resin, but after thousands of years have passed, or some qualitative changes have occurred, it no longer has the original effect......

"That's right." Yu Feibai thought so, and sighed: "Time is a killing pig, the knife is bloody, no one can stop it, not to mention the glue and juice things, I'm afraid it has long been degraded and invalid." (To be continued......)
