"arrive."

Wang Guan and others got off the car one by one, looked at Professor Liu's house casually, and then, under his inviting, slowly walked into the building and came to the living room on the second floor.

Compared with Mr. Jin's house, Professor Liu's home decoration is obviously more tasteful. The snow-white walls are hung with several calligraphy and painting works, coupled with elegant wooden furniture, and the evergreen trees placed in the corners have a somewhat elegant and ancient atmosphere.

"Everyone is welcome to come and be guests."

At this time, Professor Liu smiled and said, "Sit as you like, don't be restricted."

After a few minutes of busy work, I poured a cup of tea for each person before I stopped. However, Qin Yue did not forget the purpose of coming here. She took a sip of the tea soup casually and immediately said straight to the point: "Professor Liu, is the recipe for phoenix glue you mentioned true or false?"

"What, I'm still suspicious." Professor Liu chuckled and said, "You can give it to you for verification, but..."

"But what."

Yu Feibai simply asked: "What are your conditions? Or how much does it cost, you can directly report the number."

"It's too vulgar to talk about money if you don't talk about money." Professor Liu waved his hand and smiled: "It's actually not a condition, it's just a proposal."

"Don't keep it a secret." Yu Feibai curled his lips and said, "If you have any suggestions, we can consider it."

That's right, it's just a consideration. On the way here, they had already discussed it and could not be too eager. Otherwise, Professor Liu might be fearless and want to make a big splash.

"It's just a small proposal."

At the same time, Professor Liu suddenly changed his mind: "By the way, I didn't tell you. Actually, I am studying botany and I am very interested in plants. Not only the roots, branches, stems, leaves of plants, but also the rubber of plants..."

"The fox's tail is finally revealed."

At this moment, Wang Guan and others looked at each other, their faces full of clarity. It seemed that their judgment was correct, and Professor Liu's goal was indeed the thing in the box.

"A wise man doesn't say secret words."

It would be much easier to determine Professor Liu's goal. Yu Feibai smiled. His attitude also eased, his tone was no longer stiff. On the contrary, he felt a little bit like a spring breeze: "We understand what Professor Liu meant, do we want this box, right?"

Professor Liu smiled without saying a word, but asked, "Actually, Luan Gummy. To put it bluntly, it is an animal glue. Its adhesion may not be stronger than modern chemical glue. I wonder what you are going to do?"

Everyone is smart, so of course I understand Professor Liu’s rhetorical questioning is not only curious, but also a tactful rebuttal.

Just as Wang Guan and others could not tell Professor Liu why they needed rubber, Professor Liu could not tell them the background of the material in the box. To put it bluntly, it was still a matter of trust. If they did not trust each other, they would naturally test each other.

"Okay, since the skylight has been opened, there is no need to cover it up." At this time, Wang Guan said, "In fact, we don't have to know what this box of things is and what value it has."

"Yes, our purpose is very clear. It is to ask for Luan Gummy or Luan Gummy recipe." Yu Feibai echoed: "You said there is Luan Gummy recipe. Then you give us the recipe and we give you this thing. How about fair trade?"

"Yes." Professor Liu smiled and said, "Actually, this is the suggestion I want to say."

"Of course, the premise of everything is that the formula is useful, it is a real rubber formula..."

However, Wang Guan was very cautious: "Professor Liu, it's not that we don't believe you. Instead, the things in the box are placed here, visible and touched, without any false moisture. But the formula is not easy to distinguish the authenticity."

"That's right." Yu Feibai Shen agreed: "You said yes, we believe it now, but after looking back, you can't make luan glue according to the formula, that would be a big loss. If you once made the real thing by yourself according to the formula, that's different."

"I only have the formula, but I have never refined Luan Gummy. Otherwise, I will give you the real thing directly. But since I am sure it is the Luan Gummy formula, I must be sure." Professor Liu said seriously: "And I also need to declare in advance that the formula is right, but whether it can be refined Luan Gummy according to the formula is your own business, and I will not be responsible."

"What's the meaning?"

In an instant, Wang Guan and others frowned, their eyes full of doubts. Why do these words sound like a fooling person's rhythm?

"Don't think I'm lying."

Professor Liu shook his head gently and said calmly: "Have you ever seen the recipe for alchemy for ancient Taoist priests?"

"Taoist priest's alchemy recipe?"

At this time, Wang Guan vaguely understood: "What do you mean is that the formula of Luan Gua is written in cryptic words?"

As we all know, in order to pretend to be a ghost and to prevent leaks of secrets, the ancient Taoist priests wrote very obscurely, whether it was the "secret recipe" of cultivation or the recipe for refining magical pills. They were used to use some secret words to express something, and other people did not understand the meaning of it except himself and his peers and disciples.

The most typical example is the talismans drawn by Taoist priests, a bunch of messy symbols. Ordinary people don’t know what they mean, so they can only be called ghost painting talismans.

If the formula of Luan Gummy is the same, then it is not impossible. After all, Luan Gummy has a very close relationship with the gods and alchemists, so it seems natural to write in hidden words.

"This guy is smart, you guessed it right."

Professor Liu was very happy and praised him with a thumbs up: "The ancient formula cannot be as detailed as modern secret recipes, and even the process is marked. All ancient formulas have a bit of a big deal, and they need to be explored by themselves to master them. The same is true for Luangu. Only the materials are marked, and then it is simply mentioned that it needs to be steamed, boiled and dried before it can be finally formed."

"But these materials really have very abstract names such as kirin horns and phoenix beaks."

While speaking, Professor Liu said frankly: "You need to study the specific things of these names yourself. This is the situation. You still want to exchange them. I can get the recipe immediately. If I don't agree, I can't do anything, but I want to ask more. Can the things in the box be sold to me?"

That's it, but Professor Liu could predict that Wang Guan and the others would definitely agree to the exchange. After all, when they tested each other, they had already grasped their psychological bottom line. It was clear that they valued the phoenix glue formula that Professor Liu decided to tell the truth. Moreover, this matter could not be hidden, and being honest can leave a good impression on each other.

"Qin Yue, what do you think?"

Wang Guan turned around and asked, knowing that he was doing nothing.

Sure enough, Qin Yue nodded without hesitation: "Switch!"

"Since that's the case, you'll take a moment." Professor Liu smiled and immediately stood up and walked out.

"Take the original recipe, don't fool us with re-copy..." Yu Feibai reminded him loudly, but he was still not very worried about Professor Liu's character.

"Know."

Professor Liu nodded and left, and came back soon after. Then he put the things in his hand on the table. Wang Guan and others quickly looked at it and saw that the thing was a square box and a page of paper with words written on it.

Of course, this paper is not a contract, but a half-piece recipe.

Professor Liu is not stupid either. It is impossible to make all the recipes public, otherwise Wang Guan and others would write them down. What should I do if I don’t exchange them with him? So I wrote half of the recipe for them to show them, but the whole recipe was engraved in the box.

"This box is an antique from the Han Dynasty."

At this time, Professor Liu explained: "A few years ago, I moved my ancestral home and accidentally found this thing in the corner. I thought the box was quite exquisite, so I took it back. When I returned home to watch it, I found words engraved in the wall of the box. After research and investigation, I confirmed that this was the recipe of Luangu."

"The things look really good. Could it be the container that used to hold Jiaoluan back then?"

Yu Feibai's speculation was approved by Wang Guan. After a closer look, the box was made of brass, rectangular, but without edges. On the surface of the box, it was decorated with cranes and auspicious clouds, which was very consistent with the ancients' fantasy of gods. To a certain extent, using such a delicate copper box to hold rubber does not seem to be a loss of price.

No matter what, researching formulas is the main thing.

Now everyone's eyes fell on the paper, and they saw a few lines of words written on the paper, not only unreliable materials such as the horns of the kirin and the phoenix beak, but also some ingredients, some ingredients for oily and gelatinous plants.

"This is two-thirds of the material." Professor Liu said bluntly: "Although there are several more critical materials and the methods of processing and refining, you should understand that I am not lying."

"Qin Yue."

Wang Guan pondered for a while and asked hesitantly: "What do you think?"

"It should be true."

Qin Yue nodded slightly, and her pretty eyes shone with waves of surprises. She worked hard and lived up to the world. After searching for it for several years, she finally got rewards. The excitement in her heart was hard to express. Now she did not cheer and jumped out, which proved that she was calm and generous enough.

"So that's the case."

In an instant, Wang Guan crossed his hands, wronged the two boxes on the table, and then smiled and said, "Professor Liu, we have completed the deal, do you need to write a transfer agreement or something?"

"Haha, there's no need to be so troublesome." Professor Liu also showed a happy smile on his face: "Although we are only meeting for the first time, I also know that some of them will not go back on their word and ruin their promises..."

"Of course."

Yu Feibai nodded proudly, but after seeing the excitement in Professor Liu's eyes, he finally couldn't help asking: "The thing is already yours. You can tell us now, right? Even if it is resin, what kind of tree's resin, what is the specific function, there should be no need to keep it confidential, right?"

"That's it."

At this time, Professor Liu hesitated and thought for a while before smiling and said, "It's not that I don't want to say it, but I'm afraid you won't believe it."
