"It's really too slow."
Tang Ze made a living from this in his previous life, so he was quite knowledgeable. And since he was asking for help, Tang Ze didn't mind giving him a little pat on the back: "The most annoying thing about oil painting is that it's so slow."
Not to mention the repeated review of techniques, just applying paint on the cloth would take at least two or three weeks for the surface to dry.
Sometimes you need to paint the next step on it, and you can't paint the next step if it's not dry, so this is also a disadvantage of oil painting.
"Yes, it's just too slow."
Professor Shan Dian sighed, "Back then, I took on this project with arrogance and did all sorts of research, trying to add various acrylic polymers in order to develop a quick-drying pigment.
Unfortunately, we found nothing, so we then looked into some carbonate polymers and solvents..."
Conan felt that the topic was going off track, so he felt the need to bring it back to the topic. He relied on his elementary school student status to express his "naive" curiosity:
"Wait, Professor, does this have anything to do with the pigment we're looking for?"
"Pigment? Of course it's related." After being interrupted, Professor Yamadan looked at Conan with some displeasure, and then said a topic that was a bit "malicious" to elementary school students: "You all know how the little blue tablets were invented, right?
It was originally discovered during clinical testing as a new drug to treat heart disease.
But the therapeutic effect that people originally hoped for was very weak and almost non-existent, and the side effects... I think you two should understand it except for this little boy."
Having said this, Professor Yamadan stopped talking. After all, there was a girl named Makise Kurisu here, and it would be difficult to speak so bluntly, otherwise it would seem disrespectful.
He simply glanced at Conan, who had interrupted him earlier, with a look of slight disdain, the disdain in his eyes as if to say, "Kid, you don't understand what I'm saying, do you?"
This "vindictive" behavior made Conan's mouth twitch. As a high school student, he had already begun to step into the "adult realm" and they still understood those knowledge, so he also knew what the little blue piece was.
But Professor Yamadan's aggressive behavior made Conan feel that this old man was really childish. It would be better for him not to compete with him... Otherwise, it would always feel very troublesome...
So in the face of Professor Yamadan's "provocation", Conan chose to play dumb and looked confused.
Professor Shandian's expression made him feel the pressure of the "Upper Chain". He raised his eyebrows and leaned back on the sofa.
"It was this case that gave me inspiration. What effect would it produce if acrylic ester solution was added to oil paint?
So in this direction, we spent a lot of time and energy, constantly experimenting and inventing a new oil paint.
Unique.
The evaporation of the ester solution allows the oil paint to dry quickly, while its surface adhesion is as high as 98%. Everything is so perfect..."
We were originally ecstatic because once this material was invented, it would be revolutionary for the oil painting world!
We had even registered a patent and were preparing to enter a national award and present it to the world.”
Such statements are usually followed by a "but," and Professor Shan Dian sighed without exception: "But half a month later, 'paradise' turned into 'hell,' as we discovered that all the paint began to age and crack at a speed visible to the naked eye.
The experiments all failed, because who wants paint that will dry out and crack?
"What happened next?" Tang Ze's expression brightened, knowing he had grasped the key point. "What happened next?"
"There's nothing after that."
Professor Shandian waved his hand in boredom. "It's just like so many failed experiments. The project was terminated and the data was sealed in the database, gathering dust."
"Professor Shandian, could you take us to look at this information?"
Seeing that the old man, who might have a strong desire to express himself due to loneliness, had finally finished telling the important information, Tang Ze immediately interrupted his idea of continuing to speak and began to make a request.
"No problem, come with me." Professor Shandian nodded with a lingering feeling, then stood up and led everyone to the information room.
But when the professor found the filing cabinet where the materials were stored according to the document number recorded on it, the research materials that were supposed to be stored there were already empty.
There were only stacks of white papers in the file bag, and the experimental data that had been recorded had disappeared long ago.
"Looks like we've found the right place."
Tang Ze looked at the blank paper, put on white gloves, picked up a piece, activated his super sense of smell, and sniffed it. Then he looked at Professor Shandian and said, "I wonder who ordered this research result back then? Please remember it."
"That's not necessary. We have the records here. I'll go find them right away." Seeing that the information was lost, Professor Shandian seemed to realize the seriousness of the matter and trotted out of the storage room with staggering steps.
After a while, he brought back a document and handed it to Tang Ze.
After flipping through it and taking a photo with his phone, Tang Ze returned the notebook to Professor Shandian: "Thank you for bothering me. Leave the rest to me. I will investigate the matter thoroughly."
After bidding farewell to Professor Yamadan, the group left the institute. Makise Kurisu smiled and said goodbye to Karasawa, "Now that we've found an important clue, I can't help you with anything else. I'll be leaving now."
"Thank you, Ms. Makise." Tang Ze thanked her, "You've been a great help."
"You're welcome. Didn't Detective Tang Ze help us before? It's just a courtesy."
Makise Kurisu smiled and said, "Besides, being able to maintain a good relationship with a reliable detective like you, Karasawa, really gives me peace of mind."
"If you need help, feel free to contact me. I will do my best to help." Tang Ze naturally understood what Makise Kurisu meant and made a promise with a smile.
This is how you deal with smart people. By exchanging gifts, you can quickly establish good interpersonal relationships.
As for the reason why the other party is befriending Tang Ze, it may be that the previous case made Makise Kurisu feel that it would be more reassuring to have an acquaintance in the criminal field just in case, or it may be that she simply wants to expand her network.
But no matter what, everyone likes things that are mutually beneficial.
Watching Makise Kurisu drive away, Conan got in the car and was about to say something when his phone rang.
