"It's just that it was done too slowly."
¡°After all, Tang Ze had relied on this to make a living in his last life, and he was still knowledgeable. And since he was asking for help, Tang Ze didn¡¯t mind giving him a compliment: ¡°The most annoying thing about oil painting is that the painting speed is too slow.¡±
??????????????????????????????????????????????????????? out of just applying paint on the cloth, the surface will not be dry until two or three weeks.
Sometimes it is necessary to paint the next step on top, and the next step cannot be painted until it is dry, so this can be regarded as a shortcoming of oil painting.
¡°That¡¯s right, it¡¯s just that it was done too slowly.¡±
Professor Shantian sighed: "Back then, I proudly took over this project, did various researches, and tried adding various propylene polymers to it, in order to develop a quick-drying pigment.
"But unfortunately, we found nothing, and then we studied some carbonic acid polymers and solvents"
Feeling that the topic was going further and further, Conan felt it was necessary to bring it back, so he expressed his "innocent" curiosity based on his identity as a primary school student:
"Wait, Grandpa Professor, does this have anything to do with the paint we are looking for?"
"Pigments? Of course it does matter." After being interrupted, Professor Shantian glanced at Conan somewhat unhappily, and then said a topic that was somewhat "malicious" to primary school students: "You all know how the little blue film was invented, right?
It was originally discovered during clinical testing as a new drug to treat heart disease.
But the therapeutic effect that people originally expected was very weak and almost non-existent, but the side effects I think you two should understand it except this little boy. "
Speaking of this, Professor Shanden did not continue. After all, there is a girl named Makise Kurisu here, so it is difficult to speak so straightforwardly or it will appear old and disrespectful.
He just glanced at Conan who interrupted him with a slight look of disdain, the disdain in his eyes seemed to say: "Kid, you don't understand what I said, do you?"
This act of "holding a grudge" made Conan's mouth twitch. As a high school student, he has already entered the "adult realm". They still understand the knowledge, so he also understands what the little blue film is.
But Professor Shantian¡¯s competitive behavior made Conan feel that this old man is really childish, and it¡¯s better not to compete with him Otherwise, it will always feel like it will be very troublesome
So in the face of Professor Shantian's "provocation", Conan chose to play dumb and showed a dazed look.
And when this expression fell into the eyes of Professor Shandian, he felt the suppression of the "superior chain", and he raised his eyebrows and activated "tactical leaning back" to lean on the sofa:
¡°It was this case that inspired me. What would be the effect 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 brand new oil paint.
The volatilization of the ester solution allows the oil paint to be dried quickly, and its surface adhesion is as high as 98%. Everything is so perfect"
Originally, we were overjoyed, because once this material is successfully invented, it will be revolutionary for the oil painting industry!
We had even registered a patent at that time and were preparing to participate in national-level awards to appear in the world. "
There is usually a "but" behind such words, and Professor Shandian sighed without exception: "But after half a month, "heaven" turned into "hell", and we found that all the paint began to It ages and cracks rapidly at a speed visible to the naked eye.
The experiments failed without exception. After all, who would want this kind of paint that would make the paintings dry and crack? "
"What happened after that?" Tang Ze's expression brightened and he knew he had grasped the key: "What happened after that?"
¡°There is nothing else to come after.¡±
Professor Shantian waved his hand boredly, "That is to say, like many failed experiments, the project was suspended and the data was sealed in the database to gather dust."
"Professor Shantian is wondering if he can take us to see this information?"
Seeing that this old man, who may have a desire to express himself because of his loneliness, finally finished telling the important information, Tangze immediately interrupted his thoughts of continuing to tell and began to plead.
"No problem, come with me." Professor Shandian nodded, and then stood up and led everyone to the data room.
It can be used as a professor to find the file where the data is stored based on the document number recorded in the data.At that time, the research data that should have been stored there were already empty.
There are only stacks of white paper in the file bag, and the experimental data that was once recorded disappeared long ago.
"It seems we have found the right place."
Tangze looked at the blank paper, put on white gloves, picked up one and activated his super-smell sense and smelled it. Then he looked at Professor Shantian and said, "I wonder who ordered this research result back then? Please remember it, Professor." "
"That's not necessary. We have records here. I'll go look for them right now." Seeing that the data was missing, Professor Shanhao 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 piece of information and handed it to Tang Ze.
After opening it and flipping it through, Tang Ze returned the record book to Professor Shandian after taking pictures with his mobile phone: "Thank you, excuse me, then leave the rest to me. I will investigate the matter clearly."
After bidding farewell to Professor Shanden, the group left the research institute and walked out of the gate. Makise Kurisu smiled and said goodbye to Karasawa: "Now that we have found important clues, I can't help with the rest, so let's start with gone."
"Thank you, Miss Makise." Tangze thanked, "It's been a big help."
"You're welcome. Didn't Tang Ze Criminal also help us before? It's just a courtesy."
Makise Kurisu smiled and said: "And being able to maintain a good relationship with a reliable criminal like you, Karasawa, is very reassuring."
"If you need help, please contact me at any time. I will do my best to help if I can." Tangze naturally understood the meaning of Makise Kurisu's words and made a promise with a smile.
This is how you deal with smart people. You can quickly establish good relationships through courtesy.
As for the reason why the other party made friends with Karasawa, it may be that the previous cases made Makise Kurisu feel that it would be more reassuring to have a criminal acquaintance just in case, or it may just be to expand her network of contacts.
But no matter what, everyone likes things that benefit both sides.
Watching Makise Kurisu drive away, Conan got in the car and was about to say something when the phone on his body rang. (Remember the website address: www.hlnovel.com
