"It's really too slow."

Tang Ze used to rely on this to eat in his last life, and he still knew how to do it, and since he was asking for others, Tang Ze didn't mind giving him a slap: "The most annoying thing about oil painting is that the speed of painting is too slow."

Not to mention the technical scrutiny, just paint on the cloth, and the surface won't dry in two or three weeks.

And sometimes it is necessary to paint the next step on it, and the next step cannot be painted without doing it, so this is also a disadvantage of oil painting.

"Yes, it's just too slow."

Professor Shan Tian sighed and said, "I took over this project arrogantly back then, and did various researches, trying to add various propylene polymers to it, in order to develop a quick-drying pigment.

But unfortunately, it turned out to be nothing, and then we studied some carbonated polymers and solvents..."

Conan, who felt that the topic was running further and further away, felt that it was necessary to pull back the topic, so he expressed his "naive" curiosity by relying on his identity as a primary school student:

"Wait, Professor Grandpa, does this have anything to do with the paint we're looking for?"

"Pigment? Of course it has something to do with it." After being interrupted, Professor Shan Dian gave Conan a somewhat unpleasant look, and then said a somewhat "malicious" topic towards elementary school students: "You all know how the little blue chip was invented, right?

It was first discovered during clinical testing as a new drug for heart disease.

But the therapeutic effect that people had expected was very weak and close to none, but the side effects... I think you both should understand except this little boy. "

Speaking of this, Professor Shantian did not continue to speak. After all, there is a girl like Makase Kurisu here.

He just glanced at Conan who had interrupted him with slight contempt, and the disdain in his eyes seemed to say, "Little devil, you don't understand what I said?"

This act of "holding revenge" made Conan's mouth twitch involuntarily. As a high school student, he has already entered the "realm of adults". They still understand the knowledge, so he also understands what Xiao Lan Pian is.

But Professor Shandian's competitive behavior made Conan feel that this old man is really naive, and he should not compete with him... Otherwise, he always feels like it will be very troublesome...

So in the face of Professor Shan Dian's "provocation", Conan chose to play stupid and showed a dazed look.

And this expression fell into Professor Shantian's eyes, which made him feel the suppression of the "upper chain", and raised his eyebrows to "tactically lean back" against the sofa:

"It was this case that inspired me, what would happen if an 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 volatilization of the ester solution allows the oil paint to be air-dried quickly, and its surface adhesion is as high as 98%, everything is so perfect…”

Originally, we were ecstatic, because once this material was successfully invented, it would be transformative for the oil painting industry!

Even we had already registered the patent at that time, ready to participate in the national-level awards to appear in the world. "

And there is usually a "but" behind such words, and Professor Shan Dian sighed without exception: "But after half a month, "heaven" became "hell", and we found that all the paint started Rapid aging and cracking at a speed visible to the naked eye.

The experiment failed without exception, after all, who would want such a paint that would dry out a painting. "

"What about after that?" Tang Ze's expression brightened, knowing that he had grasped the key: "What happened after that?"

"What else is there after."

Professor Shan Dian waved his hand boredly, "That is, like many failed experiments, the project was suspended, and the data was sealed in the database for ashes."

"Professor Shandian wonders if he can show us this information?"

Seeing that the old man, who may have expressed his desires because of his loneliness, finally finished speaking the important information, Tang Ze immediately interrupted his thoughts of continuing to speak, and began to plead.

"No problem, come with me." Professor Shandian nodded his head still, then got up and brought everyone to the reference room.

But when the professor found the filing cabinet where the data was stored according to the document number recorded in the data, the research data that should have been stored there was already empty.

There were only stacks of white paper in the portfolio, and the experimental data that had been recorded had disappeared for a long time.

"Looks like we've found the right place."

Tang Ze looked at the blank piece of paper, put on white gloves, picked up a piece of paper that activated his super-smell, and then looked at Professor Shandian and said, "I don't know who ordered this research result back then? Professor, please remember it. "

"It's not necessary. We have records here. I'll look for it." Seeing that the data was lost, Professor Shantian seemed to realize the seriousness of the matter, and trotted out of the storage room with a staggering pace. .

After a while, he took back a document and handed it to Tang Ze.

After opening it and taking a picture with his mobile phone, Tang Ze returned the notebook to Professor Shandian: "Thank you, sorry for disturbing you, then leave the rest to me, and I will investigate the matter clearly."

After saying goodbye to Professor Shan Tian, ​​the group left the institute and walked out of the gate, Makase Honglixi smiled and said goodbye to Tang Ze: "Since we have found important clues~lightnovelpub.net~ I can't help the rest. If you're busy, go first."

"Thank you, Miss Muze." Tang Ze thanked: "It's been a great help."

"You're welcome, didn't Tang Ze help us before, it's just a matter of courtesy."

Makase Kurisu smiled and said, "And being able to maintain a good relationship with a reliable criminal like you, Tang Ze, is quite reassuring."

"If you need help, feel free to contact me, and I will try my best to help." Tang Ze naturally understood the meaning of Makase Kurisu's words, and made a promise with a smile.

Dealing with smart people is like this, and a good relationship can be established very quickly.

As for the reason for the other party to befriend Tang Ze, it may be that the previous case made Makase Kurisu feel that it is more reassuring to have a criminal acquaintance just in case, or it may be simply to expand her network.

But in any case, everyone likes things that benefit both parties.

Watching Makase Kurisu drive away, Conan got in the car and was about to say something when the phone rang.
