Back in the lab, call the three of them together and ask about the progress of their respective tasks.

The two daughters were very smart, and found that photoresists, etchings, chips and circuit boards were similar in principle, so they checked the information together and studied together.

Yan Jiefang is lucky enough to be able to produce purple light with a mercury lamp, and is conducting experiments and research on intensity and stability.

Li Guocheng put forward new requirements for Yan Jiefang, on the premise of solving the current problem, consider generating parallel rays, and then use lens groups to reduce the area of violet light.

The second daughter's task progress is slow, and now she only understands the principle of film exposure. The composition of the film is also somewhat understood, but it is far from success.

After listening to their reports, arrange for them to continue their research and purchase relevant materials. Yan Jiefang went to the procurement department to apply for the purchase of lenses.

After the meeting, Li Guocheng also had no choice, his understanding of chemistry was still in the middle school curriculum, and a lot of knowledge was forgotten, so he had no choice but to re-study.

Came to the front of the chemistry books, began to read frantically, a week later, all the books were finished, and then in my mind continued to classify, combine and decompose, the understanding of chemistry is only the basic, how to prepare medicines, the knowledge is still insufficient.

Li Guocheng stayed in the library for another three days, commuting to and from work with the library normally, until he could no longer find the relevant materials, and then reluctantly returned home.

During the meal, Zhao Ting looked at Li Guocheng's distracted appearance and didn't know how to help.

"I don't know what you're going to do, but it feels like you're in a bit of a hurry right now. Take our work as an example, the way we think about our work is very different from the method taught to us by our master. The enemy is progressing, they are also changing their modus operandi, and we are constantly groping and improving in the struggle."

"Your progress has been very fast now, so many experts with the help of Big Brother, 20 years, in many fields are still in the imitation stage...

Li Guocheng suddenly interrupted Zhao Ting's words, "What did you say just now?" ”

"You're making rapid progress now."

"No, next sentence".

"That's a lot of experts with the help of Big Brother".

"Next sentence".

"Many fields are still in the imitation stage", Zhao Ting looked confused.

"Imitation, imitation, imitation ... , hahaha, I see".

Li Guocheng began to reflect, starting with the Dawning II machine tool, and the vacuum furnace, lifting method, cutting stage, grinding machine, multimeter, transistor, radio chip, and radio designed later were all based on his own later memories or mature methods in books.

All his inventions should be described as copies. Chip design is in its infancy all over the world, and there is no material to draw on, unless he visits a Western laboratory and uses telekinesis to steal it directly.

Now it is obviously impossible, so he can only invent it himself.

Li Guocheng didn't eat anymore and sat at the table in a daze. Zhao Ting was already commonplace, so she didn't bother him, and after eating silently with Aunt Liu, she left the table and left the space to Li Guocheng.

Li Guocheng is now combing through the knowledge in his mind and classifying all kinds of knowledge, as long as it is related to glue, resin, light sensitivity, discoloration, corrosion resistance, corrosion, dissolution, solution and other related knowledge, all of them are gathered together.

Then it is a matter of careful analysis, prioritization, and subsequent experimental verification.

The following month, Lab 1 became a chemistry lab.

For the safety of others, Li Guocheng set aside a small space in the laboratory to do chemical experiments, and a curtain was hung on the door.

From then on, from time to time there would be explosions in this small laboratory, or the light would be flickering, or there would be a foul smell。。。。。。

Now Li Guocheng is stunned again, because of his previous experience, and Li Guocheng will go home in 2 or 3 days, and everyone is not at a loss like last time.

It's just that everyone looks at the strange changes in the small laboratory, and they are very worried about whether Li Guocheng will kill himself.

The three of them were still with Li Guocheng before, and when the combined solution exploded for the first time, if Li Guocheng hadn't directly raised a workbench in front of everyone, everyone didn't know what the consequences would be. Since then, except for the time when materials need to be changed and cleaned up, Li Guocheng has never let them get close to this small laboratory.

"This time, Brother Li has been in for a week, and he has stayed longer than before", Zhang Zhijing recorded Li Guocheng's experimental data while chatting with everyone.

"yes, this is the longest time without an accident...

As soon as Zhou Xiaojuan finished saying this, she saw Li Guocheng rushing out with an explosive head, followed by a puff of smoke, and the smell smelled aromatic.

"Get out of here quickly, the smoke is poisonous", he said and ran to the two girls who were still in a daze, one in each hand, and ran under his armpit, looking at Yan Jiefang was still in a daze, Li Guocheng went up and kicked it.

The four of them quickly moved away from the laboratory, and some of the people who saw it walked away far away, and they were no longer in the mood to see the excitement.

If you want to watch the excitement several times a day, sometimes you will smell strange smells, vomit, or tears. Probably you are not in the mood to participate, and staying away is the best choice.

"Brother Li, I didn't have an accident for a week, I thought it was okay, but I didn't expect that you gave us a scare today", Zhou Xiaojuan didn't know what expression to have.

"You're a crow's mouth," Zhao Zhijing complained in a low voice.

"Okay, there are good things, I found materials that emit light when they are electrified, photoresists and etchants also have eyebrows, but they are not stable, as long as you are lucky, you can find the best formula", Li Guocheng's hair became colorful, but his eyes were full of excitement.

"Don't go in today, I'll clean up tomorrow when I come, I'll take a bath first", said Li Guocheng closed his breath, ran into a waterproof bag in the dark of the laboratory, ran to the front of the faucet to rinse for a while, shook it, and then took out toiletries and a change of clothes from it, and there was his quilt in it.

This is the method that I thought of after many painful lessons, otherwise these things would not have been usable by the explosion just now.

Director Li felt Li Guocheng's desperate spirit, and all his daily necessities were replaced by the factory every time. Later, Zhang Zhijing thought of the method of rainproof cloth, so she did not replace these daily necessities.

Li Guocheng ran to the factory's bathhouse in a hurry, and after one-stop service, he walked out of the bathhouse refreshingly.

Passing by the barbershop, I simply shaved my head and rode my bike home.

Zhao Ting and Aunt Liu, who went home at night, were very happy when they saw the boiled fish on the table.

"Is your research progressing?" , Zhao Ting asked happily.

Li Guocheng, who served the last tomato and egg soup, hugged Zhao Ting and kissed him, "Completely correct."
