She originally thought that this son-in-law was a reliable person. Although she didn't like it very much, she could recognize her with her nose.

No matter how many shortcomings he has, it is not a big problem.

As long as his daughter likes her, as long as he can make her happy, it doesn’t matter whether he has money or not, whether he has the ability or not.

But now it seems that some things in life are destined to be gone.

"Shen Chong, please make it clear. This is a research result that a team of hundreds of people has spent years of hard work and hundreds of millions of dollars. This represents the next important development direction of my country's battery energy industry and an important policy for my country to carry out technological competition with countries around the world! Why do you deny it in a blank voice? If you are at this level, then I'm afraid I really have to reconsider what you and Zhishu are doing."

The atmosphere in the study suddenly became heavier, and Shen Chong was sober that he was so proud.

not good!

Unexpectedly, I was so careful that I could still make a fuss.

He was a little embarrassed. Not long ago, he personally agreed to the child's mother that he must be more responsible to his mother-in-law and be less careful and endure more.

I never thought that my previous efforts were wasted for a moment. Forget it, let’s get away with it.

He smiled awkwardly and apologized, "Auntie, I'm sorry, I'm talking nonsense. Don't care, sorry."

After saying that, he wanted to leave, but Qin Yun became really angry and didn't plan to let go of this arrogant and arrogant person.

Although she was just saying something angry, she wouldn't really break up the couple by doing this, and she couldn't beat him.

But the mother-in-law felt that she should teach her son-in-law who was more willing to give advice to her because of her talent, so as not to have similar situations in the future.

Qin Yun has dealt with many madmen. When she was young, she offended people a lot because of academic disputes. She has her own opinions on geniuses.

Appropriate suppression of geniuses can help him learn to be low-key and humble in his future life, and be able to truly calm down and do things.

"Shen Chong, stop."

Qin Yun's calm voice sounded behind Shen Chong.

He paused.

Alas, I can't get away, he turned around and bowed, "Auntie, I was wrong, really wrong. Just treat what I just said as a gust of wind and pass it over with a snort."

Qin Yun shook her head, moved the chair slightly to the side, and then patted another stool, "Since you said there is something wrong with the material of the polymer diaphragm, I am really interested in listening to it."

"How can you have any high opinions? You're just blind."

Shen Chong's vest was a little cold.

The mother-in-law suddenly calmed down after being angry, which was obviously the tranquility before the storm came.

The calmer she is, the more terrifying she appears and can bring a strong sense of oppression.

The mother-in-law's emotional regulation and disguise ability are exactly the same as the child's mother!

Lao Lin also learned this from her!

"I don't think you're nonsense. You didn't mention the electrodes, electrolytes, and metal shell coatings, and you didn't even mention the discharge stability and voltage of the battery. Just looking at the polymer diaphragm means you have an idea in your mind. How do you get this threshold for two years? Let's talk about it."

Her tone was calm, but she had no room for negotiation.

Her subtext is that if you don’t tell me one by one, then don’t think about leaving today!

Shen Chong sighed inwardly, "Okay, there's nothing I can do."

If there is a way in heaven, you don’t go, and if there is no way in hell, you have to break through. Take it!

He coughed lightly and walked forward, "Then I'll talk about it?"

Qin Yun suddenly felt that the momentum of this son-in-law was slightly different from before, and she felt a little nervous, and she was as arrogant as the rumored one.

What an arrogant and late child!

"Okay, I'll listen."

She said.

Shen Chong smiled, "Is this a woven diaphragm mainly made of polypropylene?"

"right."

Shen Chong said again: "Polypropylene diaphragm, also known as PP diaphragm. Currently, the best in the world are island countries and the United States. Auntie, do you hope that the company you invested in will break the monopoly position of other countries in the diaphragm field while conquering lithium iron phosphate battery technology?"

Qin Yun was surprised when she saw that he had the idea and nodded: "Yes, although our country is strong now, it has a great victory or defeat with other countries in many fields. As for the battery separator, we have to make tens of billions of profits every year. At present, we can only replace low-end products, and high-end products are extremely dependent on imports."

Shen Chong continued: "Then I can only say that you are thinking too much. For this project, its next move should be to improve weaving, synthesis and purification processes, and try to improve the stability and mechanical properties of the PP diaphragm, right?"

Qin Yun was really shocked this time.

The key part of the paper she just read does mention this step of research and investment direction.

But Shen Chong did not see that part of the paper.

In addition, this matter is top secret. No third person in the world knows about it except her students and herself!

"How did you know?"

When Shen Chong saw Qin Yun's expression, he knew that he had made the decision.

The bankrupt company in his previous life was kneeling in this direction.

"It's useless, without innovation, no matter how much you improve it, you can't pass the upper limit of two years! The diaphragm made with your weaving process like Auntie, lacks inert molecules on the surface, and its alkali corrosion resistance can only be increased by 50% at most! In addition, our country has a large land and materials, and the temperature difference between the north and the south is extremely large. The temperature in the north is low in winter, and the PP diaphragm has very poor low temperature resistance. Not to mention two years, it will have to crack in one year. Following this process, you will be on the wrong path from the beginning. The deeper you go, the further you will be wrong!"

Since the mother-in-law sincerely asked for a slap in the face, Brother Shen decided to fulfill it.

As the saying goes, the country is easy to change and the nature is hard to change. There are really no way to do anything. Once his engine is ignited, it will not stop the car.

Qin Yun argued angrily, "You are completely unfounded inferences. Why do you make a conclusion without the support of experimental data?"

Shen Chong smiled proudly, ignored his mother-in-law's questioning, and said to himself: "At present, the main emerging market in the domestic battery industry is new energy vehicles. So let me ask you, put aside the corrosion resistance point, just talk about low temperatures. In the future, new energy vehicle manufacturers who use your batteries will have to sell only the south and not the north? Or must consumers not drive to the north? Can this kind of product be sold? Is there any value for projects without a market?"

Qin Yun stood up from the chair, "I'll ask where your conclusion comes from, don't talk about other places!"

Shen Chong took the paper and pen and sighed, "Okay, let's analyze it."

After saying that, he began to write and draw on paper, first writing out the molecular formula of the main material of the polypropylene diaphragm and then writing out the molecular formula of the auxiliary material.

"The result of this weaving process is like this..."

"Under alkaline conditions, the process of potential transfer is like this..."

"After the battery is fully charged, all lithium ions are on this side, and electrons will constantly impact on the other side, changing the electricity price in the polymerization film. No matter how small the probability of reaction occurs, it is still inevitable."

"To sum up, with the current weaving process, no matter how you modify it, it will be useless!"

Qin Yun didn't believe it at first, so she snatched the draft paper full of writing from Shen Chong and read it all the way at a very fast speed.

The more she looked, the more she became more frightened, and the more she looked, the more she became the more unbelievable she became.

Although this is not her most professional field, her knowledge is often the same. Qin Yun has a wide range of personal knowledge, including physics, chemistry and machinery.

The broad knowledge and grand view of the overall situation are the fundamental reason why she can bring many students who have made achievements in various fields from a high perspective.

She could tell whether there were any real guys in Shen Chong's writings at first glance.

After a long time, she put down the paper and couldn't speak for a long time.

The logic is rigorous, the formula is correct, and the inference is reasonable. This is just her initial judgment.

But what's even more terrifying is that Shen Chong made the final decision of her students.

Even a complete inference was made for each research stage, and every time, he guessed the lower limit of each research stage.

"Auntie, although science needs practice to prove that there may be a lower limit and an upper limit for every research progress. If your student's research can push every step to the upper limit, even if it can only be in the middle, it may actually barely reach a service life of three to five years. But I can only regret to tell you that my judgment is that the progress of each research will be at the lower limit, and it will indeed exceed two years in the end!"

Shen Chong picked up the paper and explained it line by line.

His conclusions are certainly reasonable and seamless.

It seems to be a reason, but in fact it is just a retelling of the demise of the unlucky company in the previous life.

It was originally based on facts, so he almost moved out other people's experimental data.

It’s not that he doesn’t want it, it’s that he doesn’t know that the thing is kept secret after all, so he can only disguise what has happened as inferences.

But Qin Yun knows how to do things, and can see the spots and know the leopards.

Theory is the prerequisite for practice.

Practice is the support of theory.

"You've done this before? Where is your lab?"

What Shen Chong wrote was too real. Qin Yun changed his previous judgment and thought that he was not empty-mouthed. He just didn't expect that in such a busy state, he still had the energy to dabble in other aspects and had such in-depth research.

Shen Chong spread his hands, "There is no laboratory, I haven't studied this in depth, I just read some papers."

"You can reach this level just by reading the paper?"

Qin Yun's eyes widened, feeling that he was talking nonsense.

It’s not that she has never seen the world, but she has seen more and more. Shen Chong’s research level is not particularly exaggerated. Just the project team her students are leading now can naturally achieve it after steadily advancing.

But what she was afraid of was that the result was really as Shen Chong said, which meant that ten billion yuan of funds were wasted, leaving only some patents that might be useful or useless.

What you lose is not just money, but also time, and the market.

This has always been the case with technological competition, losing one step at a time.
