Song Jinning's thinking was completely in a scientific state. She pointed to a web page open on the computer display: "I just checked and found that there has been no breakthrough in graphene extraction technology, so it is impossible to mass-produce this kind of mobile phone battery. "
When Gu Nianzhi heard that it took several years of manual polishing to get a little bit of graphene material, he immediately stopped and said, "Forget it, it's so troublesome."
"Yeah." Song Jinning nodded, "It was also a coincidence at that time. When Huo Guanyuan was on a mission, he got a piece of graphite ore with a special structure, from which it was easier to separate single-layer graphene. He regarded the ore as It was given as a gift to my father, who later gave it to me. I polished it by hand in my spare time to extract high-quality single-layer graphene wafers."
Gu Nianzhi listened in confusion, and the mosquito-repellent incense in his eyes became more serious.
She finally listened to Song Jinning's words while keeping a smile on her face, and finally came to two conclusions.
1. The graphite ore with special structure was obtained by Huo Guanyuan.
Second, Song Jinning gave Huo Guanyuan a mobile phone battery made of materials ground from the ore found by Huo Guanyuan.
It can be regarded as returning the property to its original owner.
So if someone is interested in that mobile phone, they are actually interested in the battery inside, right
Gu Nianzhi sat next to Song Jinning, looking very interested in the graphene molecular formula that Song Jinning showed her, but in fact, her mind was already spinning.
There have been no major breakthroughs in graphene extraction technology in the past ten years, which shows that the person who stole the phone cannot replicate Song Jinning's success.
It also shows that that person may not know that the key to Song Jinning's success lies in the graphite ore with a special structure.
"Aunt Song, do you think that just this cell phone battery will make it possible for someone to kill someone?" Gu Nianzhi tilted his head, looking at the mathematical formulas and molecular formulas on Song Jinning's computer screen like a book from heaven.
Song Jinning thought for a while, "If there is really a breakthrough in graphene exfoliation technology, capital will do anything for profit. However, you have to remember that there is no breakthrough in this technology, so I don't think there is. The need to kill.”
"...But others don't know..." Gu Nianzhi began to speculate on the murderer's mental state, "Maybe she thought you had made a major breakthrough, and finally took the risk and stole the phone, only to find that she found nothing."
Song Jinning smiled and shook his head, "If the person you are talking about is Bai Jinyi, I don't think she would do this. She is also an expert. When I was making batteries, she also knew that if she wanted to steal the technology, she would have stolen it long ago. "
He would not wait until six years after their accident to steal, but would also kill people and steal goods.
"Ah? She knows you make this battery? That means she also knows you use special graphite ore?"
"Um."
Gu Nianzhi tilted his head and leaned on Song Jinning's shoulder, speechless.
Well, this road seems to be blocked.
Is the murderer really not Bai Jinyi
In other words, the murderer was indeed Bai Jinyi, but she had another purpose in taking Huo Guanyuan's personal mobile phone
Gu Nianzhi's fingers kept tapping on Song Jinning's computer desk. What was the reason that made Bai Jinyi take such desperate risks to kill people and steal goods six years later
…
After coming out of Song Jinning's room, Gu Nianzhi did not go back to his room, but went to Huo Shaoheng's office with his computer.
It was already dark, but the office building was still brightly lit.
The staff in this office building work three shifts, 24 hours a day, 365 days a year, and there are people there every day.
It was common for Huo Shaoheng and the others to stay up for days and nights without sleeping.
"Nianzhi is here again? Are you here to ask for a beating?" Zhao Liangze rolled up his sleeves and walked over with a "smile".
Gu Nianzhi pretended to be "scared", sneaked into Huo Shaoheng's office, locked the door, and proudly waved his fist at Zhao Liangze outside.
Zhao Liangze gestured twice at Huo Shaoheng's office door and then gave up.
It was originally meant to amuse Gu Nianzhi.
Gu Nianzhi turned around and saw Huo Shaoheng sitting behind the desk. The bright ceiling light poured down, casting bright and dim shadows on his face, making his facial features as handsome and profound as a statue.
Huo Shaoheng stared at the computer screen, typing quickly on the keyboard with his hands, wearing a pair of shielded headphones on his head, as if he was talking to someone.
"Here?" Huo Shaoheng greeted her without raising his head, "Sit down."
Gu Nianzhi sat on the circular sofa area in the middle of Huo Shaoheng's office.
She put her laptop on the coffee table and winked at the transparent wall of her office.
But people outside can't see inside at all. Just like the wall over there in the interrogation room, it's one-way.
Gu Nianzhi discovered it outside, so when he came in, he made faces at the one-way transparent wall unscrupulously.
Huo Shaoheng finally ended the call and closed the computer program. He looked up and saw Gu Nianzhi holding up a pair of small jade-white hands. Using the light projected from the other side of the room, he was making various shapes of small animals, which were projected on the opposite wall. .
The little duck that can run, the proud giraffe, and the barking puppy are all enjoying themselves.
Huo Shaoheng got up from behind the desk, came to sit next to her, and asked, "Have you talked to my mother?"
Gu Nianzhi nodded, took back his hand and rubbed it, then opened the graphene page for Huo Shaoheng to see, "I learned about that amazing battery."
Huo Shaoheng quickly read the web page, shook his head and said, "It's probably not for the battery."
"But what did the murderer want to do with the mobile phone?" Gu Nianzhi was puzzled. "If the mobile phone was lost when Luo Xinxue died, it would have been six years since the accident happened to Huo Guanyuan and Aunt Song."
"Well, there is another possibility. Maybe the phone was lost long before Luo Xinxue died, but we just discovered it now." Huo Shaoheng pointed out another possibility, "So don't get into trouble. We don't need to know what the murderer wants from the phone. What to do. We just need to prove that the murderer stole the phone from Luo Xinxue."
Gu Nianzhi immediately understood, "I understand. I think too much."
If you focus on where the phone is, it will be much easier to find the direction.
…
The next day, the mobile company sent them all the records of Huo Guanyuan's personal mobile phone number.
Under normal circumstances, mobile companies will not give you communication records from such a long time ago because it involves too much time and energy.
But with court subpoenas and military pressure, they had to do it.
The mobile company printed out the records of Huo Guanyuan's personal mobile phone for them, from the time he started using it more than 20 years ago until now.
Unfortunately, the frequency of use of this mobile phone is too low.
Gu Nianzhi discovered that this mobile phone number had been with Huo Guanyuan for four or five years, but the phone call record was only ten pages long, and there were some insignificant text messages.
All records came to an abrupt end sixteen years ago.
That was the day there was an accident in the laboratory.
From that day on, this phone never waited for its owner to show up.
It seems that after the military handed over Huo Guanyuan's relics to his wife Luo Xinxue, Luo Xinxue never used them.
What is the charm of a mobile phone that has been dormant for six years that makes that person take such desperate risks as to commit murder and steal goods
Gu Nianzhi couldn't think about food and tea, and couldn't sleep at night, but she still couldn't solve this problem.
Later, Zhao Liangze couldn't stand it anymore, so he pulled her out of Huo Shaoheng's office and stuffed her into the computer chair next to his desk. "You can run the program for me. The court will start in one day. If you haven't found out yet, It is very likely that the opposing lawyer has found a flaw in Huo Jialan, and Bai Jinyi will be acquitted."
Gu Nianzhi sneered: "She wants to be acquitted of Luo Xinxue's case? Have you asked me?! - Besides, there is also Aunt Song's case!"

This is the first update. A reminder about monthly tickets and recommended tickets!
The second update will be at 1pm.
I originally planned to update at two o'clock yesterday, but when I uploaded it, it was already past midnight here. I confusedly pressed "publish immediately" instead of "publish scheduled"...
