Chapter 303 Find the Flaw

Song Jinning's thinking is completely in a scientific state, and she points to a webpage opened on the computer screen: "I just checked, and there is no breakthrough in the extraction technology of graphene, 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 obtain a little bit of graphene material, he immediately died down, "Forget it, it's such a trouble."

"Well." 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 relatively easy to separate graphene with a single-layer structure. He regarded the ore as It was a gift to my father, who later gave it to me. I polished it by hand in my spare time to extract high-quality graphene single-layer wafers."

Gu Nianzhi listened to the fog, and the mosquito-repellent coils in his eyes became more serious.

She kept a smiling expression and finally listened to Song Jinning's words, and finally came to two conclusions.

First, the graphite ore with special structure was obtained by Huo Guanyuan.

Second, Song Jinning gave Huo Guanyuan a mobile phone battery made of materials polished from the ore found by Huo Guanyuan.

It can be regarded as returning to the original owner.

So someone who is interested in that phone is actually interested in the battery inside, right?

Sitting next to Song Jinning, Gu Nianzhi looked very interested in the graphene molecular formula that Song Jinning showed her, but his mind was already out of his mind.

Graphene extraction technology has not made a major breakthrough in the past ten years, which means that the person who stole the mobile phone cannot replicate Song Jinning's success.

It also shows that the 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 the battery of this mobile phone 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 a breakthrough in graphene stripping technology, capital will do anything for profit. However, you have to remember that this technology has not made any breakthroughs, so I don't think there is any breakthrough. The need to kill."

"...But others don't know..." Gu Nianzhi began to ponder the murderer's mental state, "Maybe she thought you had made a major breakthrough, and finally took the risk and stole the phone, but found nothing."

Song Jinning smiled and shook her 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 technology, she would have stolen it long ago. "

They won't wait until six years after their accident to steal, but also kill people and sell goods.

"Huh? She knows that you make this battery? That is to say, she also knows that you use special graphite ore?"

"Ok."

Gu Nianzhi tilted his head and leaned on Song Jinning's shoulder, speechless.

Well, this path seems to be blocked.

Could it be that the murderer really wasn't Bai Jinyi?

In other words, the murderer was indeed Bai Jinyi, but she took away Huo Guanyuan's personal phone for another purpose?

Gu Nianzhi's fingers tapped on Song Jinning's computer desk again and again. What is the reason that made Bai Jinyi take the risk of murder and robbing six years later?

...

Coming out of Song Jinning's room, Gu Nianzhi didn't go back to his own 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 in three shifts, 24 hours a day, 365 days a year, and there are people there every day.

It is common for Huo Shaoheng and the others to stay awake for days and nights.

"Nianzhi is here again? Are you here to ask for a beating?" Zhao Liangze rolled up his sleeves and walked over with a "grinning grin".

Gu Nianzhi made a "scared" look, sneaked into Huo Shaoheng's office, locked the door behind him, and waved his fist triumphantly at Zhao Liangze who was outside.

Zhao Liangze gestured to the door of Huo Shaoheng's office twice before giving up.

It was originally just to amuse Gu Nianzhi.

Gu Nianzhi turned around and saw Huo Shaoheng sitting behind the desk, the bright overhead light pouring down, casting flickering shadows on his face, making his facial features as beautiful and profound as a statue.

Huo Shaoheng stared at the computer screen, typing quickly on the keyboard with both hands, wearing a pair of shielded earphones on his head, as if he was talking to someone.

"Come 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 the laptop on the coffee table and winked at the transparent office wall.

But people outside can't see inside at all, just like the wall on the other side of the interrogation room, it is one-way.

Gu Nianzhi discovered it outside, so after entering, he unscrupulously made faces at the one-way transparent wall.

Huo Shaoheng finally ended the call, closed the computer program, looked up and saw Gu Nianzhi holding a pair of small white hands, using the light projected from the other side of the room, making the shapes of various small animals and projecting them on the opposite wall .

The little duck that can run, the proud giraffe, and the barking puppy can enjoy themselves very much.

Huo Shaoheng got up from behind the desk, came to sit beside her, and asked, "Have you talked to my mother?"

Gu Nianzhi nodded, took back his hand and rubbed it, and opened the graphene page to Huo Shaoheng, "Learn about that amazing battery."

Huo Shaoheng quickly read the webpage, shook his head and said, "It should not be because of the battery."

"But what exactly would the murderer do to get the phone?" Gu Nianzhi was puzzled, "If Luo Xinxue lost the phone when she died, it would have been six years since Huo Guanyuan and Aunt Song had an accident."

"Well, there is another possibility. Maybe the mobile phone was lost long before Luo Xinxue passed away, and we just discovered it now." Huo Shaoheng pointed out another possibility, "So don't be too foolish. We don't need to know what the murderer wanted with the mobile phone. What to do. We just need to prove that the murderer stole the phone from Luo Xinxue."

Gu Nianzhi immediately understood, "I see. I was thinking too much."

Focusing on the question of 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 private mobile phone number.

Under normal circumstances, the mobile company will not give you the communication records of such a long time, because it involves too much time and energy.

But with court subpoenas and pressure from the military, they had to do it.

The mobile company printed records of Huo Guanyuan's private mobile phone for them, starting to use it more than 20 years ago until now.

It is a pity that the frequency of use of this mobile phone is really too low.

Gu Nianzhi discovered that this mobile phone number has been with Huo Guanyuan for four or five years, but the mobile phone call log is only ten pages long, and there are some irrelevant text messages.

All records came to an abrupt end sixteen years ago.

That was the day the accident happened in the laboratory.

Since that day, the phone has never waited for its owner to show up.

It seems that Luo Xinxue did not use Huo Guanyuan's relic after the military department handed it over to his wife Luo Xinxue.

What is the charm of a mobile phone that has been silent for six years, so that that person would take the risk of killing people and stealing goods?

Gu Nianzhi thought so much that he didn't think about food and drink, and couldn't sleep at night, but he didn't solve this problem.

Later, Zhao Liangze couldn't see it anymore, and 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 it yet, It is very likely that the opposing lawyer has found Huo Jialan's flaw, and Bai Jinyi will be exonerated."

Gu Nianzhi sneered: "She wants to be exonerated in Luo Xinxue's case? Have you asked me?! - Besides, there is Aunt Song's case!"

This is the first update. Remind the monthly pass and recommendation ticket!

The second update will be at one o'clock in the afternoon.

Yesterday I planned to update at two o'clock, but when I uploaded it, it was already past one o'clock in the middle of the night, and I confusedly pressed "release immediately" instead of "scheduled release"...

O(∩_∩)O.
