Hello, Mr. Major General

Song Jinning’s thinking is entirely in a scientific state. She pointed to a webpage opened on the computer screen: “I just checked and the graphene extraction technology has not broken through until now, so this kind of mobile phone battery is impossible to mass produce. "

Gu Nianyi heard that it took several years to get a little graphene material by hand polishing, and immediately died down, "Forget it, it's so troublesome."

"Yeah." Song Jinning nodded, "At that time, it was also a coincidence. When Huo Guanyuan was on the mission, he obtained a piece of graphite ore with a special structure, from which a single-layer structure of graphene could be easily separated. He regarded that ore as The gift was given to my father, and my father later gave it to me. In my free time, I use manual polishing to extract high-quality graphene monolayer wafers."

As Gu Nianzhi listened to the clouds, the mosquito coils in his eyes became more serious.

She kept a smiling face and finally finished listening to Song Jinning's words, and finally came to two conclusions.

1. Graphite ore with a special structure was obtained by Huo Guanyuan.

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

It can be regarded as the original owner.

So someone 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. In fact, he was already out of mind.

There has been no major breakthrough in graphene extraction technology in the past ten years, indicating that the person who stole the phone could not 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 this mobile phone battery will make people have the possibility of killing?" Gu Nianzhi tilted his head and looked at Song Jinning's full screen of mathematical formulas and molecular formulas on Song Jinning's computer screen just like reading a book.

Song Jinning thought for a while, "If the graphene stripping technology really has a breakthrough, and capital is for profit, everything can be done. But you must remember that this technology has no breakthrough at all, so I don't think there is The need to kill."

"...But others don't know..." Gu Nianzhi began to figure out the mental state of the murderer, "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 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 made batteries, she knew that if I wanted to steal technology, she would have stolen it. "

They won't wait until six years after their accident to steal, and they will kill people and overtake them.

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

"Ok."

Gu Nianzhi's head tilted, and she was speechless leaning on Song Jinning's shoulder.

Well, this road does not seem to work.

Isn't the murderer really Bai Jinyi?

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

Gu Nianzhi's fingers tapped on Song Jinning's computer desk without a single click. What was it that made Bai Jinyi take the risk and kill others in six years?

...

Coming out of Song Jinning's room, Gu Nianzhi did not go back to his room, but took the computer to Huo Shaoheng's office.

It was dark, and 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 people are there every day.

It is more common for Huo Shaoheng to stay up for days and nights.

"Nianzhi is here again? Are you here to beg for a fight?" Zhao Liangze rolled up his sleeves and walked over with a "smirk".

Gu Nianzhi made a "fear" look and slipped to Huo Shaoheng's office, locked the door behind him, and shook his fist at Zhao Liangze, who was triumphantly outside.

Zhao Liangze gestured twice at the door of Huo Shaoheng's office, and then gave up.

It was meant to play with Gu Nian.

Gu Nianzhi turned around and saw Huo Shaoheng sitting behind his desk, with the bright overhead light pouring down, casting a clear shadow 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 shielded headset on his head, as if he was talking to someone.

"Come?" Huo Shaoheng greeted her without raising his head, "Sit down."

Gu Nianzhi sat in the ring-shaped sofa area in the middle of Huo Shaoheng's office.

She put the laptop on the coffee table, winking at the transparent wall of the office.

But people on the outside can't see the 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 coming in, he unscrupulously made faces at the unidirectional transparent wall.

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

The little duck who can run, the haughty giraffe, and the barking puppies are very happy.

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

Gu Nianzhi nodded, retracted her hand and rubbed it, and opened the graphene page to Huo Shaoheng, "Learn about that kind of amazing battery."

Huo Shaoheng quickly finished reading the web page and shook his head: "It shouldn't be for the battery."

"But what exactly does the murderer want a cell phone to do?" Gu Nianzhi was puzzled. "If the cell phone was lost when Luo Xinxue 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's death, but we only found out now." Huo Shaoheng pointed out another possibility, "So don't be horny. What to do. We only need to prove that the murderer stole the phone from Luo Xinxue."

Gu Nianzhi immediately understood, "I know. I think too much."

Focusing on the question of where the phone is, it is much easier to find the direction.

...

The next day, the mobile company sent them all the records of Huo Guanyuan's personal phone number.

Under normal circumstances, mobile companies will not give you such a long time communication records, because too much time and energy are involved.

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

The mobile company printed the record of Huo Guanyuan's personal mobile phone, which has been used since more than 20 years ago and has been used until now.

Unfortunately, the frequency of use of this phone is too low.

Gu Nianzhi discovered that this mobile phone number followed Huo Guanyuan for four or five years, but the phone call records were only ten pages of paper, and there were some irrelevant text messages.

All records stopped abruptly sixteen years ago.

That is the day the laboratory accident occurred.

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

It seems that after the military department gave Huo Guanyuan's relics to his wife Luo Xinxue, Luo Xinxue has not used it either.

What is the charm of a mobile phone that has been silent for six years that makes that person take risks and kill others?

Gu Nianzhi didn't think about tea and rice, and couldn't sleep at night, but he didn't solve this problem.

Later, Zhao Liangze couldn’t see it anymore. He pulled her out of Huo Shaoheng’s office and stuffed it on the computer chair next to his desk. “You can run the program for me. The court will be held in one day. If you haven’t found out yet, It is very likely that the opposing lawyer found Huo Jialan's flaws, and Bai Jinyi will be exonerated."

Gu Nianzhi sneered: "She wants to get acquitted in Luo Xinxue's case? Have you asked me?!-Besides, there is also the case of Aunt Song!"

This is the first one.Please remind me of monthly and recommended tickets!

The second one is one in the afternoon.

Yesterday, I planned to update at two points. When the result was uploaded, it was already over one in the middle of the night on my side. I confused "Release immediately" as "Timed release"...

O(∩_∩)O.
