Ten minutes later, five people were sitting in a small conference room on the twelfth floor. They were Professor Bu, Meng Fei, Xiao Han, security director Doruke, and Mi Rong.

One side of the conference room is a brown soundproof wall, and the other side is an entire exterior wall made of transparent glass windows.

If it were a normal day, the scenery and lighting here would definitely be very good. But now it's pitch black outside, like a big black mirror, only reflecting the scene in the room.

Mi Rong was a little disheveled and her hair was particularly messy. She screamed, roared and protested all the way. But with the persistence of the security guards, she was sent in anyway.

In the end, she sat down in the conference room a little tiredly, staring like a madman at Professor Bu, who was turning his face and denying anyone else, and her ex-husband, who was obviously a fake.

"First of all, I want to declare that I am indeed not Zhang Feng."

Meng Fei decided to go straight to the point and tell the truth "honestly" because Mi Rong had already screamed many times in Qingmang, Taotie and Shenhu. There was no point in continuing to pretend.

"My name is Zhang Yu, and I am Zhang Feng's twin brother. I work in the Criminal Investigation Department of Wutong City, Qingmang Republic. To put it simply, I am Zhang Feng's brother and a criminal investigator."

Meng Fei shamelessly fabricated it.

"Fart!" Mi Rong was almost going crazy, "Why have I never heard that he has a twin brother, or is he a prisoner?"

"Haha." Meng Fei sneered, "This is very simple. Just go to your husband's hometown and check the household registration information. Have you checked it?"

Have you checked? Obviously not. Although she asked Zhang Feng about his family situation, what Zhang Feng told her may not be true. Can you check? The Internet is disconnected now, so check it out.

Meng Fei made it up without any scruples because everything in the Nautilus Building was under isolation and it was impossible to verify it normally.

"So, you entered the institute as an imposter?"

Professor Boulanger's eyes were a little uncertain. A guy who seemed to him to be unlearned and unskilled actually infiltrated his institute under his name. This was simply a stain on the sacred academic research.

As for the security director, Doruke, his face was even uglier. Outsiders had sneaked into the institute, but he knew nothing about it. This was a serious dereliction of duty.

"That's right."

Meng Fei nodded.

"But I have only one purpose here, and that is to track down the murderer of my brother!"

When he stated this reason, Boulanger and Doruke's expressions suddenly changed from vigilance to sympathy. Boulanger was especially shocked:

"What did you say? Zhang Feng is dead?"

In his opinion, this was a once-in-a-millennium young genius, the star of hope for the artificial intelligence industry, who died so easily?

Meng Fei activated the micro-management and said with a sad expression:

"He ate a bowl of poisonous noodles and died of poisoning in the dormitory. Because no one had entered or left his room before his death, the criminal investigation officer determined that he had committed suicide.

"But I think there are still doubts in it. Therefore, I suggest not to publish the news of Zhang Feng's death. After cleaning up the scene, I lived in Zhang Feng's place for a while and continued to investigate the murderer.

"I suspect that the real murderer is actually Zhang Feng's ex-wife, who is sitting here now."

Meng Fei glanced meaningfully at Mi Rong, who was sitting opposite.

"Because she was about to leave Qingmang and go to the Divine Tiger Alliance soon, and my evidence was not sufficient. I had no choice but to pretend to be Zhang Feng and come here to continue the investigation."

"What nonsense! Who doesn't know how to spray blood on someone?"

Mi Rong is like a liar who gets exposed and becomes angry with shame.

"I didn't even know he was dead! Why did I kill him? It's been several months since the divorce. Am I sick if I go back to kill him? Besides, I've never been back to school, how could I kill him?"

Meng Fei took out his mobile phone, connected it to the projector, and opened the Pipa Fish shopping app.

"The key evidence why Zhang Feng's death was confirmed as suicide is this."

"Purely natural plants, ancestral fresh and tonic condiments."

The highly poisonous "Wu Tou Fen" was displayed. Of course Boulanger and Doruke couldn't understand it, but Xiao Han explained it in quite fluent Taotie dialect.

Mi Rong's eyes changed suddenly, but immediately returned to calmness. She was temporarily dormant like a poisonous scorpion.

"When Zhang Feng died, there was this thing in the drawer with his fingerprints on it. And no one else entered or left his room at that time.

"We extracted his online shopping records. This item was indeed purchased using his account to log in. So we took it for granted that he placed the order.

"But we overlooked one thing. Three months ago, Zhang Feng's online shopping list had almost everything. For example, skin care products. Women's skin care products are very complicated, and most men can't understand them at all.

"These orders cannot be placed by Zhang Feng. They should be placed by his wife at the time, Mi Rong. They share an online shopping account.

"So the poisonous Wutou powder purchased by logging in to Zhang Feng's account was not ordered by Zhang Feng, but by Mi Rong!"

"This is really bullshit reasoning."

Mi Rong tied a strand of hair on her head that had become messy due to her madness, and cheered up like a cockfighting cock.

"I have Zhang Feng's account and password, which is correct, but you assume that the Wu Tau powder he ordered was from me? Isn't this nonsense? Where's the evidence?"

Meng Fei shook his cell phone.

"According to the latest "Personal Privacy Protection Law", online shopping platforms are not allowed to save the login location of the account on the server without authorization. I think you must know this, so you are confident.

“But if the app client saves the login location locally, because the information is on the user’s own phone and is not uploaded to the server, it does not leak privacy.

"For some apps, if another mobile phone logs in to the same account, the location of the previous login will be sent as a warning message.

"For example, my mobile phone belongs to Zhang Feng. If you have logged in with Zhang Feng's account on your mobile phone, then next time I log in on Zhang Feng's mobile phone, I can see the location where I logged in the previous time.

"The information saved on the mobile client can also be used as evidence."

"What's the use of seeing the location where you logged in last time?"

Mi Rong's face was already a little stiff.

"Log in a few more times and this location will be covered!"

"The coverage is only superficial."

Meng Fei quickly pressed the phone to enter file browsing, and then opened a log file.

"Although it appears that the previous login location has been overwritten, these locations are actually saved in a log file. You can see this clearly here.

"8022-12-4, 3:10, logged in at No. 91 Yuma Village, Huaihua City, Jiangnan Province.

"If I am not mistaken, on December 4, 2022, Zhang Feng stayed in the Qingmei University graduate student apartment, right? There is surveillance video to confirm. How could he log in in Jiangnan Province?

"Where is No. 91, Maize Village, Huaihua City, Jiangnan Province? If I remember correctly, Miss Mi's hometown is in Huaihua City, Jiangnan Province?

“And more importantly, look at this Wu Tou powder’s purchase record:

“The order was placed at 3:30 am on December 14th.

"Ms. Mi, you logged into Zhang Feng's account at 3:10 in the morning, and then placed an order with his account at 3:30 in the morning to buy the pack of Wu Tau powder. Do you have anything else to explain?"
