Ye Zhenzhen patted the literature in front of the students with her hand, "These documents are the basis for stimulating our own ideas, so before Mr. Nan formally asks your ideas, read the materials carefully." ”

The three students seemed to realize that there was no hope of entering the laboratory now, so they should hurry up and read the materials, write the proposal report, and strive to impress the tutor with the ideas in their proposal report.

The students were sorted out by Ye Zhenzhen's words, and Ye Zhenzhen also went into the laboratory to do her own thing.

Less than a few minutes after entering the lab, I heard the landline phone ring in the office.

The phone in the office area is the telephone switchboard number of the entire laboratory, usually Nan Zhiqiao answers, when Nan Zhiqiao is busy, it is Ye Zhenzhen who answers, and now Ye Zhenzhen is also busy in the laboratory, Yang Fei, who is reading information in the office, is closest to the landline phone, so he picks up the phone.

"Hello, this is the zoonose lab. Yang Fei learned from Ye Zhenzhen's usual tone of answering the phone, and politely revealed the name of the laboratory.

The other party spoke English, and then looked at the caller display on the landline, which was an American number, "May I speak to Evan?"

“Hold on ， please!”

Yang Fei covered the microphone and asked Ma Hui beside him, "Whose English name is Evan in our laboratory?"

"Evan?" Ma Hui thought for a while, everyone in the laboratory knew the Chinese name, but the English name was not clear, "I don't know, or you ask Teacher Xiaoye, she knows everyone in the laboratory very well." ”

Yang Fei put down the phone and walked to the corridor between the office area and the experimental area, there is transparent glass between the corridor and the experimental area, standing in the corridor, you can see the P1 experimental area in the laboratory clearly.

At this time, Ye Zhenzhen was standing in front of the experimental table in the P1 experimental area, preparing to prepare some relevant reagents, Yang Fei saw Ye Zhenzhen, through the glass, tearing up her voice in the corridor and shouting: "Teacher Xiaoye, whose English name in our laboratory is Evan?"

Yang Fei is one meter nine tall, tall and big, with a loud voice, shouting so violently, I feel that the whole floor trembles, and the glass corridor with good sound insulation effect is usually good, under this large decibel volume, Ye Zhenzhen can still hear it very clearly.

Evan is Nan Zhiqiao's English name, he will only use it when he is abroad, after returning to China, few people know that Nan Zhiqiao also has an English name - Evan, Ye Zhenzhen because when she was in Paris, she spent a period of time with Nan Zhiqiao, in the laboratory of the Institut Pasteur, other foreign students called Nan Zhiqiao Evan.

Ye Zhenzhen stood in front of the laboratory table, waved her hand at Yang Fei in the corridor, and pointed to the internal phone on the laboratory table, indicating that she would answer it with an internal phone in the laboratory.

The caller was a foreign man who spoke English, claiming to be Nan Zhiqiao's classmate when he was studying in the United States, because a few days ago Nan Zhiqiao asked him to find some information, he didn't understand something, so he specially called to ask, the two usually use mobile phones to communicate, but Nan Zhiqiao's mobile phone couldn't get through just now, and the foreign classmate called the number of this laboratory, and Nan Zhiqiao was not there.

After asking about the situation, Ye Zhenzhen couldn't help, so she could only wait for Nan Zhiqiao to tell her what happened just now after returning to the laboratory.

After hanging up the international call, Ye Zhenzhen used her mobile phone to dial Nan Zhiqiao's mobile phone number, and the phone prompted the other party to turn off the mobile phone.

Ye Zhenzhen speculated about Nan Zhiqiao's current itinerary, when Nan Zhiqiao left the laboratory in the morning, he said that he was going to Guojing Medical Center to see the situation in the microbial forensic laboratory, and said that he could come back before noon, and now it is more than eleven o'clock, and people may be on their way back, but why is the mobile phone turned off? Could it be that the mobile phone is out of battery?

Ye Zhenzhen dialed You Kexin's mobile phone number, You Kexin is now in charge of the work of the microbial forensic laboratory of Guojing Medical Center, if Nan Zhiqiao is still there, You Kexin must know.

You Kexin answered the phone, but said that Nan Zhiqiao had indeed been here in the morning, but he only stayed in the medical center for about ten minutes, learned some general conditions, and left, and it was not yet nine o'clock when he left.

From nine o'clock to eleven o'clock, more than two hours, and from Guojing Medical Center to China's CDC, it is only about forty minutes by car, why hasn't Nan Zhiqiao come back yet?

Ye Zhenzhen was worried, it couldn't be that there was something wrong on the road, right? Ye Zhenzhen thought about all kinds of possibilities, but all of them were worrying.

I called Nan Zhiqiao's mobile phone number again, but it still showed that it was turned off, Ye Zhenzhen thought, maybe Nan Zhiqiao has something to do temporarily, maybe he is with his friends now, Nan Zhiqiao's friend, the person who is currently by his side should be Liang Chen.

Just as he was about to call Liang Chen, the door of the laboratory suddenly "beeped", and someone opened it with an access card, and a familiar figure entered the corridor.

Nan Zhiqiao wore a casual suit and carried a black computer bag back to the office.

Ye Zhenzhen hurriedly changed out of her lab coat, came out of the laboratory, walked to the door of Nan Zhiqiao's office, and symbolically knocked on the open door.

"Please come in!"

Nan Zhiqiao said as he put down his computer bag, casually pressed the boot button of the desktop computer, looked up at the door, and found Ye Zhenzhen standing anxiously with a positive face.

"Zhenzhen, what's wrong?"

Usually Nan Zhiqiao calls Ye Zhenzhen "Teacher Xiaoye" in the laboratory, but just now I saw Ye Zhenzhen standing at the door with an anxious face, and forgot to change her words for a while, and directly used her usual name.

Ye Zhenzhen walked into the office, told Nan Zhiqiao the content of the international call she had just received, and asked about the mobile phone shutdown just now.

Nan Zhiqiao explained: "On the way back from Guojing Medical Center, I met a friend temporarily, and my phone suddenly ran out of battery, sorry, I worried you. ”

For the reason that Nan Zhiqiao just said, coupled with Nan Zhiqiao's eyes and tone when he spoke, Ye Zhenzhen was instinctively very skeptical.

Nan Zhiqiao hesitated for a moment, and finally said honestly: "The phone did suddenly run out of battery, but I didn't go to see a friend, but went to the police station." ”

"What happened to the police station?!" Ye Zhenzhen was worried.

"It's nothing, just go to the police station and ask Officer Li about the 'Fire Snake Project'. ”

"Is there any new progress on the 'Fire Snake Project'?"

"Not yet, and the person with the snake tattoo I saw in the jungle that day still hasn't found any clues. ”

Ye Zhenzhen remembered the outbreak of insect-borne diseases in the western suburbs two months ago, when she and Nan Zhiqiao went to the valley near the western suburbs wildlife park to check the situation, and met researcher Zhang Liguo, who was imprisoned, and the masked man who burned down the mosquito cultivation base, and those people had a snake-shaped tattoo on their arms at that time.

As he spoke, Nan Zhiqiao had already turned on the computer, pulled up a picture from the folder, and enlarged it on the computer screen, which was the snake tattoo on the arm of the group of masked people.
