Ye Zhenzhen pointed to the mulberry in the center of the crowd, "Who bought the mulberry? ”

"I didn't buy it, I picked it in the central compound. ”

"We're going to pick it. ”

Zhang Wen pointed to herself and Zhang Xiaolong beside her, "The two of us had breakfast in the central cafeteria, and when we passed by the mulberry forest, we picked a little by the way." ”

"Can you eat the things in the center?" Ye Zhenzhen was a little skeptical.

"It's okay, every year at this time of year is when the mulberries are ripe, many students go to pick them, the teachers don't care, and the center leaders don't say, besides, if we don't pick them, the mulberries will rot on the ground, what a pity." ”

Ye Zhenzhen picked up a mulberry and put it in her mouth, it was sweet, with a green and astringent taste of mulberry leaves, "Well, yes, it's sweeter than the mulberries sold in the market." ”

A large group of people in the experimental group gathered around the conference table to eat mulberries, and it was early in the morning, and the students did not dare to be so bold when Nan Zhiqiao was usually there.

The mulberry forest in the central compound, has been many years, before the construction of the center site has existed, after the completion of the central compound, this mulberry forest has also been retained, although the mulberry forest has years, but the mulberry trees inside are not big, are some wild small mulberry trees thinner than the arm, the branches are low, standing under the tree can be to the mulberry on the branches, Zhang Wen and Zhang Xiaolong just a while to pick such a big lunch box.

Several students in the experimental group gathered around the conference table, eating mulberries and chatting about scientific research gossip, but in a few minutes, a box of mulberries was swept away.

After eating the mulberries, the students chatted a few more words around Zhen Zhen, and the topic quickly shifted from the experiment to Nan Zhiqiao.

The students are very concerned about the current situation of their mentor, and Ye Zhenzhen said "I still need to recuperate for a while" as the official answer, and did not mention anything about Nanmu Group and the Stem Cell Research Center.

After the gossip, the students took the initiative to enter the laboratory and were busy with their own things.

Ye Zhenzhen also has a lot of things, in addition to the experimental work, there is also the project application that Nan Zhiqiao explained to follow up, and the information about the subject is all in Nan Zhiqiao's office computer.

Entering Nan Zhiqiao's office, turning on the computer, and about to copy a few files, suddenly a dialog box popped up in the lower right corner of the computer screen, which was a chat tool that was automatically launched when the computer was turned on.

The avatar on the dialog box is a real photo, a beautiful woman, slightly curly long hair, delicate facial features, no matter how you look at it, she is a beauty, the signature next to her is Lin Weiyin, and there is a simple message in the dialog box, "Brother Qiao, I just heard about Uncle Nan and Nanmu Group, I'm sorry, when you were sad, I didn't accompany you, I will fly back tomorrow and meet and talk." ”

Looking at the tone of this message, it should be Senior Nan's friend, and the relationship is not bad, but why has Senior Nan never mentioned the name Lin Weiyin?

Looking at the day of the message, it was yesterday, which means that Lin Weiyin will come back today, but Senior Nan is going to fly to the United States this morning, and the two just staggered.

Senior Nan has been busy investigating the matter of the Nanmu Group Stem Cell Research Center in the past few days, and he doesn't seem to have time to go online, and he hasn't seen this news, do you want to notify him now.

After copying the information, Ye Zhenzhen picked up her mobile phone and looked at the time, at nine o'clock in the morning, Senior Nan should be waiting for the plane in the waiting room now, the mobile phone should not be turned off yet, and it is still too late to notify.

Ye Zhenzhen called up Nan Zhiqiao's number from the mobile phone address book, and was about to dial it, when a panicked shout came from the laboratory, "Teacher Xiao Ye, come on, Zhang Wen has an accident." ”

The shouting was panicked, listening to the voice, like the voice of Li Guoyi, a graduate student in the experimental group.

Don't care about making a phone call, Ye Zhenzhen ran out of Nan Zhiqiao's office, and in the corridor, through the glass window, she saw that in the laboratory, Zhang Wen fell to the ground, her face was pale, cold sweat was dripping, and there was a pile of purple vomit beside her.

Several students gathered around Zhang Wen, busy with their hands, some supporting Zhang Wen, and some holding tools to clean up the vomit.

Ye Zhenzhen swiped the door curfew and trotted into the laboratory.

"Zhang Wen, what's wrong with you?" asked Ye Zhenzhen, half-squatting beside Zhang Wen.

"Belly...... My stomach suddenly hurt......" Zhang Wen was covered with cold sweat, holding her stomach, and screaming in pain.

Ye Zhenzhen reached out and gently pressed Zhang Wen's stomach, her stomach was a little tight, which was a symptom of gastrointestinal cramps, "It's like food poisoning, what did you eat in the morning?"

"I didn't eat anything, just ate a bowl of porridge, an egg, and a pie in the central cafeteria. ”

Zhang Wen replied weakly, pointing to Zhang Xiaolong beside him as she spoke, "The breakfast that Xiaolong ate with me was also in the central restaurant, and he ate the same, why is he okay?"

Before the words fell, Zhang Xiaolong on the side also covered his stomach, his face turned pale, "I also suddenly have a stomachache." ”

Is it really a problem with breakfast in the central cafeteria?

Just when everyone was so suspicious, Li Guoyi, who was cleaning up Zhang Wen's vomit on the side, suddenly made a "wow" sound, and a lump of purple-red liquid spit on the ground.

Ye Zhenzhen's attention shifted to Li Guoyi.

Li Guo held his stomach with one hand and bent over with a pale face, "I'm not feeling well, but I haven't eaten at the central restaurant in the morning." ”

It's not the central restaurant, but what is it?

Several possible reasons quickly flashed through my mind, the three of them had been exposed to the same environment, the same things they had eaten, the three of them had come on the same bus, and they were doing experiments in the same laboratory......

Could it be a toxic leak from a laboratory?

Ye Zhenzhen glanced at the small warehouse of toxic chemicals in the corner of the warehouse, the two locks outside the warehouse were firmly hung on it, the small warehouse of dangerous goods implemented double and dual-key management, one of the keys was in Zhen Zhen's hand, and the other key was in Nan Zhiqiao, to open the warehouse door, two keys were needed to be used at the same time, and his own key was in the desk drawer, and no one had touched it.

Could it be a strain leak?

"Teacher Xiaoye, my stomach hurts too. ”

"Teacher Xiaoye, I'm also ......"

"Teacher Xiaoye......"

Before Ye Zhenzhen could analyze the reason, the students in the laboratory showed symptoms one after another, everyone was pale, sweating on their foreheads, dizzy and stomachache.

Ye Zhenzhen's stomach also began to stir as if something was stirring inside, her stomach and intestines cramped like pain, her heart beat faster, and her whole body broke out in a cold sweat.

"Oh no, the whole lab has symptoms, it looks like it's really a problem in the lab. ”

Ye Zhenzhen analyzed the current situation in her heart, decisively picked up her mobile phone, flipped to Nan Zhiqiao's number, and was about to call, but thinking of Senior Nan's eager eyes to find out the truth, she hesitated in her heart, slipped her hand, and dialed the phone number of Director Gao of the Institute of Infectious Diseases.

Briefly explaining the situation, because it was suspected that it was a leak of toxic substances in the laboratory, Director Gao ordered all the experimenters to withdraw from the laboratory, the laboratory was closed, and the experimenters were sent to the nearby Xiaotangshan Infectious Disease Hospital for isolation and treatment.
