When Yan Yu woke up from the sofa, it was already the next morning.

Jiang Huijie was still busy on the edge of the test bench, with dozens of slides on the table, marked with numbers waiting for screening.

It was still raining heavily, and there was no sign of stopping.

"Awake?" Jiang Huijie stopped what she was doing and poured Yan Yu a glass of water.

After sleeping all night, Yan Yu regained a lot of strength, looking at Jiang Huijie's dark eyes, tired look, and haggard and yellow face, he was also very distressed.

He pulled the ends of Jiang Huijie's hair behind his ears and said softly, "Thank you for your hard work......

Jiang Huijie smiled softly: "I just finished sampling, and I can observe and analyze it right away, you go and see the situation of other people first." ”

"Others?" Yan Yu suddenly came back to his senses and hurriedly asked, "Guan Rui and Hong Dafu are back?" ”

Jiang Huijie nodded: "I'm a little injured, but it's not a big problem, I'm resting in the consultation room." ”

"Then I'll go check it out first, and I'll find you something to eat by the way."

Yan Yu put his hands on Jiang Huijie's shoulders and helped him knead them for a while, the strength was moderate, the technique was gentle, the cold hairs on the back of Jiang Huijie's neck stood up, and her face suddenly turned red.

"Alright, alright, let's go."

Yan Yu smiled at her and left the lab.

He was really hungry, his whole body was weak, his legs and feet were shaking, and when he arrived at the clinic, Liang Shumei and others were also there.

Hong Dafu was smoking outside the door, and when he saw Yan Yu coming, he just nodded, stepped on the cigarette butt, and followed Yan Yu into the consultation room.

"Are you alright?" Yan Yu saw that the corners of Guan Rui's eyebrows were cracked, and he hung his left arm with a bandage, and he was also a little worried.

Guan Rui shook his head: "It's okay, it's just dislocated...... It's good to get used to it after a while. ”

Yan Yu saw that everyone was there, so he said to Yu Guofeng: "Team Yu, is there a way to take Uncle Shi and them over?" ”

Yu Guofeng was also extremely tired, after all, he had been running all night in the heavy rain, and he was only relying on cigarettes to boost his spirits at this time.

At this time, he also frowned and said, "It's a little difficult...... They are in Dunhuang Mountain, it is raining so heavily, the road is not easy to walk, and they can't enter the mountain, and I have already called this morning, saying that there is a flash flood over there and there is a mudslide......"

"There was a mudslide?" Yan Yu was startled at first, but soon rejoiced.

Obviously, Liang Shumei had already told Yu Guofeng what happened last night, otherwise when he heard Yan Yu want to take everyone over, he would inevitably ask the reason, since he didn't ask, he should know.

Although the mudslide blocked the way for Yu Guofeng and others to go in to pick up people, it also blocked the way for the murderer to go in and kill people.

In other words, Zhao Tongyi and Zhao Tongxuan and other old guys in Dunhuang Mountain should be safe for the time being.

The target of the murderer was the people who had participated in the destruction of the underground base, and at that time, Meng Jiefang and others had already taken the lead in leaving, and only the people from Dunhuang Mountain and Yu Guofeng entered it, and other than that, there was only Yan Yu.

At present, these people are all in the base, as long as they are on guard, the murderer should not find a chance to kill.

"For the sake of safety, take Meng Jiefang and them all over." Yan Yu is not at ease in the end, after all, the murderer is extremely conceited, if he can't find a chance on Yan Yu's side, it is not ruled out that he will kill people indiscriminately.

As for the innocent people in the people, Yan Yu didn't have to worry, because the murderer was too conceited, if he killed a civilian casually, his pride would not allow him to do so.

Yu Guofeng nodded, and let Hong Dafu arrange it.

He asked, "When will the results of the analysis come out?" ”

Obviously, Liang Shumei said everything she knew, and she didn't have to talk nonsense again.

Shaking his head, Yan Yu replied: "I just finished sampling, and I was about to observe and analyze, but ......"

Yu Guofeng became nervous: "But people are iron and steel, and they can't do anything when they are hungry......"

It seemed that Yan Yu was still in the mood to joke, and Yu Guofeng also laughed: "Scared me, I thought it was a big deal, you go to the cafeteria first." ”

Yan Yu also smiled.

It's not that he has a big heart, but that the murderer threatens to kill one person a day, and now it's dawn, that is, the murderer may kill at any time, how can he be relaxed.

It's useless to just worry and be afraid, and seizing the time to recover your strength is the best way to deal with the murderer.

Maybe it's because it's raining, everyone is celebrating, or maybe it's the enemy at the moment, and they need to boost their morale, the food is very good, Yan Yu finished eating, and returned to the laboratory.

Jiang Huijie paid great attention to details and was meticulous, and after dealing with the matter at hand, she sat down and had a meal with Yan Yu in a hurry.

After a full meal, the blood sugar concentration increased, and Yan Yu began to feel a little sleepy, and even a little too lazy to move, but he couldn't do this.

Yu Guofeng's people had already brought everyone else back, after all, it was daytime, and the visibility was much higher than at night, and they had prepared early, which was considered smooth.

Zhang Gulin and others were also picked up, and when they saw Yan Yu again, they were also sad and happy, after all, everyone thought that Yan Yu could not survive.

For the rest of his life after the catastrophe, Yan Yu was naturally very happy to meet again after a long absence, and chatted with everyone for a while, talking about the current situation, everyone was somewhat panicked.

There is no more information about the identity of the murderer at this time, and it can even be said that there is no clue, and there is not even a suspect candidate.

A group of people thought silently, and the tense atmosphere gradually dispersed.

"Let's rest first, the base has strengthened its vigilance, and I have already called Hu Ju, and more people will be sent over."

Yu Guofeng also does not want to create unnecessary panic, but it is imperative to do a good job of safety and security.

"Let's concentrate in the inpatient building, the entrances and exits have all been blocked, the murderer can't get in unless he can be invisible, so don't be too afraid."

Yu Guofeng's words brought some comfort, but Yan Yu felt very uncomfortable in his heart.

Because it's basically a reversal of roles.

They should have taken the initiative to hunt down the murderer, but now they are the opposite, because of the threat of the murderer, they can only defend passively, which will bring great frustration.

But it was pouring rain outside, and the murderer didn't leave any clues, so there was no way to take the initiative to attack.

The only hope is the results of Jiang Huijie's analysis.

It's just that Yan Yu has seen the densely arranged slides to be tested on the test bench, and it is impossible to get the results for a while.

Liang Shumei can help Jiang Huijie, Yan Yu can't help at all, it's better to rest and recover some strength.

Yan Yuben just waited on the sofa and gradually fell asleep.

When he woke up, it was already evening outside, and it was dark again, as if he had entered another dark world.

There was food on the coffee table, which should have been delivered by someone else, and it didn't wake him up, and there was no emergency for anyone else.

Liang Shumei and Jiang Huijie were still busy, and when they saw that Yan Yu woke up, Jiang Huijie said: "Let's eat first, I didn't let ......them wake you up."

Yan Yu was a little embarrassed, after all, Liang Shumei was also present, but she still nodded and finished her meal quickly.

"Has there been any progress?"

Jiang Huijie nodded, and shook her head again: "I just screened a few different samples, used the soil samples around the base to compare, and found some different things, but I can't be sure yet, you wait a little longer." ”

Hearing that there was progress, Yan Yu was also a little excited, and where did he dare to rest, so he waited by the side.

Liang Shumei is also "inhumane" when she works seriously, and like Jiang Huijie, after entering the working state, she "doesn't recognize her six relatives".

About half an hour later, Yan Yu planned to go to see the others, but at this time, Liang Shumei picked up the test strip, compared it on the instruction strip, and said to Jiang Huijie: "Look! ”

Yan Yu heard the voice and retracted his steps.

"What's wrong?"

Jiang Huijie checked the analysis results and said with a solemn face: "There is a sample with chlorine exceeding the standard......

"Excessive chlorine?" Yan Yu is not a major, so of course I don't understand what is surprising about this.

But Liang Shumei and Jiang Huijie know the meaning behind it!

"Disinfectants usually contain chlorine, and the smell you smell in hospitals, and some of the smell of tap water, is because of chlorine......"

"That is, he sanitized his shoes? Want to get rid of the traces? Yan Yu was also a little disappointed, because it meant that it was impossible for the murderer to leave more information.

However, Jiang Huijie shook her head: "It shouldn't be, if it's to disinfect shoes, it won't be such a low dose, the biggest possibility is that he has been to a place that has been disinfected." ”

"A place to disinfect?" Yan Yu's thoughts were racing, and a thought hit his heart like thunder and lightning!

"Hospital! He's always been at the base! That's why I'm so confident! He had expected me to gather everyone together! ”

Yan Yu didn't hesitate for a moment, and ran out.

Yu Guofeng and the others didn't dare to sleep, they all gathered together at this time, took out the previous files for analysis, and examined them again, and did not sit still.

"Search the entire base, he might be hiding in the base!" Yan Yu crashed into the office, and everyone became nervous when they heard this!

Because everyone was taken back, and he was on full alert, Yu Guofeng immediately arranged it.

"Don't go out, don't fall into his trap!" Yu Guofeng said this, and left quickly with Hong Dafu and Guan Rui.

When Zhang Gulin and the others heard that the murderer was hiding at the base, they were also nervous.

Half an hour passed, an hour passed, and two hours passed, and Yu Guofeng finally came back a little dejected.

"All searched, and nothing unusual......"

"What about the periphery?" Yan Yu was also a little dignified.

Yu Guofeng shook his head: "The entrances and exits are all sealed, if he is on the periphery, he can't enter, how can you be sure that he is in the base?" ”

"Liang Shumei and Xiaojie found excessive chlorine in the sample, he should have been to the disinfection place, most likely the hospital ......"

Yu Guofeng and the others listened to the analysis, and they didn't dare to relax: "I'll let them search again." ”

But when he walked to the door, he suddenly stopped: "What if he is in his lair, and his lair is also a hospital?" ”

"The murderer is indeed in the hospital, but it doesn't have to be here!" Yan Yu muttered this sentence over and over again, and his face suddenly became ugly!

"Suffered! Dean Qi! Dean Qi! ”

"Dean Qi is still in the city doctor! In the city doctor! ”
