The water quality test data in the notebook is very detailed, and the records on it continue to this day

Chen Xunyi's hand rubbed lightly on the paper of the notebook, and after a while, he raised his hand and wiped his index finger with his thumb.

"What do you see?" Ren Mingxiao walked over and asked.

Chen Xunyi shook his head, "I'm not sure!" He flipped through the notebook to a dozen days ago, and then slowly looked at the data recorded.

If there is a problem with the water quality, a test data must become abnormal!

His gaze wandered over the paper of the notebook, and finally locked on the ammonia nitrogen content.

In the data of this month, the amount of ammonia nitrogen has been increasing, most likely because it is decomposed by some kind of microorganism, he speculated, if that...

Chen Xunyi hung the notebook in its original position, walked to the experimental table, carefully looked for the experimental supplies in front of him, and took out a bottle of container with iodine and mercury chemical formula.

"What are you going to do?"

"A very simple way to test!" Chen Xunyi Mali found out the testing supplies needed from the glass bottles full of chemicals.

He quickly picked out the tools of various chemical experiments from the laboratory table and placed them on the laboratory table.

"You're going to do this?" Ren Mingxiao's eyes widened and she looked at him curiously.

"College extracurricular life did this survey!"

"You know so much!"

"Thank you!" Chen Xunyi turned his head sideways and said with a smile.

Ren Mingxiao looked at the chaotic chemical test equipment on the experimental table in front of her, which was built in an orderly manner to resemble the interior of a chemical factory.

These things are so strange to her, and the nursing profession doesn't understand these things! She shrugged.

Chen Xunyi took the stirring glass rod and slowly stirred it in a spherical container.

Ren Mingxiao took a few steps back, she felt really bored, so she walked towards the gate, wanting to go outside to prevent being discovered.

She stood in the doorway, her eyes looking around, and there was silence around her, no one, like an empty city.

Ren Mingxiao turned his head and saw that Chen Xunyi was still staring intently at the experimental device in front of him, and he looked serious... At that moment, she turned her head, wondering why she had such thoughts.

Davide won't let himself go at all, as long as they don't get divorced, they can't do it at all...

No... I didn't even think about talking to him... These.... Her heart was full of irritability, which made her a little breathless.

Ren Mingxiao turned her head, patted her chest with her hand, and sat on the steps of the door, her head leaning against the door frame, trying to suppress the cranky thoughts in her brain, but thoughts kept pouring out of her brain.

At this moment, her eyes looked at the side of the cement room, the metal water reservoir that was more than 20 meters high, such a high water reservoir, if people fell into it...

Suddenly, a figure appeared on the steps above the metal water reservoir, because the light was not very good, and the distance was too far, she could only see a rough idea, and this was the approximate, which made her whole person panic.

The figure was descending the stairs, and at its speed, it should be five or six minutes before it reached the ground.

Ren Mingxiao didn't think much about it, and immediately jumped up from where she was sitting, ran in, and said in a panic, "This place is not without staff!" Someone is up there, on that shelf made of steel pipes, and someone is going down! ”

Chen Xunyi was still looking at the experiment in front of him intently, he picked up the test tube and shook it, "How long will it take to get here?" ”

"About five or six minutes!"

"Excellent! Enough time! Chen Xunyi poured the things in his hand into another round glass bottle, and he banged on the experimental table with his hand, muttering in his mouth, "Quick!" Fast! Fast! ”

Ren Mingxiao walked to the door again, her eyes staring at the figure who walked down the steps, what could be done to hold that person.

"How long do you have left?"

"Soon!" Chen Xunyi carefully picked up the test tube and was busy on the experimental table, and after a while, he missed and dropped the test tube in his hand on the experimental table, and the solid substance inside fell out.

Chen Xunyi leaned back suddenly, "Horse's!" Worst! ”

"Forget it! That staff member will be downstairs soon! ”

"No! The last step! Chen Xunyi's brows furrowed tightly, he pulled up his sleeves, directly abandoned the tools, and started working on the experimental table with his hands.

Although she doesn't know much about chemical experiments, Ren Mingxiao knows that some things can easily cause unnecessary damage to your body if you move without any protective measures!

"Is that okay?"

"It's fine!" Chen Xunyi gritted his teeth, finished the rest of the experiment, pointed to the door, and hurriedly brought me the notebook.

Ren Mingxiao walked over and threw the notebook to Chen Xunyi, he quickly tore off two pieces of paper, and then wrote something on them, and threw the notebook back to her.

"Won't you give the pen back?"

"It's still useful! I'll borrow it first. Chen Xunyi stuffed the pen back into his pocket, quickly dismantled the experimental equipment, and put them back in place as much as possible.

"Gone!" He walked towards the door, "Don't answer anyone's words, just think we have something urgent to do." ”

"Got it!" Ren Mingxiao followed.

Not far from the concrete bungalow, the figure on the steps shouted at them, "Hey! Wait a minute! ”

Worst! We're going to be discovered! Ren Mingxiao thought to herself.

Chen Xunyi stopped, turned to the side slightly, and said to Ren Mingxiao, "Don't be nervous! Maybe he won't recognize us! ”

"Unless it's blind, it's so obvious, we...

Chen Xunyi turned around, raised his hand towards the staff who walked down the steps, and said hello.

"Is there something wrong?"

"Why did you come out of the room?" The staff member in the blue overalls came over!

"We!" Chen Xunyi paused, "Because I received an order for a temporary test, I need to go there to see the water quality data of the past few days!" ”

The staff member had a suspicious look on his face as he looked at the two of them.

Chen Xunyi was in a hurry, he put his hand on the work card, and covered the portrait on the work with his hand, "We are from the experimental department!" ”

The staff sighed and handed the folder in his hand to the past, "The latest inspection data is here!" You'd better go up and see for yourself! ”

Chen Xunyi stretched out his hand to take the folder, and he nodded with a smile, "Thank you!" That's what I'm thinking! ”
