In the open space of the testing station, there are many guards patrolling there, and in front of many buildings, guards equipped with electric batons are arranged to maintain order.

Chen Xunyi underestimated the number of guards here, leaned back, and said in a helpless tone, "We are really here to do the test!" ”

The guard who was watching them picked up the electric baton and said, "Shut up!" ”

Chen Xunyi was still yelling and explaining for himself, and at the same time took a chance, turned his head and whispered to Ren Mingxiao, "Be ready to run away at any time." ”

The door to the hut was opened, and the guard looked at them.

"Run!" Chen Xunyi whispered and took two steps back.

The guard raised his hand, "Let them in, there is indeed a test to be done!" ”

Chen Xunyi, who was already about to run out, leaned forward suddenly, "I'll say it!" ”

He and Ren Mingxiao walked in.

"Don't look behind!" Chen Xunyi reminded that his footsteps were walking fast, for fear that the guards would stop them again.

"Where are we going now?"

"I don't know! Anyway, you can't go to the experimental department written on the work card first! There must be a lot of people over there who know the person on the work card! ”

"But what if we're going to the Experiment Department?"

"Then we're out of luck!"

They walked into the building, trying to get as close to the wall as possible so as not to attract the attention of others, and since the work card they were using was a staff member of the testing institute, they could not ask where the water quality was being tested.

He and Ren Mingxiao could only move around, pretending to be staff members who were in a hurry to run errands, always paying attention to their surroundings.

It took a lot of effort for them to find the area where the water quality was tested was at the back of the testing station.

There were several metal cisterns of various sizes, but very large for them, and there was a special section of pipes that connected to the ground in a row of flat concrete rooms, and he saw one of them without a gate, in which a large testing machine was placed, and various tools for filtration and experimentation.

They walked towards the cement room, and when they passed by the metal pool, they saw the messy pipes on the edge of the metal reservoir, and couldn't help but sigh at the complexity of this water purification device.

"Where does all the water we use come from?" Ren Mingxiao looked up at the metal pool as she walked.

"Yes! A large amount of water enters this metal pool through the pipes, and after a period of time the sediment sinks to the bottom, the upper water flows to the other metal pools for filtration and purification, and the lower water is chemically treated and supplied to the industrial area! ”

Chen Xunyi stopped, he hid behind the steel bar, glanced at the cement room on the side a few times, and after confirming that it was safe, he stepped out again and walked towards the front.

From the outside, it seemed to be quite easy to get inside, but what made him feel even more strange was that this operation was a bit hasty for them! But from entering the testing center to now, walking to the cement room, everything seems quite relaxed. In front of me, the door was open, and there was no defense at all.

Chen Xunyi stopped, "Strange? He looked around as he walked.

"What's wrong?"

"Not even a single guard?"

"This is their territory, there is no need to arrange so many guards!"

"But before, when we came in, we saw a lot of police patrolling there!"

They walked around to the side of the cement room, clinging to the wall, and slowly approached the window of the other cement room, and looked inside, where they saw a row of experimental tables, all of which were used to test water quality.

Chen Xunyi slowly bent down, bypassed the wall, stood on the side of the door of the cement room, and looked inside, the scene in the room appeared in his eyes, a room with many complex detection tools, and a computer in the middle.

He didn't see any figure in the room, so in order to ensure safety, he hid on the side of the door, and looked inside for a long time, and only after making sure that no one was there, did he enter through the main entrance.

It's just so weird! Forget it if there are no guards, not even a staff? His hand rubbed gently on the lab table.

Chen Xunyi stood in front of the computer and tried to enter the computer, but the system was locked and a password was needed!

He looked around, and there was no one who still needed a password?

Ren Mingxiao stood at the end of the experimental table, she leaned down and looked at the row of beakers on the table, all containing half a glass of water.

"Come here and have a look!" She stretched out her hand and shouted!

Chen Xunyi left in front of the computer, he has been thinking about how to get into the computer system, there will be a record on this computer!

"What's wrong!" He walked up and saw a piece of paper on the lab table with labels for various water quality tests!

"Look at the dates on these beakers!"

Chen Xunyi leaned down and looked at the date of the row of beakers, "It seems that the beakers in these beakers should be test samples, but there is no time mark behind this, and the last time mark is a few days ago!" ”

He picked up the beaker and placed it on top of his head, and looked up at the bottom of the beaker, the water inside looked quite clear, and there was not even a single dice of impurities.

Odd! Samples for all types of water testing should include sewage, but how can the water look so clean? After processing and filtration, what else is tested?

He put down the beaker and kept picking up the other beakers on the lab table, and the results were all the same.

Chen Xunyi put down the beaker, turned around and walked to the computer, he squatted down and tried the ordinary administrator password on the computer!

While! The computer made a forbidden sound for the wrong password!

After trying a few sets of passwords to no avail, he pressed his hand to his forehead, and it seemed that there was really no way to open it!

If that's the case, it seems that you can only go to the experimental department on your work card! Chen Xunyi picked up the work card hanging around his neck and looked at it.

"Let's go!" Chen Xunyi moved his mouth towards Ren Mingxiao!

"That's it?"

"Yes! Nothing? ”

"What about the date on the beaker?"

"Not so clear! Now, we're going to have to try our luck in the lab! ”

"Wait a minute! You said that such words, we are not easily exposed? Ren Mingxiao said.

"yes!" Chen Xunyi walked towards the door, "But there are no clues here!" We are simply useless here. ”

When Chen Xunyi stepped out of the door with half a foot, something appeared in his sight, he immediately retracted his foot, took half a step back, and picked up the notebook hanging on the wall next to the door!

He flipped through it casually and saw that it detailed a month's worth of water quality testing data. ：，，，
