That's a cleaner.

He has a hat on his head, and his face is basically invisible from the video.He was holding a bucket in his hand, and there were some cleaning tools and a large bottle of detergent in the bucket.

Nan Junliang stared at him for a while, but didn't see anything.After he went up to the top floor, he came down after a while, and after a while, Lin Xue went upstairs.

But the appearance of the cleaner kept wandering in Nan Junliang's mind, which reminded him of the smell similar to that of cleaning agent or fragrance in the replay.

He asked Li Qingchi to replay the part of the cleaner again, and the more he watched it, the more doubtful it became.The hat is kept low, and it’s okay to keep your head down so you don’t get a picture of your face. It’s just a short time to go up and down the stairs. During this process, the plastic bucket is not even filled with water. What did he do up there?

Nan Junliang asked: "Is there a cleaner on the top floor of our school?"

Li Qingchi was stumped by this question.

"Well... maybe there is."

He is the president of the student council, but he has no control over the management and work arrangements of the janitors, so the details are really unclear.

"You think there's something wrong with this cleaner?"

Nan Junliang said: "I'm not sure. I want to confirm a little bit. Can you see which brand of detergent is in his bucket?"

His focus is a bit odd.However, Li Qingchi still made a careful distinction, but he didn't usually look like someone who needed to do housework by himself, so he didn't recognize him for a long time.

But this is not a problem for Li Qingchi.He took a random screenshot, put it on the search engine for a comparison search, and quickly found the brand of the cleaner.Because it is a big brand, Yan Ximin went out and ordered the servant to buy a bottle from a nearby supermarket.

Nan Junliang took advantage of the opportunity to go to the bathroom to replay the live video.This time, he repeatedly inspected every corner of the roof, especially the outer edge of the railing. He sniffed it almost every few steps, and just stuck out his tongue to lick it.

However, Nan Junliang has been a beautiful boy since he was a child. The first love of girls is a male god, and he is a bit of an idol. Even if no one sees him, he can't do this kind of thing for the time being.

When he sniffed the cleaning agent, he remembered the smell as best he could, and determined the extent of its presence.On the day of the live broadcast, he noticed that the wind on the roof was very strong, and he confirmed this again at this time.Because of the strong wind, the smell disappeared quickly, and basically there was only a trace of residue.Except for the part where Lin Xue jumped down, Nan Junliang couldn't smell the smell on the other edge.

After buying the cleaner, Nan Junliang and others squeezed into the bathroom of his room to test it.The bathroom of the Yan family is already larger than the family bathrooms of other families, but it still seems a bit crowded with so many people.

The little loli Nan Yilan still wanted to squeeze in, and she must stick to her brother. After being reprimanded by Nan Junliang, she curled her lips and showed an aggrieved expression, and hid behind the door frame.

It's rare that the little crying bag didn't cry, but Yan Ximin couldn't stand it anymore, and said to Nan Junliang, "You are too fierce to your sister, aren't you?"

Nan Junliang rubbed his hair, thought for a while with an innocent face, and felt that what Yan Ximin said seemed to be correct, so he avoided everyone and walked to the door, squatted down beside Nan Yilan, and said: "I have something to do now, tonight Play with you again, you can watch TV obediently now, or play with grandma."

Nan Yilan said: "Then brother plays with me at night with dolls!"

Nan Junliang: "...Okay." He accepted the condition with difficulty.

During this process, Yan Ximin kept looking at him, and his heart moved slightly.If I have to say it, Nan Junliang's personality is no different from that of ordinary boys except that he looks a little foul.

But it is the "no big difference" personality, occasionally revealing some details that are slightly different from ordinary boys, which are particularly attractive to the eye.Nan Junliang's character is quite casual, but in this casualness, there is a bit of wonderful softness that needs to be digged a little to see, which has become his capital to attract girls besides appearance.

Yan Ximin couldn't help but wonder if his aunt, whom he had never masked, had a similar personality.

After Nan Junliang sent the little girl away, he turned around, opened the bottle of detergent and sniffed it.

Li Qingchi was a little curious about what he could sniff out.

After sniffing Nan Junliang, he was basically sure that it was the same smell he had smelled on the roof before.

He said, "That's right, it's this taste."

Li Qingchi asked: "Is there any problem with the smell of detergent?"

Nan Junliang said: "After Lin Xue's accident, Lu Fanqing and I went up to the top floor to have a look. At that time, I smelled the cleaner."

Yan Ximin said disapprovingly: "...doesn't the smell of cleaning agents all smell the same?"

Nan Junliang said: "...It's far away. Do you smell the same perfume?"

Yan Ximin: "..."

Nan Junliang was right.

He became a little annoyed and said, "I'm not a girl. Only sissies are interested in things like perfume!"

Nan Junliang suddenly raised his head, moved a little closer, and fixed his eyes on him.

Nan Junliang's eyes are very beautiful.Generally speaking, children's eyes are very clear, and when they grow up, as their eye habits deteriorate, they will be dulled to varying degrees, but Nan Junliang's eyes are still clearer than many of his peers at this time. , coupled with his emotionless expression, has a sense of beauty and horror like a doll in a horror movie.

Although Yan Ximin wouldn't be frightened, she was a little scared in an instant.

He said dryly: "What do you want? Why do you look at me like that?"

Nan Junliang said: "For something that I don't understand, I deliberately belittle and attack it. I feel very tasteless, second cousin!"

Yan Ximin: "..."

He said angrily: "I want you to take care of it!"

Nan Junliang ignored him, but continued to say: "My nose is quite sharp, and I should not be mistaken for this smell. At that time, the typhoon was very windy. If it wasn't for the smell that had just left behind, it would have been impossible to be recognized. I smell it. And according to the monitoring, at least this is the only clue we have found so far that leaves a similar smell."

"I'm going to experiment with how well this cleanser glides on," he says.

He asked people to move some distance away, and then poured the cleaner evenly on the bathroom tiles.The roof of the school itself is used for rest, and the decoration and beautification are very good. The roof and the floor are all covered with white tiles that look very similar to the bathroom floor, so the experiment here is also somewhat reductive.

After Nan Junliang poured the detergent down, he didn't step on it immediately, but observed carefully first.This kind of cleaner is very pure, transparent and off-white, and it is not obvious when it is poured on the white tiles. You have to look hard to see a little trace.

But even so, Nan Junliang was not satisfied with the effect.He asked someone to turn on the light, and then turned on the flashlight function of the mobile phone, directly shining on the location of the liquid.The intensity of this light is basically closer to the brightness of the sun at noon that day. As Nan Junliang expected, under this intensity of light, the naked eye's recognition of tiles and liquids is indeed reduced, and the liquid is basically not detectable. The presence.

Nan Junliang asked Li Qingchi to take a picture of the liquid on the ground under this light.

Then he stepped on it.

The degree of lubrication of the cleaning fluid was higher than Nan Junliang expected, and the floor itself was made of tiles, Nan Junliang almost slipped the moment he stood on it, and the preparation in advance was of no use at all—he avoided Qin with all his strength. Lily, who didn't want to be an abrupt girl, bumped into Li Qingchi's body.

Almost at the same time, Yan Ximin also collided with Li Qingchi.

He also seemed to want to pick up Nan Junliang.

Although his head was protected, Nan Junliang still sat down on the ground with his buttocks. The strength was not small, and he inevitably gasped.As a result, he took a look and found that the entire barrage had exploded.

[The anchor's charm is boundless! 】

[This atmosphere is so exciting! 】

[The girl's expression is really indescribable. 】

Nan Junliang instinctively looked at Qin Lili, and found that she was frowning and looking behind her with a very complicated expression.Nan Junliang turned back to look at Yan Ximin and Li Qingchi again, but saw nothing.

Li Qingchi asked, "Are you okay?"

Nan Junliang: "...It's okay. But let me take it easy."

He waited a while to get up, and then joined the rest of the experiment.They tested the volatility of the cleaning solution and found that the cleaning solution would volatilize in about fifteen to twenty minutes to the point where it could not be detected by the naked eye.If it is exposed to direct sunlight, it may be faster.

To confirm this, they did another experiment under sunlight.

Li Qingchi is very useful as a family member of the police, and Nan Junliang can get a lot of news through him.After discussion, they carried out a division of labor and cooperation. Among them, Yan Ximin went to inquire about the school's arrangements for the cleaning work in the school, Qin Lili went to have a deep talk with Lin's father, and persuaded the other party to further investigate the truth of Lin Xue's death, and Li Qingchi went to his uncle. Have them verify the identity of the cleaners.

After class on Monday morning, Lu Fanqing still wanted to talk to Nan Junliang, but Yan Ximin pulled Nan Junliang away when he came up, and said, "Guess what I found? There is no cleaner on the top floor of our school." The open and easy-to-clean places, such as the playground and the roof, are generally arranged for students from various classes to clean.”

"Moreover, the most important thing is that the cleaners used in our school are uniformly ordered, and we have always used another brand, which is green cleaners, and the outer packaging is completely different. The cleaners are green, and it will be very dangerous to pour them on the ground. conspicuous."
