Soon Yuan Youwei knew.

After a summer of precipitation, and the impact of cleaning the classroom just now, the dust on the glass is very thick.

Yuan Youwei wiped the first glass, and after wiping it once, the rag was dirty.

Throwing the rag down into the bucket, Yuan Lijia hurriedly cleaned it, and after cleaning it, she handed it to Yuan Youwei, who was still climbing the window guardrail.

After wiping it a few times, the water in the bucket was already muddy.

Yuan Lijia carried a bucket to change the water, and Yuan Youwei came down from the window railing first.

As soon as she stood firm, Bai Xiushan went and returned.

"Youwei, Ding Ya asked me to go to the teacher's office to help, and you can wipe the glass underneath."

It's not a big deal, it's just a matter of effort.

Yuan didn't feel embarrassed, but there was one thing she had to ask first.

So she asked, "Who's the window score for later?" ”

It's not that she's a villain, but if she cleans the window, if the score of the evaluation is not what Bai Xiushan is satisfied with, then who is to blame?

What if it affects the rating of the upper window?

Bai Xiushan took such a trip, and she was able to make Ding Ya, who had always been "iron-faced and selfless", change her task arrangement.

Yuan Youwei had to think about it more.

God knows, this one didn't happen at all in my previous life.

For unexpected things, Yuan has to be cautious.

Although she is not highly educated, she also knows the "butterfly effect".

What's more, according to Bai Xiushan's character, this matter may definitely extend to more "accidental" things.

Bai Xiushan was stunned for a moment, obviously she didn't expect Yuan Youwei to ask such a question, "Then I'll ask." ”

Yuan shrugged slightly, reached out and wiped the lower window glass, and the dark fingertips told her that the task was still quite difficult.

She took a step back and looked at her classmates who were busy climbing up and down the other windows, wondering if everyone had only two or three sides of glass.

With such a heavy dust, it is too normal to spend a morning to wipe it clean and calculate the speed of water change.

Yuan Lijia returned, only half a bucket of water was swaying, and the rags on her hands were cleaned.

Yuan Youwei took the rag, looked at the person next to Yuan Lijia, and then looked at the person in the adjacent window.

"Lijia, you and Lin Hong take turns carrying water."

Lin Hong, who was standing next to Yuan Lijia, looked over when she heard this, "What? ”

Yuan Youwei said, "When you go to change the water, I'm waiting here, it's a waste of time." ”

Yuan Lijia looked at her suspiciously, "Anyway, there's a morning." ”

Shi Keqing, who was rubbing the adjacent window, stopped moving, climbed the window and lowered her head to look at her.

Yuan Youwei explained, "When Lin Hong went to carry water, the squad leader and I used the water brought by Lijia, and Lijia, you are responsible for helping me and the squad leader clean the rags." When Lin Hong comes back, you go to change the water and let Lin Hong clean the rag. This way, you can save more time, and you don't have to rush to carry water. ”

The other three were dumbfounded.

And this kind of operation?

Yuan was slightly helpless.

There was no way, this group of children was shackled by their inherent thinking.

The long-term "one cloth and one bucket" cooperation method, as well as the limitations of the scoring mechanism, made everyone not think of a more time-saving and labor-saving way, but only knew to work hard.

Yuan Youwei didn't want to climb down from the window guardrail when Yuan Lijia went to fetch water, not only did the danger increase, but-

She looked at the ash marks on her clothes, and even if she was careful, she would inevitably get some dust.

Seeing that the three of them were still stupid, Yuan urged slightly, "How is it?" If so, let's get started now. It just so happened that Lijia came back, and the squad leader and I used this bucket of water, and now Lin Hong is going to change the water. ”

Yuan Lijia has always been simple-minded, and nodded directly.

Lin Hong looked at Shi Keqing, "Squad leader......"

Shi Keqing nodded, "Just do what you say." ”

Yuan exhaled slightly, took the rag handed over by Yuan Lijia, and climbed up to the window again.

Seeing this, Lin Hong hurriedly took Shi Keqing's dirty rag, cleaned it and returned it to her, and carried the bucket to change the water by herself.

Yuan Lijia, who was left, added Shi Keqing to the person who was watching.
