The carbonate crisis first appeared in Chapter 9. "Carbonate Crisis" mainly tells the story of high school student Chi Lie and class teacher Yan Hui's youth campus.

In fact, when I first saw the name, I thought it was a chemistry teacher, but after reading it, I realized that I just thought too much.

"Carbonate crisis" has several meanings in my understanding.

One is that they met in summer, and the article also mentioned iced coke many times.

The second is to describe the feelings of two people, just like carbonated drinks, there will be uncontrollable reactions when touched.
