The morning's classes were more efficient than expected, Mr. Bomb didn't mess around, Miss Sleepy didn't hibernate, and even the teacher's class was funnier than usual.

Everything seems to be on track.

Jian Han propped his chin with his hand and watched with great interest as the chemistry teacher demonstrated the thermite reaction experiment on the podium.

The polished magnesium strip burns violently, emitting a dazzling light and a large amount of heat energy, so that the aluminum powder and iron oxide powder in the paper funnel undergo a violent redox reaction at high temperature, and the resulting liquid beads in a red-hot state burn through the funnel, fall on the fine sand in the evaporation dish, and become a black solid after cooling.

The reaction was only a matter of a split second from the beginning to the end, and there was a burst of cheers from the audience, and the teacher wiped the sweat from his forehead, and the expression on his face was much more relaxed.

Ruan Zhizhou was so noisy that he raised his head from the crook of his arm, the itching sensation of the allergic skin on his arm made him very irritable, and there was a deep tiredness lingering between his eyebrows, but as far as his eyes could see, he only caught a cloud of smoke that was about to dissipate, and his expression couldn't help but be a little dazed.

"What are they shouting?" He rubbed his eyes, turned his head and asked Jian Handao.

"It's just an interesting experiment." Jian Han quickly retracted his gaze, pausing slightly as the afterglow swept over his right jaw, a faint smile on his lips.

“…… Fuss. Ruan Zhizhou half-covered his mouth with his hand and yawned.

"You didn't get a good night's rest last night? Dark circles are heavy. Jian Han hung her head and asked while taking notes.

Ruan Zhizhou lay back on the desk, his left face resting on his right arm, looking at her directly, his voice sounding a little hoarse, "It's not bad." ”

Few people ask him if he is well-rested, most of the time, as long as he doesn't get sick, he is just an insignificant existence.

After realizing this, he never underestimated any kindness again. It's not about being vulnerable, it's about being cautiously strong, because you don't want to be pathetic, so you crave love more than anyone else, and you need to be illuminated more than anyone else.

Suddenly, his ears seemed to be rubbed by sandpaper, indirectly polishing away a thin layer of estrangement in his heart, Jian Han clenched the pen in his hand, and his writing speed slowed down.

She turned her head to look at him, Qingli's eyebrows were slightly twisted, and in the next second, she persuaded softly: "The midterm exam is coming up this Thursday, you should review well." ”

Ruan Zhizhou stared at her "Five-Year College Entrance Examination Three-Year Simulation" for a while, and silently looked away, "It's easy to say, it's easy to say......"

Seeing him resist like this, Jian Han moved his lips, but for some reason, he never said the sentence "I have to rearrange my seat after the midterm exam".

High school life and learning always revolve around the two states of orderliness and chaos, and everyone learns to choose and wait in the repetitive steps, discard the unimportant, and hunt the valuable.

But there is an unavoidable time, divided by fate into unexpected accidents, which cannot be guessed or forgotten.

"Hey, Shen Yuqing, let me ask you a chemistry question from junior high school." Wei Qiao grinned and poked his tablemate's elbow.

"What?" Shen Yuqing had just finished a calculation problem with the principle of conservation of electrons, and asked in a good mood.

"What was phosphorus pentoxide before it was oxidized?" Wei Qiao asked.

"Are you stupid......" Shen Yuqing glanced at him strangely, and blurted out, "Elemental phosphorus!" ”

"Wrong!" Wei Qiao shook his head with a serious expression.

"Impossible!" Shen Yuqing sneered.

"It's 520!" After speaking, Wei Qiao returned to his smiling appearance.

Shen Yuqing looked at him blankly, the corners of his mouth twitched, and he raised his slap high and said, "...... I want to wash you. ”

Hearing the movement, Jian Han and Ruan Zhizhou turned their heads at the same time, one laughed uncontrollably, and the other had an extremely disgusted expression.

How can you be so gay......
