When mu Shinian finished breakfast and went out, he had been late for more than two hours.

She took a taxi to school. She thought she would be blamed by the teacher, but nothing happened.

She sat back in her seat and thought silently. Was it because her grades were really bad, so the teacher was angry and turned a blind eye to her?

Ye Ling secretly turned around and whispered, "if the teacher asks, you say you sent a pregnant woman to the hospital on the way."

“……”

Mu Shinian immediately reflected what was going on.

When she pulled the corner of her lips, her voice was buried very low: "thank you."

"You're welcome." Ye Ling replied very forthright, turned around again and listened carefully.

Mu Shinian stared at the final axis geometry problem on the blackboard, took out a piece of paper, added two auxiliary lines, and then listed two formulas, simply substituted them in, and worked out the final answer.

It's too simple.

Mu Shinian is biting her pen. She still has one semester. She can relax by loading the learning slag for another semester.

Being distracted, a piece of chalk suddenly whizzed towards her.

Mu Shinian unbiased opened his head and avoided the chalk head.

The teacher didn't hit anyone and sneered: "lowering the average score of the whole class will not only make the students blush, but also make our teacher lose face. This will make us analyze the paper. What are you distracted from?"

Mu Shinian glanced at the teacher and said nothing.

The teacher was even more angry when he saw her as a ruffian: "go out if you don't want to listen to the class!"

Mu Shinian's class has always been such a state.

She doesn't necessarily listen much, but she never gets in the way of others.

She was in this one third of an acre, either distracted or in a daze.

The teacher came to replace the class for a period of time. It is estimated that it is rare to lead the key class. As a result, his grades suffered Waterloo, so he blamed mu Shinian for his fault.

Mu Shinian stood up slowly in full view of the public: "you can go out and give me a reason."

"You don't listen to the class. Do you have a reason?" The teacher asked angrily, and the fire was about to burst out in his eyes.

Mu Shi read his lips and looked back at the title on the blackboard: "that question?"

The teacher sneered: "the whole class is thinking about how to answer, how can you? So don't listen?"

The smell of the fire medicine is getting stronger and stronger.

Ye Ling couldn't help grabbing her sleeve; "When you're ready, don't say it."

Mu Shinian grabbed Ye Ling's hand, stared at the topic, and slowly opened his mouth: "well, yes, I will."

The whole class was stunned and laughed.

The teacher's face turned blue with anger: "be quiet!"

After roaring, she sneered: "you will. You haven't even got the basic score. How dare you say you will?"

Too simple.

Lazy thinking.

Mu Shinian thought in his mind, suddenly raised his hand and pointed to the two already drawn auxiliary lines: "wipe off the two auxiliary lines and replace AD and FH."

The teacher didn't react.

But other students in the class tried to draw two strokes, and then seemed to find the new world: "shit, really!"

The sound was very small, but it was like a bomb that blew up the whole class.

The teacher also turned around, picked up the chalk, tried to draw twice, and then looked silly.

She just drew the auxiliary lines for a long time and used a pile of formulas without a clue. These two simple and rough auxiliary lines were never involved in her previous teaching experience
