v2 Chapter 612： Old father smile (1/2)

To be honest, Qin Luo was very pleased, and his face was like an old father's smile, because he saw so many students who were working hard, which was the best compliment for him as a teacher.

”Classmate, how do you feel?” Qin Luo smiled as he looked at a student in the front row who was struggling to write.

”We, Master Yan, don't have difficult final exam papers...” As he spoke, the tip of the pen was beating quickly, and after ten seconds, he had finished all the multiple-choice questions.

”...” Qin Luo's mouth twitched, and he felt speechless.

”Classmate, are you sure you didn't do the calculations carefully?” Qin Luo kindly reminded.

”No need, we Master Yan won't have a difficult final paper...”

Raise the pen again and write quickly...

After ten seconds, the fill-in-the-blank question comes to an end.

Ah……

Qin Luo felt that it was not good for him to go to school, and encountered a scumbag.

Ever since, Qin Luo turned his gaze and fell on a boy with eyes.

With short hair and black bags under her eyes, she is a student with excellent academic performance.

”Classmates feel...” However, before Qin Luo finished speaking, the boy had already moved.

I saw him tear off four small pieces of paper of equal size from the draft paper.

Does he want to solve the problem with model proof method? Although this method is a waste of time, it is also a method when it is really impossible to answer.

But in the next second, Qin Luo's eyes widened.

I saw that the other party wrote four letters on the paper: A, B, C, D, and then folded the paper in half into small squares of the same size.

Draw one, fill in one.

Draw one, fill in one.

”...” Seeing the scene in front of him, Qin Luo felt a sense of deja vu.

Once, when he was in the examination room, he was the same as the opponent.

What kind of **** model verification method, this is the legendary metaphysical problem solving method.
