"What's happened to us?"

Xiao Ning didn't react for a moment and asked a stupid question.

A Yuan, the shop assistant who was wiping the shelves with a rag, reminded with a smile, "Brother Ning, you forgot that you have a pop quiz today."

As soon as these words were spoken, Xiao Ding and the others became despairing.

Yes, the weekly pop quiz is today.

When they thought of the old man's angry roar every time they failed the quiz and his sister-in-law's ruler, the three of them shuddered.

"Is it too late for us to go and ask A Miao and the others for help?"

"What do you think?"

The voice coming from behind was gentle and smiling, which made people feel particularly kind and warm.

However, Xiao Ding and the others now only felt a biting chill running from their tail vertebrae straight to the top of their heads, and their hair almost stood on end.

My sister-in-law is angry.

Still very angry.

"Sister-in-law, sister-in-law."

"Don't call me sister-in-law. I don't have a stupid brother-in-law like you."

It would have been fine if he hadn't shouted, but once he did, Jian Yuelan wished she would explode in front of them.

She said angrily, "I accept the fact that I fail every time. Can you guys try harder? If you drive away such a good teacher like the old man, you will have no choice but to spend money to go to night school."

At this point, she looked at them with suspicion, "Or do you want to spend money to go to night school?"

"I do want to go to night school, but not now."

Xiao Ding's expression turned serious. "Our current level is not good enough to attend night school. Going there would be a waste of money. Don't worry, sister-in-law. We will definitely study hard with the old man."

"But you know, IQ..."

He nodded his head and said as if he was about to cry, "There are deviations, sister-in-law. We really studied hard, but there is nothing we can do if we forget what we have learned."

I can’t remember it, I really can’t remember it.

Especially when it comes to speaking skills, the mouth always speaks faster than the brain.

Then there is mathematics, such as the cube difference formula, the complex integration formula, the summation formula of natural number powers, etc., which really give them a headache and make them wish they could chop off their heads and replace them with new ones.
