Chapter 758: School rules

I don't know how the night passed. In short, when Mu Qilian woke up in the morning, he was refreshed.
Was awakened by the rules.
[The exam is about to start, please arrive at the exam room within an hour, now please go to the cafeteria for breakfast. 】
Mu Qilian turned over and sat up, stretched out a big laziness, and yawned: "Hey, I remember I was scared last night. I don't know when I fell asleep. Did the ghost knock on the door? We should not have won the prize, right?"
Song Yanqing and Zong Yu turned their heads and looked at him with unexplainable words.
Qiao Jin simply said: "Knock it, you are asleep, I didn't hear it."
Mu Qi shook again and again: "So you heard?"
Qiao Jin: "As long as you don't react, it's okay. Our door lock was broken yesterday. It should be able to push the door in directly, but you asked the uncle for the lock, and it didn't open it."
Mu Qilian was immediately extremely proud: "I just said it!"
He is so smart, how could he be fooled.
There is one more thing to get up, and that is to wash.
Fortunately, some basic items are prepared in the dormitory. Although they are very simple, they can barely brush their teeth and wash their faces.
They went to the cafeteria to have breakfast this time, and the students from the other examination rooms on the way came out together. Qiao Jin counted, and there were a lot of people alone.
She raised her eyebrows. It seemed that they were the lucky ones to be picked last night, just because they didn't open the door to avoid a disaster.
However, many people still have dark circles under their eyes, and even now they are still a little scared, and the psychological torture of the whole night is not good.
But obviously, if the exam is over today, the lucky ones who are picked tonight will probably not be so lucky.
The breakfast made in the cafeteria this morning was a bit more normal. There was a bowl of steamed buns and a bowl of gruel.
Anyhow, I can eat, but I can't be so picky.
After eating, there was another delay, and it was almost time to go to the exam room to continue the exam.
Today's monitoring teacher is also the one I saw yesterday morning. She saw Song Yanqing with a very happy expression. She posted the papers. When Qiao Jin saw today's question, she was a little surprised.
The topic has changed.
Which dormitory door did the ghost student knock on last night? 25 points
②How many times did the ghost student knock on the door? 25 points
③The ghost student needs to take away one person every night. It failed to complete the task yesterday and was already a bit angry. So it vowed to take away twice as many people tonight, so how many people should it take away? 50 points
Very easy to answer.
But the third question is an obvious trap question.
And occupy the highest score, if this question is answered incorrectly, basically GG.
The ghost student takes one away every night, it failed last night and vowed to double it tonight. If you just take away the person X double that night, then there won't be one more question.
Therefore, for the second night, it must count the people from the first night, which means that it will take away two people tonight, and double that is 4.
The appetite is really big.
Qiao Jin gave a tut and quickly filled in three questions.
All three things are right, full marks.
The topic was really not difficult. She turned her head and saw that the teacher had already come over with a smile, and said: "Today's topic is simple, and there are no small red flowers for full marks."
Qiao Jin: "..."
Is it still possible to make a difference in this way?
Song Yanqing also answered the question correctly, with the same score. He stood up, cast a look at Qiao Jin, and the two walked out of the classroom together.
The goal is the school rules column.
