The people Gu Linmo asked to install the air conditioner were very efficient.

However, it was fully installed within a short morning class time. All the students cheered happily when they felt the cool breeze from the air conditioner again.

Moreover, this air conditioner is compact and installed on the ceiling. It has strong wind power and a wide diffusion area, so the entire classroom can be blown. Even students sitting in the back will not feel cold. It is simply perfect!

"The school is so generous this time. This air conditioner is not cheap. I heard that it has been installed in grades 7 to 9. What a big deal!"

Gu An held his head high, he already knew that this must have been donated by his father, but he kept it to himself, trying to hide the credit and achievement.

Oh...why am I so low-key?

If Mr. Gu knew what he was thinking, he would definitely slap him on the head.

I gave you face by making the air conditioner look like it was donated by you.

Nuannuan also guessed it, but she really didn't expect that instead of asking someone to repair the air conditioner, her father directly replaced their air conditioner, and replaced so many of them!

I feel warm inside, but... Dad is a bit of a spendthrift.

Putting away this subtle feeling, Nuannuan smiled with her eyebrows curved, and was already thinking about buying some gifts for her family after school.

But before they could be happy for long, what was coming finally came.

The four people who skipped classes yesterday were called to the homeroom teacher's office.

Old Hu blew his beard and glared at the four people. The dean of studies next to him, nicknamed Bald Qiang, also stared at them closely.

"It's really lawless. Fortunately, I recognized Gu An with my sharp eyes. Otherwise, I would have to check every classroom one by one!"

Gu An——"…" There's no need to be so persistent.

"As students, is skipping classes what you are supposed to do? You don't act like students at all..."

The Dean of Studies turned on the Tang Monk mode and spoke incessantly at length. Not to mention Gu An and Huo Changfeng, even Nuan Nuan was dazed by his nagging.

But she still gave face to the dean of studies and forced herself to keep her big eyes open and look like she was listening attentively.

Gu An next to me...was almost falling asleep while standing.

"Have you remembered everything? Before school is over this afternoon, everyone must write a self-review for me. It must be sincere and you must know where you went wrong. You are not allowed to copy some self-reviews from the Internet. I have a pair of sharp eyes. If I find out, then... you have to write two new self-reviews for me!"

The four students nodded obediently. Finally, the dean had enough of the lecture and left with his health tea in satisfaction.

After sending them away, Teacher Hu came back and glared at them.

"Gu An, it's fine if you're shameless enough to skip class, but why did you bring your sister along?"

Gu Nuannuan is such a well-behaved and talented student. He must keep a close eye on her and not let her be led astray by an unreliable brother.

Nuan Nuan raised her hand and took the initiative to admit her mistake - "Teacher, we all know that I was wrong. I was the one who complained that the classroom was too hot, and my brother was concerned about me and was afraid that I would get heatstroke, so he took me to the milk tea shop to use the air conditioning."

Gu An stiffened his neck - "I was the one who took my sister out, come at me if you have anything to say, I will be a good man again in thirty years!"

After saying that, he was hit by a piece of chalk from his head teacher: "You are a hero, but go be your bear!"

It's really stupid.

Nuan Nuan covered her brother's mouth - "Teacher, your brother's brain is damaged by the heat, he is talking nonsense."

Huo Changfeng and Li Jingshu nodded vigorously beside them.

Li Jingshu laughed - "Old Hu, let's not bother with that middle school boy, he has a problem with his brain!"

Huo Changfeng——"We were wrong. We need to go back and write a self-reflection."

Teacher Hu waved his hands - "Roll, roll, roll, out of sight, out of mind."

They were not punished any further.

After all... they are all experienced people. They are just skipping classes. A simple teaching will do. They are just a group of kids without any bad intentions.

Gu An was quite experienced in writing self-reviews. Huo Changfeng had also written quite a few. He had been criticized and asked to write self-reviews for fighting and skipping classes in the past.

Nuannuan was biting the tip of the pen and thinking about how to start writing when Gu An came over.

"Don't worry, sister. I'll help you write once I finish mine."

Upon hearing this, Nuannuan walked over to take a look at the little brother's apology letter, and then fell silent.

"I think I should write it myself. If you write it for me, the teacher will recognize it immediately."

Gu An scratched his head - "Why? Oh, by the way, my handwriting is different from yours, so how about I write it once and you copy it down?"

Nuan Nuan - "No, brother, the idioms you used are very unique. The Chinese teacher will cry when he sees them."

Li Jingshu also came over to take a look, and then almost laughed to death.

"Hahaha...Gu An, after all this time, why is it that your use of idioms is still so difficult to describe? Hahaha..."

Huo Changfeng didn't study in the same school as them before, so he didn't know the power of Gu An's idioms. When he saw them, his eyes were almost blinded by those idioms that were misplaced and didn't make sense.

After a pause, he asked, "Your former Chinese teacher... thank you for your hard work."

Although his academic performance is not that good, at least he doesn't use idioms incorrectly.

Gu An scratched his head, feeling very good about himself and not feeling anything was wrong at all.

Then when I finish writing it, I hand it over to the Dean of Studies.

The Dean of Studies fell silent after seeing this and took a deep breath to calm himself down.

Gu An was quite proud of himself - "Teacher, I didn't look for it on the Internet. I wrote it all by hand."

The dean's fingers trembled and he said in a difficult voice, "Your groundbreaking apology letter cannot be found on the Internet!"

"Yeah."

The dean pointed to the door and said, "Go out. I will give your apology letter to your Chinese teacher."

He can't be the only one who has to deal with the heart attack.

Nuan Nuan asked worriedly, "Teacher, are you okay?"

The dean of studies forced a smile. “Nothing? What could possibly happen to me? Let’s go.”

As he spoke, he drank tea to suppress his surprise.

Nuan Nuan——“…” I don’t think you’re in good condition.
