The students were all on holiday, and Bai Zhou originally planned to go home, but he called his home during the Mid-Autumn Festival, but his parents quietly followed the "middle-aged and elderly tour group" to go abroad. It is said that it is a January trip to Singapore, Malaysia and Thailand.

If it weren't for Bai's father being the leader of the "middle-aged and elderly tourism group", Bai Zhou would definitely be worried about taking a plane and going there now.

Today, Bai Zhou was checking the Internet at home, "What teaching materials are needed to get started with advanced mathematics?" The doorbell rang.

Bai Zhou opened the door and took a look.

"Teacher Lin? You are..."

Lin Xiao was standing outside the door with a large bag and a huge suitcase on the ground.

Lin Xiao had fine beads of sweat on his forehead, panting, and spoke.

"Teacher Bai, I plan to move here in advance. You won't be dissatisfied!"

"Where is where, it's too late to welcome, come in!"

Bai Zhou took the bag from Lin Xiao with one hand, picked up the huge suitcase on the ground with the other hand, and put it into the room.

"Wow! Teacher Bai, you are so strong!"

"Ding! Get 1 recognition point!"

"Ding! Get 1 recognition point!"

"Ding! Get 1 recognition point!"

...

"Hmm? What's wrong?" Bai Zhou looked back at Lin Xiao who was fussing.

"Teacher Bai, do you know? Just this box and that express driver, he transported it three times before lifting it up a little. Are you so relaxed?"

"Uh...it's okay!" Bai Zhou didn't know how to explain, so he just casually slapped him.

"But Teacher Lin, what is the stuff in your box? It's so heavy?"

Lin Xiao's face turned red and he fooled him a little awkwardly.

"Oh, aren't you moving? You'll live here in the future. Of course, you'll have to have more things."

"If you move, you won't really move your house here, right?"

Bai Zhou pretended to be exaggerated to tease Lin Xiao.

Lin Xiao threw the bag on his back on the sofa and said angrily.

"Teacher Bai, girls naturally have more belongings~"

Then immediately change the topic.

"Teacher Bai, don't forget that you want to pay me a meal of vegetable porridge. Go and cook! I'm hungry!"

Bai Zhou smiled helplessly.

"Since you have moved here, how can you eat vegetable porridge so hard!"

After saying that, Bai Zhou saw that it was almost noon and turned around and entered the kitchen.

When Bai Zhou's apron was not put on, Lin Xiao's little head came in and said embarrassedly.

"That... Teacher Bai, can you help me move the gift to my room?"

Bai Zhou rolled his eyes, but he still left the kitchen.

In Lin Xiao's stunning gaze, Bai Zhou easily picked up the one with one hand, feeling that he could put both Lin Xiao into the suitcases.

"This will be your room from now on. I will sleep next door. Don't go to the wrong room at night!"

Lin Xiao didn't care about Bai Zhou's jokes, and lay on the solemn bed in the room, breathing a sigh of relief.

"Ah! I'm so tired of moving my luggage today!"

Bai Zhou shook his head helplessly when he looked at Lin Xiao, who was not paying attention to his image at all, and said to himself.

"Teacher Lin is not like this in front of the students. Why is the little girl's nature exposed at this time!"

Bai Zhou said, pulling his suitcase to the ground.

"Take a gift and clean up yourself, I'll go out first!"

As he said that, Bai Zhou was about to move away, he just arrived at the suitcase. As soon as the suitcase left Bai Zhou's hand, the wheels were unstable and tilted. He just slapped the ground with helpless slap.

With a loud "bang!", Bai Zhou felt that the house seemed to be shaken.

Just as I was about to complain, I heard a "puff!" sound, and the suitcase shattered directly, and the things inside seemed to explode and spread out.

Bai Zhou was so close to him that he saw a triangular light pink object magnifying infinitely in front of him. The next moment, the darkness in front of him covered Bai Zhou's eyes.

"Ah!" Lin Xiao's scream made Bai Zhou feel like he was deaf.

With a "swish!", Bai Zhou saw the light again, Lin Xiao's face turned red, and his hands were behind him and he didn't know what was hidden.

Bai Zhou wiped his nose.

"Uh...I'm going to cook!"

Then he turned around and left Lin Xiao's room without looking back.

...

In the kitchen, Bai Zhou was busy preparing a sumptuous lunch to welcome Lin Xiao.

Lin Xiao walked into the kitchen with a bottle of fire extinguisher in his arms. While looking at Bai Zhou, a hint of shyness flashed in his eyes.

"Teacher Lin, you are..."

"Oh! Teacher Bai!" Lin Xiaoyang raised the fire extinguisher in his hand.

"I bought five bottles of fire extinguishers on the way back. Last time I came to see Teacher Bai's house as big as a house, and there was no fire extinguisher. I'm not preventing any problems!"

After saying that, Lin Xiao found a corner in the kitchen, put down the fire extinguisher, quickly left the kitchen, and said as he walked.

"Teacher Bai, your room is not locked, I'll put a bottle for you too!"

"No!" Bai Zhou responded helplessly, looking at the fire extinguisher on the ground and thought to himself.

"Have five bottles of fire extinguishers installed in the suitcase? No wonder the express driver can't carry it up!"

Lin Xiao held a bottle of fire extinguisher and pushed open Bai Zhou's door. The scene in front of her made her stunned involuntarily.

"Is this a man's room?"

In her heart, the boy's room was either messy and covered with dirty clothes, or was filled with all kinds of strange smells.

It's not her fault for having such prejudice.

The room she talked about the most about men when she grew up is the boys' dormitory of their class!

Looking at the simple and clean room, Lin Xiao involuntarily took a deep breath of the air here.

Except for the faint mint-flavored washing powder, there is no other smell.

Bai Zhou, who was cooking, suddenly heard a system prompt sound in his mind.

"Ding! Get 1 recognition point!"

"Ding! Get 1 recognition point!"

"Ding! Get 1 recognition point!"

...

Bai Zhou said while holding the spoon.

"What did this girl see again? Is there any approval points to put a fire extinguisher?"

Lin Xiao put down the fire extinguisher next to Baizhou's bedside table, raised his body and saw a thick stack of A4 paper on the bedside table.

Driven by curiosity, Lin Xiao picked up a chapter.

"This is...this is the test question for high mathematics?!"

She was a little surprised to find that on this thick stack of A4s, all the printed questions were high-mathematical questions.

"There is only one question on each A4 paper, and each question is solved. The full A4 paper is full of problem-solving methods? Different problem-solving methods?!"

Lin Xiao has read the "dictionary" written by Bai Zhou himself, so he naturally knows Bai Zhou's notes.

"Teacher Bai..."

Lin Xiao said Bai Zhou's name dazedly, and she was completely demented now.

"Teacher Bai studies Old English and can speak Little Sun Language. There is no problem with this. After all, he is a counselor in the Department of Foreign Languages ​​and Literature, but senior mathematics! Senior mathematics, a subject that even students majoring in mathematics have a headache. Does Teacher Bai have in-depth research on it?"

Lin Xiao looked at the same problem-solving ideas one by one, and suddenly slapped his forehead.

"Answer, answer! There must be a reference answer!"

Then she began to frantically search for the four big words "reference answer" in this stack of A4 paper, and soon she was disappointed.

"No? How could it be?"
Chapter completed!
