Wang Tianyi followed Tang Yuan and Mu Tong, running very fast. He had already reached the highest speed he could reach, but the two people in front seemed to have no limit. If they were in the Olympics, they would break the record every minute.

"We flew separately before the disaster. It felt like we were going to be late. One was running faster than the other." Wang Tianyi saw them getting farther and farther away from him and shouted: "You two, wait for me!"

He came to the lobby on the first floor of the school. There were passages on both sides, and there was a staircase directly in front of him that led to the second floor.

"They should have gone upstairs just now." Wang Tianyi went upstairs directly, but he didn't know where he was going to go after that.

He slowed down and after going upstairs, he looked at the corridor on the second floor and then at the stairs leading to the third floor, not sure which direction to go.

"These two guys are not brothers enough." Wang Tianyi thought through gritted teeth.

"Class has already started, why are you still here?" Suddenly, a loud voice sounded from behind.

The "person" who spoke was a middle-aged man wearing casual sportswear. He had a friendly face, a flat head, round-rimmed glasses, a slightly crooked nose, and a stack of students' homework books in his hand.

However, his skin was very pale and covered with cracks, like the marks of a broken porcelain doll being put back together again.

This person is the same kind as the children Wang Tianyi met while playing the handkerchief game before, but those children were more humane and seemed to retain their own consciousness.

"If you are wandering outside during class time, you will inevitably be scolded by the principal if you are caught." The middle-aged teacher said. "Your classroom is in Class 1, Grade 5. Go quickly. The subject is mathematics, and the textbook should be on the podium."

Wang Tianyi was a little confused after hearing this. He felt that this uncle was not a bad person and should sincerely help him.

Seeing Wang Tianyi standing still, the middle-aged teacher raised his foot and kicked Wang Tianyi's butt; "Go quickly, the students are waiting."

"Thank you, big brother." Wang Tianyi nodded, raised his legs and ran to the corridor next to him.

"Wait a minute, the teacher is on the third floor!"

"Oh." Wang Tianyi changed direction, raised his legs and ran upstairs.

"Hey, today's young teachers are all stupid." The middle-aged teacher lowered his head and muttered, with complicated eyes. "Time is running out..."

Wang Tianyi found the classroom of Class 5, Class 1 and walked in.

The entire classroom was filled with students, all of whom had dull eyes and pale and cracked skin. When Wang Tianyi walked in, these walking zombies all raised their heads.

He glanced at these people and found Mu Tong sitting in the last row near the door, but Tang Yuan was nowhere to be seen.

"Stand up!" the short-haired girl sitting on the far right side of the first row suddenly shouted.

All the students stood up quickly and bowed.

Their movements were stiff, as if they were soulless puppets, and their whole bodies exuded the aura of death. Wang Tianyi suddenly felt that he was incompetent as a dead person, and these students were the real dead people.

His emotionless eyes were fixed on Wang Tianyi uniformly. Wherever he moved, his eyes moved, causing him to suddenly not dare to move casually.

Time seemed to have been paused. The students stood motionless, and Wang Tianyi did not dare to move casually. The situation was very embarrassing for a time.

The students seemed to be waiting for something.

This gave Wang Tianyi a hint, and he cleared his throat: "Hello, classmates, please sit down!"

Time started to flow again and they quickly sat down.

Just like the handkerchief game, the "dead man" here should not attack him casually, or he can only attack after certain conditions are met. Therefore, as long as you find the rules, you should be able to get through this class safely.

Wang Tianyi lowered his head and opened the mathematics book on the podium.

"The principal wants to build a 7-meter-long Huangquan Road. Originally, it was built at 1 meter per hour. After 0 hours of construction, it was accelerated to build meters per hour. How many hours will it take to complete the road?"

What? Keep turning the page.

"The principal used 8 mixers to mix the students. In the first hour, he mixed 0 students. Later, he added one mixer and mixed it at the same speed for another 4 hours. How many students did the principal mix in total?"

Are you sure this is a question for fifth grade students?

"The principal's office has a bookshelf, and the books in the first cabinet account for 58% of all books. If you remove the books from the first cabinet and put them in the second cabinet, then the books in the two bookcases each account for 1% of the books.

/,Ask the principal how many books are there?"

Although the story background of the word problems is a bit strange, if you look closely, you will see that these are actually fifth-grade elementary school mathematics problems.

Wang Tianyi flipped through it again and found that there were only three application examples in the whole book. He felt that these questions seemed to contain some information, but after reading for a long time, he didn't know what the question meant.

"Teacher! This class is a review class!" Mu Tong in the back row suddenly said.

Wang Tianyi raised his head and realized that the entire class had stood up again at some point, staring at him eerily. Moreover, their positions had also changed, moving a short distance towards the podium.

It seems that he has been reading for too long, and the students are impatient to wait. If they wait any longer, these students will probably gather in front of the podium.

Wang Tianyi didn't want to imagine what would happen when the students came to the podium. In short, nothing good would happen.

He has never been a teacher, but Mu Tong just reminded that this class is a review class, so is it relatively easy to handle?

"This is a review class, let's do some questions." Wang Tianyi said.

The students in the classroom stepped back slightly, but were obviously not completely satisfied with the answer.

Wang Tianyi picked up the chalk in his right hand and the book in his left hand, and began to copy the three application problems he had just seen on the blackboard. In addition, there were about 40 more arithmetic problems.

"These questions are considered a short test. If you have finished them all, give them to me for a look. If you are correct, you can go out to play in advance. If you make a mistake, you will be punished with ten questions."

The students all returned to their seats.

I am really a genius. Now that I have finished these questions, the class is almost over.

Moreover, they can also be asked to help calculate the three application questions. After getting the answers, they can be directly analyzed by Tang Yuan. It is perfect.

Wang Tianyi was really lazy. He sat on a chair, put his feet on the desk, and touched the headphones hanging around his neck.

Eh? Where are my headphones?

Did it fall off? Wang Tianyi was a little panicked. Those were the headphones that had been with him for many years. There were strong winds and waves.

At this time, a student in the first row stood up, holding a notebook in both hands, and brought it to Wang Tianyi.

"Done it so quickly?" Wang Tianyi still underestimated the ability of the top student.

The little boy looked at Wang Tianyi, his eyes were two black holes, giving people a feeling of resentment, as if he was saying, "Quickly mark the papers, will you let me go out to play?"

Then another girl, the child who just shouted to stand up, also came over.

"Look at it together." It was impossible for Wang Tianyi to calculate every question by himself. He compared the two people's answers and calculated the differences by himself.

The answers to the three application questions are: 1 hour, 97.5 people, 400 books.

As for other arithmetic problems, the two people's answers were exactly the same.
Chapter completed!
