We ordinary people also need to fall in love.

"Let me go over the steps again. The first step is to identify the known time zone and divide it into eastern and western time zones. The second step is to calculate the time zone difference, following the principle of adding for eastern time zones and subtracting for western time zones. Finally, add the travel time."

I just feel like walking out of the classroom so blatantly is too arrogant...

Li Mubai looked up at the clock on the blackboard. It was almost eight o'clock, and the first evening self-study session didn't end until 8:10.

Geography teacher Wang drew a diagram on the blackboard, tapped the route across the Pacific Ocean with chalk, and turned around to take a sip of water.

Taking advantage of the break, Li Mubai quickly picked up his schoolbag, stood up, and walked to the side of the podium.

"Teacher, I need to work at the library from eight to ten o'clock. This is my leave request."

Teacher Wang put down her water glass, glanced at the piece of paper, and without asking any questions, casually accepted it.

"Go."

Li Mubai breathed a slight sigh of relief. He turned around and, under the watchful eyes of more than a dozen people, walked out of the classroom step by step.

This was the first time I had openly skipped class, skipping two evening self-study sessions in a row, and I felt a little complicated about it.

My schoolbag is filled with homework and last week's test papers. I don't know how much of those two hours will actually be spent studying.

Li Mubai walked downstairs, where Xie Shu was already waiting for him under the familiar tree.

"Thank you, Shu." He quickened his pace and walked up.

"Okay." Xie Shu nodded. "Did you bring your homework and last week's test papers?"

"I brought it."

Xie Shu didn't say anything more, turned around and walked towards the library. Li Mubai followed beside her. The campus was quiet at night, and the streetlights cast long shadows of the two of them.

"Let's finish today's homework first," Xie Shu said as they walked, "and then take a look at last week's test paper."

"Aren't we going to do anything?" Li Mubai asked.

"What are you doing?"

"It's the routine maintenance work of the library."

"No, we shouldn't do it. We're in our final year of high school; we should focus on studying."

Li Mubai couldn't help but twitch the corner of his mouth. Xie Shu was probably the most relaxed student in the entire senior year. While everyone else was nervously reviewing and worrying about their mediocre grades, she was using her time to tutor him.

He glanced at Xie Shu's hand hanging by his side, swaying gently back and forth. He hesitated for a moment, but ultimately did not take it.

The library was located next to the first-year high school building, so they arrived at their destination in no time.

At this moment, the senior students are having evening self-study, the freshmen are having military training on the playground, and the sophomores have not returned to school. The hall is unusually quiet and empty.

If you shout, will you hear your own echo?

Li Mubai observed the newly built library, which seemed to have only three floors. The first floor resembled a huge study room, with bookshelves arranged on both sides.

"Should we sit here?" Li Mubai pointed to the tables and chairs next to the main entrance.

"No, we're on the third floor." Xie Shu shook his head.

The layout of the third floor is completely different from that of the first floor. There are offices on both sides of the corridor, with uniform nameplates on the doors and several lights on.

Xie Shu walked to the door of one of the rooms, took out a key from his pocket, inserted it into the lock, and gently turned it.

Li Mubai glanced at the signboard—Library Office (1).

"There are two keys, this one is for you." Xie Shu handed over the other key.

Li Mubai took the key; it was icy cold and had an unreal weight in his hand.

He followed Xie Shu inside, his gaze carefully taking in the room.

The window faces the Confucius Academy not far away. The Confucius Academy is brightly lit at night, and the outline of the eaves is outlined by colored lights.

Two desks were placed by the window, facing each other. The desks were clean and empty. A brand-new floor-standing air conditioner stood in the corner.

I never expected that he would be sitting in an air-conditioned office at such a young age.

Bang.

Xie Shu gently closed the door.

"Actually, we can come here to study and do our homework at other times," she said.

"Mm." Li Mubai nodded.

Xie Shu opened his mouth as if he had something to say, but in the end he held it back.

"Which side would you like to sit on?" Xie Shu asked, looking at him.

"It will be all right."

She sat in the seat on the right, and Li Mubai naturally sat in the seat on the left.

"Hurry up and do your homework, I'll supervise you." Xie Shu looked at him.

"Aren't you going to do your homework?"

"I'm done."

"So fast?!" Li Mubai asked in surprise. Although Xie Shu had excellent grades, there was a lot of homework in the senior year of high school.

"Yes, because we had less written homework today; most of it was memorizing and checking our mistakes."

"Class 3 is still the best. I want to go back to Class 3 too," Li Mubai joked.

"Do you want to come back?" Xie Shu asked.

"No, no, I'm going to do my homework." Li Mubai waved his hand, not wanting Xie Shu to bother Xu Ting or Xie Zhiqiang again.

"Give me the test paper from last week, and I'll look at it while you're doing your homework."

"it is good."

Li Mubai turned around and took out the test paper from his schoolbag. The first uncorrected Chinese test paper made him pause slightly before handing it to Xie Shu.

"Go do your homework."

Li Mubai lowered his head, picked up his pen, and began to write.

beep.

Xie Shu turned on the air conditioner, and a slight coolness rose in the office. The doors and windows were tightly closed, and no outside sounds could get in. Li Mubai could only hear the scratching of a pen on paper and the slight hum of the air conditioner.

His attention gradually focused on the homework on the table...

"I'm done writing." Li Mubai put down his pen and stretched his stiff wrists.

"Okay." Xie Shu put down his test paper, glanced at it, and said, "There are about fifty minutes left. Let's start with the math test paper."

Li Mubai thought for a moment, then lifted a chair and sat down next to Xie Shu, whose lips curled up slightly.

"Has Teacher Chen already gone over the math test? Are there any parts you don't understand?" Xie Shu asked.

"Yes, the last fill-in-the-blank question and the second-to-last essay question."

The office chair was too big; even if the two chairs were put together, there were still 20 to 30 centimeters between him and Xie Shu.

"Now let's look at question sixteen..."

Xie Shu's voice was very soft, and Li Mubai recalled how she hummed softly when they were in Hanshan.

"Xiao Bai, focus." Xie Shu gently tapped the arm resting on the table. "You're going to surpass the number one boy."

"Surpassing number one is too difficult," Li Mubai said with a sigh.

"Therefore, a disciple is not necessarily inferior to his teacher, nor is a teacher necessarily more virtuous than his disciple." Xie Shu shook his head lightly, as if a primary school student were reciting a text, his tone light and cheerful.

The air was silent for a second, then the two of them chuckled.

"I'll just try my best to get second place."

"You still need to work hard and get over 125 on your next math test," Xie Shu encouraged him. "Go for it! I believe in you, and you have to believe in yourself too."

"it is good."

If they get second place, there might be much less resistance between them!

With this in mind, Li Mubai listened attentively to Xie Shu's explanation of the problem.
