After dinner, Li Guizhi chatted with Zong Jia for a while before quickly telling him to go back and rest.

The next morning, Li Guizhi drove the two children to the train station to join the rest of the group.

When Chen Zhe saw a tall and handsome boy following Jiang Xiaoli, he immediately became nervous. Could this girl be in a relationship? Then, when he saw Li Guizhi following behind, he breathed a sigh of relief.

Li Guizhi introduced to Chen Zhe, "Teacher Chen, this is my godson, Zong Jiayu. He is accompanying Xiaoli to Shanghai to take the exam. We will cover the expenses ourselves. We just need your permission to let the two children go to the sleeper car when they get on the train."

Chen nodded after listening, "Okay, no problem."

Soon, he seemed to realize something and turned to look at Zong Jiayu, "You were last year's top scorer in the college entrance examination?"

Zong Jia nodded. "Yes, it's me."

This time, Chen's smile seemed much more genuine. "Haha, it really is you! Not bad, not bad. You've gone home for winter break, haven't you?"

They chatted for a few minutes, and then Jiang Xiaoli pointed to the side and said, "Teacher Chen, the teacher over there is calling you!"

Nine students from Qin Province participated in the National Mathematics Winter Camp, led by three teachers.

Forty minutes before the train departs, all students and teachers have arrived and entered the waiting hall.

When Chen was handing out train tickets, he noticed that Jiang Xiaoli already had a sleeper ticket in her hand.

"Teacher Chen, please take this ticket. Leaving a seat empty will give you more space, and you can take turns sleeping for a while."

Hearing her words, Xu Xing glanced at the ticket in her hand and asked, "You bought a sleeper ticket, is that okay?"

Jiang Xiaoli nodded, "I've already spoken to Teacher Chen, it's fine."

The team leader overheard their conversation and pulled Chen aside, saying, "How could you agree to let the students move to sleeper berths? Who will be responsible if something goes wrong?"

After Chen explained, the person in charge's expression softened a bit. "We don't necessarily want the student to suffer in a hard seat. It's mainly for safety reasons. Since she has someone with her, have her and her family write a guarantee and bring it over."

There was no other way; before even getting on the bus, a guarantee had to be written.

After she and Zong Jia finished checking their tickets, they separated from the main group on the platform. Only after they got to the train carriage did she realize, "You bought a soft sleeper ticket?"

Zong Jia nodded. "I've bought all four seats. Close the door later, and you can rest assured."

Jiang Xiaoli gave him a thumbs up, "Brilliant! Absolutely brilliant!"

The train had been moving for about half an hour when there was a knock on their compartment door, and Chen arrived.

She quickly invited Chen to come in and sit down, "Teacher Chen, you're here! How are things over there?"

Chen wiped the sweat from his brow. "Why is the Spring Festival travel rush starting so early? There are just too many people. I walked through more than ten carriages and got all sweaty. Anyway, I'm glad to see you all safe and sound."

Seeing that she was about to leave, Jiang Xiaoli took out several boxes of self-heating hot pot, pork jerky, and boneless chicken feet from their food bags and put them in a bag for him.

"Teacher Chen, we brought a lot of food. Please take it back and share it with them. If you get sleepy tonight, you can take turns coming over to rest. We also bought tickets for the other two private rooms."

Chen was surprised by their generosity. He looked at the snacks in his hand and thought of her food factory, so he didn't say anything more. After all, he, a student, was a real big boss!

He waved his hand and began his sardine-can journey, squeezing back into the hard-seat carriage.

The person in charge was relieved to see him return carrying a bag of food.

Just then, one student finished making a scene, and another girl was uncomfortable being squeezed by people without seats.

She said with a tearful face, "Teacher Duan, why can others take sleeper berths but we can't? You can't be biased just because she got first place!"

Her question immediately attracted the attention of the students around her. Most of them were traveling far from home for the first time and were feeling uncomfortable sitting there. Thinking about the more than 20-hour journey ahead, they all looked expectantly at Teacher Duan, the person in charge.

Teacher Duan sighed, "We only agreed to let Jiang change carriages because she has family with her. Please bear with it, everyone. I'll treat you all to something delicious when we arrive in Shanghai tomorrow!"

Upon hearing that Jiang Xiaoli was accompanied by family, the students, though unhappy, stopped causing trouble.

Chen watched from the side. On his way back, he had been thinking that a teacher could accompany the students so that they could take turns resting in Jiang Xiaoli's sleeper berth for a few hours. But after this incident, he didn't say anything, and just distributed the snacks.

The train had only been traveling for a few hours when Jiang Xiaoli felt so bored she wanted to pick her toes.

She rummaged through her backpack, but there wasn't anything interesting inside.

Zong Jia had been reading a book ever since Teacher Chen left. She kicked the edge of the bed opposite her and asked, "What are you reading?"

Zong Jia moved his hand away to show her the cover; it was an original English book.

The title means "Hypertext and Hyperlinks".

Jiang Xiaoli waved her hand, "You can continue watching."

He closed the book after a few clicks of the page numbers. "Bored?"

She nodded. "Twenty more hours... how are we going to get through that?!"

Zong Jia took another book out of his bag. "Want to read for a while?"

Jiang Xiaoli had just become a little interested when she saw the book's title: "Fundamentals of Internet Technology".

She flopped onto the bed and waved the little white flag, saying, "See? I'm going to sleep."

At first, she couldn't sleep because of the clattering of the train, but after a while, she got used to the swaying rhythm and slept quite soundly!

When she woke up, all the lights in the carriage were off. She sat up and was about to get out of bed when Zong Jiayu across from her also woke up.

The two of them asked in unison, "Are you hungry?"

"Haha." Jiang Xiaoli chuckled. "I was asleep, so why didn't you eat either?"

Zong Jiayu's voice was also cheerful, "I was afraid the smell would be too strong and wake you up."

He pulled a flashlight out of his bag. "Here, pick out some dinner for us."

Using the flashlight, Jiang Xiaoli took out several boxes of food from the food bag.

The two didn't go to the tea room; instead, they made a self-heating hot pot using bottled water.

While waiting for the self-heating hot pot to be ready, Jiang Xiaoli quickly opened a box of pork jerky.

She put one in her own mouth and held it there, then gave Zong Jiayu another one.

The two ate some snacks, and then the self-heating hot pot was ready.

Jiang Xiaoli said with a grin, "Don't you think it tastes really good to eat on a train in the middle of the night?"

Zong Jia looked at her small face in the dim light and echoed, "Mmm, it smells good."

After finishing their meal, Zong Jiayu tidied up and went to throw away the trash. Jiang Xiaoli leaned against the blanket and began to doze off again.

When Zong Jia returned, she was drowsy and about to fall asleep.

He came over and covered her with the blanket, saying, "Be careful not to catch a cold."

Jiang Xiaoli obediently let him cover her with the blanket, and whispered, "I just woke up, but I feel sleepy again after eating. Am I a pig reincarnated?"

Zong Jia chuckled softly, bent down and patted her head, "Cute little pig, go to sleep."
