Lin Chaoxi has been wondering what she would do if she were Lao Lin.

She might bring her daughter to see Pei Zhi, but she would never easily decide to stay and accompany the boy through the most painful time of his life.

She didn't understand why Lao Lin could make the decision so easily, as if staying in Yongchuan for a week and letting her not go to school were very easy things.

Lao Lin took her to a random guesthouse.

Located between Yongchuan University and Ci'en Hospital, Lin Chaoxi suspected that Old Lin had lived in this guesthouse. It was deep in a narrow alley and looked quite old.

The room had a one-meter-high green wall, gray polished floor tiles, a wooden bed, and even enamel teacups and crystal ashtrays from that era. Fortunately, the guesthouse was very clean, so Lao Lin asked for a family room with two rooms and a computer with internet access.

Lin Chaoxi put down her schoolbag on the coffee table and realized that Old Lin had really decided to take her to live in Yongchuan for a few days.

All the plans were indeed messed up, so what should she do with her program?

"Aren't we going back?" Lin Zhaoxi turned around. "Where's your thesis? Don't you have to give a report?"

Lao Lin took out a bunch of keys from his pocket, pointed at the pendant on it and said, "Don't you know there is something called a USB flash drive?"

"Where's my class?"

"Why are your grades so good? Isn't it just because you can skip classes if you want to?"

Old Lin imitated her tone so well that Lin Chaoxi was choked and speechless. She could only say, "But I didn't bring any clothes."

"It doesn't matter. Someone wants it anyway."

Lin Zhaoxi: “…”

Lao Lin defeated her, then leisurely turned on his computer, sat down on a chair, and inserted the USB drive.

She had no choice but to pick up the electric kettle to boil water. She inadvertently saw Lao Lin's back as he sat at his desk, but she could not feel the relief she usually felt after arguing with him.

Lao Lin seemed to be downloading some software, and suddenly turned around and said, "Don't think too much. There are still many details to revise in the paper. I go to Lao Zeng's place to report every day, so it's convenient to live here."

Lao Lin sensed her emotions and began to comfort her.

At this moment, Lao Lin stood up, picked up his coat hanging on the back of the chair, and said, "Let's go~"

"Where are you going?"

"Buying clothes for my little daughter and some medicine," he said.

——

While strolling around the night market with Lao Lin, Lin Chaoxi got a general idea of ​​the nearby geographical situation.

There are three Internet cafes nearby, not far from Sanwei University. One of them looks very high-end, with a 1000m broadband high-speed connection to the Internet.

The remaining two are relatively small, but seem to be open to minors accessing the Internet.

As she walked, she thought about what she should do first, and decided to collect the traffic data of Yongchuan area again.

Sanmi University does have road information and reference books, which are very comprehensive, but a lot of traffic data can only be obtained by someone else.

Then repeat the previous process again...

She tried not to think about the difficulty, but rather how many days and nights she had spent sorting data, setting parameters, and fixing bugs to complete the program.

She and Lao Lin walked in the night market, the lights were dim.

She told herself that Lao Lin had made the best decision for her.

Then she should try again.

After returning to the guesthouse, the first thing she did was to call Chen Zhu.

The phone rang many times before it was picked up. Chen Zhu must have fallen asleep and was woken up by her.

Lin Chaoxi stood in the corridor of the guesthouse and briefly stated his plan.

"You won't be back in Yongchuan this week, so let me pack all the programs for you?" Chen Zhu's voice suddenly became clear, "Am I dreaming?"

"It's just a sudden thought." Lin Chaoxi tried to finish her words at once, otherwise she herself would think this matter was unreasonable. "Also, please tell uncle that the location of my request has changed. I also want the traffic data of Yongchuan City."

"I'm definitely not awake yet." said Chen Zhu.

"No, brother, you are sober." The hand holding the phone quickly froze, and Lin Chaoxi changed his hand and said, "I want to do something with a smaller scope but more accurate prediction, the location is Yongchuan."

There was silence on the other end of the line for a while, and Chen Zhu finally said, "This is not cool at all."

Lin Chaoxi didn't know what he guessed. After a while, she said in a very soft voice, "Please help me."

There was another long silence on the other end of the phone, but Chen Zhu was still a straightforward person: "Think about what documents and procedures you want, and try to write a complete list. I will package it and send it to you."

"Thank you."

The call was disconnected.

Lin Chaoxi was lying on the railing in the corridor of the guesthouse, not wanting to sleep at all.

If possible, she would like to take the money and go to the Internet cafe to stay up all night. But in fact, she has nothing in her hands.

She stood in the deserted corridor, the clouds blocking the moonlight, making her feel cold.

——

Lao Lin had already given her enough pocket money.

The next morning, Lao Lin went to Sanwei University, while Lin Chaoxi went directly to a small Internet cafe and booked two of the best machines, with excellent Internet speed and hardware.

Chen Zhu sorted out all the documents for her overnight and sent them to her in a package.

In the morning, the Internet cafe is filled with the smell of cigarettes and instant noodles after staying up all night, and the air in the closed space is stuffy in winter.

Lin Chaoxi sat in front of the computer in the Internet cafe, took a deep breath, opened the program, and dragged the scroll bar.

She typed every line of code on the page herself. She originally thought that any problem in modifying the program could be overcome no matter how difficult it was.

But when she saw every line of code she had typed, she still felt like she was standing in front of exquisite ruins.

Although the buildings are still there, they are useless and she is about to tear them down with her own hands.

She sat in front of the computer in silence for a while.

The young people who were playing games all night shouted "Fuck it".

Lin Chaoxi rubbed his face and forced himself to cheer up.

She reread the code she had written and began to organize her ideas for revision.

First, she called up the map of Yongchuan area.

Although the actual predicted area of ​​Yongchuan seems to be reduced, it is a megacity. Its road data, traffic volume, and traffic accidents are far from Anning.

In predicting the car accident in Anning City, she set several possible departure locations for Lao Lin, and the whole process was carried out based on this.

In Yongchuan, Lao Lin's starting point has changed. Because of the change of city, she does not have much original data to refer to, so it will be more difficult to predict Lao Lin's path of action.

This is only the smallest difficulty. The bigger difficulty is that she doesn't even have the basic traffic data for Yongchuan.

Then came a call from Chen Zhu's father.

There was no such a lot of preparation as before. Lao Chen only said four words: "I can't do it."

Lin Chaoxi coughed several times due to the smoke from the Internet cafe: "Uncle, you are all in the same system, don't you know anyone? Can you use your connections?"

"Honestly speaking, Yongchuan is too far from home. The relationships in big cities are more complicated than you think. If you want traffic data for Yongchuan, I really can't do that."

"Maybe you have a friend who works in the Yongchuan transportation system? Can you ask your friend about it?"

Lao Chen was probably her greatest hope, so she asked persistently.

"Chao Xi, why are you so persistent? What you want is beyond what you should do at your age."

"Could you please try again and ask for me?" she insisted.

"Why do you suddenly want Yongchuan's things again?" Finally, Chen Zhu's father couldn't help it.

Lin Chaoxi held the phone tightly, thought for a moment, and replied: "If you need an explanation, I can say that it is because I suddenly felt that I could easily complete An Ning's prediction, so now I want to challenge Yongchuan."

She said this and took a deep breath: "But if you want me to tell you the truth, I can only say, 'No reason'."

Like his son, Chen Zhu's father also remained silent for a long time.

"Okay, I'll ask for you again." said Chen Zhu's father.

——

After hanging up the phone, Lin Chaoxi continued to look through her address book.

If this was the 22-year-old Strawberry World, she had quite a few college classmates and friends in Yongchuan, and she could shamelessly ask her acquaintances to go to the transportation department to ask for help.

But now she is only 16 years old and she only knows a few people.

Lin Chaoxi held the phone tightly and called Li Ran.

The same process applies to all adults when making requests.

She was asked to explain her reasons, was told that her idea was too exaggerated, and finally asked what she wanted to do. She could only beg.

Jie Ran was relatively easy to talk to and agreed to ask for her.

When it came to William Chang’s turn, it wasn’t so easy to pass.

She was first covered in the face and scolded, and then asked what she wanted to do.

It had been a long time since she had felt like she had been lectured by a teacher, but she could only bite the bullet and keep saying "thank you".

Finally, before hanging up the phone, he said, "I don't know the person, but I can help you ask."

She looked through the address book on her phone and finally saw a name.

She didn't know why, but she suddenly felt a lot of sadness in her heart, but also felt happy.

She stroked the screen of her phone, pressed the name, and finally put the microphone to her ear.

After a long waiting tone, the call was finally connected.

"Xiao Meng, could you please help me?"
