Time goes back to before she came to the cheese world this time.

That night, she played badminton with Pei Zhi and his friends, as well as the future Zhang Liang. After returning home, she flipped through the photo album of the pink-faced little white flower.

She was sure that the letter in the same album was from Professor Paul Gee.

That was Lao Lin's mentor who was destined to be with him but not to be with him. Because he did not report to chu, the professor wrote to him several months later to inquire about the reason.

Now is this moment in the cheese world.

The same photo album, the same number of pages, but the letters inside have undergone some subtle changes.

Although both the inquiry letter and the admission letter indicated that Lao Lin ultimately failed to go to chu, they were different after all.

But why is it different? Lin Chaoxi began to think.

On the stone table, a hand quietly reached out and touched the acceptance letter.

Lin Chaoxi was quick to grab the letter.

Lao Lin sat upright and did not let go.

At this time, in another plot segment, Lao Lin 7 years ago.

In this plot, she is no longer a burden to Lao Lin. Lao Lin received the acceptance letter, but still could not continue his mathematics studies.

So what's the problem?

This time, Lin Chaoxi asked directly: "Why don't you go to school?"

"Because I did something wrong." Lao Lin answered more straightforwardly.

Lin Chaoxi took a deep breath. He never thought the answer would be so simple.

She asked tentatively: "Emotional problems, starting with chaos and ending with abandonment?"

"I'm a little embarrassed to say this."

When Lao Lin said this, he avoided her gaze in shame. Lin Chaoxi had never seen Comrade Lao Lin like this before, so she widened her eyes and blinked twice.

"I don't understand." Lin Zhaoxi said, "Why don't you have a wife? Why don't you want me? Why don't you concentrate on your studies when you are all alone?"

Lin Chaoxi raised the questions in his heart in one breath.

The courtyard suddenly became quiet again.

She looked at Lao Lin, and Lao Lin looked at her.

After a while, Lao Lin stood up and walked to the coal stove at the foot of the wall.

He opened the lid of the pot, scooped up the thick porridge with a long spoon, took out a bowl and placed it in front of her.

Lin Chaoxi took the porcelain spoon handed to him by Lao Lin and calmed down.

Her question is ridiculous.

How could Lao Lin abandon his wife and daughter, not to mention give up his studies? So she actually already knew the answers to these questions.

——I’m not, I don’t, it’s those trivial things that made my life go astray.

"I'm sorry." Lin Zhaoxi said, "I think I want to know the answer too much, but these are actually your business."

She finished her words and began to drink her porridge without saying anything. The porridge was a little hot, but she drank it quickly in order to pretend that she was eating seriously.

"Look, this is actually the case. I don't know if you can accept it." Lao Lin's gentle voice came from the front of her.

He said, "Because your mother didn't want me, I lost you, so I thought that studying was not a big deal, so I gave up on it."

——

At night, the rain got heavier again.

Lin Zhaoxi sat at the desk with a piece of white paper in front of her. It was late, but she didn't fall asleep.

In the dark night, the light in front of the desk was dim, and Lao Lin's words echoed in her ears over and over again.

Lao Lin is always like this.

Whenever he talked about a key issue, he always used the simplest and calmest description, which was logical, frank and sincere, as if these things were really no big deal.

But then she thought, she knew Lao Lin very well.

She knew very well how much Lao Lin loved mathematics. How could it be no big deal that he didn't even want to continue his studies because of the loss of his daughter?

She came from the real world and knew that there were many things going on. She knew that Lao Lin was punished for academic misconduct and that his unfinished thesis almost made him regret for the rest of his life.

But in Lao Lin's narration, there was no mention of these.

Lao Lin didn't mean to hide it, but to him, these were just trivial matters not worth mentioning.

Lin Chaoxi rubbed his face.

In Lao Lin's heart, she is more important than she thinks.

The raindrops hit the tiles, making a rustling sound, and the glass was covered with a layer of mist.

Lin Chaoxi couldn't help but think of the first time she came to the cheese world. She couldn't find her father, so she stood on tiptoe and looked out the window.

Later, she met Lao Lin, who became a manager in the park. At that time, she thought of many reasons, and she also thought that Lao Lin started to exile himself because he lost her, but she didn't dare to think deeper.

This seems to be the case often between parents and children.

On the one hand, they always believe that they are very important to each other, but on the other hand, they are already panicking because they are uncertain about their importance.

Perhaps it was because of this feeling that she always wanted to figure out the relationship between her and Lao Lin's life.

She also wanted to know what ultimately caused the two world plot lines to deviate?

Lin Chaoxi thought for a long time and finally picked up the pencil.

Although she could not give a complete picture of many things due to lack of details, she was still able to organize and speculate.

She drew two long lines on the paper and marked arrows on the right to represent the timelines of two different worlds.

The time can only be roughly estimated, so she roughly divided the time cutoff point online, and used an avatar of a little girl with a ram-horn braid and a number after her head to roughly indicate her age, as a time marker.

y is the abbreviation for age.

*Items are guessed

【Realistic Strawberry World】

Daughter-0.ny——Found guilty of academic misconduct

Daughter 0 y——Wife doesn’t want him (according to Strawberry World information)*

Daughter 0.ny - left school to raise a daughter

Daughter 1 y——Professor PG asked Lao Lin why he didn't go to school

My daughter, 22 years old, had her paper on graph isomorphism plagiarized by her tutor

【Parallel Cheese World】

Daughter-0.ny——was found to have committed academic misconduct (according to Strawberry World information)*

Daughter - 0.1my——Received the admission letter from Chu (postmark date was before my daughter was born)

Daughter 0y——Wife doesn't want him, lost daughter

Daughter 0.ny - left school and became a park manager

Daughter 12 years old - Reacknowledged

She stared at the paper for a long time and found that the problem was not as complicated as she had thought.

Based on the information she currently has, the elements of the incident are roughly: academic plagiarism, her birth, her mother, the letter in the album, and her fate.

At present, there are two changes.

1. Her fate

2. Letter in the Album

And all the problems occurred at the time node of "before and after her birth".

Let’s first look at the most important event, “Mom”——

Because she doesn't have a mother in the real Strawberry World, she is basically certain that her mother in the real world doesn't want Lao Lin either.

So the "mother" problem should not have led to a change in her fate.

Let’s look at plagiarism again——

In the parallel cheese world, Lao Lin also has not completed the paper on graph isomorphism. She only needs to go to Yongchuan University to check the yearbook to get the answer.

As it stands now, this incident most likely has nothing to do with the change in her fate.

so……

Lin Chaoxi looked at the words he had written, "Letter in the Album," and became confused again.

Although she didn't understand why, it seemed that this incident was related to her fate?

If you are confused for a long time, you will feel sleepy.

Lin Chaoxi lay on the table, dazed.

After a while, I felt that her reasoning was not rigorous. Although my mother didn't want Lao Lin, it might be that her change in the way she didn't want her led to a change in her fate.

On the contrary, the difference in the letter is likely to be an event related to academic misconduct but independent of her fate.

After all, a lot of key information is missing, and people become even more confused when they think too much about the problem.

Lin Chaoxi lay on the table and marked another day on the calendar in his mind.

Before she knew it, she had been here for more than eighty days, and there were still fifteen days left before Lao Lin and she finally left this world after the car accident.

——

the next day.

Lin Chaoxi was very angry when he woke up.

It wasn't because her arms were numb from lying on the table all night, nor was it because her face was black from pencil marks.

It was because according to the routine in the novel, on an important night, people should always dream about something. But she slept soundly, not only did she not dream at all, but she also drooled over half a sheet of paper.

"It's eight o'clock!" Lao Lin shouted in the yard.

"I'm awake!" Lin Chaoxi became more awake.

Today is the weekend, and Lao Lin asked her to get up early, which was something she had asked Lao Lin to do two days ago.

She had originally agreed with Pei Zhi and Chen Zhu that after the math league, they would take some time to test the prediction program. But now, Pei Zhi was obviously unable to carry out the plan.

Lin Chaoxi pursed his lips, crumpled the paper into a ball, stuffed it into his pocket, rubbed his face twice, and walked out of the room.

Lao Lin was digging the soil by the courtyard wall, digging out the tulip bulbs that he had buried yesterday. The soft morning light of late autumn and early winter fell on his back.

"Are you still mistaken?" Lin Chaoxi asked.

"I asked Lao Li when I was buying groceries," Lao Lin said honestly, "but it's nothing serious."

On the stone table was the breakfast that Lao Lin had bought.

Lin Chaoxi knew very well that due to the heavy research workload, Old Lin had not bought her breakfast for a long time.

Now he was turning the soil and buying breakfast, all because of the conversation last night. Lao Lin didn't know what her attitude would be, so he was nervous and tried to find something to talk to her about.

As the soy milk was steaming, Lao Lin turned around and smiled as if everything was under control.

Lin Chaoxi's originally confused emotions suddenly calmed down.

She clutched the paper in her pocket.

In fact, the world line had changed as early as the moment she was born, but she is still her, and Lao Lin is still the Lao Lin of seven years ago.

No matter whether all attempts really make sense in the end, she will continue to try.
