Coming back is a matter of a moment.
Surrounded by the hospital lobby, a tear rolled down my cheek.
The lights are bright and the noise is overwhelming, majestic and full of vitality.
Lin Chaoxi stood outside the infusion waiting room. People were coming and going. On the waiting screen, the red name number jumped.
"Next one." The doctor called out in the consulting room.
Looking down, she was still holding the letter. On it was the word e=mc^2 written by her, with the tip of the ballpoint pen still touching the end of the number 2.
Is she back?
She seemed to still be in the dim garage, and her vision was temporarily difficult to adjust.
Behind me, the door opened and closed again.
"Student Lin, can you return my pen to me?" A weak voice asked.
Lin Chaoxi turned around and saw the young man Lu Zhihao. He was tall, with a round white face and a somewhat confused expression.
She shuddered and instantly came to her senses. Her first reaction was to fold the envelope and put it in her trouser pocket. Then she took a deep breath and calmed her breathing.
"Pen..." Lu Zhihao said again, "I want to carry it with me, so I can't give it to you."
Lin Zhaoxi quickly handed the pen over: "I'm sorry, I'm sorry."
"What happened?" Lu Zhihao turned around, pushed open the door, and asked before going in.
Being reminded of this, Lin Chaoxi covered his forehead with his hands, and many scenes came to his mind.
This is Strawberry World. She is already a senior. Because of Alzheimer's disease research, she accompanied Lao Lin to meet Lu Zhihao's mentor.
It was from this that she learned that Lao Lin’s current Alzheimer’s disease was caused by a car accident many years ago.
After understanding the purpose of the research, Lao Lin agreed to be a "guinea pig", but asked a person to take an intelligence test.
Lu Zhihao was called out by Lao Lin and handed an envelope to her.
According to Lao Lin, what was written inside was the answer to the question that Pei Zhizeng had unloaded from the blackboard.
At that time, she saw the advertisement of Huajuan and was touched. She grabbed the envelope, snatched Lu Zhihao's pen, ran madly, and wrote "Time Travel Formula" on the envelope at the moment she pushed the door open...
That's what just happened.
"No, it's nothing serious." Lin Chaoxi held onto the door frame and said reluctantly.
It's just a time travel, it shouldn't be a big problem.
"Then I'll go in and wait for uncle to fill in the IQ test. Do you want to join me?"
"You go ahead. I'm here. I'm fine standing here."
——
After taking some time to calm down, Lin Chaoxi found an empty seat outside the waiting room and sat down.
She took out the envelope again. On it was the line she had just written: e=mc^2. The ink from the ballpoint pen was clear and shiny, and it seemed that the ink had not yet dried.
She felt both emotional and helpless.
The program for the Heavy Cheese World had not been completed, and Lao Lin had not been rescued, but she was sent back like this.
I don’t know how Pei Zhi is doing. After she leaves, will Zhong Lin Chaoxi still study hard and continue to work hard?
It feels like there is a lot of unfinished business.
Without giving it much thought, she simply tried writing e=mc^2 again on the envelope.
Looking up, it was still the hospital corridor, and the girl was supporting her mother as they walked into the clinic.
Nothing happened.
Lin Chaoxi was helpless, as the magic door didn't seem to work all the time.
But thinking back, although Zhonglin Chaoxi was a little bit out of shape after she left last time, since the world line is constantly branching towards new branches, she has stayed there long enough, and now the brand new her in that world should continue.
After all——
Lin Chaoxi took a deep breath. After all, when he turned to Pei Zhi's answer, who could not be moved?
Calming down his mind, Lin Chaoxi touched the envelope again and suddenly thought, it doesn’t matter what the answer is, what matters is whether you have done it.
And perhaps she came back this time because she kept thinking about learning newer programming knowledge seven years later, and time and space gave her such an opportunity.
But this is also speculation, there are many things she cannot control.
All she can control is herself in this world.
No matter whether she can go back or not, no matter whether she can arrive at the time before Lao Lin’s car accident before she goes back next time, or even no matter whether it is meaningful for him to save Lao Lin in that world.
Even in this world, she cannot give up and must keep working hard.
"What's wrong? Did Dad's letter give you a lot of insights?"
A leisurely voice sounded from above his head. Lin Chaoxi raised his head and saw Old Lin's smiling face.
She immediately folded the letter and put it back in her pocket.
"I didn't." She stood up and thought about the real time. It wasn't that long. She asked Lao Lin, "Did you finish the IQ test so quickly?"
"Yes, they are all basic logical reasoning questions. How can I show my level if I do them too slowly?"
"How many points then?"
"The score is not important." Lao Lin said, "It's all full marks anyway."
Lin Zhaoxi: “…”
"Oh, I'm really hungry. The vegetable dumplings in this hospital cafeteria are delicious. Let's treat Dad to a serving to show our filial piety." Lao Lin handed the medical bag in his hand to her and went ahead to find the cafeteria.
"Dad." Lin Zhaoxi called him.
"ah?"
"We're going in the wrong direction." Lin Chaoxi pointed to the other side.
——
When they got home, Lao Lin was holding two steamed buns in his hand, saying that he would eat them the next morning. He put the buns in the refrigerator, and Lin Chaoxi took a bottle of ice water and went into his room.
If time travel is considered a long journey, she is still a little tired from the journey.
She sat down at the desk. Her postgraduate entrance examination schedule was posted on the wall. The question that Pei Zhi had written on the blackboard at that time was pressed under a few books, with only a corner of it sticking out.
In the trouser pocket were the answers to the questions that Lao Lin had put in an envelope. The pocket was already bulging with answers. Lin Chaoxi took the things out and put them aside.
She sat for a while, drank some ice water, and sorted out her thoughts.
She has to take the postgraduate entrance exam, learn machine learning, and continue writing programs. The good thing is that now she has plenty of courses to take by opening a web page.
She then divided the tasks she needed to do into two major parts: the first was to calculate the procedure for where Lao Lin's car would land in the accident, and the second was the math exam.
She made a table with the general progress of Cheese World on the left, and put the next part to study on the right. She also took out the study table she made at that time to compare it to see how to arrange her study time.
Then she suddenly discovered that her experience in the cheese world had made her math level much better than it was a year ago, oh no, about an hour ago.
If she had been running aimlessly on the road before, now she could see the door in the distance, and she would have to redo all her plans for the postgraduate entrance examination.
In order to redo the plan, she must first confirm where her level is. Lin Chaoxi spun the pen and suddenly wanted to know this.
She thought about it, turned on the computer, selected a unified examination paper, downloaded it and printed it out.
The test paper has a full score of 150 points and lasts for 3 hours, so she also follows this time.
If you work hard on the questions, you will know your level and where your weaknesses are. Obviously, she is best at probability theory, followed by linear algebra, and her advanced mathematics is not solid enough.
Three hours later, Lin Chaoxi stretched his back and began to check the answers.
Because she encountered a lot of content that she didn't understand and was unclear about when doing the questions, she started studying while checking the answers.
Before she knew it, when she looked up again, it was dark.
Lin Chaoxi rubbed her eyes. She didn't expect that she had been sitting for so long. She stood up and prepared to eat something.
The test paper was still on the table. She took two steps and looked back at the paper. She answered the questions with pencil and marked them with red pen. The whole paper was filled with dense writing.
She couldn't help but start worrying about another thing: how to explain to Lao Lin that her math skills had improved by leaps and bounds?
The sound of Lao Lin cooking came from outside the house, with the range hood turned on very loudly.
Lin Chaoxi rubbed his temples with a headache, returned to the desk, folded the test paper and hid it.
It’s better not to let Comrade Lao Lin see it, after all, Lao Lin is a smart man among smart men.
Lin Chaoxi walked to the kitchen. There was crucian carp and tofu soup on the table. Old Lin was still stir-frying vegetables. He grabbed a handful of fresh walnuts and threw them in, then continued stir-frying.
"Are you up?" Old Lin asked her directly without replying.
"No..." Lin Chaoxi, who had just finished the test paper, picked up the cup to pour water.
After going around in circles, she suddenly stopped and said, "Dad, you want to ask me if I have studied hard, but you don't have to be so roundabout!"
"What does it have to do with me whether you have studied well or not?" Lao Lin shouted at the top of his voice, trying to drown out the sound of the range hood.
"Then why do you cook crucian carp and tofu soup and put walnuts in stir-fried vegetables for my brain?" Lin Chaoxi also shouted.
"Because your father has Alzheimer's disease, I will train myself!"
Lin Zhaoxi laughed, picked up a piece of fish with chopsticks, and was burned: "Ouch."
Lao Lin came over with the dishes, set the table and sat down.
Lin Chaoxi began to concentrate on eating the fish. Old Lin ate a few mouthfuls of rice in silence, and finally put down his chopsticks: "You really didn't open the letter?"
"Why are you still fussing over this? I really didn't take it down."
"Your father is doing so much for you, why don't you see it?"
"Because I am determined!"
In fact, I was so focused on the test that I forgot about Pei Zhi's question...
"But the submission deadline is 12 o'clock tonight."
Lin Chaoxi's chopsticks fell down.
"you do not know?"
"I have no idea."
“It’s clearly stated in the fine print.”
"I didn't look carefully..."
Lao Lin sighed: "You really don't care about Pei Zhi anymore. You can't fall in love with someone else. You can't have Lu Zhihao!"
"What's going on here? Your reasoning is very logical." Lin Chaoxi quickly took two mouthfuls of rice and prepared to go back to solve the problem.
"You don't even care about the questions now. You don't even read the competition rules. Today in the hospital, I was doing some IQ test and Lu Zhihao came to collect the papers. I saw that he looked very confused. Did you secretly confess your feelings to him?"
Lin Zhaoxi thought of the pen and looked at Comrade Lao Lin's gossipy expression under the lamp. He couldn't help but smile: "Guess..."
After she finished speaking, she put down her chopsticks, stood up, and decided to do the questions, ignoring Comrade Lao Lin's protest.
Lin Chaoxi turned on the desk light, turned off the computer, and took out the questions that were pressed under the book.
The line of small words Pei Zhi wrote on probability theory appeared in her mind again.
How could I not care about him...
I really, really like him.
