The solution of the functions is the point where they intersect.
December 21st, Lao Lin's car accident day.
In the morning, Lin Zhaoxi bought breakfast and stood at the reception alley on time. The fresh-keeping bag contained freshly made rice balls, which were still steaming when they were taken out because they had been covered in clothes.
Lao Lin walked slowly from the end of the alley, as if this was just an ordinary day, and he was just casual. The weather is still cold, but the weather has been fine for several days, and most of the snow has melted away, leaving only the blue sky and the busy streets under the blue sky.
Lao Lin's eyes were bright, as if he had a good dream last night. Lin Zhaoxi stuffed the rice ball into his jacket pocket, and when she took it back, there was an extra roasted sweet potato in her hand.
The skin is slightly charred and has a soft interior when torn. Lao Lin whispered to her that the sweet potato was extremely sweet, and walked to the bus station with her.
About an hour ago, she left the Mercy Nursing Home.
The ward was full of draft paper and books. When she left, the lady on the ward fell asleep again, and Pei Zhi was taking a book away from her mother.
In my memory, it was "Database Modeling Technology". Pei Zhi's mother barely turned a page, but Pei Zhi had already read it all.
The ventilators are still working as hard as they can. In the morning light, Pei Zhi waved goodbye to her.
She didn't tell Pei Zhi why she did all this. For Pei Zhi, he just helped her complete some interesting work while accompanying her through the last few days of her life.
The specific content of the work is not important, what is important is that it all happened in that ward.
For the first time in many years, Pei Zhi showed his outstanding mathematical talent in front of his mother. In a short time, he reassembled the vast amount of data in an exquisite way.
After that, the whole program modification became much smoother.
Pei Zhi agreed to help her monitor the program, and they agreed on some new strategies, such as fixing the start time and using the mobile phone to locate the real-time location, which greatly simplifies the difficulty of prediction.
They discussed all this in the ward, and Pei Zhi's mother even found a computer for them.
Lin Zhaoxi didn't actually believe that a note could change a deep-rooted belief, but maybe it could make a mother who loves her child equally painfully begin to try to understand. It's hard though, and her time is running out.
And Lin Zhaoxi thought, in fact, the time she stayed here was about to come to an end.
—
The road is busy and the bus is coming. The car door opened, and the crowd swarmed.
The people were crowded and quiet, and the scenery outside the window passed by, it was a street she was familiar with but unfamiliar.
In the earphone on one side is the boy's gentle breathing sound, and the originally uneasy journey seems to be much calmer.
She and Lao Lin got off the bus.
In the distance is the road leading to the school. In just ten minutes, she has thought about it countless times.
There is an alley entrance 50 meters ahead, with some forks and dense battery cars.
There are two roads interspersed in the middle, and they are often congested during peak hours. If you go there again, it will be the campus where Lao Lin will give a report.
There should be banners welcoming the participating experts and college students in high spirits.
Together with Lao Lin, she walked there at an even pace.
Pei Zhi has been telling her the result of the predicted journey in an extremely peaceful tone. Lin Zhaoxi listened to his voice and the spatial background behind his voice.
She kept walking, and everything in front of her seemed to fade away under the bright sky.
The world seems to be dissolving at this moment, but the calm faces of Feng and Lao Lin are extremely clear.
500m…
400m…
300m…
Pei Zhi's serious reminder sounded at the same time as the sharp life detector alarm in the background. Countless people rushed into the ward, footsteps came one after another, Lin Zhaoxi bit her fingers, trying not to let herself cry out.
Lao Lin seemed to sense something, and looked at her gently: "Go back to the hospital."
Lin Zhaoxi shook her head at him, pressing the headset tightly with trembling fingers.
"Pei Zhi."
"kindness."
"After attending Comrade Lao Lin's report, I will come back."
"good."
"wait for me."
"I will."
"goodbye."
"goodbye."
The old Pei Zhi should be handed over to the old Lin Zhaoxi.
"I'll accompany you there." Lin Zhaoxi looked at Lao Lin and said so.
Lao Lin looked at him inexplicably, but as if he had sensed something, he rarely stretched out his hand and held her.
They stood together at the traffic lights.
Ahead was the gate of Yongchuan University. She saw 25-year-old Lao Lin pull out his arm and rush out of the gate without hesitation.
When the red light turned green, Lin Zhaoxi grabbed Lao Lin.
A van drove past them.
At the crossroads, the sky was bright and clear, and everything seemed to dissipate like a cloud of smoke.
This is Lao Lin, 41, and her, 16.
It's Lao Lin who is in high spirits, and her who is a toddler.
It was Lao Lin who rushed into the consulting room, and she who just fell to the ground.
Thank you for choosing to be my dad.
