In Yang Lin's life, in addition to his closest relatives, there were two people who had an important impact on his life.

One of them is the master Blackcat, who led him into the hacker circle, Chinese code name Black Cat, one of the top figures in the Chinese hacker circle.

Yang Lin has been under the guidance of his master since middle school, and he has slowly created a little fame in the hacker circle.

To this day, although he is secretly a member of the "Immortal Bird" software cracking team, on the surface, he is more widely known for his trumpet [Wisdom Cube] on the famous encryption and decryption website Kanxue Security Forum, where he has used this trumpet to publish many high-quality original articles, and has even been praised by his master.

However, since the incident a few years ago, Yang Lin has gradually reduced his activities on the forum, and he has focused most of his energy on cracking software to make money.

Supporting himself and his sister and healing his sister's legs has become his biggest goal in life.

As for the other person, it is Lin Qingya, that is, the girl on the background of her computer desktop.

From a certain point of view, Lin Qingya is the benefactor of Yang Lin's brothers and sisters.

Yang Lin once had a happy family, his parents were teachers in a middle school in Jiangcheng County, and he had a younger sister who was two years younger than him.

Five years ago, Yang Lin was admitted to the Department of Applied Mathematics of Jiangcheng University, which ranks among the top universities in China, and in his junior year, his sister was admitted to the same university as him.

At the end of the summer of that year, my father and mother were in a car accident on the way to drive my sister to school in Jiangcheng, and my mother was killed on the spot, and my father and sister were seriously injured.

But this is far from over.

Because his father was a Rh-negative panda blood, Yang Lin hurried to the hospital to donate blood to his father, who was being rescued, but was surprised to find that he had no blood relationship with his parents.

This news was like a thunderbolt from the blue, and it directly stunned Yang Lin.

He never thought that his parents, who had always loved him, were not his biological parents.

But the secret behind this can't wait for the day when it is solved, and after his father rescued him for a day and a night, he finally passed away, leaving only Yang Lin and his sister Yang Ying to rely on each other.

Yang Ying suffered a spinal injury in this car accident, underwent two consecutive surgeries, and the function of her lower limbs only recovered less than 40%, and she can only rely on a wheelchair to travel on weekdays.

The insurance can only cover the cost of surgery, and it is simply not enough to afford the huge cost of later rehabilitation.

During that time, for Yang Lin, who had just entered his third year of college, the pressure from all aspects almost overwhelmed him.

It was also at this time that Lin Qingya suddenly broke into his life.

Lin Qingya is very famous.

As soon as he entered the freshman year, he was recognized as the first school flower of Jiangcheng University by all the good deeds.

And this school flower is not the same as the average Bai Fumei, Lin Qingya has a gentle personality, a lovely temperament, and treats the characters with a sincerity that is difficult to find in ordinary people, and has an excellent reputation among her classmates.

Because of this, in her sophomore year, Lin Qingya was elected as the vice president of the school's student union with a high vote, and her prestige in the school is very high.

After learning about what happened to Yang Lin's brothers and sisters, Lin Qingya organized all the students in the school to donate money to Yang Ying through the student union to help them get through the most difficult stage.

Later, she often went to the hospital to visit Yang Ying, who was depressed, and helped her slowly get out of the pain of losing her parents and paralysis of her lower limbs.

After going back and forth, Yang Lin and Lin Qingya gradually got acquainted, and her sister Yang Ying and her became close friends who talked about everything.

Sometimes fate is so wonderful!

In the process of contacting Lin Qingya, Yang Lin's affection for her increased day by day, and in the end, Yang Lin himself didn't know what kind of feelings he had for Lin Qingya.

Grateful? Love?

Maybe it's a bit of both.

But Yang Lin knows his own family affairs, no matter what the conditions are, he is not worthy of the goddess-like Lin Qingya.

In the four years of college, Lin Qingya has not had any scandals with any male students, even those who claimed to attack Lin Qingya when they first entered the freshman year, and in the end they were silent for no reason.

School rumors say that Lin Qingya has a very deep background.

But Yang Lin has never felt the domineering of the second generation from Lin Qingya, and only the noble temperament that occasionally reveals from the other party can he feel that the other party's background is not ordinary.

It wasn't until later, when Lin Qingya was chatting with her sister, that Yang Lin knew that the goddess already had a fiancé.

Since then, Yang Lin has buried this feeling deep in his heart, and after graduating from college, Lin Qingya stayed in school and became the counselor of Yang Ying's class.

With Lin Qingya by her side, Yang Lin was also relieved to let her sister live in the school, and rented a house in the community near the rehabilitation center, so that her sister could go to physiotherapy on weekends.

Counting up, the two haven't seen each other for a long time.

Originally, he planned to drive to school to pick up his sister today, but he didn't expect Lin Qingya to come over today.

…………

More than an hour later, Yang Lin came back from the supermarket with large bags of food, and as soon as he entered the community, he saw a beige Volkswagen Golf parked downstairs at his house.

A woman in sunglasses bends down and prepares to help a ponytail girl out of the car, while a folding wheelchair is parked next to the Golf.

"Xiaoying!"

Yang Lin shouted, hurriedly ran over, handed the shopping bag in his hand to the woman in sunglasses, and said, "Qingya, help me lift it, let me come!" ”

The woman in sunglasses took the shopping bag, and Yang Lin stepped forward to carefully pick up the ponytail girl and put her in a wheelchair.

"Brother!"

The pony-tailed girl looked up and winked at Chen Xin, revealing a bright smile.

Yang Lin pinched his sister's little face and raised his head to look at the woman in sunglasses.

Lin Qingya's face is still the same.

She is wearing a white cut-out short-sleeved T-shirt top, and the lower body is a slim fashion trouser painted with a black mottled pattern, fair skin, a slender figure, slightly curly middle hair draped over the shoulders, and a pair of wide sunglasses sandwiched between her small nose, playful and cute.

Yang Lin held back the throbbing in his heart and smiled: "Long time no see." ”

Lin Qingya took off her sunglasses and said with a smile: "You haven't seen you for a long time, why don't you come to the school to walk around and meet your old classmates?" ”

Yang Lin smirked, not knowing how to answer for a while.

In front of Lin Qingya, he is always like this.

"Okay, okay, you two don't be polite, act like strangers."

Yang Ying sat in a wheelchair, poked her head and looked at the shopping bag in Lin Qingya's hand, and said, "Brother, what delicious food did you buy today?" The food at school is terrible, but you still make it delicious. ”

Without waiting for Yang Lin to answer, Yang Ying said to Lin Qingya again: "Sister Qingya, don't look at my brother's other things, the cooking skills are absolutely ......."

With Yang Ying gagging on the side, Yang Lin's mood in the face of Lin Qingya was also a lot more relaxed, and the three of them talked and laughed and entered the elevator.

After arriving home, Yang Ying pulled Lin Qingya back to the bedroom, and the two were chattering in the room, not knowing what to say.

Yang Lin entered the kitchen and got busy.

It's just that after a while, Yang Ying shouted again: "Brother, come out, we have something to tell you." ”

"What's wrong?"

Yang Lin came to the living room and found that Yang Ying and Lin Qingya had been sitting on the sofa for some time.

Yang Ying said: "Sister Qingya, you say." ”

Lin Qingya took out a blue disk of Western Digital from the Kun bag she was carrying, and said: "That's the case, two days ago, my computer was accidentally hit by a virus, and as a result, many of the data stored in the hard disk were maliciously read and written many times and then deleted, and the most important thing is that the source program of our School of Information to participate in the ROBOCUP Robot Football Intramural Tournament is also in it." It's less than a month before the start of the game, and it's too late to rewrite a control program, so we found a lot of people who want to recover the data inside, but they haven't succeeded, Xiaoying said that you may have a way, so I want you to try it. ”

Yang Ying also looked at Yang Lin with a look of hope and said: "Brother, it depends on you whether you can succeed this time, I am also a member of the Blue Phoenix team of our School of Information, if we can win the intramural competition, we can represent Jiangcheng University to participate in the ROBOCUP Robot World Cup to be held in the United States in March next year." ”

"RoboCup?"
