Summer nights always come slowly.

When the family was full and put down the dishes and chopsticks, there was still some afterglow of the setting sun in the sky. Jing Changjia ate slowly, he was alone on the hospital bed holding a thermos cup and sucking slowly, and the others did not urge, just sat around the bed and chatted.

Hearing Yang Heng mention that Feng Zhaoye had come in the afternoon, Aunt Jing immediately said, "Xiao Feng, that kid is here again?" He is so busy and always finds time to come to see Jiajia, you have to cherish this friend Jiajia. ”

"Is it the kid who saved Jiajia?" Jing's mother hurriedly asked, "He's coming to see Jiajia again." ”

Jing Changjia originally only had an ear to listen to their chat, but when he heard them say this, he interjected in surprise: "He saved me?" How can he save it? ”

Jing's mother remembered that on the day she received the news, she was still a little frightened: "The situation is very dangerous after you fall." There were trees under the cliffs, and it was raining again. The drone infrared search didn't find you at first. ”

"Not really." Aunt Jing followed up and said, "After looking for you for a day and a night, your mother is going crazy." ”

But it's also very weird.

Although the school military training should train the students, it will not arrange any dangerous places. That mountain is the mountain in the city, the altitude is only more than 2,000 meters, the whole mountain has a high degree of development, and there are many characteristic farmhouses on both sides of the mountain road, which is a place where people in the city often go to play.

Jing Changjia's search and rescue difficulty when he fell from the cliff should not have been so high.

But the drone and the search and rescue team searched in the rain for a day and a night, but they didn't see anyone.

Mother Jing and Aunt Jing glanced at each other, tacitly skipped this weirdness that made them chill, and only said calmly: "It was raining at that time, and the sight was not good." It was the small envelope that went down the cliff with a safety rope to find you. ”

"The drones didn't find me?" Jing Changjia bowed thoughtfully, "It seems that the rain will affect the search and rescue very much." ”

"That's true." Jing's mother said, "But fortunately, you are slowly getting better." When you are discharged from the hospital, we will go to thank you for the small envelope. ”

"Okay." Jing Changjia replied casually, and said in his mind, "System, this is your fault?" ”

"When the host was about to be bound, the host had an accident and its life status was unknown. The system has to expend a lot of energy to maintain the host's life. The system replied, "It has been calculated that this may be one of the causes of an unknown failure that causes space-time distortion." ”

Jing Changjia was stunned when he heard this: "In this way, you also saved me." ”

He paused and said seriously, "Thank you." ”

"You're welcome, host. As long as you start live streaming as soon as possible, it is the best thank you to the system. ”

Jing Changjia bent his eyebrows: "Okay." ”

As a condition negotiated from the beginning, Jing Changjia did not resist the live broadcast. After all, he has lived in the Dahong Dynasty for more than ten years, and now that he returns, the live broadcast may become his only connection with the Hongchao.

It's just that in his previous assumption, it would be a good time for the live broadcast to wait for him to recover and be discharged from the hospital.

But now that the system is so demanding energy, maybe he needs to think differently.

His thoughts were racing, but life was still going according to plan.

Sweating profusely every day and working hard to rehabilitate, when he was free, he grabbed a pen to write and draw in a new book, and occasionally made a cameo appearance as Yang Heng's tutor, taking on the responsibility of making up lessons for this little cousin who was not in a good mood.

Yang Heng never expected that such a relaxed summer vacation with no homework at the beginning of the high school would still need to make up classes. But the one who caught him to make up for the class was his weak, pitiful, helpless brother who couldn't leave people at all, and he could only wrinkle a bitter gourd face and honestly stay in the ward to attend classes.

It took a morning to slowly finish writing a high school test paper, Yang Heng worms squirmed and pasted to Jing Changjia's side, and looked at Jing Changjia's book with a probe.

The book he bought had already used many pages, and when he looked at it, it was full of ghost drawings, and there was not a single symbol that he could understand.

"Brother, are you exercising your fingers?" Yang Heng asked.

After spending so many days with his brother in rehabilitation, he understood that writing was a finer hand movement than grasping. Looking at his brother's book, it is obvious that the road to rehabilitation has a long way to go.

Jing Changjia said with a smile: "I'm making money." ”

"What kind of money can you make with this ghost drawing?" Yang Heng snorted, "You can only sell it to me." For your sake, I can pay a hundred! ”

"Then you're out of the blue." Jing Changjia said calmly, "Someone is willing to pay a million Buigogin. ”

Buigo is a country across the ocean, and its currency has a ratio of 1:7 to Longxia. One million Buigo Gold, that's seven million Dragon Summer Coins.

Yang Heng didn't take his brother's words seriously at all, and snorted a few times against his brother, and then put forward an application to play the game.

Jing Changjia sighed: "You study hard now and work hard for the exam." When you get into graduate school, you might be able to be my student. If you don't work hard now, you won't even be able to get into my school, what can you do? ”

"Brother, why don't I find a doctor to show you your brain." Yang Heng lay on the bed and sulked, "With your current body, maybe when I take the university entrance examination, you haven't graduated yet!" ”

Jing Changjia knocked him on the head with a pen: "Go play, don't bother me." ”

Yang Heng cheered, ran to the sofa in the ward and shrunk up to play with his mobile phone, Jing Changjia regained his attention back to his notebook.

His handwriting is really not easy to read now, and if you show it to others, you will probably think that this is some kind of doctor's handwritten prescription list. Even he took the time to distinguish himself before he could continue to write.

Although anyone who looks at it thinks it is a ghost painting talisman, Jing Changjia draws it very seriously. Within a few days, a new book was filled with him. Seeing this, Yang Heng simply went to buy him ten sketchbooks and asked him to paint them wholeheartedly.

The new sketchbook is very large, and Jing Changjia is more comfortable to use. He also deliberately controls his fingers when using the pen, and after a sketchbook, the handwriting has become much clearer.

When Feng Zhaoye came back, Jing Changjia had just finished writing a sketchbook and was changing the book.

"Can I take a look?" Feng Zhaoye asked him.

"Whatever you want." Jing Changjia handed him the old book.

Feng Zhaoye took the sketchbook and carefully read the ghost drawings page by page. Jing Changjia let him go, and he opened a new book and continued to write.

The marks in the old sketchbook were not even the same size at first, and there were many small wavy lines of unknown meaning in the handwriting. Feng Zhaoye knew that it was a trembling trace of enduring pain.

The further back you turn, the neater the handwriting becomes. They began to become uniform in size, and even shivering was much less.

This whole book is a trace of Jing Changjia's efforts.

Feng Zhaoye turned to the last page, stared at the handwriting and pondered for a long time, and then turned forward page by page.

It wasn't until the book returned to the first page that he cautiously spoke: "Hodge's conjecture? ”

Jing Changjia's immersed thoughts were interrupted by the voice, and he stopped writing in surprise: "How did you recognize it?" ”

"Guess from back to front." Feng Zhaoye said, "The handwriting on the back of you is very clear. ”

Jing Changjia couldn't help laughing: "You are really a genius who recognizes handwriting." He looked at Feng Zhaoye seriously with crooked eyebrows, and said, "And your changes are really big." Can't blame me for not recognizing you. ”

When he was in high school, Feng Zhaoye was a peacock with only an open screen, and the whole person was arrogant and flamboyant, with "Lao Tzu is the first in the world" written all over his body.

And now, all his outward releases have become inward. Even his height has been rising step by step, from being one line higher than Jing Changjia in high school to being half a head higher now.

"People always grow up." Feng Zhaoye said casually, "How could you think of arguing this?" ”

"Practice your brain." Jing Changjia also replied casually, "If you are lucky and hit the big luck, then you will win the lottery." ”

Feng Zhaoye looked at him seriously: "Lack of money? ”

Jing Changjia just smiled.

The king of Yunzhong County has suffered all kinds of hardships at the beginning, but he has never suffered from lack of money. Now that he has returned home, Jing Changjia has to admit that his family is still quite short of money.

Although the school bears the medical expenses, he is completely dependent on his family to take care of him in the hospital, and his parents once wanted to sell the restaurant they have been running all their lives, and the fact that he was hospitalized also gave the family a lot of burden.

Seeing that he didn't answer, Feng Zhaoye changed the subject: "I think your train of thought is a little interesting." As he spoke, he flipped the notebook to the middle: "You have read Professor Wilson's paper, and this part of the computational argument was published in the annual report of mathematics two years ago. His idea is to start from the four-color conjecture and assume the construction of an infinite number of contiguous regions......"

Jing Changjia's eyes lit up when he heard it: "Manifold? ”

"Yes." Feng Zhaoye took out his mobile phone and searched for the paper, "Take a look." ”

Jing Changjia took the phone and looked at it carefully. Then he grabbed the new book and solemnly put pen to paper.

His mind was extraordinarily engaged, and the people who came in and out of the ward were casually dismissed by him. It wasn't until his unblocked train of thought got stuck again that he found that it was already dark outside, Feng Zhaoye had left at some point, and even Yang Heng, who was guarding him, had been replaced by his mother.

"Jiajia is done?" Jing's mother was settling accounts on the sofa, and when she heard him putting the notebook, she immediately got up and walked to the bedside, "Are you hungry?" Let's eat something first. ”

She carefully put away the notebook, and set up a small table next to the bed, before handing the thermos cup to Jing Changjia on the side.

Jing Changjia didn't feel hungry at all when he put in it, and at this time, when the food fell into his stomach, he realized that he was about to be hungry.

The system took the opportunity to chatter in his mind to start the live broadcast, and seeing that Jing Changjia didn't react at all, he had to change the topic again: "I don't understand why you are stumbling on math problems." I thought you'd be more inclined to apply physics or materials chemistry. ”

These two courses are also the two subjects that Jing Changjia has learned the most in the future world. It always thought that Jing Changjia asked to bring things back in order to devote himself to these two fields.

As a result, he woke up for more than a month, but Jing Changjia has been struggling with math problems!

"System, human beings are not high-dimensional beings like you." Jing Changjia said kindly, "The only thing we can create while lying in bed is mathematics and poetry." ”
