A few days later, Lin Zhaosheng woke up and found Qin Hao lying on the sofa at home, scratching his head.

Seeing Lin Zhaoxi cooking porridge in the kitchen, he yawned and asked, "Then why did Xiao Qin fall asleep on the sofa?"

A trace of panic flashed across Lin Zhaoxi's face: "Oh, last night we went to eat supper, he drank some wine and fell asleep at our house."

After finishing speaking, Lin Zhaoxi bowed her head guiltyly, thinking of the intimate contact last night, she couldn't help feeling a little flustered, and she didn't know if it was impulsive, or if she had unknowingly developed a good impression of Qin Hao in the cheese world.

Lin Zhaosheng was a little jealous: "Why didn't you call me when you went to have supper?"

Lin Zhaoxi comforted her with a funny face: "You were already asleep at that time, next time, I will definitely call you next time."

"It's not too bad." Lin Zhaosheng went to wash up satisfied.

Lin Zhaoxi couldn't help shaking her head, who is the parent and who is the child.

After breakfast, while washing the dishes, Lin Zhaoxi asked curiously: "By the way, I heard you said yesterday that you are working on an artificial intelligence project?"

Qin Hao looked into the living room and found that Lin Zhaosheng was watching TV, so he said in a low voice: "Well, I plan to make a companion artificial intelligence robot, so that I can remotely see Uncle Lin's condition through the camera, and also use the artificial intelligence program Remind Uncle Lin what to do, or what not to do."

Lin Zhaoxi was moved: "Thank you."

Qin Hao gently took Lin Zhaoxi's fleshy palm: "It's gone."

Lin Zhaoxi struggled in a low voice, but couldn't break free. She blushed and said, "I'm still not used to it."

"Then get used to it slowly." Qin Hao said cheekily.

Lin Zhaoxi gave him a sideways look: "Don't make trouble, I won't be able to wash the dishes."

Only then did Qin Hao let her go, and when he passed behind her, he leaned into her ear and said, "It was stamped last night, don't even think about throwing it away."

Lin Zhaoxi directly pushed Qin Hao out: "Don't be gross, hurry up and don't delay me doing the dishes."

Lin Zhaosheng was watching TV, suddenly scratched his head, and walked to the kitchen door: "By the way, I haven't gone to work for many days, so there won't be any problems with the unit?"

Lin Zhaoxi shook her hands and almost dropped the plate on the ground, she forced herself to calm down and said, "Oh, you are so tired from work that you fell ill, the leaders of your unit are afraid that you will have another accident, so they gave you a long vacation, let You rest at home first, this paid vacation, can't you enjoy it?"

Lin Zhaosheng patted his forehead: "Why don't I have any impression?"

Seeing this, Qin Hao smiled and said, "Uncle Lin, you are from time travel, how do you know what happened before?"

"That's right, how could I have forgotten this?" Lin Zhaosheng suddenly smiled.

Then he continued to watch TV.

Lin Zhaoxi let out a long breath, and said worriedly, "What if my dad has to go to work after a while?"

Qin Hao comforted: "This panic will be exposed sooner or later. When Uncle Lin recalls it, he shouldn't be too irritated. Let's think about how to cure Uncle Lin."

"But, there is no cure for Alzheimer's disease at all." Lin Zhaoxi said with red eyes.

Qin Hao shook his head and said, "That's not necessarily the case, it's just that the current technology can't cure it, but what if P=NP is solved?"

Lin Zhaoxi looked towards the living room subconsciously, and saw Lin Zhaosheng was concentrating on watching TV, so he breathed a sigh of relief, and said in a low voice, "But this is the only one of the seven major math problems in the world that has not made any progress at all. My dad has already studied it. For more than twenty years, it has not been completed."

"Even if we prove that P=NP, I'm afraid my dad won't be able to last that long if we want to expand to clinical medicine." Lin Zhaoxi was already in tears as she spoke.

Qin Hao waited for her mood to calm down, and then slowly said: "The Strawberry World can't do it, what about the Cheese World?"

Lin Zhaoxi widened her eyes and looked at Qin Hao when she heard the words: "You mean, Cheese World already has a medicine that can treat Alzheimer's disease? But how did you know?"

After thinking for a while, Qin Hao said slowly, "Actually, I have been passed through before."

"Walk through?" Lin Zhaoxi looked at Qin Hao in shock.

Qin Hao said unhurriedly: "Have you ever thought about a question? When we traveled to the cheese world, where did we go in the cheese world?"

Lin Zhaoxi's eyeballs trembled like an earthquake: "You mean to say."

"That's right, it is sealed in this body. Everything that happens outside can be seen and heard, but the body is not controlled by itself. Only when the foreign consciousness returns to the original world can it regain control of the body. of control."

Lin Zhaoxi was shocked by Qin Hao's words: "So you were transported through, and it was Qin Hao from Cheese World who told you that there is a drug for Alzheimer's disease in Cheese World?"

Qin Hao nodded: "That's right, in Cheese World, Uncle Lin, Pei Zhi and I, the three of them worked together to prove that P=NP, in the fields of mathematics, optimization, artificial intelligence, biology, physics, economics and industry , there are literally thousands of NP problems that arise naturally out of different needs, and efficient solutions would benefit us in many ways. Proving that P=NP would imply that all of these hard problems It can be solved in polynomial time, and some drug manufacturers have developed drugs for the treatment of Alzheimer's disease through this formula."

"Then what are we waiting for? Go erase the formula, and then go to Cheese World to buy the medicine back." Lin Zhaoxi said and dragged Qin Hao to the lighthouse.

However, Qin Hao pressed her shoulder: "Calm down first, think about the year we crossed the cheese world before?"

"2006?" Lin Zhaoxi blurted out, and quickly realized: "You mean, those two formulas can only bring us back to the past?"

Qin Hao nodded: "It's very possible that these two formulas represent your regrets about the past. If you can't forget them, there will be echoes. I guess, this may be one of the factors that allowed us to travel to the world of cheese."

"And have you ever thought about it, we don't have photos this time, how do we come back after traveling through the past?"

Lin Zhaoxi clasped her hands together, her eyes were slack, and she was already in a mess. She finally found out that she could live up to her father's wish, but found that it was impossible. This made her more painful than not knowing.

Qin Hao gently hugged Lin Zhaoxi's trembling body into his arms, and said softly, "Don't get excited, wait until I finish speaking, since I proposed this plan, I must have thought of a countermeasure."

Lin Zhaoxi's eyes turned red, and she hugged Qin Hao tightly: "I knew you would have a solution, tell me quickly, what should we do to get the medicine."

Qin Hao wiped away the tears from the corners of her eyes, and said softly, "Do you still remember Pei Zhi from Cheese World?"

"En." Lin Zhaoxi nodded lightly. He was a wise and brave little boy.

Qin Hao pinched Lin Zhaoxi's fleshy cheeks: "Do you still remember the photo of us traveling through the Cheese World for the first time? It was put in your mailbox by Pei Zhi from the Cheese World."

"What? You mean that Pei Zhi from Cheese World also came to our Strawberry World?" Lin Zhaoxi's eyes widened in disbelief.

Qin Hao nodded: "Not only has he been here, but he has never left."

"I haven't left all this time. What do you mean, the Pei Zhi we met that day is actually the Pei Zhi from Cheese World?" Lin Zhaoxi looked at Qin Hao in surprise.

Qin Hao shook his head and said, "No, that is indeed Pei Zhi from Strawberry World."

"You've confused me." Lin Zhaoxi frowned.

Qin Hao put his arms around Lin Zhaoxi gently, and joked: "It's not because you are too charming. Pei Zhi from the Cheese World has always been obsessed with you, so he thought of a way to travel to the Strawberry World where we are. He used hypnosis Lurking in the body of Strawberry Pei, posting that photo is to let you go back and contribute to the experience of the cheese world."

"Experience?" Lin Zhaoxi blushed slightly and was very puzzled.

Qin Hao said: "A person's experience determines who she is, just like you, if it weren't for the experience in the cheese world, would you quit your job as a teacher and take the postgraduate entrance examination?"

Lin Zhaoxi shook her head suddenly: "So, Cheese Peizhi is manipulating all of this behind the scenes? He is 'creating' a Strawberry Lin Zhaoxi who has the experience of traveling through the world of Cheese?"

Qin Hao nodded: "In a sense, it is true."

"Then he did all this just to meet me?" Lin Zhaoxi asked in disbelief.

As he said that, he got hit on the forehead, Qin Hao said angrily: "What do you think? He must want to become Strawberry Peizhi, and then live with you forever!"

Lin Zhaoxi rubbed her forehead in embarrassment: "Oh, what should we do now?"

Qin Hao directly dragged Lin Zhaoxi to the lighthouse, and then smashed open the wall engraved with the formula. Inside was an iron box, and after opening it was a piece of letter paper.

"Cheese Qin Hao told you all this?" Lin Zhaoxi asked curiously.

Qin Hao could only say silently in his heart, sorry brother, and then nodded.

Lin Zhaoxi took the letter paper, seeing the words on it, her heart ached inexplicably.

Seeing Lin Zhaoxi's suspicious eyes, Qin Hao nodded: "This is what your mother left you."

It says on the letter paper.

"I love you, although I have only seen you once, I want to be with you all the time, but I have to leave, you have no memory of me, I am not sorry, don't have any imagination about me, imagination will bring sadness, I'm just an ordinary mother who went far away."

Lin Zhaoxi looked at this passage and burst into tears. The mother who had never appeared in her memory, the mother who had never heard her call mother, used her life to explain what maternal love is.

It took a long time before Lin Zhaoxi calmed down: "So, this is the medium through which we travel through the world of cheese?"

Qin Hao nodded: "There used to be three bloodstains on it, but now there are two missing. As long as you wipe off the remaining bloodstain, you can go to the world of cheese."

"But before that, we need a medium to make sure it can come back."

Lin Zhaoxi quickly thought: "Is this something on Pei Zhi?"

Qin Hao nodded and shook his head again: "Pei Zhi has a recording pen in his hand, and there is a recording on it, as long as you find Uncle Lin and Pei Zhi's father in Cheese World, and record the above words, at the corresponding time node, you can Come back, but this time point is in 2013, so we need to erase the formula first, go back to when you were in high school, and leave something unique to this world with a strong belief in the cheese world.”

"When we travel next time, we will use this thing to travel back."

Lin Zhaoxi fell into deep thought: "Something that is unique and has a strong belief?"

"My dad's medical certificate?"

Qin Hao thought for a while, and it seemed that this was Lin Zhaoxi's strongest wish right now.

"However, this is just my guess, and it may not be successful. We may always be trapped in the cheese world."

Lin Zhaoxi said without hesitation: "No matter what, I will definitely save my dad."

Afterwards, Qin Hao brought Lin Zhaoxi to the boxing gym.

"Pei Zhi, I need the recording pen in your hand, can you give it to me?"

Pei Zhi looked at Lin Zhaoxi in shock: "How did you know about the recorder?"

Qin Hao stared into Pei Zhi's eyes, and said slowly: "Cheese Pei Zhi, meeting old friends, this is not how you treat guests."

Pei Zhi suddenly closed his eyes and fell to the floor. Lin Zhaoxi was startled. After a while, Pei Zhi got up and stretched out his hand towards Qin Hao.

"Strawberry Qin Hao, Strawberry Lin Zhaoxi, long time no see."

Lin Zhaoxi looked at Pei Zhi hesitantly: "Are you really Cheese Pei Zhi?"

Cheese Pei Zhi smiled happily: "Of course, in order to see you again, I gave up everything in the world of Cheese."

Qin Hao directly interrupted: "Pei Zhi, I think I told you once that you and Strawberry Lin Zhaoxi are two parallel lines that never intersect, and there is no possibility that they will ever meet."

Cheese Pei Zhi lifted the corners of his mouth and spread his hands: "But I still came to your world."

"But Lin Chaoxi will not belong to you." Qin Hao said coldly.

Lin Zhaoxi also took the initiative to hold Qin Hao's hand: "That's right, I'm with Qin Hao, Pei Zhi, you shouldn't have come, you should go back to the cheese world, that's your world."

Cheese Peizhi said stubbornly: "No, I won't go back. In order to be able to come to your world, I gave up everything. I can't lose you again."

Lin Zhaoxi was still about to say something, but Qin Hao came directly behind Pei Zhi and knocked him out with a knife.

"Why are you standing still, go open the door."

Lin Zhaoxi was a little dumbfounded: "This is also okay?"

Qin Hao said: "What's wrong? Just bring him back to the cheese world. He doesn't have a medium in his hand, so he can't come to the strawberry world. After a long time, he will naturally figure it out."

Lin Zhaoxi thinks so too, although this is a bit cruel to Cheese Peizhi, but that is his world, so that Strawberry Peizhi can live a normal life and kill three birds with one stone.

When he came to the lighthouse, Qin Hao carefully recalled the process of Cheese Peizhi's crossing. First, he returned home with Lin Zhaoxi, found Lin Zhaosheng's medical certificate, and planned to hide it. Lin Zhaoxi took the medical certificate and looked at Lin Zhaosheng who was already asleep. , Inexplicably, the nose was sore, and the tears couldn't stop falling down, and a few tears were also left on the medical certificate.

Lin Zhaoxi quickly hid the medical certificate in the wooden box in her room, and calmed down: "Let's go."

When he arrived at the lighthouse, Qin Hao woke up Pei Zhi. After confirming that it was Cheese Pei, Lin Zhaoxi began to wipe the formula on the wall. Under the horrified eyes of Cheese Pei Zhi, the consciousness of the three began to freeze.

It took an unknown amount of time before Qin Hao regained his consciousness and found himself on the school basketball court, where a group of girls were looking at him affectionately.

At this moment, a figure ran towards Qin Hao and hugged him.

"Oh~~~"

Immediately, the whole playground became a sensation. On the one hand, a male god with Qin Hao’s qualifications has a lot of fans. Sneaking around for fear of being discovered, hugging each other openly in broad daylight is simply a provocation to the school rules.

"Qin Hao, Lin Zhaoxi, what are you doing?" the dean roared angrily.

Only then did Lin Zhaoxi realize: "Are we going back to our high school days in the world of cheese?"

Qin Hao dragged Lin Zhaoxi and ran away, the teaching director was furious behind him, Lin Zhaoxi giggled, she had never had such an exciting experience when she was a girl who followed the rules.

"But in this way, it won't bring trouble to Cheese Lin Zhaoxi?"

Qin Hao shook his head: "Don't worry, Lin Chaoxi in this world knows what you want better than you."

According to the original play, Lin Chaoxi was absent from the college entrance examination, and she joined the entertainment industry as a manager, and quickly made a name for herself in the entertainment industry. After confirming that Cheese Peizhi liked Strawberry Lin Zhaoxi instead of herself, she didn't bother at all, and lived out her life. own appearance.

Lin Zhaoxi and Qin Hao returned to Lin's house and found that the old Lin in Cheese World had changed a lot compared to before. Apart from his long hair, he stopped riding motorcycles, and he didn't look for girls anymore. The relatively stable job is probably also a sacrifice made to take care of Lin Chaoxi.

When she came to Lin Zhaoxi's room, she opened the box and found that the medical certificate was indeed there. Lin Zhaoxi was overjoyed and couldn't help hugging Qin Hao.

Lin Zhaosheng was unhappy: "Both of you, be careful, I'm still here."

The two smiled at each other.

But at this moment, Cheese Peizhi came and asked angrily, "Why did you bring me back?"

"You belong here." Lin Zhaoxi looked at him calmly.

Cheese Pei Zhi looked at her: "Will you stay?"

Lin Zhaoxi shook her head slowly: "I don't belong here."

"My recorder is missing, did you guys get it? What if I ruin your plan and don't let you go back?" Cheese Pei Zhi gritted his teeth.

Qin Hao said slowly: "Uncle Pei definitely wants you to stay, you can't stop us."

Cheese Peizhi closed his eyes in pain. After a long time, he forced out a smile that was uglier than crying at Lin Zhaoxi: "Can we still be friends in the future? I don't want to leave a bad impression in your heart."

"No, you will always be the brave and upright Cheese Pei Zhi." Lin Zhaoxi smiled and stretched out her hand.

Cheese Peizhi couldn't hold back any longer, shook hands with Lin Zhaoxi lightly, and ran out without looking back.

Lin Zhaosheng wondered for a while: "What happened to everyone today?"

Lin Zhaoxi and Qin Hao didn't hide anything, they told about Lin Zhaosheng's situation in Strawberry World, and Cheese Lin Zhaosheng naturally agreed to help them return to Strawberry World.

"Dad, you don't doubt the travel we're talking about?" Lin Zhaoxi was a little puzzled.

As a result, Cheese Lin Zhaosheng uttered a piece of news that shocked Lin Zhaoxi: "Actually, I also traveled through another world. In 1995, when your mother had a difficult labor, I went to the hospital."

"So, the reason why I didn't become an orphan in Strawberry World is because you are making up for the regret in Cheese World?"

Just before going back, Qin Hao and Lin Zhaoxi made up for the shortcomings of adolescence, and their relationship became stronger.

In February 2013 in Cheese World, Qin Hao and Lin Zhaoxi successfully returned to Strawberry World with the help of Cheese Pei Donglai and Cheese Lin Zhaosheng.

After returning to Strawberry World, Qin Hao and Lin Zhaoxi wiped off the bloodstains on the letter without stopping, and they came to the future of Cheese World.

The world's science and technology is developing very rapidly, and the special medicine for Alzheimer's disease has indeed been released. After buying two full courses of treatment, Qin Hao and Lin Zhaoxi took the medical certificate and prepared to travel.

In the end, after trying for a long time, there was no reaction at all. Lin Zhaoxi finally got the special medicine, but couldn't go back. She was so anxious that she burst into tears. At the moment when the tears fell on the medical certificate, Qin Hao and Lin Zhaoxi's thinking stagnated again .

When I came back to my senses, I had already returned to the strawberry world.

"Old Lin, you are saved."

At this time, Lin Zhaosheng thought that he had traveled back from 1996, and refused to admit that he had Alzheimer's disease.

"Don't be kidding, how can a math genius like me get Alzheimer's?"

However, he fainted as soon as he got excited, Qin Hao and Lin Zhaoxi hurriedly gave him medicine.

Not to mention, the medicine really worked. After a course of treatment, Lin Zhaosheng really recovered.

Since then, Lin Zhaoxi was in the process of postgraduate entrance examination, because Lin Zhaosheng was involved in a plagiarism scandal before, and was made things difficult by several professors from Sanwei University. Qin Hao directly submitted Lin Zhaosheng's paper on P=NP to the world-renowned mathematics magazine [Mathematics Annual]. Then it was published in the "Annual Journal of Mathematics", which caused a sensation all over the world.

Not only did Lin Zhaosheng get rid of the suspicion of plagiarism, but he also made Lin Zhaosheng a mathematician attracting worldwide attention.

Qin Hao also became an expert in the field of artificial intelligence and robotics by virtue of his research on artificial intelligence. In the second year after Lin Zhaoxi was admitted to graduate school, the two got married. After Lin Zhaoxi graduated from graduate school, he gave birth to a boy.

In the blink of an eye, after sending Lin Zhaoxi away, Qin Hao also left the world of genius Basic Law.

"System, what is the next world?" After returning to the main world, Qin Hao opened his eyes and asked.
