Turning around, Lin Zhaosheng woke up and found Qin Hao lying on the sofa at home, scratching his head.

When he saw Lin Zhaoxi cooking porridge in the kitchen, he yawned and asked, "Then why is Xiao Qin falling asleep on the sofa?"

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

After saying that, Lin Zhaoxi lowered her head with a guilty conscience. Thinking of the intimate contact last night, she couldn't help but feel a little flustered. She wasn't sure whether it was a momentary impulse or whether she had developed a crush on Qin Hao unknowingly 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 in a funny way: "You were already asleep at that time. Let's do it next time. I will definitely call you next time."

"That's pretty much it." Lin Zhaosheng was satisfied and went to wash up.

Lin Zhaoxi couldn't help but shake her head, who is the parent and who is the child?

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

Qin Hao looked at the living room and found that Lin Zhaosheng was watching TV, so he whispered: "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 to

Remind Uncle Lin what he should do or what he should not do."

Lin Chaoxi was moved: "Thank you."

Qin Hao gently took Lin Chaoxi's fleshy palm and said, "I'm seeing you outside."

Lin Chaoxi 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 shamelessly.

Lin Zhaoxi glanced at him: "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 by her, he leaned into her ear and said: "I stamped it last night, so don't give up."

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

Lin Zhaosheng was watching TV when he suddenly scratched his head and walked to the kitchen door: "By the way, I haven't been to work for many days. Is there any problem at work?"

Lin Zhaoxi's hands shook and she almost dropped the plate to the ground. She forced herself to calm down and said, "Oh, aren't you so tired from work that you fell ill? The leader of your unit was afraid that something would happen to you again, so he gave you a long vacation.

Why don't you take a rest at home and enjoy this paid vacation?"

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

When Qin Hao saw this, he smiled and said: "Uncle Lin, you didn't come from time travel. How do you know what happened before?"

"Yeah, how could I forget this?" Lin Zhaosheng suddenly smiled.

After saying that, he continued to watch TV.

Lin Zhaoxi took a deep breath and asked with some worry: "What if my dad has to go to work in a while?"

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

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

Qin Hao shook his head and said: "That's not necessarily the case, it's just that there is no way to cure it with current technology, but what if P=NP is solved?"

Lin Zhaoxi subconsciously looked towards the living room and saw Lin Zhaosheng watching TV attentively. Then he breathed a sigh of relief and whispered: "But this is the only one among the seven major mathematical problems in the world that has no progress at all. My dad has already studied it.

It has not been completed for more than 20 years."

"Even if we prove that P=NP, if we want to expand it into medical clinical practice, I'm afraid my dad won't be able to hold on for that long." Lin Chaoxi burst into tears as she spoke.

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

When Lin Zhaoxi heard this, she immediately looked at Qin Hao with wide eyes: "You mean, the cheese world already has a drug that can treat Alzheimer's disease? But how did you know?"

After Qin Hao thought for a moment, he said slowly: "Actually, I have been walked through before."

"Traveling?" 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 Chaoxi's eyes trembled like an earthquake: "You mean..."

"Yes, I am sealed in this body. Everything that happens in the outside world can be seen and heard. However, my body is not under my control. I can only wait for the foreign consciousness to return to the original world before I can regain control of the body.

control."

Qin Hao's words shocked Lin Chaoxi: "So you were transported through time. Was it Qin Hao from the cheese world who told you that there are drugs to treat Alzheimer's disease in the cheese world?"

Qin Hao nodded: "Yes, in the cheese world, Uncle Lin, Pei Zhi and I, the three of us worked together to prove P=NP. In the fields of mathematics, optimization, artificial intelligence, biology, physics, economics and industry

, there are indeed thousands of NP problems, which arise naturally out of different needs, and effective solutions will benefit us in many ways. Proving that P=NP will mean that all these difficult problems

It can be solved in polynomial time, and some drug manufacturers have developed drugs to treat Alzheimer's disease through this formula."

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

However, Qin Hao held her shoulders: "Calm down first and think about which year we traveled through the cheese world before?"

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

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

"And have you ever thought about how we can come back after traveling through time since we don't have any photos this time?"

Lin Zhaoxi held her hands together, her eyes were distracted and confused. She finally learned that she could fulfill her father's wish, but found that it was simply impossible to accomplish. This was more painful for her than not knowing.

Qin Hao gently hugged Lin Chaoxi's trembling body into his arms and said softly: "Don't get excited yet. Wait until I finish. Since I proposed this plan, I must have thought of countermeasures."

Lin Chaoxi's eyes turned red and she hugged Qin Hao tightly: "I knew you would find a way. Please tell us what we should do to get the medicine."

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

"Yes." Lin Chaoxi nodded gently. He was a wise and brave little boy.

Qin Hao pinched Lin Chaoxi's fleshy cheeks: "Do you still remember the photo of us traveling through the cheese world for the first time? That was what Pei Zhi from the cheese world put in your mailbox."

"What? You mean Pei Zhi from the Cheese World has also been to our Strawberry World?" Lin Chaoxi's eyes widened in disbelief.

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

"You haven't left yet. Do you mean that the Pei Zhi we met that day was actually the Pei Zhi of the Cheese World?" Lin Zhaoxi looked at Qin Hao in surprise.

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

"You've made me confused." Lin Chaoxi's brows knitted together.

Qin Hao gently hugged Lin Zhaoxi 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 inside Strawberry Pei's body, I put that photo just to let you go back and contribute to the experience of the cheese world."

"Experience?" Lin Chaoxi blushed slightly and was very confused.

Qin Haodao: "A person's experience determines who she is, just like you. If it hadn't been for that experience in the cheese world, would you have quit your job as a teacher and taken the postgraduate entrance examination?"

Lin Zhaoxi suddenly shook his head: "So, all of this is controlled by Cheese Pei Zhi behind the scenes? He is 'creating' a strawberry Lin Chaoxi who has experienced traveling through the cheese world?"

Qin Hao nodded: "In a sense, it is indeed like this."

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

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

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

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

"Did Cheese Qin Hao tell you this?" Lin Zhaoxi asked curiously.

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

Lin Zhaoxi took the letter and felt an inexplicable pain in her heart when she saw the words on it.

Looking at Lin Chaoxi'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 stay with you forever, 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 to a distant place."

Lin Zhaoxi cried loudly as she read this passage. The mother who had never appeared in her memory, the mother who had never heard her call her mother, used her life to explain what maternal love is.

After a long time, Lin Chaoxi calmed down: "So, this is the medium through which we travel through the world of cheese?"

Qin Hao nodded: "There were originally three blood stains on it, but now there are two missing. As long as the remaining blood stains are wiped off, you can go to the cheese world."

"But before that, we still need a medium to ensure that we can come back."

Lin Zhaoxi quickly thought: "Is such a thing on Pei Zhi?"

Qin Hao nodded and shook his head: "Pei Zhi has a voice recorder 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, record the above words, and at the corresponding time point, you can

Come back, but this time point is in 2013, so we need to erase the formula first, go back to the time when you were in high school, and leave something unique to this world and with a strong belief in the cheese world."

"When we travel next time, we can use something like this to travel back."

Lin Zhaoxi fell into deep thought: "Something unique and with strong conviction?"

"My father's medical diagnosis?"

Qin Hao thought about it and it seemed that this was Lin Chaoxi's strongest wish at the moment.
