[Once you start learning, the time flow will get faster]

[Time in learning = real time * under root number (1-(current learning speed??/C??))]

Among them, C is 300,000 times that of Liu Xin’s learning speed, and is a constant cosmic constant.

With such a profound theory, Feng Dad naturally could not see it from Li Zheng's eyes. He just smiled bitterly and nodded: "What do you want to eat tonight? I'll make it for you."

"Ah...this..." Li Zheng looked at Gui Jianfeng embarrassedly, "How long will it take for you? If not, we will be the next day?"

Gui Jianfeng still had no answer.

I think that's right.

His learning speed may have exceeded C.

In that case, learning relativity will also penetrate into the complex domain, and its time flow rate will become an imaginary number, which will be independent of this universe and become a concept that only exists in theory.

Thinking of this.

"Ah..." Li Zheng rubbed his forehead.

No, I think too much about this today, and I'm afraid I'll be infatuated.

For the first time, he wanted to end his day of study and have a good rest.

As the headache was happening, Feng Dad had already brought two boxes of milk and handed him one box, and placed the other box next to Lin Yujing's head, which was sleeping on his tummy, which was on Li Zheng's legs.

"Mathematical calculations are very painful. If you can't keep up with nutrition, you will have a headache." Feng Dad immediately retreated and kept a polite distance and smiled, "Actually, we've seen it once before."

"Oh? Sorry..." Li Zheng carefully measured it, and he really had no impression.

"During the national math competition," Feng Dad himself took a box of milk and inserted the straw and smiled, "At that time, Feng Feng suddenly called and said he was almost out of reach. I immediately put down my work and took the high-speed train to rush over, but when I entered your room..."

As Feng Dad said, smiling and raising his hand: "The scene is exactly the same as today."

"!!" Li Zheng then realized, "I remembered that we had studied all day and waited for you to leave before we saw the notes you left. It was very rude."

"This, this is actually my third time back today."

“???”

"Haha, it's okay, this is great, I want to thank you." Papa Feng smiled, sucking milk, "Since the competition in the country, he has not been able to "not work". It seems that he has found a new method and seems to have become stronger. I thought he could not stand the IMO, but he still holds it up. Thank you."

"I actually did nothing." Li Zheng rubbed Lin Yujing's head and looked at Gui Jianfeng and smiled, "I got much more from him than I gave him if I hadn't said anything."

"You are humble, I checked it. Your experience and achievements are much stronger than seeing the wind." Feng Dad said, and smiled at Lin Yujing, who was sleeping again, "The results are the same."

"Ha, ha." Li Zheng smiled dryly, "I'm just too greedy. In terms of the most core mathematics, I'm willing to use it as a draft paper for Gui Jianfeng."

"Your words should be modest, but I understand..." Feng Dad shook his head and sighed, "You have learned too deeply, and I can't even see the back... I know I'm selfish, but if possible... I actually... would rather he be a healthy and ordinary person...even if he is stupid..."

Father Feng said as he closed his face sideways: "I'm sorry... Well, I'll prepare what I want to eat."

Li Zheng couldn't help feeling sad.

He had no doubt that for academics and even humans, seeing the wind must be a treasure full of value.

But for father and family, this treasure is not worth mentioning in front of health.

"Thank you for your hard work." After Li Zheng finished speaking, he raised his hand and threw Lin Yujing aside, got up and patted Gui Jianfeng, "Don't forget it, just make a meal for your father this time."

"???" Gui saw that the wind was stagnant and was stagnant for a long time before cursing, "I took advantage of me again! I won't cook for you!"

This situation is a bit out of control.

Li Zheng quickly raised his hand and stabilized his father Feng: "It is a reasonable joke between familiar boys who are fathering each other."

Then he looked at Lin Yujing, who rubbed his eyes and woke up suddenly and found Li Zheng as his father: "Stay sleeping on yours."

Finally, I caught Gui Jianfeng: "You are so good at calculating. In order not to disturb us, your father has been strolling outside for a day and dared not come back. Stop talking, while my little head of Yinghu is here, please respect your father for a meal."

"Ah..." Gui Jianfeng was in a daze for a long time, glanced at the sky outside, and then habitually looked at the small table on the right.

This habit has been a long time. Once he is hungry or tired and can't continue to learn, the table will be filled with prepared food without accident, so that all this seems to be natural and exists like physical laws.

"It's okay." Papa Feng quickly wiped his eyes, "I'll do it, you guys continue..."

Gui Jianfeng had not replied before he could greet Li Zheng's glare.

"Ah...it's still..." Gui Jianfeng had to rub the back of his head and stood up, and said with a side face, "Let's do it today... Li Zheng has a good cooking skills."

Father Feng still refused again, but Li Zheng pushed him over: "You go outside to watch TV, and I won't train us... today."

It is hard to refuse the kindness, and Li Zheng is domineering, so Feng Dad has to really go to watch TV.

Then he pulled Fengfeng and dragged Lin Yujing into the kitchen, asked about their favorite dishes, and sent Lin Yujing to purchase ingredients. Li Zheng listed the cooking steps, followed by Jianfeng to make overall plans, and finally started to meet.

Li Zheng thought that Gui Jianfeng would blame him for being troubled, but when Gui Jianfeng was more serious than what he did, he always tried hard to recall the tastes his father liked for cooking, and constantly reminded Li Zheng of his control over the ingredients.

Before eight o'clock, the hot fish, meat, vegetables and soup were served.

Papa Feng was always praised, but as he praised, his eyes turned red and he stopped talking.

The same is true when you see the wind.

In the end, it turned into a tough chat between Li Zheng and Lin Yujing.

"You leave a fish for people."

"Mmmmm...I was so scared that I was stabbed."

"I deserve it."

"Really... um... it's stuck in my throat."

"Oh? Then I'll suck it out for you."

"It's okay, it's okay."

"Why are you still picking up fish? Leave a mouthful of fish for people!"

During this cycle of eating fish, the atmosphere finally calmed down. Gui Jianfeng also grabbed a piece of fish from Lin Yujing and grabbed it into his father's bowl. He turned his head and squeezed out the words in a very low voice.

"Dad... Thank you for your hard work."

"Hi, why are you doing this?" Feng Dad ate the fish with rice in one bite, with a smile on his face, "What you cook is so delicious. It turns out you have this talent."

"It's not me... it's mainly Li Zheng... I'm much worse than him..." Gui Jianfeng lowered his head and said.

"Where?" Li Zheng glared at the eye and pointed at a large piece of strange-shaped "ginger silk" on the fish with chopsticks. "This ginger silk is cut by the wind and is very imaginative."

Feng Daddy was also floating, and reached out to grab the ginger shredded in his mouth, nodding and said, "Okay, okay, all are good. This ginger shredded shredded is the best, it can drive away the cold."

This is a bit of a struggle.

In order to relieve the embarrassment, Li Zheng quickly grabbed a piece of Lin Yujing: "Come on, eat ginger to drive away the cold."

"I don't...well..."

Seeing Lin Yujing being stuffed with ginger, the father and son both laughed, laughing non-stop.

Finally, while the father and son were watching evening sports news together, Li Zheng left the note of [Tomorrow's discussion] and pulled Lin Yujing away quietly.

The bad news is that nothing has been achieved today.

The good news is that I have been having a happy life today.

But Lin Yujing did not.

She kept thinking that she was sleeping well on her stomach...
