"I want to learn, I want to learn!" Tang Qingying took the lead in raising his hand.

"Well, before that, you need to tell me why you want to live forever, for any reason, just if you want to live longer, you don't want to die. Cheng Yun said.

"I want to grow old with my brother-in-law!"

Tang Qingying's face was filled with excitement, and the fire clouds in the sky were reflected in his big shining eyes, as if there were two flames.

She thought, if she can live for a long time, she can survive Tang Qingyan even if she survives, right?

Even if she is allowed to live for decades and does not fight with her for the time being, she will only temporarily foster her brother-in-law with her...... What are you thinking, you can't let you do it for a minute!

However, Cheng Yun did not answer.

Until Tang Qingying asked tentatively, "Brother-in-law?"

Cheng Yuncai came back to his senses, shook his head and said: "Your kind of thinking is very immature, most of the likes when you are young and ignorant can't be counted, and even if two people are together, or even married, there are many people who eventually part ways." And once you embark on this path, your life changes, you have to think clearly about what you are going to change this life for, and you have to understand what your life will become when you have a lifespan that surpasses everyone around you. ”

Tang Qingying suddenly became serious: "I'm very serious! And as long as my brother-in-law is here, I don't care about anything! I'm not afraid of anything!"

Cheng Yun smiled.

A young girl immersed in love...... It's synonymous with all goodness!

He didn't say anything, anyway, he had every right to let anyone who crossed paths with him gain immortality, which can be said to be a special honor, and it can also be said to be the treatment he deserves as a friend of the king of the universe.

The reason why we have to ask so once is just a manifestation of responsibility.

Soon he looked at Cheng Yan again: "What about you?"

Cheng Yan turned his head and glanced at him quietly, swallowed his saliva, and pretended to be serious: "You say, can people a few decades ago imagine what the world is like now?"

Tang Qingying really thought about it seriously.

If it were in the developed countries of the West, the appearance of the city today would probably have been laid decades ago, and even in the Qing Dynasty, London was already a high-rise building, but there is still a huge difference between a few decades ago and now.

The ubiquitous Internet, people use video calls, and the processing power of a thousand-dollar machine can beat a military computer the size of a house a few decades ago.

People travel with shared bicycles, people work as anchors at home, and people use numbers to search for small yellow films.

Perhaps decades ago, the Great Power had already imagined modern technology, but it would never have imagined the application of these technologies.

"Can't!"

"What about the people of hundreds of years ago, and what does the future look like in their eyes?"

"They can't imagine what the modern world is like, the world is a fantasy for them. Tang Qingying answered Cheng Yan's question, but she added, "Except for those traversers." ”

"Can you imagine what it will look like in a few decades?"

"Can't!"

Tang Qingying couldn't have imagined the shared bicycles all over the street a few years ago, and he couldn't have imagined the era of smart machines when he was in junior high school.

And for people like Cheng Yan, the temptation of the future world is great for her: "So I ......"

"Wait!"

Cheng Yun interrupted Cheng Yan, and he said helplessly, "I'm sorry I asked if you want to learn, if you want to learn, I'll teach you, and I haven't asked you why you want to learn." ”

“！！！”

"Hmm, why do you have that expression!"

"I'm saying it so obvious!"

"What do you mean?"

“！！”

Cheng Yan turned his head directly.

Of course, Cheng Yun can't help her, and any qualified parent can't help the child who is angry with him, so Boss Cheng pursed his lips and said, "Okay, I roughly understand what you mean, but I still can't agree to you so quickly, this is responsible for you." Secondly, I have a few points that I need to make clear. ”

"What?"

"First, no matter how long you live, you can't live as long as I do. Cheng Yun glanced at Tang Qingying.

"How long can you live?"

"Why!?"

"This question is meaningless, anyway, I will live longer than you, and I will live when you die, and you don't know how long I live. Cheng Yun pretended to be relaxed.

Cheng Yan fell silent.

Tang Qingying was also stunned, she muttered: "I also said that when I get old, I will push you to go for a walk by the river, it seems that you are going to push me......"

Cheng Yun: "??"

Cheng Yan's mind was also distracted by her all of a sudden, and she turned her head and said, "What kind of brain circuit are you!?"

Tang Qingying sighed and became normal: "Brother-in-law, how cruel you are......!

Her eyes widened suddenly, as if she thought of something fearful: "Then what if I'm old and not so beautiful, and you're still very young, brother-in-law?"

Without waiting for Cheng Yun to answer, she immediately said, "Brother-in-law, do you have any way to keep people young forever?"

Cheng Yun thought for a while and said, "This is simple. ”

In his impression, this problem has been basically solved in the Kunzhen world, after all, 'women's youth' is a field with great value. And like the goddess Liu, theoretically speaking, if they are not disposed of, they will be like this until they die. Judging from these points, at least this is not a very difficult problem, maybe they don't need to study it themselves, and the earthlings will have solved this problem after living for a thousand years.

"That's good, that's good!"

"What's the second point?" asked Cheng Yan.

"Second, this is a very esoteric subject, a very complex learning and operation process, and it is not as simple as simply learning something or getting something like a health formula, it will take up a lot of your energy and make you feel very distressed. Overall, it's much harder than what you've been reading for more than a decade, and it will continue for many years. Cheng Yun knows that many people have a hard time even reading, and after the college entrance examination, they celebrate liberation and have been going downhill ever since, if such a person still thinks that he can go far on the road of cultivation, it is obviously an illusion. Just like some computer students think that it would be good to apply for art at the beginning, and those who study art think that they would be good if they studied literature in the first place, in fact......

These people are not all, at least most.

For example, Cheng Yun himself, he doesn't want to practice very much, as if he was doing homework in junior high school......

In this regard, Cheng Yan was expressionless.

As a gifted girl who has had a great interest in all kinds of knowledge since she was a child, she is definitely one of those minorities.

As a former bad girl, Tang Qingying was a little apprehensive, she realized that this didn't seem to be the same as what she watched in the anime, and at this time she recalled the fear of being dominated by textbooks in junior high school and high school......

But soon she shook her head, shook off these thoughts, and reasserted herself: "I'm smart too!

Cheng Yan darkened his face: "Just say what you say, don't take me." ”

Tang Qingying turned his head angrily: "Really! I was still at the bottom of my grade in my sophomore year of high school, I didn't know how to learn and didn't know how to learn, if it weren't for my father's relationship, I wouldn't know that I was expelled many times, guess how I got into 985 in a year?"

Cheng Yan's face was calm: "As a person who is better at science and always likes to read extracurricular books in class, guess how I got the top liberal arts in Yizhou Province?"

Tang Qingying: "The wind is blowing......"

Cheng Yun waved his hand and said, "Okay, if you want to fight back, there is a third point." I'm going to give you a month to think it through, and if you still insist on that answer after a month, I'll give you access to it, but you can't get it out. Because it is the knowledge that countless universes and countless civilizations dream of, this knowledge can make them easily reach the peak of civilization and have a huge impact on the 'cosmic ecology'. ”

"That's a ...... Bragging rights!"

"It's amazing, it's amazing!"

The two reacted very differently.

At this time, the wind did blow, blowing the surface of the lake, and the reflected moon and sparse stars also became blurred, so Cheng Yun got up and said, "I won't tell the story today, give you a little time to digest it, and go back." ”

Cheng Yan did not object.

She glanced at the little Lori, but found that the little Lori was already drowsy, and Cheng Yun was still pinching its little jio to play.

What a jealousy!
