Why didn't you tell me earlier that my little sister is still waiting for me?

Lin Bufan glared at Ye Zhenzhen unhappily, then brought the topic back to where it had strayed again: "Zhenzhen, what is the biggest advantage of our product?"

"Beauty and youthful appearance!" Ye Zhenzhen answered without any hesitation.

"Huh~?!"

Lin Bufan didn't expect Ye Zhenzhen to give such a superficial answer. Is this a common problem among women?

Just look at the face!

Unexpectedly, even scientific researchers like Ye Zhenzhen are not immune to this!

But this is understandable. After all, it is inevitable that there will be some pressure when being with such a handsome guy like yourself!

Just when Lin Bufan was daydreaming, Ye Zhenzhen noticed that Lin Bufan looked unhappy and began to explain.

"I'm kidding. Of course I know it's anti-aging, reversing biological age. Beauty and youthfulness are only attractive to those who care about their appearance, but anti-aging is popular among men, women, young and old!

Especially those athletes and wealthy people, they certainly have no resistance to this!

Moreover, since it can resist aging and reverse biological age, it is very likely to extend lifespan. I have been researching this recently. If it really can extend lifespan, it would be crazy!"

Ok? !

Extend life?

Can we still play like this?

Mr. Lin, who didn't like to think about problems, just took a quick look at it at the time and threw it aside after knowing its efficacy. He didn't think deeply about it. Now after listening to Ye Zhenzhen's analysis, he feels that it does make sense.

But researching this kind of thing is not as quick as asking the system!

"Tongzi, Tongzi, Tongzi, Tongzi..."

Under Lin Bufan's deadly series of calls, the system issued an extremely impatient voice: "Don't you have a brain? You have to ask me everything? Can't you think for yourself?"

Obviously, the system already knew why Lin Bufan called it!

However, Lin Bufan did not feel the slightest bit ashamed of the system's accusations!

In his previous life, the two people Lin Bufan envied the most were the always complaining Crayon Shin-chan and Nobita who could only shout Doraemon. Now that he has a system comparable to Doraemon in this life, why should he still use his own brain?

"System dad, you're the best. Just tell me, okay?"

"It has a certain effect of prolonging life!"

Ok? !

what happened?

Why does it feel like the system suddenly shuddered?

Why do the words feel a little hasty?

Could it be? !

No way, no way!

Tongzi, I have always treated you as my brother, you can't have any improper thoughts about me!

Lin Bufan secretly decided in his heart that he must keep a distance from the system in the future!

After receiving a positive response from the system, Lin Bufan nodded in satisfaction, "Zhenzhen, I was right about you. I deliberately hid the life-extending effect just to test you. You didn't disappoint me. This formula does have a certain effect in extending life."

After receiving Lin Bufan's affirmative answer, Ye Zhenzhen almost jumped up in excitement, like a kindergarten kid who got a red flower: "I knew my reasoning was right!

If you want to reverse your physiological age, you must change the physiological state and physiological functions of cells, tissues, organs, and systems!

If you do all of this, then extending your lifespan will be a natural progression!"

Things were still perfect up to this point, but Ye Zhenzhen's next words almost made Lin Bufan go berserk: "Bufan, since you know you can extend your lifespan, you must have done some research, right? How long can it be extended?"

how long?

How would I know if the system didn’t tell me?

Also, if you have any questions, can't you ask them all at once?

Normally, Lin Bufan would have asked the system directly, but he just felt that something was wrong with the system, and at this moment Lin Bufan didn't want to talk to the system!

Just when Lin Bufan was struggling over whether to save face or maintain his moral integrity, the system actually spoke on its own initiative.

"Extend lifespan by about ten percent!"

shock! ! !

Three consecutive exclamation marks showed how shocked Lin Bufan was at that moment.

No, never, the system has never actively answered questions,

Something is wrong, something is extremely wrong, 12 points out of wrong!

Could it be that the system really wants to be gay?

That’s not right either!

The system didn’t seem to say it was a male!

Could it be that there is a girl operating the system in the background and talking to me?

Sure enough, no girl can resist the charm of this guy!

The more Lin Bufan fantasized, the more possible it seemed to him. He even imagined what the system girl looked like!

System: Fuck you! I don’t want to hear your perverted tone!

Lin Bufan smiled calmly and answered Ye Zhenzhen's question confidently, "It can extend your lifespan by about 10%!"

“10%？现在国内的平均寿命是76.3，增加10%也就是7.63，那国内的平均寿命就可以到达83.93！”

Just when Lin Bufan was about to praise Ye Zhenzhen for her math skills and show his boyfriend's emotional value, Ye Zhenzhen suddenly changed her mind!

"Wait, that's not right, it doesn't work like that!

This is just the average lifespan. If we calculate based on the maximum human lifespan of 120-150 years, then the increase in lifespan is 12-15 years!"

Ok? !

Is that much?

Then everyone can continue to attend classes for grades 12-15 happily, right?

that's nice!

Similarly, before Lin Bufan could even begin to praise her, Ye Zhenzhen spoke again: "Wait, that's not right!

Assuming that an average person starts using our products at the age of 20, and maintains healthy living habits, then when he is 80 years old, his biological age may be only in his 40s!

In this case, if there are no accidents, he is unlikely to die from various diseases, so his life span is likely to be extended even further. Maybe by then centenarians will be everywhere! "

One hundred years old?

Doesn’t that mean you can work until you are 80 years old?

This is so happy!

I envy them so much for being able to live a happy life of 996, while I, who am responsible for the future of the people, can only mess around!

Alas, this world is so unfair!

"Bufan, is my analysis correct?"

Looking at Ye Zhenzhen's eyes that were eager for knowledge, Lin Bufan knew that it was time for him to sacrifice again!

However, this sacrifice is different from the last time. This time, Lin Bufan is ready to discuss knowledge with the system girl!

"Sister Xiaotong, I have a question for you!"

"Get out of here, you pervert, I'm a real man!"

!!!

Damn it, what a rip-off!

The system sister turns into a big toe picker?

I didn't expect that this bastard system would actually use sting enforcement!

Lin Bufan, who was hit hard, collapsed directly on the chair like a salted fish who had lost his dream. At this moment, Lin Bufan just wanted to be quiet!

However, Zhenzhen didn't want Lin Bufan to be alone!

Seeing that Lin Bufan did not answer her question, Ye Zhenzhen stood up and walked to Lin Bufan and began to ask further questions!

"Bufan, please say something. What's going on?"

"How many years of life can be extended theoretically?"

"Can most people actually live to be 100 years old?"

......
