The white rose I picked up cried and said she liked me.

Although the proposal was successful, the couple is not in a hurry to arrange a wedding.

Xu Nian and Xu Xi have already committed to each other, but neither of them is in a hurry to prepare for the wedding.

For Xu Nian, his life has been missing too many years. Starting from scratch and quickly catching up with the 12 years of knowledge accumulated by others in elementary, middle and high school is not an easy task.

Moreover, he had long since missed the golden age of learning and was now middle-aged. As bodily functions decline with age, memory and comprehension slow down—a physiological hurdle that no one can overcome. Knowledge points that others can memorize in one go often require him to repeatedly recite and refine before they can even be barely etched into his mind.

If you lack natural talent, you can only make up for it with time.

Therefore, Xu Nian often studied late into the night by lamplight.

Fortunately, with Xu Xi, a former top student, tutoring him, his learning efficiency has improved considerably.

One evening, Xu Xi mysteriously took out a bottle of exquisitely packaged pills from her bag and handed it to Xu Nian.

Xu Nian looked at the densely packed foreign characters on the packaging box and scratched her head in confusion: "Xiao Xi, what's this?"

Xu Xi blinked and said mischievously, "The elixir of immortality."

"Come on," Xu Nian said with a helpless laugh.

If this had happened when he was less educated, he might have actually believed it.

But now that he's in school and has gained education and experience, such clumsy words naturally won't fool him.

Birth, aging, sickness, and death are the eternal laws of nature. This is not like the flesh of Tang Sanzang, so how could one possibly live forever?

It's probably some kind of imported health supplement.

Xu Xi chuckled. "Brother, don't underestimate it. This is the latest self-developed achievement of our group's biological laboratory, and it's not available on the market at all."

"While it cannot truly reverse aging or grant immortality, it can effectively activate human cell activity, repair bodily damage, delay aging, and extend lifespan."

"Most importantly, it can repair brain fatigue and reshape memory. After eating it, your memory can directly return to its peak state in your youth."

"Really? That's amazing?" Xu Nian raised an eyebrow, her eyes filled with disbelief.

"Of course." Xu Xi nodded without hesitation. "Grandpa Deng and Grandpa Liu have been taking this medicine continuously. You've seen their condition with your own eyes, and you can see how amazing the effect is by comparing them."

These words instantly caused Xu Nian's pupils to shrink and her heart to tremble.

He felt very strange when he visited his parents at the nursing home some time ago.

Grandpa Deng and Grandpa Liu are both nearly 100 years old, yet they are still full of energy, able to run and jump, have a good appetite, and can even easily learn to play chess on a smartphone, which is quite different from most other elderly people of the same age who can only lie in bed and rely on others for care.

At the time, he thought the two elderly people were just open-minded and in excellent physical condition. He never expected that it was the support of this self-developed drug.

At this moment, Xu Nian no longer dared to underestimate this small bottle of pills. He carefully unscrewed the cap, took out one pill, and slowly swallowed it with warm water.

The pill went down the throat with a sweet aftertaste, without any bitterness or medicinal taste.

In an instant, a gentle, clear warmth flowed down my throat and through my entire body, rushing straight to my mind.

My brain, which had been sore, tired, sluggish and dull, seemed to be injected with a powerful stimulant, and the fatigue and exhaustion brought on by days of staying up late to read were swept away.

The ancient poems and knowledge points that I couldn't remember no matter how hard I tried to memorize them were now clearly imprinted in my mind, word by word and sentence by sentence.

Even the weariness in her eyes disappeared, her gaze became clear and bright, and she felt refreshed.

"My God, this thing is amazing!"

Xu Nian was completely amazed and couldn't help but marvel, truly experiencing the charm of cutting-edge technology.

He had never imagined that such a miraculous substance, comparable to a low-budget version of Tang Sanzang's flesh, actually existed in the real world; it was truly astonishing.

He was still not satisfied and wanted to take another pill, but Xu Xi stopped him as soon as he touched the bottle.

"Brother, you can't take too many of these." Xu Xi took the pill from his hand, put it back in the medicine bottle, and said with heartache, "This medicine has a very high absorption threshold, and the human body has a limited capacity. You can only take one pill a week."

"Taking multiple medications in a short period of time will prevent the body from absorbing their effects, which is a waste."

"Are there any side effects?"

Xu Xi thought for a moment and said, "No, that's not the case."

Xu Nian chuckled, scratched her head, and whispered, "If there are no side effects, then I'll eat it like candy. It tastes pretty good."

Xu Xi rolled her eyes at him, then said, half-laughing and half-crying, "Brother, do you know how much this bottle of 'candy' costs?"

"How much?"

Xu Xi slowly extended one finger.

"One thousand? Ten thousand?" Xu Nian asked subconsciously.

He has browsed a lot of information on a regular basis and found that most of the popular health products on the market are more hype than effectiveness, with low cost and inflated prices.

In his view, such a top-notch imported self-developed drug, priced at tens of thousands of yuan per pill, is already an astronomical price.

Xu Xi gently shook her head and said calmly, "One hundred million US dollars."

"How much...how much more?" Xu Nian gasped, almost dropping the medicine bottle in her hand.

"Of course, what did you think?" Xu Xi tilted her head and pouted. "Mr. Zoro approached me before, offering 1 million US dollars for a bottle, but I didn't sell it to him."

"Actually, the biggest problem with this medicine isn't the price, but the scarcity of the raw materials. The lab's production capacity is limited; they can only produce one bottle a month. So, brother, you should use it sparingly."

Xu Nian felt a tightness in her throat, a wave of dizziness washed over her, and her heart was filled with regret and heartache.

The single pill he just swallowed so easily was worth far more than the life savings of countless people.

If he had known how precious it was, he would have loved to grind the pills into powder and mix them with water little by little before taking them. Swallowing them directly would have been such a waste.

However, after taking this drug, his learning efficiency did indeed improve dramatically.

The mathematical and scientific problems that he used to struggle with without any clue, the humanities knowledge points that he could not remember after repeated memorization, and the obscure professional theories have all become simple and clear to him. He can master them as easily as taking candy from a baby, and his learning efficiency has doubled.

Xu Xi seems to have become very busy lately, often leaving early and returning late, as if she is planning something big.
