A young boy from the 1970s, separated from his family, fled famine and led his younger brother into

"To...do business?"

Looking at her daughter's serious little face, Zhou Yayun felt like her brain wasn't quite working properly.

In her mind, "doing business" was synonymous with "speculation and profiteering." That was something that could get you arrested and criticized!

"Nianci, don't do anything reckless!" She nervously grabbed Lu Nianci's hand and whispered, "This is no joke! What if we get labeled as 'capitalist remnants' and cut off?"

"Mom, don't worry." Lu Nianci looked at her mother's worried face and comforted her with a smile, "The business I'm talking about is not the kind of speculation, but creating wealth with our own hands and wisdom."

"This is called getting rich through hard work! It's honorable!"

She redefined the meaning of "business" in a language that people of this era cannot fully understand.

Lu Zhenguo looked at his daughter in silence.

While he didn't entirely approve of her getting involved in money-related matters at such a young age, he was even more curious. Just how many other extraordinary ideas were hidden in the mind of his "prodigy" daughter?

"What kind of business do you want to do?" he asked in a deep voice.

Lu Nianci smiled mysteriously, keeping everyone in suspense: "It's a secret for now. But I guarantee it will be a great thing for the country and its people!"

Looking into his daughter's confident and cunning eyes, Lu Zhenguo finally chose to compromise.

He sighed and said to Zhou Yayun, "Forget it, you keep the money for her. Let her do whatever she wants."

"As long as it doesn't break the law or violate principles, we'll just stand by and watch."

He had a premonition that his daughter might actually be able to accomplish something truly unexpected, something that would surprise him and everyone else.

……

Three days later, it was time for Gu Jiusi to return to the capital.

The military region sent a special car, and Lu Zhenguo and Lu Nianci personally went to see him off.

There was no grand procession to see them off, nor any celebratory farewell ceremony with gongs and drums.

Everything was done discreetly and quietly.

This was both Gu Jiusi's own request and an instruction from his superiors.

After all, he was carrying out an extremely important confidential mission when he returned this time.

Just before getting into the car, Gu Jiusi pulled Lu Nianci aside.

He took out a large package wrapped tightly in oilcloth and a seemingly ordinary brass key from his worn-out canvas bag.

"Child, your teacher doesn't have anything nice to give you."

He stuffed the heavy package and keys into Lu Nianci's hands, his bright old eyes filled with reluctance and affection.

"In this package are some notes and manuscripts that I've compiled over the years, some on physics, some on medicine that you might be interested in, and some... things left behind by my good-for-nothing apprentice, Zhou Wenxuan."

"You are exceptionally intelligent and quick to understand. These things will be more useful to you than to an old man like me."

Holding the heavy package, Lu Nianci felt as if she were holding not a pile of paper, but the old man's life's work and legacy.

Her eyes instantly welled up with tears.

"teacher……"

"Don't cry." Gu Jiusi smiled and patted her head. "We're not facing a life-or-death separation."

"We'll meet again in the capital soon."

He picked up the brass key again and solemnly handed it to her.

"Keep this key safe."

"This is the key to my place in Beijing. The address is engraved on the key handle. It's a very safe place; nobody knows about it."

"In the future, if you encounter any trouble when you arrive in the capital, or if you don't want to live in the Gu family anymore, you can go there anytime."

"Remember, that's your home too."

There seemed to be some deeper meaning hidden in Gu Jiusi's words.

Lu Nianci keenly sensed that her teacher seemed to have foreseen that her future path in the capital would not be smooth sailing.

She didn't ask any further questions.

She simply clutched the key, still warm from the teacher's touch, tightly in her hand and nodded emphatically.

"Teacher, don't worry."

"I will definitely go to the capital to find you."

"I also want to hear you explain quantum mechanics and the Big Bang!"

"Good, good, good!" Gu Jiusi laughed heartily.

He took one last deep look at his most prized disciple, then resolutely turned around and boarded the car that would take him back to glory and his dreams.

The car slowly started moving and eventually disappeared at the end of the road.

Lu Nianci stood there, motionless for a long time.

She knew that her teacher's departure meant that she had lost one of the most important mentors and protectors in this military compound.

She will have to walk the rest of the road alone.

Back home, Lu Nianci locked herself in her room and carefully opened the heavy oilcloth package.

Inside were thick stacks of manuscripts.

The paper has long since yellowed, but the handwriting remains strong and powerful.

She had familiar formulas for deducing relativity and quantum physics.

There were design drafts with various intricate mechanical drawings that she couldn't understand.

There was also a surgical notebook that made her gasp for breath!

The cover of the notebook was worn out, but the contents inside were perfectly preserved.

The book uses an extremely concise style to record in detail various surgical procedures that were considered "fantasies" in the 1970s!

From the most basic debridement and suturing to complex limb replantation, and even... the theoretical concept of coronary artery bypass surgery!

The advanced nature of his ideas and the boldness of his thinking left even Lu Nianci, a top surgeon in his previous life, in awe!

She was certain that this was definitely not the work of Teacher Gu Jiusi!

Although physics and medicine have some commonalities, they are worlds apart.

This must be... Zhou Wenxuan's belongings!

That genius agent who, like her brother Lu Xingzhou, belonged to the "Sharp Sword" special operations team, but had already sacrificed himself!

Lu Nianci's heart began to pound uncontrollably!

She finally understood why Teacher Gu Jiusi had said that Zhou Wenxuan was his "good-for-nothing" disciple.

Because this apprentice's talent is not in physics at all!

He was a born surgeon! A medical genius whose talents were wasted on a career as a secret agent!

The value of the notebook he left behind is simply immeasurable!

It is more than just a surgical notebook.

It is also a key! A key that can unlock a new era of modern surgery in China...

Lu Nianci stretched out her slightly trembling hand and gently stroked the familiar, powerful handwriting.

A strong, long-lost impulse surged forth from the deepest part of her heart!

She wanted to pick up a scalpel!

She wants to return to the battlefield she knows and loves most!

She wanted to use the knowledge in this notebook to save more lives!

but……

She looked down at her small, delicate hands, which were only the size of a five-year-old child's.

A deep sense of powerlessness gripped her.

No.

Not yet.

She is still too young and too weak.

She doesn't yet have the ability to protect this earth-shattering treasure.

She has to wait.

Wait until she grows up.

She passed the exam and was admitted to the capital.

When she has enough say and power!

Lu Nianci took a deep breath, forcibly suppressing the surging emotions in her heart.

She carefully rewrapped the precious surgical notes and other manuscripts left by Professor Gu Jiusi, and then hid them in the most secret corner under the bed.

After doing all this, she felt her wildly beating heart calm down a little.

She walked to the window and opened it.

The early winter wind, carrying a hint of desolation, blew against my face.

In the courtyard, a few withered yellow leaves twirled in the air before drifting down.

Looking at the empty courtyard, Lu Nianci felt a sense of emptiness in her heart.

The teacher has left.

My younger brother has also passed away.

This home, which once made her feel incredibly warm and safe, suddenly seemed much quieter.

Just then, a chattering sound, accompanied by the laughter of several women, came from not far downstairs.

"Hey, have you heard? That new girl at Political Commissar Lu's house is really something!"

"It's not just incredible! It's practically all-powerful!"

"That's right! We just welcomed the old leader of the Gu family a few days ago, and now, in just a few days, we've brought that old man Gu, who swept the library for ten years, back to the capital to become a high-ranking official!"

"I heard that when the Gu family left, they sent the Lu family a whole truckload of gifts! Color TVs! Refrigerators! We've never even seen those before!"

That sour, jealous voice pierced Lu Nianci's ears like needles.
