The five-and-a-half-year-old baby doctor comes to the city to cure those who refuse to listen.

Lin Jianguo held the blood-red Ganoderma lucidum in his hands, which were trembling.

He looked at Chu Chen, then at the rare treasure in his hand, his mind a little confused.

"Chen'er, stop fooling around."

Lin Jianguo squatted down and brought the Blood Ganoderma lucidum to Chu Chen's face.

"This is the real treasure, a life-saving treasure."

He pointed to the dirty and broken wooden box in Chu Chen's arms.

"That...that thing is taking up too much space to throw away, and it might even be infested with maggots."

Chu Chen hugged the box and shook his head.

He held the box up to Lin Jianguo, his eyes clear and untainted.

"I don't want that red mushroom."

"I want this one."

Why is this child so stubborn?

Lin Jianguo sighed; he had never seen such a stubborn child.

"Listen to your grandfather, this Blood Ganoderma lucidum was from your great-grandfather back then..."

"In my dream, my grandfather said that red mushrooms are beautiful poisons, and eating them will make you sleep in."

Chu Chen interrupted him, his little face serious.

"The baby in this box is the one who can wake up Mommy."

A beautiful poison? A sweet baby?

Lin Jianguo was left speechless, both amused and exasperated by this explanation.

Looking into Chu Chen's earnest eyes, and recalling the bizarre events that had occurred that day, the scales in his heart began to tip.

"You...you really want this?"

Chu Chen nodded vigorously.

"good!"

Lin Jianguo gritted his teeth, casually put the priceless Blood Ganoderma back into the wooden box, and didn't even glance at it again.

He took the tattered black box from Chu Chen's hand.

The box is quite heavy, much heavier than it looks.

The iron bars on top were rusted beyond recognition, and the wood was rotten, emitting a musty smell.

Lin Jianguo looked at it over and over again.

"It's locked, it's rusted, we can't open it."

He used his fingers to pry open the tiny keyhole, and rust flakes fell off in a flurry.

Chu Chen stretched out his little hand.

"I'll do it."

Lin Jianguo hesitated for a moment, but still handed the box to him.

Chu Chen held the box in his palm, his two little hands feeling around the edge of the box.

He found an inconspicuous mortise and tenon joint and gently pressed his little finger on it.

There was a soft "click".

The rusted iron bar sprang back with a snap.

The box lid is loose.

Lin Jianguo's eyes almost popped out of their sockets.

He tried for ages to open it but couldn't, and this kid... just pressed it once?

Before he could recover from the shock, Chu Chen had already opened the box.

An ancient scent, even more ancient than the smell of rust, carrying the unique coldness of metal and stone, emanated from the box.

There was no dazzling light or the fragrant aroma of medicine as I had imagined.

Inside the box, there was a piece of deerskin that had turned black.

Nine needles of varying lengths lay quietly on the deerskin.

These needles were completely black, as if they were made from the most ordinary cast iron, with a pitted and dull surface.

Even the tips of some of the needles had a bit of rust on them.

"That's...that's it?"

Lin Jianguo leaned closer, his head buzzing.

He thought it contained some kind of peerless elixir or some ancient treasure.

The result was nine broken iron needles that even a barefoot doctor would disdain.

He pointed to the blood-red lingzhi mushroom he had thrown aside, then to the iron needles in the box, his voice changing.

"Chen'er, are you willing to give up that Blood Spirit Mushroom, which could be traded for half a city, for these few pieces of scrap metal?"

"Grandpa, you made the wrong choice."

Chu Chen carefully extended his finger and gently touched the longest needle among them.

He didn't answer Lin Jianguo's question, but simply looked up at him calmly.

"The baby isn't the one that's red and big."

"What can save lives is the treasure."

Lin Jianguo was stunned.

Looking at Chu Chen's youthful face, it felt like a thunderbolt had exploded in his mind.

On the train, the intern doctor accidentally dropped two silver needles.

In the pharmacy, there were those few lines of nursery rhyme that pinpointed the root cause of the illness.

And just now, when military vehicles surrounded the gate, this child remained calm and composed.

Scene after scene flashed before his eyes.

He always believed that his daughter, Lin Xiutian, was a prodigy who had taught herself medicine in the countryside.

But now it seems that's not the case at all.

This child, from beginning to end, was not an ordinary five-year-old.

That so-called "white-bearded grandfather from my dreams," I'm afraid...

Lin Jianguo dared not think any further. He felt that his worldview was being shattered, piece by piece, by his five-year-old grandson.

He looked at Chu Chen, his gaze shifting from confusion to shock, and finally to deep awe.

"You...you're going to use this to save your mother?" he asked in a dry voice.

Chu Chen nodded.

He stretched out his two small hands and carefully took out the nine black needles.

He looked at his grandfather and spoke clearly, word by word.

"Grandpa, I also want three taels of gold, one mace of mercury, and the largest inkstone in your study."

Gold? Mercury? Inkstone?

What is all this?

Lin Jianguo completely gave up on thinking about it.

He now felt that even if Chu Chen said he wanted the moon in the sky, he would find a way to build a ladder to get it.

"good!"

Lin Jianguo nodded heavily, his face showing a resolute determination to go all out.

"Here you go! If you need anything else, just tell Grandpa!"

He turned around and strode out of the medicine storehouse.

"From today onwards, whatever you fancy from Jishetang or the Lin family, you can take it!"

"As long as you can save my daughter, you can tear down this century-old business!"

The old man's back view carried a tragic and resolute air of desperation.

In the medicine storehouse, only Chu Chen remained.

The dim light of the kerosene lamp cast a long shadow of his small figure.

He lowered his head, looking at the nine unremarkable black needles in his palm.

A familiar feeling of blood connection surged from my palm, along my arm, and into every part of my body.

This is not an iron needle at all.

This was his natal magic weapon, which he had forged for eighty-one days in his previous life as the God of Medicine using celestial iron and divine lightning from the nine heavens.

The Big Dipper.

Unexpectedly, the alchemy furnace exploded, shattering the soul. Even the set of divine needles was blown to the mortal realm, losing all its spiritual energy and becoming like ordinary iron.

He gently stroked the cold needle and probed it with his divine sense.

One can also sense that deep within the divine needle lies a faint trace of his own primordial divine power.

Chu Chen's lips finally curved into a smile that went unnoticed by anyone.

He put the nine magic needles back into the old black wooden box one by one, then picked up the box and walked out of the medicine storehouse.

Blood Ganoderma?

That is a treasure for mortals.

With this set of divine needles, he was able to re-establish the "Big Dipper Life-Sustaining Array," using heaven and earth as a furnace and the sun and moon as fire to reforge his mother's life essence.

That's true defiance of fate.

He carried the box and walked to the entrance of the medicine storehouse.

For the first time, the two elderly people, who were like statues, opened their eyes at the same time.

Their gazes were not on the box of blood spirit mushrooms left behind by Lin Jianguo, but fixed on the tattered black wooden box in Chu Chen's arms.

Their faces bore an incomprehensible, deep-seated fear.
