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

Lin Jianguo led Chu Chen out of the medicine storehouse, his steps still a little unsteady.

He glanced back at the heavy stone door, then at the box of neglected blood spirit mushrooms in his arms, and then at the dirty and broken black wooden box in his grandson's hand. His mind was still in turmoil.

The two old men guarding the door remained like two stone sculptures from beginning to end.

Just as Chu Chen stepped out the door with the box in his arms, both of their eyelids twitched at the same time.

Their gazes were not fixed on the priceless Blood Spirit Mushroom, but rather on the broken box, their faces bearing an indescribable solemnity.

Lin Jianguo didn't notice any of this; all he wanted to do now was to quickly find the gold and mercury that his grandson had told him to do.

Just as he was about to speak, a series of hurried footsteps suddenly came from outside the moon gate in the backyard.

A middle-aged man in a white coat, with slightly disheveled hair, ran in, panting and covered in sweat.

"Old Lin! Old Lin! I heard something happened, the army has arrived, are you alright?"

The visitor was none other than Dr. Liu, a renowned surgeon from Peking Union Medical College Hospital in Beijing.

He spotted Lin Jianguo in the yard at a glance, and just as he was about to go over, his gaze was instantly drawn to the child next to Lin Jianguo.

His steps stopped.

Lin Jianguo is a highly respected figure in Beijing's medical community, but Dr. Liu acted as if she didn't see him at all.

He bypassed Lin Jianguo, walked a few steps to Chu Chen, his expression excited and his breathing rapid.

In his hands, he held a thread-bound ancient medical book with yellowed pages.

"Little...Little Master."

Dr. Liu's voice trembled slightly.

He held the ancient medical book above his head with both hands, his posture extremely low, even bending slightly at the waist.

"On the train, sir, was the intern you had perform the legendary 'Nine Needles for Resurrection' that had been lost for so long?"

Lin Jianguo almost choked on his breath again after he had just caught his breath.

Nine Needles for Rejuvenation?

Isn't that a kind of acupuncture technique that's only mentioned once or twice in ancient books and unofficial histories, almost like a myth?

How is that possible!

The maids and servants around them were also dumbfounded.

Those servants who had worked at Jishetang for a long time knew exactly who this Dr. Liu was.

That's a national champion who can stand shoulder to shoulder with Grandpa Lin, and even the city's top leaders treat him with utmost respect.

Now, he's actually addressing a five-year-old toddler as "sir"?

Chu Chen glanced at the ancient book, then looked up at Doctor Liu.

"Where did you get this book from?"

Dr. Liu was flattered and quickly replied.

"It's a fragmented copy passed down in my family. I'm dull-witted, and after studying it for half my life, I've only grasped a little bit of its essence. There are many contradictions in it, and I just can't understand it."

Chu Chen extended a little finger and tapped it on the ancient book.

"It's not that it's contradictory, it's that you're stupid."

Dr. Liu was taken aback by the scolding, but instead of getting angry, he became even more respectful, like a primary school student listening attentively in class.

Chu Chen shook his head and continued.

"This book is wrong from the very beginning."

"First, the Qi flows through the Du meridian, drawing fire back to its source. You think this is restoring Yang? It's actually hastening death. Treating a patient with acute heart failure is like pouring oil on a pile of nearly extinguished charcoal. It looks brighter, but it actually burns even faster."

"Secondly, you're trying to prolong life by circulating blood through the Ren meridian and strengthening the body's foundation? That's like pushing someone towards death. The patient's vital energy has already dissipated, and you're forcing their blood to bulge—isn't that just asking for their blood vessels to burst?"

"The stupidest thing was this third injection."

Chu Chen paused and looked at Dr. Liu.

"Needle Baihui to invigorate the spirit. The patient was already hanging on by a thread, no different from someone who was about to starve to death. Your needle is like pulling this starving ghost out of bed and forcing him to run 10,000 meters."

"Do you think he might just die right there and then?"

Every word Chu Chen uttered was like a heavy hammer blow to Dr. Liu's heart.

The obstacles he had struggled with all his life, those seemingly contradictory scriptures, were now being explained clearly and plainly by a five-year-old child in the simplest and most straightforward language.

His face went from flushed red to deathly pale, and then from deathly pale to a flushed red like someone who had just attained enlightenment.

"I...I understand!"

Dr. Liu was jolted, as if struck by lightning.

He loosened his grip, and the ancient medical book he treasured fell to the ground with a "thud".

He didn't even glance at it.

With a "thump," this renowned medical expert from the capital knelt down before Chu Chen in front of everyone.

He prostrated himself, his forehead striking the cold bluestone slab heavily.

"I, Liu Zhen, have been dull-witted for half my life, but today I have heard of the Great Way! I beg you, Master, to have mercy and accept me as your disciple!"

Lin Jianguo stood to the side, swaying slightly, almost falling to the ground.

He looked at Dr. Liu kneeling before his grandson, and at the servants who were too frightened to breathe, and his mind went blank.

He slowly turned his head and looked at Chu Chen.

That small figure remained calm.

It's as if making a national athlete kneel in public is just a trivial matter.

A surge of indescribable joy and pride welled up in Lin Jianguo's heart, and his eyes welled up with tears.

My Lin family's prodigy!

Do not!

This is not a child of exceptional talent, but a true dragon! A true dragon lurking in a fishing village, poised to stir up the world when the winds of change blow!

He remembered Lin Fu, whom he had kicked away and who had been taken away by the officials.

Lin Fu, Lin Fu, open your dog eyes and take a look!

This is the little beast you've been talking about! This is the scourge you've been calling a menace!

What can you use to fight him?

Chu Chen ignored Dr. Liu kneeling on the ground, and also didn't look at his grandfather who was so excited he was about to pass out.

He simply walked over and tugged at Lin Jianguo's sleeve.

Grandpa, what are you standing there for?

Chu Chen tilted his head back, looking completely at ease.

"Three taels of gold."

"Mercury, one mace."

"And that biggest inkstone in your study, hurry up, I'm waiting to use it."

Lin Jianguo snapped out of his daze and was pulled back from his overwhelming emotions.

"Yes! Yes! The important thing is to get down to business!"

He no longer cared about Dr. Liu or the Nine Needles for Rejuvenation.

Now, a grandson's words carry more weight than an imperial edict.

"Come on! Grandpa will take you to get it right away!"

He grabbed Chu Chen and turned to leave.

Dr. Liu, who was kneeling on the ground, became anxious and disregarded etiquette. He crawled two steps on his knees and hugged Chu Chen's calf.

"Sir! You haven't agreed to take me in yet!"

Chu Chen glanced down at him and frowned.

"Quarrel."

He thought for a moment, then pointed to the ancient book on the ground that Dr. Liu had thrown away himself.

"Burn that thing. Keeping it will only harm people."

After saying that, he ignored him and pulled Lin Jianguo toward the study.

Dr. Liu stood frozen, clutching Chu Chen's leg.

It burned?

I've spent half my life studying this family heirloom, and you're saying it was burned?

He watched Chu Chen and Lin Jianguo's departing figures, then looked at the ancient book on the ground, a complex expression of both crying and laughing on his face.

He slapped his thigh sharply.

"Burn! It must be burned!"

"If the gentleman says it's garbage, then it's garbage!"

He picked up the ancient book, carefully brushed off the dust, and then tucked it into his pocket with great care.

Then, he stood up and, without leaving, stood respectfully at the back gate, like a most loyal doorman.

He made up his mind: if the man didn't agree today, he wouldn't leave.
