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

Lin Jianguo told Chu Chen to learn medicine from Wang Dequan, but no one dared to actually treat this little rascal as an apprentice.

Every day, Wang Dequan would respectfully invite Chu Chen to the pharmacy, have him sit on a small stool behind the counter, give him a dish of candied fruit, a plate of snacks, and a few pieces of cheap medicinal herbs to play with as building blocks.

"Young master, this is astragalus, it's good for replenishing qi."

"Young master, this is angelica root, it's good for replenishing blood."

Wang Dequan carefully introduced the herbs to Chu Chen, who was holding two pieces of medicinal herbs and fiddling with them without looking up.

Of course he knew what it was.

He even knew that this piece of astragalus came from the north, was only three years old, and had a mild medicinal effect, far inferior to the few hundred-year-old wild ginseng roots in the warehouse.

He came here not to learn about medicine.

Every day, the pharmacy is bustling with people, and the staff are busy preparing and processing medicinal herbs. The rich aroma of the herbs is their best source of nourishment.

That morning, Chu Chen was building a small house with a few pieces of Poria cocos when a commotion suddenly broke out outside the medicine hall.

"Make way! Make way, everyone!"

Lin Fu jogged in, personally leading two people, and rushed in with great fanfare.

Behind him followed a well-dressed but sallow-faced middle-aged man, supported by a bodyguard. The man would pant after taking a few steps and looked like he was about to collapse at any moment.

"Grandpa! Where's Grandpa?" Lin Fu shouted at the top of his lungs, his manner so dramatic that anyone who didn't know better would think the sky had fallen.

Lin Jianguo was resting with his eyes closed in the inner hall when he was disturbed by the shout, and he frowned and was helped out by a maid.

"What's the panic! Can't you see there's a patient here?"

When Lin Fujia saw Lin Jianguo, his face immediately filled with anxiety and concern.

"Sir! Please take a look at Boss Huang! He's been a regular customer of ours for years. This morning he suddenly couldn't breathe, and after visiting several hospitals, they couldn't figure out what was wrong. That's why he came straight to Jishetang!"

As he spoke, he helped the fat man surnamed Huang to a chair.

Lin Jianguo glanced at the patient's face and his heart skipped a beat.

He walked up to Boss Huang, extended three fingers, and placed them on his wrist.

After a while, Lin Jianguo loosened his grip, his brows furrowed into a knot.

"The pulse is deep and slow, the breath is weak, and the tongue coating is white and greasy..." he muttered to himself, and then asked a few more questions.

"Boss Huang, have you eaten anything unclean these past few days?"

Mr. Huang shook his head listlessly.

"Have you caught a cold?"

Boss Huang shook his head again.

Lin Jianguo asked seven or eight questions in a row, and Boss Huang denied them all.

That's strange.

Without external pathogens or internal injuries, where did this illness come from?

Lin Jianguo sat at the table, stroking his beard, hesitating to put pen to paper.

He's old, and last night he got really worked up, which upset him. Right now, his mind is a complete mess, and he can't seem to grasp the root of the problem.

Lin Fu stood to the side, watching the fine sweat beading on Lin Jianguo's forehead, a glint of triumphant gleam in his eyes.

He deliberately brought this difficult case here today.

Several well-known Western hospitals in Beijing were helpless to treat Boss Huang's illness, and he refused to believe that Lin Jianguo, with his old bones, could diagnose it.

If Lin Jianguo admits defeat in public, then Lin Fu will have something to say.

The old man is getting old and can't go on. Jishetang will have to rely on him to keep it going in the future.

"Grandpa, don't rush, think it over slowly." Lin Fu offered a cup of hot tea with feigned concern. "Boss Huang's health is of utmost importance, so this prescription needs to be carefully considered."

His words, ostensibly out of concern, were actually a urging and pressure tactic.

Lin Jianguo was upset and waved his hand, refusing to take the cup of tea.

The lobby was eerily quiet; all the staff and patients were staring at Lin Jianguo, creating a tense atmosphere.

In the corner, two new young men were whispering to each other.

"Oh no, it seems even the old man can't tell."

"Barbie Q is in trouble now. Boss Huang is not someone to be trifled with."

Just then, a childish, slightly naive voice rang out in the quiet lobby.

"The sun sets behind the mountains, and the metal element descends. A persistent cough at night, and even the water becomes oilless."

The sound wasn't loud, but it reached everyone's ears clearly.

Everyone looked in the direction of the sound and saw the little guy behind the counter, intently building his little house with medicinal herbs, muttering to himself as if the song he had just sang was something he had made up on the spot to amuse himself.

Lin Fu's face darkened, and he was about to reprimand him.

"Shut up!"

Lin Jianguo suddenly slammed his hand on the table and stood up.

He stared intently at Chu Chen, repeatedly chanting those few lines of the ballad.

"The sun sets behind the mountains, the metal element descends... I cough incessantly at night..."

Metal element governs the lungs.

The sun sets at the hour of You (5-7 PM).

The hour of You (5-7 PM) is when the Kidney Meridian is at its peak.

A cough occurring at the hour of You (5-7 PM) indicates symptoms in the lungs, but the root cause lies in the kidneys!

It is due to a deficiency of kidney water, which is unable to nourish the heart fire, causing the deficiency fire to rise and scorch the lung metal!

The meridian flow, the alternation of day and night—the root of this illness is hidden too deeply!

"I understand!" A startling light suddenly burst forth in Lin Jianguo's cloudy eyes.

All his confusion and doubts were completely dispelled at this moment by these seemingly casual nursery rhymes!

He pushed aside the teacup in front of him, grabbed a pen, and began to write on the paper with flowing, elegant strokes.

"Six qian of raw Rehmannia root nourishes Yin and tonifies the kidneys; five qian of Ophiopogon japonicus clears the heart and moistens the lungs; add three qian of Schisandra chinensis to astringe lung Qi..."

He wrote with lightning speed, completing the work in one go.

After writing it down, he slapped the prescription onto Lin Fu's face.

"Prepare the medicine according to the prescription! Boil three bowls of water down to one bowl, and give it to Boss Huang immediately! He'll be able to walk again in half an hour!"

Lin Fu was bewildered by his sudden change.

He held the prescription, looking at the medicinal herbs on it, with a mixture of belief and doubt.

This prescription seems ordinary, is it really that miraculous?

Boss Huang also looked doubtful.

But right now, we have no choice but to try anything, even if it seems hopeless.

The shop assistant grabbed the medicine and quickly took it to the backyard to decoct it.

Half an hour later, a bowl of dark, murky medicine was served.

Boss Huang pinched his nose and gulped it down in one go.

About the time it takes for an incense stick to burn has passed.

A miracle happened.

A wisp of color slowly returned to Boss Huang's originally sallow face.

He exhaled a long, comfortable breath.

As he exhaled, he felt as if the heavy stone that had been pressing on his chest had been instantly removed.

"I...I can breathe again!" Boss Huang stood up in surprise and walked around twice, feeling that his steps were much lighter.

"Amazing! Dr. Lin! You are truly a reincarnation of Hua Tuo!" Boss Huang excitedly grabbed Lin Jianguo's hand, almost kneeling down before him.

The surrounding staff and patients erupted in thunderous cheers.

"As expected of the old master of Jishetang!"

"One dose of medicine and it worked! He's a miracle doctor!"

Lin Fu stood in the crowd, his expression even more unpleasant than if he had swallowed a fly.

He stared intently at Chu Chen, who was still playing with the medicinal herbs, his mind in turmoil.

It's that little brat again!

How could he possibly know these things!

Amidst the praise of the crowd, Lin Jianguo gradually calmed down.

He pushed through the crowd, walked up to Chu Chen, squatted down, and his voice trembled slightly, a tremor he himself didn't even realize.

"Chen'er, who taught you that nursery rhyme just now?"

All eyes instantly turned to Chu Chen again.

Chu Chen raised his head, blinked his big, dark eyes, and looked completely bewildered.

"Folk songs?"

He seemed to think hard before he suddenly realized.

"Oh, that one."

He pointed to the little house he had built with poria cocos, looking completely innocent.

"This is something Mom always says to herself when she's sick."

"I don't know what it means, I just thought it sounded nice, so I remembered it."

Once again, without batting an eye, he attributed all the credit to his mother, who was no longer alive.

This reason is irrefutable.

Upon hearing this, Lin Jianguo's eyes welled up with tears, and he reached out to hug Chu Chen tightly.

"My poor, unfortunate daughter...it turns out she actually inherited my true skills...It's my fault...I'm the one who wronged her..."

Looking at the grandfather and grandson embracing each other and listening to the praise for Lin Jianguo around him, Lin Fu felt as if a mouthful of blood was stuck in his chest.

He wanted to embarrass the old man, but instead of succeeding, he boosted the old man's reputation even further.

He looked at Chu Chen, who was nestled in Lin Jianguo's arms with an "innocent" expression, and felt a surge of hatred welling up inside him.

I would really thank you

You little bastard, you just wait!

I simply don't believe that your mother, a country woman, could possibly understand anything about the Meridian Flow Theory!

He quietly retreated to the back of the crowd, and speaking to a trusted confidant, he lowered his voice and gritted his teeth as he gave the order.

"Go! Prepare the car!"

"I want to go to that fishing village in the East China Sea myself!"

"I'm going to investigate that woman Lin Xiu thoroughly, down to the last detail!"
