"Brother Lin, remember to go to Yanjing International tonight."

Jia Mimi watched Lin Hai's distant figure and hurriedly called out to remind him.

"What exactly does Beautiful Principal Ning want from me?"

As Lin Hai raced towards the university, he already had a suspicion.

"The reason they're looking for me is most likely because of the prescription from last time."

A slight smile curved his lips. He had predicted that the other party wouldn't use the prescription rashly but would seek verification instead.

He just didn't know if this time they were seeking his advice or expressing some admiration and gratitude.

Lin Hai entered the university with a smile, and not far away, Bao Dazhong, upon seeing Lin Hai, immediately showed a keen smile.

Arriving at the door to the principal's office, Lin Hai slightly furrowed his brows.

With his current abilities, he could clearly hear at least four breaths from inside the room.

Which meant there were at least five people present in the office.

Moreover, judging by the rhythm of the breathing and heartbeats, there should be two elderly individuals.

Knock, knock, knock—

Lin Hai knocked on the office door.

"Come in." The voice of Beautiful Principal Ning came through.

Lin Hai opened the door and was momentarily stunned by the scene inside.

The five people in the room all looked over the moment he entered.

Among them, the gaze of the two elderly men with graying hair was particularly intense.

"Mr. Lin is here," Principal Ning said.

Lin Hai nodded, "Principal Ning, did you need something from me?"

As soon as he asked, an elderly man with a head full of white hair but with a stern face and an unshakable authority spoke calmly, "Is this the young Lin?"

Lin Hai was momentarily confused about the situation.

Professor Chen next to him looked proud and slightly admiring as he said, "Young Lin? This is Master Lin. For the past few days, I've been pondering Master Lin's taught techniques day and night. I've made great progress—last night, I encountered two thugs trying to snatch my wallet on my way home. Within minutes, I used Tai Chi Boxing so well they couldn't even recognize themselves."

After speaking, Professor Chen seemed to relish what had happened last night.

"Hmph, at your age, sparring with young thugs—be careful not to disgrace yourself," the elder scolded.

"You!" Professor Chen was so angry that he puffed his beard and glared.

The elder didn't look at Professor Chen but started to scrutinize Lin Hai with interest.

"Was it you who issued that prescription?" the elder asked, smiling.

Lin Hai nodded, "It was me. Hello, sir."

"Hmm, quite polite." The elder's mouth curved into a smile but suddenly turned cold, "However, lying is not a good thing."

"Lying?" Lin Hai was momentarily taken aback. How was he lying?

"Sir, I don't quite understand what you mean," Lin Hai asked.

The elder shook his head, "That prescription is not something someone your age could come up with."

"Did your mentor teach you?" the elder added.

Lin Hai was dumbfounded, then chuckled.

He had casually come up with a rough prescription, and it ended up being called a lie?

Moreover... a mentor? The Ghost Doctor had vanished after teaching him various medical skills.

"The herbs listed in your prescription are rather rare, and the technique is not bad. Why don't you invite your mentor over so we can all have a chat?" the elder asked, smiling.

Lin Hai was speechless and sighed, "That prescription was indeed my own idea."

"Young people are not honest. Are fame and fortune really that important?" The elder shook his head with disbelief.

"That prescription was indeed something I came up with, sir. On what basis do you assert that I'm lying?" Lin Hai retorted.

At this moment, a displeased and stern voice beside him spoke up, "Young man, Elder Tang is the leading figure in the Traditional Chinese Medicine Department at Yanjing University. Across the entire Yanjing, Elder Tang is a renowned figure in the medical field. If Elder Tang says it wasn't you, then it's certainly not you."

This person's tone was very unfriendly, and the look in his eyes bore a strong sense of rejection and hostility toward Lin Hai.

"Oh? May I know who you are, sir?"

Lin Hai squinted his eyes. The person's tone was harsh, with particularly sharp words, and his eyes carried a hint of confrontation.

"Who I am is none of your concern, young brat," the middle-aged man snorted coldly, seemingly disdainful of looking at Lin Hai again.

Lin Hai slightly furrowed his brows.

At this moment, Old Professor Tang spoke up, "Young man, where did you get this prescription?"

A cold smile appeared at the corner of Lin Hai's mouth, "Why should I tell you?"

"How dare you be so rude to Old Professor Tang!" the middle-aged man angrily rebuked Lin Hai.

Lin Hai didn't look at the middle-aged man but instead turned to Principal Ning and said directly, "Principal Ning, did you invite me here just to be interrogated?"

Principal Ning's elegant brow slightly furrowed, and she glanced at the middle-aged man beside her before explaining to Lin Hai, "Mr. Lin, please do not misunderstand. Because the matter of the prescription is quite significant, I wanted to investigate it thoroughly to ensure there's no mistake."

"Oh? No mistake in what way?" Lin Hai asked with a cold smile.

"To ensure this prescription can truly cure illnesses," Teacher Ning did not hide it and replied.

"Ha, to be frank, this prescription is actually for pest and rodent extermination. Take one packet, and you're guaranteed to kick the bucket. It's best your family's patient avoids this medicine, or else, Lin will take no responsibility if anything happens."

After speaking, Lin Hai turned and walked away.

"How dare you! Boy, you're too arrogant." The middle-aged man was enraged, pointing angrily at Lin Hai.

Lin Hai turned his head, his gaze cold and indifferent as he looked at the other person, saying plainly, "I won't stay here to listen to a dog bark."

"Who are you calling a dog?" The middle-aged man's face turned livid, and his fist clenched tightly.

"Whoever is barking is naturally the dog."

Lin Hai said this and couldn't be bothered to engage with these people any longer.

"Boy, I'll make you understand the consequences of a foul mouth!"

Suddenly, the middle-aged man attacked, a silver needle appearing between his fingers, aimed at Lin Hai's left neck artery from behind.

Feeling the gust from behind, Lin Hai's eyes turned icy.

"Acupuncture?"

"Restore life from death, heal flesh and bone!"

From Lin Hai's sleeve, two ancient-styled golden needles shot out, piercing with the speed of lightning.

The middle-aged man's lips curled with a cold smile. He didn't intend to kill Lin Hai, but merely wanted to teach him a lesson and embarrass him.

However, just as he was about to approach Lin Hai, he suddenly felt a stabbing pain in his wrist as if stung by a bee. Immediately after, he couldn't move an inch.

"This..."

"Golden Needle Sealing Acupoint!"

Old Professor Tang's eyes lit up, and even the elder beside him, who hadn't spoken yet, had a gleam in his eyes.

"Playing around with acupuncture in front of me?" Lin Hai's lips curled with a hint of mockery.

"These golden needles... young man, where did you get them?"

The elder who had been silent finally stood up quickly and spoke up.
