Chapter 821: Ten Thousand Credits?

"Not selling?" Zhang Xuan's face turned ashen when he heard the expected reply.

If it weren't for this guy, Wei Changfeng wouldn't have died!

After all that talk, he still refused to sell?

Indeed, a shameless master teacher was more terrifying than even the sacred beasts of Cloudmist Ridge!

"Precisely!" Vice Dean You waved his hand. "I don't have a habit of selling unripe goods. You may leave!"

Knowing that Wei Ruyan's life would be in peril without the Ten-leaf Flower, Zhang Xuan suppressed the urge to explode. "So, you mean you won't sell it if it's unripe, but if the Ten-leaf Flower matures, you will sell it?"

"Exactly!" Vice Dean You nodded. "How can I sell an unripe medicinal herb? You should understand the reasoning; I'm not intentionally making things difficult for you!"

"Alright then. Since you won't sell it unripe… I'll just make it ripen now!"

Casting a cold glance at the Vice Dean, Zhang Xuan turned and walked to the Ten-leaf Flower in the medicinal garden. He pointed a finger, and a few drops of Earth Vein Spiritual Liquid seeped in, followed by the infusion of Heaven's Path zhenqi.

While nourishing it purely with Earth Vein Spiritual Liquid could also make the Ten-leaf Flower ripen quickly, it would take at least a day. However, with the assistance of Heaven's Path zhenqi, the speed would increase significantly.

True to his words, as the zhenqi and spiritual liquid entered, the Ten-leaf Flower visibly grew. Within ten minutes, all ten flower buds fully bloomed, emitting an astonishing fragrance.

"This..."

Sun Yuan's eyes widened.

The Ten-leaf Flower was a sacred medicine that normally took ten years to ripen. Yet, the young man had done it in just ten minutes… How was that possible?

"It's matured, Vice Dean You. Can you sell it now?"

Zhang Xuan stood up.

Vice Dean You's face was ashen.

He said to exchange it for a Cloudmist Flower, and the person brought one. He said it wasn't alive, and the person revived it. He said the herb was unripe, and the person ripened it on the spot… This guy wasn't here to buy medicine; he was deliberately trying to humiliate him, wasn't he?

"What? The Ten-leaf Flower has matured, and Vice Dean You still doesn't want to sell it?" Seeing his expression, Zhang Xuan looked at him.

"Hmph! This Ten-leaf Flower was cultivated by my own hands. If I say I won't sell it, are you going to try to seize it by force?" Vice Dean You raised an eyebrow.

"Seizing something by force from a Vice Dean? Of course, I wouldn't dare!" Zhang Xuan shook his head, his gaze sharp as he looked back at him. "I'll ask you one last time: are you certain you won't sell it to me?"

"Precisely. My Ten-leaf Flower, even if it rots in the ground, will not be sold to someone like you, who disrespects elders and disregards rules!" Vice Dean You snorted.

"Very well!"

Without another word, Zhang Xuan turned and left, quickly disappearing from the courtyard.

"He left?"

Sun Yuan had expected the young man to do something outrageous, but he simply left, which surprised him. After a moment, he couldn't help but look at the Vice Dean. "Teacher, it's just a Ten-leaf Flower. If he wants to buy it, why not just sell it to him? Why make things so difficult…"

"Impudent! What, your wings have grown strong, and you want to lecture your teacher now?" Vice Dean You raised an eyebrow.

"This student wouldn't dare!" Sun Yuan clasped his fists. "I've just heard a lot about this fellow; he's said to be quite unconventional. I'm afraid… that thoroughly offending him might bring trouble!"

"Nonsense! I, You Xu, a dignified Saint realm expert and Vice Dean of the Physician School, what great storms haven't I weathered? Am I to be afraid of a mere student?" Vice Dean You scoffed coldly.

"It's just that…" Sun Yuan was full of worry.

There must be a reason why this person commanded such respect from Principal Mo Gaoyuan, Principal Mi, Principal Zhao, and Principal Wei Ranxue. If his teacher were to offend him rashly, would it in turn offend these principals, or even the Master Teacher Pavilion's head?

"There's no 'just that'. Here's what you'll do… Follow him and see. If that brat speaks ill of me in front of Principal Mi or the others, or spreads any false information, arrest him immediately and charge him with slandering a high-level master teacher!"

Vice Dean You snorted coldly.

"This…" Sun Yuan hesitated.

"Hurry up and go! It's a grave offense for a low-level master teacher to speak presumptuously about a high-level one! This fellow's rank is below mine. If he dares to speak carelessly in front of others, he's just asking for death!" Vice Dean You waved his hand.

"Yes!" Seeing his teacher's resolve, Sun Yuan had no choice but to nod and retreat from the courtyard.

It was indeed a violation for a low-level master teacher to speak presumptuously about a high-level one without concrete evidence. Zhang Xuan was only a four-star, while his teacher was at the peak of six-star, a difference of two ranks. If Zhang Xuan truly dared to speak ill, he could indeed be arrested on the spot.

Leaving the courtyard, Sun Yuan looked around and saw Master Zhang, who had just exited, not far away. He quietly followed.

Although he didn't quite agree with his teacher's actions, a teacher's command was not to be defied, so he strictly adhered to it.

"Is he going to see Principal Mi first, or Principal Zhao?"

Following from a distance, he speculated.

He had heard a lot about this Zhang Xuan; Principal Mi, Principal Zhao, and Principal Wei all treated him as a distinguished guest. If he were truly seeking trouble, he would surely approach one of them.

However, even if these three held esteemed positions, they weren't from the same academy as his teacher. At most, they would act as mediators; they shouldn't be able to do anything to his teacher.

"I think there's a higher chance he'll go to Principal Zhao. The Blacksmith School is ranked second, and they value him more…"

He muttered to himself, wondering who the young man would complain to, when he saw the youth ahead turn and walk straight into the Physician Tower.

"Hmm? What's he doing at the Physician Tower?"

His eyes blinked.

According to his thoughts, shouldn't this young man be appealing to the principals or causing trouble for his teacher? Why had he gone to the Physician Tower instead?

"I'll go take a look!"

He hurried after him.

The Physician Tower was bustling with people. Zhang Xuan disappeared into the crowd, and Sun Yuan searched for a long time but couldn't find him. Unable to wait any longer, he approached the front desk.

A girl stood behind the counter. Seeing him approach, she quickly clasped her fists and greeted, "Teacher Sun…"

It was the same girl who had guided Zhang Xuan to the separate courtyard that day.

"Yes, have you seen the new student named Zhang Xuan?" Sun Yuan asked.

"Zhang Xuan?" The girl was startled.

"The one you took to see Vice Dean You that day!" Sun Yuan frowned.

"He… he is Zhang Xuan?" The girl covered her mouth, her eyes wide with excitement, as if she had just seen an idol.

To be honest, within a few days, there were few people on campus, whether teachers or new students, who didn't know the name "Zhang Xuan."

"Ahem! Have you seen him?" Seeing the girl's eyes sparkle like stars, Sun Yuan was speechless and waved his hand.

What was all this about!

You're an upper-year student; do you really need to idolize a junior?

Admiration is one thing, but you don't need to show it so obviously!

"I saw him. He just got a form from me. He said he's going to challenge the Wall of Difficulties to earn some academic credits!" the girl nodded.

"Challenge the Wall of Difficulties to earn credits?" Sun Yuan was stunned for a moment, then couldn't help but shake his head.

The Wall of Difficulties, also known as the Wall of Complex Illnesses, was found in every Physician Guild.

It typically displayed complex and difficult-to-treat illnesses, encouraging future generations to solve them. In reality, very few, almost none, were able to complete them.

It was just like the record-breaking path in the Blacksmith School; countless people wanted to challenge it every year, but how many succeeded?

"That's right!" the girl nodded.

"I thought he'd go see Principal Zhao. I didn't expect him to challenge the Wall of Difficulties. What exactly is this guy up to?"

Puzzled, Sun Yuan was still wondering what the young man was planning when he heard a roar, like an earthquake, causing his feet to tremble slightly.

"What's happening?"

The Physician School was always sturdy; it wouldn't shake unless something unusual occurred.

"Hurry, go see! The Wall of Difficulties collapsed…"

"The Wall of Difficulties? That connects to the Physician Headquarters. How could it collapse?"

"I heard someone went in just now and solved all the difficult illnesses in less than ten minutes. It operated too fast; the wall couldn't handle it and collapsed…"

"Couldn't handle it?"

"That's right. The Wall of Difficulties uses high-grade spirit stones to process answers and information. Solving hundreds of difficult illnesses in ten minutes… you can imagine the speed. It operated too fast, too violently; it would be strange if it *could* handle it…"

As he wondered, a series of discussions erupted, and Sun Yuan immediately saw countless people rushing towards the Wall of Difficulties.

"The solving speed was too fast, and the Wall of Difficulties couldn't handle the load, so it collapsed?"

Sun Yuan's eyes widened, nearly going blind.

Is that real?

He had tried to solve the difficult illnesses on the Wall of Difficulties before; they were extremely challenging. Not just for him, but even his teacher would struggle to complete them. How could someone solve all of them in ten minutes?

"Could it be… Zhang Xuan?"

Suddenly remembering the girl's words, he couldn't help but look at her, seeing that her eyes were also wide.

"Did anyone else challenge the Wall of Difficulties today?" he quickly asked.

"No, just him…" the girl stammered.

"It really was him?"

His heart turned cold instantly, and he couldn't hold back any longer: "Let's go see!"

The two hurried towards the Wall of Difficulties and indeed saw that the previously tall passage had now become a pile of rubble, continuously emitting smoke.

A middle-aged man, disheveled and covered in dust, emerged from the ruins, looking utterly wretched.

"Teacher Hu, what happened?" Sun Yuan quickly went to meet him.

This Teacher Hu was his fellow disciple and was responsible for overseeing the Wall of Difficulties.

"It was that Zhang Xuan. He came to challenge the Wall of Difficulties and just solved all the complex illnesses in it… because the accumulated credits were too many to calculate, so… the passage collapsed!"

Teacher Hu's lips trembled as he hastily explained.

"Too many accumulated credits?" Sun Yuan was startled.

"That's right, you know how the Wall of Difficulties works. To encourage students to challenge it, the faster you solve them, the more credits you get. Solving one in an hour earns one credit; solving two earns three credits; solving three earns six credits, increasing in a one-plus-two-plus-three-plus-four progression…"

Teacher Hu explained.

Sun Yuan nodded.

The Wall of Difficulties indeed had such a regulation.

The faster one solved the problems and the more problems one solved, the higher the credits earned. This was also to improve students' speed in treating illnesses and saving lives in a shorter time.

"This Zhang Xuan solved over five hundred complex illnesses in five minutes… The credits were too much; all the academy's accumulated credits combined wouldn't be enough. Coupled with the mechanism operating too fast, it just turned into this…"

Teacher Hu explained.

"Not enough credits?"

Sun Yuan swayed, his vision went black, and he nearly fainted.

"Are you saying… he, he earned over a hundred thousand credits?"
