Chapter 803: One Hundred Thousand Credits?

"Not selling?" Hearing those exact words, Zhang Xuan's face turned ashen.

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

After all that talk, he still refused to sell?

Truly, when a master teacher is shameless, they are more terrifying than a sacred beast from Cloudmist Ridge!

"Indeed!" Vice Dean You waved his hand. "I'm not in the habit of selling immature goods. You may leave!"

Knowing that without the Ten-Leaf Flower, Wei Ruyan's life hung by a thread, Zhang Xuan suppressed the fury threatening to burst from his chest. "Do you mean that if it were mature, you would sell it?"

"Correct!" Vice Dean You nodded. "How can I sell an immature herb? You should understand the reasoning; I'm not deliberately making things difficult!"

"Very well. Since you won't sell it immature... I'll make it mature right now!"

Casting a cold glance at the other, Zhang Xuan turned and approached the Ten-Leaf Flower in the medicinal garden. With a flick of his finger, a few drops of Earth Vein Spiritual Liquid seeped into it, followed by the infusion of Heavenly Dao true energy.

If he only nourished it with Earth Vein Spiritual Liquid, the Ten-Leaf Flower could mature quickly, but it would take about a day. With the aid of Heavenly Dao true energy, the speed increased significantly.

Indeed, as the true energy and spiritual liquid entered, the Ten-Leaf Flower grew visibly. In about ten minutes, the ten buds fully bloomed, releasing a stunning fragrance.

"This..."

Sun Yuan's eyes widened.

The Ten-Leaf Flower was a sacred herb; under normal circumstances, it took ten years to mature. He had done it in ten minutes... How?

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

Zhang Xuan stood up.

Vice Dean You's face turned green.

He said to trade with Cloudmist Flower—the other brought it; he said it wasn't alive—the other revived it; he said the herb wasn't mature—the other ripened it on the spot... This guy wasn't here to buy medicine; he was here to slap his face!

"What? Now that the Ten-Leaf Flower is mature, Vice Dean You doesn't want to sell it?" Seeing his expression, Zhang Xuan looked over.

"Hmph! This Ten-Leaf Flower was raised by my own hands. If I say I won't sell it, do you dare to take it by force?" Vice Dean You raised an eyebrow.

"Taking by force from a vice dean? Of course I wouldn't dare!" Zhang Xuan shook his head, his gaze sharp as lightning. "I'll ask you one last time: are you sure you won't sell it to me?"

"Indeed! My Ten-Leaf Flower, even if it rots in the ground, I won't sell it to someone like you who shows no respect for elders and breaks the rules!" Vice Dean You snorted.

"Very well!"

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

"He left?"

Sun Yuan stood frozen, expecting the guy to do something outrageous. Instead, he just left. After a moment, he couldn't help but look at the dean before him. "Teacher, it's just a Ten-Leaf Flower. Since he wanted to buy it, why not just sell it to him? Why make things so tense..."

"Insolent! What, your wings are hard, and you want to lecture your teacher?" Vice Dean You's brows shot up.

"Student wouldn't dare!" Sun Yuan clasped his fists. "I've just heard many things about this guy. They say he's quite uncanny. I'm afraid... offending him completely might bring trouble!"

"Ridiculous! I, You Xu, a Saint realm expert and vice dean of the Physician Academy, have weathered many storms. Am I supposed to fear a student?" Vice Dean You sneered coldly.

"But..." Sun Yuan was full of worry.

There must be a reason why this guy was so highly regarded by Mo Gaoyuan, Dean Mi, Dean Zhao, and Dean Wei Ranxue. If his teacher rashly offended him, might it offend those deans, or even the head of the Master Teacher Hall?

"No buts. Like this... follow him and see. If that brat speaks ill of me in front of Dean Mi and the others or spreads any false information, arrest him immediately and charge him with slandering a high-level master teacher!"

Vice Dean You snorted.

"This..." Sun Yuan hesitated.

"Go quickly! A low-level master teacher speaking recklessly about a high-level one is a grave offense. If this guy dares to talk nonsense in front of others, he's asking for death!" Vice Dean You waved his hand.

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

A low-level master teacher, without solid evidence, speaking recklessly about a high-level one was a violation. This Zhang Xuan was only a four-star, while his teacher was a peak six-star—two levels apart. If he really dared to speak recklessly, he could indeed be arrested on the spot.

Leaving the courtyard, he looked around and caught sight of Zhang Xuan, who had just left and hadn't gone far. He quietly followed.

Though he didn't entirely agree with his teacher's approach, a teacher's command was hard to defy, so he strictly obeyed.

"Will he go to Dean Mi or Dean Zhao first?"

Following from a distance, he speculated.

He had heard much about this Zhang Xuan. Whether Dean Mi, Dean Zhao, or Dean Wei, all treated him as a distinguished guest. If he wanted to cause trouble, he would surely seek one of them.

However, even if those three were highly respected, they belonged to different academies. At most, they would act as mediators and shouldn't do much to his teacher.

"I think it's more likely he'll go to Dean Zhao. The Artifact Refiner Academy ranks second and values him more..."

Muttering to himself, just as he was pondering whom the other would complain to, he saw the young man ahead turn and stride straight into the Physician Tower.

"Hmm? Going to the Physician Tower for what?"

He blinked.

In his view, shouldn't this young man seek out the deans to complain and cause trouble for his teacher? Why was he heading to the Physician Tower instead?

"Let's go see!"

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 without finding him. Finally, he couldn't help but go to the front desk.

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

It was the same girl who had taken Zhang Xuan to the detached courtyard that day.

"Mm, have you seen that 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's Zhang Xuan?" The girl covered her mouth, eyes wide with excitement, as if meeting an idol.

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

"Ahem! Have you seen him?" Seeing the stars in the girl's eyes, Sun Yuan was speechless and couldn't help waving his hand.

What was this?

You're a senior student; why worship a junior?

Admiration is fine, but did you have to show it so obviously?

"I saw him. He just got a form from me, saying he wanted to challenge the Wall of Difficulties to earn some credits," the girl nodded.

"Earn credits at the Wall of Difficulties?" Sun Yuan was stunned for a moment, then couldn't help shaking his head.

The Wall of Difficulties, also called the Wall of Knotty Problems, existed in every Physician Guild.

Usually, intractable diseases and problems were posted there to encourage later generations to solve them. But in reality, those who could solve them... were few and far between, almost impossible.

It was like the record passage in the Artifact Refiner Academy—countless people tried each year, but how many succeeded?

"Yes!" The girl nodded.

"I thought he'd go to Dean Zhao, but instead he comes to challenge the Wall of Difficulties. What is this guy up to?"

Full of curiosity, Sun Yuan was wondering what the kid was doing when he heard a rumble like an earthquake, making the ground tremble.

"What's going on?"

The Physician Academy was always sturdy; it wouldn't shake unless something happened.

"Quick, go see! The Wall of Difficulties has collapsed..."

"The Wall of Difficulties? It's connected to the Physician Headquarters. How could it collapse?"

"I heard someone entered and solved all the knotty problems in less than ten minutes. It ran too fast, and the wall couldn't take it, so it collapsed..."

"Couldn't take it?"

"Yes, the Wall of Difficulties runs on high-grade spirit stones to process answers and information. Hundreds of knotty problems solved in ten minutes—you can imagine the speed... Running too fast and too fiercely, of course it couldn't hold up..."

...

While he was wondering, a series of discussions arose, and Sun Yuan saw countless people rushing toward the direction of the Wall of Difficulties.

"Solved too fast, the Wall of Difficulties couldn't handle it and collapsed?"

Sun Yuan's eyes widened; he almost went blind.

Was this for real?

He had tried to solve the knotty problems on the Wall of Difficulties. They were extremely hard. Not even his teacher could complete them. How could anyone solve them all in ten minutes?

"Could it be... Zhang Xuan?"

Suddenly recalling the girl's words, he couldn't help looking at her, and saw that her eyes were also wide.

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

"No, just him..." The girl trembled.

"It's really him?"

His heart turned cold. Unable to hold back, he said, "Let's go see!"

The two hurried to the Wall of Difficulties and indeed saw that the once-tall passage had become a pile of rubble, still emitting green smoke.

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

"Teacher Hu, what happened?" Sun Yuan quickly approached.

This Teacher Hu was his junior fellow apprentice, responsible for overseeing the Wall of Difficulties.

"It was that Zhang Xuan. He came, challenged the Wall of Difficulties, and solved all the knotty problems... Because the accumulated credits were too many to calculate, the... passage collapsed!"

Teacher Hu's lips trembled as he explained.

"Too many accumulated credits?" Sun Yuan was taken aback.

"Yes, you know how the Wall of Difficulties works. To encourage students to challenge it, the faster they solve problems, the higher the credits. Solve one in an hour, get one credit; solve two, get three credits; solve three, get six credits—it increases like one plus two plus three plus four..."

Teacher Hu explained.

Sun Yuan nodded.

The Wall of Difficulties indeed had such a rule.

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

"This Zhang Xuan solved over five hundred knotty problems in five minutes... The credits were too many; all the credits in the academy combined weren't enough. Plus, the mechanism ran too fast, so this happened..."

Teacher Hu explained.

"Not enough credits?"

His body swayed, and Sun Yuan's vision went dark. He nearly fainted.

"Are you saying... he, he earned over one hundred thousand credits?"
