Little Yue'er saw that someone had welcomed Lin Yun, so she said first, "Master Uncle, I will head back now. If you need anything in the future, feel free to find me at the Chore Department."

"Alright, thank you for taking me here." Lin Yun was quite pleased with Xiao Yu, turned, and smiled warmly. Xiao Yu, delighted upon seeing Lin Yun's satisfaction, felt embarrassed and left cheerfully.

"Master Uncle, have you ever taken an aptitude assessment before?" The registrar blinked several times, waiting for Lin Yun's response.

"No..." Lin Yun smiled gently.

The registrar was astonished, almost stumbling, but quickly composed himself and continued to ask, "Master Uncle, surely you are aware of your qualification level?"

"Well... I honestly don't know!" Lin Yun replied awkwardly.

The registrar's smile froze for a brief moment. He laughed uneasily and said, "As a newly accepted disciple, it's perfectly normal not to know. Qualification levels, often referred to as the aptitude categories in Meditation University, determine the upper limit of what techniques can be practiced in the future. Still, these levels should merely be taken as references and not overly emphasized. Many high-level Meditators tend to become complacent due to their superior qualifications, resulting in achievements far behind those of lower-ranked yet diligent cultivators. In the end, personal effort is what truly matters."

Lin Yun nodded slightly, gaining some understanding—he believed this might align with the saying "The heavens reward the diligent." If one practices persistently, success will naturally follow someday.

"Qualifications are divided into four ranks: Heaven, Earth, Xuanyuan Huang, and Yellow. Each rank is further subdivided into three stages: Beginner, Advanced, and Peak. Heaven rank is the highest, while Yellow rank is the lowest."

Following the explanation, the registrar led Lin Yun to the second floor. At the center of the second-floor hall stood a 15-foot-high crystal glowing with a captivating blue light. Its brilliance was both striking and powerful.

"This is the Spirit Stone test, made using deep-sea crystal stone known for its coldness, which can evaluate a person's aptitude. Hence, it is called the Spirit Stone test. Master Uncle, please step forward." The registrar gestured for Lin Yun to circle the stone. The crystal stood suspended about half a foot above the ground, resembling an oversized peach pit. Ice-like crystals constantly spread across its surface, radiating an aura of elegance unmatched by anything Lin Yun had seen.

"Master Uncle, place your hand on the Spirit Stone's surface. It will reveal your aptitude." The registrar demonstrated by laying his hand on the rock's surface. Moments later, with a crisp sound, a radiant blue light enveloped the stone, and bold azure characters appeared a foot in front of the stone.

"Yellow Peak!" This was the registrar's qualification.

The registrar's face blushed, embarrassed by the quality of his aptitude.

"Master Uncle, go ahead and try—it might be similar to mine." The registrar removed his hand from the Spirit Stone, causing the Yellow Peak grade to fade after 20 minutes.

Lin Yun nodded and stepped forward. Following the registrar's actions, he placed his hand lightly on the stone's surface. A sudden cool sensation swept across his entire body. Soon, four large characters appeared: "Yellow Stage - Peak."

"Hmm..." The registrar mumbled incredulously, staring at the results lingering for 20 minutes. "How is it possible for the aptitude to be Yellow Stage Peak? Is the stone broken?"

The registrar hesitated, suspecting the stone had malfunctioned. He muttered to himself, "How could the qualification level for a disciple from Star University be merely Yellow Stage Peak? The bare minimum should be Earth Stage or higher. If not, why would the Star Lord willingly accept such a poorly qualified disciple and invite unnecessary trouble?"

Lin Yun reacted differently, blinking a few times at the results that remained for 20 minutes—Yellow Peak—now displayed as his aptitude level.

"This... it can't be right. Did something happen to the Spirit Stone? How could Master Uncle's qualifications be so low?" The registrar's disbelief was evident.

"Ah, to be honest, I'm not certain either." Lin Yun wasn't overly concerned about qualification ranks and simply chuckled.

"It must be a problem with the Spirit Stone. Otherwise, how could Master Uncle's aptitude possibly be Yellow Stage Peak?" The registrar examined the stone from all angles, searching for any signs of malfunction. After several rounds of inspection, however, he couldn't find any issues.

"Perhaps I'm missing something due to lack of expertise!" The registrar scratched his calloused hands, still puzzled.

Lin Yun found it peculiar that Xuan Kui paid little attention to the aptitude test results. Why had Xuan Kui gone to such lengths to accept him as a disciple? Was it because of the mysterious jade stone in his possession? Could Xuan Kui already know about the secret of the Mystic Jade?

These thoughts prompted Lin Yun to speculate further. The possibilities unnerved him—his mind raced with fear. But then he reconsidered: if Xuan Kui truly knew he carried the Mystic Jade, wouldn't he have already killed him to extract it? Under such circumstances, Lin Yun surmised that becoming a disciple might have been his safest move.

"Alright, Master Uncle, let me take you to receive a beginner-level meditation manual and start your training." The registrar, unable to uncover any issues with the Spirit Stone, decided it was a waste of time to dwell further. He shifted his focus to something more productive.

This time, Lin Yun followed the registrar to the third floor. On the third floor were rows upon rows of shelves filled with manuals for beginner, intermediate, and advanced meditation techniques. As a newly initiated disciple, Lin Yun was only allowed access to beginner-level manuals. These techniques were the hard-earned knowledge of predecessors, crafted to enhance a cultivator's meditation skills. Many techniques could improve attack strength, boost defensive power, or even specialize in unique forms of combat.

For example, the "36 Locks" technique—practicing "36 Locks" could increase a Zen Practitioner's attack power by 150%.

Lin Yun browsed the shelves but felt that most beginner techniques weren't quite suitable for him. That was until his gaze landed on a dusty book tucked away in a corner—its neglected condition made Lin Yun's eyes light up. The moment he saw its title, he felt a strange sense of gravity.

"Sterility..." Lin Yun read the book's title, noticing the thick layer of dust. Clearly, it hadn't been touched in ages. As he pulled out the book, his actions stirred a cloud of dust, causing him to sneeze repeatedly. The book seemed remarkably unpopular.

How peculiar. What kind of mysterious manual would remain untouched for so long? Lin Yun was intrigued by the oddity of the situation. He eagerly grabbed the book and left the building.

Seeing Lin Yun emerge, the registrar hurried to greet him. "Master Uncle, which book did you pick?" he inquired.

"This one... 'Sterility!'" Lin Yun held up the book, its cover now dust-free and gleaming.

"Sterility? What an unusual name!" The registrar had never heard of such a book during his years overseeing the third-floor library.

"Master Uncle, this is your Mediterranean token." The registrar handed over a purple medallion. "The Mediterranean token signifies a disciple's identity in the outside world. With this, you can accept various external tasks, most of which reward valuable Spirit Stones." Lin Yun received the token, feeling its surprising weight but unable to discern its material composition.

"Alright, everything is ready now, Master Uncle. Let me show you to your accommodations." The registrar, exhausted from the process, stretched lazily, his spirit lightened by wrapping up his duties.

Lin Yun nodded in agreement and followed the registrar to a nearby mountain, where a spacious courtyard awaited. The setting was serene, complete with artificial hills, gardens, and ponds.

"Master Uncle, this will be your temporary residence. It's the best accommodation for disciples here. After you are summoned by the Star Lord, you can move to the Star Hall. The conditions there are significantly better than here." The registrar bid farewell to Lin Yun and returned to the registration office.

After parting with the registrar, Lin Yun strolled around the courtyard several times. The environment was far superior to that of Yunfu. The surroundings were brimming with Spiritual Energy, and he felt calm as he began meditating quietly to refine his inner strength.
