"Attend class!"

Ye Kai strode into the classroom, placed the books on the desk, and looked around at the students.

"Hello, teacher..."

The students greeted him in unison. Their expressions were mixed—some were curious, others puzzled, and a few impatient. Everyone had different thoughts about the new teacher.

"Students, please sit down!"

Ye Kai nodded slightly, taking in the varied expressions of the twenty-four students in the class. He knew exactly what they were feeling and had anticipated this reaction long ago. Regardless, he intended to teach according to his own methods.

"I believe everyone is still unsure about me, a teacher transferred from Shanghai University, but we have plenty of time to get to know each other, so I won’t introduce myself in detail."

"Just to put it simply, my name is Ye Kai, and I used to be a professor in the Department of Theory at Practitioner University in Shanghai."

As he spoke, Ye Kai wrote his name on the blackboard: **Ye Kai**. The two characters were bold and powerful, revealing a unique charm. However, none of the students paid attention to the writing. Instead, they were completely captivated by his words.

"A professor at Practitioner University in Devil's City? Wow! What kind of legendary teacher is this?!"

"Are you kidding me? That’s one of the top three Martial Dao colleges in the country—a holy place that many students dream of attending!"

"When did Qingcheng No. 3 Middle School become so incredible? They even invited a professor from the Holy Land of Martial Dao!"

"Teacher, don’t exaggerate!"

The classroom buzzed with excited discussions, so loud that the noise spread into the hallway. The students were clearly thrilled.

Boom boom boom!

Ye Kai remained expressionless as he knocked on the podium three times with his book. Instantly, under the intimidating aura of the Shanghai University professor, the students quieted down and looked at him in unison.

"As for my identity, you can discuss it later. Today, I’m here for my first class!"

*Swipe!*

The sound of chalk rubbing against the blackboard filled the room as three new characters appeared under Ye Kai's name: **Practice Method**.

"You are all high school seniors preparing for the martial arts exam. You should be very familiar with the history of the world and the birth of the Practitioner, right?" Ye Kai asked, putting down the chalk and looking at the students with questioning eyes.

"I know! I’ve memorized that section of history from the textbook!"

"A few hundred years ago, the world changed drastically, and the earth's veins miraculously revived on this doomed planet, causing all creatures to evolve rapidly. In just one year, humans were dethroned as the rulers of the earth by other animals and plants!"

"For over a decade, humanity struggled through a cruel, dark era until, after the tireless efforts of the great ancestors..."

"The vitality cultivation method was born, and the Practitioner profession emerged!"

One eager student, trying to show off in front of Professor Ye Kai, quickly recited the preface from the history textbook.

Ye Kai glanced at the student’s face and recognized him from the student files. His name was Li Zi, a top student. Nodding in acknowledgment, Ye Kai motioned for him to sit down.

"The vitality cultivation method is indeed the cornerstone of humanity, created by our ancestors through countless efforts. Its main principle is to introduce vitality into the body, strengthening human blood, and helping practitioners to break through the limits of the human body."

The students nodded in agreement. They practiced this Practitioner system every day, and it had become second nature to them.

"This system has been developed over hundreds of years, with dozens of generations building upon it, and it has reached its peak!" Ye Kai paused for a few seconds, drawing everyone’s attention before continuing.

"But have you ever considered that there might be a cultivation method even more suitable for the human race than the vitality cultivation method?"

"This cultivation method can be practiced by anyone, and just by initiating it, one can wield terrifying power. Its upper limit is incredibly high, enough to create countless peak powerhouses and secure the human race’s supremacy..."

Ye Kai’s persuasive words stirred a commotion among the students.

"How could there be a system more suitable for humanity than the Practitioner system? Even that system doesn't offer the accessibility and comprehensive benefits of the current one!"

"Exactly! Even if such a system exists, it wouldn’t be available now—it would be something from the distant future!"

"No way! It’s impossible! The Practitioner system is already the most effective body refining method for humanity!"

"Teacher, as a professor at Practitioner University in Shanghai, you can’t seriously believe this, can you?"

Ye Kai expected their skepticism. With a slight smile, he added two more words on the blackboard amidst the students' murmurs.

In front of **Practice Method**, he wrote: **Shrouding the Heavens**.

"Perhaps it didn’t exist before, but now, it does!"

"The Shrouding the Heavens cultivation method is the one that can make every human a dragon, powerful enough to suppress all other races!"

After his words fell, the entire classroom went silent...
