Truth Doctor, Spirit Hall's Live-In Son-in-Law

Spirit City, Spirit Hall Advanced Soul Master Academy, inside a classroom.

More than twenty young men and women, around twenty years old, chatted during class. All of them were genius Soul Masters nurtured by Spirit Hall.

Their Soul Power had all surpassed that of a Soul Elder, and three of them had even been hailed by Spirit Hall as the Golden Generation!

"Ah... It's Dr. Ratio's class again. I hope he doesn't give me a zero this time! The way Dr. Ratio looks at me makes me feel like an idiot!"

"Can Dr. Ratio take off that Plaster Head Sculpture this time? I really want to see his real face..."

"I heard Dr. Ratio is the Angel Clan's son-in-law!"

"..."

The students chattered away, with Dr. Ratio at the center of every conversation.

Among them was a girl with orange bobbed hair. Her bright eyes and white teeth, along with the alluring charm radiating from her clean, lovely face, drew many male students to steal glances at her.

"Na Na, you saw Dr. Ratio's real face before. Is he really that handsome?"

Several girls looked curiously at Hu Liena.

Dr. Ratio, whom they spoke of, was a famous "live-in son-in-law" of Spirit Hall.

No one knew who his wife was. They only knew that he held a highly unusual status within Spirit Hall!

At the same time, Dr. Ratio always wore a Plaster Head Sculpture, concealing his true appearance.

Yet the strange fragrance around him and his tall, well-built frame made everyone eagerly anticipate the face beneath that Plaster Head Sculpture. He had to be an exceptionally beautiful man.

But even more astonishing than Dr. Ratio's appearance was his talent!

Dr. Ratio was known as Spirit Hall's most learned Grandmaster!

Even old scholars who had spent their entire lives studying Soul Power spoke of Dr. Ratio with wholehearted admiration.

They all said, "Dr. Ratio is a theoretical Grandmaster without equal, before or since!"

Yet Dr. Ratio always called himself an "ordinary man."

Of course, if Dr. Ratio considered himself ordinary, then his attitude toward all those ordinary people inferior to him went without saying.

The genius students of Spirit Hall in this classroom had only attended three of Dr. Ratio's lessons.

Half had failed, while four students had become so discouraged that they wanted to drop out!

That showed just how strict Dr. Ratio was in his teaching!

And today was Dr. Ratio's fourth class!

Hu Liena narrowed her eyes, seemingly lost in recollection.

Yan, seated at the desk behind her, curled his lip and snorted. "What's so great about him? He's just an ordinary person who doesn't even have a martial soul..."

"Shut up! Dr. Ratio is coming!"

Xie Yue suddenly appeared at the doorway and called out softly.

In an instant, every student returned to their seats and sat properly.

Yan curled his lip, his face full of defiance.

He was already prepared. During class, he would definitely make things difficult for Dr. Ratio.

Who told that man to fail him?

"Rustle, rustle, rustle..."

A light breeze swept through.

A fragrance drifted into the classroom, instantly clearing every student's mind.

It was neither ordinary perfume nor body scent.

If it had to be explained, it was perhaps... the fragrance of knowledge?

Everyone gazed expectantly toward the doorway.

A second later, a foot stepped into the classroom.

It belonged to a tall man over six feet tall. His clothing was primarily blue and purple, revealing his fit, sculpted muscle lines—enough to make lustful women drool at the sight.

...It was said that Dr. Ratio received at least ten love letters every day!

And atop the man's head was, unmistakably, a Plaster Head Sculpture, completely hiding his original face.

His entrance made many female students sigh inwardly.

They truly wanted to see Dr. Ratio's real face!

Ratio walked to the podium, swept his gaze around the room, and felt rather complicated.

He had first transmigrated to Honkai Star Rail, earned eight doctoral degrees and one first-class honors degree, independently resolved a planetary energy crisis, and cured the king of all illnesses, Petrification Disease—only to transmigrate again to Douluo Continent.

And through a strange twist of fate, he had become Qian Renxue's live-in son-in-law.

Still, none of that mattered. Changing worlds was no different from changing planets.

He was quite interested in this world's power system, Soul Power.

At the same time, he had not forgotten his old profession: Truth Doctor!

He firmly believed that wisdom and creativity were not the sole domain of geniuses. He was dedicated to spreading knowledge throughout the universe and treating the chronic ailment known as stupidity.

Drawing in a quiet breath, Ratio collected his thoughts.

He had never allowed such complicated emotions to affect him.

Through the Plaster Head Sculpture, he could clearly see the world outside.

These bright-eyed students were filled with pure, unclouded stupidity.

Perhaps this world needed saving by him even more.

With that thought, Ratio picked up a piece of chalk, turned around, and wrote several large words on the Blackboard.

"Ten Core Competencies Theory."

Ratio felt that treating the chronic ailment known as "stupidity" was exceedingly difficult.

This disease was extraordinarily hard to cure. After all, there were few geniuses in the universe but many fools. The latter could not stroll among the stars as geniuses did. They could only learn to walk on their own, spending their mediocre lives falling down, getting back up, falling again, and rising once more.

And he was compassionate; he could not bear to watch fools endlessly repeat this tedious process.

Now, he would vividly show these fools the gap between themselves and geniuses.

Naturally, a Grandmaster's theories would serve as negative examples.

By "looking in the mirror," they could at least broaden their horizons.

Pope's Palace, main hall.

Bibi Dong sat upon her throne, one long, slender leg crossed over the other. She leaned back slightly, her curvaceous figure displaying breathtaking lines.

She was a peerlessly beautiful woman!

Yet no man dared admire that beauty openly.

A faint look of worry appeared on Bibi Dong's face.

"That idiot Qian Daoliu actually thought Ratio was a reincarnated god. Yet he hasn't even awakened a martial soul. If he absolutely must be connected to a god, then he should be some kind of divine punisher!"

The thought of Ratio gave Bibi Dong a headache.

Her nominal son-in-law often gave her the illusion of Yu Xiaogang.

Especially since he had also gained the title of theoretical Grandmaster.

The more she looked at him, the more irritated she became!

"Find a way to drive him away..." Bibi Dong opened her eyes, a resolute glint flashing through them.

Just then.

A figure suddenly darted into the main hall.

It was Chrysanthemum Douluo. He bent at the waist in the hall, not daring to look at Bibi Dong atop the raised platform.

"Your Holiness the Pope, Dr. Ratio is teaching... teaching the Ten Core Competencies Theory in class..."

Chrysanthemum Douluo's voice trembled slightly.

The Ten Core Competencies and anything connected to Yu Xiaogang were taboos within Spirit Hall.

Now that Dr. Ratio had touched upon it, he had to report it to the Pope.

Bibi Dong's expression turned cold. "I said it before! No one is allowed to mention that..."
