Lv Yongchang's pupils contracted slightly as he met the frowning gaze of the elderly man at the podium. Professor Guan Hualiang! Hadn't he passed away five years ago?"Lv Yongchang! This is your first college physics class! If you hate physics so much, why enroll in the physics department?!" Guan Hualiang's voice seethed with anger.Dazed, Lv Yongchang stood abruptly, scanning his surroundings. The familiar scene... This was his university classroom! If his memory served, this was his sophomore year's first physics lecture! He quickly pulled out his phone and lit up the screen.September 6, 2030Re... Reborn?In an instant, countless complex emotions flooded Lv Yongchang's mind—confusion, sorrow, loss, and a flicker of hope! His name, Yongchang, derived from the ancient seal inscription "Bestowed by Heaven, Eternal Prosperity". Ironically accurate, as in his past life he'd held humanity's highest position, yet his miscalculations led to total extinction. This time, he would reverse everything!But how?"Lv Yongchang! Are you even listening to me?!" Professor Guan's face reddened with fury. After decades of teaching at Sandao'ou University, he'd never encountered such disrespectful behavior.Lv Yongchang stared at the professor and the blackboard behind him, his eyes sharpening. Perhaps... he needed a moment to shock the world!In the next instant! The neon-green tree diagram's countless formulas and symbols surged through his mind like a tempest.
"Lv Yongchang! What are you doing?!"
Professor Guan Hualiang's face paled as he watched Lv stand and stride toward the podium.
"This is a classroom! Get ahold of yourself!"
Guan's reprimand triggered a wave of nostalgia in Lv Yongchang. It's been over a decade since I last heard that tone.
A faint smile crossed Lv's face as he nodded at the professor. "I'm sorry, Professor Guan. I need to borrow the blackboard."
Guan's shock turned to fury. In all his years of teaching, no student had ever "borrowed" his blackboard mid-lecture! Before he could protest, Lv reached past him, grabbed a whiteboard marker, and began writing.
Guan laughed in disbelief. This isn't borrowing—it's stealing!
"Mr. Lv, this is your final warning..." Guan took a deep breath, struggling to contain his anger. "Return to your seat now, and I'll overlook this incident. If—"
Lv straightened, meeting Guan's gaze with unwavering resolve. The professor froze, suddenly reminded of his own mentor's ironclad authority. But this is just a sophomore student!
The entire class stared in disbelief.
"What... the hell? Is Lv Yongchang crazy?!" Wu Qi, Lv's bespectacled roommate, whispered in shock. "Does he want to get expelled?!"
Lv ignored the commotion. Turning to the blackboard, he began writing with fierce determination.
The first equation appeared—neat, precise, and far beyond undergraduate level. Guan's irritation faded, replaced by curiosity. Where did he learn this?
As more formulas and diagrams emerged, Guan's eyes widened. Controlled nuclear fusion? His anger dissolved into excitement. This is genius!
Just as Guan prepared to congratulate him, Lv paused.
"No more space..."
Without hesitation, Lv turned to the projector screen and began writing there, despite the marker's poor adhesion. Words poured out—a revolutionary new material design.
Guan paled. I've never seen anything like this! His 科研直觉 (scientific intuition) screamed: This must be classified!
"Everyone, put down your phones!" he snapped. "No recording. No one leaves this classroom."Half an hour later.
Lv Yongchang slowly lowered his marker.
"These later sections—this is a new material synthesis method?" Professor Guan's voice trembled.
Turning, Lv nodded calmly. "Yes."
He glanced at the dumbfounded students before lowering his voice. "Professor, this material can solve the core problem of controlled nuclear fusion."
Guan's pupils dilated. The greatest obstacle to fusion was the billion-degree temperatures generated during reactions.
He stared at the projector screen covered in equations. "What... what is its function?"
Though a physics professor, Guan lacked expertise in materials science. Still, fusion—the dream of clean, limitless energy! Despite lingering doubts, the meticulous calculations erased his skepticism.
This wasn't undergraduate work. This was the precision of a seasoned scientist.
"Capable of indefinitely containing fusion plasma when paired with a stellarator," Lv's eyes gleamed with resolve. "Professor, I need your assistance to verify these calculations."
