Douluo Continent: Thunder Roar

A classic technique came to mind—the Rasengan.

No hand seals are needed. Simply concentrate your energy in your palm and, through extreme rotation and compression, form a high-density, destructive energy ball.

This is essentially one of the ultimate manifestations of the "form change" of energy.

What if we used soul power to simulate this process instead?

In theory, any Soul Master could master similar techniques as long as they had precise enough control and a deep enough understanding of their Soul Power.

The only difference lies in the power that an individual can unleash.

This could be an interesting "experiment".

Thinking of this, Ling Yu looked at Wang Yan with a more inquisitive gaze.

He raised his right hand, palm up: "Teacher Wang, regarding self-created soul skills, I have a basic concept here. It doesn't rely on attributes, but only focuses on the form changes of soul power itself. Perhaps... it can explain some issues."

As soon as he finished speaking, an invisible soul force began to gather and rotate in his palm.

At first, there was only a slight disturbance in the airflow, but soon, a pale blue energy vortex, visible to the naked eye, began to emerge, emitting a low hum.

Wang Yan's pupils suddenly contracted.

He clearly sensed that there were no other attributes in that swirling energy; it was only the purest soul power, forcibly restrained and given a high-speed rotating form!

"This...this is..." Wang Yan's voice was somewhat hoarse, his body involuntarily leaning forward, his eyes fixed on the gradually stabilizing sphere of light. "Pure soul power transformation? Highly compressed and given directional rotation...theoretically feasible, but it requires an incredible level of control over soul power! Ling Yu, did you create this yourself?"

Instead of answering directly, Ling Yu asked, "Teacher Wang, do you think it's possible for other Soul Masters to master this technique? What are the main difficulties preventing Soul Masters from achieving this kind of precise control?"

He threw the question back at him, both as a question and a test.

Wang Yan fell into deep thought, his gaze fixed on the spinning sphere of light. After a moment, he took a deep breath, his eyes gleaming with the curiosity and caution characteristic of a scholar: "Ling Yu, theoretical deductions need practical verification. I wonder... if I could witness the power of this move firsthand? Of course, under the premise of ensuring safety."

Ling Yu nodded, his gaze drifting through the classroom window to a large, old tree with thick branches not far away. "Let's go outside."

The two arrived at the open space outside the classroom. The old tree had a sturdy trunk and mottled bark; it was a common tree species.

Wang Yan stepped back a few paces again, focusing intently.

Ling Yu flicked his wrist, and the steadily spinning pale blue ball of light in his palm emitted a clearer buzz. He didn't make any exaggerated movements; he simply pressed the Rasengan towards the tree trunk, seemingly casually.

laugh--!

A piercing sound of cutting and grinding rang out instantly! The moment the spinning energy ball made contact with the tree trunk, the solid wood was instantly shredded and carried away by the high-speed rotational force, turning into fine dust that drifted away!

A perfectly round hole, with smooth edges and several inches deep, appeared on the tree trunk in the blink of an eye.

The inner wall of the round hole shows a strange pattern that appears to have been evenly ground, with no cracks extending to the surrounding tree trunk.

It didn't even affect the stability of the tree; only the deep, round hole silently told the story of what had just happened.

The entire process was quick and quiet; the rotating energy ball dissipated silently after completing its penetration.

Wang Yan stood still for a long time without moving.

He stared blankly at the incredibly smooth round hole in the tree trunk, then looked at Ling Yu's withdrawn hand.

It wasn't an explosion, nor a brute-force slash; it was an extreme rotation and concentrated penetration... presenting the "destruction" of soul power in such an efficient and concentrated way...

"I need...to think about this carefully." Wang Yan's voice was somewhat unsteady. He pushed up his glasses, but his eyes shone with an astonishing light. "Ling Yu, thank you for today's demonstration. It gave me...a lot of inspiration. No, it was a revelation. Please excuse me."

He was clearly engrossed in a huge theoretical shock and thought, even somewhat absent-minded. He nodded to Ling Yu and then hurriedly left.

Ling Yu watched his retreating figure, then turned around and prepared to leave as well.

He had only taken a few steps when a figure blocked his way.

The newcomer was tall and slender, with an excessively beautiful face beneath short, light blue hair. She was currently standing with her arms crossed, looking at him with a displeased expression.

"You're too slow!" Wang Dong'er pouted, crossed her arms, and raised her chin slightly. "You went to discuss life ideals with Teacher Wang Yan? You made me wait so long."

Ling Yu shrugged, his tone calm: "I don't think I made you wait for me."

"Hey! What kind of attitude is that!" Wang Dong'er immediately caught up with him, walking alongside him, her feigned dissatisfaction even more obvious. "At least... at least we're roommates, right? What's wrong with walking together?"

Ling Yu didn't reply and continued walking towards the cafeteria.

Seeing that he ignored her, Wang Dong'er was not discouraged, but instead relaxed her posture.

She put her hands behind her back, her fingers unconsciously hooking slightly, and her steps became lighter. She tiptoed slightly and occasionally kicked a small pebble that wasn't actually on the road.

Clearly, she wasn't as impatient as she appeared; on the contrary, she seemed quite cheerful.

"Wang Dong," Ling Yu suddenly spoke, his voice flat and emotionless.

"Huh? What? What?" Wang Dong'er immediately perked up her ears, paused for a moment, and leaned slightly towards Ling Yu, her beautiful eyes filled with curiosity—this taciturn guy actually took the initiative to start a conversation?

"Has anyone ever told you," Ling Yu turned his head, his gaze sweeping over her hands behind her back and her light steps, his tone carrying a hint of barely perceptible inquiry, "the way you walk..."

He paused.

Wang Dong'er's heart skipped a beat for no apparent reason, and she blinked, waiting for what would happen next.

"Does she look a bit like a young girl?"

"—!!!"

Wang Dong'er's body froze instantly, the relaxed and happy expression on her face froze, and then a thin layer of red quickly spread from the tips of her ears to her neck.

She is now "Wang Dong"!

It's Lingyu's "male" roommate!

If this guy sees through me, what will happen?!

"What nonsense are you spouting!" Wang Dong'er abruptly lowered her hands from behind her back, clenching them into fists. Her voice rose slightly from embarrassment and guilt, and her eyes darted around, avoiding Ling Yu's gaze. "I...I'm just...I'm agile! I'm...I'm in a good mood! What do you know! Stop talking nonsense!"

Ling Yu shrugged slightly and didn't say anything more.

This reaction relieved Wang Dong'er, but also left her with a vague sense of disappointment. She could only pretend to fix her hair to hide the blush that had not completely faded from her face.

Lunch was spent in a subtle quiet.

Back in his dorm room, Ling Yu went straight to his bed, sat down cross-legged, and prepared to enter a meditative state.

A lot of time has already been wasted this morning because of Zhou Yi and Wang Yan's delays.

After his afternoon classes, he planned to go to Shrek City to find a suitable storefront to reopen his clinic.

Since the eldest brother cannot sense the aura of the Sea God's divine consciousness on Wang Dong'er for the time being, he should proceed at his own pace and not waste too much extra energy on her.

Just as he was about to immerse himself in cultivation, Wang Dong'er's voice suddenly rang out, carrying a hint of feigned ease, yet concealing a subtle coyness:

"Hey, Ling Yu... I'm a magnanimous person, and after thinking about it, those five rules I mentioned before... can be cancelled." She paused, glancing elsewhere. "Consider it a sign of acknowledging you as my roommate. Um... you don't need to move out anymore. Moving around is quite troublesome, and it's inconvenient to run around to class every day."

She tried to make her tone sound confident and self-assured, as if she were considering the other person's feelings, but her slightly reddened ears and somewhat clumsy fingers betrayed her.

After all, as a girl, it's hard not to feel a little embarrassed and strange for her to take the initiative to ask a boy to stay and "live together," even if it's just as a roommate.

Upon hearing this, Ling Yu slowly opened his eyes and looked at her calmly.

"No need." His voice was flat. "I'll be moving out in the next few days."

Wang Dong'er's feigned composure froze instantly, a clear hint of disappointment flashing across her eyes. "W-why?" she asked instinctively, her voice carrying a hint of urgency and grievance she herself didn't realize, "Do...do you think I'm that annoying?"

"A little," Ling Yu replied succinctly and directly.
