Douluo Continent: Thunder Roar

The theory class ended in a subtle atmosphere.

Wang Yan's explanation was solid and clear, but many freshmen's eyes still kept drifting to the quiet figure by the window.

When the bell rang, Wang Yan closed his lesson plan, his gaze sweeping gently across the classroom before finally settling on Ling Yu.

"That concludes this morning's classes. Ling Yu," he adjusted his glasses, his tone calm, "Please stay a moment; there's something I'd like to discuss with you."

The other students looked at Ling Yu with curiosity or awe, and then left the classroom one after another.

Wang Dong'er walked to the door, hesitated for a moment, and turned back to look at Ling Yu.

Ling Yu shook his head at her almost imperceptibly, and she pursed her lips, turned around and left.

Soon, only the two of them remained in the large classroom.

The afternoon sun slanted in, casting the shadows of window panes on the polished floor. Fine dust floated in the air, making it exceptionally quiet.

Instead of standing on the podium, Wang Yan picked up his lesson plan, walked to the seat next to Ling Yu, and sat down naturally, placing the lesson plan on the empty table beside him.

This move reduced some of the distance between superiors and subordinates.

"Ling Yu," he said, getting straight to the point, his tone still gentle, but his gaze behind his glasses held a clear inquisitiveness, "First of all, regarding the incident that occurred at the training ground this morning, the academy will investigate and evaluate it according to the relevant procedures. You don't need to worry too much. Many people witnessed the cause and process of the incident, and the truth will be judged by public opinion."

He paused, observing Ling Yu's reaction.

Ling Yu simply sat quietly, his face showing no particular emotion, neither apprehension nor arrogance, calmly waiting for what would follow.

"My decision to keep you here is more out of personal interest." Wang Yan leaned forward slightly, his hands clasped on his knees, adopting a posture more like that of a colleague preparing to discuss academic matters. "I'm obsessed with the study of martial spirit theory. Witnessing your battle today, especially the unique and powerful display of your martial spirit, has sparked many thoughts in me, and you could even say it has challenged some of my preconceived notions. If you don't mind, I'd like to discuss this with you; this is purely an academic exchange."

Ling Yu nodded, his voice steady: "Please speak, Teacher Wang. I will answer any question I can."

"Okay." Wang Yan's eyes brightened slightly upon receiving permission. "Based on my observation and analysis, the manifest form of your martial soul should be 'eyes,' an extremely rare and powerful eye-type martial soul. Am I correct in my judgment?"

Ling Yu pondered for a moment.

His source of power is certainly not the "Martial Soul" of this world, but as the Sharingan is the most prominent external feature and the window for projecting power, it is not unreasonable to understand it in this way.

He chose a neutral answer: "When I use my ability, my eyes do indeed undergo noticeable changes."

Wang Yan nodded thoughtfully, seemingly memorizing this point. "Indeed. In the existing theory of Body Spirits, the eyes are considered top-tier, most closely connected to the brain and mental perception. Therefore, the vast majority of top-tier eye-type Body Spirits have abilities highly concentrated on the mental level—extraordinary vision, motion capture, mental penetration, illusion construction, thought interference, and so on."

He looked at Ling Yu, his tone certain: "The invisible influence that initially slowed down Teacher Zhou Yi's movements and even caused her to momentarily lose her senses during your battle today should be a manifestation of this kind of mental attribute ability, right? It's very subtle and powerful. Even a Soul Emperor-level expert would find it difficult to be completely immune if caught off guard."

"It can be considered some applications on a spiritual level," Ling Yu admitted.

The essence of Sharingan's genjutsu is indeed a high-level application of mental power.

"That's exactly what the theory can explain." Wang Yan changed the subject, tapping his knee unconsciously with his fingers, revealing his inner turmoil. "However, the abilities you subsequently demonstrated completely exceeded this explanatory framework."

He raised his hand and began to list them one by one, his tone becoming increasingly confused, yet also increasingly excited: "First, the earthen wall defense that rises instantly from the ground with a stable structure. This requires an extremely strong affinity and precise control over the earth element, or rather, the earth attribute of soul power. It is a typical elemental attribute ability, with very little connection to the spiritual attribute."

"Secondly, your body erupts with silver-white lightning, greatly enhancing your speed, strength, and reaction time, and forming a lightning shield around your body. This is a high-level amplification and energy release of pure lightning-attribute soul power on your physical functions, which is also quite different from the development direction of the spiritual attribute."

"Thirdly, and this is the most puzzling point for me," Wang Yan's gaze sharpened as he stared intently at Ling Yu, "you compressed and condensed lightning energy to an extreme degree, forming that silver-blue light blade with terrifying cutting and penetrating power. This is not just a simple application of lightning attributes, but involves the ultimate transformation of energy form and the high purification of its properties, which requires an extraordinary level of understanding and control over this attribute."

He took a deep breath and summarized, "Mental attribute, earth attribute, lightning attribute. Three attributes, completely opposite, yet they all appear in one person at the same time. And it's not just a superficial understanding, but each one has been cultivated to the pinnacle, enough to confront powerful enemies across borders."

Wang Yan leaned back, his face showing a mixture of confusion, amazement, and intense curiosity. He shrugged and said, "Ling Yu, this completely violates the fundamental principles of Soul Master development. In my theoretical system, a Soul Master's Martial Soul should have a relatively pure and stable attribute base. Forcibly absorbing Soul Rings that don't match one's own attributes or have overly mixed attributes will cause the Soul Power system to become disordered, the power of skills to hinder each other, cultivation to be twice as difficult and half as effective, potential to be exhausted early, and in severe cases, even damage to the Martial Soul, cutting off one's future path. This is an ironclad rule verified by countless cases."

He leaned forward, his gaze intense: "But you, Ling Yu, you're like a living paradox. Theoretically, with your 'chaotic' way of adding abilities, your martial soul should have developed serious problems long ago, and you couldn't possibly have achieved what you have today. But the fact is, not only did you not have any problems, but you became so powerful that you defeated Teacher Zhou Yi head-on with only a three-ring cultivation level. This... this completely overturns many of the basic theories I know. Can you understand my confusion?"

Ling Yu listened quietly to Wang Yan's long and passionate analysis.

He knew perfectly well that Wang Yan's theory itself was not wrong, but his understanding was flawed—his power system was not the same as the martial soul and soul ring system of this world.

The nature transformation of chakra, the spiritual power of the Sharingan, and techniques like Chidori/Raikiri that combine nature transformation and form transformation to the extreme have their own cultivation logic and energy foundation in the ninja world, and are completely unrelated to the spirit ring attachment rules in Douluo Continent.

But of course he couldn't explain it that way.

He paused for a moment, seemingly considering how to respond to this eager-to-learn theoretical researcher.

At the same time, he also became curious and curious about the nature of his own power. He wondered if he could grasp the nature of his power and make "Akatsuki" even stronger.

Ultimately, he chose things that were easy to talk about and understand.

"Teacher Wang," Ling Yu began slowly, his voice steady, "I don't know much about the essence of martial souls and the additional rules of soul rings, so I can't comment on your theories. But I can share some of my own experiences in the application of power."

Wang Yan immediately sat up straight, concentrating intently, like a student waiting for the mystery to be solved.
