Douluo Continent: Thunder Roar

After seeing off the reluctant Jiang Nannan, Ling Yu began to reflect on himself and plan his next training session.

Before setting off for Shrek Academy, he made a special trip through the Star Dou Great Forest to obtain his third spirit ring.

Now, his first martial soul, "Ninja," has three soul rings.

His first spirit ring granted him a vast knowledge system of "Yin Release" and related ninjutsu, covering many secret techniques such as illusion, mind manipulation, and even shadow control.

Non-attribute ninjutsu can be released without the need for soul ring conversion, such as sealing techniques and basic ninjutsu. This information appeared in his mind after he obtained his first soul ring and activated his martial soul.

In the past two years, he has mastered some basic illusion techniques and several practical mental techniques, including sealing techniques.

The second spirit ring corresponds to "Yang Release," the core of which is the power of life and creation, and its most direct manifestation is medical ninjutsu.

This is the foundation that supported him in opening "Huichun Hall" in Lingdou City.

Through continuous practice, he has become proficient in using intermediate medical ninjutsu such as Palm Healing Technique, and has gained theoretical knowledge and practical experience in more advanced cell-level healing techniques.

The third ring he has now acquired grants him the five elements attributes and corresponding ninjutsu training methods.

Fortunately, Ling Yu did not start from scratch.

After transmigrating, his original chakra was transformed into the soul power of this world, which he could use to unleash ninjutsu.

Before his transmigration, he was a Chunin of the Uchiha clan. Having experienced the trials of the Third Shinobi World War, he was most skilled in Fire Release and Earth Release. He had a deep understanding of the nature transformations of these two attributes and could quickly master their conversion and application.

Even without deliberate practice, they can easily use the ninjutsu they already know from these two attributes.

Because Volibear, an ancient demigod who controls storms, resides within Ling Yu, the "storm authority" originating from his very being grants him an extraordinary affinity and talent for controlling the attributes of "wind" and "thunder."

It's as if he was born with the chakra of wind and lightning, so there's no need for nature conversion.

Furthermore, inheriting Volibear's Storm Domination talent makes mastering these two attributes of ninjutsu much easier and simpler.

"Lightning Release..." Ling Yu pondered, several renowned Lightning Release ninjutsu from his previous life flashing through his mind. "There is one technique that combines extreme penetrating power and speed. Whether it's for surprise attacks, breaking through defenses, or developing subsequent form changes, it has great potential... and it's a perfect match for my Sharingan."

The dormitory was clearly not the place to test such a high-risk ninjutsu technique.

Ling Yu quietly left the academy and found a secluded, deserted gravel valley on the western outskirts of Shrek City.

Stand still, concentrate, and form a mudra with your hands.

Ugly - Mao - Shen

He slowly raised his right hand, his five fingers slightly spread, and focused his mind on manipulating the lightning-attribute soul power. The lightning-attribute soul power responded exceptionally quickly, almost surging and converging into his palm the moment he thought of it.

The initial attempts did not go smoothly.

The raging lightning energy surged wildly in his palm, difficult to control. The resulting ball of light was loosely structured, with arcs of electricity scattering haphazardly and emitting chaotic, ear-piercing hissing sounds. It resembled a dangerous ball of electricity that could explode at any moment, rather than the condensed, tangible, piercing blade he remembered.

Ling Yu was not discouraged. He dispersed his energy and closed his eyes to recall.

He combined the subtle insights of his Sharingan to adjust the rhythm and intensity of his soul power output, as if taming a group of wild but naturally close elves.

After several adjustments, the situation began to change.

The lightning in his palm gradually receded, and the blinding white light no longer spread erratically, but was forcibly gathered and compressed.

The sharp, piercing sound of lightning friction, which was initially chaotic, became clear and focused, eventually transforming into a stable and penetrating high-frequency noise.

Suddenly, the valley was filled with the sound of a thousand birds singing.

It worked!

Although he was still far from perfect control and maintaining the form was somewhat difficult, the prototype of "Chidori" had already emerged in his palm.

The raging lightning was confined to a small area in front of his palm, condensing into a highly compressed ball of brilliant lightning that constantly burst forth with fine arcs of electricity, exuding a terrifying aura of destruction.

Ling Yu dissipated the lightning in his hand, feeling his heartbeat quicken slightly and his soul power being depleted. A look of satisfaction flashed in his eyes.

This proves that his thinking was correct; he has enormous potential for development and a very high starting point in lightning techniques.

After several more attempts, I became more and more adept at releasing Chidori.

"Next, let's try another application."

Ling Yu thought of "Rising Thunder" from the four soul skills of the Undying Thunder Martial Soul, which was awakened after Volibear sacrificed himself to him.

This soul skill is similar to the Lightning Release Chakra Mode of the Cloud Shadow in Naruto.

The principle behind all of these is to use lightning-attribute chakra to fully stimulate and activate the body's cells, thereby significantly increasing nerve conduction speed, muscle contraction strength, and overall reaction ability in a short period of time, resulting in amazing speed and defense enhancements.

If this ninjutsu were developed, it would be an extremely powerful combat method, whether combined with Lightning Blade, taijutsu, or the Raikage's One-Piece Piercing Hand.

He acted immediately upon thinking of it, mobilizing his soul power once again. This time, he was even more careful to guide the small amount of lightning-attribute soul power, which was precisely controlled, to his limbs and bones like a trickle.

A tingling, slightly painful sensation instantly spread throughout the body, as if countless tiny electric currents were coursing through the skin. The muscle fibers trembled slightly, filled with a power ready to be unleashed, and the five senses seemed to have been wiped clean, becoming clearer and more acute.

He tried to take a step forward.

"Whoosh!"

The figure rushed forward several meters in an instant, far exceeding its usual stride and speed, leaving only a faint afterimage and a few lingering arcs of electricity in place.

"The effect is remarkable." Ling Yu stopped and carefully felt the state of his body.

This comprehensive activation and enhancement provides immediate and significant assistance in combat.

However, this is only the most basic stimulation at present, with limited duration and intensity, and it consumes a lot of soul power and puts a considerable burden on the body. It requires long-term practice to optimize the soul power output mode and enhance the body's adaptability.

"The 'Chidori,' which combines attack and speed, and the 'Lightning Release Activation,' which fully enhances oneself... With these two as the foundation, the practical combat system of Lightning Release has taken shape." Ling Yu planned in his mind, "What needs to be done next is to develop the form changes of Chidori, and to deepen and normalize Lightning Release Activation."

In this deserted valley, he repeatedly practiced the "Chidori" and "Lightning Release Activation" techniques he had just mastered, getting familiar with the sensations brought by these two new powers, and constantly fine-tuning the path and intensity of his soul power circulation.

As the sky began to lighten again, Ling Yu finally stopped his cultivation, which had lasted for a day and a night.

He was soaked in sweat, his clothes had many scorch marks from the out-of-control lightning, and his face showed exhaustion, but his eyes were surprisingly bright.

Ling Yu slowly exhaled a breath of stale air, his eyes shining brightly.

The training overnight yielded remarkable results, and he also mastered several practical Wind Release ninjutsu.

However, apart from Wind Release: Rasengan, there is not much prospect for development in Wind Release for the time being. Before mastering cell activity enhancement and achieving at least Tsunade's level of recovery ability, he does not plan to spend more energy on Wind Release.

When I got back to the dormitory, it was already dawn.

Ling Yu quickly washed up, changed into clean clothes, and his face didn't show much fatigue; instead, he had a spirited and energetic air about him.

"Click~"

A faint, clear sound of a key turning came from the lock on the dormitory door.

Ling Yu looked up at the door.

At that moment, the person who had the other key to this dormitory room... arrived.

The door was slowly pushed open.

The first thing that catches the eye is the visitor's unique, striking pinkish-blue short hair, which stands out particularly in the light of the corridor outside the door. The hair is neat and tidy.

The newcomer was tall and upright, dressed in a well-fitting casual outfit, yet exuding a refined air that was not typical of boys.

Ling Yu raised his gaze and it fell on the other person's face.

It was an extremely handsome face, one that could even be described as beautiful.

Her skin was fair and delicate, and every line of her facial features seemed to have been meticulously sculpted, combining to present a breathtaking perfection.

In particular, her large, clear, and bright pinkish-blue eyes, with slightly upturned corners, were scanning the room with a hint of curiosity and observation, as if she were entering an unfamiliar environment for the first time.

But when Ling Yu met her gaze, her beautiful eyes widened almost imperceptibly for a moment, a clear hint of surprise flashing across them.

Wang Dong'er was indeed somewhat surprised.

Her ideal roommate might be honest and simple, or arrogant and domineering, or timid and ordinary... but definitely not like the one in front of her.

This boy, just sitting there quietly, exuded an indescribable aura.

His face was handsome, still carrying a hint of youthful spirit, but his brows held a calmness and composure far beyond his years.

What caught Wang Dong'er's attention most were his eyes as he looked at her. They were dark and clear, with a steady and focused gaze. There was no awkwardness as if they were meeting for the first time, nor any amazement at her stunning appearance. Instead, they were like a deep pool, calm and undisturbed.

What struck her as even more astonishing was the energy and spirit emanating from the other person—full, restrained, yet subtly sharp, confident, and fulfilled.

This was unlike any new image she had envisioned.

However, this surprise lasted for less than a second.

Wang Dong'er quickly composed herself, her delicate chin tilting slightly as she habitually raised it, and the curiosity in her pink-blue eyes was replaced by a deliberately crafted aloofness and pride.

She gently closed the door, as if to shut out the outside world, fully displaying the aloof demeanor of the "Young Master of Haotian Sect" in this small dormitory space.
