One person: Starting with the Snow Drinking Blade

*Sizzle!* A blinding white bolt of lightning surged forth again, but this time, it didn't cover his entire body. Instead, it seemed alive, forming a dense, constantly flowing and leaping armor of lightning on his skin! His hair stood on end, and tiny flashes of electricity flickered in his eyes! His speed, strength, and reaction time increased to an astonishing level in that instant!

"Oh? Compressing lightning magic onto the body surface to form a 'lightning armor' that strengthens oneself? Interesting." A hint of interest flashed in Nie Lingfeng's eyes. This is a way to maximize the auxiliary function of lightning magic. It seems that Zhang Chulan has indeed put in a lot of effort in developing the application of lightning magic.

"Here it comes!" Zhang Chulan roared, and the ground beneath his feet exploded! His figure vanished again, but this time, he didn't rush forward in a straight line. Instead, after leaving a clear afterimage, his true form appeared to Zhang Lingyu's left! His fist, enveloped in blazing white lightning, slammed down! The speed was more than twice as fast as before!

"So fast!" Zhang Lingyu was slightly surprised, but his movements were swift. His feet didn't move, but the black lightning energy around him seemed to come alive, automatically condensing on his left side and transforming into a constantly rotating black vortex!

"Northern Azure Pool - Whirlpool!**"

The white lightning fist slammed into the black vortex, unleashing another violent energy clash! But this time, Zhang Lingyu clearly felt the pressure! The power and penetrating force of the white lightning fist were far stronger than before! The black vortex trembled violently, even showing signs of being torn apart!

"It's not over yet!" Zhang Chulan's voice came from the other side! His figure had reappeared on Zhang Lingyu's right side at some point, and a fierce whip kick, carrying blinding lightning, swept down at her waist! The speed was so fast that it seemed as if he appeared in two directions at the same time!

"Afterimage? No, it's a visual residue left by the excessive speed, combined with the interference created by the lightning technique!" Zhang Lingyu instantly figured out the truth, but her surprise was even greater! Had Zhang Chulan's use of lightning technique reached such a refined level?

He stopped passively defending and his previously steady figure finally moved! With a shift in his footwork, he unleashed a set of exquisite footwork, his body moving like a fish swimming in water, nimbly and slipperily slipping out from the gap between Zhang Chulan's attacks from both sides! At the same time, he formed a hand seal in front of his chest.

"Water Dirt Thunder - All Streams Flow to the River!"

On the training ground, the marks previously eroded by Yin Lightning suddenly glowed with a ghostly black light! Thick streams of black lightning gushed forth from these marks like fountains, instantly weaving into a black lightning net covering a large area, descending upon Zhang Chulan who had just landed! This net appeared sparse, but each stream of lightning carried a powerful corrosive and binding force. Once caught in it, one would likely be instantly invaded by the power of Yin Lightning, becoming unable to move!

"Damn it! Junior Uncle, you cheated! You set up the formation ahead of time!" Zhang Chulan exclaimed, but his face showed no panic. He seemed to have expected it, and the moment the black lightning net enveloped him, his white lightning armor suddenly burst forth with dazzling light!

"Break!"

boom!!!

A violent white lightning bolt erupted from him, spreading wildly outwards like an explosion! The supremely yang and powerful yang lightning collided fiercely with the murky and viscous black lightning net!

"Sizzle—Bang!"

A piercing crackling sound and an explosion rang out simultaneously! White lightning and black liquid lightning violently annihilated each other, producing large amounts of white vapor and a pungent ozone odor! The entire training ground vibrated and hummed from this violent energy shock!

Xu San and Xu Si had already activated the protective barrier around the training ground, but the intense energy fluctuations still caused their expressions to change slightly. Chen Duo silently shielded Xiao Yun behind her, while Xiao Yun's eyes widened with excitement, forgetting to chew the potato chips in her mouth, and she mumbled, "Papa! Black! White! Fighting! It's exciting!"

Nie Lingfeng was also watching the battle intently. Although the two fighters' levels and power couldn't compare to his and the Old Celestial Master's, they were definitely top-tier among their peers! In particular, their understanding and application of the different characteristics of lightning techniques had greatly benefited him. The extreme speed, explosiveness, and brute force of Yang lightning, and the weight, corrosiveness, and softness overcoming hardness of Yin lightning, were all displayed to their fullest extent.

The storm of energy in the arena gradually subsided. Zhang Chulan was panting heavily; his white lightning armor had dimmed considerably, and in some places, it was even torn, revealing his charred clothes underneath. Clearly, forcibly breaking through that net of Yin lightning had taken a heavy toll on him.

Zhang Lingyu, on the other hand, was not in an easy situation either. A corner of his Daoist robe was ripped, and his face was slightly pale. That move, "Hundred Streams Return to the River," had clearly consumed a significant amount of his Qi. However, his eyes remained calm, though a burning fighting spirit flickered deep within them. He realized that fighting Zhang Chulan was completely different from the casual sparring he had with his fellow disciples on the mountain! Zhang Chulan's fighting style was more cunning, more unconventional, and more…effective! He had to concentrate all his energy to cope with the endless variations and attacks!

"Senior Brother Chu Lan, your progress has indeed exceeded my expectations." Zhang Lingyu spoke slowly, his voice still steady, "However, speed and explosiveness alone are not enough to break my 'Northern Azure Pool'."

"Really?" Zhang Chulan wiped the sweat from his face, grinned, revealing a set of white teeth, "Junior Uncle, your Yin Five Thunder is powerful, as thick as a city wall. But... have you ever considered what would happen if I didn't attack the city wall, but instead attacked its 'root'?"

Zhang Lingyu frowned slightly, a sense of foreboding rising in her heart.

Zhang Chulan took a deep breath, and the previously dim white lightning on his body shone brightly again. But this time, it didn't erupt outwards; instead, it flowed towards his right fist like water! His right fist instantly transformed into a small white sun, radiating a heart-palpitating aura! It wasn't a simple compression, but rather the "weaving" and "resonance" of lightning power with a special frequency and structure!

"This is..." Nie Lingfeng's eyes narrowed. He sensed a dangerous aura emanating from that fist! This was definitely not any move that Zhang Chulan had used before!

"Junior Uncle, take this move I created—'Thunderbolt Spiral Bone-Piercing Drill'!" Zhang Chulan shouted, his foot slamming down, and he shot towards Zhang Lingyu like a cannonball! His right fist was in front, and his whole body spun at high speed, forming a spiral of white electric drill! Wherever it passed, the air was torn apart, emitting a shrill shriek!

This move combines the explosive power and speed of Yang Lei with the penetrating power of a spiral, concentrating all the power into one point! It is a killing move that Zhang Chulan specially devised to deal with opponents like Yin Wu Lei, who have thick defenses and are good at using softness to overcome hardness!

Zhang Lingyu's expression finally changed! He could clearly feel the terrifying penetrating power contained in this attack! Although his Yin Five Thunders defense was strong, facing such an extremely concentrated attack, he was afraid...

"Well done!" In this critical moment, a fierce fighting spirit erupted in Zhang Lingyu's eyes! Instead of retreating, he advanced, clasping his hands together in front of his chest, and all the black lightning energy around him converged into his palms like a tide! In the blink of an eye, a black lightning ball, as deep as a black hole and seemingly capable of swallowing all light, condensed and took shape in his palm! The space around the lightning ball slightly distorted, emanating a chilling aura!

"Water-stained Thunder, Deep Abyss and Towering Peak!"

He hurled the black lightning ball, which contained most of his current Qi, outward with a mighty force! There were no dazzling lights or earth-shattering sounds, only an extreme heaviness and profundity, as if it were dragging everything in front of him into a bottomless abyss!

The white spiral drill and the black, swallowing lightning ball collided violently in the center of the training field!

There was no loud noise as I had imagined.

There was only a deep, resonant hum, as if it were sucking your very soul in! White and black were frantically eroding and annihilating each other! The white electric drill spun wildly, trying to penetrate the deep darkness; while the black lightning ball was like a bottomless quagmire, constantly eroding and devouring the violent power of the Yang lightning! The two forces were engaged in the most primal and intense confrontation at a single point!

"Wow... these two kids are serious!" Xu Si couldn't help but click his tongue in amazement. The power of this clash of attacks had already exceeded the scope of ordinary superhumans, approaching the level of some veteran masters!

Nie Lingfeng was also fully focused, his Qi circulating slightly within him, ready to intervene at any moment—if the situation got out of control.

"Click..."

A faint cracking sound rang out. A tiny crack appeared on the surface of the black lightning ball! And the white electric drill was visibly dimming!

Finally, with a reluctant hum, the black lightning ball and the white electric drill exploded simultaneously, turning into black and white lightning that scattered across the sky!

"Pfft!" "Cough!"

Zhang Chulan and Zhang Lingyu simultaneously coughed up blood and staggered backward! Zhang Chulan's lightning armor completely dissipated, his face was pale, and his right hand trembled slightly, the tiger's mouth split open, dripping blood. Zhang Lingyu's Daoist robe was also disheveled, blood trickling from the corner of his mouth, and his breathing was erratic, clearly indicating that he had also suffered serious internal injuries.

Tie!

A draw that resulted in losses for both sides!

The training ground was a scene of utter chaos, with charred marks and corroded pits scattered across the ground. The air was thick with the smell of ozone and burning.

After a brief silence**.

"Hahaha...cough cough..." Zhang Chulan coughed up blood but laughed at the same time, "That felt good! That felt so damn good! Junior Uncle, your Yin Five Thunder is as hard as a tortoise shell!"

Zhang Lingyu wiped the blood from the corner of his mouth, looked at the equally disheveled Zhang Chulan, and a rare, complex smile appeared on his face (though very faint): "Zhang Chulan, your Yang Five Thunders are also incomparably sharp. I barely managed to withstand this move." His tone lacked the usual aloofness and superiority, and contained more of an understanding and...感慨 (gǎnkǎi, a feeling of deep emotion or reflection).

He finally understood why his master had sent him down the mountain, why he had him "train" under Zhang Chulan. Cultivation on the mountain was about refining oneself and building a solid foundation. But the battles down the mountain were life-or-death struggles, seeking breakthroughs at the limits! Zhang Chulan's growth, his unconventional and ruthless fighting style (in combat), and his ingenious use of lightning magic all greatly impacted and inspired Zhang Lingyu.

So, lightning magic can be used in this way.

So this is how battles can be fought.

Nie Lingfeng walked over, examined their injuries, and after confirming that they were only exhausted and had minor internal injuries, he breathed a sigh of relief and smiled, "Not bad, not bad at all. Chu Lan, your last move was a good idea—concentrating your power on one point to break through the surface. It's indeed a good way to deal with a defensive opponent like Ling Yu. However, your control was still a bit lacking, and the backlash was quite significant."

"Lingyu, your Yin Five Thunders technique has a solid foundation, and you're beginning to understand its variations, especially the final move, 'Abyssal Stillness and Majestic Standing Firm,' which maximized the power and devouring potential of Yin Thunders. But..." Nie Lingfeng changed the subject, "your fighting style is still too 'orthodox.' Against an opponent like Chu Lan who doesn't play by the rules, sometimes you need to be more flexible."
