Starting as a Grandmaster, all of my cultivation techniques are at max level.

Xia Jin's pupils contracted slightly as she stared intently at the changes occurring on Hei Tu's body.

"Interesting." He flicked his wrist, and the longsword emitted a crisp hum. "Then let's see how tough your new body is!"

He took a step forward and slashed his long sword down.

"The Three Swords of Avici Hell—Severing Karma!"

A flash of crimson light appeared, instantly slashing towards Hei Tu's face!

Black Butcher grinned, then stretched out his giant, fan-like hand and grabbed suddenly!

He actually managed to grasp the crimson blade light in his palm, causing it to explode into countless points of light!

"The first cut is just a tickle!" Black Butcher laughed wildly.

Xia Jin's gaze remained unchanged as she swung her blade a second time.

"Sever ties with the mortal world!"

A fierce glint flashed in Black Butcher's eyes. He thrust out both fists, crossed them in front of his chest, and charged headlong into the blade!

"Bang!"

The blade shattered, and a faint white mark was finally left on Hei Tu's iron-like arms, but that was all.

"The second strike, that's getting interesting!" Black Butcher spat, "but still not enough!"

"Is that so? Then try my third strike." Xia Jin raised the long sword high above his head, and a hellish aura spread out, as if countless vengeful spirits were wailing on the blade!

"Hell...Break!!!"

The third strike was unleashed with all its might! The blade light transformed into a thin line, tearing a rift in space that would never heal!

This strike finally made Black Butcher's maniacal laughter subside, revealing a hint of seriousness.

He let out a low roar, no longer being arrogant. The muscles in his arms bulged out like writhing dragons, crossing and blocking in front of him, and a layer of metallic black luster shone on his arms!

"clang--!!!!"

The impact was so powerful that it created a ring-shaped explosion, completely tearing apart the clouds even higher up!

The flashes of light dissipated.

The void beneath Hei Tu's feet exploded, sending him sliding dozens of feet backward before he regained his footing.

He looked down and saw a clear red mark on the outside of each forearm, with a faint stinging pain.

"Excellent swordsmanship!" Black Butcher flicked his arm, the red mark quickly fading. He looked up, his eyes burning with fighting spirit. "It actually managed to injure my 'demon body'! But still not enough!"

He extended his thick finger, beckoned to Xia Jin, and sneered, "Kid, anything more exciting? Let me have my fill!"

Xia Jin narrowed her eyes slightly as she looked at the rapidly disappearing red mark on his arm.

The strength of the opponent's physical body was indeed terrifyingly beyond his expectations. Apart from that black dragon, this person was probably the strongest he had ever seen in terms of physical strength alone.

"Not exciting enough, huh?" Xia Jin suddenly laughed. "Then... as you wish, I'll give you something more exciting to try!!"

As Xia Jin spoke, her eyes turned blood red!

"Demon Heart Crossing!!"

His black hair danced wildly, and the aura emanating from him was far more powerful than before.

"This kid!!" The old man Mo Ya, who had been watching from the sidelines, suddenly changed his expression, a look of disbelief appearing on his face for the first time. "This aura... could it also be a top-tier demonic art?! He... could he be one of us?!"

A sharp glint flashed in Bai Luan's eyes as she stared intently at Xia Jin, whose aura was shifting. After a long while, she shook her head: "No, she's different from us!"

Black Butcher was taken aback at first, then burst into wild laughter, completely without any fear: "Hahahaha!! Good! Excellent! This is more like it! Kid, so you're not exactly a saint either! Come on! Show me your strength! Let's see if I can withstand your blade!"

He excitedly pounded his chest, making muffled thuds, as if to provoke Xia Jin.

Facing the extremely arrogant Black Butcher, Xia Jin's lips curled up slightly: "Then you'd better... hold on, don't die so easily."

As soon as he finished speaking, his figure suddenly became blurry.

The next moment, the blade flashed!

"Seven Forms of Terrifying Silence!"

Black Butcher's pupils contracted. He didn't have time to completely dodge. The blade grazed his shoulder, and a bloody gash appeared directly on his indestructible demonic body.

"What?!" Black Butcher was shocked and furious, and even became more excited.

However, before he could react, several more stabs followed!

Each strike is faster and stronger than the last!

With the blessing of "Demon Heart Crossing", Xia Jin's every strike exceeded Hei Tu's expectations. The sword intent advanced layer by layer, and the power increased exponentially!

Hei Tu went from initially trying to block the attacks head-on, to barely managing to defend himself, and then to having to dodge and parry. He was forced into a somewhat disheveled state by the relentless, increasingly ruthless sword strikes, and several more wounds, some deep and some shallow, appeared on his body.

When Xia Jin's aura reached its peak, she unleashed that ultimate seventh strike.

The excitement and unrestrained laughter on Hei Tu's face vanished instantly, replaced by horror! He sensed the aura of death from that single strike!

"Don't answer! You'll die if you do!!"

The thought suddenly flashed through his mind. At the crucial moment, he finally decided to avoid it.

A dark blade flashed past his ribs, slicing away a layer of flesh from his incredibly tough demonic body, revealing the metallic-looking bones beneath.

Black Butcher, still shaken, looked at the blade of light that had swept past and silently obliterated a corner of a distant mountain peak, a cold sweat breaking out on his back.

"That was...that was close!" He panted heavily, his gaze towards Xia Jin completely changed. "Kid, you're ruthless! But after taking so many of your moves, now...it's my turn!!"

He roared, spread his arms, and his powerful body began to spin wildly around his feet!

At first, it wasn't very fast, but in the blink of an eye, it turned into a black tornado!

A powerful suction force emanated from the center of the vortex, firmly locking onto Xia Jin and making the space around him viscous and stagnant, making it difficult for him to escape easily!

"Kid, you should be grateful to have died from one of my moves!"

The black tornado hurtled towards Xia Jin! Wherever it passed, space was shattered into countless fragments!

But faced with this terrifying, unavoidable attack, a cold mockery flashed in Xia Jin's blood-red eyes. He slowly sheathed his longsword, raised his hands, and pointed to the sky.

"Hey big oaf, have you... ever been struck by lightning?"

The boundless dark clouds gathered rapidly at a visible speed, covering the entire sky above Yuehua Kyoto!

Within the clouds, blinding lightning bolts darted wildly, and a destructive divine might spread out!

"What?!" Bai Luan and Old Man Mo Ya, who had been watching the battle intently, were both speechless at the same time!

"Thunder magic?! How... how could he possibly master thunder magic?!" Old Man Moya looked at Xia Jin as if he had seen a ghost.

Since becoming one of the "Ten Fierce Generals," he had never seen anyone who could wield such a secret technique as thunder magic.
