The Hehuan Sect cultivates alchemy; my senior sister helps me refine alchemy throughout the world.

Hades snorted coldly, and the bone dragon spread its wings, sending a cloud of dark, ghostly energy rushing towards them.

Shen Yifei swung his Long Sky Sword horizontally, unleashing the Breaking Army Sword Style. The sword light pulsed, cleaving through the black mist, and with unstoppable momentum, slashed straight at the Underworld King.

Hades didn't move an inch. He simply raised one hand and casually blocked it.

Shen Yifei's sword light struck the black energy in Hades' palm, as if it were cutting into a ball of cotton, becoming more and more ethereal the further it went, until it finally dissipated into nothingness.

Hades's spirit-slaying blade slashed down with the momentum.

Before the blade even arrived, the wind from it carved a deep trench in the ground. Shen Yifei met it with the Rifting River Sword Style, his sword flowing like a long river, deflecting the blade's momentum layer by layer.

But Hades's blade was too heavy; each strike felt like a mountain pressing down. Shen Yifei took seven blows, his hands went numb, and he nearly dropped the Long Sky Sword.

Hades sheathed his sword, his voice tinged with disdain: "What a pity, the successor of the Five Elements Demon God can't even withstand fifty percent of my power?"

Shen Yifei's Long Heaven Sword was stuck in front of him, a gash in his hand, and blood from his soul flowed down the hilt. He looked up at the King of the Underworld and suddenly smiled.

"You can still laugh even when you're about to die? Don't worry, I'll leave you a whole corpse. I still need your body!" Hades sneered.

"Use my body, and you'll have to use all your strength." Shen Yifei slowly raised the Changtian Sword.

He held the Long Sky Sword in his hand, horizontally in front of him.

Po Jun, using overwhelming force, has already been used; Lie Chuan, continuous and unbroken, has also been used. Neither of these two swords could stop Hades' blade.

All that's left is the void.

Returning to the Void, there is no turning back!

Shen Yifei closed his eyes, and the small vortex in his dantian began to spin wildly. The five elements of magic power surged into the sword like a river bursting its banks.

At the same time, the cursed power that had merged into the small vortex also stirred. Like a newly tamed wild beast, it willingly released its power for the first time.

The two streams of energy intertwined on the Changtian Sword, forming two swirling currents.

"Hades." Shen Yifei opened his eyes. "Remember this sword of mine. It is called Guixu. Once you go, you will never return."

"Hahaha, alright, I'll take your move. I'll make sure you don't leave alive!"

Hades didn't take him seriously at all; in his eyes, Shen Yifei was just a mouse toyed with.

Shen Yifei practiced the "Return to the Void" sword technique for three days and finally grasped its essence.

No defense, no retreat, no room for maneuver!

He walked to a distance of ten feet from Hades, who just watched him quietly, completely unconcerned!

Shen Yifei flicked his sword tip! There was nothing fancy about it.

Hades immediately sensed a sword intent he had never encountered before!

At the same time, he also felt the chill of death.

This was a feeling he had never experienced in his millions of years!

For the first time, he felt fear!

Hades dared not be arrogant any longer and charged forward with his sword.

He used all his strength in this strike. With one strike, all the yin energy within a hundred miles was absorbed into the blade. Before the blade even arrived, the ground was pressed down and collapsed three feet.

Shen Yifei's sword pierced through the blade's edge and layer upon layer of Yin energy. The moment the sword's edge met the Spirit-Slaying Blade, only a very soft and faint "ding" was heard.

Hades was taken aback.

In that brief moment of hesitation, the tip of the Long Sky Sword had already pierced his chest.

Three inches.

Hades looked down at the sword at his chest. By the time he realized what was happening, Shen Yifei had already drawn his sword and taken another step forward.

The second sword strike was the same move.

The Hades' Spirit-Slaying Blade slashed back, but Shen Yifei didn't dodge. His second sword thrust directly towards the Hades' throat.

Hades tilted his head, and the sword's edge grazed his neck, taking away a piece of flesh.

The third sword strike.

Hades's Spirit-Slaying Blade slashed fiercely towards Shen Yifei's shoulder. If this strike landed, half of Shen Yifei's body would be cleaved away. But Shen Yifei didn't even try to block; the third sword pierced straight into Hades's abdomen.

At the same time, Hades's sword also struck.

The moment the blade touched Shen Yifei's shoulder, the curse power within Shen Yifei's body surged out on its own, forming a thin gray shield. Then, the earth spirit added another layer of protection outside the shield!

However, Hades dared not use too much force, lest he destroy the body and become unusable himself!

Even so, Shen Yifei was still not feeling well.

Although the protective shield blocked most of the force, the blade's edge still sent Shen Yifei flying.

Although the protective shield blocked most of the force, the blade's edge still sent Shen Yifei flying.

He rolled seven or eight times on the ground, a deep wound on his shoulder that exposed bone, from which blood gushed out.

Xinghe, inside the Cauldron of Myriad Things, hurriedly treated Shen Yifei's injuries.

Hades was dumbfounded; his strength had only managed to injure the boy's skin and flesh.

Shen Yifei stood up with a chuckle: "How's my fighting style? Life for life, you dare?"

In fact, Shen Yifei was certain that Hades wouldn't dare to fight him to the death. Firstly, Hades was Hades, whose status was far superior to his own; secondly, Hades desperately needed his body to cultivate that so-called immortality technique.

Hades stared at the wound on Shen Yifei's shoulder. Seeing the wound healing rapidly, his unease grew stronger.

What kind of monster is this kid? Shi Yan only said that he was the successor of the Five Elements Demon God, and that his Five Elements Demonic Power body could bear the immortal technique, but he didn't say that this kid would have such a strange technique!

Hades dared not be careless again. He brandished the Spirit-Slaying Blade, his entire body surging with black energy. This time, he held nothing back, pouring all his Netherworld power into the blade.

"Shen Yifei! I'd like to see how many more of my knives you can withstand!"

The blade's edge flashed like a bolt of lightning, instantly slicing through the sky, and the ground cracked wherever it passed.

Shen Yifei did not retreat a single step; the Long Sky Sword continued to thrust forward. With this strike, he unleashed all the power within his body.

The five elements of magic, the power of curses, and especially something strange that surged into his mind—he could feel it, and it smelled a bit foul!

However, after this foul-smelling power was combined with the Five Elements Magic and the power of the curse, its combat power increased exponentially!

Hades sensed an unprecedented crisis, a threat he had never faced even when confronting the Celestial Emperor.

He wanted to back away, but it was too late.

Shen Yifei's sword pierced through all his defenses and went straight into his dantian!

Hades' body trembled as he looked down at the longsword embedded in his dantian. The power of the curse was surging wildly into his body through the sword's tip, greedily devouring his billions of years of Netherworld essence.

"No..." Hades roared, "This is impossible!"

Shen Yifei gasped for breath, "Hades, I've destroyed your dantian, what do you have left to fight me with?"

Hades' dantian was pierced by a sword, and the power of the curse continued to devour his essence, while the black aura on his body was rapidly dissipating.

Hades lowered his head and looked at the long sword that had pierced through his dantian. He never imagined that he would be beaten so badly one day!

He was too careless. All he wanted was a body with all five elements of magic to achieve his immortality!

What he wants is immortality!!

Since we can't live forever, let's die together!

"Shen Yifei...you think you've won?"

Hades straightened his body, a hint of madness flashing in his eyes.

Shen Yifei cried out inwardly, "This is bad!"

But it was too late!

Hades clasped his hands together, and a blinding black light erupted from his body. His body began to swell, and his underworld power leaked out wildly.

Shen Yifei tried to draw his sword, but he couldn't, and his body was also immobilized!

Just then, Liu Mengli floated out of the Cauldron of Myriad Things!

"Master! Watch out!! Take this!!!"
