one piece: gene extraction and fusion system-Chapter 247: The Cursed Sword’s New Form

"You are stopping us because of the Seven Star Sword?" Mio asked calmly.

Hearing this, the witch's eyes widened in shock. She quickly covered her mouth and exclaimed, "Are you here for the Seven Star Sword? No, no, that sword is cursed. If you obtain it, you'll be controlled by it, and it will bring great disaster!"

"We are indeed here for the Seven Star Sword," Mio replied without any sign of concern. "But being controlled by a sword? That's not possible."

With that, Mio turned and walked directly into the castle, uninterested in further debate.

The witch tried to rush forward to stop him, but before she could make a move, Erica turned her head slightly. A fierce aura burst forth from her body, washing over the area like a crashing wave. The pressure was so immense that the witch's eyes rolled back, and she collapsed to the ground, unconscious.

Without pause, the group followed Mio deeper into the castle.

They ascended the stairway and arrived at a large room. Mio's eyes lit up as soon as he entered. His gaze landed on a sarcophagus placed at the center.

Erica, holding an ant between her fingers, looked toward the sarcophagus and said, "This is it. The ants mentioned something inside that emits a terrifying presence. They're scared of it." freёnovelkiss.com

"It's definitely not normal," Bai Feng added, his tone serious. "There's a murderous aura coming from it that's strong enough to be sensed clearly."

Mio smirked. "Interesting."

With no hesitation, he kicked the sarcophagus open. Inside lay a sword—a long blade that shimmered like it was forged from gemstones. It was the Seven Star Sword.

Though luxurious in appearance, the sword radiated a murderous aura so potent it seemed almost alive—an intentional warning to anyone who dared approach.

Mio reached for the hilt without fear. The moment his fingers touched it, the sword began to tremble violently. A wave of strange energy surged into his mind, attempting to corrode his will and control his body.

"So it really can affect the mind... But if this is the extent of its power, I'm disappointed," Mio murmured.

With a single thought, he shattered the invading force with overwhelming mental pressure. The sword quivered in response, emitting an even denser murderous aura. A strange and seductive energy flowed from the blade, blanketing the room.

Lilith stepped back, pulling Robin with her. "Don't touch that aura," she warned. "It will amplify your killing intent beyond reason."

Even without direct contact, Lilith could feel a faint increase in her own bloodlust. The sword's aura clearly had an influence on emotions, though not enough to control strong-willed individuals like her. Robin, however, might not be so lucky.

"Sir, aside from its mental manipulation and being a high-quality weapon, this sword doesn't seem too special," Erica remarked. "Your Raikiri isn't weaker than this."

"That might not be true," Mio said, his eyes gleaming with interest.

The strange aura began to wrap around him. As Lilith had said, it amplified the urge to kill, but Mio's willpower was more than sufficient to suppress it.

Then something else happened. While Mio held the sword, a unique scene unfolded before him—one only he could see.

[Do you want to cultivate this creature?]

The prompt appeared in the system interface, exciting Mio. This confirmed the Seven Star Sword was a cultivable entity.

So the trip to this island hadn't been a waste after all.

As he gripped the sword tighter, it trembled violently. A sinister blue aura emerged, condensing into a dragon-shaped head that lunged toward Mio's own.

"Get out."

Mio frowned slightly and let out a low, cold growl. A burst of pure spiritual pressure erupted from his body, crushing the dragon head aura into nothingness.

Wasting no time, Mio placed the Seven Star Sword into the cultivation tank.

This sword was indeed extraordinary. Beyond its sharpness and mental manipulation abilities, it had absorbed so much blood and resentment over the years that it could manifest energy into physical forms—like the dragon head that had just attacked him.

That alone made it more valuable than most weapons.

"I just hope you won't disappoint me," Mio muttered, turning away from the tank.

As he walked, he selected various genes to merge with the sword during its cultivation.

First were several beast genes.

Then he added more powerful genes: the Samehada genes. Grim Reaper genes. And lastly...

Nephila Bride genes.

The Nephila Bride was a myth rooted in ghost stories—a cursed spirit. The Seven Star Sword was no different. It, too, was a demonic entity.

That made the Nephila gene the perfect match.

Mio smiled with growing anticipation, eager to see what would emerge from this fusion.

"Let's go," he said to the group, beginning the cultivation process.

The disappearance of the Seven Star Sword didn't surprise Erica or the others. They all knew Mio possessed strange abilities. Even Robin, now somewhat accustomed to the bizarre, didn't question it.

Outside the castle, the witch remained unconscious on the ground.

Meanwhile, just beyond the castle gates...

A massive gathering of ants had assembled, forming a neat path. At the end of this path, a Devil Fruit was carried atop the ants and delivered to Mio.

Erica picked it up and handed it to him.

Mio examined the fruit, curiosity sparking in his eyes. "I've never seen this fruit before. It's not in the Devil Fruit Encyclopedia. Could it be... an undiscovered Devil Fruit?"

That possibility made Mio hesitate.

If he used it for a system lottery, he risked losing a potentially powerful ability. But if he gave it to someone else, that chance might be wasted entirely.

"Forget it. I'll hold onto it for now," Mio sighed, sounding a little reluctant.

He turned to Lilith. "Wake the girl."

"Yes, sir." Lilith smiled and gently shook the witch awake.

As she opened her eyes, the witch clutched her head and quickly remembered what had happened. Her eyes snapped to Mio in panic.

"You—you can't go in there! No matter how powerful you are, the sword will control you!"

"No need to worry," Mio said as he walked away. "We've already been in. In fact, you might want to thank me—I've resolved the problem with the sword. The Seven Star Sword will no longer appear in this world."

At least, not in the same form.

Just then, a new prompt appeared in front of Mio:

[Please choose the training direction: Beast-type or Human-type?]

"Human-type," Mio answered immediately.

As he made his selection, his excitement only grew stronger.
