I'm a villain with my own world modifier

Bai Qiuyuan: "..."

Bai Qiuyuan looked around and waved his hand to close the editor.

[You can return to the cultivation world or the immortal palace to claim it later.]

"Elvina, tell me about your world."

"Is 'Demon King' a title? Are there other Demon Kings in this world?"

Elvina twisted her boneless Q-version body.

Then he found a comfortable position, sat on Bai Qiuyuan's lap and explained.

"The Demon King is a special profession."

“It is unique. There can only be one in the world.”

"The same goes for the brave."

"However, although there is only one Demon King, there are many [Demon King Candidates] in the world."

Bai Qiuyuan: "Devil King Candidate?"

Elvina: “Yeah.”

"Once the Demon King dies, the Demon King candidates will select the strongest monster from among themselves and make the strongest one the new Demon King."

"Once you become a Demon King, your power will increase significantly in all aspects after inheriting the Demon King's throne."

"In the past, heroes would basically kill all the Demon King candidates whose strength was within the normal range first, gain experience, increase their levels, and become stronger."

"The Demon King was killed last."

"This way, even if we kill the Demon King, no new one will appear immediately."

"Until new Demon King candidates grow up, the position of Demon King will remain vacant for at least a hundred years."

Bai Qiuyuan: "I see."

"After being summoned to this world, can the hero return to his original world?"

Elvina thought for a moment and then replied.

"No."

"But I've heard something about it in fairy tales about demon kings and heroes."

"It is said that after the first generation hero completed his mission, he used his powerful strength to forcibly break through the world barrier and returned to a place called 'Blue Star'."

Bai Qiuyuan: “!”

[Blue Star! Could it be that! The first generation hero is a modern person!]

"If he left his coordinates, wouldn't I be able to use them to return to the present day?!"

{The passive ability of the Tranquility Technique is triggered!}

【…】

[The era in which the first generation of heroes existed has become a fairy tale...]

[Even if the coordinates were left behind, even today, even if they were found, they might not be usable...]

[Although that so-called Blue Planet may not necessarily be the modern world I'm looking for.]

【But... this is at least a good clue. 】

Bai Qiuyuan smiled.

"Just tell everyone that you've taken the hero to another place."

"Help me arrange an identity. I want to stay in the Demon King's Castle for a while."

"Also, don't call me Master anymore."

Elvina: “?”

"What's that called?"

Bai Qiuyuan said with a smile.

"Just call me Bai Qiuyuan!~"

Elvina: “!”

Bai Qiuyuan said with a smile.

"That's all for today. I'm going to take a walk."

"Come back tomorrow."

After saying that, Bai Qiuyuan suddenly disappeared from the throne out of thin air.

Because of her cute appearance, Elvina was slow to react and fell directly onto the throne due to carelessness.

But because Elvina was too resilient, she bounced up directly from the seat after falling on the throne.

Elvina played the piano for several times before stopping.

Elvina was not angry about Bai Qiuyuan's sudden disappearance, but stood there in a daze for a moment.

Elvina: “…”

[Are all the heroes from another world so strong...?]

【Fortunately, I summoned the hero first. 】

[Otherwise, the brave will join the human camp...]

【…】

[The brave man is so handsome...]

With a blush on her face, Elvina took out a "strange book" from "behind" her.

The title of the book is "To capture a man's heart, you must first capture his stomach - Collector's Edition"

……

……

——Immortal Palace——

As soon as Bai Qiuyuan returned to the Immortal Palace, he stretched lazily.

[Even though it was only one day, I still feel so fulfilled.]

Soon, Bai Qiuyuan happened to see the system using wooden swords and puppets to simulate a battle in the square.

It’s not so much a battle as it is because the system is too weak.

So Bai Qiuyuan prepared a motionless puppet for the system.

Although it is a puppet, it is basically no different from an ordinary target.

It hasn't even been strengthened.

System: “Ha!”

The system rushed forward with a sword in hand, raised the sword fiercely and chopped down at the target.

boom!

Target: HP-0.1

Bai Qiuyuan: "..."

System: “Ha!”

After seeing that its attack was weak, the system unwillingly stabbed the target with its sword again!

puff!

Target: HP-0.1

Then, the system outputs another wave!

Then the wooden puppet finally!

I just had some minor skin injuries.

Bai Qiuyuan: "..."

The system held the sword, wiped the sweat from his head with his hand, and smiled at the puppet while panting.

"You... huh... are quite impressive... huh..."

puppet:"……"

Bai Qiuyuan: "..." (covering face)

【At least...she didn't miss just now.】

……

【400】Buy one, get one free

Bai Qiuyuan: "Ahem..."

"System, come here."

system:"?"

After hearing this, the system came to the side and put down the iron sword used for training.

Then he picked up a towel on the table, wiped the sweat off his face and trotted to Bai Qiuyuan.

System: "What's wrong?"

Bai Qiuyuan said with a smile.

"I brought you a gift."

After Bai Qiuyuan finished speaking, he handed a ring to the system.

The system was stunned at first, then its face turned slightly red, and it said excitedly.

[Is this a request? ...]

[Hmm? Wait…]

[Aren't these... the rings Bai Qiuyuan was playing with yesterday?]

[So it wasn't a proposal...]

【No, why should I be disappointed! 】

In the end, the system chose to reach out and take the ring from Bai Qiuyuan's hand.

Bai Qiuyuan explained with a smile.

"This Pandora's ring has the ability to copy other people's superpowers."

"Many abilities have been copied into the ring."

"All abilities can be used directly after putting them on."

"You can familiarize yourself with the ring's abilities here later."

"With this ring, even if you can't defeat others in the future, at least you will have the ability to protect yourself or escape."

system:"!"

【Superpower! 】

Bai Qiuyuan: "The ring in your hand has been specially strengthened by me."

"As long as you complete the blood oath, it will never be lost."

"Even if someone else gets the ring, they won't be able to use the power within it."

After Bai Qiuyuan finished speaking, he handed the system a silver needle.

The system was not pretentious. It took the silver needle and pricked its finger. Then, as Bai Qiuyuan said, it dripped its blood onto the ring.

Soon, the blood was absorbed by the ring.
