After traveling through the world of Demon High School and wandering around in it for a thousand years, when Chen Eliog became the fifth demon king of the underworld, he received an invitation from a dimensional chat girl.

Out of boredom, Chen Eliog chose [Accept].

Cang Yue: Welcome newcomer! I am the strongest fighter among all the girls, let me know!

Esdeath: The person above is talking nonsense! I am the strongest fighter among all the girls, let me know!

Yukinoshita Yukino: Hello newcomer! As an ordinary person, I am trembling between two big guys!

Shinomiya Kaguya: +1!

"…………"

Chen Eliog: "Thank you for the invitation! I am in hell and have just become a demon king: I have official business to attend to, so I will hide for the time being."

[Three-color domineering + mythical beast species + easy daily life + not a saint + no magic change]

PS: Not invincible at the beginning, early training is slow

There are no self-created devil fruits. All mythical beasts are from the original works, games or official activities. There is no magic modification.

After traveling to the world of Fairy Tail, Roger obtained a game system that allows him to sign contracts with specific individuals, granting him and his contracted partner special magic. After signing a contract with Erza, the two of them both gained access to dress-up magic and additional magic. Defeating enemies also drops magical items and skills. The Honesty Pipe: Those enveloped in the smoke can't help but speak their true feelings. The Sadness Onion: Cutting it causes everyone within 10 meters to feel intense sadness and burst into tears. The Big Mouth's Prophecy Crystal Ball: Possess a crystal ball that can see into the past and the future, but beware: this crystal ball is quite gossipy and will accidentally reveal hidden details of the past based on its predictions. As the magic power of the contractor increases, Roger's magic power will also increase. Here you can see but not limited to: Lucy, a melee summoner who has learned the Star Clothes in advance, has sufficient magic power, and can form a team by herself; Mirajane, a demon with unlimited power to devour demons, who welcomes the gate of Hades in her prime; Erza, the swordsman who can drop armor and weapons when defeating enemies and has learned enchantment magic; Natsu who has the Burning Decree and has learned the God-Slaying Magic; and Roger, the almighty Magic King and the guild president who secretly controls the Council.

In Zoroastrianism, the mother of evil is the source of all evil and darkness!

It is said that she created the six demons of "malice", "chaos", "aging", "betrayal", "weakness" and "destruction"!

Saigo, who obtained the spirit of the 'mother of evil' in the box garden, became the 'supreme master' in Overlord;

Looking at the 'ruler of death', 'witch of the gap', 'demon of Teyvat', 'big demon of Gensokyo', 'demon of dxd', 'creator of the demon pillar' and others around him;

Saigo is sure that he has established the name of 'evil god';

In this case, he wants to shout out at the top of his lungs - God is dead!

He travels to Konoha and becomes the sole heir of the Senju clan!

In order to revive the Senju clan, Senju Yosei decisively decided to marry Uzumaki Kushina and embark on the path of 'prospering the clan with many children'!

[Thousand Hands Clan Member 1: Awakened Talent. Ishtar Battle Spirit, the host has obtained 'Awakening. Elemental Holy Spirit']

[Senju Clan Member 2: Awakening Talent - Celestial Heroic Spirit, Host obtains 'Legendary Noble Phantasm - The Spear That Shines at the End']

[Thousand Hand Clan Member 3: Awakening Talent. Sun God Nika, the host obtains 'Summoning Beast. Ra's Winged Dragon of Ra']

[Thousand Hands Clan 4: Awakened Talent - Time Spirit, Host obtains 'Kabbalah Tree of Life Fruit']

"Yo yo yo, aren't these the Uchiha clan and the Otsutsuki clan?"

"You've gotten so slender in just a few days?"

After traveling to the pirate world, you still think about just lying down and living your life. Can you have some ambition?!

Adolf D. York, a time traveler without a system, obtained the Superman Happy Fruit by making a wish.

"I have only two biggest wishes in this life!"

"First, wake up and take power over the world!"

"The second one, drunkenly lying on the lap of a beauty!"

“Whether I can do it or not is not known yet, but I will definitely do it!”

"As for dying, I deserve it. I don't have the ability to do that!"

"And the first step to realize my dream! I choose to join the Rocks Pirates to learn advanced experience!"

………………

Many years later.

Adolf D. York sits on the high throne of the Holy Land of Mary Geoise.

Standing around him were countless beauties in maid outfits, including Im, Nami, Robin, and the Empress, and in front of him were reporters from all over the world.

Facing the camera, he said: "Everyone must have dreams. What if they really come true? I am the best example!"

Sitting down in the Internet cafe, he came to a world full of zombies.

But he found girls from other worlds.

Li Ke thought he would spend the rest of his life in this haunted world, but he unexpectedly found that he could go to other worlds through these girls, go to their worlds to save the world, or collect resources.

It's just that the method of passing through is a bit difficult to talk about... But it doesn't matter, as the savior of the infinite world, you have privileges!

A novel revolving around being transported to another world with an op system. The mc spends his day chasing skirts and doing missions to level up. A standard journey to the top with lots of girls from various animes and games with a twist of that gaming feel (hunting mobs, doing missions).

Having only activated his cheat ability two years after transmigrating to the One Piece world, the miserable bounty hunter Norton tearfully began to replan his life. "You touched the corpse of the pirate Shimiru, [Constitution +1]." "You touched the corpse of the fishman Ayok, gaining [Fishman Constitution]." "You touched the corpse of the giant Barbara, gaining the giant swordsmanship skill [Overlord]." From then on, Norton's interest in corpses burned wildly…

Body enhancements are available: Eye of Precognition, Body of Succubus, etc.) Hanyu Kusunoki accidentally came to the world of Death God Elementary School Students. From then on, Conan's demon came. Conan: Why is this bread printed with books, and you can remember it forever if you eat it. Hanyu Kusunoki: Because this is science. Conan: Then what the hell is this protective shield ball? The world has developed science to this point without my knowledge? Hanyu Kusunoki: So this is "science"! Mrs. Yukiko, you don't want to... Hanyu Kusunoki doesn't care about anything
