On the first day, he laid down the World Tree of the Night Elves and embraced his followers.

OVERLORD fanfic

As a newly returned supreme ruler, Alucard, by chance, traveled to a new world along with Ainz Ooal Gown.

They knew nothing about this completely new world.

How will Alucard, the top player who once dominated "YGGDRASIL", face the problems that follow?

How will Alucard, dubbed the "moving world boss" by his defeated adversaries, survive in this new world?

How can we resolve the conflict between the supposedly invincible True Dragon King and the Sky City left behind by the Eight Desire Kings who ended the Dragon King era?

Let's look at the detailed explanation in the main text.

Lin Xuan, who had just been admitted to university, woke up and found himself in a world where Pokémon and reality merged. Pokémon evolution? What kind of subject is this? Forget it, it has nothing to do with me as a commentator, right? —— —— "Kyogre used Root Wave on Groudon... but missed. That's why skills with low hit rates are a pitfall!" "Now it's Groudon's turn to counterattack. Go up and use Cliff Blade! But Kyogre can fly, so it did cause a minor damage." Just as Lin Xuan was commenting passionately, he found that everyone was looking at him. Everyone: "What the hell are you commentating on?! Why don't you stop these two idiots!!" Lin Xuan had no choice but to take out the Poké Ball and sigh at the two idiots of Hoenn not far away. "Commenting is obviously my job, why do you always want me to fight?"

[Pokémon, Pokémon, Gym Leaders, Play Games to Become Stronger]

Su Ming travels to the elf world and inherits a gym at the beginning, but he will be disqualified from building the gym due to lack of strength.

Just when Su Ming was about to give up and lay down, he discovered that his handheld game could be synchronized with reality!

Since then, a gym leader with a strange style has appeared!

While lying in the gym playing the game, game prompts kept appearing:

[Congratulations on defeating the wild Dragonite and Dodo, gaining a lot of experience and upgrading your Pokémon's level!]

[You use the full-blood resurrection herb, and the elves that have lost their combat ability are restored to their peak state! ]

[Your game treasure hunter has found a treasure, and you have obtained the item Rainbow Feather! ]

[You used the enhanced Master Ball and successfully subdued the mythical beast!]

…

The four kings of the league and the champion were completely stunned:

"Gym Master Su Ming spends all day lying around in the gym playing games. How did he suddenly become invincible?"

At the end of the Eastern Han Dynasty, disasters continued throughout the country, famines occurred greatly, and people ate each other.

Yun Yi accidentally broke into this era.

Fortunately, he has all the characteristics of Steve in my world, and can bring the rules of the MC world into the real world.

Food shortage? MC crops only mature every few days!

Thousands of miles of barren land? Infinite water supply!

Plague breaks out? Don’t worry, milk can cure all diseases!

No place to live? Watch me build a city with my bare hands in one day!

The world is in chaos, with warlords dividing the country?

Have you asked the army behind me wearing enchanted armor?

Hey, why is everyone calling me a god?

But I am just an ordinary cube man!
