Cheng Mo's life fell into despair.

My younger sister is seriously ill and her studies are on the verge of collapse...

Until he picked up a mysterious compass, his life took an outrageous turn——

Save Nezuko, accept Tanjiro as his apprentice, and get involved in the dispute between the Demon Slayer Corps and Muzan...

"Wait, didn't you agree to just be a profiteer?"

"My Lord, let's discuss business. I'll sell you penicillin, and you'll teach me breathing techniques, how about that?"

"Ms. Tamayo, I have a report on modern genetics. Would you mind using some of my blood to study it?"

"Muzan? Oh, don't run away with that moving gift bag of time and space coins!"

Cheng Mo just wants to resell resources and make enough money to save his sister.

When he looked back, he discovered that he had already held the authority of countless worlds and became the largest behind-the-scenes supplier in the heavens!

Tanjiro: "Teacher, what is the 'currency' of this world?"

Cheng Mo: "It depends. Maybe it's a devil fruit, maybe it's chakra, maybe... the future of a world."

(This book is also known as: "I Resell Supplies in the Heavens" and "After Accepting Tanjiro, I Became the MVP of the Demon Slayer Corps")

One day, many doors suddenly appeared in the world.

At the same time, a power called "Truth" resonates throughout the world.

Someone awakens to the truth of Newton, the father of mechanics, and learns the magic of manipulating gravity to make things fall from the sky.

Someone awakens to the truth of Oppenheimer, the nuclear demon: with a wave of his hand, a city falls into desolation.

Some have awakened to the truth of the banished immortal Li Bai, singing and drinking to admire the snow-covered sword, soaring straight to the heavens to grasp the moon.

Some have awakened to the truth of Azathoth, the god of blindness and folly, and wish to shroud the world in a fog of delusion.

Science, literature, theology... When all the familiar written words become incredible and extraordinary mysteries, where should we, in our ignorance and folly, go?

The player arrived, and so I became the BOSS.

They call me—the Lord of Eternal Night.

Zhang Ye: "Just wait, I will completely expel them from this world, leaving not a single one alive!!!"

Player: "Wait, who provoked him again? Why is he on fire again?!"

Zhang Ye: "Version update, players all log off at midnight? Opportunity!"

Player: "Why is it so dark? Who's playing that BOSS tune over there... Buhao, my guild!"

Zhang Ye: "Want to form a professional team and start a professional competition? Absolutely not!"

Player: "Wait, which pro team got a boss in here?!"

Zhang Ye: "We need someone to hold off the player alliance for ten days? I'll do it!"

Player: "Everyone calm down, listen to me—quickly kill yourself, don't let him have his fun!"

Zhang Ye: "You can't kill me. Death and revenge are on my side. One day, I will return with my might!!!"

Player: "Quick, quick, use all the world items! This is our only chance—nice, we've finally sealed this world boss!"
