Tomodachi no Imouto ga Ore ni Dake Uzai - Volume 4, Prologue

Is magic really a wish machine?

No! In a universe where magic actually exists, the ultimate nature of magic must be as simple and beautiful as the laws of physics.

This is the story of a mass-produced magic warfare tool man who learned the ultimate nature of magic.

But so what?

Just as a bird can fly without understanding aerodynamics, so a wizard does not need to understand the ultimate nature of magic to use magic.

Knowing the ultimate nature of magic does not mean that the tool man can become a great magician.

But the desire for knowledge is human instinct, and curiosity is the first driving force of human civilization. Humans hope to understand the inner workings of magic, even if it is supposed to be unreasonable.

An inquiry into the ultimate nature of magic, without any justification!

The story in the book takes place in an age where steel dances with gunpowder.

Here, muskets are in the ascendant, armor is still the protagonist, military theories are changing with each passing day, and innovations in systems and craftsmanship are emerging one after another. And this world has one more thing than ours: magic.

The world is undergoing earth-shaking changes, and no one can stay out of it.

Lin Mo transmigrated to an eastern fantasy world.

He started off with a classic “zero to hero” opening.

Because of the [God Devourer] special attribute that he was born with, he used up countless resources, yet his cultivation level wouldn’t rise even one bit.

Finally, he was chased out of the clan by the chief.

He became responsible for managing the market place meant for newcomers at Initial Heart Village, which is a small town in the countryside.

He thought that he would live the rest of his life uneventfully as a businessman.

He didn’t expect that he would awaken the [Auction Rebate System]

As long as the auction house sells items, Lin Mo would receive rebates several times the value of the item sold.

[Ding! The host had auctioned off leftover bits from an elixir cauldron. Rebate give: Ninth Level Ultra Elixir: Heaven Forge Restoration Pill!]

[Ding! The host had auctioned off the basic cultivation method: Strength Training Long Fist. Rebate given: Ninth Level Ultra Cultivation Method: Ancient Dragon Mammoth Method!]

[Ding! The host had auctioned off a rusty bronze sword. Rebate give: Ninth Rank Ultra Weapon: God Slayer Sword!]

[Ding! …]

As such, Lin Mo’s insane path to greatness has begun!

When I was reborn in South Korea, I wanted to live my life in peace. Pass the activation system, unlock the 'Big Brother' career, obtain the invincible system, and embark on the road to power
