I, the Creator, Rule a Miniature Cultivation Realm

[Invincible behind-the-scenes protagonist + dimensionality reduction + scientific cultivation]

My mother was terminally ill, and reality had driven me to the end of my rope. I spent all my savings on the dark web to buy a busted box that supposedly granted wishes.

But then... I actually became the creator of a world?!

Inside the box was a miniature cultivation world suffering a drought for ten years!

Here, lofty immortals treated mortals like ants, and would massacre entire families for a single spirit herb?

Sorry, but a single tear from me can become a torrential downpour and bring your world back to life!

Here, an alchemy grandmaster's life-extending elixir was worth a fortune, and a single pill could make countless powerful cultivators fight like madmen?

Hilarious. A grain of leftover egg fried rice from my meal is a "Divine Rice Mountain" larger than an actual mountain in your eyes!

Here, even the Immortal Emperor was helpless against the "corrupt-spirit disease," an incurable illness?

Wait, don't give up on treatment just yet! Let me look... Where did I put that box of amoxicillin my mom didn't finish last time?!
