I Owned Earth, but After Reincarnating, the Campus Belle Exposed Me

"What do you mean, this planet is a potted landscape you raised?"

"Thirty thousand years ago, I was bored, so I casually put together a miniature potted landscape and set it on my desk as a decoration."

"The Milky Way is a handful of stardust in that landscape."

"The sun is a fragment of a lamp wick that fell from its display light."

"Your Blue Star is nothing but a speck of dust among the stardust."

"And you humans... are moss growing on that speck."

After his true spirit reincarnates, Li Er becomes a loach and arrives in the potted landscape he created with his own hands. The moss inside it has somehow become the one raising him.

Unfortunately, his mortal loach body seals away 99 percent of his power. The rules he once set for the landscape now bind him instead.

To reclaim his power, he must bring the landscape to fruition: that is, nurture a civilization capable of leaving the glass dome.
