Being a Savior with a Mermaid in the Apocalypse

Before the apocalypse, Zhang Fuli was an ordinary reservoir attendant. Even after the apocalypse, surrounded by people with supernatural abilities, he remained as ordinary as ever.

But he never expected that meddling in other people's business and saving a child would get him bitten by a zombie. As he lay dying, he swore that if he got another life, he'd never stick his nose where it didn't belong again. He never expected to open his eyes and find himself back on the day before the apocalypse.

Reborn! This time, he's going to sweep aside the zombies, conquer the world, mind his own business, and go back to being a lazy couch potato!

But wait... "Huh? Why is there a mermaid in this reservoir?"

Little scene:

When Zhang Fuli first found Chen Ming, he thought the guy was kind of clueless. He was a fish and didn't know anything, so Zhang Fuli would have to look after him, teach him, and comfort him.

But then...

This mermaid has MAX combat ability. He's always ahead of Zhang Fuli when fighting zombies, killing people, and even driving!

And why is the way he looks at me getting stranger and stranger!?

Zhang Fuli shouted, "Hey! You're a fish and I'm a human. We're reproductively incompatible! Don't come any closer!!!"

Chen Ming: "We'll never know if we're compatible unless we try."

Note: The shou isn't actually as ridiculous as the blurb makes him sound. "Nervous fidgeting."

The shou isn't an ordinary reservoir attendant, and the gong isn't an ordinary mermaid either~
