My Fish Tank Connects to the Deep Sea

In the apocalypse, natural disasters ravage the world, the seawater is polluted, and bizarre monsters keep pouring out of a vortex in the abyss of the deep sea.

Fortunately, humanity has evolved supernatural abilities and can fight back against the monsters.

Yu Xihe is an ordinary person whose greatest loves in life are fishing and keeping fish.

Because she has no supernatural abilities and refuses to give up her ornamental fish, which could become contaminated, her family looks down on her and her boyfriend betrays her.

One day, a bolt of lightning strikes her fish tank.

A tiny vortex appears inside it, and all sorts of extinct marine creatures swim out from time to time.

[Congratulations, Host. You have successfully bound the “Marine Civilization Revival System.”]

[Your fish tank is now connected to the ocean.]

So she cleans her fish tank every day, and the ocean's pollution is gradually purified.

She plants aquatic grass, giving the creatures in the ocean more clean places to live.

She feeds the little fish in her tank, and the marine creatures slowly grow stronger and begin to thrive.

Later, when a group of S-rank ability users set out to challenge the source of the world's pollution once more, the vortex in the abyss of the deep sea, they are astonished to hear a woman's voice coming from inside it: “I changed the water and added extra food today. Be good and grow big!”

Then the well-fed marine creatures of myth tear apart the monsters trying to surge up through the vortex.

*Reader's guide:

The marine civilization in this story includes not only ordinary marine creatures, but also various beings from sea mythology.

There is a male lead, and the romance develops slowly.

The female lead grows stronger and becomes formidable.
