Clearing an Isekai with the Zero-Believers Goddess

I slowly advance inside the gray sea.

I am using [Underwater Breathing], so there’s no problem even in the water.

The colorful southern fishes were swimming leisurely, but they weren’t painting a picturesque sight in the gray waters.

I saw the beautiful south seas when I came here with Cain 1,000 years ago, but I didn’t feel like it here.

(The Deep Sea Temple is…over here, I guess?) (Makoto)

I get out from the Herbung Archipelago’s beach, and I slowly go deeper and deeper into the sea.

It is a big and wondrous coral reef for a while, but from there on, there’s a place where it gets deep in one go.

(Here…) (Makoto)

A sudden inclination as if it were a cliff.
