That's right! I'm shamelessly rating my own novel.
Summary: a man got transmigrated into a merman. Gained abilities from the system. He tries to create his own kind and survive in the apocalyptic. The world background is basically an apocalyptic world where everything can happen. Ghosts, zombies, aliens, vampires, martial art, you name it. The story is still at the starting line but more adventure and lovey-dovey events are in the way. ........ Stay tuned.
