Abyss Revelation

Human beings have only existed in the world for a few thousand years, and before that, in the distant old days, there must have been creatures that dominated the world just like humans. They were often not humanoid, and they might not even be describeable in human language. I call them "Old Rulers." The terrible creatures that fall in the sky and among the stars and come to the world are "natural disasters". And whether it is the "old days" or "natural disasters", they are existences that cannot be spied on or looked directly at. When a human being wants to know them and sees too much, he will be contaminated by them and become like them, turning into a "man-made disaster" (Due to the serious lack of coordination between the artist and the writer, the cover could not be completed as expected. My original teacher has deducted the artist's fee, and the new cover is being revised urgently. Please be patient) (The original name of this book is "Apocalypse of the Abyss". I don't know which book it collided with, so I changed the name temporarily)
