In the misty sea fog, on the deck of the ghost ship, Hern Iheroa gazed into the distance, using a brass telescope inlaid with inhuman eyeballs, at a geometrically indefinable outline. He mechanically tore at the rotting fish flesh in his hands, stuffing it into the relatively neat slit in front of his skull, known as the "mouth." At that moment, only two questions occupied Hern's mind. First, when would he find a doctor? Second, what about the remaining 1,278 mouths on his body after he had eaten his fill—"So, doctor, is there... any hope for us?"

The matter that makes up the world we know only accounts for less than 5% of the mass of the entire universe. So where is the other 95% of the universe's mass? What is it like? A soul that travels across time and space accidentally encounters a mysterious and strange shadow world. Tearing apart the bloody and ignorant appearances and dispelling the mysterious and strange fog, evolution and truth unfold before his eyes. P.S.: The original inspiration for this book comes from the American TV series "Stranger Things".
