"You knew about the Great Old Ones?" Irina was also staring at Mag with surprise. She switched her thinking, and said with realization, "No wonder you knew how to kill Borg and Alfred who were bewitched."
"I simply happened to read a little record about it in an old parchment book. I thought it was an unofficial history that was randomly written. I didn't expect them to really exist." Mag touched his nose. He indeed didn't expect the Cthulhu Mythos to really exist in this world.
He had almost read through everything about Cthulhu Mythos recently, and had absorbed many works of imagination from the authors on Earth.
He also couldn't differentiate how many of them really knew the Great Old Ones, and how many of them were reimagined after they were influenced by the mythological system that Lovecraft established.
However, after being baptized by these classics, he had a basic understanding of the Cthulhu Mythos.
