He transmigrates into the world of Slay the Gods as an ordinary passerby, with no System, no template, and no powerful backer.
Gu Yuan thinks he's been handed a cannon-fodder role, until the night the fog descends, when he discovers he can see everything:
The energy trails of every mysterious being, the weaknesses and vulnerabilities of every god, and the hidden currents of fate.
God's-eye view, fully loaded.
When Lin Qiye awakens, Gu Yuan watches the whole situation unfold from a rooftop. When the Night's Watch surrounds an evil god, he's already seen through the deadly trap. When the gods deliver their divine edicts, everyone looks up at the sky...
Only Gu Yuan lowers his gaze, looking toward the god's most vulnerable rib.
“You can see the future?”
“No. I just see things a little more clearly than you do.”
“Then what do you see?”
“All gods... can die.”
He is the eye in the shadows, the third eye in the fog, the one all the gods least want to face:
The man who can see everything.
When he turns the original story upside down, Lin Qiye looks at him. “Who are you, really?”
Gu Yuan smiles faintly. “Just a passerby, with unusually good eyesight.”
