In 2147, a meteorite named "Ash" hit the earth and released radiation that killed 98% of the world's population. Among the survivors, a few have awakened incredible powers - fire control, electricity control, mind reading, and teleportation.
As for Lu Chen, what he awakened was the most useless ability: he could condense a faint light in the palm of his hand, which was not as bright as the screen of his mobile phone and lasted no more than three seconds.
"You are not even qualified to be a light bulb." This is everyone's evaluation of him.
But when an unknown monster "Dark Eater" that can devour all supernatural powers began to slaughter human strongholds, Lu Chen discovered that those so-called geniuses with supernatural powers were vulnerable to the monsters.
And the glimmer of light in his palm that was ridiculed is the only weapon that can make the monster disappear into ashes.
"The strongest power often wears the most inconspicuous cloak."
From an abandoned wasteland wanderer to the last hope of mankind, Lu Chen must find the truth of this doomsday catastrophe in a world that has lost order - and the ultimate secret behind that glimmer of light.
