I Draw Talismans and Temper My Body in the Wasteland

In a post-apocalyptic wasteland, baleful energy fills the skies.

Chen Yu awakens a bizarre ability:

He tears the bones from his enemies and forcibly extracts talismans from living corpses!

With his tagalong little sister on his shoulders and a vicious blood pact wrapped around him,

he draws talismans by taking hits, withstands the beast furnace burning his body, and treads on withered bones to render them into oil!

He forges talismans from flesh and blood to make armor, and turns baleful energy into the patterns of his bones!

When gods and demons from across the heavens covet the Key of Unending Ashes in his arms...

“You want it?”

Chen Yu bares his bloody grin, clutching a talisman made from his enemy's bones as he sneers:

“I'll drain your life-bound talisman dry and render it into oil too!”
