The Four Symbols Shatter the Skies

Reborn as a cannon-fodder character, my golden finger is a life simulator. I only wanted to defy fate and change my destiny, but I was forced to team up with three oddballs: a Demon Lord reborn from a sea of blood, a scientist who can build a Gundam by hand, and a bankrupt heiress with a pocket dimension. When a strategist, a bloodthirsty fighter, a top student, and a rich woman start cultivating together, this world is probably in for a rough time.
