Era of Magic and Martial Arts

The original Feng Mu was a hopeless wreck, pushed to the brink and driven to take his own life. After his death, a transmigrator takes over his body—and awakens a game-like system: [Ghost Shadow]: They are born from your shadow, yet they are not content with just being a shadow. [Nirvana Breath]: The enemies you kill will rise as zombies to fight for you. [Iron Eater]: The steel civilization is your menu, devour it freely, and then evolve. [Eternal Feast]: The flesh and blood of all beings are the fuel for your immortality. — Description from novelcodex.org
