The protagonist, Lin Feng, transmigrates into the body of a weak human and binds to a “Foodie System.” He discovers that devouring primordial beasts and spirit plants can raise his cultivation, and that how he cooks them affects the results. Roasting a Lei Ze Kui Ox summons heavenly thunder, while stewing a Yuan Tuo boosts his defenses. From then on, he defeats monsters, levels up, and cooks delicious food, gradually becoming the top gourmet of the primordial world.
