After opening her eyes, Fuli unlocked the portable synthesizer! Are supplies scarce in the apocalypse? Unlimited synthetic top-quality meat! Unlimited synthetic antibiotics! Unlimited synthetic heavy firepower! While others were still going crazy over a box of cans, Fuli stayed at the base watching movies and playing games.
