One infinite supply available per day. Congratulations, you got Unlimited Mineral Water.

All humans across the globe are suddenly transported to a perilous doomsday world. Zombies and mutated creatures roam everywhere, leaving everyone struggling on the brink of life and death. The protagonist Chen Dong accidentally activates the Infinite Resource System, which grants him one type of unlimited supplies each day. Starting with unlimited mineral water, he trades water for all kinds of goods via the trading channel and quickly stockpiles food and daily necessities. While others suffer from hunger, cold and constant fear, he gains a firm foothold easily. He also collects basic materials from supply crates. Now, a cry for help comes from outside, marking the beginning of this doomsday survival tale.
