Making money: early route, what to sell and steady income

Shops buy at half an item’s base value unless they override the price for that item, so a 10,000-value item sells for 5,000. Because your carry weight is the limit, pick up by value per kilogram: small electronics, valuables and graphics cards beat heavy furniture-grade junk, and the loot value table sorts every item that way.

Early money route by map

Three guides (9game in Chinese, the 21 Practical Tips guide and Kotaku) agree on two rules: sell duplicates instead of hoarding them, and keep anything a later quest or building asks for. The quest items list gives the counts.

Stage	Money source	Notes
Ground Zero, first raids	Jeff’s opening quests: Welcome to Duckov! 300, Startup Capital 1,296	Sell common supplies; Red Envelopes are worth 1,817 at 0.1 kg. Opening them is a gamble with positive expected value; sell when you need cash now.
Ground Zero, Pato Chapo	His guaranteed AK-47 and Lv.3 Body Armor	Keep one rifle of each type and sell the rest; boss rifles are the steadiest early income in the 9game guide.
Warehouse Area	Jeff’s Extract Fuel pays 4,000 and unlocks AP Bullet (AR); Xiaoming’s Mark Life Support Pods pays 10,000	Lordon and the Speedy Group Commander drop sellable guns and armor; see the boss guide.
Farm Town	Hidden Mine PC cases (graphics cards), City Hall safes, Mysterious Rooms X and O	Fading Feathers from kills sell, or feed the sewer chalk circles for totems.
Later	Bitcoin Miner, Black Market orders, J-Lab crates, Mysterious Room Z	See below.

Do not sell these early: graphics cards (the Bitcoin Miner uses them and Xiaoming’s Super Core asks for two) and Mysterious Keys X and O, which open Farm Town’s best rooms and combine into Key Z.

Why a field merchant will not trade

Selling at the bunker pays into your account, not into cash in your inventory. Merchants on the map accept only the cash you carry, so clicking Trade does nothing when your pockets are empty. Withdraw cash at the bunker ATM before the raid, or at the Farm Town City Hall ATM. Field merchants can be cheaper: the 21 Practical Tips guide quotes a Kukri at 12,839 at base and 10,271 from a field merchant.

What to keep, what to sell

• Keep quest hand-ins. The quest items list totals every item quests ask for; selling a Space Crystal or Super Glue you need later costs more than it pays.
• Sell common supplies. The game’s own loading tip says it may be better to sell common supplies.
• Dismantle at the workbench when the parts are worth more to you than the sale; update 1.3.10 made weapon attachments dismantlable.
• Fish sell well for their weight when they are the rare weather fish; see the fishing guide.

Where the money is on each map

• Farm Town: the Hidden Mine has many PC cases with graphics cards; Mysterious Rooms X and O hold high-value loot and J-Lab colour cards; City Hall has safes.
• J-Lab: colour card rooms and J-Lab crates with lab-only materials.
• Storm Area: Mysterious Room Z and J-Lab crates; the Crown, worth over 21 million base value, can appear in Mysterious Room Z since update 1.3.12.
• Safes everywhere hold at least two items since update 1.1.6 and can contain collectibles.

Income that does not need raids

• Bitcoin Miner: a bunker building that earns while you raid. Its slots take graphics cards, which set its hashrate; a Graphics Card SLI fits three cards into one slot at some loss of performance. Building it earns the achievement Passive Income. The 3D Printer spends hashrate to print items.
• ATM: deposit cash in the bunker. The Self-made Success, Middle Class and Millionaire achievements count savings of 10,000, 100,000 and 1,000,000.
• Black Market Contact Point: buy and sell orders with fluctuating prices (“WTB at High Price” orders pay above normal). Upgrading it fully earns Wealth from All Sides.
