Making Money Guide
Game Version: 0.4.16
In order to do this, you must have a lot of Copper Ores. If you lack them, I suggest you buy them from Duyi.
- Buy the blueprint of Piranha Drone.
- Buy some Water Pumps. Each one costs 270.
- Place these pumps, then scrap them by using your mining laser. You can recover 4 or 5 Aluminum Ingots, some Steel Ingots and one Basic Circuit.
- Crafting Piranha Drones and sell them. You can also sell those Steel Ingots.
