"Fuel collection method: collect fluorescent fruits in caves. When you see a different kind of ore, you break it with a pick. After entering the cave, it is actually another world. There are cave spiders, whose nests can be broken with pickaxes, and there are banana trees inside, which can supplement hunger and health. The cave is dark for 24 hours. Get ready to go. Stone shrimp can be bought with stones, and rabbit can be bought with radishes. Don't bring meat in front of rabbit, or it will attack you. There should be many glowing mushroom trees and fluorescent fruits around the radish house.
