"Every time I die and enter that pitch-black environment, I would feel around the area. Once I found a Level 1 pickaxe and a train order; that's when I started mining alone to build a train."
"All the other goblins are asleep; I tried waking them up but to no avail, so I could only mine by myself."
"I don't know how long I've been mining."
"And eventually I crafted that Level 2 goblin train."
"As for that drill, it's a Level 1 'Goblin Train' built-in white accessory with effects like breaking rocks and traversing underground, though it consumes energy quite quickly when activated."
"Upon upgrading to a Level 2 'Goblin Train,' there's a green-grade built-in craftable accessory, 'Nanomaterial Armor Paint,' which covers the train surface with a layer of black paint to block radar perception. I upgraded it to Level 3 for concealment."
"Enemy radar below Level 3 cannot detect my goblin train."
