Ch. 902Machine Insect
Yang Bo designed and built a fist-sized Machine Insect to excavate a concealed passage from his Underground Fortress to the Underground River. The Machine Insect completed more than half the excavation before returning with its Energy Stone nearly depleted, and Yang Bo considered making more for emergencies.
- Yang Bo studied the geology beneath his villa and decided to connect his Underground Laboratory to the Underground River with a small excavation robot.
- Yang Bo gathered materials as Bart and used Mechanic mode to build a fist-sized, Energy Stone-powered Machine Insect modeled on a Dung Beetle.
- Yang Bo cut through the Underground Fortress’s layers of Battleship Armor and concrete-like material, then sent the Machine Insect into a crack in the surrounding rock to begin excavation.
- Yang Bo considered adapting Machine Insects into stealthy Energy Bombs, but recognized their costs and the risk of detection by active Energy Defense Systems.
- The next day, Yang Bo found the Machine Insect had returned automatically and read its progress, discovering that it had completed more than half the passage with almost no wear.
