A spiritual power testing device co-developed by the Song family, used in the Federation for testing spiritual power. It compresses transmitted spiritual power to one ten-millionth to prevent damage to the small and fragile device. Each person's headgear connects to a conduit controlling their team's mechanical hand. When teammates exert spiritual power, it collectively influences the strength, accuracy, and precision of the mechanical hand. Song Jinze could remotely manipulate its internal data but chose not to cheat.
