Southern Plain, when a steel torrent shook the earth.
Beneath the ground, feeling the tremors, constructs of steel and flesh had awoken from their dormant state.
Spider Main Battle Mecha, model number A-180, its meat tumors actively wriggling, awakened from its standby mode.
Hao Guyu, the pilot of this Spider Mecha, took a deep breath as his neural sensors connected with the mecha's biological radar.
This biological radar specialized in acoustic detection, infrared radiation, and electromagnetic pulse detection, capabilities that also existed in the natural world.
The sonar of bats provided inspiration for radar development, and serpents used infrared radiation to track and capture prey, like the famously known Rattlesnake Missile. Its initial design was inspired by the desert rattlesnake of California in Beautiful Country.
The sensor nerves on the duck-billed platypus's elongated, flat bill could detect electrical pulses emitted by prey in murky waters.
