Through brain‑computer interfaces, users can remotely control tens of thousands of genetically engineered war ants and mechanical soldier ants to form “Haiqun” swarms, enabling them to launch three‑dimensional raids in complex aquatic environments such as deep seas, flooded areas, and urban waterways. The “Soldier Ant‑Type 9” exosuit is seamlessly integrated with the user’s neural interface, leveraging water currents to execute tactical maneuvers in milliseconds. Equipped with an onboard underwater propulsion system and pressure‑regulating mechanisms, this exosuit allows for unassisted combat operations at depths of up to 10,000 meters—and its nanorobotics-enabled repair systems can mend damaged body parts in real time.
