On the sea, unmanned warships also began to unleash their might.
They were smaller than the main warships, but had the advantages of greater numbers and faster responses.
Small missiles, long-range rockets, and electromagnetic rapid-fire cannons fired continuously, making it difficult for the Demon Clan near the coastline to assemble.
Submarines cruised farther out, their sonar constantly searching the seabed as they prepared to provide nuclear strike support.
The Demon Clan had already occupied the oceans on Terra. Great Xia would not forget that threat.
The fleet was not only attacking land. It also had to hold the waters off Antarctica.
As the sea, land, and air forces opened fire simultaneously, the orbital weapons in space were not idle either.
In Low Earth Orbit, Great Xia's armed satellites slowly adjusted their orientation.
The satellites' outer shells bore mottled scars left by nuclear dust and micrometeorites.
Yet they were still working.
"Satellite Eleven entering irradiation window."
"Energy reserves at sixty-two percent."
"Cooling system normal."
"Target: rear ranks of the demon tide in the direction of Eolseu, suspected high-ranking Demon Clan command node."
Inside Tianshu Underground City, the orbital fire controller rested both hands on the console, awaiting final confirmation.
Han Niba glanced at the target image.
In the direction of Eolseu, a slightly larger demon stood among the Demon Clan's rear ranks. The demons around it moved in a noticeably more orderly fashion.
"Fire authorized."
"Roger. Firing orbital laser."
In space, a point of dazzling white light lit up at the satellite's front end.
The next second, a laser almost impossible to catch with the naked eye pierced the atmosphere and struck the Antarctica Ice Sheet.
A straight, incandescent white line slowly sliced across the demon tide's rear ranks.
The demons swept by the laser rapidly heated up and finally carbonized.
