259 Earth Orbit Defense

Bai Zhongqi looked up at the sky, seemingly crossing millions of kilometers of space to see the arrogant reconnaissance ship mocking the Star Alliance's defense system.

Under Maelus's command, the Teizene reconnaissance ship, after dodging direct hits from two laser cannons, performed an action like an insect spreading its wings. A pair of "wings," made up of countless translucent elliptical arrays, seemed to tremble faintly in the sunlight.

Bai Zhongqi recognized it immediately because Iridium Star had also developed the same technology—these were solar sails, used for interstellar travel when speed was not a priority, propelling by means of light pressure. In theory, as long as there was stellar light, this propulsion method could allow a spacecraft to travel indefinitely with little or no energy supply.
