The alien fleet tore through the defenses of the solar system, turning the earth into a scorched earth battlefield. {Zhang Heng} is the last commander of the "Deep Space Defense Line" project. He led the remaining human fleet to retreat to the hidden star field in the asteroid belt.

In a desperate situation, {Zhang Heng} led the crew to repair the warship, search for supplies, and secretly detect the enemy's movements. When he accidentally intercepted alien intelligence and discovered that the enemy fleet's energy lifeline was actually tied to a star supply station, a desperate counterattack plan was quietly brewing - detonating asteroids, blowing up the supply station, and igniting the last glimmer of hope for human civilization.
