Storyline

500 years later, humans are forced to move to the space station near the Earth to stay away from the lethal virus on Earth. But finally the virus is transmitted to the space station. Soon there is a split within the Federation in space between the "Colonists" and the "Reconstructionist". The "Colonists" advocate starting interstellar colonization, abandoning Earth, and harvesting all available resources, including minerals and seawater, before leaving the planet, draining the entire planet. The "Reconstructionists" advocate rebuilding the Earth, modifying the evolution of human DNA to readapt to the Earth's harsh environment, and working with the Earth's remnants to restore the Earth's ecology. Due to the long-standing conflicts between the two sides, the "Colonists" suddenly launch an armed rebellion in the space station, and the war is taken to space. After a vicious war, there is no winner. Both sides suffer heavy losses, and the Federation is once again shattered. Most people die in this civil war in space. The Earth orbit is filled with space station wrecks. Only a very few survivors are floating and wandering in space. The human race is at stake...... A soldier survives and wakes up in space. How will he stay alive after losing memory...
