Galaxy Defense Line: Bloody Battle in Alien Nest

In 2187 AD, humans discovered an unknown biological sample in the underground ice of Mars. Seven days later, contact with the Mars colony was lost. When Marine Lin Zhan's quick reaction force arrived, what they saw was a bloody hell - buildings were corroded by some kind of acidic slime, and human remains were strangely crystallized. And the most chilling thing is that those "corpses" that were supposed to be dead are reorganizing into new horrific forms. This was the first contact between humans and the Zerg. This alien race, capable of devouring organic matter and evolving rapidly, broke through the Martian defense line within three months. When the first Zerg biological ship appeared in Earth orbit, humans finally understood: this was not an encounter, but an order to exterminate. In this war concerning the survival of the race, Lin Zhan gradually grew from an ordinary mecha pilot to the core commander of the human coalition. He will lead a combined force of psykers, mechs, and space fleets to fight against the Zerg on every battlefield in the solar system. From the deserts of Mars to the lava seas of Mercury, from the deep seas of Uranus to the ice sheets of Neptune, every battle is rewriting the destiny of mankind. But the most dangerous enemy may not be in the stars, but in the human heart. When Lin Zhan discovers that the Zerg may possess intelligence, but that human leaders are secretly developing "destruction weapons", he must make a choice: Should he completely eliminate this threat, or find a way to coexist? In this dark universe, hope is like a spark, and he will be the one who starts a prairie fire.
