Ninth Line of Defense

That day, disaster struck without warning. Extreme cold follows like a shadow, storms tear apart the sky without any pattern, and the world is dragged into despair in an instant. When the world falls into catastrophe, where will humanity return? The strange alien species gathered into an endless tide of beasts, swallowing everything like a black tsunami. Ji Chen once thought that his only thought was to survive. But in this disaster, who can really be immune? Lines of defense collapsed under the impact of the alien species, and corpses fell in front of Ji Chen. He fell silent, unspeakable regret welling up in his heart. Thousands of people screamed in their ears, and thousands of pairs of desperate eyes were in front of them, silently praying for life. Ji Chen finally understood - no one, no one can stay out of it! If the defense line is broken, everyone will die! I will die and so will you. We have no retreat. Either die like dust, or die heroically with blood. Fuck the aliens!
