The earth has fallen, and human civilization is crumbling under the iron heel of pterosaur invaders. Yu Chenyi, a dying soldier, accidentally activated the "alien creature analysis system" and gained the ability to see through all things. He can see through the fatal weaknesses of pterosaurs, analyze ancient technological blueprints, and turn ordinary weapons into dragon-slaying blades. From struggling to survive in the wasteland to leading a team to fight back in desperate situations, he turned the tide time and time again with his extraordinary wisdom and precise strikes, becoming the last hope of mankind. However, when the fortress cheered for victory, the system revealed the tip of the iceberg of the "biological assimilation" plan of the pterosaur civilization, and a more powerful interstellar threat was approaching from the depths of the universe. This victory only attracted the real destroyer... Humanity's counterattack has just begun!
