Lu Yuan, an ordinary college student, woke up to a forced pop-up on his phone: [Warning! The 'Reaper' fleet has locked onto the solar system and is expected to arrive in 90 days! Assessment of human civilization: probability of destruction 99.98%]. At the same time, a golden finger who calls himself [Doomsday Preparation System (Fire)] binds him. The core mission is to lead human civilization to survive within 90 days!
The world is in panic and order is on the verge of collapse. The Huaxia State showed amazing decisiveness and immediately announced that it had entered the [Level 1 combat readiness state], and the national system was operating at high speed. But Lu Yuan, who obtained the system, squatted in a rental house, dismantled the refrigerator, microwave oven and old computer, and used the advanced technological knowledge provided by the system to create a simple electromagnetic rifle that could penetrate armored vehicles!
"Host, your human foundation is so poor that the system can't help you!" The system complained every day.
Countdown reaches zero! The rhombus-shaped "Reaper" motherships that blocked the sky jumped out of the wormhole, and the cold will of destruction enveloped the solar system. However, what awaits them is not a lamb to be slaughtered, but a huge chain of war fortresses starting from the orbit of Pluto and extending to the asteroid belt! Countless space carriers, rail gun arrays, and swarm drones with five-star red flags printed on them are like the Great Wall of Steel! Lu Yuan stood on the command seat of the "Kunlun Mountain" space carrier, looking at the ferocious alien fleet outside the porthole window. With a cold arc on his lips, he announced to the entire galaxy through an all-channel broadcast:
"Reaper? Welcome. This is the steel cemetery you reserved! Fire!"
