[Two-way door + Nationwide development + Civilization showdown]
In 2026, Lin Yu, the owner of Daxia Machinery Factory, opened a door.
On the other side of the door is the earth 300 years in the future - the sky is covered with poisonous spores, the surface has become a paradise for monsters, and humans are forced to go three thousand meters underground and rely on geothermal heat to survive.
There are abandoned individual power armors, dusty planetary engine blueprints, and top-secret files recording the truth about the "Civilization Reaper" incident.
Lin Yu made a decision: hand this door over to the country!
The destinies of two time and space intersect at this moment.
In the real world, Daxia devotes all its efforts to transport food and resources to the wasteland;
The technology of the wasteland world has turned into the wings of the real Great Xia, breaking all hegemonic blockades.
When that day comes, when the "Reaper" fleet comes to the solar system again.
They were surprised to find that the civilization that was once waiting to be slaughtered was already fully armed and standing on the top of the galaxy.
"This time, humans will never wander!"
