After rebirth,I Started by Building a Star Destroyer

YanXingYe was supposed to become the youngest Nobel Prize genius in history.
Instead, his "Academic Overachiever System" dropped a bombshell:
The world will end in two years.

Then it unlocked a new feature - livestream reward draws.

While the world watched him as a joke on streaming platforms, YanXingYe began his impossible project:
Building a Star Destroyer from scratch.

Day 1:
"This guy's a clown."
"Another fake science streamer."

Day 20:
"Wait... is that a nuclear reactor?"
"Did he just build a real-life Iron Man suit?!"

Day 100:
Governments start paying attention. Intelligence agencies panic.

Two years later, dimensional portals tear open the sky. Giants step through. Humanity trembles.

YanXingYe smiles calmly.
"Bring out the cannon... No, the Star Destroyer Cannon. Let's give our guests a proper welcome."
