Gu Changfeng traveled through time and became a cleaner at the Dragon Kingdom's Supreme Academy of Sciences.
On his first day at work, he was assigned to the archives room of the "Nantianmen Project" that had been gathering dust for a long time.
Here, the most daring and craziest fantasies of Dragon Kingdom scientists are sealed, but cannot be realized due to technical barriers: mechas, space carriers, curvature engines, Star Destroyer fleets...
Faced with Yingjiang's technological blockade and ridicule, Longguo's scientific research was in dire straits.
And Gu Changfeng, who is bound to the fantasy come true system, can turn these dust-covered fantasies into reality as long as he cleans them away!
When he was wiping out the first "Dragon King" mecha design drawing, a ferocious mecha that was 100 meters high emerged from the secret base 10,000 meters away!
When he swept away the dust on the "Tiangong" space carrier model, a steel fortress covering the sky and sun tore through the clouds 10,000 meters above the sky!
When he dusted off the file with the words "Star Destroyer"...
Yingjiang was dumbfounded: "We are still working on the fifth-generation aircraft, but you told me that the cleaning staff of the Dragon Kingdom have already started sweeping the Star Destroyers?"
The whole world is numb: "How did the promised technological competition turn into a myth?"
Facing questioning from reporters around the world, Gu Changfeng just picked up his broom and smiled sheepishly:
"Don't ask, I'll just sweep it up."
