I Turned In Trash from the Start, and Now the Nation Begs Me to Stop Sending It!

[System + subverting expectations + handing things over to the nation + the rise of a great power + the Myriad Worlds + invincible + comedy]

“Chief, I want to hand over the foot-washing water of the Supreme Lord Lao!”

Lu Yu shows up at the National Security Bureau with a bucket of murky green waste water and knocks on the door.

Bound to the Myriad Worlds Recycling System, Lu Yu can hand over abandoned junk from the Myriad Worlds to his country.

At first, the nation refuses, even suspecting he's seriously mentally ill.

That is, until researchers discover that the “waste water” can regrow severed limbs!

Next, Thanos's tattered underwear becomes a conceptual-level bulletproof vest, and the First Emperor's discarded terracotta warriors transform into divine generals guarding the nation!

The world's major powers are completely dumbfounded. How did the Dragon Nation suddenly become invincible?

When Lu Yu knocks again, dragging along a nine-clawed golden dragon that's barely alive, the chief breaks down in tears:

“Please stop bringing us things. The national treasury really can't hold any more!”
