After Binding to the Exchange System, I Gave Everything to the Nation and Became the Richest

Ye Muqing is suffering from cancer. Abandoned by her sexist mother, who favors sons over daughters, she lies in her rented room waiting to die. Her overwhelming unwillingness to accept her fate causes her to become bound to the suddenly appearing Interstellar Exchange System! A bunch of discounted flowers gets her a bottle of Interstellar A-Grade Repair Fluid. Not only are all the cancer cells in her body removed completely, but her body also suffers no harm whatsoever.

The system tells her that, because Little Broken Planet in the future was attacked by aliens and no culture was left behind, it bound itself to her to obtain the culture of ancient Earth. Ye Muqing's blazing patriotism is ignited. Since she can exchange for interstellar items, why not be a little bolder? Can't she exchange for an interstellar warship and hand it over to the nation?

The next moment, she receives a new exchange mission: exchanging items with people from ancient times. One bowl of noodles in exchange for a peerless painting worth millions? It turns out that the Exchange System can trade not only with the interstellar world, but also with people from ancient times! What? The Yongle Encyclopedia and the Qing Nang Shu? Ye Muqing is even more excited! Exchange them! She absolutely must exchange for them!! She is going to bring over every bit of the finest treasures from ancient times and the future, determined to revive Little Broken Planet's technology and civilization and change its fate of being destroyed after the alien invasion in the future!
