After Binding to an Exchange System, I Hand It Over to the Nation and Become a Tycoon

Ye Muqing has cancer. Her mother, who favors sons over daughters, has abandoned her, and she lies dying in her rented room. Her overwhelming unwillingness to accept this fate causes her to be bound to a suddenly appearing Interstellar Exchange System! A discounted bouquet of flowers gets her a Grade-A interstellar restorative potion. It removes every last cancer cell from her body without causing her any harm. The System tells her that in the future, aliens invaded their little planet and left no culture behind, so it bound her to exchange for ancient Earth culture. Ye Muqing’s patriotic spirit blazes to life. Since she can exchange for interstellar goods, why not be bold and trade for an interstellar warship to hand over to her country? The next moment, she gets a new exchange mission: trade items with people from ancient times. A bowl of noodles for a peerless painting worth millions? It turns out the Exchange System can trade not only with the interstellar world, but with people from ancient times too! What? The Yongle Encyclopedia and the Qing Nang Book? Ye Muqing is even more excited! Trade! She absolutely has to trade for them! She’ll bring back all the finest things from both the ancient and future worlds, revive her little planet’s technology and civilization, and change its fate of being destroyed after an alien invasion!
