Love and Qing Dynasty, but as a Maritime Merchant

After transmigrating into the daughter of the Imperial Household Department's director, who also serves tea before the emperor, Ying Xia hears a voice the very first time she reports for duty:

System: Play [Love Through the Qing Dynasty] and become a happy woman! I'm your personal guide. Embark on a heart-fluttering journey with four male leads to your heart's content! Earn every last bit of Heartbeat Points and fall in love with the one fate has chosen for you!

Ying Xia's little hand trembled as she nervously looked at the four bald men in front of her. She almost let out a string of curses.

Damn, what kind of messed-up romance game system is this?

System: First, Fucha Fuheng, a noble young gentleman from a distinguished family, and a brilliant young general with a wealth of military achievements!

Ying Xia: He spends all his time away on military campaigns while he's alive, then dies young. How is that any different from being a nun?

System: Second, Aisin Gioro Hongxi, a domineering older man and Kangxi's eldest legitimate grandson. If his rebellion succeeds, he will be the rightful emperor!

Ying Xia: His father was driven to that state by his grandfather. He's bound to have childhood trauma. No way!

System: Third, Heshen, a master of words, handsome and charming. He's still a little puppy now, but he'll definitely become a Grand Secretary in the future!

Ying Xia: Corrupt and greedy, and he'll end up with his estate confiscated. Could you at least wish me well?

System: Fourth, the ultimate male lead of this romance game: the Emperor Qianlong, a man of both literary and military talent, charming and amorous!

Ying Xia: One wife died and another went mad. He has bizarre taste and a weird obsession with stamping things. He's the culprit behind closing the country to the outside world. He's way out of my league!

Ying Xia's thoughts shifted. If she could pursue all four of them at the same time, couldn't she end up choosing none of them?

System: Player, you're playing with fire!

Ying Xia wagged a finger. "No, no, no. I want to play with water and become a queen of maritime commerce, so I can stop the tragedy of falling behind and getting beaten!"

System: ...

Ying Xia tossed her teacup aside, silencing the System, and quickly came up with a foolproof plan:

Step one: Trade Hongxi's Heartbeat Points for her freedom, leave the palace, and head to the coast;

Step two: Use Fuheng's Heartbeat Points to deal with local disasters and set out on the path of commerce;

Step three: Use Heshen's Heartbeat Points to strengthen ties with foreign countries and expand her business channels;

Step four: Use Qianlong's Heartbeat Points to boost foreign trade and earn back all that shiny silver, damn it!
