From the Start, I Teased the First Emperor

After transmigrating, Bai Su happens to run into the disguised Princess Zheng and mistakes her for his betrothed!

Bai Su: "Miss Zhao, this is your father's marriage contract. If you're willing to marry me, then from today on, you'll be my wife. I'll make sure your wedding is a grand affair."

Princess Zheng: "..."

Bai Su: "I heard she's recently gathered a bunch of alchemists and sent them to Xianyang. At this rate, she probably won't live for more than a few years."

Princess Zheng: "...!!!"

Bai Su: "The Great Xia is doomed. Once the empress dies, chaos will follow. Let's hurry up and make money and stockpile food, so we'll have someone to turn to when the heroes rise up."
