The Almighty Princess of the Disabled Prince

In the 21st century, Mi Chonghua Qingyan traveled through time to an orphan in Beichen Kingdom. What? She has no father, no mother, no background, and lives by begging on the streets every day. Is there any time traveler who is worse off than her? Fortunately, Hua Qingyan, a young genius from the 21st century, came through. From then on, she opened a clothing store, refined salt, made milk tea, and opened a hotpot restaurant. She did whatever it took to make money, and by the way, she helped a certain prince seize power.
