I Use My Wife System to Dominate the StarCraft

After her parents died one after another and her property was seized by her relatives, Eve, who was struggling in the slums, suddenly got a system.
　　The system said:
　　"You are actually the real daughter of the Duke's family who was maliciously swapped. They will take you home in a few days."
　　"You have a fiancé, who is the third prince of the empire and the son of luck in this world. He will inherit the throne in the future and unify the five major planets to become the highest authority in this galaxy."
　　"My mission is to train you to be a perfect queen and the woman that the son of luck loves the most, so that you can stay by his side and take advantage of his luck." "
　　Don't worry, no matter how many children you give birth to, you will still have a perfect figure, a noble status, and be spoiled for life."
　　After saying that, the system showed Eve its mall for fear that she would not believe it.
　　Eve's eyes passed over the things that the system strongly recommended, such as "Ice Skin and Jade Bones", "Eyes Like Autumn Water", and "100% Childbirth", and her eyes fell on the special price area on the side.
　　Loyalty pills - can make your maids and guards loyal to you, so you can better manage your harem~
　　Political talent - a simple vase can't catch a man's heart, smart and beautiful women are the favorite of men~
　　Martial arts talent - a little practice can give you a surprise, just be a hobby~
　　The system on the side is still planning the life of a "perfect woman" for Eve, but Eve is thinking: Since I have all these, why should I please that shitty third prince? Wouldn't it be nice to be an empress myself?
　　Is there anyone who dares to say that the empress is not a perfect woman?
