[Assassin's Creed] The Aunt and Sister-in-Law's Sea of Stars

For the chance to earn up to 6,000 a month, Qin Ye cranks the realism of a Ubisoft VR game to the max. The moment she opens her eyes, she's Eivor, a fierce woman drenched in water. The System warns her: Don't act weird, or you'll be hit with a massive compensation bill. But unemployed wage slave Qin Ye can't act, knows nothing about being a doting older sister, and finds it hard to be gentle. Being bold is out of the question. Her only interest is making money, lots of money, and she has absolutely no talent for performing. So she decides to cozy up to her seemingly gentle and amiable sister-in-law, who's actually deeply calculating. She carefully maneuvers her way between power and family; She keeps bouncing back and forth between acting out of character and getting too caught up in her role. As she keeps leaping between the two, she has no idea that she's already rewritten history and embarked on a kingly path of conquest. Warning!! Not for people who are obsessed with older brothers! Theme: I don't seek true love, only fame and power among the feudal lords.
