Transmigrated Genius: Fragile Heiress Reigns Supreme

After years of hard study, she finally became a master's degree holder. One day, she suddenly finds herself traversing into a different world as an illegitimate daughter.
In her previous life, she was a prominent student from a prestigious university; in this life, she is a weak girl from a noble family.
She hides her brilliance, conceals her sharpness, aims for survival, and seeks peace. However, the scholarly family she is part of is also fraught with countless disputes and endless troubles.
The concubine schemes against her, her legitimate sister plots, leading to her ruin and disgrace.
Retaliation is a must!
Her attitude must be gentle!
Her methods absolutely ruthless!
She retaliates fiercely with gentle means, and what's next is...
Marriage?
To whom?
Can she choose her own spouse?
This is a serious issue.
