[Genius Math Girl × Resilient, Protective Older Sister]
The little sister Zhuang Xueyuan rescued from the river and warmed against her chest, Wu Yan, was both a jinx and a genius. Later, people from Country Z came to take her away, saying she was a national treasure!
Wu Yan could calculate everything in the world, except her sister’s true feelings.
When the state recruited her, her sister’s entire memory was erased.
Then one day, the System showed that her sister was “living a peaceful life”
but Wu Yan saw the lie in the eyes of those around her.
