Under the haze of the fall of Peking, mathematical genius Cheng Jianwei has two identities:
On the surface, she is a gentle lecturer at Yenching University;
Secretly, she is an underground codebreaker codenamed "Anxiang", using logic as a sword to decipher the Japanese invaders' secret messages.
However, when her sister Cheng Zhizhu, her closest relative and comrade-in-arms, suddenly "sacrificed", the rational world she relied on for survival began to collapse.
Deeper fog ensued:
Why did the jade bracelet that my sister never left her body appear on the wrist of a strange doctor, Shen Hanqing?
Gu Zhixing, a close friend who came to the rescue at a critical moment, why did the details of the wound fail to withstand mathematical scrutiny?
Is that bitter almond as a signal awakening the truth, or is it leading her into a deeper trap?
This is a war that uses probability to calculate human nature and logic to measure loyalty.
In the crisis where the hidden fragrance floats, she must stay absolutely awake——
Because the most fatal blow often comes from the most trusted direction.
"The secret fragrance floats, the faith lasts forever"
Intention: The fragrance floats, the faith lasts forever
