Volume 1: Liu Li fell in the snow with an iron piece stuck in her chest, Liu Yang hugged her and cried bitterly.
"Has the list... Been sent out?" Liu Li's breath was weak.
Liuyang choked and nodded, watching helplessly as her sister's hand fell into the snow.
When the wind and snow drowned out her screams, a warm mink fur suddenly wrapped her around her.
Liu Li, who should have died, was weak but sober: "Stop howling... The iron piece is stuck in the ribs... I can't die..."
The morning sun pierced the darkness, and Liuyang cried and laughed: "Old girl, this mask is so... Damn, you're cheating me!"
Volume 2: Liuyang and Liu Li, the most dazzling twin flowers in Harbin, one is as pungent as a red rose, and the other is as cold as a white coat.
They cooperated tacitly at the New Year's banquet of the Japanese military headquarters and delivered the fortress defense plan, but they did not know that each of them carried half a copper coin token that could be assembled.
When Miyoko Matsumoto - the head of the Kwantung Army's secret service - revealed her mechanical left eye, the sisters were shocked:
They are not only clones implanted in different camps, but also the "living keys" that activate the self-destruction program of the Japanese underground biological laboratory.
The only thing that can stop the "Sakura Project" is that they must detonate the resonance frequency of the copper coin at the same time - even if it means dying together.
