A cold electronic voice announces the start of the game. A death train carries fifty people into a living nightmare.
Survival is the only goal, and trust has become the deadliest lie.
Shen Qingci is cool as ice and taciturn, but her methods are as fierce as thunder. Anyone who crosses her or hurts someone she cares about will pay a terrible price at her hands. She repays every slight a hundredfold.
Su Lingyan is gentle but sharp beneath the surface, sweet-tongued and devious, always presenting a soft front. In truth, she is ruthless and excels at laying intricate traps, using her tenderest demeanor to corner evildoers and slowly torment them.
Two ruthless women, bound by their shared pasts and dependent on each other for survival, stumble into the same infinite instances.
There is no romance between them, only a bond of friendship that lasts until death.
They refuse to be helpless lambs led to the slaughter, and they refuse to become monsters without a conscience.
They hold fast to the rule of never harming the innocent, but show no mercy to the wicked.
Train cars riddled with deadly traps, instance after instance testing the human heart.
Some betray their companions to survive; others abandon their conscience just to cling to life.
Only the two of them work together in perfect understanding, one plotting and one deciding, one gentle and one fierce.
They tear off hypocrites' masks and punish the wicked, bringing justice to the world. Amid the endless cycle of killing, they fight evil with evil, take their revenge, and become the brightest light in this game of despair.
