In a sudden road accident, Qin Yue lost her life while trying to protect her twin younger brother, Qin Xin. But because of the impact from the accident, Qin Xin goes into a coma where he might never wake up again.  Taking all of these in her soul form, Qin Yue becomes saddened at the doctor's reports when a cold, mechanical voice calling itself 707 brings in new hope to save her brother and herself.  [Do you want to save your brother? If you agree to get bound to the counterattack system and become a tasktaker, you can save him.]  Hearing this unrealistic proposal, Qin Yue hardens herself and agrees to it to save her brother. To her, nothing was more important than her brother, not even her own life.  Traveling through time and space, living with different identities. In this place where a person could forget himself, his principles, his real identity, his purpose in life..even his humanity, Qin Yue just grits her teeth as she perseveres through all the task worlds.  Wars, bloodshed, face-slapping, friendship, comradery, plotting and scheming. Whatever the situation, she charges forth without looking back to complete all the missions and save her brother.  But after all that she had experienced in those different worlds, would she still be able to stay the same her inside? Would she still remember her true purpose in becoming a tasktaker? Would she be able to protect her heart from getting moved by someone in the whole process?  "Ah Xin, wait for me to save you."  **** Disclaimer: The cover isn't mine.
