A special mission failed. Agent Qi died but was reborn in time. She was reincarnated as Li Lige, the youngest daughter of the Shangshu Mansion. She had parents and brothers who doted on her, a distinguished identity that did not have to come and go in blood and rain, a close friend who fought alongside her as a general, and a noble lover who loved and protected her. But the world is overturned, and happiness is shattered in the blink of an eye. Her hands are stained with blood, and she is fighting on the battlefield. She is Li Lige, and she is also Agent Qi. Who holds up a world with the firmest faith, who exchanges love with the most passionate entanglement, and who protects the health of others with the most forbearing sincerity.
