This is a love-hate relationship that takes place in a broken time. Every time you travel through time and space, there will actually be almost undetectable deviations from the time axis. However, when those deviations gradually accumulate to a certain limit, the time of the entire world will be catastrophically distorted, leading to the disillusionment of the world. This is exactly the catastrophe experienced in the twenty-third century. In order to correct the distorted time, people established a time correction department composed of five elites who can travel back to the past. The female patron Yiwei is a member of the Time Correction Department. Their mission is to use technology to go back to the past where time travelers appeared, secretly bringing each time traveler back to the era they belong to, erasing the memory of them and all the "ancients" who have come into contact with them, and eliminating the "time hybrids" that have been produced. Due to some reasons, an accident occurred during the time travel. Four people except the heroine died unexpectedly, and the task fell to the heroine alone. According to the instructions of her superiors, she gradually completed the task along the time axis. When she arrived in the Tang Dynasty, everything began to get out of control - she actually fell in love with the time hybrid (male protagonist) who should be eliminated by humanitarianism! When she couldn't extricate herself from the emotion, she found that the male protagonist had already understood her identity, and all this tenderness was just a fake show. The male protagonist's real purpose is to kill her in a different time, so as to save his family and stay together with his beloved Qingmei fiancée (Mo Xiao)... Is this an arrangement of fate or a man-made operation?
