Nangong Yun was a night traveler in his previous life, but he disappeared in the middle of the night during a critical mission. After his rebirth, he became the milky-smelling dad at the kindergarten parent-teacher conference who clumsily tied a bow for the little girl with twin tails. However, the police lights of the anti-narcotics brigade turned on, and Li Feng held up the paternity test certificate and sneered, breaking the calm. What's worse is that the encryption chip he has been looking for for many years is hidden in his daughter's schoolbag. At this time, Nangong Yun has to play the role of a gentle dad, an ex-undercover agent, and a top hacker wanted by a multinational group at the same time. In order to avenge his father, Li Feng joined forces with a multinational group to pursue him and prevent him from protecting his daughter and obtaining the chip. On the one hand, he has to make a difficult choice between protecting his daughter's family ties and completing the just mission of undercover mission. On the other hand, once the identity of the top hacker is exposed, he will be killed. Although the male protagonist has memories of his past life, there is still a gap in strength in the face of powerful enemies, and there are many misunderstandings with his daughter and the anti-narcotics brigade due to identity issues. Multinational groups are searching for chips urgently, and Li Feng continues to cause trouble, causing tension between him and the anti-narcotics brigade. But with the advantage of rebirth, Nangong Yun made plans in the difficult situation, gradually resolved the crisis, and finally defeated the enemy, protected his family, and completed self-salvation and counterattack. However, there was a lot of bitterness behind this victory.
