Courier Zhao Dabao was accidentally involved in an operation of the National Security Bureau while delivering a package. He accidentally absorbed the "flesh and blood of the beast" and became a mystical person. He was brought back by National Security Bureau investigator Zhou Weiguo.
Faced with the choice of "joining the National Security Agency" or "life imprisonment", he chose to undergo training.
In the training camp, he underwent special physical training, awakened his abilities, and passed the assessment to officially join the National Security Bureau's operations team.
