"Director Zhang, I agree to participate in this undercover mission." The voice on the other end of the phone was very serious: "Have you really thought about it? This mission is top secret. After joining, your files will be hidden. You will not be able to return to Jiangcheng for at least five years, and your family and friends will not be able to find you." "My parents are dead long ago, and I have no friends. Someone who is suitable to participate in this mission. You know, I have always wanted to activate my father's alarm. Please let me participate." After a while, Director Zhang sighed, "Don't you have a brother who has been taking care of you? But since you have already thought about it, I won't persuade you. You still have one month to take care of your family affairs."
