That was the task given by Wilkes and Devon. Each mission location is different (namely, snowman, helmet, Marcus, Dugu City, Rift Valley City), and each city can receive a special mission after completing five or six missions. So far, four special missions have been completed. The task to trigger the new official to take office is to become a master thief, and then hold a ceremony, after which he can change his clothes (especially remind the novice thief guild to change clothes, otherwise the final ceremony will be held).
