The urban mercenary system is a function of the City Lord seal. It allows city lord to hire mercenaries from other cities. Moreover, if the City of Hope is successfully established, a Mercenary Hall can be created. Song Jian will also be able to open his unique mercenaries through the Mercenary Hall, to be employed by other city lords.
It's worth mentioning that this hiring system only exists between city lords, and other people can't see it. Only those who own a City Lord seal can use this function.
Many city lords, who are not strong, like to hire powerful mercenaries, either to fight monsters and level up for themselves or to ensure their protection. The cost is just some insignificant Doomsday Coins.
Song Jian clicked to hire city mercenaries, then swiftly started searching through the mercenary list.
