The market prices in each street district of the Outer City vary for various reasons.
In some districts, weapons are more expensive, in others, armor is pricier, and in yet others, medicines cost more...
This led to the emergence of a profession in the early days known as "street district trading guilds."
The main business was buying and reselling goods.
However, when teleportation gate costs increased, the profits from trading dwindled, leading to the gradual disappearance of this unique profession.
Some well-connected trading guilds could obtain teleportation discounts from familiar teleportation gate receptionists, allowing them to transport goods across districts more cheaply than others and forming businesses with similar operations dedicated to transporting goods across street districts.
The most prominent among them was Kangaroo Express, which Li Zheng had previously encountered.
