In the setting of the "All Heavens," the barriers between worlds were extremely sturdy.
Aside from the All Heavens Transfer Station, an anomaly among anomalies, casually traversing between worlds was virtually impossible.
To accomplish such a thing, one had to pay a price that even a Ninth Order being could not bear.
The most typical example was Maha!
As the first-generation World Crosser of the transfer station, Maha had taken advantage of the station master's immaturity, before he had learned the capitalist's heartlessness, to scrape together enough money for his freedom. He then left the transfer station and gained his liberty.
However...
Even as a Ninth Order Transcendent, Maha had spent who knew how many years without finding a way to freely travel between other worlds!
Or rather, he had failed to find any method besides abandoning all his existing advantages and completely reincarnating into another world.
In the end, Maha had died horribly at Zhang Guangmu's hands while trying to trade with the station master for the so-called Traversal Key.
The difficulty of reaching into other worlds while ensuring one's own advantages was obvious.
Zhang Guangmu believed that even the All Heavens Transfer Station had paid a price to dispatch people to various worlds, however slight that price might be.
Otherwise, the station master would not have been so harsh toward the World Crossers, setting such severe punishments for mission failures.
This was called "cost shifting"—transferring the risks one ought to bear oneself onto the workers under one's command. It was probably a required course for every ugly capitalist.
Now that Zhang Guangmu had become the master of the Xuan Yan Realm, he instinctively sensed certain things—an item of privileged information.
After becoming a realm master, Zhang Guangmu had obtained an all-weather, omnidirectional protection from the World Will.
