Ma Lin had his own residence in Central Heaven City, right inside the Adventure Temple.
As the high priest of the Adventure Deity's Egg, he had to meet with adventurers on a regular basis, including gods, demons, and humans.
That's how races were categorized in Central Heaven City.
Humanoid beings like Cat People and Rabbit People, who were not born with demonic powers, were also classified as humans, and typically had to learn extraordinary powers later in life.
He had to hold ceremonies regularly, listen to the adventurers' opinions and prayers, provide blessings to adventurers around the world, and carry out various construction projects for facilities.
The addition of facilities to the Adventure Temple in Central Heaven City meant that temples located in other regions could also enhance their practical functions.
For example, people in the surrounding area could use some basic adventure magic.
