After the seniors left, the remaining people were divided into three groups.
The Mercenary Corps had the fewest members. They could choose to follow the United Corps or take on mercenary tasks in a medium-sized Abyssal Plane.
Members who chose the United Corps, like Cain, had relatively simple tasks.
As interns, they would go to a large Abyssal Plane, participate in the corps' defense and rotation, and also have patrol duties.
Cain was heading to the Twelfth Abyssal Plane, which had a casualty rate of less than 5% in the past decade and a death rate of less than one in ten thousand.
The last death in the Twelfth Abyssal Plane occurred two years ago.
Cause of death: Died of old age.
Before heading to the Abyssal Plane, Mike and others had attended professional classes introducing the Abyssal Plane.
The Abyssal Plane is broadly divided into three types: large, medium, and small/micro.
