"A commander ranking battle?" Many faces in the crowd turned at the announcement.
A commander ranking battle was similar to a seizing residence battle, both were methods of shifting power.
The challenger's rank must be lower than the person they challenged, and if they succeeded, the ranks of both opponents would be swapped.
For example, the lowest-ranking commander could challenge one with a titled rank, and if they won, the challenger would take the title along with associated privileges, resources and status.
If one of Commander Li Chengfeng's commanders defeated Shen Zhui, the title of army protector would go to the victor. This was a challenge accepted even by the Sky Heart Hall.
Like the seizing residence battle, the commander-ranking battle ignored life or death!
The only difference was that a formal challenge between commanders was only allowed to be challenged or given once a year.
"This doesn't bode well..." Some of the crowd murmured.
