"No need to rush, I still haven't grasped the combat level of this Bald, and it's safer to bring someone experienced in actual combat," Number 0 had made a comparison too.
In a month, if she wanted to successfully win a spot in the Personal Guard, she must possess strong combat abilities. The principle of adjusting military ranks is that each player gets one opportunity to adjust during Military Road Time. She doesn't intend to waste this opportunity so soon.
Upon reaching school level, Number 0 could very well use the opportunity to adjust back to Sergeant Level. Her skills wouldn't decrease, but the requirements for military merit would be lowered. Then she could easily masquerade as a Sergeant and dominate those school level players, playing the pig to eat the tiger.
After hearing Number 0's plan, clearly calculated to the last detail, Little Eight could only say one thing: (Number 0 is extremely cunning, a person who must have her revenge.)
