Qi Haoran was domineering and even a little childish. However, he was able to quickly gain the morale of the army. Other than his ability and personal charm, the most important thing was that he unconditionally accepted the veterans and injured soldiers that were eliminated from the various battalions.
Some of these soldiers nearly forgot where their hometown was. Many of them didn't have the courage to return to their hometowns, let alone those injured soldiers. If the troops were willing to let them stay, it was a way out for them. They were naturally extremely grateful to Qi Haoran, who accepted them unconditionally. Before Qi Haoran came, those injured soldiers didn't receive such treatment. Most of them were sent home after their wounds healed.
