The adjutant of the Second Staff Officer called just now and asked if Ling Lan had arrived. It looked like Ling Lan had gained the attention of the higher authorities. He would have a bright future ahead of him. The colonel thought to himself. He started treating Ling Lan and her friends better.
In order to become an officer at the staff officer department, you are required to be smart and know what are your superiors' intention. Hence, the colonel knew that Ling Lan was going to be promoted and wouldn't do anything stupid such as offending her. He stopped what he was doing and brought Ling Lan to meet the Second Staff Officer. Since his superior was in such a hurry, he didn't dare to waste any time.
As for the other five members of Lingtian, they didn't have the right to come. The Second Staff Officer only asked for Ling Lan. They were brought to the side and waited there for Ling Lan.
