Xu Fan finally had a period of leisure, free from disturbances and living a peaceful life.
During this time, he taught the security team the "Xuan Yi Battle Technique".

It's worth mentioning that in the past few days, Zhou Xian had invited another group of former comrades-in-arms to Zhonghai. After formal interviews and strict assessments, most of them qualified to stay as reserves for the security team, adding up to about thirty people.
