At the same time, each grade is divided into a chief and a deputy. The chief's breastplate has two vertical lines, while the deputy's breastplate has only one vertical line.

Vice President Tan, who attended the class that day, had an iron sign standing upright, while Chao Jiang, the director of the grassroots security office, had a lead sign standing upright.

According to Xu Shu's understanding, Chao Jiang is a principal, Vice President Tan is a deputy, and Duan Kuohai must be a principal.

After doing this, he was in awe.

No matter what year or where in the world, Duan Kuohai is definitely a powerful figure in the grassroots system.

Xu Shu calmed down and said, "How many people do we have in our ninth team?"

Duan Kuohai said, "The ninth team is newly established. Currently there are only two people, Xiao Qin and me, one captain and one vice-captain."

Xu Shu looked at Duan Kuohai in disbelief, "You two officers are in love, but I am a soldier?"

Duan Kuohai waved his hand, "Don't be so confident. It's not sure whether you are a good soldier or not. Okay, let's not talk about anything else. Don't you want to learn some small grappling skills? Then come on..."

Duan Kuohai carried out a wooden man as tall as one person from the east wing, with his feet inserted into a black chassis.

The chassis is filled with sand to form a tumbler structure.

There are many acupuncture points and meridians marked on the wooden man's body. This object was Duan Kuohai's earlier practice tool.

At that moment, Duan Kuohai used this wooden dummy to tell Xu Shu about the bones, joints, meridians, and acupuncture points of the human body.

Xu Shu concentrated his attention, and the extraordinary attributes of the bachelor immediately showed their beauty.
