Lin Rui led the newly promoted special forces team and experienced the test of life and death in thrilling international missions. They have grown from novice special forces to elite sharp knives. The team members have different personalities but advance and retreat together, with humor and passion coexisting. The three volumes cover everything from recruit training to international counter-terrorism, to uncovering the truth behind Lin Rui's father's disappearance and the ultimate enemy showdown. Each volume completes the main task independently, but echoes each other, step by step revealing the conspiracy of the world and the inner growth of team members, and ultimately achieves self-breakthrough and the protection of family and country beliefs.
