The protagonist is set to be Shen Lian, a low-level guard in uniform. He grows from a young captain to a responsible hero. The growth line must be delicate, and he must experience the conflict between trust and betrayal, ideals and reality. It is necessary to set up multiple clues: the main line is to thwart the conspiracy of the court (such as powerful ministers colluding with foreign enemies), and the sub-line includes the mystery of the protagonist's life experience (such as his father's unjust case), the entanglement with Jianghu forces (the confrontation between the righteous sect and the villain organization), and the personal emotional line (the bond with Jianghu women or the daughters of upright officials).
