World view: An imaginary world in troubled times. In the bitter cold land in the north, the feudal lords are divided. This is an era where martial arts and power are equally important. The border is full of chaos and the undercurrents in the court are turbulent.
● Protagonist Lin Hu: The adopted son of the Tianbei Prince's Palace and the commander-in-chief of the Snow Wolf Army. Known as the "Snow Tiger of the North", he is at the peak of his martial prowess and has an aloof and cold personality. Although he holds a large number of troops, due to his "adopted son" status, he has natural flaws in inheriting the throne of Tianbei. He is the most dangerous "stumbling block" in the eyes of the crown prince Lin Beifeng.
● Core conflict: The game between the powerful master and the orthodox bloodline. Lin Hu not only has to face powerful external enemies (such as the Beidao family), but also has to deal with the temptations and fears of the prince Lin Beifeng. He is in the dilemma of "being a powerful minister is suspected, being a loyal minister is wary".
● Key image: Snow Wolf Flag. It symbolizes the patron saint of the North and is also the totem of Lin Hu's power.
