A new child in the Hou Mansion: The Jingbei Hou Mansion welcomes the birth of its youngest son, Yun Zhao, after having two sons. The Marquis Yun Chong personally named his beloved son "Zhao", which means "upright and upright" and has different expectations from his two elder brothers.
Deep brotherhood: the eldest son Yun Lin (16 years old) is serious and self-disciplined, while the second son Yun Huan (10 years old) is lively and active. In sharp contrast to the younger brother Yun Zhao, they have cultivated a deep brotherhood through daily martial arts practice and reading.
Strict father and loving mother: Although the Marquis of Jingbei guards the border all year round, he strictly supervises the studies of his three sons through letters; Mrs. Su, the Marquis of Marquis, maintains the family with gentleness, and the younger sister Yunrou (5 years old) is the darling of the family.
Crisis is coming: The Northern Canglang Tribe invades on a large scale. The Marquis of Jingbei and his eldest son are trapped in Shuofang City. The second son is seriously injured and sent back. The family faces an existential crisis.
Accepting orders at the critical moment: With the support of the old marquis, 14-year-old Yun Zhao refused to flee south with his mother, and decided to sell his property and recruit volunteers to go north to rescue his father and brother.
