In the seventeenth year of the Republic of China, Gu Mingshan, the governor of the three eastern provinces, died suddenly in his study. Overnight, the handsome manor was turned upside down.
The eldest son Gu Jinghuai, twenty-three years old, has a cold face and an iron fist. He took over the power surrounded by wolves. While stabilizing the morale of the army, he secretly guarded against his father's sworn brother Zhang Dehai who was about to make a move. The second son, Gu Jingyu, is a fierce and reckless man with a hard mouth but a soft heart. He was beaten since he was a child and grew up. He is the sharpest and most untamable knife in the eldest brother's hand.
Just as the commander-in-chief was holding a funeral, a twelve-year-old boy from Huzhou, more than two thousand miles away, came to the door alone. His name is Gu Xingci, and he is the illegitimate son of the warlord and an opera singer. Before her death, his mother left a suicide note, asking him to take an old jade pendant and go north to recognize his father. But when he got to the door, he learned that his father was dead.
From the first day he stepped into the handsome man's house, this young man, who was as thin as a bamboo pole and too good-looking, was involved in a world he had never seen before: strict family laws, the calm discipline of his eldest brother, the unruly care of his second brother, the secret protection of his sister-in-law, and the undercurrent of the power game inside and outside the handsome man's house.
Zhang Dehai stared at him, wanting to make a fuss out of him. Gu Jinghuai protected him and polished him with rules. And he himself, in this strange family, had to learn not only how to write, read, and deal with others - but also how to straighten his back and be an upright family man.
An illegitimate son, a military mansion, a group of people with their own thoughts. In troubled times, blood is both a passport and a weakness.
