A family of widows, all shouldered, raising the dragon flag!

He transmigrated into the body of Qin Ze, the ninth young master of the Zhenbei Prince's Mansion in the Great Zhou Dynasty. Born with a mortal body and weak martial arts, he was a troublemaker despised by everyone in the imperial city!
His father and brother were ambushed and their entire army was wiped out. The Prince's Mansion was in turmoil. Yet, while the mourning hall was still open, he secretly hid with the top courtesan of the Wan Hua Lou, indulging in a life of debauchery!
He thought he was going to be abandoned by his family, but to his surprise, his grandmother made him take on the heavy responsibility of the Qin family's eighth branch!
"A good-for-nothing like you dares to lead the Qin family? You'll have to get past me first!"
"You can't talk about ice with a summer insect; trash is trash!"
"I refuse!"
"I don't want to either!"
Facing eight widowed sisters-in-law with distinct personalities, and also the watchful eyes of external enemies in the imperial court!
I, Qin Ze, will shoulder this responsibility!
Shouldering the heavy burden of the family!
May it branch out and flourish!
Continue the family line!
