This Transmigrated Uncle and Cousin-in-Law Has Quite a Few Relatives

The Great Wei era, during the Huanxi reign.

Jiang Yunfan, who transmigrated there, has power, status, good looks, plenty of money, and a wealth of knowledge.

There's not much else he can boast about.

Unless he wants to brag about his grandfather, Jiang Chongshan, Duke of Great Pillar, and the fifteen husbands who married into the Jiang family:

His seven aunts' husbands and his eight cousins' husbands.
