A Family of Loyal Heroes: Grandmother Orders Me to Protect My Sixth Sister-in-Law

I transmigrated as the only heir of the Duke Who Guards the Nation’s household in the Great An Dynasty, but it was hell-level difficulty from the start!

My father and six brothers died in battle, leaving the 300,000-strong Lin Army without a leader and drawing covetous eyes from every direction.

The emperor pretended to console me, but in truth arranged for me to marry the Sixth Princess. The six sisters-in-law were included too, while six major court factions stood behind the arrangement, all eyeing the Lin family’s military power.

In the ancestral hall, the family was battered by storms on every side.

The Old Madam threatened a military coup with an army of 300,000 and forced me to follow the tradition of a younger brother marrying his elder brother’s widow, taking all six sisters-in-law as wives!

I thought I’d been trapped in a puppet’s game with no chance of survival, but luckily I awakened a unique divine skill: [One Loyalty Card a Day].

If the check succeeds, the target instantly becomes utterly loyal and will never betray me!

If it fails, the instant-death mechanism activates, and I die on the spot!

So by day, I’m a top-tier wastrel, indulging in wine and women and being wrapped around my sisters-in-law’s fingers.

By night, I’m the Grim Reaper of the dark, wielding the power of life and death, able to kill even a grandmaster with a single glare!

“Eldest sister-in-law, you wouldn’t want the secrets of your family being exposed, would you?”

“Your Highness, you want me to break off the engagement? That’ll cost you extra!”

Several years later.

Just as the emperor thought he had drained the Lin family’s resources and prepared to move in for the kill, he was horrified to discover...

The entire court and even enemy generals were all loyal to Lin Xiao!

With the princess in his arms, Lin Xiao sat on the imperial throne and gazed down at the assembled officials with a smile.

“Your Majesty, you wouldn’t want the Great An realm to bear the Lin name from this day on, would you?”
