The Mighty Substitute Bride

Pork butcher Wren Sterling is born with superhuman strength, and enters a substitute marriage to the paralyzed General Kael Lowe in place of her cousin. Facing a dilapidated household and hostile relatives, she uses her strength to fiercely protect her husband, evict bad relatives, collect debts, and assert her authority, growing from a street vendor to the famous owner of Lu's Braised Delicacies shop. Her husband Kael appears paralyzed, but is secretly gathering his old loyal troops. The powerful couple work together, rising from the bottom to become the respected lady of the general's household, eventually uncovering a military grain conspiracy, and are granted the titles of Imperial Lady of Honor and Duke of the Northern Garrison.
