The Carefree Little Shopkeeper: My Years of Winning My Wife's Heart in Ancient Times

(A lighthearted, funny slice-of-life story, not an invincible power fantasy.)

A 21st-century engineering student transmigrates to ancient times and becomes a poor scholar.

He even has a special space with him, containing a shop that sells adult products.

Watching everyone head off to the pleasure quarters to listen to music, Li An makes a grand vow to open a shop selling adult products in every corner of the Wu Dynasty.

"I'll bring a richer sex life to the people of ancient times. I, Li An, won't shirk my duty."
