Li Jianmin had just turned sixty and retired. Living on his meager pension, he opened a general store in a bustling metropolis, only for local thugs to smash it up and humiliate him. On the brink of death, he became bound to the Peerless Shopkeeper System. As long as he fulfilled the needs of special female customers and looked after them well, he could not only obtain supreme cultivation techniques, but also grow one year younger!
On the very first day, an ice-cold Valkyrie, gravely injured, collapsed at the shop entrance. A bowl of specially made instant noodles helped her break through, and Li Jianmin instantly returned to the age of fifty-nine. With a casual slap, he turned the powerful scion chasing her into a cloud of blood mist, leaving the Valkyrie stunned on the spot.
From then on, a cool campus beauty, an unparalleled female CEO, and an imperial female commander all lined up to seek his guidance at the shabby little shop. As Li Jianmin went from an old man to a forty-year-old uncle, then back to an invincible, peak-condition twenty-year-old war god, the entire high-martial-arts world and the wealthy families panicked: Who exactly was that immortal old man who blew a ninth-rank demon king apart with one punch?!
