It’s about a swordswoman whose student is captured, so she goes to rescue her.

I was left paralyzed with only a month to live, but that “9-inch” part of me was still hard as a rock. Even the sickly beautiful schoolgirl couldn't resist my “pecker,” and to fulfill my dying wish, my sister even dressed up as a lady in black stockings to teach me how to “drill.” What's more outrageous, the hospital nurses wanted to make a little movie with me, lining up with the head nurse at the front...Just after coming out of the emergency room, I saw the system panel:Name: Ethan JonesGender: MaleLength: 9 inchesSkill: Hard as a Rock LV1Note: Peak human hardnessDying Wish: To caress auntie's sheer black stockingsTask Reward Points: 1000 pointsDespite my strength and stamina attributes being only at 1, and my agility at 0, only my “pecker” could lift the heavy blanket while doing squats.
