The Oldest Disciple: Farming Intimacy to Become Immortal

At the age of seventy-eight, facing imminent death and lacking any significant accomplishments, Li Meng discovers a System that transmutes intimacy into immortality. Lacking aptitude for traditional cultivation methods like meditation or swordsmanship, he finds his ultimate advantage within the notorious Joyous Union Sect. The System's core mechanic allows him to convert physical contact with female cultivators into experience points: holding hands yields ten EXP, a passionate kiss grants one hundred EXP, and dual cultivation, reaching its culmination, leads to a level-up. Understanding his unique opportunity, Li Meng abandons his pride for survival. He cultivates a facade of a harmless, benevolent "Grandpa" to disarm the sect's alluring yet formidable female cultivators. To the outside world, he is the charitable "Wealth-Scattering Senior Brother," but in truth, he is a shrewd strategist seeking his next cultivation fuel. Li Meng will aid everyone from the proud Senior Aunt to the innocent Junior Sister, with each problem solved demanding a night of "cultivation" in return. This story features a unique, manipulative elder protagonist, clear system progression including alchemy and talisman crafting, and harem building as the protagonist rises from weakness to supreme power.
