Shou Yuan Lu: Cut Off the Longevity of the World and Write Down the Road to Longevity

Ye Po, a young man from modern times, traveled to the world of immortality and inhabited the body of a fourteen-year-old civilian boy. He is gifted with a photographic memory, but due to his low status, he can only survive in troubled times. The gears of destiny turned quietly when he awakened the "Shouyuanlu" system - whenever he killed any life with his own hands, whether it was a monster, a mortal, or even a mouse, he could convert the other person's remaining lifespan into a "Shouyuan Container". These lifespans cannot directly increase lifespan, but can be used to "simulate practice" of any skill, but the rules are strict: you must wait for the skill to be introduced before you can use the lifespan container to speed up the practice; the consumption year is determined by the protagonist, but the system will automatically adjust the lifespan consumption efficiency according to the level of the skill - the more advanced the skill, the slower the lifespan consumption, as if the world itself is suppressing the protagonist's arrogance.
