Infinite Double-Stacking Super Evolution Cultivation System

[Slaughter and domination, crushing all opposition!] “Ding! You threw one punch and gained 100 x 2 experience points.” “Ding! You threw twenty punches and gained 100 x 1,024 experience points!” The Pine Crane Longevity Fist advanced to a top-tier technique, and his cultivation rose from the second level of the Body Tempering Realm to the fifth! With a System that can double anything without limit and evolve techniques, one punch doubles your gains, and twenty punches multiply them twentyfold. There is no cap, just endless doubling. Your cultivation can reach the peak of the Body Tempering Realm in no time. Why spend thousands or tens of thousands of years cultivating to achieve immortality, exhausting yourself and worrying about being struck by lightning? With my doubling System, I can become an immortal just like that!
