What Kind of Counterattack in Old Age, I Am Clearly the Supreme Genius of My Youth

Su Mu, a disciple of Shushan, was reborn at the age of eighteen, but awakened an old age counterattack system. [You have been plotted by a traitor, your foundation has been damaged, you have practiced hard for five hundred years and still have no hope of achieving elixir, your sect has been destroyed, your enemies are rampant, and your life is approaching, how can you be willing to end it like this? Thirty years of Hedong, thirty years of Hexi, don't bully the old and poor, counterattack! [If you want to counterattack, you must have the courage and determination to break through and then stand up] [Please abolish your cultivation within three days to obtain the talent [Innate Sword Bone]...] Su Mu looked at his severely injured and broken Dantian and fell silent. Didn't this system come at the wrong time? The next moment, the system prompts that the task is completed and the reward has been received... Great system, you came at the right time! What kind of counterattack in old age, in this life, I am the unparalleled genius!
