I Want to Spend My Life to Become a Great Swordsman

Xuan can't change his fault, but Krypton can change his life! This is the world of immortal training and cultivation Whether it's mounting chips, customizing exercises, visualizing data... Or more powerful spiritual root implantation, spiritual body transformation, magic weapon breeding... It's all available! I don't have spiritual source points for the time being, but I have the "Great Sword Immortal Development System"... But it's just a matter of krypton life. The embers of ancient immortal cultivators, the modern evil lunatic... Let me kill them all with one sword! Wait, what did you just say? What do you mean, why do I only care about my own life?
