After Losing Everything, I Became the Greatest of the Immortal Path

[Leveling Up + Strong Female Lead + No CP + Slow Burn + Lots of Original Worldbuilding] Lu Shaoheng comes from a privileged family. She's exceptionally talented, surrounded by loving friends and family, and engaged to a man she loves. Raised to be spoiled and willful, she thinks life is always easy. Only when it is all taken from her with ruthless ease does she realize, to her shock, that her life is nothing but a clichéd story? Her life falls to rock bottom, and a divine voice rings out. [Life is a play, and you are fated to be Jiang Yunjiang's foil, a clown forever. But now you can choose to return to the past and turn the tables.] [When you go back to the beginning, you can give everything to Jiang Yunjiang in exchange for a decent future. Or you can make a new plan and fight her again.] A fresh start! What a wonderful opportunity! But... "I've never regretted anything, so why would I start over?" She doesn't look back. She only moves forward. Beyond her bitterness and resentment, Shaoheng finally realizes that power is the foundation of all rules. Ambition awakens in her bones, and desire spreads like wildfire. Mountains may weather and change, rivers may reverse their course, but she will always move forward! Why ask how many years it takes to cultivate? When Shaoheng finally looks back, she has gone from taking her first steps on the path to immortality to claiming the top spot on the Fengming Ranking, rising straight to the clouds and slaying immortals with her sword. By now, her journey has made her the most admired leader of the immortal path in all the world. [Warning: The melodramatic plot has a reason behind it, and the answer is given very early on. It also takes up very little of the story. Most of the novel is cultivation.] [The heroine is not a paragon of virtue, and her moral standards are low.]
