The Heavenly Master Becomes the True Heiress's Younger Sister [Metaphysics]

Shi Yan, a renowned celestial master of the Great Xia Dynasty, diligently cultivated her powers until she had accumulated enough merit to ascend. But in the blink of an eye, she transmigrated into a wealthy-family novel about the real and fake heiresses, becoming... the real heiress's younger sister. In the book, the real heiress returned reborn, full of resentment and determined to latch onto powerful allies while crushing the fake heiress. The fake heiress had the advantage and had perfected her innocent, fragile act, refusing to give an inch. Their two fiances, a domineering CEO down on his luck and blind, and the eldest brother of the wealthy family were also caught up in an endless tangle of grudges. The real heiress's younger sister was merely a background character. She died unexpectedly midway through the story, causing a misunderstanding among the others before fading completely into obscurity. Shi Yan had lived a hard life in her previous life. Now, watching these people squabble, she earnestly told her wealthy parents, "My brother and sister are both unreliable. I'll sacrifice a little and inherit the family business." Her parents: "..." The quarreling siblings: "?!!!" * On the first day Shi Yan took over the family business, her eldest brother shook his head. "Mom and Dad have lost their minds. Our little sister hasn't even graduated from college. How could she know how to run a company? It'll be in trouble within three months." The very next day, a client came to thank her profusely and brought an order worth tens of millions. "Celestial Master Shi, just do it your way. Our company will take whatever you make! It's just that a friend of mine seems to have encountered a ghost lately. Could you take a look..." Her eldest brother: "..." The real heiress, who only wanted to latch onto powerful people and put the fake heiress down, scoffed. "What's so impressive about that? Once my powerful patron gets his eyesight back, who will dare cross me?" Later, the blind big shot came to her of his own accord. "I'd like to ask Celestial Master Shi to take a look at me." The real heiress: "?" The fake heiress simply took out all her savings. "You're so powerful. Surely you can make him love only me for the rest of his life?" Shi Yan: "...I don't want to talk to someone who's blinded by love." Then she went out. She still had to exorcise a ghost for the owner of a partner company today. * In the end, as they looked at the family business, now several times larger, the Shi parents kept urging her, "Honey, didn't we agree you'd inherit the family business? We've given you the shares, so hurry up and go to work." Shi Yan wore an indescribable expression. "...I regret it a little. I accidentally made it too big. Being a domineering CEO is exhausting. I've decided to retire early." Her eldest brother, the real heiress, and the fake heiress, all working for her, cried, "We're the ones who are exhausted!" Who could have guessed that the unremarkable younger sister was a celestial master? She went out with someone, and a pile of orders came in when she got back. She sat at home, and big shots came knocking. They even had no shortage of talented people. And then there were the three of them... They'd been blinded by love for a while and wound up deep in debt, so now they had to work for her. Theme: Being strong yourself is the best!
