What's Wrong with the Little Wife Who Comes to Visit and Knows Hundreds of Millions of Points of Metaphysics?

[Metaphysics + fortune telling + ghost catching + sand sculpture + cool writing] After her grandfather passed away, the 18-year-old metaphysics genius Lu Yao had to follow her grandfather's last wish and travel to the faraway city H to find her fiancé. Along the way, ghosts who sensed her different abilities stalked her and chased her. Ah Piaojia was unwilling to give up, "Master, my son will take the college entrance examination soon, can you give me a message for him?" Ah Piao Yi was worried, "Master, my death really has nothing to do with my wife!" Ah Piao Bing cried, "Master... My family never comes to see me?" Lu Yao shrugged upon hearing this, "... Help me find my fiancé first." After a while, the painting style suddenly changed. Ah Piao Jia clung to the window and peered in: "Master, look, there seems to be a man sitting in your fiancé's arms..." Ah Piao Yi was startled: "Master! That man is even more handsome than your fiancé!" As a result, the fiancé was not that easy to recognize at all. He turned out to be a popular idol and had many illegitimate meals. Mu Jinghan blocked her in the dressing room and put her in his arms, "He said you are not an illegitimate wife. You keep peeking at me. Aren't you trying to throw yourself into my arms?" "Don't think wrongly, I'm not an illegitimate lover, I'm your fiancée!" "Oh?" The man seemed dissatisfied and leaned into his ear with a seductive voice, "... It's a beautiful thought. Why didn't I know that I have such a beautiful fiancée?" Chu Yao: "Ask your mother! If you don't believe me, ask your mother!!!" Wait... What kind of tiger-wolf talk is this? (The genius metaphysics girl vs. The popular idol, the doting wife and the maniac, the plot of marrying first and loving the master later, interspersed with multiple metaphysical stories)
