My Lucky Junior Sister Exorcises Demons and Becomes a Supernatural Prodigy

[Mysticism, exorcisms, lucky charm, romance, mild horror] The little junior sister of the Mystic Sect has gone down the mountain with her three senior brothers to gain experience~ When she received her master's task, “Do a hundred good deeds and ease a hundred worries,” she was completely stumped. What should she do? What should she do? She has no talent for subduing ghosts or dispelling evil. She knows next to nothing about past lives and matchmaking. She has a little knowledge of Four Pillars astrology, and only a vague understanding of feng shui and choosing auspicious locations. It's okay, it's okay! The little junior sister is an extraordinarily lucky girl with innate spiritual talent. After going down the mountain, she first encountered a curse cast by a black wizard. The second time, the four disciples joined forces to subdue the Gates of Hell. The third time, she ran into a golden python that had failed its tribulation. The fourth time, she broke a sticky curse involving the Gu “Blood Earthworm.” The fifth time... Along the way, the little junior sister not only fought monsters and leveled up, but also regained memories of her past life and found her destined love from that life. In her previous life, the little junior sister was a princess who fell in love with a eunuch of the highest rank. They say it was unrequited, too. Tsk, tsk, tsk... The two had agreed to continue their romance in this life, but the eunuch of the highest rank changed his heart, and then her eldest senior brother came along and complicated things. P.S. The main storyline follows the four disciples of the Mystic Sect as they exorcise demons and vanquish evil, while the little junior sister's relationships with her three senior brothers form the subplot.
