I've Stopped Being the Group's Pet, Junior Sister.

In the previous life, Fu Yu, the young master of Penglai Immortal Realm, although his father did not like him and had no teachers or friends, he had Tianling roots and was able to break through the Nascent Soul stage at a very young age, making him a leader in the world of immortality. With a good family background and high talent, Fuyu is simply the proud son of heaven. But—— On the day of her wedding to her glamorous elder brother, she was killed by a fellow disciple with a sword, and she died with her eyes open. After that, junior sister Lu Yao seemed to have cheated. She replaced Fu Yu and became the young master of the fairyland. Her cultivation level improved greatly and everyone favored her. Compared to Fu Yu, she was even worse. Fu Yu later found out that someone had helped his junior sister steal her luck and borrow her life, which resulted in Fu Yu's tragic death. * When he opened his eyes again, Fu Yu became the junior sister of the tenth Fang Sect, which ranked last in the world of immortal cultivation. The original owner's qualifications were extremely low. He had practiced for hundreds of years and could barely break through to the foundation-building stage. He was unable to fight back even if he was lightly hit. But the original owner was the darling of the entire Shifang Sect. Except for the senior brother with a sinister personality, no one from the head of the family to Sa Su's junior brother did not love her and pamper her. Fu Yu: Is this the legendary junior sister who is the favorite of the group? Later, when Fuyu relied on her own power to upgrade and fight monsters, kill Lu Yao who stole her life, and bloodbath Penglai Wonderland, allowing Shifang Sect to regain its former glory, countless people asked her if she had a favorite Taoist companion, hoping to become a god with her. Fu Yu smiled faintly at them: "Sorry, I specialize in the ruthless way." Under the bright moonlight, the man's cold fingertips touched the girl's face, with an unknown meaning: "I heard that you specialize in the ruthless way?" The young man's surly eyebrows widened: "What a coincidence, I specialize in the path of sentient beings."
