Kill Me to Preach? I Carry My Sword and Kill Through the Fairy World

[Cultivation of Immortality + Strong Female + Revenge] There is a blood feud and the law of heaven is unfair! In this case, I will lift up the sky and bury this immortal path! * Chang Huan spent all his money to support the number one scholar from a poor family, and waited happily until he got married, but in return he was slaughtered by his entire family and shot through the heart with an arrow! It was only after her death that she found out that her husband was actually the Son of Heaven who had come down to earth to endure calamities, and the fate of her whole family was just a game of love and calamity between the Son of Heaven and the noble daughter of the Immortal Sect! She climbed through the cloud ladder where ghosts and souls devour souls, and broke into the Nine Heavens Immortal Gate to seek justice, but she only got one sentence in exchange - "A mere mortal who has spent decades living at the snap of his fingers is bound to die anyway. Why should he care so much?" What's even more ridiculous is that they actually want her to be the enemy's dog, euphemistically calling her "compassionate"! What a compassionate celestial being! Chang Huan laughs wildly and hates the sky! Since the way of heaven is unfair and the way of immortality is ruthless—— Then she becomes a demon! Kill gods! You regard me as an ant, so I will let Jiuxiao fall into purgatory forever!
