I Have Countless Skills, but I Just Want to Be a Villain Swordsman

If I am not the protagonist, but a villain, how can I survive in the world of cultivating immortals? If I want to help a woman break off her engagement, what should I do? If I am very powerful, but outsiders see me as just a grasshopper that can be crushed to death, how will I respond as a villain? If the master who valued my talent only wanted to take away my talent, how could I, as a villain, resist? If the sect is being invaded by the Demon Sect and the Demon Sect invites me to join, how will I make a choice as a villain? I have countless immortal cultivation techniques, but I only like "sword"! A man with a "sword" is invincible!
