Isn't This Right? How Come I Was Reincarnated into the World of Cultivating Immortals?

I was an ordinary student in the 21st century. Why was I reincarnated into the world of cultivation? Okay, will I become the strongest in the sect after I accept my destiny and become the eldest brother of the sect? Then I will do whatever I want hahahaha! But I obviously just want to live a leisurely senior brother life of bullying cats and dogs, so why are you chasing me! Then I can only bully you! If you can't beat me, then don't mess with me. You actually let me live a life of bullying cats and dogs, and harvesting treasures and beauties. You are so kind! Single heroine/invincible/daily/cool writing/funny
