Please, Invincible Disciple, Leave the Master Immediately

Master knelt down and begged me to come down from the mountain: "Disciple, you are so unfaithful. Come down from the mountain and harm others!" I am born invincible, but ignorant and simple. After coming down the mountain, five stunning senior sisters took turns pampering me: the senior sister fed me, the second senior sister provided training, the third senior sister gave me money, the fourth senior sister gave me poison as snacks, and the fifth senior sister used formations to build a playground for me. I wanted to live a low-key life, but trouble kept coming. It doesn't matter, whoever bullies senior sister, I will solve it with one finger. This is the story of an invincible junior brother who is doted on by his senior sisters.
