Ever since I was a child, when I heard my grandmother tell about legends, I had the desire to become a legend. Legends not only have extraordinary powers and talents, but they also use them to help people. They are great and kind people in my heart. So if I could become a legend, I would do the same. I want to use my talents to help those who need my help, and I need the power of a legend to make it easier and more meaningful.

Vì yêu cầu của đề là trả lời dài nên mình trả lời gián tiếp nhaa. Nếu tóm tắt thì sẽ là như này:

I want to become a lengend because I want to help everyone.
