What is the rhetorical device of calling? Give me an example to answer it!

Calling is a rhetorical way to address people or things directly in writing. That is to say, call directly to the person or thing that is not in front of you and talk to him (it).

example: ah! Electricity! You are the sharpest sword in the universe! My sword has been pulled out, but you, you can pull out my tangible sword, you can't pull out my invisible sword. On "Qu Yuan" ljbblkoohl; Benjamin; 557.1595
