* Metaphor: A metaphor is a figure of speech where a word or phrase is used to refer to something it isn't literally, but has a similar quality. It's a direct comparison, not a literal one.
* "Replace you with million rings" is a literal statement. It implies physically replacing a person with millions of rings. This doesn't create a comparison or convey an abstract concept.
It's possible that the phrase is part of a larger context where it could be interpreted as a metaphor. For example, if someone is saying they'd rather have "a million rings" (representing wealth or power) than a person, then it could be seen as a metaphor for valuing material possessions over human connection.
However, without context, "replace you with million rings" is just a literal statement.
