I want to create a rule that operates on the results of a specific rule.

[원동찬]

There is a Task in a specific Epic, and there is a Sub-Task under that Task. When a sub-task changes to the in-progress state, I want both the task and the epic to change to the in-progress state. Task works, but Epic doesn't change. Help me.

Hi @원동찬  - Welcome to the Atlassian Community!

You will need two different rules for that. One for the Sub-task changing to In Progress. You should include a Condition for Issue Type = Sub-task for the Issue Transitioned trigger. 

Then copy that rule and change the Condition for Issue Type = Story. Be sure to click the box of this second rule on the Rule Details page to allow other rules to trigger this one.
