Explanation
The pattern ていく attaches to the て-form of a verb (or other compatible forms) to show that an action or change will continue from the present into the future, or that movement/transition happens away from the speaker. It often conveys a sense of gradual change, ongoing effort, or progression. It contrasts with てくる, which focuses more on actions moving toward the present or toward the speaker.
