Referring to previous literature review
I would suggest that you include the work you have read, as well as the works that the other papers mention. The purpose of the literature review in a paper is to describe related pieces of work, and showcase how your work complements, surpasses and stands out. This strengthens the narrative of your research and helps the reader understand what makes your paper valuable, compared to other approaches. In order to achieve that and build a more complete image, you need to include as many related papers as you can find and study in the literature review part.
