Integrating RSS into Multiple WP Blogs

I am sure that this issue has been covered before, but I can’t seem to find exactly what I need.

I am very new to the WP package and I need detailed instruction on how to take the info generated by https://myblog.domain.com/wp-rss.php and include it in https://myotherblog.otherdomain.com.

I need to know what codes or plugins are needed to inseert that RSS produced content into the articles on other blogs.

Thanks in advance for the help.
