Creating a story based on my long texts.

Hello. What should I do to make chatgpt able to create a story based on my text and its continuation based on my added texts and what happened in previous threads? Unfortunately, adding text in the style remember text 1,2,3 etc. does not work because it forgets what was in the text in the earlier texts I added. Of course, I realize that Chatgpt has some limitations in the length of the text, so I break them into shorter ones. Is it possible to make chatgpt remember all the texts and later write a story from them and continue based on the remembered texts?
