Based on this image, It looks like the next chapter will still continue the flashback. I wonder if any other interesting revelations will be revealed in this flashback. Maybe Brook will unveil some information about the Vinsmoke family? If you remember in chapter 813, Brook knew about the Vinsmoke family.
More spoilers should be released later tonight, so I’ll be sure to add those as well
