The Uzumaki manga is not overly long or short. It's just the right length to immerse you in its creepy world. The number of volumes and pages can change based on the format you come across.
I have uploaded chapters 124 - 153 of the Ringbearer manga to the attachment. You can download and view it. Please note that this manga only contains 153 chapters because 124 chapters have not been released yet.
Chapter 7 of a manga can contain a variety of elements. It might show the protagonist facing a major challenge, or it could introduce a new location or magical power. Without more details about the manga, it's hard to be more specific.
It depends on the specific manga. Different manga have different plots and events in chapter 8. Maybe it's a key turning point or just a continuation of the story.
