In case you haven’t read yet, you may want to check out the previous post about Heroic Death System here where I talked about my general thoughts about the novel. Meanwhile, this post contains my thoughts about the individual worlds in the series.
Heroic Death System has 16 worlds (17 if you include the last known reincarnation cycle), 10 of which have redo arcs. Redo arcs have a chapter showing what happened once Shang Ke died and the rest is when he has a second chance to do the world.
