not really, like if I remember correctly it vaguely speaks of what happens to the protagonist from the first story (what is said is pretty much expected) and aside from that all three of the Soul Land Manhwa stories are seperate by a huge year gap and could be pretty much called indipendent from each other (aside from being in the same universe and all the protagonists being from the Tang sect)
No, some minor spoilers but barely any at all. Like you can read all series as stand alones that’s how little they’re actually connected. Though reading all will give you more of a background (obviously, like the Tang sect - how it appeared).
I want to finish CB1 but waiting for it to finish but does not look like its happening anytime soon.
Read the LN and it’ll go faster :p
Is the LN finished could finish the manga and then switch to novel.
OG is finished, translated I don’t really know
Will i get really big spoilers if i finish this before the first one??
