Into The Deepest, Most Unknowable Dungeon Vol 7

Thing sure hit the road quick. Volume 7 and we're slowly starting to see each country technological development. One gies further than ever, while the other slowly stagnanted and completely feel cut off. The jumping of perspective does help show where each groups are currently located and what each groups are doing at the time. This jumping will probably become a big play in the future volumes where the plot finally reach mid way towards what to be expected of two countries being enemies.
