How many volumes of Overlord's novels had been published?

The seventh volume of the comic Douluo Continent had already been published.

I'm not very clear about the specific publishing situation of Battle Through the Heavens because I'm just a fan of online literature and can't get the latest publishing information. But generally speaking, the number of comic books published was different from the number of single copies. If you are referring to the number of standalone volumes of Battle Through the Heavens, then there is currently no official standalone volume of Battle Through the Heavens.

As of now, quite a few. But the exact number keeps changing as new ones come out.

Gosick's novel was currently in its sixteenth volume.

The fourth volume of Fei Dan's Physical Book of Arria had been published.

Xia Da's " Long Song Journey " had a total of three volumes.

The fourth volume had already been published on Douluo Continent.

Four volumes had been published on the Douluo Continent.
