Which Chapter Overlord

Hi guys, I dont remember if it was light novel or webnovel
But apparently I read to the chapter where
Ainz already conquered E-Rantel
The Empire is also submitted to him

Then he traveled to the kindom of knights I think? I think it was southern kingdom or somethint I dont remember.

But long story short he had his frog guardian Demiurge Attack the kindom while he pretend to be the savior to help them.
I read to the part where he is on his way to rescue(?) the second fort of that kindom that got taken by demons(?).
He walk to the castle gate and release a bunch of ghost to scare everything inside the fort.

I have been searching but I cant find either of them on webnovel and light novel.
They seems to be behind.

If someone is nice enough to explain if there is any difference or any turning point whereas light novel took a different turn compare to webnovel, illl be grateful.

I want to try reading both versions if I have time.

Thanks

Edit: no im not a bot

 

Doubt

 

That's the anime.
... Look around volume 7,8-ish?

 

I didn't read the WN, but in the LN, what you're describing is in volumes 12-13 (those two volumes cover the same arc.)

 

LN 12 iirc
Neia baraja is there right?

 

LN almost totally differ from the WN, especially albedo's existance

 

Should be the light novel volume 12/13, where he helps the holy kingdom, they are paladins not knights.

 

Thanks guys
