Magi: the Labyrinth of Magic, where should I start in the manga?

I recently looked through Magi: the Labyrinth of Magic on Netflix for the second time, while searching the internet for a date of a third season, I read that it will most likely not be continued since the anime is not profitable. But since the manga is finished, I wonder from which volume I have to join in order to follow the story from where the anime ended.

The second season ends with volume 12, chapter 115

Thank you for your answer, but it can't be that the whole thing ends with volume 12, because on Amazon in the description of the 12 volume Judar is just in Sindria and has broken the barrier

The short description can never reproduce the entire content, but I have not seen the anime myself, so I can only use the information from the link.

Ok, thanks for the answer anyway. I found the description at volume 20 on Amazon, which describes what happened in the end quite well

Yes, I just noticed the mistake. Confused Starts at with Ends at. That's right, volume 20 should be. If you hadn't written that, I wouldn't have noticed it anymore.

Thanks for the star ^^
