Zeonic most certainly did NOT give up on their translation of this. Whoever was posting them here just stopped uploading. Maybe there's some agreement with Zeonic to not upload the most recently translated volume here or something. Regardless, you have to go to Zeonic Scans' website to download the next set of chapters. Volume 11 covers chapters 55-60.

If it looks like a group has stopped translating always go to the source to find out for yourself.
