Ainz raised his head after reading the book and looked at Bruce, according to the old book Orochimaru was a snake-like beast, that was said to have been half man and half snake, it was said that it sometimes resembled a beast and sometimes a man, nevertheless, its most notable legend was the fact it could pull out a long sword or spear from its mouth and cut to death it's victim in its snake form.
When Ainz saw that part of it, he was a little surprised he couldn't help but wonder if the Orochimaru was similar to how he possessed a wyvern bloodline, although he had seen beast men that could take on human form back in his former world, he wondered if it was really the case.
