Ainz walked inside the leftmost entrance, the moment he did he could see the passage was not just large, but it could fit several grown adult men, even if they walked side by side. At this point, he could see the green light he had once seen before, Ainz at first was about to turn back, but then he saw the green light, making him overjoyed.
'This must be the real one, it's the only entrance with the green light coming from it.'
He sped through the entrance, but found it empty that he couldn't feel the presence of even a single human face spider, this was different from them being scared by his presence, it was more like there was another powerful presence there.
'I know I killed too many spiders for me to even count them, but there should have still been some sign of them, I already killed all the rank 2 human face spiders, even if there were rank 3 am sure they were dead by now, except it's the spider queen!'
