'And then on one night we woke up, to hordes of magical beasts, we were doomed the moment the previous patriarch, my father, was swallowed in one gulp of the queen.'
"We were forced into this situation because the queen only wanted her children in its domain.'
When Ainz read this part, only one thought came to his mind:
'Snakes!'
He finally realized why he saw only snake-type magical beasts, it was because they were the children of the queen, which meant the queen was also a snake-type magical beast.
Ainz couldn't help but imagine a snake hundreds of meters long, he had seen such creatures in his previous world when he was a monarch, however, they could only cower in fear at his presence, he was sure that without distributing his free attributes points, he wouldn't be able to do anything against the Queen.
