"...Naela, right?"
Upon hearing this, Fylson nudges Naela's arm with his elbow signaling that Rex is talking to her.
Realizing this Naela stutters for a fair moment and nervously looks at Rex and puts on a polite smile, and this makes Rex realize something. 'It seems she can only speak Dark Elf language, that's going to be a problem'
"Let me ask you one thing, how did you meet with Kyran?" Rex asked.
Instead of using his own language, he decided to use the Dark Elf's language. Learning languages from the system doesn't only allow him to read, but he can also speak the said language. Even right now he can also speak the Orc language if he wanted to.
For some reason, the high-rank Supernatural races used human language instead of their own.
