Human language!
The words spoken by the tall leader were actually the universal language of humans.
Although he was very unnatural, like a foreigner speaking another country's language, it was indeed human language.
Surprised, Su Jingxing replied with a question, "You are the Winged Ones?"
"You know that we are the Winged Ones?" The tall leader was delighted, but he thought of something and quickly restrained himself. He asked again, "Are you a human spiritual martial artist?"
"So what if I am and so what if I'm not?" Su Jingxing replied coolly.
"You are definitely a human spiritual martial artist!"
