He didn't know if it was a curse, but whatever it was, it wasn't good.
The dark cyan rune mark flashed and disappeared, Yang Zhen, regardless of his search, could not find it. Even with the power of his spiritual sense, he had thoroughly examined every part of his body, even doubly checking his private parts, but found nothing.
It was so strange!
Not only could he not find anything, but he didn't even feel anything peculiar, as if the thing, which seemed like a curse, had been as fleeting as an epiphyllum flower, and then had completely disappeared.
Since there were no anomalies, Yang Zhen didn't worry too much.
Not to mention that Yang Zhen was sure that there were other demons here, this type of nearly childish curse shouldn't have been able to kill him, so there was no need for him to worry too much.
As long as he wasn't going to die, he could just ask another demon about what this thing was.
This really wasn't a big deal!
