Song Jian noticed that the Abyss Temptations and the Fallen Angels here seemed to be more spirited than the ones outside. Some of them even engaged in quiet conversations. They all spoke in the language of the Abyss which wasn't a problem for Song Jian.
A Fallen Angel brushed past Song Jian, causing him to tense up. This Fallen Angel appeared to have sensed something and turned to look in Song Jian's direction, its eyes filled with confusion.
Song Jian stood perfectly still. A bead of cold sweat rolled down from his forehead, down his cheek. After a moment, the Fallen Angel shook its head and continued to walk forward. Song Jian managed to catch the drop of sweat, his heart pounding.
It seemed that the Abyss Concealment Skill inherent to the Concealment Necklace was of a high level, able to conceal him even from the perception of a level 40 Elite Boss.
