At the moment they saw Jiang Chengxuan, the members of the Sacred Skeleton Sect's faces drastically changed. Jiang Chengxuan's identity and appearance were notoriously well-known within the sect; he was essentially their arch-enemy.
Among them were higher ups of the sect who had personally witnessed Jiang Chengxuan fighting their sect master on the day the Haoran Sect attacked. The battle was intense and evenly matched.
Although they had cultivators of Dao Mastery among them, they knew they were still not a match for Jiang Chengxuan, the Master of the Haoran Sect.
However, just as they began to panic and thought about fleeing, the sharp-eyed leader of the demonic cultivators noticed something unusual about Jiang Chengxuan. He saw Jiang Chengxuan's surprise upon recognizing them but also noted that Jiang Chengxuan had not attacked them yet. This led him to suspect there was more to the situation than met the eye.
