Although both Xiao Yan and Tang Qiying had increased their strength, Xiao Yan's situation had become even more dangerous than before. After all, Tang Qiying was using the Flame Clan's clan mark.
An invisible pressure swept out with a roar, suppressing even Xiao Yan's enhanced aura by a level.
During this time, Xiao Yan had systematically learned about clan marks from Huo Zhi and Lei Jingxiao. To descendants of Dou Di, clan marks were the most profound secret art and the one best suited to them. Not only could clan marks temporarily increase one's strength like secret arts, they also lacked the severe backlash and aftereffects of secret arts, eliminating the need to endure a weakened period after using them. Moreover, only descendants of Dou Di with ancient inheritances could cultivate this ability; others had no way of touching it.
Now that Tang Qiying had taken possession of Huo Xuan's body, he was also taking the opportunity to activate Huo Xuan's clan mark.
The gap between the Three Mysterious Changes of Heavenly Fire and a clan mark had already become apparent. Tang Qiying had now officially advanced to the middle stage of the one-star Dou Sheng realm, while Xiao Yan could not use a secret art to break through the boundary between Half-Saint and Dou Sheng. The difference between them might not have seemed great, but the gap in actual strength was enough to drive ordinary people to despair.
