On that day, Tang Jian personally witnessed Su Chengyu employing the "True Way of Controlling Thunder" and the "Supreme Cave-void Sword" in Mist City, and after he left through the Teleportation Circle, Tang Jian decided to thoroughly investigate the matter, but not knowing where Su Chengyu had teleported to, he had no choice but to wait in Mist City for his fellow disciples to arrive and report the incident.
When Su Chengyu teleported to Mist City, it so happened that his senior brother Lu Jingzong had arrived before him and met with Tang Jian, discussing this very matter.
Initially, Lu Jingzong did not believe that a disciple from outside the Quanzhen Sect could have mastered their sect's top techniques.
While the two senior brothers were discussing the matter, Su Chengyu emerged from the Teleportation Circle. Tang Jian recognized him at a glance, and the two immediately clashed.
