Shi Lei was mistaken for an evil cultivator by Yi Xiaobai and Qian Duoduo.
Qian Duoduo even engaged Shi Lei directly in combat, intending to capture him and drag him back to the Seal-Suppressing Pavilion. Throughout the fight, Shi Lei merely used a Dark Iron Saber to tangle with Qian Duoduo, while Qian Duoduo wielded a coin sword. The two traded blows back and forth right at the city gates of Yishui City.
Since Qian Duoduo wanted to take Shi Lei in to face justice, he was holding back and not going all out. Similarly, Shi Lei had no desire to kill him; wanting to avoid offending these two investigators from the Seal-Suppressing Pavilion, he simply used the Dark Iron Saber to spar with him.
