If this had happened before, Gao Jinmei would have been furious if someone leaked her appearance, and she might have killed everyone who knew about how she looked. But now, Gao Jinmei no longer had an interest in continuing down the path of an assassin; whether her appearance was revealed was no longer too important to her. Moreover, her tasks as an assassin were always carried out discreetly—nobody knew who she killed in any given assignment, and thus there was no need to worry about revenge seekers knowing her face and coming after her.
After hearing Gao Jinmei's explanation, Qi Tian was similarly unconcerned. He had not felt any malice or killing intent from the cultivator who had hired them, and if Qi Tian had sensed any of these through the Heavenly Dao Engine's detection of Spirit Qi, he wouldn't be so calm now.
