Xu Fan carried out this secret operation unnoticed by anyone present, so confident was he in his superb skills that he believed even Martial Kings or perhaps Heavenly Venerables couldn't detect any clues.
Xu Qiyin, who received Xu Fan's pardon, showed a joyful expression of someone who had survived a disaster, and from the bottom of his heart believed he had wronged Xu Fan. He was very grateful that the other party had shown restraint, not taking his life, and even spared him from suffering too much pain, merely giving him a verbal warning.
He was thus able to preserve his most basic dignity.
Of course, a person's gratitude can fade over time, even vanish. When he returned to his family and once again lived the comfortable life, secured in his personal safety, enjoying the superior treatment of a Young Master, things would go back to how they should be.
An old saying goes: "The landscape changes, but human nature stays the same."
Indeed, there is reason in this!
