One night, an uninvited guest made their way to Su Bin's residence, concealing their identity behind a mask. Su Bin had forewarned two trusted guards not to interfere with the unexpected visitor.
Prior to this nocturnal encounter, Su Bin had received a cryptic letter from someone who had hinted at an impending visit, identifying themselves as an uninvited guest. This mysterious individual possessed extraordinary martial skills, capable of vanishing without a trace.
Before disappearing once more, this enigmatic guest left behind a pair of gleaming gold bars along with a note. The note expressed gratitude towards Su Ning, without specifying the identity of the youth whose life she had saved. It hinted that, had Su Ning not acted promptly, the young man might have perished from his injuries.
