Sir Duren was sent to Red Rock Island without knowing when he would return, so Li Yu had agreed to leave Lion Heart Castle tomorrow, surely unable to wait that long.
Thus, the original plan was no longer viable, and they had to take a slight risk, but only if Duren agreed to be rescued.
Making such a choice was not easy for Duren, as it meant he could no longer retain his title or reputation.
For many nobles, this was worse than death, not to mention it might also implicate his family.
Duren pondered for a long while until he remembered Li Yu's previous words: if he just went to Red Rock Island, no one would seriously investigate the real murderer of Edward II afterward.
Based on Duren's understanding of Gars and the nobles of the Royal Capital, they would likely find a scapegoat to take the blame for everything.
That way, the matter would be considered satisfactorily resolved.
