How could Su Bin remain oblivious to the emperor's thoughts?
It was precisely the emperor's suspicions that rendered Su Bin uncertain about standing by his side. In normal circumstances, being close to the emperor would have been the most effective and expedient means to undermine the Crown Prince's authority.
However, the emperor's doubts were a formidable obstacle. If the emperor believed that Su Bin had connections with the Public House, a mere verbal decree could seal his fate. Su Bin couldn't afford to take such a perilous risk.
There was simply no need to gamble recklessly. His alliance with the Third Prince remained tenuous, and the Third Prince lacked the strength to contest the Crown Prince's dominance. Furthermore, the General Manor was a perpetual source of discord and disturbance.
When all these factors were considered, Su Bin and Qin Zhenzhen decided that a more cautious approach was warranted in their efforts to undermine the Crown Prince.
