Su Rong successfully left the Eastern Palace and climbed over the city wall. As she landed, she was about to step away when she suddenly felt something amiss. Glancing towards the shadowy corner of the wall, she found someone standing, a man she knew all too well.
She stopped dead in her tracks.
Zhou Gu was standing in the shadowy corner of the wall. He had purposefully come to wait outside the Eastern Palace wall that night. Upon spotting a familiar figure stealthily slipping into the palace in a nocturnal robe, he didn't startle her but waited here. After an hour, she came out just as stealthily.
He confirmed that Su Rong had arrived in the city much earlier. Before she encountered Duanhua, her traces were being erased by the Crown Prince himself.
And she had long been in contact with the Crown Prince.
The realization further cemented his suspicion that the Crown Prince already knew of Su Rong's identity.
