"Imperial Uncle, if you need anything, you could just send someone to inform Qi Jin and Qi Yu, and I'll come to you," Zheng Congyuan was very polite, glancing at Prince Duan. His expression was calm. Although there was a hint of urgency, it didn't seem like he had come to accuse anyone.
Due to the haste of yesterday's events, by the time Qi Jin, Qi Yu, and the others had noticed the chaos at Prince Duan's Mansion, the Ghost Shadow had already entered, and amidst the panic, Zheng Congyuan had no choice but to come out "openly and honorably."
However, if one thought about it carefully, there were many flaws in yesterday's events. If Prince Duan thought it through carefully or entered the courtyard, he would have noticed numerous issues. By then, it would have been too late to remedy anything, only giving rise to more suspicions.
