The case of Leng Jingxian poisoning and attempting to harm her was already thoroughly interrogated by Prince Ning in court. Although Leng Jingxian fainted in court and Prince Ning postponed the judgment, Su Yunjin estimated that within the next two days, Prince Ning would certainly call them back to court to pass a sentence. After all, it was unlikely that Prince Ning would keep delaying the verdict on Leng Jingxian's crime for an already concluded case.
Gu Ya mentioned that Prince Ning wouldn't stay here for long and might leave as soon as next month. Prince Ning still had other matters to attend to, and the issue with Leng Jingxian was only addressed due to Gu Ya's request. Prince Ning helped out of consideration for the friendship with Prince Rui and his wife, and Gu Ya himself. By resolving this matter sooner, Prince Ning wouldn't have to spend more effort and thought on it.
