Lord Ni was an official from the Imperial Censorate who came forward to impeach Wen Yuesheng during the morning court session. His reason was that her execution of Sun Mingyuan had been too swift and decisive, and she had executed him without informing the emperor. He argued that when officials commit crimes, there must be a thorough investigation, and once the evidence is conclusive, it is up to the emperor to decide. He claimed that the princess's action of executing Sun Mingyuan without reporting to the emperor violated proper procedure and raised suspicions of silencing him. However, Lord Ni was not from Prince Heng Guang's faction, and his impeachment was driven by his genuine belief that Wen Yuesheng's actions were inappropriate rather than by political motives. When Wen Yuesheng revealed that she knew the mastermind and presented evidence, Lord Ni was left speechless and unable to continue his impeachment.
