Because Lóng Wei got injured, the investigation regarding the attack behind Xiaoming stopped briefly. However, after Shui Xiaoqing died mysteriously, and the matter ended with that, General Hei Chengxi began the investigation again.
Yi Xinze did what Lóng Wei had told him to do. He told Hei Chengxi that someone from the palace had ordered him to harm the Crown Prince. He told Hei Chengxi everything that he had told Lóng Wei.
"Father, do you believe his words? For many years no one tried to harm the Crown Prince," Huang Xi said as he stopped his father from going to the King.
"Huang Xi, enemies become as you grow in power," Hei Chengxi told his son. "Crown Prince Xiaoming is the next-in-line king, so maybe consorts or concubines are behind this attack. We cannot jump to conclusions yet as to who was behind it and only ask His Majesty's permission to investigate everyone in the palace," he added.
