Since they could not find the cause of the poison, Zhuo Hui still died three days later. The emperor, the empress dowager and the empress dowager were not present, and such a thing had happened in the palace, causing everyone to panic. They did not know what to do, and the Imperial Concubine Zhao even came to Rong'er to discuss urgently. The funeral of the princess was handled by the internal affairs office. The news of the princess' death was immediately sent to Shengjing, awaiting the return of the emperor's decree. A few days later, news came back from Shengjing saying that the emperor, empress dowager and empress dowager had heard of the princess' death and were grieving over her death. The emperor had buried her in the palace with the ceremony of a princess, and at the same time, the imperial court was investigating the matter closely, so that when the empress dowager and empress dowager returned to the palace, they would find out who did it.

Zhuo Hui was dead, and Zhang Leyan sat there motionlessly all day long, not like Rong'er and the noble lord had lost their princes to tears. She didn't speak, nor did she move, just sat there blankly, and Rong'er knew that the times the Emperor called her over was very few, and now that Zhuo Hui was dead, she didn't cry, but instead held in her emotions. This way, her body would become even more injured, and if there was pain, she would be released.

In the end, Rong'er really couldn't think of a cure for the poison. With Zhuo Hui, Zhang Leyao had kept a very low profile throughout the past two years, rarely leaving the Palace. No matter how much the poison was administered to Zhuo Hui, it shouldn't have been administered to him.

One noon in early November, the emperor, empress dowager, empress dowager, and empress returned to the imperial palace. Once the empress dowager entered the palace, she ignored her exhaustion and summoned everyone together. At the same time, he also called for the Head Supervisor of the Internal Affairs Bureau and a teacher of the Shang Fang Courtyard. GaoRong'er didn't see the emperor. He heard that the emperor had come back to meet with the court officials at the Palace.

"The Emperor and This Dowager have only been gone for two months. How could such a big thing happen in this palace? How could Zhuo Hui's obedient great-granddaughter disappear just like that?" The empress dowager frowned as she asked.

Upon hearing the empress dowager's question, Zhang Leyao silently lowered her head to look at the ground.

"Who among you will tell this story to This Dowager in detail?" The Empress Dowager continued to ask as she stared at the crowd.

In the past few days, she had been in a state of panic quite a bit. Thinking about how this had happened in the Peace Palace, she should have been the one to explain it to her, thus she said, "Old Ancestor, I, Rong'er, will tell you more about this matter …" Seeing the empress dowager nod her head, Rong'er recounted everything that happened to Zhuo Hui before, how he suddenly became ill, how the imperial physician examined him and said that he had been poisoned, but was unable to find any poison.

"Poisoned, hmph, there is someone in this palace who dares to poison us!" "Cui Caide, tell me what's going on." The empress dowager spoke harshly to Cui Caide, one of the teachers from the Shang Fang Courtyard.

"Yes …" Cui Caide's forehead was dripping with sweat. He hurried forward and said, "Reporting to the empress dowager, the servants who poisoned her have already investigated."

"Oh? Did you check it out? "Who is it?" the empress dowager asked angrily.

"According to the servants' investigation, it's Zhang Gouzi, who's working in the imperial kitchens." Cui Caide replied.

"Doing chores? A mere servant dares to be so bold? " The empress dowager frowned. "Who ordered him to do this? Why did he poison the princess?"

"Reporting to the empress dowager, during these few days, this humble subject had investigated the matter, and found out that on the same day, Young Master Zhang had ordered the kitchen to cook soy milk, and on the same day, Ah Sheng, the imperial chef, ordered Zhang Gouzi to grind beans. As Zhang Gouzi did not do well in the past, Ah Sheng had scolded him, and he was filled with jealousy and secretly poisoned in the ground beans. Cui Caide reported.

"Then what should we do with this Zhang Gouzi now?" The Empress Dowager continued to ask.

To the empress dowager, this subject and others would have locked him up and waited for the emperor to return and personally bring him up for questioning. But he was afraid to see His Majesty. Cui Caide wiped the sweat from her forehead and handed the confession in her hand to the empress dowager.

The empress dowager took the evidence and looked at it before asking, "Did you really ask for the details?"

In the past, everyone had only thought that he was stupid, but they had not expected that he would do such a thing. After many investigations, the Shang Fang Academy combined with his usual personality, and treated it as correct. Cui Caide reported.
