Xie Yihui laughed heartily.

Cheng'en Hall.

Gu Yunru was observing the details of the scene with Cheng Shaoyuan, when she suddenly saw scattered fireworks blooming in the sky. She had never expected that there were fireworks in this dynasty. She didn't know how long it had been since she saw these colorful meteors streaking across the sky, and she instantly became yearning for them.

"Yunru, do you like watching fireworks?" Cheng Shaoyuan was beside her, his expression gentle and casual, but his tone was mixed with a hint of concern.

"Ah, well, I used to love watching fireworks and fireflies. Those bright, glowing things always fascinated me."

Gu Yunru looked up at the sky with a toothless smile, and Cheng Shaoyuan just looked at her in fascination. After a while, he caught a bunch of fireflies from somewhere and put them in a cage, and made a lantern with the fireflies.

"Where are the fireflies in this Cheng'en Hall?" Gu Yunru blinked at him confusedly and walked around the Cheng'en Hall. It felt majestic and solemn. In addition, two people had just died there, so there was a weird, strange and gloomy atmosphere here.

"It's in the main hall, and it seems to be Rongpin's backyard. There's a pile of weeds growing there." Cheng Shaoyuan handed the finished lantern to her. Gu Yunru smiled. She didn't expect her wish to come true.

"Thank you."

"No need to thank me." Cheng Shaoyuan felt relieved when he saw her happy. At this moment, he heard a woman's scream from the main hall. The two looked at each other and quickly ran to Rongpin's bedroom.

"Empress Rong?" Gu Yunru did not recognize this Concubine Rong. She had occasionally seen her in the garden. She had an elegant and cold temperament, and she did not like to argue about anything.

Concubine Rong was obviously frightened by something. Her face was pale and she was gasping for breath as she leaned on the edge of the bed. Her maid, Juxiang, was stroking her back.

"Empress...are you okay?" Ju Xiang looked at her worriedly. Gu Yunru glanced around the room and didn't find anything strange, so she asked Cheng Shaoyuan to stand at the door. After all, this was the Empress's boudoir.

"Who are you?" After being frightened, Concubine Rong finally reacted and saw Gu Yunru standing and walking towards her, looking at her warily.

"Don't be afraid, madam. I am here with the Dali Temple and the Ministry of Justice to investigate a case. Tonight is the Mid-Autumn Festival banquet. The nobles are eating, drinking and watching performances in the main hall, and the case here has not been resolved, so I came here to take a look."

Gu Yunru introduced herself enthusiastically, and Rongpin and Juxiang looked at each other.

"My lady, what frightened you? Are you having a nightmare?"

Rongpin and Xie Liangdi lived in the same bedroom. Could it be that Rongpin saw something that night but didn't dare to say it? Gu Yunru had this guess in her mind, but Cheng Shaoyuan said that Rongpin didn't like to fight for things, and there had been no quarrels or disagreements since Xie Liangdi moved in.

"Are you here to solve the case?" Ju Xiang looked at Gu Yunru in front of him expressionlessly. The woman looked familiar, but he couldn't recognize her.

"I guess so, Concubine Rong. You're not afraid anymore now, right?" Gu Yunru tried to persuade her patiently, but Concubine Rong seemed unwilling to say anything. After being frightened, she regained her composure and asked Juxiang beside her to leave first.

"Miss Gu, this matter is being investigated by the Dali Temple and the Ministry of Justice. There is no need for you, a woman, to investigate this case."

"What's wrong with women? Women can also investigate and solve cases." Gu Yunru said with her head held high. She was almost led away by this Rongpin. She sat down beside her bed, looked at her with a smile and asked, "Madam, did you find anything unusual that night?"

Rongpin carefully recalled what happened that night, but her memory suddenly became a little fuzzy, and she couldn't remember anything. She bit her lip with a pale face and said, "That night, I went to bed very early. I heard that it seemed that the emperor wanted to favor Xie Liangdi, but for some reason he went to the Yanxi Palace. I should ask your sister about this matter."

Gu Yunru looked at Rongpin's calm eyes and made a judgment in her heart.

"Yes, Concubine Rong is afraid of cats?"

"How do you know?"

"I heard a cat's cry when I came in. It must have run to the backyard by now. The backyard is overgrown with weeds and no one has cleaned it up. Could it be that the Queen buried something good there?" Gu Yunru asked jokingly, but unexpectedly her face turned paler.

"Haha, I was just joking with Your Majesty. Please don't take it seriously." After saying this, Gu Yunru stood up, smoothed her sleeves, and left her bedroom.

Cheng Shaoyuan, who was standing at the door, had been waiting for Gu Yunru. When he saw her finally come out, his eyes lit up.

"What happened?"

"It's okay, I was just scared by the cat outside. There must be something buried in the backyard. You can ask someone to check it out someday."

"kindness."

Juxiang had been watching the two people from a distance, and only breathed a sigh of relief when she saw them finally walk away.

Cheng Shaoyuan and Gu Yunru strolled under the pavilion and came to an empty dry well.

"Shaoyao, who was beside Xie Liangdi, entered the palace at the same time as her. Logically, the relationship between master and servant should be very deep. Why did Shaoyao kill Xie Liangdi?"

The clues at the crime scene were very confusing. According to what Cheng Shaoyuan said, someone must have tampered with the letter. As for the handwritten letter left by Concubine Shu, no one knew whether it was true or false. However, by comparing the handwriting, it should have been written by the same person. However, no one knew whether it was fake.

Cheng Shaoyuan looked at the waning moon tonight and silently lowered his eyelids. "Since I became the Junior Minister of the Dali Temple, this is the first time I have encountered such a complicated case. Although Xie Liangdi died at the hands of Shaoyao, Shaoyao doesn't know kung fu. Could it be that she was controlled by someone?"

Gu Yunru looked at his wild imagination and actually thought of being controlled by someone. She couldn't help but sneered and said, "How can you control him? Could it be using the Miaojiang Gu worm? Don't tease me, that thing doesn't exist at all."

As an atheist, although Gu Yunru is good at using psychology to understand other people's intentions and motives, she still can't believe in such things as controlling people's willpower.

"Have you ever heard of the Guwu tribe?" Cheng Shaoyuan stared at her seriously and said, the name really sounded familiar.

"I've heard of them. Aren't they selling tea?" This was the only impression Gu Yunru had of them.

"Legend has it that the tea sold by the Guwu clan can control people's minds."

Seeing that he believed it, Gu Yunru mocked him mercilessly. "I don't believe it. Unless one day I am controlled, I won't believe it."

After that, the two of them continued to enter the scene where Xie Liangdi was murdered. The bathtub was still there, and everyone present had completed the survey, but still no new discoveries were made.
