Chapter 526: All clues point to one person

Yu Lingye sighed.

He had to praise the meticulousness of this method of committing the crime.

The murderer first released the poisonous insects into the sewage in the palace at a specific time, and the poisonous insects were discharged into the Yujing River through the sewage channel.

Then, they took advantage of the time difference during the rainy season in Shangjing when the Huozhao River would raise its embankment in a short period of time, and transported the poisonous insects to various open and underground ditches in Shangjing through the Yujing River, allowing the poisonous insects to reproduce in various sewage ditches.

When the time comes, the poisonous insects will burst out and turn into poisonous mist.

After the poisonous fog spread, the murderer used the customs of the Ghost Festival to justify the poisonous fog.

Step by step, carefully planned, each link connected to the next.

If I hadn't met Xie Yingmian,

If Xie Yingmian hadn't discovered that there was a hallucinogenic poison in the thick fog,

If they hadn't investigated water samples from various places,

I'm afraid no one would have thought that the fog of hell and the night parade of ten thousand ghosts were all created by the murderer!

This case is even more surprising than the three strange cases of Dayu recorded in the Dali Temple.

Xie Yingmian seemed to be thinking: "Now that you mention it, I think of a kind of poisonous insect."

"What a coincidence! The insect's name is Mayfly Gu."

Yu Lingye: “Oh?”

Xie Yingmian: "Mayfly Gu is a very special kind of Gu."

"From the outside, it looks like a translucent insect the size of a grain of rice."

"The surface of the mayfly insect is covered with dense scales. It likes water, hot, dark and humid environments. Its breeding season is in the sixth month of the lunar calendar."

"Unfortunately, I only remember a brief introduction to the Mayfly Gu, and I don't know the details."

Yu Lingye didn't ask any further questions.

They have determined the murderer's location and mastered the method by which the murderer released the poisonous fog. That is enough.

Furthermore.

The murderer uses the mayfly poison to create thick fog only once a year, which is the Ghost Festival.

The Ghost Festival has passed and the murderer has no chance to commit the crime again.

They still have a year to investigate, so there's no need to rush.

Xie Yingmian said, "According to the clues we have so far, the murderer is in the palace. He is skilled in using poisonous insects, and he is of high status."

"All these clues point to one person."

Yu Lingye: "Aunt Yu."

Xie Yingmian: "Yes."

"On the surface, Aunt Yu seems to be following the Queen Mother's orders, but the Queen Mother's identity is questionable, and the actual situation remains to be investigated."

Yu Lingye tapped the table intermittently, "The Queen Mother has a special status and has lived in the inner palace for many years, so it's difficult to investigate."

Xie Yingmian nodded: "Indeed."

"However, the news of my treatment of the victims of the poisonous fog must have reached Aunt Yu or the Queen Mother. They may find an opportunity to test me."

"Are there any special occasions recently? For example, a flower viewing party, a lotus banquet, a summer cooling banquet, etc."

Yu Lingye lowered his narrow eyes slightly: "Mid-Autumn Festival is coming."

"During the Mid-Autumn Festival, there is a Mid-Autumn banquet in the palace."

Xie Yingmian: "The Mid-Autumn Festival Banquet is indeed a good opportunity, but I don't know how they will test me."

She was a little excited.

The Empress Dowager has a special status, and the palace she lives in is even more special.

Unless there were special circumstances, she had almost no contact with the Queen Mother.

Even if he had the chance to meet the Queen Mother, he would not be able to meet Aunt Yu who was beside the Queen Mother.

When she hypnotized the emperor, she could see from his subconscious attitude that he respected Madam Yu.

Aunt Yu has many secrets hidden in her body.

She really wanted to know why the poisonous insects used by the Gu Clan behind Aunt Yu were exactly the same as the poisonous insects in her memory.

The Du'e Gu, the Pea Gu, the Mayfly Gu, and the Gu that had infected Duke Ningguo, Lu Sheng, and others were all the same as the Gu in her memory.

What is the relationship between Aunt Yu, the Gu tribe, and the 29th century?

What is their relationship with Shen Yu or Xie Jingyun?

She had a hunch that she could get useful information from Aunt Yu.

Yu Lingye mentioned several possible ways to test Xie Yingmian. Seeing that Xie Yingmian didn't respond, he tapped her forehead with his finger: "What are you thinking about?"

Xie Yingmian chuckled: "I feel like we can both change our careers."

"We worked together to solve such a bizarre case in just two days. It shows that we both have some talent for deduction."

Yu Lingye bowed and said, "Indeed, the princess's talent for reasoning is far beyond my reach."

"Chen Tingsi and Ji Yunzhang have to admit defeat."

Xie Yingmian's eyes curved. "I'm not that arrogant, I still know myself. This time it was just luck, and it just happened to be my specialty."

Yu Lingye got down to business: "There are some things you need to know in advance about the Mid-Autumn Festival banquet."

"At the Mid-Autumn Festival banquet, male and female relatives still sit separately, but this time the division is different from the previous ones."

"During the previous sittings, although the men and women were separated, the distance between them was not far."

"It might be just across a bridge or across a courtyard. If anything happens to the women, I can go over and provide support at any time."

"The Mid-Autumn Festival banquet is different."

"The male relatives are in the Jiuxiao Palace in the front hall, and the female relatives are in the Fengyi Palace in the harem."

"The Jiuxiao Palace and Fengyi Palace are quite far apart. If something happens to you, I won't be able to provide timely support. Moreover, the palace is a key area, so only two maids can be brought in, and the secret guards cannot enter. This is very disadvantageous for us."
