At the end of the first analysis of the evidence, the most suspicious on the field were the eldest princess and the imperial doctor, after all, from the perspective of motives, these two people are most likely to want to kill the queen mother, and only the imperial doctor has this kind of unaware ability to drugged.

In the second evidence collection, the program team randomly divided into groups in pairs, and it was not the same as the first time the evidence was collected, Qiao Anan was very unfortunate and was assigned to a group with Gu Ting.

"When we were collecting evidence, the camera was shooting all the time, you have to ...... Be cautious in what you say and do. Before the formal search, Qiao Anan reminded Gu Ting euphemistically.

"I understand."

"There were no obvious blunt force wounds on the Queen Mother's body, but she died suddenly of poison. Therefore, there is no need to dwell on the timeline, because the poison takes time, we just need to focus on what the Queen Mother smells or eats and drinks, where there may be poison. ”

Jo An'an's search was quickly proven correct.

This time they searched the mansion of the Household Department Shangshu outside the Forbidden City, and the lady of the Household Department Shangshu had taken in an orphan girl named Ah Bao in the past few days, and the orphan girl was found with the entrance number of the palace on her body, and bought a lot of five-stone powder in the pharmacy in the west of the city.

"Five stone powder? Sounds like poison, it looks like a clue is coming! Qiao An'an decided to go to the pharmacy in the west of the city to investigate, and the shopkeeper of the pharmacy, as an NPC actor invited by the crew, acted very into the play, and saw the two of them in expensive clothes coming to the store, first flattered and stammered, and when they said that the purpose of the trip was to investigate the homicide, they changed their look of cringe.

"My lord, my lord has wronged! These five stone powders are not poison! ”

The shopkeeper Lao Li Tou explained, "The summer is hot, the heat is unbearable, and the five-stone powder is a holy product to cool off, and many officials and ladies will buy it!" Don't wronged the villain, my lord! ”

"Five stone powder is a holy product to cool off? Then you can teach me how to beat the heat of this five-stone powder! Jo Ann asked.

"Just have some five-stone powder under your tongue, and it's easy to use. However, there are also taboos in the use of five-stone powder - "The shopkeeper hesitated, but he didn't say everything."

Qiao An'an was in a hurry, and her intuition told her that this was the key to solving the mystery of the script.

"For an hour after using five stone powder, you can't take too much ice water! Otherwise, it will damage the body! ”

"It's just an injury, isn't it fatal?" Gu Ting pondered, assuming that the medicine that killed the Queen Mother was Wushi powder, but the amount contained under the tongue would not kill a person.

The shopkeeper shook his head, "It's not enough to die, but under the injury, if you are stimulated by something and you are in a hurry, then you are likely to die!" ”

The fragmented clues were suddenly pieced together in an instant, and Qiao Anan slapped her palms and had the answer!

"The ingredients that can be detected in the incense burner are only the sleeping spices prescribed by Imperial Physician Shen to the Queen Mother, which is not what killed the Queen Mother, the Queen Mother died because of these five stone powders, do you remember the white fungus soup sent by the Queen? The weather is so hot, the white fungus soup sent must be cold, that is, the white fungus soup aggravates the effect of the five stone powder, and the body of the queen mother is damaged. ”

Knowing the truth, Qiao An'an smiled, this was the first time Qiao An'an smiled so happily after Gu Ting and Qiao An'an reunited, Gu Ting looked at her gently beside Qiao An'an, her eyebrows and eyes seemed to be soaked in honey, and she was full of doting looks.
