Su Ruojin glanced at it and then looked at Yan Luo, "What do you think?"
“I also suspected it was the Bewitching Powder, just like you, but there was no reaction after adding vinegar, so I realized I was looking in the wrong direction. Then you said to add alum, and I realized that this should be the Soul-Dazzling Pill, which has a more pronounced effect,” Yanluo said, explaining her analysis.
Su Ruojin nodded approvingly, "That's right, it is the Soul-Dazzling Pill. The Soul-Dazzling Pill contains an ingredient called Gallnut, which releases a blue color when it comes into contact with alum."
Strictly speaking, gallnuts are not actually poisonous, but they are an essential ingredient in making the Soul-Sealing Pill. Gallnuts contain a large amount of tannins, which will undergo a complexation reaction when they come into contact with alum, turning the color blue.
However, the technology of this era had not yet reached the point of being able to analyze components, so Su Ruojin would not reveal these details; as long as Yan Luo knew the reason, that was enough.
The Soul-Dazzling Pill doesn't initially cause much reaction in the person who takes it, nor does it kill them.
However, as the medication accumulates, the brain gradually becomes numb, and dizziness may occur at any time. Losing control of the hands and feet can easily lead to falls.
This is why all members of the Xu family died from falls in different places.
It appears to be an accident, but in reality, someone is poisoning the Xu family behind the scenes!
Yan Luo raised the bowl in her hand. "Everyone, the Xu family did not die in an accident. They were poisoned with a drug called 'Dizziness Pill,' which caused them to be constantly dizzy and unable to control their hands and feet, leading to their falls and deaths. This drug turns blue when it comes into contact with vinegar and alum, and this bowl proves everything."
If you don't believe me, I suggest the coroner examine any other deceased member of the Xu family using the same method.
When Yanluo said this, everyone looked incredulous.
Who would believe that so many members of the Xu family were poisoned?! Who in Yulin would be so audacious?!
Upon hearing Yan Luo's words, Judge Huang's heart skipped a beat.
He never expected that what he had done so secretly would be discovered.
Just who is this Zhao Ruojin?!
Putting everything else aside, this Soul-Dazzling Pill is not some poison that can be bought casually. My master spent a thousand taels of gold to buy it back then.
Most doctors had never heard of the effects of this poison, and some couldn't even detect it by taking a pulse.
They tested it out before daring to use it on the Xu family.
I never expected that Zhao Ruojin, that little maid, could find out the truth just by examining a corpse!
What Judge Huang was unaware of was that the Heavenly Medicine Pavilion would collect all the poisons in the world and conduct research on them.
The Soul-Dazzling Pill is one of them. This poison is not from the Great Chu, but was introduced from the Northern Li. When Su Ruojin heard about the symptoms of the Xu family, she already suspected that someone had poisoned the Xu family.
Initially, she suspected it was ordinary Bewitching Powder, which had similar effects to Soul-Dazzling Pill. However, the ingredients used in Bewitching Powder were too potent and took effect very quickly, making it easy for people to detect.
The drug "Bewitching Powder" turns red when it comes into contact with vinegar, but Yan Luo tested it just now and there was no reaction. Su Ruojin immediately guessed that it was not "Bewitching Powder".
Only then did they add alum to Yanluo to test it, and sure enough, it worked.
But thinking about it, it makes sense. If you're going to harm so many people, you can't do it without spending a lot of money.
Huang Tongpan felt a chill run down his spine.
The old coroner had been examining corpses in the government office for many years and had never heard of such a thing. Driven by curiosity, he went to examine the bodies of several other deceased members of the Xu family before Judge Huang gave the order.
Sure enough, every single one of them showed the same reaction.
To make a comparison, the old coroner even dripped a drop of his own blood into the bowl, but nothing changed.
If some people had previously suspected that Yan Luo had done something wrong, now that the old coroner had done it himself and prepared the materials in advance, it was impossible for him to have done anything wrong.
The crowd stirred, and the constables quickly stepped in front of them to prevent any accidents from happening.
