Yan Luo was puzzled, but seeing Su Ruojin's serious expression, which didn't seem like she was joking, she repeated, "I said our medicine is effective."
"Wait, what happened to Hu Qing?"
"Hu Qing's tick bite hasn't healed yet..." Yan Luo was interrupted by Su Ruojin before she could finish speaking.
"I know what poison Deyi Kangren has been poisoned with!"
Yan Luo was stunned for a moment, then realized what was happening, her face filled with horror, "Miss, he wouldn't have been bitten by a tick, would he? What about Hu Qing..."
"Don't worry, Hu Qing will be fine. Deyi Kangren is different from Hu Qing. Let's go back to that secret passage again."
The secret passage had been cleared away. Because so many people had died, no one dared to approach it, which actually made it easier for Su Ruojin and her group to carry out their mission.
After descending the secret passage, Su Ruojin quickly found many ticks and collected them in a small jar.
Back at the villa, she instructed that no one should disturb her, and then locked herself in the pharmacy that had been prepared for her at the villa.
A day and a night later, Su Ruojin emerged.
Nian'er was waiting at the door with a plate of chestnut cakes. When she saw Su Ruojin come out, she quickly served it to her, saying, "Mother, are you hungry? Have some cakes."
Riko, who was standing nearby, quickly brought over a basin of water. "Your Highness, please wash your hands first."
Now, Li Zi also calls Xiao Yanchu "Prince" and Su Ruojin "Princess" along with Yan Luo and the others. She even changed into the clothes of the Great Chu and styled her hair in the Great Chu style, just like she was a person of the Great Chu.
Su Ruojin thanked Li Zi, washed her hands, took Nian'er's chestnut cake, and took a bite.
"Mother, is it delicious?" Nian'er asked nervously.
Su Ruojin smiled and said, "It's delicious."
Hearing her mother say it was delicious, Nian'er smiled, her eyes crinkling with pride, and announced, "Mother, this was made by Nian'er herself."
This surprised Su Ruojin. Xiao Yanchu, who had rushed over, smiled and said, "Nian'er feels sorry for you and said she wanted to make chestnut cake for you herself. She kept pestering Yanluo to teach her."
Su Ruojin was very touched. "Thank you, Nian'er."
Riko watched this scene from the side, a hint of emotion flashing in her eyes.
There was a time when she also experienced such happiness.
After eating chestnut cake, Su Ruojin and Xiao Yanchu went into the room.
"Ah Jin, is it done?"
Su Ruojin nodded, "I know how Deyi Kangren was poisoned. We started off on the wrong foot, always thinking it was caused by some kind of poison, but actually, half of the reason is that Deyi Kangren brought it upon himself."
Su Ruojin took out Su Ziyang's booklet containing records of Japanese herbs and poisons, and turned to one of the pages.
"Yanchu, look at this. In Japan, there is a poison called Soul-Losing Sand. It is called that because people who are poisoned by it will develop many red rashes. At first, the poisoned person will not feel any pain or itching, and no one will care."
However, over time, the rash can spread all over the body, even reaching the heart.
The Soul-Slaying Sand is colorless and odorless, making it difficult to diagnose before the onset of symptoms. According to Yamato records, there is no antidote; once poisoned, death is the only outcome.
Xiao Yanchu couldn't help but ask, "The symptoms of this Soul-Losing Sand poisoning don't seem quite the same as Deyi Kangren's symptoms."
One is black spots all over the body, which can merge into patches, causing pain and itching, and can also cause holes all over the body; the other is a red rash that is neither painful nor itchy. Obviously, the latter is much less toxic.
Su Ruojin nodded, "It doesn't seem like it, but..."
She took out a bottle from her bosom and poured some black powder into the teacup. "This is a poison I developed. It was made by adding Soul-Slaying Sand to ticks found in the secret passage of Saki Ken."
Ken Saki's secret passage is dark and damp, making it an ideal breeding ground for ticks.
The secret passage contained many corpses of people who had died from poisoning and some poisonous herbs. Ticks fed on these corpses and herbs, and over time, they also became poisoned.
