Bone Painting Coroner

Chapter 86 - The Answer

Liu Qingping was stunned for a moment, but recovered and stepped forward to greet Jing Rong, "This official pays his respect to Prince Rong. I don't know why Your Highness..."

Jing Rong raised his hand and interrupted Magistrate Liu, "You don't need to attend to me. Go and see what Teacher Ji needs."

"Yes, yes, yes..." The Magistrate went next to Ji Yunshu, "Ah! Yunshu, could it be that you found some evidence?"

"Lord Liu, right now, I need some vinegar and strong alcohol. I'll need to trouble you to bring them to me while I head to the autopsy room."

"Of course. No problem." Liu Qingping replied straightforwardly. He summoned two yamen runners and ordered them to find the materials Ji Yunshu needed.

While Ji Yunshu went to the autopsy room, Jing Rong sat in a room and drank tea. Ah~ Jinjiang's tea is really the best!

In the autopsy room, Ji Yunshu took out the rusted iron knife from her sleeve. Meanwhile, Wei Wu and Wang San came in with the vinegar and spirits.

"Teacher, what do you want to do with these things?"

"Blood test."

"Blood test?" Wei Wu and Wang San looked at each other, then they took out a notebook and a brush from their pockets, wetted the brush with their mouth and were ready to record what Ji Yunshu would say. Teacher's autopsy is a great source of learning! We must record everything, and maybe, in the future, we can become a coroner! That will be fantastic!

Ji Yunshu did not care about them as long as they could keep their mouths shut. She put on gloves and mixed the vinegar with the alcohol. After mixing for a moment, she dipped a white fabric into the solution and used it to wipe the knife. The rust gradually fell off with most sticking to the white fabric. Gradually, the black silvery glint of the knife was revealed.

Once the knife was cleaned, it was put into the solution. After a moment, dark red spots appeared on the edge of the knife.

"Eh? Why did it change colour?" Wang San exclaimed in surprise.

"This is not just any colour. It's blood."

"Ah?" Wei Wu and Wang San cried out at the same time.

Ji Yunshu held up the knife, and her expression was extremely tense. She had wished with all her heart that there would be no blood on the knife.

"How can blood appear like that?" asked Wei Wu.

"Because this knife was stained with human blood." Ji Yunshu stated to explain, "If you want to ascertain the presence of blood on a knife, or even on clothes, the best method would be a luminol test . However, using a solution which combines vinegar and alcohol would give a similar effect."

"What is that... lum..luminol test?" Wei Wu stammered on the word as he inquired.

Ugh! How should I explain it? She did not feel like explaining that part.

Instead, she put down the knife and uncovered the yin-yang skeleton. She picked up one of the broken hand bones. Then, she ordered the two yamen runners, "Like last time, go and bring me some camphor juice."

"Yes, sir." They went to fetch the camphor juice without asking further questions.T hey quickly and swiftly set up everything and just like last time, Ji Yunshu applied some camphor juice onto the skeleton's ankle. Next, she wrapped it in a white paper soaked in vinegar.

In less than a moment, the paper turned red. Soon after, she covered the knife with that paper. After the time it took for half a joss stick to burn, when she unfolded the paper, all the old blood on the knife has been imprinted onto the paper. The result turns out to be positive!
