To a natural poisoner, what was the easiest and fastest way to know what poison was?

Very simple, it was directly savored!

But because the shopkeeper had emphasized repeatedly before the third round of the competition, and he was not allowed to try, Liu Xinyue could only secretly try it out while he was in the medicine box.

However, before she had tasted the poison, Liu Xinyue had actually already thought of an answer in her heart. It was only to make her more certain that it was the answer she was thinking of.

And after she had tasted it, Liu Xinyue realised that the answer he had gotten from observing her was correct.

Thinking of this, Liu Xinyue instantly had the corresponding detoxification method. After that, she pretended to take a few of the simplest tools and fiddled with them, at the very least showing them off for everyone to see.

Otherwise, if she said out all the answers at that time, and was even right, and no one saw how she observed and distinguished them, they might even suspect that she had cheated, or that she had colluded with wan chun tang in advance, or something like that.

One had to know that it was hard to predict the hearts of men, let alone in the country where the power of the royal family reigned supreme. It was even more impossible to have pure intentions. Otherwise … If that happened, how would they offend people? How would they even know how they died?

Liu Xinyue took the small bowl and imitated the closed disciple of the Southwest Poison King. He scooped up the black poison powder and placed it inside the small bowl, then poured some water into the bowl and sprinkled some of the poison powder inside his own medicine box.

After doing all this, she started to stir the black poison powder with a spoon. After a few rounds, Liu Xinyue could see the red particles within the black poison powder floating above the water surface. Everything just now perfectly separated the black poison powder from the red particles, allowing people to see everything at a glance.

After seeing this scene, Liu Xinyue gave the small bowl to Ya Er, and then took out a pen and paper, and quickly placed the paper on the square table, and started to grind it.

Just as Liu Xinyue was grinding, He Ming also stopped observing, and at the same time took out a pen and paper, looking as though he already had the answer from his observation, he started to prepare the detoxification method.

"Seeing you like this, Dr. Huo probably already has an answer in his heart, right?"

He Ming did not need him to grind the ink, instead, it was Chong De who helped him grind it. Taking advantage of this gap in the grinding, He Ming looked towards Liu Xinyue and asked with a smile.

"Haha, isn't Doctor He the same?" Hearing that, Liu Xinyue saw that the grinding was complete, so he put down the ink, extended his hand to pick up the brush, and laughed: "Doctor He is truly amazing, in such a short period of time you have completed the research, I am impressed."

"Hehe, Dr. Huo is so funny, don't tell me that Dr. Huo is even faster than me?" Hearing that, He Ming laughed as he looked at Liu Xinyue, then looked at the small bowl in Ya Er's hands, and shook his head.

"Actually, my apprentice alchemist and I were researching it together. Their combined speed was so fast." After Liu Xinyue heard this, he immediately shook his head and denied it, and said, "It's not like Doctor He is able to do it so quickly by himself, if I were to do it myself, I wouldn't be able to do it."

"Hehe, Dr. Huo is being too modest."

Hearing Liu Xinyue's explanation just now, and seeing that Liu Xinyue also told his own medicine boy to go and observe the poison, He Ming believed what he had just said.

Although he said this to Liu Xinyue, his expression was no longer as fake as before, and there was a slight raise of the corners of his mouth. Obviously, after hearing this, he could not help but become complacent.

"Then, this one shall not disturb Doctor He's business."

Seeing that, Liu Xinyue pointed to the ink that Chong De had grinded already, and said to He Ming.

"Alright, then I won't disturb you."

Seeing that, He Ming nodded his head, he picked up his brush and dipped it in ink, then started to write the antidote.

Seeing that, Liu Xinyue retracted his gaze, used his brush to get some ink, and then quickly started to write on the paper.

Since the antidote for poison was already in Liu Xinyue's mind, he didn't need to think about it anymore. After writing it all down in a few moments, just like the others, he folded the recipe and wrote his name on it. Then, he placed it on the tray of the first poison.

After the first poison was observed and wrote down, Liu Xinyue intentionally glanced at He Ming who was standing opposite him. Seeing that he was still writing, Liu Xinyue didn't bother to pay attention to him and instead made Ya Er put the small bowl in his medical case before walking towards the second veiled lady.

After He Ming finished writing the prescription for the detoxification, she realized that Liu Xinyue had been observing the second poison for a long time already.

"Go, fold the prescription and place it on the tray."

Seeing this, He Ming pursed his lips, retracted his gaze, and gave Chong De the antidote he wrote, allowing him to place it on the tray. Then, he slowly walked towards the second veiled lady.

Liu Xinyue was currently observing the poison in the second tray. From the color, it looked green, and from its shape, it was no longer a powder but a paste. At the same time, bubbles kept popping out from the green paste, making it look extremely disgusting.

It was as if … It was like a boiling swamp.

"That color must be poisonous."

Liu Xinyue looked at this pile of things, and really did not want to study it anymore. He did not know who had refined this poison, and did not have a single hint of beauty in it. If he used this thing, he would be able to tell that there was a problem just by looking at it, okay?

Based on her many years of experience as a doctor of poisons, she knew that the first step of refining poisons was to make them into beautiful shapes. Of course, this was from her own aesthetic perspective, and the second step was to concoct poisons that were no different from ordinary things.

It could be toothpaste, medicinal herbs, water, etc. As long as it was something that could be used on a daily basis, no one would be able to discover it!

The poisons that Liu Xinyue had refined were all the same as the first type, they were all powdered, and were much easier to use.

Later on, the powder would be refined into the shape of a medicinal pill. Moreover, this kind of medicinal pill would melt the moment it came into contact with water.

Of course, it could also be used to refine the poison into a liquid form. However, preserving this kind of liquid poison was more troublesome. Moreover, the stronger the poison, the easier it was to vaporize the poison if it was not properly preserved.
