The shopkeeper's words made everyone quieten down one after another. They all looked at him, waiting for him to reveal the specific toxins and antidotes of the three poisons.

After saying that, the shopkeeper walked down to the first veiled lady's side. At the same time, he placed the papers with the antidotes written by the doctors back into the tray.

"Alright, please look at me now."

After doing all this, the shopkeeper picked up the bowl of poison from the first tray and began to slowly introduce it.

"Everyone, let me announce the name of this first type of black poison. It is called Night of Darkness."

Dark night?

Liu Xinyue was startled when he heard the name, the name of this poison was pretty literary.

If she named it based on her habits, it would be like giving the poison its corresponding name. However, she could learn how to use a name like this to emphasize her literary skills. This way, others might not know what it was.

"It can't be that the night is dark because of the first poison, right?"

Chen Jiamu who was at the side also ridiculed this strange name that had nothing to do with poison.

"Shopkeeper, why is it called the pitch-black night of the poison?" Someone immediately asked.

"Hehe, this is what I'm going to explain to everyone."

When the shopkeeper heard this, he first chuckled to tell the person not to be impatient, and then he began to introduce this first poison, the pitch-black night.

"First of all, literally, this dark night is because the poison is black."

With that, the shopkeeper tilted the bowl of poison in his hand and showed it to everyone.

Then, listening to him continue, "Secondly, the night is often reminiscent of something frightening and frightening, and it makes it easier for people to do bad things in the dark."

"Everyone, look here."

With that, the shopkeeper picked up another small spoon and began to stir it slowly in the pitch black night, as if he was looking for something.

Seeing this, Liu Xinyue guessed that the shopkeeper was looking for the red granules inside the black powder.

As expected, just as she thought this, the shopkeeper scooped up a bit of the black powder from the spoon. Then, he put his hand on the clean gloves and slowly scattered them among the scooped up black powder.

"Alright, I wonder if any of you have noticed anything different in here?"

The shopkeeper raised the spoon in his hand high up and slowly moved it in front of everyone. His movements were very slow, so that everyone could see clearly.

Some of the guests who were seated at the back could not help but walk forward and surround the shopkeeper to watch from a closer distance.

The shopkeeper told them to return to their seats after they had all finished looking through it.

"Innkeeper, is it still the same as before?" Why didn't I see any difference? "

"That's right, shopkeeper, isn't this the black powder? Is there anything else in it? "

Some people who didn't pay too much attention stood up, indicating that they didn't notice any difference.

"I saw it!" When I walked up to it just now, I noticed that there were actually some red granules within the black powder. "

Just as some people were questioning this, those seated in the back, who had come forward to take a closer look, stepped forward and announced the results of their observations.

"However, because those red granules are really too small, and also require a long time to see, it's normal that you guys didn't see them."

When everyone heard this, they immediately understood why some people didn't see it while others did.

"What this young master said was not wrong, what I wanted everyone to see was the red particle inside the black powder."

The shopkeeper listened and nodded. He then took a white cloth from a servant girl and placed the white cloth in both of the servant girls' hands. Then, he poured the black powder from the spoon onto the white cloth.

After that, the shopkeeper placed a small bowl under the white cloth and had the maidservants slowly move the white cloth back and forth.

Following this action, everyone could see black powder start to fall out from the bottom of the white cloth.

Seeing that, Liu Xinyue immediately understood what the shopkeeper was doing.

"Mistress, this subordinate doesn't understand. What is the shopkeeper doing?"

Ya Er came over to ask Liu Xinyue.

"The shopkeeper is currently filtering the black powder."

After Liu Xinyue heard this, he explained to Ya Er, "Look, as the servant moved back and forth, did the black powder fall out?"

"Yes, Mistress." Ya Er nodded, but what did this filter mean?

"But, Ya Er, you're looking, even though the black powder on the white cloth is decreasing, some of it still stayed there?"

Liu Xinyue continued to point at the white cloth and said.

"That's right, Mistress, on that white cloth …" It doesn't look like the original black powder? " Ya Er looked carefully and noticed that the black powder on the white cloth seemed to have turned red?

"Take a closer look. What exactly is that thing?" Seeing this, Liu Xinyue did not say it out loud, but asked back.

There were some things that could not be said by Liu Xinyue himself forever. He needed Ya Er to observe and think about on his own so that he could improve his own abilities even faster.

Otherwise, not only would Ya Er's abilities not improve, he would also have a habit of relying on himself. If something were to happen in the future and was not by his side, then what would happen?

"Seems to be so... That red particle? "

Hearing that, Ya Er nodded, then started to observe again.

Previously, when the servant was filtering the black powder, it was not very obvious, but now that much time had passed, Ya Er was able to see it more carefully.

With a single glance, he realised that the things left on the white cloth were the particles.

"That's right, the shopkeeper's actions were to filter out these red particles from the black powder." Nodding his head, Liu Xinyue quickly explained, "The reason he is doing this, is also to let us see these red particles more clearly."
