Pale green, green ...... Soon, it changed to a color similar to iron blue. In this way, the changes in their faces after being poisoned with Lu Peng were also confirmed.

Yang Fan took a light breath again, and after confirming that this toxin had nothing to do with the smell, Yang Fan breathed a sigh of relief.

The poison that Lu Peng and the others are in now is the mixed poison produced after the Eight Treasure Rabbit Ding and the black bone soup are mixed together.

And it was when Yang Fan confirmed this that Old Man Bai called Yang Fan.

"Gastric lavage is useless. ”

"Well, I guessed it. If it was a poison that would be useful for stomach washing, they wouldn't use it on Old Man Xiao. ”

"How's your investigation going?"

"I'm sure it's a mixture. But I'm still looking into the specific situation. ”

"Poison?"

"Well, it's a mixture. To put it simply, two originally non-toxic things are mixed together to create a new toxin.

In many costume film and television dramas, there are similar plots, and in fact, this situation does exist in reality. Today, the Xiao family is here, that is, there is a problem with the black bone soup and the eight treasure rabbit ding.

The four poisoned ones have all been exposed to this dish and soup.

But I have to carefully understand what special ingredients are added before I can start detoxifying."

On the other end of the phone, Bai Chong frowned. "Well, you get busy first, and Cheng Hu and I will talk about it first, so that they don't worry too much. ”

After hanging up the phone, Yang Fan walked out of the storage room. "Let's talk about the specific ingredients of the two dishes, black bone soup and eight-treasure rabbit dice. ”

Lao Qin didn't dare to hide anything, but after Lao Qin finished speaking, Yang Fan couldn't help frowning.

No, there is no mixing in these materials.

Traditional Chinese medicine has similar sayings such as "eighteen antis", "nineteen fears" and so on, which means that there will be a reaction after these are mixed. Yang Fan is very familiar with these contents, and even knows some situations that are not recorded in ordinary medical books.

But all these things that Yang Fan knows are not consistent with today's situation of black bone soup and eight treasure rabbit ding.

What Yang Fan saw with his own eyes was indeed that the black bone broth and the Eight Treasure Rabbit Ding were mixed together to form a mixture. But the materials that Lao Qin said did not produce mixed poison.

Yang Fan instantly thought about whether someone would add other materials to it to cause this to happen.

However, what is it exactly? Yang Fan is very confident in his sense of smell, and it stands to reason that Yang Fan can recognize ordinary medicinal materials.

Could it be something that is colorless and odorless, but can be mixed with other materials?

Yang Fan frowned, and his head began to think quickly. Yang Tianyi seemed to have said a similar situation to Yang Fan before.

Just when Yang Fan's attention was highly concentrated, Yang Fan suddenly heard a collision sound in the distance.

Yang Fan stood up with some confusion and walked out of the kitchen. The voice came from the living room, and Yang Fan walked over to the living room. It may be a housekeeper, but it's better to make sure.

Yang Fan cautiously lowered his footsteps, but the moment he walked out of the corridor, he still took a look at the people in the living room.

Yang Fan didn't know if it was a coincidence, or if the other party heard his footsteps, so he could only walk to the living room at this time.

The housekeeper didn't know where he had gone, but in the living room was a woman in an apron.

Yang Fan remembered that she was one of the cooks who helped bring the soup to the table before. The woman who is close to thirty years old seems to be called Liu Ying. The corners of his mouth were slightly upturned, and he always gave Yang Fan a very polite feeling.

Seeing Yang Fan's appearance, Liu Ying paused, but there was no obvious change in her expression: "Mr. Yang." ”

"Hmm. Yang Fan bowed his head and asked casually. "Where's Steward Zhao?"

"I don't know, I didn't see it. I just came in, ready to go back to the house and rest for a while. ”

Yang Fan glanced at Liu Ying, a little suspicious. Before he settled Steward Zhao and stared at the living room, it stands to reason that Steward Zhao would not leave easily.

And now that Steward Zhao is gone, Liu Ying just happened to appear here. Yang Fan couldn't help but have a trace of doubt.

"Is there anything Mr. Yang needs my help with?"

Yang Fan shook his head, and after Liu Ying said goodbye to Yang Fan, she walked to the passage at the other end of the living room. If Yang Fan remembers well. The Xiao family lives in a side house in that direction.

Although Yang Fan still has doubts, he can't just follow people inexplicably, right?

After Liu Ying left, Yang Fan turned around and walked in the direction of the kitchen again.

However, as soon as he walked to the kitchen door, Yang Fan suddenly frowned.

The housekeeper just walked away, it can be a coincidence, and it is normal for Liu Ying to want to rest at this time.

However, the two things happened to come together, and just now, Yang Fan couldn't help but still have some doubts.

And now, Yang Fan has thought of another situation.

Yang Fan frowned and returned to the living room. As soon as he entered the living room, he heard the sound of footsteps coming from the passage that Liu Ying had passed through before.

Yang Fan was more determined and quickly took a few steps. Without much movement, he gently came to the corner of the living room.

Holding his breath, he sat down on a chair in the corner and looked in the direction of the passage.

The other party had already tried very hard to lower his voice, but the Xiao family was so quiet now, it was very obvious.

Liu Ying walked to the intersection and looked left and right with some caution. Because of the angle, I didn't see Yang Fan in the corner on her right.

Seeing Liu Ying's cautious appearance, Yang Fan was already completely sure that Liu Ying had a problem.

Then, Liu Ying took two steps forward, and subconsciously glanced to the right, only to see Yang Fan, who was sitting in the corner very leisurely, looking at her with some amusement at this time.

"Mr. Yang. Are you still there?" Liu Ying paused, "I lost my key." Then he pretended to bend down and pick up the key.

After getting up, he took the key out of his pocket and shook it at Yang Fan, and quickly wanted to turn around and leave.

"Alright, don't move. Are you interesting?"

Yang Fan shouted to stop, Liu Ying hesitated, and finally stopped what she was doing. turned around, but still looked innocent: "I don't know what you mean, Mr. Xiao." ”

Yang Fan smiled: "You are going to rest, and the room is indeed in that direction."

I don't know much about the rules of the Xiao family, but even ordinary restaurants and restaurants have dedicated staff channels.

There are obviously other roads outside, but you, as a member of the Xiao family, go directly across the villa. This situation is not appropriate, is it?"

"Old Man Xiao doesn't care about these details. ”

Even if the Xiao family doesn't say it, this is also a conventional rule that the Xiao family should consciously abide by.
