Zigui opened the two bags separately.

Set aside a portion of the tobacco and set it on fire.

"The nicotine in this brand is a bit heavier than that in normal tobacco. ”

Zigui lit it again, and the tobacco in the other bag: "This is what my brother smoked that day, I can't be wrong, I can distinguish the taste in it." He must have smoked a lot in his room that day, and it was still in the absence of air circulation. ”

"Do you know what's added to this?"

Zigui frowned: "Similar to nicotine, but definitely not nicotine." I remember that some time ago, Uncle Lin bought those medicinal herbs had this taste, at that time I thought it was nicotine, but later I found out that it was just two things that tasted similar, but their effects were completely different. ”

"What is added to He Ziheng's smoke is just a spice. Jiang Beichen said: "It is a kind of hallucination that can make people, and it is recorded in the book that it is called phantom incense, which is a synthetic spice." In ancient times, this kind of thing was used to interrogate prisoners and Qinglou. ”

"Is there anything in common between these two places?" Zigui couldn't understand.

"Depending on the dosage used, they produce different effects. Jiang Beichen explained: "In ancient times, it was used on prisoners to make them fearful. It is used in the Qinglou, and it is mostly used on those women who do not want to be trapped in the Qinglou. ”

"Hallucinations. Zigui thought carefully about the events of that day: "My brother, he didn't have any hallucinations. ”

The facts in front of him were consistent with what he had in mind. Jiang Beichen was very serious: "However, you have hallucinations. ”

Zigui immediately understood what he was referring to.

Then I thought of Gu Yutong's words last night.

"It has been proven that this spice does not cause any damage to the functioning of the human body. After the intervention of fresh air, people will also recover little by little. ”

"So that means that my brother has been targeted for a long time. Zigui's eyes were full of worry: "I remember that Brother Ziheng is not a smoker, and it was the first time I saw him smoking at Daddy Jiang's house that day." I don't know when it started. ”

There is another possibility, Jiang Beichen had a guess in his heart, but in order to avoid Zigui being sad, he didn't say it after all.

He suspected that He Ziheng had added something to the tobacco himself, in order to fulfill himself.

"It's possible what you're talking about, but there's no evidence to show it. ”

Zigui didn't answer, and always felt that there were still some things that were not right.

And it's also very important.

"What are you thinking?" Jiang Beichen asked.

"I can't tell. Zigui frowned and looked at the cigarette he had lit just now: "It also has an ingredient, which is very light and light." There should be, but I'm not sure. Or the ingredients in the original cigarettes, but one of them is a little thick, and it is not certain. ”

"In this way, we can directly test the things for testing, which is more accurate. Make your own comparison table of ingredients. Just test what you've learned over the past few days and see how much you can master. Jiang Beichen put away the things and contacted Uncle Lin, and soon someone came and took the things away.

At this time.

The doorbell rang, it was the courtyard gate.

Zigui thinks that there are very few guests in the house.

"Who are you looking for?" opened the door from the family's aunt Sister Hong.

"Does Qiu Zigui live here?"

Zigui listened carefully in the room, and this was very familiar: "Yes, is it Meng Laozi?"

Zigui was startled, turned around and walked out of the room.

Sure enough, it was Meng Lao.

Jiang Beichen went out with Zigui.

Zigui asked Sister Hong to leave.

looked at Meng Lao.

"Why are you here. Zigui looked unwilling: "It's not that it can't be good." ”

"......" Old Man Meng immediately took out a mask and put it on: "You see I'm preparing a mask, except for you, no one in your family will recognize me." I'm careful. ”

"!!" Zigui blinked with glasses, and there were three words written on the mask [Ignore me]

Zigui couldn't cry or laugh, this old man is too cute.

Suddenly realized that I was too much: "I'm sorry, I'm just a little nervous." ”

"It's fine. Master Meng asked, "Can I go in?"

Zigui didn't dare to let Meng Lao come to the house, so he thought about it and asked quietly, "Have you seen each other?"

Meng Lao understood that Zigui was referring to her mother Qiu Xinya: "There should be none." ”

"What should be?" Zigui felt that he couldn't be.

"I don't think she can remember me. Meng Lao said with certainty: "I saw her when I was very young, and she was not in elementary school at that time. I haven't seen him since, so much so that I never knew about his relationship with your dad. Later, after investigating you, I found out that it was her. ”

Beichen reminded in a whisper: "When Meng Lao was young, he and your grandfather were also gentlemen's friends. ”

Zigui squinted at Jiang Beichen: "You know?"

"Yes!"

Look at Meng Lao again: "You also know?"

"Hmm. ”

"Why don't you say it?" Zigui's gaze swept back and forth on the faces of the two people.

Meng Lao didn't say that it was forgivable.

But Jiang Beichen didn't say it, and Zigui felt that he couldn't forgive.

It just so happened that it was a little rude not to let Meng Lao enter the door, but now Jiang Beichen and Meng Lao should be fine together.

So he decisively annoyed his face and directly pushed Jiang Beichen out of the courtyard gate.

"Do some introspection and see what you did wrong. After Zigui finished speaking, he directly closed the courtyard door and turned back to the house.

The two people outside the door, big eyes look at small eyes, old eyes look at tender eyes.

Rather speechless.

Jiang Beichen felt so wronged, but Meng Lao laughed happily.

It seemed that Zigui's refusal to let him in did not affect Meng Lao's mood at all.

"Who does the son belong to?" Qiu Xinya heard the sound of talking outside.

"Looking for Beichen. Zigui said naturally: "They have something to talk about, so they went out." ”

"Really?" Qiu Xinya wondered, "How did I hear someone asking your name just now?" ”

"That's right. Zigui smiled and said, "Mom, this is my home, not Beichen's home." When you find this, you naturally want to ask my name. ”

"Yes. Qiu Xinya asked again: "That dinner, should we also prepare Beichen and his friends." ”

"Beichen said that we would eat outside, so let's wait if we don't have to. ”

"Good. ”

The two people outside the courtyard gate heard the conversation between the son and the mother and daughter clearly.

Jiang Beichen looked at Meng Lao in a good mood: "Zigui just doesn't want you to go to her house, so I have to cooperate with Zigui to stop Meng Lao from entering the door." ”

"!!" Meng Lao looked disgusted: "What's there to be sorry about, you don't listen to my granddaughter differently, this time you don't even have a place for dinner." ”

Jiang Beichen had to admit that this was the case.

It was already past 5 p.m., and the sun was still so big.

Jiang Beichen was already cold and not afraid of the heat, but Meng Lao couldn't bear it: "Let's go, my old man will dry up in a while, and my precious granddaughter will definitely not be able to spare you." ”
