Zhang Yifan heard the shouts of the stable women, and saw that Zhu Di and the others were also nervous, so he knew that they had misunderstood, and hurriedly explained: "I didn't say that you were poisoned, this disinfection is just such a mention, to be precise, it is to eliminate some microorganisms, and these microorganisms may be bacteria or viruses." ”

It's okay if he doesn't explain, but when he explains, everyone is confused and even more incomprehensible!

Zhu Jingjing first came back to her senses and asked curiously, "What is Xijun?" What is Soldier Poison? ”

Someone asked first, and everyone else stared at Zhang Yifan, wanting to hear what kind of statement he would have for this strange formulation?

Zhang Yifan looked at Zhu Jingjing, who was asking, and immediately explained to her: "These are all very tiny creatures, which cannot be seen with the naked eye. People and animals get sick, and food spoils, etc., in fact, it is all related to them! ”

"Huh?" Zhu Jingjing didn't expect that after asking, not only did she not understand the question she asked, but became more confused: What is this talking about? Why do you not understand it the more you listen?

So, she hurriedly confirmed: "Really? ”

Zhu Di, who was on the side, had a serious expression, and also asked: "Since you said that you can't see it with the naked eye, how do you know?" It can't be that you're not mortal, right? ”

The crown princess didn't speak, but her expression was also very puzzled, a little confused, feeling that the fairies and monsters were about to come out?

Aunt Liu on the side, her eyes widened at this time, looking at Zhang Yifan, she was a little convinced, this Zhang Wazi, who grew up watching from a young age, is not really a fairy, right? Otherwise, how to explain what is happening these days?

Zhang Yifan looked at their expressions, a little crying and laughing, but it was also in his expectation. So, he didn't answer Zhu Di's words directly, but asked again: "Then do you think that in this air, I mean that there is nothing in the air in front of any of you, or will there be something?" ”

Hearing his question, almost everyone couldn't help but look at the corns and carefully looked at their eyes.

Or did Zhu Jingjing respond first: "Of course there is nothing?" What else could there be? ”

Zhu Di didn't respond so quickly, because he intuitively felt that there was something in Zhang Yifan's words, and there should be something in this invisible air. Even he felt that the invisible thing that Zhang Yifan mentioned before might be in the air.

Thinking so, although he didn't speak, he listened carefully with his ears pricked up.

The others were actually similar, all looking at Zhang Yifan and listening to what he was going to say.

I saw that Zhang Yifan did not answer immediately, but turned around and walked into the house.

The crown princess and the others were sitting under the eaves, and when he walked into the house, he actually walked towards the crown princess and them.

Zhu Jingjing saw it, a little inexplicable, and suddenly blushed, and she didn't know what she was thinking.

However, Zhang Yifan did not stop in front of them, but walked into the house.

At this moment, everyone was dumbfounded, not knowing what the hell he was doing?

Zhu Di immediately frowned, and was about to follow up to take a look, but heard Zhang Yifan greet him inside: "You all come in!" ”

When Zhu Jingjing heard this, she immediately took the crown princess's arm and stepped into the threshold first. When Zhu Di saw it, he immediately followed.

Wen Po in the courtyard, you look at me, I look at you, after a little hesitation, I followed in.

In the house, I saw Zhang Yifan standing inside and greeted the people who had just entered: "Come here, stand here, and then look at the sunlight shining in from the window to see if you find anything?" ”

His house can really be said to be surrounded by walls. Inside, there was no furniture except a bed.

At this time, Zhang Yifan was standing by the window. His window, which was not papier-mâché, was only sealed with a large wooden plank, but it was leaking. The sun was shining through those cracks.

Hearing his words, Zhu Jingjing immediately took the crown princess over first, and according to Zhang Yifan's instructions, stood on the side of the light, and observed carefully.

In other words, without looking closely, Zhu Jingjing suddenly exclaimed in surprise: "It turns out that there is dust in the air!" Wow, it's all flying, what a surprise! ”

The others listened, stood at a good angle, and looked with their hearts, and naturally they all saw it.

Zhang Yifan said with a smile at this time: "There is dust in the air, which is actually a very understandable thing, why the tables and stools will be dirty after a long time, this is the reason." It's just that in the past, we didn't think about them and observed them carefully! ”

When the crown princess and others heard this, they were all surprised.

And Zhu Di was thoughtful, and then asked Zhang Yifan: "Are you using this to prove that what kind of disease-causing thing you said before exists in this air, and you can't usually see or touch it?" ”

"That's right, that's what it means!" When Zhang Yifan heard this, he immediately nodded and said, "Those germs are much smaller than this dust, and you have to use tools to see them!" ”

When Zhu Di heard this, he immediately asked, "What tool?" ”

"Come on, let's go outside and talk, I'm not used to having too many people in the place where I sleep!" After Zhang Yifan finished speaking, he walked out first.

The princess listened, looked into the room, but did not speak, and walked out.

Zhu Jingjing looked at the bed, blushed again, and immediately went out.

After returning to the courtyard, Zhang Yifan continued the topic just now: "In fact, there is also a microcosm that accompanies us in the past. The microbes are too small to be visible to the naked eye and have to be seen with the help of tools. However, we cannot ignore the impact of these microbes on our lives. ”

Zhu Di instinctively felt that this tool was very important, so he wanted to ask what tool it was, but Zhu Jingjing asked first at this time: "Then what should we do?" I feel uncomfortable at the thought that there are things around me that can make people sick! ”

As soon as they heard her words, all of a sudden, everyone had this feeling, and their expressions were very unnatural.

Zhang Yifan listened to it, saw their appearance, and couldn't help but smile and said: "Don't worry, we humans and microorganisms have existed for tens of thousands of years, under normal circumstances, don't worry." A simple example, if you touch bad food, it will not affect you, but if you eat bad food, it will have an effect, right? ”

Hearing this, everyone breathed a sigh of relief as soon as they thought it made sense.

However, Zhu Jingjing immediately spoke: "Then as soon as I speak, this mouth, won't the bad things in the air enter my stomach?" ”

When she spoke, she went to cover her mouth.

When the others heard this, their faces suddenly changed, and those who wanted to speak suddenly shut up.

Zhang Yifan listened very helplessly, he just wanted to explain the microorganisms, but it turned out to be such a situation, he was really speechless!

In fact, it is very easy to understand that when a new world is just opened, the impact on the ancient people is definitely very big!
