"Toxic particles? Aren't these things already filtered out by our filter? How could they be the culprit for limiting the number of times a gas mask can be used?"

"That's right, boss. Doesn't filtering mean that it has disappeared?"

"Boss, we still don't quite understand this place!"

Just through these three or two sentences from the monkey group, Xu Wen understood why these little monkeys didn't understand what he just said.

To put it bluntly, in their view, so-called filtration is not just about making toxic particles disappear from the air.

At the same time, after filtering, they are like lost lives, without any trace of their existence in this world.

"First of all, you have to understand one thing."

"The so-called filtration only makes these toxic particles disappear from the air."

"It's not that they disappear from this world."

"Think of it, these filtered toxic particles will all be attached to the filter material."

"Think about it, when the toxic particles attached to the filter material reach a certain level, what will happen if you continue to use it?"

When he said this again, Xu Wen directly did some small experiments in order to make the monkeys understand more thoroughly.

He first took a handful of relatively fine soil in his hand, and then very slowly and evenly sprinkled it on the area that had just been wetted by the moisture in the filter material.

As a layer of sand was sprinkled down, it was full, and the moisture in the ground completely wetted the sand.

In this link, Xu Wen mainly simulated the situation of the filter filtering toxic particles.

Later, Xu Wen no longer spread the sand evenly and slowly, but directly sprinkled all the sand in his hands on the ground.

Since the moisture contained in the land is limited, the sediment scattered on the ground this time did not gradually become wet like before, but instead remained in its original state.

"Boss, will it cause those toxic particles to accumulate in the filter for a long time?"

"If we continue to use it under this situation, it is very likely that the filter will have no effect."

"As a result, will it cause us to directly inhale toxic gases?"

After thinking carefully for a while, a little monkey said suddenly.

"Yes, this is why gas masks cannot be used for an unlimited period of time."

"So, even if we have the protection of gas masks, it does not mean that we are not in danger."

"On the contrary, we must leave these toxic gases as quickly as possible!"

These words can be seen as Xu Wen's warning to the monkeys. After all, he never saw this happening.

"Boss, we understand!"

"In other words, even with gas masks, our lives are not 100% safe!"

To be honest, Xu Wen did not explain an important reason why gas masks cannot be used for a long time.

Rather, it is because when a gas mask filters poisonous gas, it cannot 100% guarantee that there will be no toxic particles in the oxygen in the respiratory tract and lungs.

You know, even the gas masks produced by human society with the current technology cannot meet such standards, let alone their somewhat "shoddy" products.

"Professor Lu Yu, Xiao Jin seemed to have stuffed something into the cylinder just now."

"What do you think his purpose is?"

Looking at Xu Wen's operation just now, Julie asked with some confusion. Not only him, but also some viewers in the live broadcast room found it difficult to connect these completely unrelated things.

"To be more careful, what Xiaojin stuffed into the container just now has two parts. One is relatively moist, as everyone has seen, and the other is relatively dry."

"However, the two parts use almost the same things."

Looking at his screen, Lu Yu recalled in his mind what materials Xu Wen used just now.

"If you don't count the cotton, these two parts add up to a total of six layers."

"The materials of these six layers, from outside to inside, are sand, charcoal powder, and cotton."

"This should be done to filter out magazines or something like that!"

After Lu Yu listed all the materials, a picture instantly appeared in his mind.

This basic method of filtration should have been taught by the chemistry teacher in middle school and high school.

Generally, this is mainly used to filter impurities in water sources.

Therefore, Lu Yu's remarks directly misled the thinking of all the viewers in the live broadcast room.

"In that case, it should be used to filter the water source. After all, the air in their place doesn't seem to need filtering!"

"Is there something wrong with the water source around the monkey camp? Or is it polluted?"

"However, if it is contaminated, certain symptoms will definitely show up in the monkeys."

"What you said upstairs makes sense. These little monkeys now seem to be healthier than us."

"But if not to filter the water, what are they doing this to filter?"

After thinking about it, the audience in the live broadcast room felt that apart from filtering water sources, this filtering device had no other use at all.

What's more, the air quality in Longguo Wildlife Park can be regarded as one of the few high-quality places in the entire world.

However, the next scene completely shattered everyone's suspicions.

"Boss, the resin has been completely collected!"

"They are still in liquid form. If they are used to make the "lenses" you mentioned, they seem to need solid ones!"

After driving in front of Xu Wen, Hou Er said with some worry.

Although he didn't know what the "lens" Xu Wen mentioned looked like.

However, Xu Wen has said before that all these things must be carried on the face.

If it were liquid resin, how could it be worn on the face?

"Yes, that's the state!"

"We still need to process these resins. In their current state, they certainly cannot be used immediately."
