Chapter 390: Wrong direction!

The reason why Xu Wen swore to come to such a conclusion is mainly because the purification rate will not have much impact on the production of pencil lead.

Moreover, after baking at such a temperature for nearly an hour, even if the highest purification rate is not obtained, at least the overall graphite powder has changed.

Relatively speaking, this can be regarded as a manifestation of the success of purification.

To be honest, Xu Wen also felt that after this high-temperature purification, these graphite powders had indeed undergone slight changes.

Just like what the little monkeys said before, it feels like the color of these graphite powders has become deeper, that is, it has become darker.

Although, these cannot be used as criteria to judge whether the purification is successful, or even, it may be a psychological feeling.

"Looking at the monkey group's current performance, it means they have completely succeeded!"

"That's right. It seems that the monkeys are not pursuing sophisticated equipment, but things that are used daily!"

"This means that our initial guess was wrong."

"But what are the things we use every day that are related to graphite?"

Seeing the monkeys constantly celebrating each other, the audience in the live broadcast room immediately came to the final answer.

At the same time, they are also full of more intense curiosity about what the monkey group is about to make.

"Boss, now that the graphite powder has been purified, what should we do next?"

After a while, the monkeys calmed down slightly from their extremely joyful mood.

You know, graphite purification is just one step in making pencils.

"Next, according to Hou Er's arrangement, make all these pen holders as quickly as possible!"

"Hou Da, bring me the sulfur you brought back."

"Monkey Three, stir the gum that Monkey Two brought back as much as possible to increase its viscosity."

After saying this, Xu Wen directly picked up the freshly baked graphite powder and walked towards the corner of the camp.

On the other hand, Monkey 2 is constantly guiding these novices.

Although it may take a certain amount of time in training and other aspects in the early stage, in the later stage, this kind of time investment can definitely be turned into very generous returns.

Monkey Three, on the other hand, looked at the snot-like gum in his hand with a look of disgust.

Although these gums already have a certain thickness, constant stirring can make them more vigorous with each other, thereby increasing the viscosity of the gum itself.

"What are the monkeys planning to do? Why are they attacking these trees again?"

"If you really want to guess the true intentions of the monkey group, you should be able to roughly guess it through the behavior of these little monkeys."

"Now is the time for everyone to brainstorm. You can think about what is related to our daily life, and it is also related to trees and graphite."

Looking at the busy figures on the screen, it seems to provide certain clues to the audience in the live broadcast room.

Xu Wen, on his side, was also constantly fiddling with the graphite powder he had on hand, as if he was studying their properties.

"Boss, this is the sulfur you want."

At this time, Hou Da came over with a puzzled look on his face. He was very confused as to what the function of sulfur was.

You know, the previous purification process was to completely eliminate some unwanted impurities, but now that sulfur is added, isn't it just superfluous?

"Are you very confused as to why sulfur is needed?"

After receiving the sulfur, Xu Wen used his iron sword to crush it into fine powder without raising his head.

"That's right, boss, I really don't understand what this step is about."

After hearing Xu Wen's words, Hou Da nodded very honestly and directly expressed the doubts in his heart.

"To be honest, I'm not very clear about what role sulfur can play."

"I'm just following the general process of making pencils now."

"However, I think these sulfurs are similar to other alternative materials, such as clay. They are mainly used to bind all the graphite powder together."

After saying this, Xu Wen had completed all the work at hand.

"Then why don't we use clay?"

At this time, Hou Da was like a bully. All the questions he asked were to satisfy his curiosity, rather than some truly meaningful and valuable questions.

"You!"

After hearing this question, Xu Wen immediately laughed, glanced at Hou Da helplessly, and then said without looking back: "It's not because I don't have clay!"

"Now I am holding my breath and cannot say a word!"

After saying this, Xu Wen carefully mixed the graphite powder and sulfur powder together.

"Professor Lu Yu, I wonder if Xiao Jin's exposure to graphite powder without any protective measures will have an impact on his health?"

Looking at Xu Wen, who was very cautious, Julie seemed to have seen some issue that needed to be understood in depth.

"To be honest, the mineral graphite itself is not toxic and will not have any impact on our health."

"However, graphite in powder form is completely different. Although it is not toxic, if it is inhaled into the body through the respiratory tract, it will still have some effects!"

These words can also completely explain why Xu Wen made the monkey hold his breath when mixing the two powders.

"Find me some water and bring it over!"

When the powder floating in the air had almost dissipated, Xu Wen spoke first and said to Hou Da.

The next step is to fuse these two substances together to form an existence similar to mud.

"Boss, we're done here, can you see if this level of thickness is okay?"

On Monkey 2's side, he has also completed his task, and more than sixty pen holders are neatly displayed on the ground.

"That's pretty good. The next step is to boil these pen holders in water!"

These pen holders are continuously cooked with hot water, mainly to soften the fibers of the wood.
