After all, the communication facilities Xu Wen wants to build need to be used within the entire camp.

If the bamboo is too thin, the effect of collecting sound or expanding sound may be greatly reduced.

However, if it is too thick, it will easily cause wrist soreness, which is somewhat contrary to the original intention of "convenience" in the first place.

Therefore, it is this kind of bamboo, neither thick nor thin, that best meets Xu Wen's initial expectations.

"Boss, I don't know if these hemp grass are enough!"

Just as Xu Wen kept picking up the bamboos, Hou Er and the others also returned to the camp.

However, what is different from Hou Da's group of monkeys just now is that everyone in Hou Er's group is holding a lot of hemp in their hands, which even blocks their sight.

"Enough, these are definitely enough!"

Looking at the hills of hemp grass in the hands of those monkeys, Xu Wen felt like he couldn't laugh or cry.

Not to mention that these hemp grass are enough for this production task, the remaining ones can even circle the entire camp!

At this time, the monkeys who went to look for shells also returned to the camp, but the shells in their hands were all of the same color.

This does not mean that shells only exist on the seashore. In some small rivers, these shellfish also exist.

Of course, these shellfish in the river are generally called river mussels, and the colors on the shells are relatively simple.

However, these things are not originally used for decoration, so you don't need to care too much about whether their colors are bright.

"marvelous!"

"Next, you follow my instructions and operate step by step!"

Xu Wen came up with this idea after seeing that the monkeys had not only been able to expand the entire city wall without his own guidance, but also ensured that the stability would not be affected in any way.

You know, in the past, it was Xu Wen who gave demonstrations and explained each step.

But now, Xu Wen wants to improve his guidance and make it truly centered on the monkey group.

It can be said that under the influence of this brand-new method, it is not only a test for the entire monkey group, but also a great progress!

The most important thing is that this method can, to a certain extent, enable the entire monkey group to have a very deep understanding of every process of construction, and eventually reach the point where they are thoroughly familiar with it!

"Huda, you are responsible for the processing of these bamboos!"

"First, you need to cut these bamboos according to their bamboo joints, and then trim them to a length of fifteen centimeters!"

"After each bamboo is trimmed, use the sharp tools in your hands to drill a small hole at the bottom of each bamboo that can allow the hemp rope to pass through!"

"Secondly, drill a hole of the same size in the middle of each bamboo tube!"

Xu Wen first explained some basic operating steps to Hou Da and others in detail. After all, bamboo can be said to be the most important material in the entire manufacturing process.

"Monkey Two, you process these hemp grass!"

"Just like our previous steps, we also rolled all the dried hemp grass into hemp ropes one after another!"

"It's just that this time we must be as careful as possible!"

"Also, the length of each hemp rope should best meet the interconnection length of each household!"

"Monkey Da, when the time comes, you will cooperate with Monkey 2 and the others to determine the size of the holes at the tail of each bamboo tube!"

You know, according to Xu Wen's vision, these devices must be connected to every household.

That is, just like the phones we used before, every house has a phone line!

"All you have left is to divide these shells. It is best to have five shells per household!"

"After you finish this job, you can go help other monkeys!"

Immediately, Xu Wen looked at the third group, which was also the group with the easiest task among the entire monkey group.

In fact, these shells are the devices Xu Wen uses to replace current telephones or cell phone "ringtones"!

If anyone needs to make a call, they only need to move the hemp rope to cause the shells to shake.

Just like a wind chime, it constantly produces sounds to remind this family!

In just a few minutes, Xu Wen explained all the basic steps.

The next time is mainly the time for the monkey group to make.

Of course, throughout the entire process, Xu Wen was only in the position of a guide.

If the monkey group encounters any difficulties, Xu Wen can provide corresponding guidance.

"What are Xiaojin and the others making?"

"It seems that the materials used are not very complicated, and there are not many types. It shouldn't be too difficult to make anything!"

"After putting these materials together, why did the shape of a bucket appear in my mind?"

"Hahaha, the people upstairs are laughing so hard at me!"

"Why didn't you say that Xiao Jin and the others mainly wanted to make a wine glass?"

"By the way, haven't you noticed that the monkey group has now formed a brand-new education model?"

"Huh? What you said upstairs is really accurate. This teaching model seems to be student-centered in the true sense."

Looking at the busy monkeys who are enjoying themselves, the audience in the live broadcast room are not only guessing what the thing that is about to be made is.

At the same time, some education major viewers in the live broadcast room even discovered a new direction.

It's just that this discovery didn't arouse the ideas of many viewers?

"Professor Lu Yu, in your opinion, what is the invention of the monkey group this time?"

At this time, Julie had already formed images of countless objects in her mind.

But not surprisingly, these speculations were overturned by him almost immediately.

"Hahaha, this is really hard to guess!"

"I feel that now everyone in our audience has at least one answer guess in their mind!"

"However, I think this time's stuff shouldn't be too complicated. As I told the audience before, the raw materials this time have already determined the difficulty this time!"

After Lu Yu thought about it carefully, he said with some uncertainty.

Although there are only three raw materials, hundreds or even thousands of possibilities appear in the eyes of the viewers in these live broadcast rooms!
