Saiba said listlessly: "It was a semi-finished product that I tossed out in the past. No, to be precise, it was a waste product. At that time, the clan's mining technology made a breakthrough, and a strange... ore was discovered deep in the crust of the Hengya Mountains? Uh.

, it cannot be said that it must be an ore. So far, everyone has not fully studied its properties, so we just call it a strange stone. Because it is like a living thing, always emitting a strange signal-like fluctuation, all strange

There is this inner connection between stones.”

"Then what did you originally do?" Nian Yubai interjected and asked.

"I used to think that since these strange stones can transmit signals to each other, wouldn't it be very convenient for two people to clearly know each other's position if they hold one each? But then when I started actual research,

It was discovered that the fluctuations sensed by strange stones are not distinguishable at all, which means that as long as others have strange stones, you can feel them, but this is meaningless... The Hanke people in the clan have also tried to transform,

But they all failed in the end.”

"I think this is very interesting. How about we just think about this?" Nian Yubai suddenly became energetic.

Saiba rolled his eyes and said, "Hanco has given up on this research, what else do you think we can come up with?"

"Young man, I want to severely criticize you on this point. Although you can endure loneliness and do research with peace of mind, you are too superstitious about authority. As soon as you heard that Han Ke Jiada couldn't be done, you subconsciously chose to give up. Why not

Challenge yourself?"

Saiba said unconvinced: "You must be realistic when challenging yourself. Besides, it's not like I haven't thought about it before. It's really not possible."

"Oh, if you can't do it, doesn't it mean we can't do it?" Nian Yubai seriously picked up the small box made of strange stones, pretended to be like a magic stick and muttered some random words, and then suddenly reached out and pointed to a corner of the room, full of confidence.

Mandi asked: "Is there another strange stone there?"

Saiba opened his mouth wide and said with disbelief: "You, you, you...how do you know? You are not deceiving, are you?"

Nian Yubai directly moved the cabinet in the corner of the room and took out a dusty dark brown stone from the bottom. He said with a triumphant face: "How?"

Saiba's whole body froze in place.

Yu Ling couldn't help but said: "Okay, stop pretending, if you use soul power to sense it, a lot of us can do it."

Nian Yu Baideng immediately had a look of resentment on his face.

"Soul power? What are you talking about?" Tando and Saiba both looked confused.

Yu Ling took the small box and strange stone from Nian Yubai's hand, integrated the soul power into it and quietly sensed it for two seconds, and his expression suddenly became a little weird.

"Wait a minute, let me do an experiment," Yu Ling suddenly raised his head and looked at Nian Yubai: "You, go out, go wherever you want, five hundred meters away from here."

"What for?" Nian Yubai had another strange stone stuffed into his hand, his face full of confusion.

"Just go if you are told."

Nian Yubai left the room with the strange stone without knowing why, and then walked farther and farther under the eyes of everyone, until he reached the street outside.

After a while, Yu Ling integrated a ray of soul thought into the strange stone and said, "Where are you now?"

"How do I know where I am? I turned several streets and almost got lost..." Nian Yubai's soul thoughts were clearly transmitted through the strange stone, with a bit of complaint.

The next moment, his words stopped abruptly and was replaced by a strange cry: "What the hell? This, this, this has long been beyond the range of our soul power induction. How can I still hear you?"

Yu Ling ignored it: "You go further."

A long, long time passed...

"Aling, can you still hear me?" Nian Yubai's voice was a little vague.

"I can still listen to it."

"What the hell? I'm almost out of Tianyan City. Even the straight-line distance is more than twenty kilometers, right?"

"It's only over twenty kilometers."

"Just?! Tell me clearly!"

When Nian Yubai ran back panting, everyone in the room was still confused as to what the two of them were doing.

Yu Ling put down the small box made of strange stones and said calmly: "After the identification, it can be used as a first-generation mobile phone."

"Cell phone? What the hell?"

"Don't understand? It's normal not to understand."

Yu Ling turned to look at Saiba and Tando, thinking: "I think this is of great research value, but there are currently two difficulties. One is how to make it available to ordinary people without soul power, and the other is to distinguish between different

Regarding the issue of strange stone signals, I have some ideas, but they have yet to be put into practice."

"There's still a month left, let's take our time!" Nian Yubai felt that he was witnessing a major historical moment.

In fact, the day when the strange stone walkie-talkie was officially launched a month later did become an extremely important anniversary, not only for the Li Yan tribe, but also for the human race later.

…

The evening of May 7th according to the human calendar.

Yu Ling came to the top platform of Huoluo Tower alone. The surroundings were silent, only the vast night was as cold as water.

He took out a dark brown inconspicuous small square box from the spiritual ring, and gently opened the lid of the box, revealing a patchwork of colorful stars inside, arranged neatly and orderly, but there was still a large blank space below.

Yu Ling gently pressed on a small star point, and a strange wave rippled out. After a burst of unexplained noises, it gradually condensed into a clear voice: "Hello, Aling?

"

"How is it? Can you hear my voice?" Yu Ling said to the small square box.

Nian Yubai said excitedly: "Of course I can hear you. Let's not talk about it. I'll go ask the others how they are doing."

"Okay." Yu Ling pressed the star again and ended the conversation.

After trying more than ten people one by one, Yu Ling closed the small square box and breathed out gently.

In the past month, they have been working hard and slowly. The last experiment was finally successful. They were all ready. If they didn't debug all the problems at the last moment, they would still have to go up in a few days.

But no matter what, a mature work is always more eye-catching than a half-finished product with lots of problems.

Looking at the inconspicuous box in her hand, Yu Ling couldn't help but feel a dream-like sense of absurdity and astonishment, as if she couldn't believe that they only used a short month to destroy those people on the earth who had lived for decades.

The research results have been produced from scratch.

Of course, this is also due to the special features of this world. Although many things here seem particularly backward, the practitioners of the three major systems have many unique advantages.

At least the soul power at hand can easily replace electronic technology and satellite signals, and the characteristics of the strange stones themselves are also indispensable. In fact, what they really do is not that complicated.

Because under soul power detection, it is easy to detect the different fluctuations of each strange stone, so it is not difficult to distinguish, and the characteristics of the strange stone itself can accommodate soul power. With Nian Yubai's conversion formation,

Each strange stone not only forms its own system, but can also transmit signals to each other when connected with the same series of formations, and is under the control of a large system network.

During this period, many problems arose in the deployment of the formation system, which often interfered with each other and fell into a state of chaos. It has to be said that Nian Yubai spent a lot of effort in this regard and almost created a series of formations to finally solve this problem. So Yu

Ling sometimes feels that he has not helped much and only occasionally made some opinions and suggestions, but everyone agrees that he is the biggest contributor.

After all, to a certain extent, if Yu Ling had not come up with this idea, the strange stone walkie-talkie would never have appeared in this world.

That's right, it's a walkie-talkie. Yuling originally called it a mobile phone, but everyone was unanimously opposed. They thought the name was strange and unpleasant. Yuling had to settle for the next best thing. Although everyone was also dissatisfied with the walkie-talkie, at any rate it

The main function was revealed, and a group of people who couldn't think of a good name for the time being could only reluctantly accept it.

The names they thought of made people vomit blood even more. Strange machines, soul machines, and communicators all sounded like fake street stall goods.

Fortunately, although the process was not smooth, there was finally a satisfactory result.

"Let's go to Lan La Hotel tonight and drink a hundred barrels of fire wine until we get drunk!" Tando ran up to the top platform of the tower, and a large group of people had gathered behind him.

Tomorrow is the official registration day for all levels of theoretical and technical tests.
