Saiba said listlessly: "A semi-finished product that I used to toss out casually, no, to be precise, a scrap." At that time, there was a breakthrough in the mining technology of the tribe, and a strange ...... was found deep in the crust of the Hengya Mountains Ore?well, it can't be said to be an ore, so far everyone has not fully studied its properties, just call it a strange stone. Because it's like life, it's been emitting a strange signal-like fluctuation, and all the exotic stones have this intrinsic connection with each other. ”

"Then what did you do with this thing?" Nian Yubai interjected.

"I used to think that since these strange stones will transmit signals to each other, wouldn't it be very convenient for two people to hold a piece and clearly know each other......'s location? The Hankor of the clan also tried to transform it, but in the end they all failed. ”

"I think this is very interesting, why don't we think about this?" Nian Yubai suddenly came to his senses.

Saiba rolled his eyes and said, "Han Ke has given up this research, what tricks do you think we can come up with?"

"Young man, I want to seriously criticize you on this point, although you can endure loneliness and engage in research with peace of mind, but you are too superstitious to believe in authority, as soon as you hear that the letter can be done, you subconsciously choose to give up, why don't you challenge yourself?"

Saiba said unconvinced: "Challenge yourself to seek truth from facts, and besides, it's not that I haven't thought about it, it's really not good." ”

"Ouch, doesn't that mean we can't do it?" Nian Yubai took the small box made of strange stones seriously, pretended to be like a god stick and muttered some nonsense, and then suddenly stretched out his hand and pointed to a corner of the room, and said confidently: "Is there another strange stone there?"

Saiba opened his mouth wide and said with a face full of disbelief: "You, you, you...... How do you know? You're not blindsided, are you?"

Nian Yubai directly moved the cabinet in the corner of the room, and took out a dusty black-brown stone from the bottom, with a villainous face: "How?"

Saiba's whole body froze in place.

Yu Ling really couldn't help but dismantle the stage and said: "Okay, don't pretend, if you use soul power to sense, our big gang of people will be able to." ”

Nian Yu Bai Deng's face was resentful.

"Soul power, what are you talking about?" both Tando and Saiba were at a loss.

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

"Wait for me to do an experiment," Yu Ling suddenly looked up at Nian Yubai: "You, go out, go wherever you go, and leave here five hundred meters away." ”

"What are you doing?" Nian Yubai was stuffed with another strange stone in his hand, and his face was full of confusion.

"If you want to go, you can go. ”

Nian Yubai left the room with the strange stone for some reason, and then walked farther and farther away under the eyes of everyone, until he came to the street outside.

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

"How do I know where I am, I'm going to get lost after turning several streets......" Nian Yubai's soul thought was clearly transmitted through the strange stone, with a little complaint.

The next moment, his words came to an abrupt end, replaced by a strange cry: "What the hell? this, this is already beyond the range of our soul power sense, how can I still hear you?"

Yu Ling ignored it: "You go further." ”

It's been a long, long time......

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

"I can still listen to it. ”

"I'm almost out of Skyflame City, even if it's more than twenty kilometers in a straight line, right?"

"It's only more than 20 kilometers. ”

"Just?!You tell me clearly!"

When Nian Yubai ran back out of breath, everyone in the house was still confused, not knowing 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 reluctantly used as the first generation of mobile phones." ”

"What the hell is a cell phone?"

"I don't understand, it's normal not to understand. ”

Yuling turned his head to look at Saiba and Tando, pondering and said: "I think this is very valuable for research, but there are currently two difficulties, one is how to make it accessible to ordinary people without soul power, and the other is the problem of distinguishing the signals of different strange stones, I have a little idea, but it still needs to be practiced." ”

"It's okay, there's still a month, let's take our time!" Nian Yubai felt like 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 clan, but also for the Terran race.

......

The evening of the seventh day of May in the Terran calendar.

Yu Ling came to the top platform of the Huoluo Tower alone, and there was silence around him, only the vast night that was as cool as water.

He took out a small black and brown inconspicuous square box from the spirit ring, and gently pried open the lid of the box, revealing a colorful star, neatly arranged in an orderly manner, but there was still a large blank space underneath.

Yu Ling lightly pressed on a small star, and a strange fluctuation rippled, and after a murmur of unknown meaning, it gradually condensed into a clear voice: "Hey, Ah Ling?"

"How's it going? can you hear me?" said Yuling to the small box.

Nian Yubai said with some excitement: "Of course I can hear it, then don't talk about it, I'll ask the others how it is." ”

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

After trying more than a dozen people one by one, Yuling closed the small square box and exhaled softly.

In the past month, the last experiment was finally successful, and they were all ready, and if they didn't debug everything by the last minute, they would have to do it in a few days.

Either way, a mature work is more striking than a half-finished product with a lot of problems.

Looking at the inconspicuous box in his hand, Yu Ling couldn't help but feel a dreamlike sense of absurdity and stunned in his heart, as if he couldn't believe that it only took them a short month to get out the research results of those people on the earth for several years and decades from scratch.

Of course, this is also due to the special features of this world, although many things here seem to be particularly backward, but the cultivators of the three major systems have a lot of unique advantages.

At least the soul power at their fingertips easily replaced electronic technology and satellite signals, and the properties of the Strange Stone itself also contributed to it, in fact, what they actually did was not that complicated.

Because under the detection of soul power, it is easy to find the different fluctuations of each strange stone, so it is not difficult to distinguish the work, and the characteristics of the strange stone itself can accommodate the soul power, with Nian Yubai's transformation formation, each strange stone is not only a system of its own, but also can transmit signals to each other under the connection of the same series of formations, and is under the domination of a large system network.

During this period, there were many problems in the deployment of the formation system, and they often interfered with each other and fell into a state of disorder, I have to say that Nian Yubai spent a lot of effort in this regard, and almost created a series of formations by himself, before this problem was finally solved. So Yu Ling sometimes felt that he didn't help much, and only occasionally put forward some opinions and suggestions, but everyone agreed that he was the biggest hero.

After all, to a certain extent, if it weren't for Yuling coming up with this idea, the Strange Stone Walkie-talkie would not have appeared in this world at all.

That's right, it's a walkie-talkie, Yuling originally called it a mobile phone, but it was unanimously opposed by everyone, thinking that the name was strange and unpleasant, Yuling had to retreat to the second, although everyone was also dissatisfied with the walkie-talkie, but it revealed the main function, and a group of people who couldn't think of a good name for the time being could only reluctantly accept it.

Whoever made them think of those names made people vomit blood even more, what strange machines, soul power machines, communicators, it sounded like some fake and shoddy stalls.

Fortunately, although the process did not go smoothly, there was finally a satisfactory result.

"Let's go, let's go to the Lanla Hotel tonight, drink a hundred barrels of fire wine from him, and don't get drunk and don't go home!" Tando ran up to the platform at the top of the tower, and a large number of people had gathered behind him.

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

It's a day to look forward to.
