"However," Jin Ling stared at Liuyun with a relieved face, "I was relieved to see that Senior Brother you played a group of bear children around." ”

Liuyun Khan: Your junior brother is also a person who has raised more than 30 children, and taming a group of second generations of immortals is not a piece of cake.

"Oh, by the way, junior brother," Our Lady of the Golden Spirit turned her head to glance at the little demon who was cleaning in the courtyard, "how did you contact your subordinates the other day?" ”

"Communicator!"

Seeing the Holy Mother of Jin Ling staring at her with a confused face, Liuyun patted her thigh, reached out and took out a square jade talisman from her sleeve, and handed it over.

"This ......," Our Lady of the Golden Spirit looked curiously at the jade pendant in her hand, "how should this thing be used?" ”

"It's similar to the usage of jade pupils," Liuyun smiled and took out a jade pupil of the same style from his sleeve and swept it with his divine sense......

"Yikes!"

The Holy Mother of Jin Ling, who was looking at the jade pupils, was surprised to find a line of words on the jade talisman.

Our Lady of Jin Ling, who has always shown a cold image, showed a little fan girl-like worship in her eyes: "Senior brother, this is also amazing!" ”

Liuyun scratched his head innocently: "It's okay!" ”

"By the way, junior brother," the Holy Mother of Jin Ling rolled her eyes and asked Liuyun with a frown, "In a few days, I will return to Heaven, and this communication talisman should be useless, right?" ”

Liuyun thought for a moment and nodded: "It stands to reason that it should be useless, Heavenly Court and the four continents are not in the same space, and the formations arranged in the communication talisman cannot pass through the space, but ......"

Our Lady of Jin Ling gradually dimmed, her eyes regained her brightness, and she stared at Liuyun with joy: "Senior brother, do you have a way?" ”

"Yes, yes," Liuyun frowned, "However, it will take a little time to study. ”

"How long?"

"A few days as short as a beard, or a few months as long."

Hearing the time limit given by Liuyun, Our Lady of Jin Ling breathed a sigh of relief: the most important thing that immortals lack is time, and moreover, one day in heaven and one year on earth......

Then, the Holy Mother of Jin Ling, who had planned to return to Heaven immediately, stayed in Fangcun Mountain for a while longer.

And Liuyun, who received a request for the development of cross-border communication symbols, seems to have returned to those years of burning passion, and he doesn't sleep for ten days and half a month at every turn.

However, cross-border communication has always been a problem, and even in the interstellar era that Liuyun has experienced, cross-border communication is not time-sensitive.

At that time, many people complained that the so-called cross-border communication was like a manual wiring phone before the invention of program control: if you have a phone at home, you can count it as rich if you can make a call, but when you can receive the phone on the other end can only depend on luck.

Moreover, even the ultra-quantum communication that was so angry at that time could not solve the communication delay caused by the time and space barrier......

Many problems that can't be solved by cattle people, Liuyun is naturally powerless; And right now, the problem facing Liuyun is even more severe: there is more than one layer of space between heaven and earth.

In order to be able to research cross-border instant messaging technology as soon as possible, Liuyun racked his brains, just to improve the timeliness a little bit, so he studied the concentric contract on his body inside and out......

However, after the concentric contract crosses the border, it only has the ability to vaguely transmit the emotions of the contractor.

Of course, when studying the concentric contract, Liuyun is not without any gains: there are some things in the concentric contract that have the ability to synchronize across borders.

But when Liuyun felt that there was something wrong and went back to study the concentric contract again, the more he studied, the more confused he became: the magic of the concentric contract is not in the contract itself, but in the moment when the contract was formed......

The trail is broken again.

Originally, Liuyun planned to ask the master for advice on where the crux was, but when Liuyun rushed to Lao Dao's room, the door was wide open, and there were only the four swords of Zhuxian who had disappeared for a while in the room......

"Is there something wrong?" Zhu Xian saw that Liuyun's face was haggard, his steps were hurried, and he was a little curious, "The eldest master has gone far away, and it will take a while to come back." ”

"Oh......"

Liuyun nodded stupidly, and turned to leave. 52 Literature

"Hey, I said that the fifth junior brother, when we met, I didn't even say hello?"

Faced with Killing Immortal's accusation, Liuyun had no choice but to turn around and give Killing Immortal a smile that was more ugly than crying.

"As for it," seeing Liuyun's dejected face, Killing Immortal's face turned black directly, "I don't owe you any money!" ”

"That's it!" As the eldest brother, Zhu Xian couldn't let Liuyun and Killing Immortal pinch each other, so he naturally had to stand up and solve the siege, "Liuyun, what kind of problem are you encountering?" ”

Liuyun smiled bitterly and nodded: "That's the ......"

Liuyun told Zhu Xian about the problems he encountered.

After hearing this, a mysterious smile appeared on Zhu Xian's little face.......

As soon as Liuyun saw Zhu Xian's posture, he knew that this guy might have a solution, so he looked at Zhu Xian with a smile on his face: "Brother, do you have a way?" ”

Zhu Xian nodded meaningfully: "So to speak." ”

"Tell me, brother?" Liuyun grabbed Zhu Xian's arm, "I'm in a hurry to use it?" ”

Seeing Liuyun's anxious look, Zhu Xian was embarrassed to buy Guanzi anymore, and looked at Liuyun with a smile: "Actually, you have to thank me for this." ”

"Big brother, don't sell it, right?"

Liuyun almost knelt down.

"Okay," Zhu Xian smiled slightly, "Do you remember how we came to the Central World?" ”

Liuyun was still a little puzzled: "Time and space turbulence! ”

"I remember that before you came here, you were already a serious immortal, right?"

"That's right!"

Seeing Zhu Xian staring at him with a smile, Liuyun was still confused......

"I remember you had an ID card in your hand, right?"

Liuyun suddenly realized, staring at Zhu Xian with wide eyes: "Why did I forget about this?!" ”

After speaking, Liuyun took out his all-in-one ID card.

After that, Liuyun didn't care about the four swords of Zhuxian, so he ran away......

Seeing Liuyun's figure disappear into the corner of the wall in a hurry, the killing immortal pouted dissatisfiedly: "What kind of person! ”

Zhu Xian smiled slightly: "Bet, this guy will come back!" ”

After returning to his "laboratory", Liuyun couldn't wait to fix the ID card to a specific fixture, and then penetrated his senses......

A few minutes later, Liuyun sat down in his chair in despair.

In the past, Liuyun was not cultivated enough, there was no way to parse the magic circle and runes on the ID card, and he didn't know what secrets were hidden in the ID card; At present, Liuyun's cultivation is high enough, and when I look back and study, I have the sigh that the sea was once difficult to water.

Of course, just the magic circle and runes are not enough to destroy Liuyun's three views, what really shocks Liuyun is the principle of cross-border communication, which is exactly the same as the super quantum communication he has been exposed to.

Moreover, the ID card made the use of something similar to the super quantum make Liuyun feel that the world has collapsed......

"The world is so big, there are no surprises!"

Liuyun shook his head with a wry smile, hesitated again and again, and then got up from the chair, came to the experimental table again, and sent out his divine sense: in Liuyun's induction, a small thing in the shape of a broken paper was lying in the eye of the cross-border communication array.

In order to test the characteristics of the little thing, Liuyun entered a message into the ID card.

After receiving the message, the end of the little thing, which was similar to a broken paper, vibrated in an inexplicable rhythm......
