In fact, Lu Ping had discovered this the last time he was in the Heavenly Court.

Although the immortals knew the function and uses of a cell phone, there was still no such thing as using a mobile phone in the Heavenly Court.

Perhaps many people had experienced it or used it.

The Heavenly Court did not have the corresponding infrastructure.

Even if they were immortals, under such circumstances, they could only use people to inform others or use some spells to communicate.

The convenience was far inferior to a cell phone.

It was the same with the new space that Yun Xiao had created.

Although the immortals did not deliberately stay too far away, if they really wanted to inform a certain immortal alone, they still needed to send people to inform them.

Yun Xiao began to think.

Bi Xiao laughed and said, “I told you that I should have gotten some signal towers or something like that in the Heavenly Court a long time ago. My sister insisted that I not tell the Jade Emperor about it. It was so boring! I could only play around in the Primal Chaos Universe. The Dao ancestor was the same. After getting the Primal Chaos Universe, he didn’t even consider getting some interesting entertainment sections.”

“Shut up!” Yun Xiao berated.

Bi Xiao was really lawless. No one dared say that.

Bi Xiao pouted and said, “That’s what it is. Even if the Dao ancestor knew, I would dare to say that this is a reasonable feedback.”

In reality, most of those immortals only wanted to be meritorious, but not to make mistakes.

No one mentioned this to the Jade Emperor.

Lu Ping was speechless. The dao ancestor’s Primal Chaos Universe was really awesome. It ignored spatial distance and perfectly connected the Three Stages.

If it charged a fee and made a profit, it could completely defeat all the operators.

In fact, some human planets could also communicate across planets.

However, the delay in communication signals, including the loss of information, was very unstable. It was also very difficult to achieve technological breakthroughs.

After all, the distance between planets was still very far.

If one wanted to use electromagnetic signals to pass through space nodes and achieve stable transmission, it was simply impossible with the current technology.

Therefore, interstellar communication was usually done in the early stages between some large news media.

Special cultivators were sent to deliver messages to the planet.

However, the time delay was also very terrifying. The speed of electromagnetic signals in the vacuum was similar to the speed of light.

In other words, they could only communicate in some places that were “not far” from each other.

This was, of course, in a universe that was easily measured in light years.

However, Hong Jun was, after all, Hong Jun. The Primal Chaos Universe could communicate indiscriminately.

Ever since the birth of the Primal Chaos Universe, the interstellar service in the universe had truly become a reality.

Therefore, apart from fighting, many people were also interacting with information in the Primal Chaos Universe.

To put it simply, the information of their home planet was transmitted to other planets through the Primal Chaos Universe in time.

Even the interstellar purchase service for universe treasures was the same. The product information was shared between the Primal Chaos Universe. Once someone bought it, they could send it by interstellar mail.

Of course, interstellar purchases might take a long time.

Fortunately, cultivators had long lifespans, so they could basically afford to wait.

However, it had to be said that the Primal Chaos Universe did not have any achievements in the entertainment sector.

There was no such thing.

Yun Xiao berated Bi Xiao and then looked at Lu Ping with a smile. “Your suggestion is good. I think it’s fine, but how do you want to build it?”

Lu Ping smiled. “Just leave it to me.”

“Leave it to you? Then what are your conditions?” Yun Xiao asked with a smile.

Lu Ping’s face stiffened. “What conditions can there be? Madam Yun Xiao, helping Mengyao rebuild her body was a great help to me. This is something that should be done!”

In fact, he had already considered it.

It was better to return the favor as soon as possible.

Building this signal facility was considered a favor.

What was needed to build the infrastructure? It was just star dollars.

To Lu Ping, star dollars was just a number.

Of course, this number was built on the foundation of Huang Xiaoqi’s substantial financial resources.

But speaking of which, there were actually many people on the sect’s account.

The last assessment still used a fee system.

The money received had not been used up.

Using star dollars to repay a favor was a good deal.

Moreover, Lu Ping had his own considerations.

If Sun Wukong and Kong Xuan were by his side, they came with a clear purpose.

Yun Xiao, on the other hand, was more of a normal interpersonal relationship.

Having a relationship with such an expert was undoubtedly beneficial to him.

This was especially so for Yun Xiao. As the actual manager of the southeast star domain, Fengming Planet would be under his control in the future, and his own sect would be one of them as well. No matter how one looked at it, it would be appropriate to befriend her.

Hearing Lu Ping’s words, Yun Xiao revealed a smile from the bottom of her heart.

“Not bad, really not bad.” Yun Xiao had a better impression of Lu Ping.

She said softly, “Then I’ll have to trouble you.”

“Alright, I won’t say anymore. Uncle Sun, Mengyao, and Yun Ying, we’ll go back to Fengming Planet first.” Lu Ping chose to take his leave.

Yun Xiao didn’t ask him to stay.

Sun Wukong led the three of them to the space node with a somersault. In the next second, both parties appeared outside Fengming Planet.

Following that, another few somersaults followed. The next second, the three of them appeared directly above Binhai City.

Sun Wukong smiled and said, “Alright, I’ll be leaving first. You guys can go back on your own.”
