There are about a hundred jade talismans in total, and each one has some aura flickering, and the presence of aura means that the refining is successful and there are no problems.

Dan Chengzi chuckled: "It seems that I am good at alchemy. Even when it comes to refining artifacts, I have begun to draw parallels..."

"..."

Lin Fan ignored him, but took a piece and examined it carefully.

Strictly speaking, these sound-transmitting jade talismans are all 'child talismans'. They cannot be directly interconnected with other 'child talismans', but can only contact the 'mother talisman'.

And ‘child and mother’ are also easy to distinguish.

To put it simply, a certain immortal cultivator refined many jade talismans and sent them to friends and others so that they could contact him through the jade talismans.

However, these friends cannot communicate with each other through their own jade talismans.

This is the difference between 'son and mother'.

The mother symbol can contact any sub-symbol, but the sub-symbols can only contact the mother symbol.

These hundred or so jade talismans are all child talismans. As for the mother talisman, they are naturally controlled by the sky-gazing mirror weapon spirit.

From then on, it is equivalent to a server, responsible for processing information between many sub-symbols, allowing sub-symbols to communicate with each other...

This is the prototype of the Internet.

Although there are few functions, the current ones that can be used are basically communication, but this is just a test. After it can be done, Lin Fan will continue to find ways to improve it and add various functions.

Once the functions have been increased to almost the same level, it’s time to start promoting it throughout the Holy Land.

As for the entire world of immortality?

Lin Fan couldn't make up his mind at this moment. He still knew only a little about the Zifu Holy Land, let alone the entire Holy Land. Blind Ji's tyrannical plan was one of the most stupid behaviors.

How to do it specifically will be discussed later.

The boat will naturally go straight when it reaches the bridge.

"Let's try it. I hope it will work."

Lin Fan poured his true essence into the jade talisman, and the sound transmission jade talisman instantly lit up, giving it a hazy beauty.

All of this seems much simpler than running the modern Internet, but in fact, it is much more difficult.

Just the Emperor's Sky Observation Mirror and its weapon spirit... This is enough to make 99.99% of people dare not even think about it.

And even now, Lin Fan can't guarantee 100% success.

Because the 'data interaction' between sub-symbols and parent symbols is definitely no problem, but for the interaction between sub-symbols, although there is a tool spirit as a 'server' to relay, it is necessary to distinguish who each sub-symbol represents...

This is also very difficult!

You can only rely on the weapon spirit to identify the subtle differences in each person's true energy, and then make the right choice...

Can she do it?

Lin Fan didn't know.

At this moment, it is time to test whether the instrument spirit of the Sky Observing Mirror is as powerful as the legend.

"Take a piece and try it."

Lin Fan spoke.

Dan Chengzi didn't hesitate, he took a piece directly and infused it with real energy.

Immediately, Lin Fan activated the sound transmission jade talisman and called Dan Chengzi...

Didi didi.

The very familiar button sound came from the jade talisman in Dan Chengzi's hand, and Lin Fan was delighted.

"Preliminary test successful!"

After the beeping sound, since Dan Chengzi is still paying attention to Zhenyuan, 'communication' is established!

"Your Highness?"

He spoke, but his own voice came from the jade talisman in Lin Fan's hand, startling him: "This???"

"Zi Fu can also communicate with each other?"

"But Your Highness, this doesn't seem to be necessary... right?"

In Dan Chengzi's view, it is actually not difficult to make Zifu also have the function of transmitting sounds to each other, but it is not necessary, so no one develops it.

"No need? It's so necessary!"

Lin Fan slowly shook his head, and his words came out from the jade talisman in Dan Chengzi's hand.

"etc!"

Dan Chengzi's expression changed, and he looked at the jade talisman in his hand as if he had seen a ghost: "This...???? is not a sound transmission, but????"

How to describe this phenomenon?

He couldn't understand...

"instant messaging."

Lin Fan's lips curled up slightly.

Now this function is not like the Internet, but like an old mobile phone that only has the function of making calls?

But...this is just one of the functions.

"Next try to deliver the image!"

After Lin Fan disconnected his true energy, he re-infused it and activated the 'photography' function in the formation.

But with the help of Qi Ling, this is not a photo shoot, but a 'video chat'!

And it’s 3D video chat!

After Dan Chengzi connected, a reduced version of the 3D image of the two people appeared on the jade talisman. Although it was only a few inches long, it was the same as them at the moment!

"What now?"

Qi Zixiao opened his mouth, and the sound came from his mouth and the jade talisman almost at the same time. Even the 'villain' opened his mouth, as if the villain was speaking directly, which made Dan Chengzi feel like he had seen a ghost.

“Your Highness, what are you doing????”

"As you can see."

Seeing Dan Chengzi's heartfelt shock, Lin Fan couldn't help but smile.

Done!

At least for now it's done.

As for the specific success, it still needs to be tested, because currently only Lin Fan and Dan Chengzi use the jade talisman, so the weapon spirit should not need to judge who is who, as long as the two people's data can be interacted in real time.

So after there are too many people, can we still accurately find the person the user wants to contact?

Or, after the amount of data increases, can the device spirit still transmit data accurately and instantly?

Thinking of this, Lin Fan couldn't help but take a look at the seemingly ordinary and simple sky-viewing mirror on his waist, but found that it was still simple and ordinary, as if nothing had happened.

"It seems that it is just one-to-one data transmission, which puts almost no burden on the weapon spirit. Then, it is time to test again..."

Lin Fan thought for a while and said: "Dan Chengzi, take ten jade talismans and give one to the divine fortune teller, and give the rest to your trusted senior brothers."

"I will conduct a series of tests later. You can also test each other. You also know the formations and who you need to contact. Just recite it silently in your mind when infusing the true essence. Of course, the premise is that the other party has

Jade Talisman."

A hundred or so yuan, if all were distributed, would be enough for the 'first internal test'.

But Lin Fan was not going to be so exaggerated at the beginning. Dan Chengzi divided it into more than a dozen pieces, and when he returned and added the guardian disciples, it was basically enough to complete the first internal test.

As for why you should give the fortune teller a piece...

Ahem, Lin Fan was afraid that he would not be able to think about it. After all, he was using the best refining virtual pills and the Great Evolution of Heaven and Earth, and he was tricked by that tiger bitch into practicing the Fiery Eyes and Golden Eyes...

"Your Highness, don't worry, Dan Chengzi will fight to the death to complete the mission."

Dan Chengzi patted his plump chest until it crackled.

Lin Fan: "..."

"I'll leave first."

With a wave of his long sleeve, many sound-transmitting jade talismans instantly flew into the opened storage bag. Immediately, Lin Fan left the alchemy room and headed towards Haoyue Peak.

After Lin Fan left, Dan Chengzi was astonished, his face full of amazement.

"Your Highness is going to make some big noise again!"

"First it was the heavenly merits and the sky-viewing mirror, but now it seems like..."

"However, this sound transmission jade talisman is really good. You can actually see what the other party is doing."

"Then if I communicate with Junior Sister Yun while she is taking a bath..."

"Wonderful~!!!!"
