The shadow stone of the immortal cultivation world left behind is a high-definition stereoscopic image, which is really not comparable to the photo function.

But there's more to a phone than just a camera function.

Tang Yan took out his mobile phone again, turned around, and took a video.

"The shadow stone that my father said is more similar to the function of this video."

A high-definition photo, Emperor Zhaoyuan was just a little surprised, but this video was completely beyond his imagination, and he was shocked.

"But that's not all." Tang Yan made a call to Emperor Zhaoyuan and taught Emperor Zhaoyuan how to connect, "This call function is a bit similar to the sound transmission of thousands of miles, even if you are thousands of miles apart, you can hear each other's voices as if you were facing each other." ”

"What an artifact!" Emperor Zhaoyuan couldn't help but sigh.

Tang Yan shook his head: "Although the function is powerful, the production method is quite simple. I see that my father and emperor have worried a lot about the queen mother's post-sealing ceremony, so my daughter is willing to give away 10,000 mobile phones. When people everywhere can use mobile phones, some unimportant government affairs can be handled through mobile phone calls, which greatly reduces the workload of the emperor. ”

Emperor Zhaoyuan's eyes lit up.

Although he saw his mobile phone for the first time today, as an emperor, his political sense of smell was quite sensitive, and when he heard Tang Yan say this, he thought a lot.

The call function is more than just a substitute for some of the twists!

Mobile phones can transmit sound for thousands of miles and are of great use for the exchange of information.

In the future, people in remote areas will also be able to use mobile phones, and everyone will exchange information, and there will be no more deception.

As an emperor, I am afraid of being deceived by my subordinates.

Therefore, the emperors of previous dynasties will establish organizations similar to Dongchang Jinyiwei and other organizations as the eyes and ears of the emperor

Now that he has a mobile phone that can transmit sound for thousands of miles, wouldn't he have countless miles of ears and eyes.

I have to say that Emperor Zhaoyuan thought about his mobile phone too amazingly.

Deception is not something that can be solved by a small mobile phone.

It's just that when I first came into contact with such an artifact, I lost my previous caution for a while.

However, it cannot solve all the deceptions.

But where the disaster is affected in the place, where there are any major events, it really can't be hidden from the emperor's eyes.

Tang Yan had been an emperor before, so he could almost know exactly what Emperor Zhaoyuan was thinking?

She turned on the Weibo function again and taught Emperor Zhaoyuan how to use it.

Although Emperor Zhaoyuan was in contact with this kind of new gadget for the first time, he got started quickly, and he registered an account with the help of Tang Yan after a while.

Tang Yan also helped Emperor Zhaoyuan apply for certification.

Since Weibo has not been changed, Tang Yan has no way to set his account as the main account.

But the certification is an inherent function, and I don't know which god certifies it, but it's amazing, the certification is passed.

I saw that the account reads - "Emperor Zhaoyuan of Qi State".

Tang Yan also taught Emperor Zhaoyuan how to use the handwriting function of the input method, and asked Emperor Zhaoyuan to use his own clockwork Weibo.

Emperor Zhaoyuan was rarely a little cramped: "Let's not send it first." ”

Tang Yan doesn't care about this: "It's okay, I just want to tell my father that this thing called Weibo can be registered as a personal account, and then post information on it, which can communicate information better than the phone function." ”

Weibo, a portal site, is still different from the function of taking pictures and making phone calls, and the ancients never even imagined it, which is completely beyond the cognitive range of Emperor Zhaoyuan.

Seeing that Emperor Zhaoyuan was a little confused, Tang Yan continued: "If you want to convey any decrees in the future, you can't send them through Weibo. If there is a disaster in the local area, literate people can take a picture and post a Weibo, and you will know when the time comes. Compared with a phone call that focuses more on personal calls, Weibo is more in line with what you think, and you don't have to be afraid of being deceived. ”

Emperor Zhaoyuan didn't have time to be surprised, why did Tang Yan know what he was thinking, but began to imagine that in the future, when the decree was reached, the country's national strength would definitely go to a higher level.

Those big countries have Xiuzhen sects behind them, so there is no need to think about it. But the surrounding small countries will not be able to be included in their own sphere of influence?

The more Emperor Zhaoyuan thought about it, the more excited he became, and he couldn't wait to let everyone use their mobile phones now.

Tang Yan nodded with satisfaction.

It's good, now someone has helped promote it for free!

In fact, there are many other uses for mobile phones, but those uses are difficult to attract an emperor, so Tang Yan will not say anything, but directly hand over a storage bag to Emperor Zhaoyuan, which contains 10,000 mobile phones.

Looking at the piece of mobile phone in the storage bag, Emperor Zhaoyuan could not hide his excitement.

"That's more than enough! It can be issued to all those who have made more than one meritorious person! ”

Tang Yan waved his hand magnificently: "You don't have to be so selective. During this time, I will refine some more, and strive to give you another 100,000 units before leaving. ”

The population of the whole country is only a few million, and Tang Yan made 100,000 units as soon as he made a move, which made Emperor Zhaoyuan excited.

The previous investment of just 20 spirit stones has reaped hundreds of times the harvest!

Because of the sufficient number of mobile phones, Emperor Zhaoyuan first sent one to the harem concubines and the big eunuchs and palace maids with heads and faces, and then to the officials and their families in the capital.

Tang Yan was very enthusiastic about teaching a few clever palace maids in Su Rou Palace how to use them, and let these palace maids teach others.

And the official in the court, Tang Yan appeared in the early dynasty and personally taught everyone how to use it.

That proactive energy, Emperor Zhaoyuan was moved.

I didn't expect this daughter, who had never been close to him since she was a child, to be so concerned about his affairs.

More than 10 days passed quickly.

After Tang Yan participated in Su Rou's post-sealing ceremony, after helping the original owner's mother to support the scene, he handed Emperor Zhaoyuan a storage bag and mobile phone, and left the palace, ready to return to the sect.

The great business of selling mobile phones in the mortal world, with the help of Emperor Zhaoyuan, a free tool man, is estimated to need to ferment for a period of time.

Tang Yan just took advantage of this time to return to the cultivation realm and continued to sell mobile phones in the cultivation realm.

According to the rules summarized by the previous crossing.

The number of mobile phones that need to be sold to complete the pre-human manifestation is closely related to the protagonist's experience.

Yun Yi has been in both the cultivation realm and the mortal world, the latter for a long time and the former for a short time.

There is a high probability that mobile phones will be popularized on a large scale in the mortal world, but there must also be a certain number of people in the cultivation realm who use mobile phones.

It's just that with Tang Yan's current cultivation, it's still not enough to see in the cultivation realm.

So on the way back to the sect, Tang Yan deliberately took a long detour, passing by a place called Fang Tian Secret Realm.

Fang Tian Secret Realm is also called Fang Tian Jedi, and the people who enter it are almost dead.

But if you can come out of it alive, there will definitely be a qualitative leap in strength.

At that time, Tang Yan can reasonably reveal the cultivation of the Jindan period.

Standing beside the secret realm, Zhou Jingru grabbed Tang Yan uneasily.

"Senior sister, be careful! There's a Jedi ahead, just take a look at it and don't accidentally step into it! ”

Tang Yan nodded: "Senior brother, don't worry, I won't die like this!" ”
