"Also, don't forget to go to Tianzhu and ask them to sign the Dongtu trade contract. If you make up for this, the entire Dongtu trade circle will be complete."

The autumn sun is still very hot. Zhao Xu wiped the sweat beads on his forehead and threw another sentence to Yang He.

"Yes, Your Majesty, I will go back and prepare for it, and then go to India." Yang He responded with yes, with the excitement on his face unconcealed.

For him, he had long been looking forward to the arrival of this day.

After bowing and bowing, Yang He turned around and left.

After he left the door, a little eunuch arrived at the door with an excited face and said something to Xiao Guizi.

Xiao Guizi then smiled and went into the imperial study room and said to Zhao Xu, "Emperor, the technical minister of the Science and Technology Department, Wang Chong has come and brought a telephone, saying that he wants to install it for the emperor."

"Oh?" Zhao Xu looked forward to it, "Then let him come in quickly, I will be impatient to wait."

Xiao Guizi understood and immediately asked the little eunuch to lead Wang Chong into the palace.

Soon, Wang Chong led three technicians over.

After saluting Zhao Xu, he presented the hand-cranked telephone in his arms to Zhao Xu. "Your Majesty, the Seventh Laboratory of the Research and Development Institute has lived up to expectations and has created the hand-crank telephone. Now Yancheng can immediately speak to the whole city."

Zhao Xu nodded and said to him, "Stop talking about the scene, work quickly and let me experience it."

When the war was in the south and west of Dasong, none of the other functional agencies were idle.

The cabinet is constantly promoting reform, and the Science and Technology Department has made an achievement of reform.

In the future, the scientific and technological development of Dasong will be coordinated by the Science and Technology Department.

The Science and Technology Department, led by Wang Chong, has also broken through many technologies and contributed to the power industry.

This mobile phone is one of the small achievements.

After all, the biggest problem with a mobile phone is power, and the technology of the phone itself is not difficult.

Simply put, there are two important structures for the structure of a mobile phone.

One is a rotating turntable and a telephone receiver.

The rotary dialing structure is actually a small generator.

Each dial is equivalent to sending electricity once. This current is like the current of a wired telegram, which will close the magnetic chip in the switchboard.

Because according to the number, the current intensity emitted by each shake is different, so the dialed number can be distinguished.

The switchboard then connects the corresponding telephone line to the dialed telephone line, and then you can make a call.

"I heard it all, the emperor said, work quickly." Seeing that Zhao Xu couldn't wait, Wang Chong laughed and immediately asked the technician to install a mobile phone.

When the mobile phone was developed, the telephone line laying in Yancheng had already begun.

As long as each organization installs a telephone, Zhao Xu can directly contact the cabinet, Defense Department and other institutions in the Imperial Study Room.

After receiving the order, the three technicians became busy.

The installation of the mobile phone is completed in just one cup of tea.

At this time, Wang Chong said, "Your Majesty, there are only two mobile phones, one in the R&D Institute, and the other is sent to the Emperor, so now you can only call the R&D Institute."

"Then call your R&D Institute." Zhao Xu said with a smile.

For him, this was a good start.

Telegrams have certainly caused the information transmission across Dasong to undergo a qualitative change.

However, after the phone appears, the efficiency of information transmission will be higher.

Next, as long as the manual telephone is mass-produced, Yancheng can have the entire telephone conversation, and then it will be between cities and provinces, and even between Dasong.

"The numbers are two zeros and one two." Wang Chong reported the number of the Research and Development Institute.

"Then my imperial study room should be two zeros, one one?" Zhao Xu looked at the ten numbers on the turntable.

"The emperor is wise, that's right." Wang Chong laughed twice.

"It's too few, I'll change it to eight digits when I go back."

This phone number is only three digits, meaning there are a total of one thousand phone numbers available.

If you change to eight digits, there are 100 million numbers to choose from.

Although he knew very well that Dasong might now popularize phone calls to the public.

But this expectation is necessary.

After saying this, Zhao Xu dialed zero twice, one two.

At this time, a woman's voice came from the phone.

"Do you want to transfer to the R&D institute now?" the woman asked, her voice trembling obviously.

Obviously she knew that the other end might be Zhao Xu.

"Yes, it's transferred to the R&D Institute." Zhao Xu replied.

"Okay." replied, and the woman's voice disappeared.

Then there was a "beep" sound of the phone.

Before it could sound twice, a voice came from the opposite side, "This is the seventh laboratory of the R&D institute, long live the emperor."

Zhao Xu was amused and laughed. During this experiment, all participants concluded that he must have called the first call.

I wanted to tease the other party, but Zhao Xu was afraid of scaring them, so he said, "Congratulations on your ability to overcome the hand-cranked phone technology. This call test is perfect. I am very satisfied. Thank you for your hard work."

"No...no hard work." The person on the other end of the phone stuttered and was also very nervous.

After asking about the next mass production of the mobile phone, Zhao Xu hung up the phone, looking satisfied.

Turning to Wang Chong, he said: "Next, we should promote the mass production of the telephone, and hand it over to the Communications Department directly."

The predecessor of the Communications Department was Dasong's Station System.

After handing over the telegram to the station system, the telephone will now be handed over to the Communications Department for management.

"Yes, Your Highness." Wang Chong replied yes.

Then he thought of something and said to Zhao Xu, "Your Majesty, in addition to the phone call, I have another thing to report to me. This is the matter of oil. This matter cannot be delayed. Before the internal combustion engine is developed, Dasong should establish the petrochemical industry in advance, otherwise the internal combustion gas without oil will be scrap copper and rotten iron."

"I understand what you mean." Zhao Xu said.

During this period, the R&D Institute only relied on a small amount of oil to conquer some smelting technologies in the petrochemical industry.

These small amounts of oil were transported by smuggling merchants from Middle Earth at risk of their lives to the vicinity of Tianshan Mountains and then transported them from Tianshan Mountains.

It can be said that the quantity is small, but the cost is very high.

The oil passing through this way can only be used in laboratories, but if it is smelted in large quantities, not only is the quantity a problem, but the cost issue will also reach the sky.

Therefore, next we must find a way to reduce costs for Dasong.

To this end, he had instructed Chen Shou of the Ship Department to design and build a merchant ship dedicated to transporting oil.

In this way, the transportation problem is solved.

But there is another issue in addition to transportation.

This problem must be done by Da Song himself to reshape the order in Middle Earth.

Now, Qinshan has flattened India.

Then, like Ebony City, Tianzhu became the springboard for Dasong to extend his sphere of influence into Middle Earth.

Next, he will use these two springboards to dismantle the Turkish Empire.
