Looking at Yu Qian's back as he walked out of the Wenhua Palace, Hang Min was touched and sighed: "Yu Shaobao is my great Ming humerus, but the years urge people to grow old, and heroes are difficult to defeat the sword of the years!"

It's a little sad.

In fact, the ministers of the court who have had the opportunity to see Yu Qian in recent days know in their hearts, especially the many officials of the Ministry of War, who have a sense of foreboding, and Yu Shaobao is probably about to run out of oil.

The twilight of the hero and the white-headed beauty are the most regrettable things in the world.

Yu Qian, the hero who led the Ming monarchs and ministers with his own strength, crawled out of the iron hooves of Yexian and climbed out of a desperate situation, is still old after all.

Many people still remember the scene when Yu Qian ordered the bombardment of Yexian Battalion.

How magnificent.

It was also that bombardment that made Ye Xian know that the Baobao Sect went south as a stepping stone, and repeated the method of the former Yuan Brilliant method, which would not work in the Ming Dynasty!

At that time, there was a fishing city in the Great Song Dynasty.

But after all, it couldn't stop the Mongolian iron horse from entering the main pass.

But when the civil fort changed, the Ming Dynasty had Yu Qian!

Zhu Jianji also has some feelings, even if he has been on the throne for five years, as the son of heaven of the Ming Dynasty, the respect of his status is above that of hundreds of civil and military officials, plus his civil and military martial arts, he has already surpassed Yu Qian's merits to the Ming Dynasty, so psychologically, Zhu Jianji can actually look down on Yu Shaobao.

But in Zhu Jianji's heart, Yu Shaobao is still the great wall of the Ming Dynasty.

Need to look up.

But I didn't expect that I would be able to look at the Great Wall of the Ming Dynasty in my life.

Zhu Jianji sighed deeply.

Hang Min said, "What does Your Majesty command?"

Just conquered the big city, and now there are a lot of things on the Indochina Peninsula, Your Majesty did not leave the Ministry of Officials, the Ministry of War, and the Governor's Office of the Five Armies, but he left his own Ministry of Works, and there should be more important things to explain.

Zhu Jianji said: "Regarding the establishment of the Political Envoy Department and the General Capital Department announced by the General Undertaking of the Indochina Peninsula, although I have many rules of moderation to implement together, but after all, the Tiangao Emperor is far away, if there are really people over there who disobey the court, they can indeed make trouble, this is an intolerable thing, and there is a problem, in the future, my Ming Dynasty will definitely continue to expand southward, westward, and northern expeditions, the army will be far away from the homeland, and the military orders of the court will be transmitted too slowly, so whether it is to strengthen the control of the place, or to deepen the connection between the imperial court and the expeditionary force, I'm going to get a communication device out of it."

Hang Min was puzzled and said, "Is there a faster way to transmit it than wolf smoke?"

The wolf smoke passed layer by layer, in fact, it was already very fast.

The wolf smoke transmits the signal, and the eight-hundred-mile expedited post man transmits the content, which is the traditional way of communication.

Zhu Jianji smiled: "Wolf smoke? It is too backward and cannot meet the needs of transmitting rich and clear information, so I want to build a communication device that can transmit complete and detailed information from the local area to Gyeonggi in real time!"

Hang Min was a little incredulous, "Instantly?"

Zhu Jianji said: "Yes, for example, if there is a turmoil in the Indochina Peninsula, and Nanjin Yiwei receives the news at noon, then he can use this communication device to put the spy report on the details of the turmoil on my table before two o'clock in the afternoon!"

Hang Min's face was incredulous, "Less than two moments, passing thousands of miles?"

Zhu Jianji asked, "Hang Shangshu, what do you think is the fastest thing in this world?"

Hang Min didn't think twice, "As long as our steam engine continues to improve its performance, sooner or later the steam transporter will become the fastest in the world."

Zhu Jianji shook his head, "That's not right."

He also said, "Didn't Hang Shangshu discover a phenomenon, even if you are far away from Gyeonggi, when night falls, when the lights on the streets and alleys of Gyeonggi are turned on at the same time, even if you are thousands of meters away, you can instantly see the glory of Gyeonggi, and the fastest in the world is light. But the electricity is also running very fast, and as soon as you see the electric switch closed, the lights on the streets and alleys of Gyeonggi are lit almost at the same time."

Hang Min was puzzled, "But this can't be used to transfer content."

He understands the reason.

It is like wolf smoke, which transmits electricity as a signal to Gyeonggi layer by layer.

Zhu Jianji

Shaking his head, "Hang Shangshu, you misunderstood."

Get up, walk to the side, pull the light switch, wait for one second and then pull it down, pull it back after one second, pull it back again after one second, and after three times, change it to three seconds and pull it again, and so on several times.

Hang Min is worthy of being a pioneer in this era second only to Zhu Jianji in terms of ideology and cognition.

Immediately understand in seconds.

Shocked, he said, "Your Majesty is saying that you will use the bright time of this lamp to agree on a code and make this code into a system to benchmark many words in the Xinhua dictionary?" The Indochina Peninsula transmits the long and short serial number of this lamp, and according to the serial number, the Gyeonggi side can find the corresponding text from the Xinhua dictionary and transcribe it to form a recital?"

Zhu Jianji was also a little shocked, Hang Min was so smart?

I just hinted at it, and he even came up with such a thing as a codebook, and sure enough, I am a great person in China's Shenzhou Diling, and I have never been poor in talent!

Laughing: "Hang Shangshu is only half right, the essence of signal transmission is to rely on electricity, but not simply to use the brightness of the electric light as the signal carrier, it needs a professional equipment, this equipment needs to use a special line, when the time comes, the two devices between Indochina Peninsula and Gyeonggi will be connected by a special line, and then the information will be transmitted through the on/off and length of electricity, so that you can directly cross thousands of mountains and rivers directly to Gyeonggi at one time."

There is no way, limited by the times and the theoretical knowledge of technology, Zhu Jianji can only build a cable telegraph first, and then slowly delve into the matter of wireless telegraphy.

Of course, this thing is difficult.

But the current territory of the Ming Dynasty is too large, and it will be even larger in the future, if you want to control the world, you must upgrade this communication technology now.

Otherwise, the overseas bases will have changed owners for a year and a half, and Gyeonggi will still be in the dark.

He added: "I plan to hand over this matter to the Royal Power Company, and at that time, I may have to build several large hydropower stations along the way from Gyeonggi to Indochina, and at the same time build a city that never sleeps, to ensure the power supply of this communication equipment line.

Hang Min was silent for a while, "It's feasible!"

Zhu Jianji said: "At that time, the city where the Indochina Peninsula General Undertaking and the General Envoy Department and the General Capital Department are located will also build a hydropower station, at least to ensure the electricity supply of our local government institutions in the Ming Dynasty."

Hang Min said: "The Ministry of Industry can contribute funds to cooperate with the Royal Power Company, but there is no one, at most, a group of officials can only be assigned to conduct research on the project, and the manpower and specific implementation of the construction of the hydropower station need to be operated by the Royal Power Company."

The Ministry of Industry is indeed too busy.

Because in the next few years, Daming will build several cement official roads, build railways, and build train production lines, which are all key projects that Your Majesty personally explained.
