Compared with the complete shock of Qin Qiong and the others, Li Shimin was ecstatic.

Your own orders can be transmitted thousands of miles away, and a cup of tea is enough, so it can be said to be infinitely useful for military command, civil administration, train traffic, and so on.

With the telegraph, then there will be electric lights, and then electric motors.

Datang's industrial age has begun.

Li Shimin was very calm about the telegraph, even if he knew the name of the telegraph, he would call the thunder machine according to the new name of Liu Mu.

The eldest grandson Wujian and Dugu Lanruo were very surprised, there was such an artifact.

The two girls were pleasantly surprised, and they even learned some knowledge about telegraphs.

Li Shimin and Liu Mu frowned.

"Where the hell is the difference?" Li Shimin is not asking the researchers here, nor is he asking Liu Mu, but he is just talking to himself.

Yanagi also doesn't understand that the principle is the principle, and the product is the product.

A mistake in any link may turn the product into waste, not to mention that the telegraph machine manufactured at present can really travel 500 miles away, but it will be scrapped after not many times, which is the reason why Li Shimin frowned.

And the cause of the damage is the same every time, the coil is damaged.

An official in charge of the institute is making a presentation.

"Sage, we have analyzed various reasons, and we are constantly improving the machines and solutions for building the wire, and I believe that the problem is in the copper wire. Present battery, power pedal, Tencel ......"

Liu Mu stood there and listened for half an hour, and suddenly said, "Wire drawing machine!" ”

"What?" Li Shimin didn't understand what Liu Mu was talking about.

Liu Mu also thought of it suddenly, and explained at the moment: "The copper wire used now is rolled out, and the copper wire looks the same thickness, but it must be unqualified in the subtleties, and the copper wire should be pulled out, not pressed out." ”

After listening to Liu Mu's explanation, Li Shimin immediately asked: "Who has heard that steel wires are pulled out." ”

Hundreds of excellent craftsmen stopped what they were doing, and an old steelmaker stepped forward to report after getting permission: "Sage, when making copper chariots and horses in the former Qin Dynasty, the copper wire was pulled out. Using a cooked copper rod to heat up and pull it out, this technique is not too difficult. ”

Liu Mu asked: "Is it possible to evenly pull out a copper wire that is thousands of feet long and fine and completely consistent?" ”

"Before, it was certainly not possible, but if there was a steam engine that could guarantee a stable speed, it would be possible."

Li Shimin immediately ordered: "Two, prepare two steam engines of the best quality for them, and prepare them immediately." ”

"Brother Huang!" Liu Mu still calls Li Shimin the imperial brother when there are outsiders: "This matter can't be rushed or rushed." Let them experiment slowly, which is already only half a step away from success. ”

Li Shimin nodded: "What else do you need me to provide you with doubly." ”

"The saint, the minister, and the others decided to start all the processes from scratch, and the reason for the damage was almost the same every time, it suddenly became very hot while it was in use, and then it was damaged. According to our accumulated knowledge of lightning, when a piece of copper wire passes through lightning, it heats up in a small place. ”

Li Shimin nodded: "I see your efforts, you have been working hard for a long time for this thunder machine. A journey of a thousand miles begins with a single step, you have completed the first stage, and this also sees the end of the second stage, I believe that you will be able to overcome many difficulties, and the thunder sound machine will benefit Datang. ”

"I'm going to wait......

From the director of the research area to the young apprentices, they all said that they would do their best to solve the problems at hand, and they would definitely live up to the grace of God.

Liu Mu persuaded on the side: "Brother Huang, it's been a few days since you left Chang'an, why don't you go back to Chang'an and wait for news?" ”

"Good!"

Li Shimin also understands that if he wants to live here and stare at it every day, these people are afraid that their efficiency will be reduced several times.

The time of the day is just stressful.

A few days later, Li Shimin and Liu Mu returned to Chang'an City.

"Second brother, I didn't go back to Chang'an because of the telegraph, not because of the airship, not because of the train. Instead, they want to establish the Tang Royal Academy of Sciences, and the people of Huayuan have hardly left Huayuan over the years, and they are really very hard to be busy day and night. I want to give them an honor. ”

"Yes." Li Shimin agreed without saying a word.

Liu Mu took out a book bound with thread that was worn out even the corners and placed it on Li Shimin's desk.

Li Shimin picked up the book with great curiosity.

When I opened it, I found that it was not a book at all, but a blank book bound up, and it was a plan written in it.

Li Shimin originally planned to laugh at Liu Mu for using such a shabby blank book, but when he looked at its contents, Li Shimin was deeply attracted and didn't care whether the outer skin of the book was damaged.

It's a plan.

The content of the plan is that Huayuan, as the top research institution of Datang, will definitely limit Datang's scientific and technological growth if all projects, large and small, are studied by Huayuan.

If you divide some of the content, it might work wonders.

Li Shimin flipped through a few pages and put Liu Mu's plan on the table: "You have been writing this for a long time, right?" ”

"Yes, for about a year and a half, I often open it and look through it, and then think about what is lacking before continuing to write. Datang can make the Mediterranean feel coerced at the moment, relying on Datang's scientific and technological strength beyond their hundreds of years, how to maintain excellent science and technology? ”

After listening to Liu Mu's words, Li Shimin said: "Take copper wire as an example, if Chang'an City posts an announcement to purchase extremely high-quality copper wire, it is estimated that there are already craftsmen in a certain place who have sent copper wire samples to Chang'an, and there must be very good." ”

"Second brother, the first driving force that really drives the power of science and technology is war. But Datang will have war, but there will be no enemy that makes Datang feel embarrassed or invincible, so the power of war is not enough to promote Datang's technology at the moment. ”

Li Shimin nodded and then signaled, "Go on." ”

"Then there is another way, which is silver."

"Silver?" Li Shimin's first thought was to give a lot of encouragement.

Liu Mu said: "Datang's looms have been improving, it can be said that wooden looms have reached the extreme, and more efficient looms made of pure steel have entered the rapid development. ”

Yanagi poured himself a cup of tea and continued: "Speaking of boats, I have always thought that our ships are already very good. In fact, the construction of ships is still progressing, and some private shipyards have surpassed official shipyards in some small technologies. ”

Li Shimin lightly high-fived: "Second brother understands, earning coins is also the driving force for the development of science and technology." ”
