  Chapter 828 Ji Shuyan

Zhao Hanzhang just sighed casually, but Fu Tinghan lowered his eyes to think, and then said: "It is not difficult to generate electricity, not to mention that we now have hydraulic facilities, we can also find coal mines, and even use human power to generate electricity. Telegrams are transmitted using short waves. Now The ionosphere is very clean, even though there are many dense forests and water networks, I believe that radio waves can be transmitted."

   "The technical difficulty lies in the electronic tube. I can't make it in a short time. I can only say try my best. You see, you need to wait for a long time."

  Zhao Hanzhang saw that he was seriously analyzing the feasibility, opened his mouth wide, and found his own voice after a while, "Then...then you have a try."

  Zhao Hanzhang began to think hard about the physics knowledge he had learned in junior high school and high school, and finally dug out a little from the depths of his memory, "What about the battery?"

Fu Tinghan smiled and said: "This is not so difficult. If we can make electronic tubes, then we can definitely make qualified zinc and copper sheets. The simplest batteries are aluminum, zinc, tin, iron, copper, silver and Gold, any combination of these two can transmit current. Zinc and copper have a better transmission effect. You can use both of them. It can still be used like in the century."

"In the future, when technology comes up, we can also use carbon rods and zinc to make dry batteries, or use lead dioxide to make reversible batteries." Fu Tinghan became more and more excited as he talked, "I still prefer reversible batteries, and dry batteries are no longer usable. , the reversible battery can be recharged and used repeatedly.”

  As a mathematics professor, how could he only study mathematics?

  His knowledge of physics is comparable to that of his colleagues in the physics group. Science subjects are interoperable, especially mathematics and physics.

  Fu Tinghan became excited, even more attentive than Zhao Hanzhang, and directly dragged her to look at the map.

  This is not a theoretical difficulty. He knows all the theoretical principles. This is a technical difficulty and needs to be pushed back.

  Before, whether Fu Tinghan was making glass, making iron and steel, water mills, or hydraulic forging presses, he was just doing his duty, not very excited, nor did he find it challenging.

  Because the technology used in it can be done by skilled craftsmen today, he did it just by combining their technologies or making slight improvements.

  What they lack is not technology, but ideas. He didn't say that after decades or hundreds of years, some people will think of taking this small step forward.

   But electricity is different.

   There is no electricity in this world.

  They really need to be created from scratch, and the technology applied in it, no one can make it except him.

  When he was studying, no matter the batteries, electrode tubes, or wires he applied were ready-made, now he needs to go back and make them bit by bit.

  If in the past he was standing on the front road to guide them and teach them to choose the right way to go; then now he is trying to open a way for those behind him among the thorns and wilderness.

  This sense of accomplishment is no less than doing math problems, which makes him very happy.

He pulled Zhao Hanzhang to the map to look at it, "This mountain forest is very large, so it is difficult to transmit directly between these two points. Fortunately, this side is mostly cultivated land. As long as it is not rainy, it should be reflected from this side. , but it will take longer..."

  But compared to the current transmission speed of information, the time for the tortuous transmission of radio waves is not worth mentioning at all.

  During World War I, wireless telegraphy was used on the battlefield. At that time, it could be transmitted for thousands of kilometers, and Fu Tinghan felt that it must be possible now.

   But to do this, he must first form a team.

  Before Zhao Hanzhang came back to his senses, Fu Tinghan had entered the next stage, turned his head and asked, "Give me Wei Jie."

  Zhao Hanzhang regained consciousness, "Who?"

  Fu Tinghan: "Wei Jie, and Ji Shuyan, I think they can be my deputy."

   Fu Tinghan has contacts with people who have taken refuge in Zhao Hanzhang. These two people are more interested in material movement and have certain research and talent.

  Zhao Hanzhang blinked, "Wei Jie is now in Luoyang, but Ji Shuyan, I remember he is in the army?"

  Ji Shuyan, a native of Wu Xing, had followed Tianmen Gengzhou, Yingchuan Yuyi and others to persuade her not to fight Gou Xi and throw herself into the trap, ahem, it was effective.

   Anyway, after that, Ji Shuyan stayed in Luoyang and studied with Zhao Cheng.

  The news of the Huns' invasion of the south spread to Luoyang, and he immediately stepped on his long sword and left Taixue to go straight to Bei Gongchun, but Bei Gongchun politely rejected him after trying his kung fu and riding.

   Ji Shuyan was sad and angry and wanted to go to Yuzhou to find Zhao Hanzhang. When he left, he ran into Fu Tinghan who came to Beigongchun to discuss the war.

  He doesn't dislike Ji Shuyan's poor riding skills. No matter how bad his kung fu is, he won't be as bad as Fu Tinghan.

   Like him, he can’t mount a horse and charge into battle, but he can be a military adviser behind him. If the strategy is good and the general executes it well, isn’t that also victory?

  Although in the end Fu Tinghan found that Ji Shuyan was not very good at strategy, but his IQ was still very high, so he stayed in the army for logistics.

  When Fu Tinghan called him, he was calculating how long the newly collected grain and grass would be enough for them to last.

  As soon as he heard that Fu Tinghan called him, he took the list, thinking that he was asking about food and grass.

   As a result, his guards came and asked him to take him directly to the main tent.

  Ji Shuyan's eyes lit up, and he immediately put the list away and stuffed it in his arms, and sped up the speed.

   Fu Shangshu finally saw his military talent, and recommended him to the governor Zhao to lead the army to the battlefield?

  Ji Shuyan went to the door of the main tent and straightened his clothes before begging to see him.

  Fu An came out to invite him, "Please come inside, Mr. Ji."

  Ji Shuyan went in, and saw Fu Tinghan and Zhao Hanzhang sitting and standing, writing and discussing something before the case.

  Seeing Zhao Hanzhang, Ji Shuyan immediately stepped forward to salute excitedly, and wanted to state his views on this war and the strategy he had thought up recently...

   "Let's talk about it." Zhao Hanzhang waved his hand away from his ceremony, straightened up, turned around and sat down in front of the desk on the other side, picked up the official document and began to approve.

  Ji Shuyan was stuck in his mouth when he was full of words. He looked at Zhao Hanzhang, and then turned to look at Fu Tinghan.

  Fu Tinghan waved at him and asked Fu An to add another high stool so that they could talk while calculating.

  Ji Shuyan stepped forward silently, glanced at something on the paper that he couldn't understand at all, and asked, "What is this?"

Fu Tinghan said: "The speed of information dissemination is slow now, and it consumes a lot of manpower and material resources, so it is not safe. And when the enemy is in the middle, the information between allies and troops is not only slow to transmit, but also in danger of being intercepted and leaked, so I want to study the communication station."

  Ji Shuyan: "Fu Shangshu is right, but what is a communication station?"

  He understood everything before, but he didn't understand the last four words.
