The two of them almost trotted all the way to the university, Xian Ning was more impatient than Jiang Xingchen, she was busy with the generator set before, and she didn't see it with her own eyes.

As soon as he entered the laboratory, a group of researchers came up, and one of the young men waved a note and shouted: "Dean, we have succeeded, look!"

Xian Ning took the note, only to see that there were lines of different lengths drawn on it, and there were many dots.

"That's the encoding, and the signal received here is exactly the same as the transmitting side, without any loss. Several young men spoke in unison, their faces flushed with excitement. Who would have thought that the message would be delivered like this before they were engaged in this research, but such a miracle was born in their hands.

"What does this mean?" Although Jiang Xingchen knew that it was Morse code, he couldn't read it.

"The Star Collar is a place where miracles are made!" replied the young man at the front.

"Okay!" Jiang Xingchen nodded vigorously and asked, "What's your name?"

"Sir, my name is Li Chong!" replied immediately, and you could tell from the tone of his voice how excited he was. He was one of the thousand children, and not long after he joined the researcher, he didn't expect to be asked by the lord for his name. As far as he knew, all the people whose names were remembered by the lord were now prominent.

Xian Ning said on the side: "This kid has just joined the research team, and he is very energetic. I'll tell you he's the one who found the spark!"

"Do a good job!" Jiang Xingchen patted Li Chong's shoulder, and then beckoned to Xian Ning: "Let's go, let's go to the other side and send a telegram!"

The two went to another laboratory, and several researchers here all looked at Li Chong, unable to hide the envy in their hearts. At the same time, he secretly sighed that this kid was lucky. Zhi can be remembered by the lord, and at least he can lead a research team by himself like Zhou Lin. Funds are open to supply!

Li Chong showed the other side, and Jiang Xingchen immediately lowered his eyebrows after leaving. Although he was lucky to be asked by the lord for his name, but here are all his predecessors, and he is more solid than him in terms of experience and knowledge, and he does not have the strength to his tail.

On the other side, Jiang Xingchen and Xian Ning arrived at the laboratory where the report was issued, and immediately asked the researcher to send a sentence, which was similar to the previous sentence: "Xingchen Ling is the place where dreams set sail!"

Soon Jiang Xingchen heard a familiar ticking sound, the reason why it was familiar was because he had often seen it on TV in the previous life.

It didn't take two minutes. Li Chong ran in happily and said loudly: "Sir, I received it! Star Leader is the place where dreams set sail!"

Jiang Xingchen smiled and nodded, although he was calm on the surface, he secretly clenched his fists hard. The advent of the telegraph represented the beginning of communication, which would usher in a new era, in which even distant messages would arrive instantly, and the ancient methods of communication would be gradually replaced.

"You guys get ready, and we'll start building a telegraph office in the next two days! You have to be responsible for guiding!" Jiang Xingchen ordered to rush to the city hall. Let Mei'er arrange the telegraph office.

But as soon as he took two steps, Jiang Xingchen suddenly thought of a question, turned his head and asked, "By the way, what do you use for the electricity of the telegraph?"

"The battery invented by the lord!" Li Chong walked to the back of the telegraph in two steps. A piece of white cloth was removed from the table, revealing a cabinet that looked like a small shelf, and inside it were all wires with metal pieces inserted and connected together!

"Oh, I'll go!" Jiang Xingchen stumbled at his feet. I slapped my head hard, why did I forget the battery.

"Stars. What's wrong?" asked Xian Ning as she stretched out her hand to support him.

Jiang Xingchen did not speak. My mind was spinning. Although the telegraph has been studied, the battery has become a shortcoming, and in the future, there will be more and more nodes in the telegraph network, and it will not be possible to use potatoes all. The next step is to study wireless transmission, bring a mobile radio station, and have to carry 100 pounds of potatoes on your body, which is also too inconsistent.

The development of dry batteries, metal zinc, manganese dioxide, graphite is easy to do. What to do with the pasty electrolyte solution, he didn't know about other solutions, but he remembered that he had read the information and said it was ammonium chloride. Ammonia is required to produce ammonium chloride, and it can't be synthesized now.

If it is replaced by other acid and alkali salt solutions, whether it can become a paste, and whether there is a problem with mixing with manganese dioxide and carbon rods are not clear, and they need to be tested.

"Xingchen, Xingchen!" Xian Ning saw that Jiang Xingchen was stunned, and retreated from him twice.

"Ah!" Jiang Xingchen came back to his senses and said, "The power supply can't use potatoes all the time, and the hand-cranked generator is unstable. Need to study the battery...... Until the research comes out, use potatoes or wet batteries for the time being. Wet batteries are metal sheets and electrolyte solutions, and this Xianning should know ......"

After giving some general instructions, Jiang Xingchen asked Li Chong to temporarily take charge of the guidance of the telegraph office, and then turned around and left.

Walking on the way to the city hall, Jiang Xingchen sighed secretly, the industry has developed to a certain extent, and the chemical industry is a hurdle that cannot be bypassed. The synthesis of ammonia and the preparation of sulfuric acid from sulfur dioxide to sulfur trioxide are very difficult. Especially since this world has not found saltpeter, which makes him muttered a little in his heart.

Plants need nitrogen to grow, and you can't live without it. But thinking of the anti-heaven effect of the vitality, Jiang Xingchen couldn't be sure.

"Although there are still shortcomings, but anyway, the telegraph was invented, and if it is only used in a few nodes, it is the same with potato batteries, although it is a little bulky, but it is more environmentally friendly!"

In the end, Jiang Xingchen explained himself, after all, battery research is not a short-term thing. Grid laying, watch production, weddings, planning of metropolises...... There are still many things to do, and wireless telegraphy has not yet begun to be developed, the construction of railways has just begun, and there is no need to rush the research of batteries.

When he arrived at the city hall, Jiang Xingchen told Mei'er about the telegraph office and divided it into two parts. Part of it is under the jurisdiction of the town hall and is used for communications. The other was in the hands of the Ministry of Transport, since the demand for telegraphy was greatest along the railway lines.

Mei'er immediately called a meeting of the newly formed transportation department, and soon began to mobilize labor, and began to erect the first telegraph line between Xingchen Ling and Hongyuan City......

After Jiang Xingchen came out of the city hall, he did not go back to the lord's mansion, but went to the back mountain. The night before yesterday, I was thinking about feeding the demon beasts to gather vitality, but I happened to have an inspiration, so I delayed it for another two days.

When I came to the back mountain, I didn't need him to greet him, and there was a group around him after hula. Crabs, leeks, spirits, small pompoms, pink and pork ribs flying in the sky, all staring at their eyes and calling non-stop, listening to the sound is very aggrieved.

"Isn't it just that I haven't given it for a few days, look at your appearance, all of them are foodies!" Jiang Xingchen raised his foot and lifted the crab, this product was the most noisy, he screamed and didn't say anything, and stretched out his tongue to lick his hand, I don't know if it's disgusting.

"Look at other people's big white, there is no ...... like you" Before Jiang Xingchen's words fell, a hairy head appeared in front of him, and his big black eyes blinked at him.

"I'll make it, you're here to slap me in the face!" Jiang Xingchen was so angry that he kicked again, and you appeared as soon as I finished speaking.

Dabai still looks heartless, and he doesn't care about selling cuteness. The crab is not happy, boss, why are you kicking me!

At this time, there was a chaotic sound of horses' hooves, and a purple cloud seemed to float out from the direction of the old village, and in a moment a large group of nightmare beasts arrived in front of him.

The corners of Jiang Xingchen's mouth twitched, it was really a shame to get such a group of foodies. He originally said that he would feed it in two days, so he might as well take a break and slow down, these goods are good.

Especially the little white horse with golden horns, but he drilled into his arms, don't you know that the sharp horns pierce people.

"It's still good for tofu, you don't want to return for your work, it's like these foodies!" Jiang Xingchen sighed, and still fed these guys.

Although Jiang Xingchen has now gathered a large number of vitality, there is no pressure on one hundred or dozens of groups. But there were too many demon beasts, and a few high-level ones and one or two regiments were not enough, so in the end, he rested three times and fed for more than two hours before he could take care of them.

When the demon beasts all ran away, Jiang Xingchen, who was sweating profusely, was so tired that he couldn't stand up.

"Boy, are you done with your work, do you want to discuss something?" Jiang Xingchen was gasping for breath, and the old man suddenly appeared in front of him and looked at him with a smile.

"Oops!" Jiang Xingchen was startled, and said loudly: "You are an old immortal, don't you make a little noise, why are you really like a ghost!"

Complaining, Jiang Xingchen asked, "Aren't you already gone?" I haven't seen the old man for the past few days, Jiang Xingchen thought he had gone to the deep sea to catch crabs.

"Cut, I'm already back, okay!" said the old man, pouting.

"It's back, so fast! It would take three days for the night owl to fly anywhere...... You haven't been gone for six days!" Jiang Xingchen asked in surprise.

"Who told you I went to the deep ocean? I'm going to Hongyuan City, okay!"

"What are you doing in Hongyuan City?" Jiang Xingchen was even more strange, didn't this old guy go to the deep ocean to catch spider crabs.

"You come with me!" The old man grabbed Jiang Xingchen and dragged him away.

"Old thing, I haven't slowed down yet, where are you pulling me to?" Jiang Xingchen softened under his feet, staggered after the old man, and shouted in his mouth.

The old man was even more straightforward, picked up Jiang Xingchen and ran directly.

A moment later, the old man led him to the train station, where he stopped in front of a dozen large iron cages.

The cage is large, more than five meters long and wide, and the metal strips that make up the railing are the thickness of a thumb. Jiang Xingchen frowned and asked after seeing it, "Why are you letting me see these cages?"

"From the beginning, I wanted to go to the deep ocean to catch a few spider crabs. But then I thought about it, isn't there going to be a celebration in September, so I have to have some high-end food. So I wanted to get a batch back, and I had these cages made by me at the steel mill...... Well, I'm an old man, it's interesting. If nothing else, lend me the ribs and the night owl!" )

PS: During the rehearsal of the New Year's Day program, I still have to sing as a person with incomplete five notes, and the leaders are not afraid of hearing internal injuries. I was busy until half past ten before I started writing, and now I've just finished writing, I'm sorry!
