Chapter Forty-Six: Discovering the Spy and Opening the Phone

Zhang Zhimu knew that Yang Yulin said that she had agreed to think about it, but she was going to discuss it with her little sister.

I don't know what Yang Yulin, Song Jiaxin, and Yang Qinglian have been muttering for a long time, and finally Yang Yulin led Song Jiaxin to Zhang Zhimu, Yang Yulin said: "I talked to Jiaxin, and she also agreed to go to the command center." ”

Zhang Zhimu looked at Song Jiaxin and said: "Xiao Song, from the time you came to work with me to the present, I found that you have changed a lot, from a girl who didn't dare to speak, to now being generous, you have simply changed as a person." And that Yang Qinglian is also the same as you, I watched you change. Now I need to put a burden on you, but this position may be more tempering. ”

Song Jiaxin said: "It is my honor to be able to work beside Mr. Zhang, and it is my luck to be supported by Yulin. I must work hard in my new position, live up to the trust of Mr. Zhang and Sister Yulin, and will definitely not disgrace you. I will keep in mind that I am the one who came out of Mr. Zhang's side. ”

Song Jiaxin's words were very decent, and at first glance he was very tutored, Zhang Zhimu listened to it and was happy, and said: "Xiao Song, your job is very important, because it will involve a lot of secrets, I don't worry about others going, otherwise I won't transfer you out of Yulin." When you arrive at this post, you must not only be careful about technology, but also pay attention to confidentiality work. ”

Song Jiaxin said: "Mr. Zhang can rest assured that our work here is also confidential, and we know the importance of confidentiality. I will keep Mr. Zhang's words in mind. ”

Yang Yulin and Song Jiaxin went out, and when they were about to close the door, they heard Yang Yulin whisper to Song Jiaxin, "I didn't expect you to be so good at talking." ”

Zhang Zhimu knows that Song Jiaxin is not only beautiful, but also very smart, and knows when to say it and when not to say it. It's a buildable material.

Perhaps because they felt the atmosphere of war, Yangchang and they quickly got out of the switchboard, and Li Yunhe also helped get a few telephones. From the beginning of switch commissioning, Song Jiaxin followed to participate. With the help of Yang Yulin and Huang Yukun, Song Jiaxin was selected with ten young girls who were articulate and smart, and these eleven people formed a telephone class. Yangchang sent people to give them lectures and conduct training. From ordinary circuits to the principles of telephones, they were not only carefully explained, but also instructed to assemble telephones from telephone parts. That way, if there are some minor obstacles to the call, they can handle it themselves.

The telephone exchange room and the switchboard were given a total of two rooms, one was a computer room and the other was an office, which was in the command center and arranged next to the telegraph room.

After the switch was commissioned, the first place to install the telephone was, of course, Zhang Zhimu's office.

After setting up the phone, Zhang Zhimu picked up the phone and shook the phone with his hand, there was a phone answered by Song Jiaxin himself, and Xiao Song's familiar voice came from the phone, "Hello! Where do you want? "This is a greeting that has been trained for a long time.

Zhang Zhimu said: "Xiao Song, hello! Your voice is clear. Please pick me up Mr. Chen. ”

"Okay, wait a minute!"

Zhang Zhimu heard the ringing sound from the earphones, followed by a click, and Chen Yufeng's voice came from the phone: "Hey? Is it Chiki? ”

"It's me, Uncle Chen, your voice is very clear. How's my voice? ”

"Okay, your voice is clear too. It will be so convenient to have a phone in the future. Commanding a war again is like commanding in front of you. Chen Yufeng said excitedly.

Zhang Zhimu said: "We should form a new branch of the armed forces, which is called the Signal Corps. It should be done right away. In the future, on the battlefield, we must also have the ability to quickly arrange communication lines. ”

Chen Yufeng said: "I will immediately ask Qin Peng to organize people to arrange this matter." There is one more thing, Mr. Ouyang is about to tell you. ”

Over there, Chen Yufeng handed over the telephone to Ouyang He, and after a while, Ouyang He's voice came, "Mr. Zhang, it's too convenient to have a phone this time, so you don't have to run around without having something to do." There's one thing I want to discuss with you. The soldiers from Tongguan, Liu Yun, and they have all been selected. Together with the wounded soldiers, they took more than 2,800 people. The question is what to do with the officers who came from Tongguan? ”

Zhang Zhimu said: "I have thought about this matter, the older ones should arrange other jobs, and the younger ones will be arranged to be staff officers in the staff department first, and then arranged when there is a chance, and we can take care of it when we are awarded." We also have to observe and use them again to see how they are, and those who should be trained should also be trained, and I think that a large number of officers and soldiers will soon come over. We have to come up with a way, not all of them are arranged by us, and we have no obligation to arrange the defeated army for the emperor. ”

Ouyang He said: "I understand, we will immediately set up a team to do this." It just so happens that people in Tongguan can also arrange it. But I think it's great to get the phone to all the front-line command posts as soon as possible. ”

The phone was secured, and Yang Yulin asked Yang Chang to install an extension in their outhouse. Zhang Zhimu also felt that it was better to let them answer the phone first.

The first person to call Zhang Zhimu was Li Zhi. After the phone rang for a while, Yang Yulin answered the phone, not very used to talking on the phone, Yang Yulin almost shouted at the telephone: "Alas! Who are you? ”

Zhang Zhimu hurriedly went out and said, "If you are quiet, people can hear it." ”

Yang Yulin said embarrassedly: "You take it, it's Li Zhi." ”

Zhang Zhimu picked up the phone and said, "Hello, Li Zhi." ”

Li Zhi on the other side of the microphone said: "Mr. Zhang, I also installed a phone here." Do you have time now? I have something I want to tell you in person. ”

"Yes, come here." Zhang Zhimu put down the phone, came to the outhouse, and said to Yang Yulin: "In the future, when you pick up the phone, you should make a quieter voice, because if the voice is loud, you may hear it more clearly." Also, pick up the phone in civilized language. Start by saying, 'Hey! Hello! I want to know who the other person is saying, 'That's the one?' Where? ’”

Yang Yulin said: "How do I feel that you seem familiar with making phone calls? You know everything! ”

After Song Jiaxin left, Yang Yulin brought three more girls, all of whom were more beautiful than the other, and they were all carefully selected by Yang Yulin. When they heard Yang Yulin's words, they all lowered their heads and laughed secretly, but they didn't dare to make a sound.

Zhang Zhimu was speechless, in his previous life, there were too few days when he didn't call. It's a very new thing here. I don't know what kind of reaction the Ming Dynasty will have when the "Yaogang Weekly" reports this matter.

Li Zhi came, and the first thing he said made Zhang Zhimu deny it. He wanted to send someone into Song Jiaxin's switchboard class.

Zhang Zhimu said: "Don't even think about such a thing in the future." I'll let you know if you need to. ”

The second thing Li Zhi said made Zhang Zhimu's heart a little heavy.

Li Zhi said: "The person who sent Li Zicheng the "Yaogang Weekly" has been found. The people who pick up and drop off the newspapers are the drivers who deliver goods to the kiln every day. However, the delivery driver has not yet been found, and there are hundreds or even thousands of horse-drawn carriages in and out of our kiln every day. ”

Zhang Zhimu said: "Did you catch it? Won't you startle the snake? ”

Li Zhi said: "This person is a literati we got from the smelter, and this person works in a newspaper printing factory. Li Zicheng's men seized his family and threatened him that he had to give them a copy of all the printed materials. Otherwise, he will kill his family. We kept an eye on him for a long time, but we found that he might have noticed it, and we couldn't do anything about it. This man was very cooperative after being caught, and he said everything. We didn't embarrass him and continued to let him go back to work. Tell him that as long as he can help us catch Li Zicheng, the previous things will be written off. However, he also confessed that according to his feelings, Li Zicheng's people would have infiltrated a complete organization in our kiln gang, otherwise they would not have found a person like him and knew so much about his family. And the first time they talked to him, several people robbed him on the road. ”

Zhang Zhimu said: "It seems that Li Zicheng's intelligence work is doing a good job. ”

"What I'm most worried about is that they're going to do something to you," Li said. ”

Zhang Zhimu said: "Yes, I don't think it will be okay now, they will suddenly attack when Li Zicheng's army attacks, and the effect will be better at that time." ”

Li Zhi nodded and said, "Yes, but now we can't be unguarded." After the New Year, the city gate of our kiln will be closed at night. This can be safer, Li Jing's special forces still can't be withdrawn. ”

Zhang Zhimu said: "Fangcheng is undergoing internal renovation, and I see that the city gate will be closed at night. In this way, the safety of the entire kiln command organ can also be guaranteed. However, the safest thing is for you to find them all. ”

"We will do our best, but it will be difficult to clean it up in a short period of time," Li Zhi said. We still need to be more vigilant. ”

This incident made Zhang Zhimu's heart a little heavy, the most terrible enemy is the enemy who hides by your side and doesn't know who it is.

After Li Zhi left, Zhang Zhimu asked Yang Yulin to call Li Yunhe.

After Li Yunhe came, Zhang Zhimu said: "Yunhe, give you an urgent task, you have to get me twenty pistols as soon as possible, each gun should be equipped with two **." ”

Li Yunhe said: "Twenty is no problem, I can give it to you now, but tomorrow, I will match the holster and belt for you." ”

Zhang Zhimu followed Li Yunhe out of the office and came to Chen Yufeng's command center.

Ouyang He felt very serious after listening to Zhang Zhimu's words about the kiln gang being infiltrated by Li Zicheng, "Mr. Zhang, this matter can't be careless, we should let Li Zhi and them concentrate on solving this problem, otherwise we will have ** annoyance." ”

Zhang Zhimu said: "There are so many people in our kiln at once, and Li Zicheng's people are also easy to infiltrate, and Li Zhi has also sent a lot of people to mix in among them, but they are resolutely inactive, and no one can do anything." My idea is that the security work of our kiln leaders should be strengthened, and during this time, our kiln gang Fangcheng will close the city gate at night. There are special circumstances that allow for supervised entry and exit through a small door. In addition, I have asked Li Yunhe to get some pistols, and the main leaders of our kiln gang must be equipped with pistols in case of accidents. Tomorrow afternoon we will all go to the shooting range together to practice our guns. ”

The people in the kiln are busy, some are preparing for the war, and some are busy for the New Year.

There are a lot of fish that are constantly being pulled back from Xishan Bubbles and piled up on the playground of the primary school, which is used by trawling nets this year to prepare for the Chinese New Year and Huang Yukun They are waiting to process fish oil. Zhang Zhimu took a look with everyone and felt that he didn't seem to be in a hurry this time. When I got back to the office, I took out a pen and paper and began to draw and design the tube. Zhang Zhimu thought about it for a while, and felt that it was better to build a few electronic diodes first and practice his hands.

This electronic diode only needs four pins, two are filaments, one is the anode and one is the cathode. In fact, the electron tube is not complicated in principle, but the processing process is complex. The cathode of a diode is a small strip of metal that is wrapped around it to heat it. An anode plate is a metal plate that is enclosed on the outside. Such a mechanism needs to be encapsulated inside a glass case, with four pins exposed.

After drawing the picture, Zhang Zhimu asked Yang Yulin to send someone to invite Yang Chang over, and instructed him to tell him about the electron tube.

As soon as Yang Chang heard that it was about the electron tube, all five of them came over at once.

After the five of them sat down, Zhang Zhimu showed them the drawings he had drawn and said, "The drawings I drew are electronic diodes, and his characteristics are unidirectional conduction. We can use it to convert alternating current into direct current, and later we will use it for radio communication. Let me start by telling you the basics. ”

Zhang Zhimu got up on the blackboard and drew a schematic diagram of the electron diode. Yangchang and a few of them were also afraid of missing a little, so they drew it in their notebooks.

Zhang Zhimu said: "We have all studied chemistry courses, and we all know that there are electrons in metals, and it is possible to pull out electrons in cold metals under the action of high voltages, and we have all seen the arc." However, under the action of not too high voltages, we can also pull electrons out of hot metal.

Now we seal two pieces of metal in a vacuum glass tube, one heated and the other unheated, then we can easily pull the electrons in the hot metal towards the cold metal, but it is difficult to pull the electrons in the cold metal towards the hot metal. This gives the tube a unidirectional conductive characteristic, where electrons fly from hot metal to cold metal, which is physically defined as the flow of current from cold metal to hot metal. The reason for using vacuum is to avoid the air molecules from adversely affecting the movement of electrons.

The above is the principle of the electron diode, which is characterized by unidirectional conduction, with the hot metal as the cathode and the cold metal as the anode. The cathode metal sheet is heated with a filament next to it, while the anode is an ordinary metal sheet.

The voltage of this filament, we generally use a voltage of 6.3 volts, which should be able to heat the cathode metal to about 800 degrees. The thickness of the tungsten wire of the resistor is up to you to experiment. We should use 300 volts for the anode voltage of the tube, because the alternating current we will use for rectification in the future is 220 volts. ”

Yang Chang asked: "Mr. Zhang, didn't you say that we want to build an electron tube that can have an amplification function?" ”

Zhang Zhimu said: "You're talking about triode, that's what we're going to do next." Let's get acquainted with the manufacturing process of electron tubes. In fact, the triode is also very simple, just add a gate between the anode and the cathode to control the amount of current. You'd better get this electron diode right. This diode is successful and can be used stably, and it is easy to make a triode. ”

After Yangchang and the others left, Zhang Zhimu drew the picture of the triode again.

Zhang Zhimu originally wanted to draw a simple single-tube amplification circuit. Because in the previous life, the tube was rarely used, and if it weren't for the experience of being an enthusiast for a while, it would have been a lot of work to rebuild the tube circuit.

Without waiting for Zhang Zhimu to figure out how to draw, Yang Yulin came in and said, "Brother Zhang, go home." If you don't get off work, no one else can leave. You go back first, I'll go to my side to see those people in Zhangjiakou, and I'll go back immediately. ”

After Yang Yulin moved over, she still couldn't let go of those people in Zhangjiakou. Now that the school is on vacation, those who don't want to live in the school go back to Yang Yulin's original house, so Yang Yulin has gotten off work, and she has to go to see them first before going home.

Here, because Huang Yukun and Yang Yulin are very busy, Huang Yukun's cousin has been here to help and has not returned. Although sometimes my cousin is nagging, she is very capable, and Huang Yukun doesn't have to worry about the housework of the children at home. My cousin's two children earn a lot of money, and my cousin is also very happy, and Huang Yukun is not a stingy person, so he didn't give her less money. Now her relationship with Yang Yulin is also passable, and Yang Yulin will bring her something wherever she comes back, and the relationship will be much better.

Entering the house, Zhang Zhimu saw Huang Yukun playing with Erhu, and he went over to play. The children were amused, and the adults were happy.

Zhang Zhimu said: "I just told Uncle Chen that tomorrow afternoon, these leaders of our kiln gang will go to the shooting range to shoot targets. In the future, we will all be issued pistols. ”

Huang Yukun said: "I don't want that thing, you can all give pistols to female soldiers." ”

Zhang Zhimu said very seriously: "No, I have to go tomorrow." ”

"Brother, what's wrong?" Huang Yukun asked sensitively.

Zhang Zhimu said: "Li Zicheng's people may have infiltrated our kiln, and now there is no way to determine who they are." But the threat is all around us, and we all need to be safe. Everyone has to be able to defend themselves, especially our family. ”

Huang Yukun said, "Okay, I'll go tomorrow." Listening to Yulin, there is nothing difficult about shooting. ”

The next day, Li Yunhe's shooting range was very lively, and the brains of the kiln gang came, and Li Yunhe's people taught everyone shooting and gun maintenance one by one. When these people arrived at the shooting range, they could be considered resting, and they went to shoot a few shots happily. If you're fine, just sit next to you and drink soda of all flavors. This soda was prepared by Zhang Zhimu at the suggestion of the furnace foreman. But it soon spread in the kiln. With the support of Lu Chengxiang, a soda factory specializing in the production of soda and sorbet was established. This time, Lu Chengxiang asked the soda factory to bring the newly made soda and sorbet.

Yang Yulin and Lu Chengxiang joked: "Mr. Lu may not be so generous when it is hot, knowing that we can't eat much on a cold day, so we bring so many things." ”

Chen Yufeng also joined in the fun and said: "After eating the ice cream, I trembled, how do you say we can shoot?" ”

Lu Chengxiangle's round face lit up and said, "Look at it, I am kind enough to treat it as a donkey's liver and lungs this time." ”

Huang Yukun and Sister-in-law Xu didn't dare to shoot at first, but after Yang Yulin personally taught them to shoot a few shots, they were not afraid. They are all hard-working people, and they are not so squeamish.

This time, Li Yunhe also brought a few rifles to let the leaders get over the gun addiction.

After Yan Boju finished shooting the rifle, he said: "We will produce a little more of this rifle, and what kind of army do we need, each kiln gang person will be issued one, and it will be enough for each person to practice for two days." Li Zicheng is not enough to fight no matter how many people come. I don't need a pistol, I'll just bring a rifle with me when I go back. Ten or eight is not enough for me to fight. ”

Chen Yufeng said: "Old things are beautiful. A man with a rifle is not qualified to hold a rifle if he does not kill one hundred and eighty people. ”

Yan Boju was joking, but Yang Yulin was not joking. When she left, she actually took a rifle with her.

Seeing everyone practicing guns, Zhang Zhimu said to Li Yunhe: "This kind of pistol is only a pistol used on the battlefield, and it is powerful enough. But as a leader to defend himself, it is still too big. For self-defense, use a 7.65 caliber, and the gun is as big as a palm. ** Capacity doesn't need to be so much either. The main thing is to be lightweight, and it is convenient to hide wherever you carry out secret missions. When this battle is over, you will definitely come up with this kind of small robbery. Remember to be nice and pick it up. ”

Li Yunhe nodded and said, "I know." But I really can't care about it now, I'm going all out to produce rifles. Now there is no problem with guaranteeing 1,000 per month, and I try to catch up as much as I can. Strive to double production. ”

After everyone tried to rob it, they gave each person a pistol, and the pistols were all numbered. Zhang Zhimu said: "Everyone should protect their own matches, and report if there is loss or damage. So as not to have other problems. ”

On the way back to Yaogang, Zhang Zhimu sat in a car with Chen Yufeng and Ouyang He. In the car, Ouyang He said: "I went to Xishan Baozi in the morning, and I rushed directly to the shooting range from there. This time, they were given uniform outfits, and they looked different all of a sudden. I suddenly had an idea, those older soldiers in Tongguan Ningde have all been on the battlefield, and I think they are all sent to these reserve soldiers as officers at all levels, and their battlefield experience is exactly what these reservists lack. ”

Chen Yufeng said: "Good idea, but we need to train the people in Tongguan intensively, and those who don't know how to use muskets will teach them to use muskets." and teach them the rules of our kiln and how to lead the troops. We used to lead troops differently than they did. It's just that they are not allowed to beat and scold the soldiers, and this is not easy for them to accept. ”

Zhang Zhimu said: "We use those who can abide by our rules, and forget those who can't." ”

The people of Yaogang were in the panic of the whole Shanxi, and had a lively New Year.

But at this time, all the inns in Yaogang were filled in advance, which made Yang Jing very annoyed.
