"Can't even buy a hundred?"

Zhu Yuanzhang asked again, his expression nervous: "Is it too expensive?" ”

Li Shimin also saw it, and he also wanted this telegraph.

Surprisingly, not only Li Qingzhao, but even Lin Daiyu also looked at him expectantly.

When Chu Zhen saw Sister Lin's expression, she thought that her father was still an official outside, and her mother Jia Min should have also left the capital, and if she had a telegraph, she would be able to talk to her parents.

"It's not about the money."

Chu Zhen took out his mobile phone and asked him while searching for information: "How long have you been in Daming?" What happened to the war in Yunnan? ”

Li Shimin and Lin Daiyu still didn't know about the war in Yunnan in the Ming Dynasty, and Zhu Yuanzhang saw Chu Zhen burying his head in looking for a telegraph machine, so he simply started from the beginning.

"Five months ago, the fourth child, that is, my son Zhu Di, led the army to Yunnan...... Two months ago, with the help of Chu Zhen, they leveled the king of Liang.

Soon after, the fourth old man pulled the new cannon to the Longwei Pass guarded by the Duan clan in Dali, and after three days of encirclement, Duan Shi went out of the city and surrendered. ”

Zhu Yuanzhang was very satisfied with this battle, and said with a smile: "Duan Shi has surrendered, and the rest of the Tusi will either surrender or rebel, there is no need to worry, I am ready to let the fourth and Fu Youde come back in the spring of next year, leave Mu Ying and the 200,000 army behind, build a Tun army stockade, and march to the Tun and Mintun strategies to settle Yunnan." ”

Lin Daiyu was only responsible for listening, but Li Qingzhao was envious and complimented Zhu Yuanzhang: "Emperor Hongwu opened up the territory and set the peace of the world, which makes people admire." ”

Zhu Yuanzhang laughed.

Li Qingzhao sighed again: "It's a pity that I'm a Song official...... Fighting Xixia has been fought for a long time but has not been able to fight. ”

Zhu Yuanzhang stopped laughing and commented briefly: "The Song army can't fight, because the Song Dynasty is all about guarding the inside and outside, and using literature to control the military. ”

Li Qingzhao had nothing to say, because if he talked too much, he would inevitably mention Chen Qiao again.

Li Shimin said: "Nanzhao is located in a remote area, and it is not easy to govern, and the policy of Tuntian is also a last resort. ”

"That's exactly what I mean."

Zhu Yuanzhang agreed with him.

The two chatted with each other for a while about how to stabilize the frontier, and they all thought of the telegraph!

Li Shimin looked at Chu Zhen, "If there is a thousand miles of transmission, the Tang Dynasty can include the Western Turks, and the frontier extends to Tianzhu!" ”

Li Qingzhao and the three of them all laughed, and the current King of Qin didn't know how much land the Tang Dynasty would be able to lay in the future.

Chu Zhen, who checked the information, also smiled: "Tianzhu is in the south of Tubo. ”

"Where is Tibet?"

Li Shimin looked at the map of China.

"Tubo is the Western Qiang tribe," Li Qingzhao explained to him, "between Tuyuhun and Nanzhao...... It's a big piece of land. ”

She also looked at the map of Huaxia, which was now all included in Huaxia.

Lin Daiyu looked at Xiaoliuqiu Island, and couldn't help but say: "Father and uncle will use troops on the island next year, Amitabha, Buddha bless everything well." ”

Li Qingzhao took her hand and laughed, "My sister should ask the Chu Immortal for blessing, where do I need to recite Amitabha?" ”

Lin Daiyu looked at Chu Zhen, her face flushed, and she glared at her sister in shame.

Zhu Yuanzhang didn't look at the two girls playing, his eyes were on the map, and he fell to the place of Beiyuan, and said slowly:

"One day, the Ming Dynasty will take back all the land of the old yuan!"

Yuan lost its deer, and it was clearly orthodox.

Chu Zhen, who looked down to check the information, said: "You better revise the Yuan history first, the Yuan history is the worst batch of many history books." ”

"Yuan Shi is the worst? Not Jin History? ”

Zhu Yuanzhang glanced at Li Shimin, smiled, and said: "When we finish fighting Liaodong, we have captured Emperor Tianyuan, and arrested the ministers of Yuan Zhaozong, Taishi Harazhang, and Zuo Prime Minister Nahachu to Ying Tianfu, ask them personally, and then repair the history of Yuan!" ”

Everyone was eye-catching.

Chu Zhen put down his phone and said with a smile: "This way of cultivating history is a must!" ”

"Where's my telegraph?"

Zhu Yuanzhang took the opportunity to ask again.

Everyone looked over, and Chu Zhen took a sip of tea before saying, "The telegraph is gone." ”

"This ......"

"But there are amateur radio stations!"

Chu Zhen looked at Sister Lin and said with a smile: "It's more convenient than a telegraph, and it can also transmit sound for thousands of miles." ”

Lin Daiyu and Li Qingzhao glared at him one after another, this person loves to play tricks on them!

"Good!"

Zhu Yuanzhang patted the armrest of the sofa and said excitedly: "Let's ask for this Ye Yu radio, how much is a silver?" ”

Li Shimin was silently calculating what to give to Mr. Chu.

"Amateur is relatively professional, and can be directly called a radio station."

Chu Zhen first roughly explained the meaning, and then said: "I thought that personal wireless equipment was not easy to buy, but I checked it just now, and you can buy it at will, but individuals can't transmit signals casually, and you need to take the radio operation certificate and apply for a personal radio station." ”

“…… Do we need to take exams too? ”

Zhu Yuanzhang estimated that he would definitely not be able to pass the test.

"No, you don't."

Chu Zhen laughed, thought for a while, and explained to them like this: "In ancient times, there was a beacon fire to transmit messages, but once the enemy also set up a beacon tower, it would lead to chaos. It's the same with radio waves, which can cause chaos once thousands of people use them. ”

Theoretically, personal use of walkie-talkies with a power greater than 0.5 should be verified.

In fact, as long as it does not affect others, plus it is not a high-power signal transmitter, it is rarely checked.

Of course, if you want to use an amateur radio station for a long time, you must go to the certification.

Chu Zhen is not used in modern times, so he doesn't have to take the test.

"Why can a mobile phone be used by many people at the same time?"

Lin Daiyu took out the mobile phone that Chu Zhen gave her before, and since she gave it to her, she has been with her.

Because she noticed that Brother Chu's mobile phone was also inseparable from him.

"The signal of the mobile phone is aggregated to the base station and managed by the base station." Chu Zhen smiled and said, "In your place, there are only these radio stations I sent you, so you don't need to think about interference for the time being." ”

"For the time being?"

Li Shimin was a little surprised: "Can we make it soon?" ”

"Maybe."

Chu Zhen smiled, "I can't always give you radio stations, I still have to rely on you or your descendants to make them in the future." ”

Li Qingzhao subconsciously looked at Lin Daiyu, the children and grandchildren of the two of them......

"Give me twenty years!"

Zhu Yuanzhang said, "As for the crown prince Zhu Biao, I don't care too much about him, let him make the telegraph." ”

Chu Zhen nodded and said, "Since it started from the telegraph, you will use less voice calls on the radio station, and usually use coded communication." ”

"Encoded communications?"

"For example, if I clap my hands to represent a point, my palms together represent a bar, and I can represent different meanings. In the early days, the telegraph transmitted such simple information, which was then interpreted into handwriting. ”

Chu Zhen didn't need to say it in too much detail, they could understand it if he explained it a little.

"I'll buy some at each of the stores first."

Chu Zhen smiled: "After I buy it back, I will study how to use it." ”

"Thank you, Mr. Chu!"

Li Shimin thanked him with a smile, and Zhu Yuanzhang said: "Let's level Liaodong and then repair the history of the Yuan Dynasty, have you sold those jades?" ”

Li Shimin also looked at it, and he found that the painting of Wang Youjun was hung on the wall.

Li Qingzhao was also happy, but she thought that even if she bought it back, she was afraid that she would not be able to help Da Song, and her parents were also at home, so they could not use this radio station for the time being.

"The money is still enough, rest assured."

Chu Zhen looked at Li Shimin, "After I left, what happened in Chang'an City?" ”

All three looked over.

Li Shimin first said that his father asked him to go to Luoyang to build the banner of the Son of Heaven, but it was shelved, and then said simply: "My father saw that many officials and people were willing to go to Luoyang with me, and he seemed to be a little displeased, so he removed me from the post of Daxingtai in Eastern Shaanxi Province and replaced it with the King of Qi. ”

Shaanxi East Province includes Luoyang.

Now that the king of Qi is in charge, it is tantamount to ending Li Shimin's idea of going to Luoyang.

"The officials and the people are willing to go to Luoyang with you," Zhu Yuanzhang asked him, "What kind of wish?" ”

"It's about running to tell each other and invite you to go."

Chu Zhen smiled and described the scene he saw that day, there were rumors everywhere in Chang'an City that the King of Qin was going to Luoyang, and many people said that the King of Qin was going to separate from the crown prince and take away half of the residents of Chang'an City.

As a result, many people in Chang'an City rushed to "sign up" to settle in Luoyang and discuss where there was arable land around Luoyang.

Zhu Yuanzhang looked at Li Shimin for a long time before he said, "If I were Li Yuan, you wouldn't even be the king of Qin." ”

Li Shimin knew what he was talking about, and replied: "If Emperor Hongwu is in Chang'an, I will only be in Luoyang." ”

"Hahaha!"

Zhu Yuanzhang laughed, but it was a pity that he didn't say, "If you are my father", it is a pity.

Lin Daiyu whispered something to Li Qingzhao.

Chu Zhen said: "The current situation, Erlang can grasp it himself, no one can help you." ”

Li Shimin nodded and stopped talking about Chang'an.

Chu Zhen looked at Li Qingzhao and said with a smile: "Little lady Li, how about you talk about Zhao Ji, the Duke of Dude?" ”

"Chu Langjun!"

Li Qingzhao's eyes were resentful, Lin Daiyu laughed out loud, and the fan covered her little face and turned her head.

Zhu Yuanzhang smiled: "Song Huizong is no longer stupid because of you?" ”

Li Shimin drank tea, listened to them talk about the Song Dynasty, and was thinking about his own affairs, even Chu Zhen smiled and said that he would take a group of military generals from the Qin Wangfu and Tiance Mansion to the Song Dynasty to ensure that he could defeat the Western Xia, but he didn't listen to it.

Chu Zhen and the others also saw that he was preoccupied and didn't bother anymore.

Soon after, Li Shimin returned to Chang'an.

Zhu Yuanzhang talked about the radio station again, and went back with a bunch of things.

Chu Zhen still returned to the second floor with the two girls.

Not long after sitting down, Li Qingzhao asked Daiyu: "Sister, your mother is not in Daguan Garden?" ”

"Hmm. My mother went to Fuzhou Mansion in Fujian and Zhejiang, and it may take a year or two to return. ”

Lin Daiyu was a little lost, looked at Chu Zhen with a pair of misty eyes, and then continued: "Before my mother left, I let Sister Qin live in Youfeng Laiyi, saying that when she comes back, her father will also come back, and she won't live in Daguan Garden at that time." ”

"Sister, what about you?" Li Qingzhao looked at her with a smile.

Lin Daiyu glanced at her, "My sister asked what she said, I naturally went home with my parents to live, and no one invited me to live in Daguan Garden." ”

Hearing this, Li Qingzhao laughed hard, looked at Chu Langjun opposite, and said, "Didn't Immortal Chu ask Sister Lin to take care of the garden?" ”

Chu Zhen looked at Daiyu, "Sister Lin wants me to ask you to stay?" Do you still need a salary? ”

"I think about it, I haven't gotten the moon silver from Uncle Chu yet!"

Lin Daiyu stretched out her white and tender palm towards him, and there was a watery smile in her eyes: "Give it to me quickly, twenty taels a month~"

Li Qingzhao said: "If I'm not mistaken, the wife and the old lady of Rongguo Mansion are also twenty taels a month, and now my sister also asks Uncle Chu for twenty taels of silver, could it be my sister...... Not. ”

"Sister is talking again!"

Lin Daiyu hurriedly blocked her mouth with her palm, and the two frolicked, Chu Zhen was fascinated, and they came back to their senses, both blushing.

"Chu Langjun still goes to Daguan Garden first, and then goes to Bianjing with me when he comes back."

Li Qingzhao let her again.

Daiyu looked at her twice, held her hand and said goodbye, and then went back to Xiaoxiang Pavilion with Brother Chu.
