You are two moments

Li Yuanying, who was dressed in regular clothes, waited at the gate of Xicheng City with the officials of the palace and the officials of the Jinzhou Mansion...... You don't have to pick up your brother in Chang'an, but you need to stand at the city gate and wait when you arrive in Jinzhou...... As the nine-catty old lady said, the generation is not as good as the generation, a certain year is not as good as a year, a month is not as good as a month, and a day is not as good as a day.

"Yo, it's so fresh, you still know how to come out and pick up so." Li Shimin saw Li Yuanying at the gate of the city through the car window...... The younger brother seems to have gotten taller, or hasn't seen him for a few days, and his eyes are wrong?

Li Yuanying looked at the condescending Li Shimin, crossed his hands, and said: "Li Yuanying, the assassin of Jinzhou, and the subordinate officials of Jinzhou, welcome Your Majesty." ”

It seems that a certain person is very willing to come out to greet you, but in the entire Tang Dynasty, except for Brother A, no one else really needs to stand at the gate of the city. Don't mention the crown prince Li Chengqian, he will not leave Chang'an, more precisely, without his brother, he does not dare to leave Chang'an, for fear of being misunderstood...... Li Tai's degree of favor, before he made a desperate bet, he didn't finish compiling the chronicles.

"You go back in your own car, and we'll go to the government to talk." Li Shimin waved his hand, and the steam car started and drove into the city gate.

Li Yuanying: "......"

No wonder the group of people in Wagang chose to follow you Li Erfeng, Aya is right, Yinjian is not as good as Brother, the burden of the eldest son of the Li family in Longxi is too heavy. The words given by Ayah are not good, Bishamen, one of the four heavenly kings, the king of the north and the heavenly king...... Monks from outside, the scriptures are not easy to read.

"Lord Wang!" Xiao Ruoyuan, who was sitting in the seventh car, shook his hands and shouted excitedly.

Du Che got out of the car and turned to the seat in front, Li Yuanying boarded the car, closed the door, and said with a smile: "You are still sensible, but, Xiao Shiyi, a certain is not in Chang'an, why are you still a pair of dark circles?" Now I can't complain about something. ”

kicked off the seat in front of him and persuaded very carefully: "Du Siyang, don't be too anxious, things can't be done in one day, and Chang'an can't be built in one day." ”

A certain is indeed a little anxious, originally they were just an idea, but a certain guided it to become a reality...... Datang wants to build, and people can't be tired, stupid, and crazy.

"Don't worry, Shiro didn't force me to spin." Xiao Ruoyuan took out the wooden box under the seat, opened it and put the disc out of the window again, and said with some excitement. "Don't you always say that we use paper cranes too wastefully? I will contact Wei Gong again, if I can receive the news, you don't need to send people back and forth if you want to tell us to do anything in the future. ”

Li Yuanying looked at Xiao Ruoyuan blankly and pressed the copper sheet dripping...... No, you didn't get any wired electricity, so you just turned it on to the radio contact...... Are you still human? Have you ever thought about how someone feels? Certain...... A certain is just an ordinary fishing veteran, please let it go!

There will never be a Gatling Bodhisattva in the south, six pure and depleted uranium bullets, one breath of 3,600 revolutions, great compassion and great compassion to cross the world

…… Right?

Another string of "tick-tock" sounds, Xiao Ruoyuan finished recording, and opened Tangli to decipher the sound rhythm...... said with a smile: "Lord Wang, Gong Wei said that Artemisia annua powder is going well, and the cure rate of malaria is very good, so you can rest assured." ”

As for saying that someone should not be too embarrassed, there is no need to tell the prince.

Li Yuanying tried to pull back his distant thoughts, and asked in a very ethereal voice, "Does Brother know about this wooden box you made?" ”

Radio, there are too many places available, the security of Chang'an, the security of Datang, the ships going to sea...... Even in later generations, when communication was very convenient, long-distance ships were equipped with two systems, satellite communication and radio...... Even if the frequency is still very low, with the innovation of technology, will they directly cross the ordinary landline and directly cross over to the mobile phone?

Imagine a brick in the hands of Datang...... At least the officials will be equipped, and if you want to go to Pingkangfang to gather in the future, things will become simpler, and you don't have to worry about the harmony of who to call and who not to call. There is no need to make a special appointment at a wine store or a manor to discuss things, and the frequency of covert collusion will also increase.

"Yes." Xiao Ruoyuan took back the disc, put the wooden box back in place, clapped his hands, and said. "Yuan Gong has reported the situation, but we can't determine the effective distance used, nor can we determine the stability of sending messages, and there are still many tests to do."

We strictly follow the work process of Yunhe Mansion and resolutely do not cause trouble to the prince. Yuan Gong said that the more King Teng won His Majesty's trust, the easier things would be done. If King Teng is involved by us, he doesn't mind cleaning the door of the Dao Gate.

"Don't worry, Your Majesty has agreed to build watchtowers in Chang'an." Du Che turned his head and explained softly. "To verify the accuracy of the message delivered by the wooden box, it will be checked by the flag. Stability takes a long time to verify, and His Majesty agreed to give us a year to improve it, and after three years, it can be used at various border gates. ”

In fact, it is not much different from the principle of paper crane transmission, but there are not many people who can make paper cranes...... Not to use spells or occult arts to disturb the lives of ordinary people is an iron law of Taoism, and violators will be punished together.

Those charlatans are not considered to be in the Daomen, they belong to the side door.

Li Yuanying blinked, and one left for more than ten days...... How did you find the vacuum tube?

Du Che glanced at Xu Jingzong beside him, took out a scroll from his sleeve, handed it to Li Yuanying in the back, and said: "Lord Wang, don't be anxious, the discovery of the wooden box is purely accidental, this is a simple picture, you can understand it at a glance." ”

The main thing is that King Teng drew the drawings of the drawing plate, which made the production of gold wire simple and the production of copper wire very simple.

Li Yuanying put the scroll into his sleeve and glanced at Xu Jingzong...... A certain is not blind. With radio, will radio broadcasting be far away? The speed of the steam car was not satisfied, and the government was already close at hand. stretched his waist and smiled casually: "I read a lot of drawings today, and my brain is out of range, let's not talk about the affairs of Yunhe Mansion tonight, let's talk about some wind and snow." ”

A certain is not the lucky one who spends ten small goals in a month, but a certain is the second-ranked existence among the four demon kings of the Tang Dynasty, Jiang Teng, and a certain must do something to live up to his reputation.

Xiao Ruoyuan pointed to his dark circles and asked, "What does the prince mean by the wind and snow?" Yesterday, a girl, when she saw my face, took a bite directly, scolded me for being a disciple, and wronged me! ”

"Hahaha......" Li Yuanying laughed directly, patted his thigh and said. Your so-called handsome and miserable face is really only your own certification, and it has no effect in the world! ”

Although it did not reach the point of misery, it ...... Compared with Wu Yanzu, who is at the peak of his appearance, he is still slightly better, which can only show that Datang women don't like their faces too white, hahaha......

Du Che rolled his eyes directly, no wonder he would ask if his dark circles were more handsome than others, it turned out that he was disliked by others...... I didn't really want to laugh, I just ...... "hahaha...... Little Eleven, you don't have to be sad, which girl said it, you tell the prince, accept her as a wife! ”

Xiao Ruoyuan: "......"

Thank you!
