Although Mr. Yan Zhitui does not have any masterpieces, his family is very good, young and old do nothing, repair the history of the country, and make the emperor's living note.

This may not sound like much, but in the era of feudal empires, the status of this family was simply two points higher than that of the most powerful ministers in the court, because they were the only ones who could limit the power of the king.

In the feudal era, the emperor was the biggest, Li Er was lying on his stomach, no one dared to stand, and even the most powerful courtiers did not dare to directly disobey Li Er's intentions, so he could only admonish two sentences when he was in charge.

But the Yan family is different, the Yan family repairs the living note, and the emperor's every word and deed must be truthfully recorded in it, if there is anything Li Er is afraid of in this world, then it is definitely the seemingly thin "Living Note", which is related to all the evaluations of him by later generations, a Xuanwumen incident, Li Er's reputation is not as good as later generations imagined, at least the killing of his brother and killing his brother is enough for him to leave a stench for 10,000 years.

Therefore, Li Er took special care of the Yan family, and specially built the ancestral hall of the ancestor for the Yan family, which was the ancestral hall of Yan Hui, a student of Confucius, and also gave high-ranking officials and concubines, and the children of the Yan family were all secretaries and supervisors.

Mr. Yan in front of him is a great person, and a "Yan's Family Motto" from his hand is listed by Li Er as a must-read for the non-commissioned officer family, which shows his appreciation.

In the face of this big guy, Xu Yang naturally didn't dare to make a mistake, and clasped his fists and said: "It turned out to be Mr. Yan, and the little one is going to return to the village, what does the old man command?" ”

Although Yan Zhitui is old, his eyes are not cloudy at all, he looked at Xu Yang with a bright look, beckoned and said, "It's nothing, I just want to talk to you." ”

Xu Yang was a little flattered, Mr. Yan was pulled into the academy by Li Gang at the beginning, and he didn't have much intersection with him, but he has always respected this person.

"Since the construction of this academy, the old man has been staying in this newly built library, since you sent that batch of reading materials, the old man has been studying those things in your ghost valley for almost a year, and the more I learn, the more ashamed I become." Yan Zhitui said with a half-joking smile.

"The territory of my Datang is now so vast that an old man like me is a little surprised, from Sakhalin Island in the east, to the Yin Mountains and Desert in the north, across the Green Mountains in the west, and to the south, needless to say, it is a place that you have become a sea of stars. Do you know what this vast land means? Yan Zhitui seemed to say to himself: "It means that this is the king of the world, the original lord of today is a world-famous person, and now there is still you to support you, the old man really doesn't know what else in this world can resist my Datang." ”

Hearing Yan Zhitui's praise, Xu Yang smiled and said: "Old Mr. Yan is strict, and it is true that His Majesty is the lord of the world, but the role of the kid is not worth mentioning." ”

Yan Zhitui's eyes flashed with a hint of essence, shook his head, and leaned close to Xu Yang's ear and said: "The craftsman in charge of the research and development of the train in the R&D Department of the academy has already done a good job of developing the train model, and is now taking a group of students to debug it. ”

When he heard that the train was ready, Xu Yang was stunned for a moment, and a sense of joy suddenly rushed to his mind, and he didn't even hear Yan Zhitui's words clearly.

"What?! Is the train built? Xu Yang asked in surprise.

Yan Zhitui's expression was embarrassed, but after all, he was an old man who had lived for decades, and he quickly recovered, nodded at Xu Yang and said: "Exactly, the Pyongyang place in the R&D Department of the back mountain of the academy is now in full swing every day, and yesterday someone from the craftsman department came to borrow the information of engineering drawing. ”

Xu Yang was already excited at this time, with the concept of what a train is, it is an artifact that can break the geographical isolation, this thing can transport a large number of materials in wartime, and can transport people and trade goods in non-war times, in short, the train has a hundred miles and no harm, and the Tang people's open mind is much better than that of the Qing Dynasty, at least no one will propose such a stupid thing as using a horse-drawn train.

"Thank you, Mr. Yan, for telling me, the kid wants to go to the back mountain of the academy to see it now, so he will be rude and retire first." At this moment, Xu Yang couldn't wait to go back to the mountains to have a look.

"Hmm" Yan Zhitui nodded, and saw Xu Yangfeng running away without a trace, looking at the empty gate, Yan Zhitui whispered something in his mouth.

"Looking for crops, breaking Goryeo, killing the Turks, and now the barbarians have also made a steam train, Guiguzi, what kind of amazing person are you?"

"Hurry up, where is Chen Tie, the person in charge of the steam cylinder?"

"Back to Scribe Zhao, Chen Tie has gone to the thatched house."

"If you don't go early, don't go late, but when the train starts the test, does this Chen Tie not want to do it?" I saw a hunched old man wearing a scribe's uniform, pointing at the herald and criticizing.

The little guy was obviously a little frightened, and said resignedly: "Back to Zhao Shu's words, that Chen Tie ate a meal mixed with croton at noon, so now he has a stomach trouble, and I am afraid that he will not be able to come back for a while." ”

When the hunchbacked old man heard this, his beard was about to float up, and he said angrily: "Is this Chen Tie stupid? Why don't you go eat croton by yourself? ”

The little guy was even more frightened, and said softly: "My lord, you don't know, last time Chen Tie accidentally bumped into the prince Li while walking in the academy, and Chen Tie was so stubborn, there were some small quarrels, and the classmate surnamed Li threatened to take revenge on Chen Tie, he has eaten croton four times recently, and then he knew the identity of the person, and he didn't dare to make a mistake, it is not good to apologize or bear the guilt, only blame Chen Tie for his own cheap mouth and scolded the little overlord in the academy"

As soon as he heard the word prince, although the little guy had changed his words in time, the old man was still suffocated, pulled the little guy over, and scolded in a low voice: "You don't want to live anymore, can the affairs of His Royal Highness the prince be spread randomly?" You can't do this in the future, so that the royal forest around the prince hears it, and you don't know how you died. ”

The little guy suddenly became nervous, and stumbled: "I know." ”

"- Scribe Zhao! Lord Xu is here! Just as the old man was reprimanding the little man, this voice came from not far away.

The old man was stunned for a moment, then smiled, and pointed to everyone: "It's all good, it's an honor for our R&D department to come here, I originally wanted to wait a few days, and then call the county master to see the results, but now I didn't expect it to be in advance, one by one, cheer up, don't let the county master see the joke." ”

Looking at the huge iron train in front of him, Xu Yang's eyes have become golden, with this thing, wouldn't it be that in the future, the economic circulation shares of Datang can be accelerated again, and becoming the world's financial center is just around the corner!

"Lord Jun, you see, these are all built according to the drawings you gave at the beginning, every part is in accordance with the requirements, and the error is kept within millimeters, but the railroad track is too expensive, and the students of the academy want to replace it with other things." The hunchbacked old man followed behind Xu Yang and said flatteringly.

"Huh?" Xu Yang shook his head and said: "This rail just needs a lot of metal, you can't save it, and you can't cut corners, otherwise it will be a matter of human life." ”

The old man hurriedly nodded like a chicken pecking rice.

Xu Yang carefully observed from the outside of the train, fortunately, there is not much difference from the steam train of later generations, after all, the drawings are the same, although there is only one locomotive now, but it is also the first step in the research and development of Datang Technology.

Touching the textured iron train, Xu Yang patted the old man's shoulder and said: "Lao Zhao, you are doing a good job, this county lord now wants to see this train start, quickly ask someone to light the steam engine, burn the boiler, turn around and let me see." Xu Yang looked very excited.

"This," the hunchbacked old man looked embarrassed, "the rest of the people have arrived, but the person in charge of the steam cylinder has not come."

"Oh? Why is that? ”R1152
