Chen Dafu is 40 years old this year, his ancestral home is Fengchang County, six years ago, Chen Dafu came to Chang'an from Fengchang County alone, relying on the money he made from reselling silk, and invested in the brick-burning factory under the name of the Chang'an Merchants Federation, becoming the first batch of veterans of the brick-burning factory at that time. Since then, Chen Dafu's original choice that was not optimistic has helped him embark on a broad road to get rich quickly.

At the beginning, there was a small workshop with less than 100 people, and now it has developed into a large factory that accommodates more than 10,000 workers.

In the past six years, Chen Dafu bought a house in Qinglongfang, married the second daughter of the head of the Jia family, one of the top families in Chang'an, and added a few concubines.

Early this morning, Chen Dafu took a family with a large bag of luggage and took a carriage out of Chang'an City, because today is the first day of the first lunar month, and yesterday the New Year has just passed, and today he will visit his hometown to visit his elders and neighbors.

Sitting in the carriage, the cold outside was suddenly isolated, Chen Dafu took off his fur coat and sat on the chair on the carriage, followed by his wife and the two eldest sons, the favored concubines and sons also sat in the carriage, and the others sat in a carriage behind with many gifts.

The carriage is inlaid with glass, this kind of glass is produced by Nanshan Academy, the texture is much harder than the glass produced by ordinary glass factories, and it is not easy to break, and the carriages of Chang'an now like to inlay this kind of glass produced by the academy.

The sons wiped the mist from the glass window with their sleeves and looked around through the glass from time to time. It's a lot of fun. Chen Dafu did not stop it. He was old and had children, and he loved these young sons very much, so he was very easy-going with them.

"Daddy, look, what is that~"

Chen Dafu was about to close his eyes and pretend to sleep, but his most beloved eldest son was lying in front of the glass window and shouting loudly to him.

"Xu'er, what's wrong?" Chen Dafu asked with a smile on his face.

"Daddy, look at it. Something is flying in the sky! There's still someone moving up there! The eldest son, Chen Xu, seemed to be very excited, and he was tugging at the corner of his clothes as he spoke.

Chen Dafu smiled, he didn't know what tricks his children were doing, how could people fly in the sky, but when he leaned over and raised his head in front of the window, he saw a scene that also surprised him at a glance.

I saw that in the cloudless blue sky, a huge black cloth bag hung in the sky very abruptly, which looked very strange, and I saw a basket hanging under the black cloth bag. I can see people doing all kinds of things in that basket.

At this time, Chen Dafu was also a little surprised, and saw him hurriedly put on his coat. Rushing out of the carriage, his sons hurried out.

The streets of Qinglongfang have always been lively, and today is no exception, but everyone walking on the street is the same picture, raising their heads, staring, staring at the huge strange objects slowly floating in the sky, and their mouths are wide open......

Xu Xingtang's mouth was also the boss of Zhang at this time, and his eyes kept staring into the distance, until the hot air balloon disappeared from view, he suddenly relieved himself, and excitedly pulled Xu Yang's sleeve and said: "Daddy, daddy, it's amazing, that cloth bag can actually fly to the sky with people!" ”

Before Xu Yang could answer, an elegant voice sounded from behind the father and son. "The hot air balloon uses the principle of hot air to float, heats the air to produce buoyancy, and carries people to the sky, this is not magical, this is technology, this hot air balloon ascends to the sky, and it is another milestone in the scientific and technological progress of my Datang, and I will also publish this matter in the newspaper in the next issue of the newspaper, so that future generations can circulate it."

I saw Di Renjie dressed in a winter bachelor's suit, slowly walked out from behind Xu Xingtang, and then saluted Xu Yang and said, "Disciple Huaiying, meet the master." ”

"Hmm." Xu Yang also smiled slightly and waved his hand.

"Wow, it turned out to be Di Ge'er, tell me quickly, what should I do with this thing~ I also want the craftsman at home to make such a cloth bag and take me to the sky for a ride." Xu Xingtang has the best relationship with Xiao Di Xiaowu at home on weekdays, so now he has no scruples and says loudly.

Without waiting for Di Renjie to answer, Xu Yang touched Xu Xingtang's head with caressing, and said to Di Renjie: "This child is about to be spoiled, and God is still shouting about such dangerous things, by the way, Zhao'er and you have been living in the academy for more than a month, I read the articles in these issues of "Datang News", and they are getting more and more exciting, it seems that you are still used to living in the academy?" ”

Speaking of this, Di Renjie scratched his head a little embarrassed and said: "If you go back to the master, it's okay to live in the academy, but Zhao'er has complained many times that the food in the academy is not as delicious as the food in the village, so she still wants to go back to live." ”

"Haha." Hearing Di Renjie say this, Xu Yang laughed out loud, "Zhao'er's mouth is also used to being tricked by the marquis of this county, but it's okay, as long as she wants to come back, the courtyard in the back mountain of the village has always opened the door for her." ”

"That's it, thank you master." Di Renjie hurriedly saluted.

"Oh, Master Xu, how do you look at this king's flying machine?" Xu Yang was chatting with Di Renjie, when suddenly a fat young man in yellow goose down came over and interrupted the conversation between them, which one was not Li Tai, the king of Wei.

"King Wei's flying machine already has a certain level of modern industry, and it is more than enough to use it for military lookout and signal transmission, but." Xu Yang's words changed, "But this kind of aircraft flies slowly, and it can't freely control the direction of action, and it is still far from being able to be used as an aerial combat equipment, I don't remember that King Wei has been researching a flying machine similar to a paraglider before?" That kind of aircraft seems to be the way forward for future weapons to dominate the sky. ”

Hearing Xu Yang say this, Li Tai was like a deflated ball, and said decadently: "This king also remembers what Mr. said, day and night research on this flying machine that can fly to the sky at speed, but those models all failed, no matter how long they traveled, they would not leave the ground, which made this king not think about eating, and finally had to get out a hot air balloon first to relieve the pressure on this king." ”

Seeing Li Tai's haggard expression, Xu Yang also hurriedly comforted: "The masters of the Mo family who are proficient in mechanical arts, and the skilled craftsmen who will be the supervisors have gathered in the academy, and now that my Datang's technology tree is relatively complete, the controllable flying machine will definitely be able to successfully make it, so let's write some matters that need attention when I return to the village, and send it to the academy to show you when the time comes." ”

Hearing Xu Yang say this, Li Tai's originally lost expression instantly seemed to be beaten with chicken blood, others don't know what the things Xu Yang wrote are useful, but as a scientist who stands at the forefront of Datang science and technology, he knows how much information and enlightenment is contained in that small piece of paper, it is no exaggeration to say that as long as it is those problems that cannot be solved, as long as Xu Yang writes down the precautions, then any scientific problem will be solved...... (To be continued......)
