Zhu Yijun wanted to do a balloon to review the three armies, but the safety factor of the hot air balloon was too low, in order to improve it as soon as possible, Xing Shangzhi has been directing his craftsmen to work overtime these days, and for this reason, the prisoner sacrifice ceremony originally scheduled for the third day of the third month of March had to be postponed to March 15.

When Zhang Jialin was asleep in the firewood shed of Buyunzhai, Zhang You was picked up from the bed by Zhang Whale, saying that Zhu Yijun had just secretly flown a hot air balloon made by the royal pre-work in the Qianqing Palace, and he was very excited, and asked him to enter the palace to see the driver, probably to share his mood at the moment.

As for the name of the hot air balloon, through Zhang You's mouth, Zhu Yijun confirmed that it has replaced the "big Kong Ming lantern" and become the official title, from this point of view, even if Zhang You does nothing in the future, just the identity of the producer and name of the hot air balloon is enough to be passed down through the ages.

Later generations are not counted, Zhang You is still the first time to come to the Qianqing Palace, with Zhang Whale from the "Tiger Hole" out of the hole, I saw a hot air balloon painted with a golden dragon hanging in the air, the flame in the hanging basket below, but the hanging basket did not leave the ground, but was firmly tied to the Jiangshan Sheji Pavilion by the rope, surrounded by Han generals, the torches were bright, as if it was day.

When I got closer, I saw the slightly chubby Zhu Yijun walking around the hanging basket with his hands behind his back, looking up at the balloon above from time to time, and his expression was really excited.

"Long live the old slave, the old slave called Zhang You to you." Walking closer, Zhang Whale knelt down from a distance and said with a smile. Zhang You was busy kneeling down to salute, funny in his heart, this Zhu Yijun is really a child's heart, didn't he just choose nine concubines, don't accompany them to turn the dragon and phoenix, but have the leisure to play hot air balloons, it seems that this hot air balloon is not an ordinary like.

The prisoner sacrifice ceremony was postponed to March 15, and the draft was not postponed, as recorded in history, Zhu Yijun selected nine concubines in one go, among which there was Zheng Chengxian's daughter Zheng Mengjing, as for Wang Jinxia, I don't know if she didn't use her real name or what, but she was not among the nine concubines (the historical records should be in August and September).

"Get up, your legs and feet are not good," Zhu Yijun glanced at Zhang You, casually commanded, moved his gaze back to the balloon painted with a golden dragon in the sky, and said happily: "This hot air balloon is really good, I personally sat on it and flew it, although I didn't dare to fly too high, but most of the Forbidden City was really shocking, and I was almost parachuteed, they said that they wouldn't let me try, otherwise on the day of the prisoners, I would fall from the sky, and I wouldn't have scared those captives into peeing their pants?" ”

"Not only those captives, but also the civil and military officials and the people who watched the ceremony saw it, and they were also convinced, and shouted long live, calling Your Majesty the real Heavenly Khan!" Zhang You said jokingly.

Zhu Yijun squinted with a smile and said: "I like the title of 'Heavenly Khan' tightly, in the past, Tang Taizong opened up his territory and conquered all ethnic groups, and was respected by the world as the Heavenly Khan, but he never really flew into the sky, right?" Although I am not talented, with this sharp weapon in hand, I will build a flying army and get it 10,000 hot air balloons, what kind of Tatars, and also try to destroy the barbarians in Linan? ”

"Long live the Lord has this great ambition, he will be able to merit the two ancestors, the power of the state, the generation of the Lord, long live my emperor, long live long live!" Zhang Whale saw the crack and slapped the fart, and before the words fell, the general of the Han Dynasty next to him and all the people knelt on the ground in unison, and shouted in unison: "Long live my emperor, long live, long live!" The voice was majestic, reaching into the sky, and even the balloon was shaken a few times.

In the voice, Zhu Yijun's waist was straight, full of red light, high-spirited, looking at Zhang You, it became more and more pleasing to the eyes, and after signaling everyone to calm down, he pulled him straight to the main hall of Qianqing Palace, and said as he walked: "This is all the credit of Aiqing, Aiqing's brain is different from ordinary people, and the knowledge of Gewu is very tight, not only came up with the idea of Kong Ming lantern, but also parachute and glider, with these two things with hot air balloons, I am afraid that nothing can stop my big soldiers." ”

Zhang You's heart moved, and said: "Not only these, but also those fierce fire oil used for ignition on the hot air balloon, the wind cannot be extinguished, and the water is difficult to extinguish. ”

"Well, I also thought of this, didn't I say that the fierce fire oil was obtained from Li Chengliang, a few days ago he entered the palace to see the driver, I have informed him of this matter, let him buy a large number of them. In addition, I also greeted Zeng Xingwu of the Ministry of Industry and asked him to send someone to find out the origin of the fierce fire oil...... I have a hunch that as soon as the hot air balloon comes out, the way of future warfare will change greatly, but unfortunately you have no fame, and you are still a medical student, otherwise I would have to reward you as a general for your work, and let you take charge of the flying army alone instead of me, and build a world-class career. ”

Zhang Whale followed beside him, enviously pouting his teeth, but Zhang You said: "Your Majesty, Weichen is not the material to be a general, it is better to stay by Your Majesty's side, and it is good to be a little imperial doctor." After a pause, he said: "Your Majesty is far-sighted, in a word, this is the charm of Gewu, such as the appearance of hot air balloons, which will change the development of future wars; The emergence of new agricultural tools will ease the work of farmers and increase grain production; The emergence of new looms will reduce the difficulty of weaving and speed up the weaving speed...... From this point of view, Gewu is definitely the first driving force to promote the country's strength! ”

"Well said!" Zhu Yijun's eyebrows fluttered when he heard it, and he felt that Zhang You's statement was much more interesting than the words of those old masters who opened their mouths and bowed their mouths and sanctified the royal road, and they also heard a lot, so he couldn't help but be curious, and asked: "Since you respect Gewu so much, you are afraid that there is not only the idea of a hot air balloon parachute glider in your mind, right?" Is there anything else? In addition, you have been pondering the knowledge of these objects all day long, and the name of the divine doctor can't be obtained, right? ”

These days, Zhang You has been pondering the good prescription of Zhongxing Daming, and deeply feels that the first thing that needs to be changed is people's outdated concepts, and it is rare that the time is right, so it is natural to "science and technology is the primary productive force", which is known to everyone in later generations, and instilled it in the Ming Emperor Zhu Yijun after packaging.

Judging by his reaction, the effect should be not bad, otherwise, Zhu Yijun is afraid that he will not have the heart to joke in the name of his miracle doctor.

He smiled and didn't refute, but said: "Your Majesty, don't say it, Weichen really has a lot of ideas in his head, such as Weichen ordered someone to make a wheelchair, the seat is lined with springs that can cushion shocks, and the wheels are wrapped in cowhide lined with cotton, which is not only comfortable to sit on, but also has handrails, and can move forward without being pushed." For another example, there are too many dishes when eating, and it is inconvenient to clip them, so Weichen found a way to make a table that can turn the tabletop, so that it is much more convenient to pick up the dishes......"

In order to arouse Zhu Yijun's interest, he didn't care whether there was a physical object or not, he picked up the small inventions of later generations that can be realized with today's scientific and technological level and said five or six kinds in one breath, Zhu Yijun's eyes were straight and dumbfounded, and he looked at him like a monster.

Zhang Whale was also moved when he heard it, where is this special miracle doctor, he is clearly a geek, a fan driven by water, a table that can turn the table, and a telescope made of crystal...... Where did he get so many weird thoughts in his head? Long live Lord likes him so much, I don't know if it's a blessing or a curse!
