The northern part of Jinling is full of people. Groups of people slowly heading north with the movement of hot air balloons in the sky, and occasionally exclaiming.

The soldiers guarding along the streets saw that the people did not cause any riots after hearing the explanation, and couldn't help but breathe a sigh of relief. They then walked up and looked at the sky, sighing at the magical craftsmanship of the prince standing side by side.

In addition to ordinary Bai Ding, there are many mansions of nobles in the north of Jinling City. When they heard the servants shouting, they also looked at the black spots in the sky, including first-rank officials of the court.

When they learned that it was the King of Side-Side-Side-Side-Side-Side-Side-Side-Side-Side-Side-Side-Side-Side-Side-Side-Side-Side-Side-Side-Side-Side-Side-Side-Side-Side-Side-Side-Side-Side-Side-Side-Side-Side-Side-Side-Side-Side-Side-S

The south wind slowly blows the hot air balloon to the north. The three of them don’t know the abnormality in Jinling City below. Not long after, they see the mirror-like surface of Xuanwu Lake.

"I didn't expect that Xuanwu Lake would be more beautiful from the sky, and we must be the first to look down on Jinling City." Zhao Ling'er's excitement did not decrease at all.

"But if Your Majesty knew about this, would you cure Qingyan's crime?" Shangguan Feiyan was a little worried, "As the first person in Feitian, he should be the Lord of Nine Five. Now Qingyan has taken us to the Taichu Palace, and it is very likely that the censors will attack him in groups."

Zhao Ling'er was shocked when she heard this, and felt that the other party was very reasonable, and then looked at Qingyan with a worried look.

"Don't worry, this hot air balloon is just a test piece. If the censors chase me hard, I just need to say that I can help Your Majesty check the safety of the hot air balloon at the cost of my life. In this way, Your Majesty will not only not blame me, but also may reward us three." Qingyan was confident.

"Brother, your heart is so big. As long as you don't sue, it's a blessing. We don't care about the reward."

Qingyan looked at the flint under his feet at this time and said regretfully: "Today's flying journey is about to end, and we will return to the blue sky next time."

On the bank of Xuanwu Lake, Huang Quan led a hundred cavalry to follow the direction of the hot air balloon falling, and finally greeted the three of them in a sea of ​​flowers.

Walking down the vine basket slowly, the two women were still a little immersed in the excitement before. Qingyan walked to Huangquan and whispered: "General Huang, please send this hot air balloon to Yuetang Academy, try not to make a statement."

"Receive the orders of humble responsibilities."

----------------------(I'm a dividing line)

Yuetang Academy, shooting range.

Qingyan and his group of three were welcomed the warmest after returning. In addition to admiring Qingyan's magical skills, they respected the courage of the three.

"Everyone! Fortunately, the three of us were saved from their fate. The hot air balloon flew in the sky for nearly a stick of incense and finally landed on the sea of ​​flowers on the west side of Xuanwu Lake. So I announced this time that our flying trip had achieved a major success!" Qingyan shouted.

Everyone was also infected by this momentum and hugged and laughed.

"I saw that everyone didn't have a meal. Since I was so happy today, why don't I send someone to invite a few chefs to cook for us? How about we chat while eating?"

Although there is a kitchen in Yuetang Academy, it is not hired for a chef. It is rarely used in the past. Most of the students are from poor families and bring their own food most of the time. So when they hear this proposal, they burst into a shocking cheer.

An hour later, the grass in the shooting range was filled with tables and chairs, and a variety of dishes were varied, and the open-air banquet was already completed.

"Everyone, before this, we should toast Dean Su and all the gentlemen in the academy. If we had not had their knowledge and hard work on us, the yellow-haired children, perhaps we would not have achieved what we have today. Come, let's raise our wine glasses and thank you gentlemen." Qingyan gathered the wine glasses across his chest and bowed to Su Ju's table.

"Mr. Respect!" Both male and female students stood up and drank the wine in one go.

Su Ju's expression was very proud, and she sighed inwardly that this kid Qingyan is really good at doing things, and she likes it the more she looks at it.

"I believe everyone should still remember what I said ten days ago. If you want to govern the country, you must recognize the foundation of the country. If all young talents learn to recite poems and write poems, yearn for the height of the temple, and look down on scholars, farmers, industry and commerce, it is a great misfortune for me, Nan Zhao. For example, in this matter today, do you think that poetry, songs and essays can send people to the sky?"

Everyone shook their heads.

"The theory of national policy is naturally the top priority, but is invention and creation inferior? So everyone should develop their interests and expertise. No matter which field is ultimate, they will achieve great achievements."

Su Ju stood up and said, "Qingyan said it well. Today you have seen great achievements that the ancients could not achieve. I must agree with him in my heart. So in the future, you must be down-to-earth and not be ambitious and always think about going out to worship the minister."

"Students are taught." Everyone should have stood up.

Then Su Jie and Qingyan came to the cottage, and the latter briefly explained the principle of the hot air balloon. This inevitably involved air science. I thought Su Jie must have been confused, but Qingyan did not expect that although the other party was puzzled at the beginning, after a lot of inquiries, he had roughly understood the principle of the hot air balloon.

This shocked Qingyan. It seemed that Su Ji was worthy of being the top talent today, and his acceptance ability was indeed extraordinary.

Then perhaps speaking of the excitement, Qingyan not only made simple popular science of air science, but also revealed the known knowledge of kinetic energy, biology, physics, etc. During this period, Su Ji wrote so much, and recorded the so-called theorem formulas of Qingyan one by one.

"What the students said can be remembered and can be guaranteed to be completely correct. The old Taoist priest taught a lot that day, but the student was dull and did not write down all of them." Qing Yan left a foreshadowing for the future teaching Su Ju, and it would be an excuse to think of something else when he had the opportunity.

"Ah... the world is so great. There are such great powers in this world. Su is unheard of any kind you mentioned. But so much knowledge has been enough for Su to learn for several years. It is not too late to tell Su when you think of other things."

"Actually, the teacher should understand what the student is doing this." Qingyan's face was a little heavy.

"Although Su doesn't understand many places, he still has some tricks to figure out people's hearts. You do this just to prevent the good seedlings in the academy from being polluted by this secular world. And to teach Su these things, I also want me to pass them on to these students as a transit."

"What the gentleman said is that if we are always so determined and complacent, one day we will be surpassed by other nations. Just imagine that if other nations have been studying in the field of hot air balloons for hundreds of years and finally created weapons in the sky, can we still shoot with bows and arrows? All we have to wait for is to be slaughtered, so these students are precious seeds. After they are deeply plowed and sprouted, they will surely drive the soil and bloom with flowers."

Even though Su Ju couldn't imagine what the weapons in the sky would look like, she also knew that she was too far behind in a certain field and how heavy the blow to a nation would be.

"Su will keep your feelings in mind and let me study them for a while, and I will definitely impart this knowledge at that time."

"So please sir."

That night, Shangguan Feiyan returned to the mansion. When his father saw his daughter's magnificent appearance, he smiled knowingly and said, "How is it? Is it good to fly into the sky?"

"So you saw it too, dad. At that time, I, Qingyan and Ling'er, were on the hot air balloon."

"Silly daughter, I guess the whole of Yangzhou has known this for a while, and my father is not as bright as ever." Shangguan Bailuqi said: "It turns out that thing is called a hot air balloon. Although the name is weird, the ability of this thing is quite good."

"You are right. Qingyan and General Huang both think that hot air balloons will bring incomprehensible benefits to the army. If the enemy is expected to be the first in war."

Shangguan Bailu had already thought about the future development route and areas of hot air balloon countless times this afternoon, so she was not surprised to hear her daughter's words.

"Even if the hot air balloons grow stronger in the future, my daughter, as the number one person in Feitian, can be recorded in history, especially looking down at the earth with her sweetheart. This feeling makes me, the father-in-law, envious."

Since he has seen through his mind, Shangguan Feiyan has been teased by his father these days, "If you are envious, I will ask Qingyan to make another one for you."

"Oh? Your status in that kid's heart is so important? I guess the hot air balloon is worth tens of thousands of dollars."

"You probably haven't had dinner yet, I'll make it for you now." Shangguan Feiyan ran into the kitchen as if she was running away.

---------------------------(I'm a dividing line)

Because he talked with Su Jichang until late at night, Zhao Ling'er had already returned home first.

As soon as he walked out of Yuetang Academy, Qingyan remembered what happened to Xiahou Sheng before, but it was too late and he did not turn back.

When he returned to the mansion, he saw that the candle was still on in his yard, and Qingyan felt guilty.

"Zhao'er, I had a long talk with Mr. Su, but I forgot the time because I was too devoted. If I came back late next time, you should rest first." Qingyan walked in and saw Dong Zhao sitting beside the bed with a bad face.

"I heard you were in the limelight today?"

Thinking that it was because he didn't inform him in advance that he angered his wife, Qingyan sat next to him with a smile and explained: "There is no such thing as the limelight. It's just floating in the sky for a while. If the wind is stronger, it will probably float to the Yangtze River."

"It's good to float to the Yangtze River. When the time comes, it's time to take a shower in the river." Dong Zhao's jade fingers popped open the salted pig's hand on his shoulders.

"How can that work? It would be fine if I was the only one. There are Ling'er and Feiyan on the hot air balloon."

"Oh, it's natural for Ling'er to be so close to your sister, but I didn't expect that your friendship with Xiaoman Duwei was also so good."

Qingyan suddenly turned around and flipped over the bedding, then looked at the puzzled expression under the bed.

"What's wrong? Could it be that I was too excited in the sky and threw my wallet away?" Dong Zhao said with a smile.

"Not a wallet, I'm looking for something else."

"What?"

Qingyan said seriously: "I'm looking for a vinegar bottle in the kitchen. Is it spilled in the room? Otherwise, why would the room be so sour?"

Dong Zhao was obviously amused by this sentence, but he still tried his best to hold back his smile and wanted to maintain his majestic momentum.

"Hehe...Madam, you don't know my personality. Is it the kind of person who messes with her husband? It's not that the two girls all got on the hot air balloon at that time, how could I let them get out of Taiwan in front of everyone, especially the two are very good friends. Even if I ignore the face of Jun Yun, how could I pass Ling'er's level?"
