Briquette stove in the palace after a period of trial in the Yizhou market began to sell, this new heating tool appeared in Yizhou caused a lot of sensation, not only Yizhou locals, but also outside businessmen also squeezed their heads to buy some to take back, but at this time Li Su let Guan Sixing promulgate a purchase restriction order, stipulating that only Yizhou locals with ID cards can buy briquette stoves, because although Taoyuan has begun to produce briquette stoves in batches, but in the face of a large number of people, Taoyuan's productivity still can't keep up, so for a while, Li Yu only plans to sell briquette stoves to locals in Yizhou.

As for other places, we can only wait for the market here to be saturated, and in the face of Li Su's measures, some foreign merchants are very dissatisfied, but their arms can't twist their thighs, and they have no choice but to wait for the day when they can open for sale.

After staying in Hedong Road for more than a month, Tong Nian brought back all the coal accumulated in Hedong Road, and brought the merchants' demands to Li Su, "Your Highness, the purchase of coal in Hedong Province is very smooth, we have made a lot of money, but the merchants seem to be very interested in our steamships, and His Royal Highness said in the past that he wanted to sell steamships to make up for the deficit of the shipyard, and now I don't know if I can produce some to sell?" "After Tong Nian came back from Hedong Road, he told Li Su about the demands of the merchants, not only in Hedong Province, but now the merchants in many places are thinking about buying steam ships, because during this time they have fully felt the power of this kind of ship, and it will only be a short time to pull their merchant ships down a large distance.

Taoyuan's hot air balloon driving technology has matured, Li Su originally planned to go to Taoyuan to try the feeling of riding a hot air balloon, after all, in modern times, this hot air balloon project is also an aristocratic sport, but he took Cui Yingying and Su Moer before he went out, he met the oncoming Tong Nian, after listening to Tong Nian's words, Li Su sighed and said: "Well, it can be sold." However, let the shipyard produce some low-tech content for them, and our steamships still have to maintain an advantage. ”

"This old slave understands!" With Li Su's permission, Tong Nian hurriedly said, in this way, the Tang Chamber of Commerce has another source of income, and the sale price of this steamship will definitely not be cheap, so it must be a big profit.

Seeing Tong Nian standing silly, Li Su said: "It's just right that you're here, come to Taoyuan with us." There's a new gadget today, let's go and experience it together. ”

Tong Nian looked behind Li Su, Cui Yingying, Su Mo'er, Qin Huaiyu, Zhu Youzhi, Shangguanyi, and the Zheng sisters were all there, and they were surprised. I don't understand what can bring together the core personnel of Yizhou.

In fact, not only Tong Nian didn't understand, but even the people behind Li Su didn't understand, they came to the palace after getting Li Su's notice, and Li Su was going to take them to Taoyuan without saying a word. A mysterious look that makes them scratch their heads.

"Let's go!" Li Su smiled and waved his hand, and the horses were already ready outside the door.

When he arrived at the mouth of Taoyuan Valley, Li Su met Li Ran, who was waiting there. He said, "What's the matter, can you take off now when it's safe to do so?" ”

"Your Highness, rest assured. After the hot air balloon has been modified, it is not as safe as before. With that, he and Li Su walked inside side by side.

Seeing Li Ran, everyone showed strange expressions, not long after Li Ran came to Yizhou, he became Li Su's confidant, in this regard, Li Su's former old subordinates were of course very unhappy, so they and Li Ran came to a debate on government affairs and military affairs, and after that, they didn't dare to say anything, they finally understood what is called knowing astronomy and geography, and the meaning of being knowledgeable.

The expressions of the others were weird, but Qin Huaiyu's expression was frightened, after all, he had seen Li Ran turn his head into a waist-length like a trick.

Hearing this, Li Su showed a hearty smile, and while asking about Li Ran's situation, he was walking inside, and at this time he could already see the hot air balloon floating in the sky.

"Your Highness!" Seeing the arrival of a group of people Tong Yu immediately greeted him, one by one and greeted everyone, when Tong Nian, he showed an unnatural expression, although the father and son are father and son, but maybe because of the ideological gap, they always can't talk together, the two will talk together when they say a few words, and because of this, the two of the father and son are staring at each other when they meet.

"Humph!" Sure enough, seeing Tong Yu's appearance, Tong Nian snorted, focused his eyes on the hot air balloon in the sky, and showed a look of surprise.

Seeing this scene, Li Yu hurriedly changed the topic and said, "How about this hot air balloon?" Have you tried it? ”

Speaking of this, Tong Yu's spirit immediately came, "Your Highness, I have already ridden, it is really amazing, it feels very wonderful, especially when you rise to the sky, you can see Yizhou City in the sky above Taoyuan." ”

"It's too dangerous, won't it fall?" Cui Yingying said, looking at the things in the sky with some concern, could it be that Li Yu just let them ride this today, and several girls looked at each other with a look of fear, after all, they had never seen this kind of thing, but they had just heard that this was called a hot air balloon.

"Don't worry, princess, we have tried it hundreds of times, the safety is very high, there will be no accidents, and there are protective things on it." Tong Yu explained.

Li Yu listened to Tong Yu's description and was even more eager to try, and said, "Let them come down one, and this king will go up and try." ”

"Yes, Your Highness!" Tong Yu turned around and said something to a craftsman, and then the craftsman waved the flag, and there were also people on the hot air balloon who waved the flag in response, and after a while, the hot air balloon began to slowly descend.

"Who dares to ride with me?" Li Su said to the group of people he brought.

Shaking his head almost at the same time, not only Cui Yingying, but also Qin Huaiyu, a bold figure on weekdays, also showed a look of fear.

Li Su smiled evilly: "Qin Huaiyu, Zhu Youzhi, you two come up with me, it's really useless, you still want to please girls with this bit of guts, don't you know what it means to be a beautiful woman loves a hero?" You're all black bears. ”

Hearing this, Qin Huaiyu and Zhu Youzhi showed a constipated expression, the two of them each looked at Zheng Binglan and Zheng Binglu, only to see that both of them looked at them with bright eyes, Zhu Youzhi suddenly felt full of pride in his heart, and patted Qin Huaiyu's shoulder, "If you don't dare, forget it, I'll just come!" ”

"Who wouldn't dare!" Qin Huaiyu and Zheng Binglan immediately straightened their chests and said, and then walked to Li Yu first.

Someone hit the head, and the others suddenly felt that their faces were gloomy, and Dou Xiande and Wang Yinlong also hesitated to step forward.

At this time, there were two hot air balloons floating in the sky, both of which were purchased by Li Su from modern times, if it was self-produced in Taoyuan, he still didn't dare to try it, and Li Ran modified this hot air balloon after seeing it, so that the combustion system was more stable, so as not to turn off halfway.

Just now, everyone looked at the hot air balloon in the air and didn't feel anything, but when the hot air balloon landed, everyone showed a surprised look, because the hot air balloon more than ten meters high was not a behemoth for them.

"Guys, go up!" Li Su said with a smile, he was also a little timid when he said it, so he grabbed these people to be brave.

The Adam's apple squirmed, Qin Huaiyu's face was a little pale, but he still boarded the hot air balloon with the help of the hot air balloon driver, and the others also climbed up in turn.

When everyone stood up, the hanging basket shook, the hot air balloon slowly rose, and Li Su's eyes began to look down at the people below.

"Your Highness, isn't there really no danger?" Cui Yingying shouted at him after the hot air balloon rose five or six meters, and Su Mo'er also showed a worried look.

Li Su gave them a reassuring look and said, "Don't worry, nothing will happen." ”

The hot air balloon rose quickly, and after a while, the voices of the people below gradually became less clear, and at this time, Li Su also began to condescendingly enjoy the surrounding scenery.

"Your Highness, how long are we going to fly?" When he said this, Qin Huaiyu's face was a little pale, and his legs actually began to tremble.

Zhu Youzhi was also very nervous at first, but after the hot air balloon rose, he gradually began to show a relaxed look, enjoying the surrounding scenery like Li Su, after all, for them, this flying is an unattainable thing, and the high sky is the existence they look up to, and now they finally experience the taste of a bird flying in the sky at this time.

Zhu Youzhi smiled: "Huaiyu, you are afraid of heights, right?" ”

As soon as these words came out, several people showed curious looks.

"I don't know, but I'm scared when I look down there." Qin Huaiyu said.

"Hahaha......" Several people laughed heartlessly, it turned out that Qin Huaiyu also had something to fear.

When a few people were talking, the hot air balloon flew higher and higher, and after a while, the people below couldn't see clearly, this was Shangguan Yi, who was facing the west, pointed to the west and said, "Your Highness, it turns out that you can really see Yizhou City!" ”

When everyone heard this, they all looked in the direction he was pointing, and saw a square city in the distance standing on the ground, and in the south of the city there was a large river shining with silver light, on which black spots could be faintly seen, but it was a boat shuttling back and forth.

"Your Highness, can you fly above Yizhou?" Dou Xiande looked forward to it, and the panoramic scenery really shocked him, and his heart was excited.

"I don't want it!" Qin Huaiyu squatted in the basket with a cowardly expression.

Everyone looked at him with disdain, and Li Su said: "Let's go down first, put General Qin on the ground, and let's play slowly, how about it?" ”

"Not bad."

"Great"

“……”

Everyone agreed. (To be continued......)
