Fortunately, the wind direction is east today. Huaying Academy is in the east direction. Although the wind is not very strong, it is enough to prevent Xie from flying into Kaifeng City. However, many people in Bian Capital still saw a black spot flying in the air east of the city. Shen Kuo and the others chased Xie for a full twenty miles before the hot air balloon slowly landed in a farmland. Everyone took action together and immediately put the hot air balloon away. They didn't even bother to ask for the hanging basket, and fled back to the residence near Huaying Academy in a hurry.

Wang Jinghui also arrived at this time. After listening to the narrative between Shen Kuo and Su Song, he was happy that the two finally turned the hot air balloon into reality, while complaining in his heart. Could it be that these two top scientists today are in conflict with each other, and as long as they do experiments together, they will make some noise? The last time the incendiary bomb test was even alarmed by the emperor's dragon boat. Fortunately, God helped him, and he did not blow the hot air balloon into Kaifeng City, otherwise it would trigger a riot. Then Shen Kuo and Su Song would have to carry a few bullet stamps on their backs. In severe cases, it was likely that they would be a delisting official.

"Before taking off, the hot air balloon contained three large bags of sand in the hanging basket. It could fly at least twenty miles and at an altitude of at least one hundred meters. It seems that there is absolutely no problem for hot air balloons to ride on people. If controlled properly, it is most appropriate to use it to carry people to observe the enemy situation!" Shen Kuo said excitedly. Although the sudden takeoff of the hot air balloon in the morning scared him, the conclusion now proves that the manned flight of hot air balloons is completely realistic, and people can fly into the sky! This excitement has already concealed his previous fear.

"But the hot air balloon obviously cannot control the flight direction by itself after it is launched. If no measures are taken, it is possible to float to the enemy at that time!" Although Su Song is very optimistic about hot air balloon flight, the experimental accident just now also made him keenly realize the major shortcomings of hot air balloon flight.

"This person is easy. Just use a thick hemp rope to fix it when observing the enemy situation and slowly place it to the required height. Before lifting, you can hang sandbags on the hanging basket. One sandbag and one sandbag can reduce weight to control the height. It is just that it is more difficult to get it down!..."

Wang Jinghui was very happy to see the two of them summarizing the gains and losses of this experiment and the advantages and disadvantages of hot air balloon flight. Although there was something wrong with this release experiment, fortunately, God helped him not blow the hot air balloon into Kaifeng City, but according to the size and flight altitude of the hot air balloon. There must be many people in Kaifeng City that have seen it. At that time, I will inevitably go to Emperor Zhao Xu to explain it. Although it was a bit troublesome, I felt relieved for a moment - it was originally a political show, but now this unexpected experimental accident has saved me from making an announcement. I believe someone will definitely come to question it, and I can just go with the flow.

Wang Jinghui interrupted the two of them with a smile and said, "Mr. Zirong, Brother Cunzhong, it seems that through this unexpected incident, the reliability of the hot air balloon flight has been proved. The rest is to improve the exposed shortcomings. This is not an urgent matter. But is it time for us to enter the palace and face the holy? I believe that many people in Kaifeng City have seen hot air balloons this morning. It would be bad if they don't pass the hot air balloons into something monster that will cause riots. I think we should hurry up and face the holy people to give the holy a explanation that will be explained in the past!"

After hearing Wang Jinghui's words, Shen Kuo's face turned ugly - Wang Jinghui's words were not wrong. If it weren't for the east wind today, the hot air balloon would fly into Kaifeng City, and the people in the city would not know what the hot air balloon was. It would be possible if it caused riots. At that time, they might have to return the "Hanlin Bachelor" that they had just obtained.

Su Song was even more straightforward: "It's not too late to change it. Now we are going to the city to prepare to enter the palace to face the saint. If time goes on for a long time, something may happen!"

As Wang Jinghui expected, although the hot air balloon did not float into Kaifeng City, many people still saw the hot air balloons above the east direction of the city. However, the hot air balloons quickly disappeared from people's sight, which did not cause any disturbance. However, this also became a matter of chatting among some streets and alleys in the city. Kaifeng Mansion also received news, but when they reacted, the hot air balloons had long since disappeared, so Han Wei had to give up in disappointment. Emperor Zhao Xu did not react when he heard the news. Although Wang Jinghui told him about overheating air balloons some time ago, he did not take it seriously, but just laughed it off.

With Wang Jinghui here, it became extremely simple to enter the palace to meet the saint. It happened that there was no one around Emperor Zhao Xu. Wang Jinghui and the other two were soon waiting outside the palace to receive the order to apprentice. On the way to the palace, Wang Jinghui carefully paid attention to the movements on the street. While waiting for the summons at the gate of the palace, he also asked several eunuchs if they heard something strange today. The news returned made him feel relieved. Except for the fact that Xiao Wei from Kaifeng Prefecture seemed to have something to come, there was no major reaction in the city because of the appearance of the hot air balloon. Looking at Shen Kuo and Su Song next to him, they all had relief expressions. It seemed that these two "perpetrators" with a little bit of nerves were also scared!

According to convention, after Wang Jinghui gave each of the little eunuchs he saw, the three of them received high-quality services from the eunuchs while waiting, serving tea, water, and desserts and fruits. Shen Kuo and Su Song had nothing to do with this. They followed Wang Jinghui into the palace for a long time, and they had become accustomed to these things. With the lessons of the eunuchs in the Han and Tang Dynasties, the Song Dynasty had extremely strict requirements for eunuchs. Although there were eunuchs like Li Xian and the eunuchs had their own huge and independent operating system in military industry, these could not make eunuchs do whatever they wanted and become a disaster.

Although the ministers looked down on eunuchs, they would not offend them rashly. They could guarantee that they had no relationship with eunuchs. Apart from Sima Guang, Ouyang Xiu and Wen Yanbo, there was no one else to find. But then again, even these three people gave eunuchs gifts, eunuchs dared to accept gifts. Although Wang Jinghui was a relative of the foreigners, he had always been generous in the palace and was always very generous in the palace. In addition, the eunuchs like to receive the prince-consort the most was Xiao Wang. Without the orders of the prince-consort, all kinds of rumors in the palace and the emperor's mood today were truthfully presented. Su Song and Shen Kuo shook their heads.

"Mr. Concubine, this time I came with my two beloved ministers. Is there any new progress in artillery?" Emperor Zhao Xu said with a smile.

"Your Majesty, I am not here with the two adults to study artillery! The hot air balloon that I told the emperor a while ago that I could take people to fly has been developed. This morning, it flew into the sky because of improper operation. Fortunately, the wind direction is suitable today, so the hot air balloon did not fly over Kaifeng City. If it causes riots, it is my fault. Please forgive me for the crime of improper handling of things!" Wang Jinghui bowed and said.

Although Shen Kuo and Su Song were still bargaining at Zeng Gongliang's home, Wang Jinghui still took on the matter. No matter what, he was a censor's eye. The bullet stamp on his back could be held in a basket, not more than him, and less than him. Anyway, he would not be punished any real punishment. However, Shen Kuo and Su Song were different. Shen Kuo had just become a Hanlin bachelor, and how many people were jealous, but this guy was also a elm-headed man and lacked the sense of political crisis. Being bullet stamped was equivalent to ruining his political future. Su Song was much stronger than Shen Kuo, but he could not be impeached. These two great scientists are important figures in realizing their ideals, and this matter was caused by himself. Wang Jinghui believed that he was responsible for bearing the consequences caused.

"Do you mean that people can fly in the sky?" Emperor Zhao Xu asked excitedly.

After hearing this, Wang Jinghui couldn't help but wipe the cold sweat from his head secretly - it turned out that Emperor Zhao Xu didn't know what was going on now. It seemed that the hot air balloon should have no reaction in the city, which also made Wang Jinghui feel much more relieved. The young emperor had just taken over this huge empire less than two years ago, and various political affairs had already made him feel breathless. However, he was a young man after all, and he had maintained a high interest in any new play. This was also the basis for Wang Jinghui to use this as a breakthrough point to attract the emperor's attention.

"Master, it is impossible for people to rely on their own strength to fly in the sky like birds. However, as the spirit of all things, people can use other tools to achieve this goal - of course, hot air balloons are one of them. Brother Cunzhong, please introduce your hot air balloons to Master!" Wang Jinghui said with a smile.

Although he had an accident in his rash experiment and did not cause any riots to Kaifeng City, Wang Jinghui took the responsibility himself in advance. Shen Kuo was very grateful for this. At this time, he pushed the credit for the development of the hot air balloon to Su Song and himself. He was even more grateful and said, "The idea of ​​the hot air balloon was first proposed by the prince consort. Chen and Zirong just practiced it based on this. The hot air balloon made at present is sewn in sheepskin. Although I don't know how much it can carry, there were several bags of sand on it during the experiment, and its weight was completely comparable to the weight of two people. Even so, it flew to a height of hundreds of feet, and in a very short time it flew to me at twenty miles, so it was completely fine to take people to fly!"

"Haha, since I can take people to fly, can I take a ride?!" Emperor Zhao Xu said with interest.

Shen Kuo and Su Song both scratched their heads after hearing this. No one had ever taken this thing. The emperor's identity is so important. If something goes wrong, even if they present their heads, they can't solve the problem. So both of them looked at Wang Jinghui with help.

Wang Jinghui naturally knew their difficulties, so he said with a smile: "Master, there are still many places for hot air balloons to be improved now. For example, it cannot control the direction of travel. Wherever the wind blows, it will fly in which direction. Therefore, the hot air balloon is very affected by weather conditions. If it is a rash test, there will be unexpected dangers..."

Emperor Zhao Xu felt a little sad after hearing this. He also understood that there were many things that were not done by his own nature. Even Emperor Taizu was not treated with his face several times by his minister Zhao Pu. The emperors of the Song Dynasty were like this. If they wanted to be an emperor and be a good emperor, there must be various rules and restrictions that would surround him.

Wang Jinghui looked at the frowning emperor and continued: "The development of hot air balloons is for the military, but the new technology is not only for military purposes. It should be applied to people's livelihood as soon as possible without violating military secrets."

"People's livelihood?! I won't think about making money with hot air balloons, right?" Emperor Zhao Xu asked in surprise.

Wang Jinghui smiled and said, "Yes, it's very simple to make this hot air balloon. As long as you have a discerning eye, you will know what's going on. So I think there is no need to keep the hot air balloon confidential. Although the prosperity of Kaifeng in Bian is the best in the world, no one has ever been able to stand on a high ground to see the prosperity of Bian Capital. This is a pity..."

Emperor Zhao Xu was lit by Wang Jinghui's words. He didn't care about the "visit fee" of the hot air balloon. However, he could also give himself the opportunity to take the hot air balloon to see how prosperous the Biandu is under his control. This is a fatal temptation. It can be said that in this era, few people can resist this temptation. Among the people on the venue, only Shen Kuo and Su Song were the most regretful. They all blamed themselves in their hearts why they didn't stand in the hanging basket today. Looking at the prosperity of Biandu from the sky, it was so desirable!

"As long as this hot air balloon looks like, it is basically very simple to imitate. To put it bluntly, it is a large Kongming lantern, but the novelty is that it can bring people to the sky!" Shen Kuo exclaimed from the side.

"Sir, I have a suggestion!"

"I'm sorry, but I'm not sure!" Emperor Zhao Xu's mind was obviously not on it, and he seemed to have already flew to the hot air balloon to see the scenery of Biandu.

"In addition to equip hot air balloons in the army for military needs, I suggest that the court can set up several hot air balloons to fly in reasonable locations in Biandu. On the one hand, the people of Biandu can see the prosperous urban scene of Biandu; on the other hand, the income is used to open several free cute schools. Although the income is relatively small, it is also a kind of moral policy. If possible, such hot air balloons are set up in all large cities with a population of more than 100,000 in the Song Dynasty. The so-called gathering of sand to form a tower, the income is already very considerable. It is better to use it to set up cute schools on a large scale.

Using hot air balloons to make money was also what Wang Jinghui had just thought of, but the thought flashed in his heart, which inspired him - sightseeing in later generations was also a highlight of making money. There are so many rich people in Kaifeng, so it is no problem to slaughter a few knives. Pulling out some hairs from these rich people and opening a few free cute learning is no problem. If you can really set up such tourist spots among all the large cities of the Song Dynasty, the benefits will be very considerable...

After listening to Wang Jinghui's suggestions on the application of hot air balloons, everyone present was stunned for a moment - this prince consort could quickly get rich and become the richest man in the Song Dynasty in just a few years. It seems that there is no reason... It's really a fortune in the prince consort's eyes...

Although intellectuals in this era are ashamed to talk about profit, let alone senior intellectuals like Shen Kuo and Su Song and the emperor himself, Wang Jinghui openly negotiates business with the emperor under the banner of establishing free and cute schools. This ability is the first in the Song Dynasty. It is really irresistible.

"This... my dear advice is very good, but you still have to wait until the ministers and the envoy of the two prefectures discuss before you can make a judgment..." Emperor Zhao Xu said a little embarrassedly.

"The improvement of hot air balloons will be completed soon. After a few more experiments to verify their safety, the emperor can be in the palace or browse the boundless scenery of Biandu!" Wang Jinghui said with a smile. He was not in a hurry. No matter how anxious he was, it would be useless. It would be better to put some effort into making the hot air balloons ready to enjoy it earlier. Maybe this would be better to speak. He believes that the commercialization of hot air balloons has a broad market in this era when entertainment projects are lacking. He also firmly believes that after the emperor and the ministers have a good time, it is hard to forget the feeling of flying, and commercialization is imperative to popularize it among the people!

In order to avoid the rise of hot air balloons causing commotion among residents in the Biandu City, the hot air balloon's liftoff experiment site was transferred to the military camp camp where the imperial guards were stationed in the far east of the city, and also greeted Kaifeng Prefecture. In order to avoid the swagger of hot air balloons, the balloons were painted white. The most lively topic among residents of Kaifeng, Biandu City in the past few days was the huge monsters rising from the suburbs. Many people took buses to the suburbs to watch the hot air rising in the air. When they came back, they regarded it as the capital to talk to their relatives and friends. This was an announcement for Wang Jinghui's free "commercialization of hot air balloons".
Chapter completed!
