Chapter 498

In the next few days, with the coming of the new year's day, there was not much to deal with whether it was the east palace or the court hall. Most of the officials were still on their way back to Chang'an in Luoyang. So Li Hong took the 17 Chongwen scholars to Taiyi city after meeting them.

Taiyi city has now expanded a lot. Compared with the original view, today's Taiyi city is more prosperous and more advanced. There are more and more permanent residents. It is about to become a real city.

However, in such a large city, there is no room for the 17 students to develop what they have in their hands, which Li Hong named the spin ball.

However, after Li Hong took them back to Taiyi city again, earth shaking changes took place, and their treatment was further improved. Even their 17 family members were placed in Taiyi city by Li Hong.

Bai Chun and others also saw for the first time that the prince's highness was so serious and persistent that they were like a paranoid and a madman. They put themselves together with the 17 students. Even when they went to bed at night, they all forgot to go back to the manor every once in a while.

However, when Bai Chun did not come back, Li Hong reprimanded Bai Chun every time after he visited him several times. As a result, Bai Chun had no choice but to arrange Wei Tuqi in the forbidden area of Taiyi city and take care of Li Hong at any time.

In front of a dozen students, what Li Hong was able to teach and teach was some rudiments, as well as the inspiration of the time when the steam engine was developed.

Li Hong's only clear thing was that the original steam engine was developed because he had to help drain the water out of the mine. As for other aspects, he only vaguely remembered that it was because of the spinning machine, and then the steam engine was gradually applied to other fields in the process of improvement.

So in a few days, they followed the principle of this steam spinning ball, and under the guidance of Li Hong, they designed another kind of steam rotating ball. However, this steam rotating ball can hold more steam. According to Li Hong's design, two pipes were added, which were said to be used for entering and discharging. One pipe was extended into a huge pool, and the other was a new one It extends into an equally huge pool, but without a bit of water.

As the steam is slowly injected into the steam ball, the horn like copper pipes on both sides of the original steam ball are closed. After the steam is filled, another valve is also closed. The huge steam ball with more than one person is rich in steam.

Seventeen students looked at each other. They didn't know what the Prince wanted when he sealed the copper pipes on both sides and filled them with steam.

Li Hong looked at their puzzled eyes, indicating that they began to spray cold water on the outside of the hollow sphere full of steam, while explaining to them the meager knowledge he knew.

The cold water condenses the steam in the container to form a vacuum, and then orders the person to open the inlet valve. Under the action of atmospheric pressure, the water at the bottom of the mine is sucked into the container through the water inlet pipe.

Then close the water inlet valve, re open the steam inlet valve, and press out the water in the container through the drain valve by the steam pressure. When the water in the container is drained and full of steam, close the steam inlet valve and drain valve, and spray water again to condense the steam.

In this way, the inlet and outlet pipes unconsciously drain all the water in the pool into another pool under the action of the steam rotating ball.

The seventeen students, looking at everything in front of them, explained why they had the inspiration to design this steam spinning ball. However, in Qujiang pool, they saw Li Hong's water cup covered by a thin piece of paper and flipped the water cup, but the water did not flow out. So they were curious to see if the steam could be called So set the steam ball.

Day by day, 17 students accompanied Li Hong. Unconsciously, they had spent nearly a month, but the progress was still in the original stage.

However, Li Hong suggested that they should try to take this thing with them and carry out practical operation in the mine. Maybe they can find some inspiration.

After hearing Li Hong's proposal, all the excited students were delighted. After getting Li Hong's approval and help, they decided to go to a mine after the first day of the year to continue their in-depth research.

At this time, in the East Palace of Chang'an City, all the people in the East Palace headed by Bai Chun knelt at the gate of Lizheng hall.

When his majesty and the queen returned to the palace, Li Xian, Li Zhe and Li Dan, king of Pei, Li Zhe and Li Dan, as well as all the ministers from the three provinces, six ministries, nine temples and five supervisors, including the Jingzhao mansion of Chang'an, and the ministers headed by Zong Chuke, all went to Baqiao to meet the brilliant and powerful majesty and queen who had returned from Liaodong, but only Prince Li Hong was missing!

In this way, the emperor and Empress of the Tang Dynasty began to have a bad face in Baqiao, and looked glum, as if someone owed them money. All the following rituals were hastily ended, and the honor guard simply returned to the Daming Palace.

As for the celebration banquet of the officials in the evening, although it was still held as scheduled when the Prince Li Hong failed to arrive, every minister and his relatives could see that, because the prince's Royal Highness was missing, his majesty and the queen were still hard to be happy.In the morning, they knelt down and knelt down in front of the empress, and then they knelt down and became a person.

"Bai Chun, what's going on? Don't any of you know how to remind the prince? " Wu Mei's face is iron green, usually let him Li Hong mischievous also just, but yesterday's matter, Li Hong is too much!

When the emperor and the empress went back to Chang'an, and when the civil and military ministers and the prince of the Manchu Dynasty were all on the Baqiao bridge, his highness, the prince of the Tang Dynasty, was not seen. This made the royal family lose face and became a joke in the court!

Bai Chun was also frightened by Wu Mei's strong pressure. She knelt on the ground and trembled and said, "back to the queen, my maid passed by ten days ago, but The servants are incompetent and have never been able to see the prince. "

"What? You can't even see him? " Wu Mei was shocked. She thought Bai Chun knew what the prince was doing now, but she didn't invite Li Hong back.

But hearing Bai Chun's words, I didn't expect that even Bai Chun couldn't see Li Hong, which made Wu Mei even more surprised. If even Bai Chun, the most important one in his heart, couldn't see him.

Li Hong would never be absent from such an important occasion for no reason. Although the ritual system was something he had never been interested in, he would never be so indifferent to it. Moreover, several imperial historians supervised and urged him.

However, as Bai Chun said, Li Hong locked himself in Taiyi City, and no one could see him. The Wei Tu Qi, who was the prince's bodyguard, was refused by his impassive "Prince's order, no one can see" no matter who wanted to see the prince.

Curiosity overcame the anger that had been suppressed since yesterday. Wu Mei was patient and looked at Bai Chun, who continued to kneel on her knees, and asked again, "do you know what he is doing in Taiyi city?"

"We're working on something called a spinning ball." Bai Chun replied with a low head.

"Spinning ball? What is that? "

"Back to the queen, I don't know..."

"Nonsense! Bastard, you don't know! As a person around the prince, you don't even know what the prince does. The prince never went to Baqiao. You can't even tell the reason. How can you let this palace spare you? " Wu Mei was white pure answer suddenly aroused anger, looking at the white pure kneeling on the ground, the first time harshly scolded the way.

"The maidservant knows the sin, and the maid should die. Please punish the queen..."

"This is not the time to commit a crime, and you are not qualified to let this palace deal with you! What did he say? Repeat it to the palace from the beginning to the end! There must be no omissions! " Wu Mei was dressed in Queen's Palace Dress and her face was livid, but she did not reduce her elegant and elegant demeanor, as well as the majesty of the empress.

So Bai Chun repeats to Wu Mei the thing that she brought back from Taiyi city a month ago with chongwenguan students.

To Wu Mei's surprise, it was a month! Li Hong even locked himself in Taiyi city for a month and never showed up, or even walked out of the forbidden area! This made her more curious about what Li Hong wanted to do.

"What else did he say?" Wu Mei asked again, but in her tone, she had lost a lot of anger and became much calmer.

"Back to the queen, the crown prince once said that if this thing can be really used by our Tang Dynasty, it will not only bring me endless economic wealth, but also an unprecedented and powerful weapon for our Tang Dynasty to explore the sea. It will also raise the whole strength of our Tang Dynasty to an incredible height." Bai Chun is still low head, and side of the snow and others, because often in the Lizheng hall, wear less, at the moment has knelt on the ground shivering.

"Spinning ball? As you said, something as big as that can bring such huge benefits to our Tang Dynasty? Did he ever tell you when it will be developed? When will you be back? " Wu Meixiu frowned and asked lightly.

"Back to the queen, the crown prince said that it was just a prototype. It would become bigger in the future and would be used in more ways. It can do things that people can't do. Even cattle and horses can't match their strength. If they are developed, they can't run faster than horses..."

"What? Can you run? " Wu Mei looks at Bai Chun in surprise. If she doesn't know, Bai Chun will never lie. She can now order that she should be killed immediately in order to arouse people's hearts and excuse them in the name of ghosts and gods!

Bai Chun is also embarrassed, especially Xiaoxue and others, because when his highness told them, they felt as if they were listening to his highness telling them fairy tales as before.
