In a flash, five days passed.

These five days, Gu Qianxue is busy and happy.

She went to Haolan academy and Prince Li's residence every day. She personally urged Su Lingxiao to eat and do morning exercises. She also consulted empress Qin and set up her own laboratory. She was very busy.

And happiness, in addition to more and more complete laboratory facilities, there is one of the most happy thing is - Li Wang is going to the West on business.

As long as you think that you can't see Li Wang in the next two months, Gu Qianxue is as happy as a chicken. The closer he is to King Li's departure from Beijing, the happier she will be.

Just as at this time --

"Miss Gu, do you have any happy events? Why do my subordinates think you are in a good mood?" Sun Yu, dressed in sackcloth, was standing next to Gu Qianxue. A few feet in front of them, the craftsmen were carrying a huge porcelain VAT up the hill and fixing it on the rock.

A total of six craftsmen were working. It was a miracle that the porcelain VAT was so large that so few people used it. It was all due to Gu Qianxue's preparation of several iron wheels in advance.

This iron wheel is familiar to people in modern times, and that is pulley. The pulley is divided into fixed pulley and movable pulley. The fixed pulley can change the moving direction of the object, but it does not save labor; the moving pulley can save half the force though it can not change the direction.

By combining the movable pulley with the fixed pulley, and putting on the rope, you can save a lot of manpower. Without this pulley block, the large porcelain cylinder needs a lot of manpower to lift, not to mention the installation. If there are not enough six craftsmen, it is not enough.

But because of the magic pulley block, as long as six people, they have done a good job in the work that these more than ten people can not do.

Today, Gu Qianxue has become the "God" in the minds of craftsmen. If the craftsmen had doubts about Gu Qianxue's drawings, they have done as much as the sacred task given to them by God.

Even in the craftsman circle, some people say that Miss Gu of the Minister of rites is the reincarnation of the founder of the craftsman. Otherwise, how could a lady of a big family and a lady of an official family design so many ingenious objects.

Of course, Gu Qianxue knows nothing about this. She just wants to try to make a water tower and use tap water.

It's not that she wants to develop the productivity of Nanyue country, but it is It's fun.

In the distance, under a shady arbor, fresh fruits and hot tea were placed on the stone table. Li Wang, dressed in a black brocade robe, sat on the stone bench with rich cushions. He held the drawing of pulley block in his hand, and his eyebrows wrinkled slightly.

"Can you tell me how it works?" Li Wang asked the middle-aged man standing respectfully in front of him.

The man was wearing a long blue linen shirt with a loyal face. The calluses on his hands showed that he often worked. This man is the steward of the service department of King Li's mansion, waiting for his master, Li Wang, to ask.

"Back to Wang Ye, I have been studying these days. Although I have figured out how to use it, I still can't understand its working principle." Answer from the steward of the service department.

Li Wang threw the drawing on the table, stood up and looked at the people who were working in the distance. His long fingers were playing with the trigger on his thumb, "did she invent these iron wheels?"

The steward of the service department thought about it and then said, "go back to the Lord, I think It was indeed invented by Miss Gu, because there are very few books about craftsmen. Most of them have read about them in the world, but they have never seen or even heard of these things on the drawings. I think it is really miss Gu who invented them. "

Li Wang's eyes narrowed slightly, and he did not speak again.

Half an hour later, the craftsmen finally fixed the huge porcelain VAT on the rock on the hillside, and used bamboo pipes to lead some spring water from the mountain, such as the VAT, which was filled with water quickly.

The mountain spring flows down to form a small waterfall, which should have been one of the many landscapes in the liwang mansion. Now, because of the porcelain VAT, it is a little strange, and the water of the waterfall is less.

The craftsmen who had just installed the porcelain jar found that they were shaking with fear and came to persuade Gu Qianxue.

"Miss Gu, this porcelain jar can't be fitted!" One of the craftsmen.

"Why?" Gu Qianxue looks at the porcelain jar that is storing water and asks.

The craftsman's voice trembled, "with the porcelain jar No, it's the water tower, which destroys the scenery of the palace. If his highness King Li doesn't care about it, it's OK, but if he's not happy, he'll lose his head! "

Gu Qianxue stretched out his finger at the hill and said with a smile, "don't worry. After another incense stick, you will know its intention. If you really destroy the scenery, take off the water tower."

Although the craftsmen had expectations, they were still worried and prayed that the LORD would not come here at this time.

But nobody knew that Li Wang was watching in a hidden Pavilion.

In less than a moment of incense, the porcelain jar was full of spring water, and the water overflowed along the semicircular and serrated mouth of the jar. Because of the water pressure, the water flowed up like a small fountain, and the water at the edge of the porcelain jar formed a blooming flower.

Because the water beat on the surface of the water, the water burst, flying fog beads countless, beautiful.This is not enough. The sun shines on the fog and water drops, and a rainbow appears. Red orange, yellow, green, blue and purple, the seven color beam is tightly placed in the porcelain vat with white background and blue flowers, while the other side gradually disappears in the water mist, just like a rainbow flying out of the porcelain VAT.

"Wow

"It's beautiful!"

"Too many seconds!"

"This is a spectacle."

All the craftsmen were amazed. Some of them were so excited that they didn't know how to praise them. Sun Yu, a well-informed man beside Gu Qianxue, couldn't help but open his mouth, "Miss Gu, you How did you do it? "

Gu Qianxue said with a smile, "I don't make a water tower for scenery. It has practical use. Let's go to the house." With that, he took the lead in entering the door of Yusheng residence.

Far away, pavilion.

"Color Rainbow Shao Gonggong exclaimed in surprise with his sharp voice.

Except for Mr. Shao, all the servants in the pavilion saw the beautiful scenery. Even though there was a prince on the scene, he couldn't make a fuss. In fact, he was very shocked.

Li Wang was also shocked.

"Why did they go to the house? Isn't the rainbow jar she wanted to make?" Asked Li Wang.

Shao Gonggong held the orchid finger and said, "back to the king, I haven't heard Miss Gu mention this before. Miss Gu said that this big porcelain jar is called water tower. As long as the water tower is successful, the water will flow out of the room after touching the mechanism."

Li Wang frown not loose, "will the mountain spring lead down the pool, to the mechanism valve, such a simple thing still use her so inspiring?" The cold tone of voice was scornful of concealment.

Shao Gonggong said with a smile, "the Lord misunderstood me. Miss Gu did not just lead the spring into the house. She said that as long as there is water on the first floor, it is the organ of the attic, and it can also come out of the water. If you build the third floor, there must be water on the third floor. "
