On this night, the north wind howled.

The first month of the first year of the overlap of the Great Song Dynasty coincided.

In the next few days, Zhao Guan's family passed Huang Jie to enter the palace, or went straight to the construction site of Wansui Mountain, and soon finalized the design of two large and one small three fountains.

Two of them, one is next to Yaohua Palace, on the side of Qujiang Pond, designed as a lotus-seated 9981 artesian (natural water pressure) fountain. The other is on the bank of the wild goose pond under Shoushan Mountain in the south, and it is shaped like a gourd-shaped 7749-eyed Hiro-style fountain.

There is also a small fountain, the position is the highest, in the north mountain is also the peak of the highest peak of the Banzai Mountain, although it has a unique eye, but the cost and technical content of this fountain is also the highest, it is the method of using manpower to drive the waterwheel to lift step by step to lead the water from the bottom of the mountain to the reservoir on the top of the mountain, and then make the fountain erupt regularly according to the hour scale in the way of sealing and pressurization, erupt four times in an hour, each time a stick of incense time, and also require that the water column that spews out must reach the height of three feet and six feet.

In addition, in order to build this fountain named "Tianshi Spring" by Zhao Guan's family, Huang Jie also asked to find the descendants of Su Song and Han Gonglian, who made the "Water Transport Instrument Elephant Platform" when Shenzong.

This water transport instrument is a large-scale astronomical instrument designed by Su Song and Han Gonglian in the first year of Yuan You (1086). It is a comprehensive observation instrument that integrates an armillary sphere for observing celestial phenomena, an armillary sphere for demonstrating celestial phenomena, a mechanical device for measuring time omissions and reporting time, and is actually a small observatory.

The whole instrument is about 3 zhang 6 feet (about 12 meters) high and about 1 zhang 8 (7 meters) wide, and it is a wooden structure building with a narrow top and wide bottom, in the shape of a square platform, of which the armillary sphere and other instruments are made of copper. The whole Taiwan is divided into three compartments. The lower compartment includes the time striking device and the power mechanism of the whole Taiwan. The compartment is a secret chamber where the image is placed. It took seven years to complete the upper partition of a prefabricated house with an armillary sphere in the middle, and it is now located in the southwest of Tokyo City, and it is still in operation every day.

It's just that it is the craftsmen of the Ministry of Industry who maintain the water transport instrument platform now, not the descendants of Su Song and Han Gonglian, so Huang Jie came up with the design of "Tianshi Spring" in order to find the descendants of these two.

In this regard, Zhao Guan's family naturally agreed, and hurriedly sent someone to investigate.

The descendants of Su Song are easy to find, Su Song was originally in the second year of Qingli (1042) to ascend to the Jinshidi, the official to the criminal department of the book, the official department of the book, Zhezong when the prime minister. Later, he was the envoy of Jixi Guan, and in the fourth year of Shaosheng (1097), he was appointed as the young master of the prince. Hui Zongli, entered the prince Taibao, and was awarded the title of Zhao Jungong. Died in the first year of the Yasukuni Kingdom (1101) at the age of eighty-two, posthumously presented to Sikong, and later posthumously awarded the Duke of Wei. Emperor Lizong of the Song Dynasty pursued Zhengjian.

His ancestors entered Fujian with Wang Chao at the end of the Tang Dynasty, generation for the southern Fujian Wang clan, his father Su Shen once served as the Jixian Palace, and now the heirs are mostly officials in Fujian and Zhejiang, and it is simple to find a person who understands the water transport instrument and elephant platform from it.

It's just that Han Gonglian's descendants, but it is difficult to find, all over the records of the Ministry of Officials, but it is recorded that in the first year of Yuan You, Han Gonglian was the official of the Ministry of Officials, and Su Song, the secretary of the Ministry of Officials, was ordered to inspect the armillary sphere used by the Taishi Bureau, etc., and wanted to make a new instrument. Su Song visited Han Gonglian and learned that he was proficient in mathematics and astronomy, so he told the previous generation of astronomers Zhang Heng, Liang Lingzan, Zhang Sixun and others about the outline of the instrument method, hoping that he could find out the root and imitate it. Han Gonglian wrote a volume of "Nine Chapters of the Pythagorean Test Hun Tian Shu" for this reason, and caused a wooden wheel sample, Su Song thought that although it was not as good as the ancients said, but the design of the water transport wheel was unique.

In the second year of Yuan You, Han Gonglian was appointed as a system official, and began to make, to Yuan You three years, he and more than 200 craftsmen made a large wooden sample for inspection, Yuan You seven years The instrument was finally completed, and was named Yuan You armillary instrument.

After the completion of the water transport instrument platform, Su Song, inspired by the proposal of the Hanlin scholar Xu Jiang and the family collection samples, decided to build an instrument that people could enter into the house to observe the stars, and the specific design of the instrument was still in charge of Han Gonglian. Crafted over several years, the celestial sphere is as tall as a man, and its structure may be made of bamboo, covered with silk paper. There are small holes in the sphere corresponding to the stars in the sky, and people can see a little light in them, like stars in the night sky. When the pivot is pulled inside the suspended ball to make the ball rotate, you can vividly see the infestation of the stars.

According to the documents of the Ministry of Officials, Han Gonglian also resigned in the first year of the Yasukuni Dynasty in Jianzhong, and returned to his hometown of Dezhou on Hebei East Road.

However, this problem is obviously not a problem for Zhao Guan's family, and he didn't do it himself, so he asked Liang Shicheng to write a decree and send it directly to Dezhou, recruiting Han Gonglian's descendants to enter Beijing to face the saint.

In a blink of an eye, it was the sixth day of the first winter month, early in the morning, in the hazy sky, it was sprinkled and drifted this winter, and I don't know if it was the fourth or the fifth snow, Huang Jie wore a gray robe lined with goose down inside, and wore a variegated fox fur coat, kicked a pair of mink boots, covered his head with a snow hat, and Yue Fei, Lin Chong, Cao Zheng and Mo Da and others had been waiting outside the Dailou gate in the south of the city for a long time, looking at the road to the south from afar.

Originally, the brigade from Huangzhou said that it would only take more than ten days to arrive in Tokyo, but who knew that the road encountered cold and snow, and the road was blocked for several days.

After a while, there were constant cars and horses on the road, but they were all people entering the city, although Huang Jie was not in a hurry, but the others were a little unbearable from the early education wind and snow. At this time, a long car with an oil wall came from the city, and after driving to a close place, he saw that the curtain of the car was lifted, and Feng Yinu was wearing a Song Jin cold coat outside, and he was wearing a phoenix crown and a xia veil inside, so he fell into the car with the support of the two maids, Huang Jie seemed stunned, and hurriedly turned over and dismounted to help, and said: "It's cold outside, why did you come?" ”

Feng Yinu let Huang Jie help him, and then said to Huang Jie with angry eyes: "If it weren't for the concubine's body to ask this morning, I don't know how many sisters arrived today, wouldn't it make the concubine lose her manners?" ”

Huang Jie was happy when he heard it, so he said: "Today is an auspicious day for you and me, and you haven't passed the door yet, what kind of rudeness do you say?" ”

Feng Yinu also glared, and Huang Jie also relented, and said, "Okay! All right! It's just that it's cold, and you don't have to blame for the hardships! ”

Feng Yinu turned around and said to the two maids: "Don't hurry up and prepare, so that the uncles can get rid of the cold." ”

The two maids agreed, and they got busy with the driver who was driving the car, and quickly moved down the folding stool, folding table, brazier, food box, and even a huge folding umbrella from the car. ”

Feng Yinu smiled and said nothing, but the maid called Qiaoling beside her said with a lot of mouth: "The master doesn't know, the ninth lady got up on the fourth watch, and before the fifth watch arrived, she called the whole uncle to go to the master's mansion to ask." (To be continued.) )
