Cao Shi didn't know that there was a son-in-law upstairs not far away who had a big temper with him, even if he knew, he didn't have to care too much, the little shit of the Tangyi Hou family was a joke of the princes in the Jingshi, and when the husband swallowed his anger, it was a turtle king who watched his wife steal people outside.

It was already past the afternoon when I returned to the Hou Mansion, Princess Yangxin greeted me and complained: "The prince wants to go to Beijing and tell me in advance, I returned from the palace to the palace to find the prince and the marquis, and after several inquiries, I learned that the prince went to Beijing to attend the banquet, and the next time I go to the banquet, don't leave me alone in the mansion." ”

The girl's eyes were faintly watery, and her tone was full of the young woman's obsessive attachment to her husband, Cao Shi smiled and said: "It happened suddenly, the princess went to the palace, and I don't want to go to the palace rashly to tell her, I will definitely pay more attention next time." ”

The people and horses of the Hou Mansion rushed in, and dozens of Huns wearing torn robes attracted the attention of the slaves of the Hou Mansion, and the accompanying guards boasted about today's news and attracted many onlookers, and Princess Yangxin also saw these Huns: "Is this the slave maid that the prince bought from the human market?" Why choose these Huns. ”

Cao Shi glanced at the Huns who lined up to enter the Hou Mansion and explained: "These Huns are extraordinary, you see that more than 50 of them are all young and strong men and women, there are no old people and children, the Huns both men and women will ride horses and bend bows and shoot arrows, the leader is called Gan's father, a Hun nobleman who can speak the Han language, the scholar said that people like him are rare in the Huns, and the door doctor said that this person should be a sharpshooter, and it is good to stay in the house to teach the guards to ride and shoot." ”

"The prince said that they were good, and it must be good to think about them." Princess Yangxin also said indifferently, now the family in the Hou Mansion has a big business, and there are nearly 2,000 servants in the Xinhou Mansion alone, and she doesn't care about raising dozens of Huns at all.

Cao Shi instructed him to take the time to visit Youneshi and ask in advance which nobleman belonged to the land near the Wei River in the north of the Hou Mansion, and he had long intended to open up a piece of land by the Wei River as a real crop for planting.

Princess Yangxin asked strangely, "The prince wants to buy land again?" This manor in the house has 800 hectares of upper fields, or the newlywed degree given to us by my father back then, it is all because the prince was unwilling to go to the Beique Jiadi Lihou Mansion, but I want this remote place outside the city, every time I enter the palace, I have to take a car for two quarters of an hour, which is very inconvenient. ”

Glimpsing that there were only close-fitting maids on the left and right, Cao Shi reached out and grabbed Princess Yangxin's slender jade hand, and Princess Yangxin's face suddenly looked like a red apple: "The prince and the prince are going to be concubines, this place is not a backyard." ”

The royal maids who accompanied the servants covered their mouths with red faces and snickered, Princess Yangxin, who had always been dignified, was like a little daughter-in-law who didn't even dare to say anything and let Cao Shi pull away, the two of them held hands and walked into the backyard without saying a word, bypassing the corridor, and came to the private courtyard where the two lived together.

Seeing her husband's lazy appearance with a smile, Princess Yangxin said coquettishly: "The gentleman bullied me, the concubine's heart is so sad!" ”

"Xijun's heart is bitter, let me rub my heart and liver for Xijun, and it will be warm in a while."

Cao Shi stretched out his big hand, and made Yang Xinxiu's eyes flush with three or two strokes, and when he saw the royal maids staring at him, he took a sip: "Small? (Hoof) did not retreat, and watched the princess's joke carefully and was beaten. ”

The maids knew that the princess and the prince had a good heart, so they snickered and put down the curtain and retreated, seeing that the maids retreated and turned their faces and the hands reached out, Princess Yangxin slapped her big hands away in shame, and said angrily: "The gentleman hasn't answered the concubine yet, why do you want to buy the land south of the Wei River?" Why don't you want to live in Kyoshiri? ”

Looking at his wife's expression, Cao Shi felt the need to spread out with the person next to him to exchange thoughts: "What do you think is the pros and cons of the mansion being set up in Beijing?" ”

"It's close to the palace! Moreover, Jingshi is more prosperous, and you can go to the east and west cities in at most a quarter of an hour. Princess Yangxin didn't want to answer, and the fool also knew that the Jingshi Center was better than the suburbs.

"So how big can our Hou Mansion be in the capital, can it have the scale of three hundred mansions, and is there a reward of eight hundred hectares of fields?"

Princess Yangxin pursed her lips and sulked, everyone in the world knows that the price of Jingshi is expensive, even if the Son of Heaven is rich all over the world, it is impossible to set aside a land of three hundred houses for her daughter and son-in-law to make a new house in Beique Jiadi, one house is equal to thirty steps square, one step is about 75 centimeters, you can imagine how large the three hundred houses are, even if it is far inferior to the smallest North Palace in Chang'an City, it is also one of the largest mansions in Chang'an, and the Son of Heaven has that land It is better to put together a few hundred houses to build a new palace.

His wife avoided him and sulked, Cao Shi reached out and hugged her slender waist: "I know that you dislike that this place is too far from the palace, so my husband promised you to make a carriage that is both light and comfortable, and it only takes a quarter of an hour to travel from here to the palace, how about it?" ”

"Really? Isn't the gentleman joking to cheat on the concubine? Princess Yangxin's apricot eyes were round, and her small mouth seemed to be able to stuff an egg, Cao Shi made a secret appearance, which provoked Princess Yangxin to be coquettish, only that her husband was playing tricks on herself, and she shook her eyes in disgust.

Of course, she would not believe that her husband was thinking about solving the problem of the carriage, the carriage of the Han Dynasty adhered to the two-wheeled chariot of the Spring and Autumn Period and the Warring States Period, since the sudden rise of the carriage in the middle and late Shang Dynasty, the two-wheeled chariot has always been the main role of the war sacrifice, only a few four-wheeled carriages are only used as vases for the emperor's sacrifice, and the steering difficulties of the carriage show and the problem that the axle is easy to break can never be solved.

In his opinion, the two-wheeled carriage can only be used for long-distance transportation of heavy loads in addition to being light and can be used for war, and the convenience of carrying people has been lacking in research, which is also directly related to the humid climate and low productivity of the Han Dynasty.

The most prosperous areas of the county were concentrated on the vast plains on both sides of the river, and in the warm and humid climate of the early Han Dynasty, it was more suitable to give priority to the development of shipping technology, such as Cao Shi, who crossed the Fen River, the Yellow River, and the Wei River by boat to the Jingshi, and there were many merchants, and only the people in the Jingshi needed comfortable four-wheeled carriages.

After a while, Princess Yangxin remembered the question of buying land again: "Our Hou Mansion has 800 hectares of land, why do you still need that piece of land on the edge of the Wei River?" I have checked that the land belongs to the land of Zhang Wuhou Dou Wan's family, and the people of the Queen Mother's family should not provoke it. ”

Princess Yangxin is half warning and half admonishing, the Dou family relies on the grace of the old lady of Changle Palace, it is really as hot as the sun on a July afternoon, and today's Jingshi Chang'an really has no one who dares to provoke the Dou family, it is really the top relatives of Tianzi No. 1, even if they don't dare to blatantly bully men and women to cause trouble, this windfall is also rolling in stocks.

For example, north of the Pingyang Marquis Mansion, near the Wei River, the best fields belong to Zhangwu Hou Dou Wan, this person is the son of Dou Guangguo, the young monarch of the Dou family who was sold as a slave to mine, his father died of illness a few years ago, and there is a sibling sister Dou Juan is the queen of Liu Sheng, the king of Zhongshan.

The relatives of the queen Wang's family all had their tails between their legs, and Gaihou Wang Xin hid at home except for going to the palace every once in a while to pay respects, and he didn't see him do anything, and the three sisters of Princess Yangxin didn't dare to provoke the relatives of Tianzi No. 1.

"Zhang Wuhou Dou is in trouble, but I have to take down this piece of Shangtian for use, and the construction of many water-related artifacts is inseparable from the Wei River." Cao Shi turned to the room and pulled out a stack of freshly made paper, the fragile surface of the paper was yellowed and fluffy, and it was very easy to tear into pieces.

The paper depicts a large wheel-shaped wheel, with dozens of spokes, supported by wooden buildings standing on the bank of the river, and the lower edge of the spokes is immersed in the river water to extract the river water, and is sent to the land far from the shore along the tall bamboo tube frames made of bamboo and wood.

Cao Shi's painting skills are very good, and he deliberately drew a few peasants holding the peasants to look at the appearance, Princess Yangxin was fascinated: "A few days ago, the concubine heard from the Hou Mansion that the gentleman made a new He? Was the picture on it painted by a gentleman? The gentleman's painting is so beautiful, and the concubine is so happy. ”

Princess Yangxin looked happy, she didn't look at the things in the picture at all, she was just a princess with a smart mind, and knowing more about the palace government did not mean that she could understand water conservancy facilities, compared to the paper and beautiful pictures that were closer to life attracted her attention more.

"Whether the picture is good or not and put aside, I drew this picture called the waterwheel, modeled on the wheel with bamboo and wood as the structure, standing on the bank to collect river water to irrigate the field, one day and one night can irrigate more than 100 hectares of dry field, there is this thing can make the river within a mile under the field into the field, the field into the field, Guanzhong grain production can be increased by more than two percent." Cao Shi compared his fingers to the effect of the waterwheel and talked about the benefits.

The climate of the Central Plains is like the Yangtze River basin after 2,000 years, and the eight hundred miles of Qinchuan and the capital Chang'an City surrounded by eight rivers are comparable to the water towns in the south of the Yangtze River.

Princess Yangxin blinked and asked, "Will this thing increase the grain production by so much?" Did the gentleman do a test in the Hou Kingdom? ”

"I haven't had time yet, I was too sick to be able to control the first few months, and I've been busy brewing new things after I recovered, and I only drew this picture a few days ago, and the specific results can only be roughly estimated, but I thought this thing still has a great future." In front of his wife, Cao Shi's face was not red and he was out of breath, anyway, there would be no second person in this world to make a waterwheel.

Princess Yangxin pondered for a moment: "The concubine doesn't understand the role of this waterwheel, but I think that my father will be happy when this thing is made, and my father is most reluctant to see the people of the world suffering. ”
