Han Qing sat in the boat and looked out, his grandfather and Xie Yi Chuyuan were standing on the deck, pointing to the map and not knowing what to say. Pen & Fun & Pavilion www.biquge.info stayed on the boat for a few days, saying that it was out to let off steam, but in addition to the green trees and green mountains on both sides of the waterway, there was really nothing else to see. Occasionally, he docked at the shore for supplies, and his grandfather only allowed Shoushan to help him buy some local food and fun, in addition to relieving Han Qing's boredom, he also took it back for his brothers and sisters to play. Of course, there are interesting jewelry fabrics, and Han Qing will also prepare some for her grandmother, aunt, and maids.

The water system in the south of the Yangtze River is huge, and it is not only a granary, but also a hard-hit area of flood disasters. Although the imperial court often allocated funds to build dikes in the Yangtze River valley, every time a flood hits, it is inevitable that the dikes will destroy the fields and flood. At present, it appears that there is no other way to prevent flooding than to strengthen the levees.

Although my grandfather is old, he still cares about the people, and he has been a little bit of a waste of sleep and food in the water conservancy survey these days. This trip is simple, there is only Shoushan as a domestic servant, and a mother-in-law who cooks, and because Han Qing didn't bring a maid, he usually dresses up as a boy, so Xie Yi, the elder brother, while accompanying his grandfather and prince, also took on the responsibility of taking care of Han Qing.

Prince Chu Yuan didn't bring his father-in-law when he came to Jiangnan this time, so he only brought two guards with Xie Heng when he went out to investigate. A group of eight people, including the crew, is only more than a dozen people. Xie Heng was about to set off from Hangzhou to survey around the Taihu Lake water system, Han Qing looked at the map, and found that the Songjiang Mansion he passed through when he came back should be the Shanghai area of his own time and space. Although the boat was boring, thinking that there were few opportunities for the ladies to travel in ancient times, Han Qing's mood improved again.

Chu Yuan turned around and saw the little boy sitting in the window lattice, looking over here with a smile on his face, feeling extremely cute. So he said in a loud voice: "Aqing, did you find anything interesting?" ”

"No, it's just that I think my grandfather and big brother look very good." Now Han Qing was already able to tease Chu Yuan with a calm mind.

Chu Yuan hated him so much, this little girl never said a good word about him since she knew him, but he couldn't deal with a child, and he was always blocked by her into an internal injury. The more Han Qing didn't say good things about him, the more he was cheaply trying to please her, and now he was about to turn into a two-skinned face.

Chu Yuan walked to the window and raised his hand to pinch Han Qing's little face, "You little girl, you are angry with me, why don't you admit that your brother Junyue is also good-looking?" ”

Han Qing pouted and rubbed his face, "Where is someone who asks others to say that he is good-looking?" Besides, you pinch me 800 times a day, why should I say that you are good-looking? ”

Chu Yuan found out, this little girl is not only not afraid of his identity as a prince, but also doesn't even treat him as an adult. But he didn't know why, he just liked Han Qing to treat him so casually, he felt fresh and comfortable, and he always felt happy in his heart. It's not like I'm really cheap.

Chu Yuan himself didn't even notice that the corners of his mouth were already high, "You mean to say that I was originally good-looking, but because I always pinch you, you don't want me to be proud?" ”

Han Qing was so teased by Chu Yuan's flirting skills that he could unfold at any time, his face was inexplicably hot, and he rubbed his face fiercely in order to cover it up and said, "Where are you so good-looking, you can't even compare to a single hair of my eldest brother!" ”

"You just have a hard mouth." Chu Yuan returned again, leaving behind the words that had no weight, his heart was so sour, how could this little girl look at Xie Yi who was stronger than him. looked at Xie Yi again, his eyes were full of murderous energy. Xie Yi was inexplicable, how could the prince have been sunny and rainy for a while in the past two days.

The group walked around the Taihu Lake water system, and recently the old lady also gave Han Qing some calculation work, so that he would not really have nothing to do every day.

On this day, the ship docked to replenish supplies, and Shoushan and the mother-in-law who cooked brought a few locally bought desserts. "Old lady, the weather is cold, the slave just saw that there are ginger candy red beans and bean flowers on the shore, warm your stomach with the young master and girl."

Several people stopped what they were doing and each picked up a bowl to eat, the tofu flowers were very smooth, and the red beans were sweet and glutinous, Han Qing was very happy to eat. Chu Yuan frowned and said, "I'm still used to eating salty bean flowers." This ginger candy tastes too greasy. ”

Xie Yi said with a smile: "Junyue is the taste of the north, and we are used to eating sweet bean curd in the south." Not only that, but it is customary to use brine to make tofu in the north, and gypsum to make tofu in the south. ”

"Oh? It turns out that the raw materials used to make tofu are also different? Chu Yuan still reluctantly tasted a few more bites.

Plaster! Han Qing's eyes widened. She knows that the cement used by modern people is mixed with gypsum. Now that they are working so hard to survey water conservancy, can't they also use cement?

"Grandfather, I don't know which book to turn a while ago said that three parts of limestone and one part of clay are finely ground, put them in the kiln for calcination, take them out and grind them finely, and finally add an appropriate amount of gypsum powder to make something called cement, which can be mixed with sand and gravel fine chips when used, and after pouring and forming, it should be sprinkled with water for half a month, and its hardness is very large. Now I think that it is not just right to build embankments and dams, if the performance is good, it is also to pave roads and build bridges. ”

Xie Heng knew that Han Qing had the ability to never forget, so he also listened carefully. Busy wrote down the formula on paper again, and said to a few people, "You can find someone to test it, if it is really suitable for making embankment materials, this raw material is easy to find." ”

So Chu Yuan sent one of his guards to deliver a letter to the prefect of Nanjing, that is, Han Qing's uncle Xie Zhan, and asked him to find a skilled craftsman to test cement.

Han Qing was also very happy, and inadvertently remembered the thing of cement, and his grandfather's hard work was not in vain. These days, Han Qing is very distressed when he looks at his grandfather's research on water conservancy without sleeping and eating, and he has secretly added some space spiritual spring water to the soup that everyone drinks, otherwise he really doesn't know if his grandfather's body can withstand it.

Xie Heng is nourished by his granddaughter's spiritual spring water, not only does he not feel tired and panicked, but he is also in good spirits every day, and he himself is a little surprised that his current physical strength is more energetic than when he was an official.

Seeing that the old man was energetic and went to write and paint, Chu Yuan sighed to Xie Yi, "The water and soil in the south really raise people, since I came to Jiangnan, I feel that my body is stronger, and my internal strength has grown a while ago." ”

Xie Yi also nodded and said, "Several of our martial arts practitioners also have this feeling, and even many of my family's old diseases have been cured without medicine." My grandmother's eye disease, you know, even the imperial doctor said that it could not be cured, but now I can see it more clearly. ”

When Han Qing heard the two of them say this, she couldn't wait to hide it, and fine sweat broke out on her forehead. In fact, it was only because Han Qing had a ghost in her heart that she felt empty-hearted, and where would others think about these strange places on her.

"Oh? I don't know what the reason is, is it really the geographical environment. My grandmother is a little difficult to see when she is old, so it would be nice if she could figure out why. You also know that the men of our old Chu family don't live long, and I am also very worried about my father's health. Chu Yuan regarded the Xie family as his own, so he didn't shy away from speaking.

Xie Yi was stunned for a moment, how to accept this, no matter how good the relationship is, Xie Yi is unwilling to discuss the current holy body with Chu Yuan. "If Junyue thinks that the water and soil in the south of the Yangtze River are good, you might as well bring some back to the old people to try."

Chu Yuan thought about it for a while, shook his head and said, "What Yizhi said is not entirely right, I came all the way from the capital, and it is said that Jiang is Jiangnan, but before I lived in your house, I didn't obviously feel energetic and my internal strength increased. ”

Xie Yi also thought about it, nodded and said, "Our Xie family has been settling in Hangzhou for hundreds of years, and it is impossible to test what the ancestors chose this piece of land based on, but it is true that the feng shui of the family is good." You can see that the trees and flowers in my house are more lush than those in other places in Hangzhou. ”

"Do you really want to let your grandmother and father come to live in your house?" Chu Yuan was also amused by his own thoughts. Xie Yi also sweated after hearing this, "Junyue don't go around talking about our family, if everyone comes here, our family will not stop living." ”

Han Qing also kept nodding in agreement when she heard this, and Chu Yuan saw the little girl who nodded like pounding garlic, and was happy again, "Then it depends on whether Ah Qing treats me well in the future." Han Qing heard Chu Yuan teasing her, and pursed her mouth again.
