Ma'am, is there someone out there?

The decaying grass is in the sky, and on the embankment of the Qinghe River, the willows are not in spring, and there are only black branches left. There are no warblers, swallows, and chirping. It is the scene of winter.

It's not the time when the green willows are like tobacco and the warblers are flying. At this time, Kong is afraid that few people will come to the Qinghe embankment to collect wind and play.Shen Qing looked around, it was very open in all directions, the boundary between the sky and the earth was faintly visible between the vast and boundless river, the cloudy sky and the mountains at the edge of the sky were reflected in the clear river.

The wind blowing from the Qing River was moist and cool, and made the corner of Shen Qing's robe swing back and forth.

The winter wind is really cold.

"Sure enough, it's just you and me." Shen Qing turned around and said to Xuan Shen, "This old man actually let me dove!" But Du Zhong wanted to invite him to the embankment of the Qinghe River where the wind and waves were turbulent, saying that he had something important to do , but Shen Qing didn't see anyone else coming for more than half an hour, and the two of them, Tutu and Xuanshen, blew the cold wind for more than half an hour.

Xuan Shen was already thin, but the harsh north wind was tormenting him, coupled with the eye-catching bandage on his right hand, he looked even thinner.How pitiful, Shen Qing thought, and involuntarily took off his robe and put it on Xuan Shen.

After letting go, I felt a little inappropriate.

"Then what, you should wear it, it's so cold." Shen Qing rubbed his hands awkwardly, and turned around.I'm really cheap, Shen Qing thought.

Xuan Shen is not very cold, his clothes are thickened, but because he is thinner, he looks thin.But Shen Qing took off his robe and put it on him, but Xuan Shen did not refuse, as if he had stolen honey in his heart.

The atmosphere froze for a while, and the two remained silent.

After finally waiting for Eucommia to come, another stick of incense passed by.

"Prefect Du, you're finally done." Shen Qing went up to meet him, his attention fell on the scholar next to Du Zhong, who was wearing a thick blue long gown with a square collar. The scholar was carrying a book bag, with a stern demeanor and an awe-inspiring appearance.

"It's Du's fault for keeping Madam waiting for a long time." Du Zhong couldn't stop apologizing.

"This is??" Shen Qing had a faint guess in his heart.

Du Zhong was overjoyed, and quickly introduced the scholar behind him. "Look at my memory, this is Li Chengming, the descendant of Li Bing whom we have been looking for."

Li Chengming bowed to Shen Qing: "The villain has seen the general's wife."

"Sir, don't be too polite!" Sure enough, as he thought, Li Bing's descendants who came from hearsay were actually found, but he didn't know whether the descendants had the talents of the predecessors, otherwise it would be useless. Shen Qing only hated himself for not knowing. water affairs.In this huge Chen Dynasty, Confucianism was only respected, and other schools were not favored, which caused all schools to wither.Craftsmen are regarded as trivial skills, and talents who study water conservancy are even rarer.

"I don't know why you invited me to meet on the embankment of the Qing River?" Shen Qing asked, Shen Qing didn't think it was useless because the north wind was bleak.

Li Chengming's voice was steady and powerful, "The matter is very urgent. Today, I want to discuss with the magistrate and his wife about building the river. Please walk along the embankment and talk to me."

As Li Chengming said, he took a half step back and let the two go first.

"Mister, please go first." Shen Qing humbly resigned.

Du Zhong was rude, he couldn't see this humility, and said: "Just walk together, what kind of courtesy are you talking about? You scholars, you are very polite." Du Zhong seemed to have forgotten that he was also a serious Jinshi in the imperial examination.

Several people walked side by side, Xuan Shen fell behind Shen Qing, and followed.

During the conversation, Shen Qing realized that the so-called descendants of Li Bing were not Li Bing's descendants.Li Bing had no children, so he accepted his disciples and passed on what he had learned to his disciples. All future generations must learn about water conservancy matters, and the best ones will be able to inherit.

After Li Bing passed on what he had learned all his life to his disciples, his disciples sorted it out and obtained a volume of water conservancy scriptures. After several generations of exploration and exploration, they added to the original foundation, and later descendants traveled all over the country to sort out the records. The hydrology of each river.Previously, this book had not been circulated in front of the world. Today, Li Chengming brought all the water conservancy classics written by the Li family and handed them over to Du Zhong.

"This book, please pass it on to the world on behalf of the villains." Li Chengming untied the book bag, picked out a thick book from it, and handed it to Du Zhong.

Du Zhong flipped through it roughly, and wrote down the hydrology of rivers in various places in detail, accompanied by pictures, which are clear, detailed and thorough.He handed the book to Shen Qing again, and said repeatedly: "Mr. Gao Yi, I will definitely complete the task entrusted by Mr. and spread this book to all parts of the country."

"Excuse me, sir, how will the Qinghe River be treated?" Shen Qing put away the book and asked.

Li Chengming stopped, pointed to the winding course of the Qinghe River, and said, "The two adults should know the current situation of the Qinghe River."

The topography of Qingzhou is high in the west and low in the east, with the west mountains rising high and reaching into the cloud peaks in the west, where the Qinghe River originates, and there are many tributaries here to join the Qinghe River, and then flow eastward from Qingzhou all the way to the Yangtze River, passing through a large area in the middle. plain.

The upstream water is fierce, washing down the sand and gravel from the West Mountain. After entering Qingzhou, the river is curved and the river is curved. In addition, the terrain has become flatter, the water flow has become slow, and the sediment has accumulated and silted up the river.In the rainy season, the water potential rises suddenly, which is prone to flooding, and in the dry season, it is prone to drought.

The embankment of the Qinghe River is getting higher and higher, and the damage caused by embankment failure is also increasing day by day.

Li Chengming squatted down, picked up a dead branch, and gestured on the ground, while others also squatted down to watch.What Li Chengming painted is the river course of Qinghe River, from Xishan to Qingzhou, forming a loop bend, the south bank is close to Dongshan, and the north bank is Xiaodongshan.Dongshan and Xiaodongshan face each other across the water, one high and one low, with an endless plain in the middle.

Li Chengming drew a straight line on Xiaodongshan, connecting the middle and lower reaches of Qinghe River.

"The Qinghe river is curved, so it must be straightened. Excavate from the middle of the river, run through Xiaodongshan, dredge an artificial river, and direct the water from the outer river to the downstream. After that, build a Feisha Weir in the middle of the inner and outer rivers. The spillway can reduce the accumulation of sediment in the inner river. Now is the dry season in winter and spring, and it is a good time to organize the people to clean up the river sediment. The experience of the ancestors, "deeply wash the beach, low for the weir" is also applicable to the treatment of Qinghe River. The rest of the matter, we will deal with it step by step later.”

Du Zhong nodded. It is not difficult to wash the sand and build the spillway. The time-consuming varies, but to penetrate Xiaodongshan, do the people need to dig it out bit by bit with their strength?

"Xiaodongshan can be exploded with gunpowder. It's just that his name is Xiaodongshan, but it's not just a small mound. It's hard to blow up with ordinary explosives." Li Chengming took a dead branch and lit Xiaodongshan.

Gunpowder, upon hearing this, Shen Qing answered: "Don't worry about the gunpowder matter. I will definitely be able to blow up Xiaodongshan."

There are still some products of modern society in Shen Qing's space, especially in the last days, some armed materials are still stored in his space, including the extremely powerful C4 plastic explosives.Compared with ancient gunpowder, it is many times more powerful.

"So, it's very good." Du Zhong said, "I'm going to recruit people to start cleaning the beach as soon as possible."

"Prior to this, it is necessary to cast horizontal iron and bury it in the center of the inland river as a mark of the excavation depth. At the same time, Xiaodongshan must be dug out, and both sides must be done at the same time. Everything must be completed before the rainy season comes." Once the rainy season comes. , the river overflows, and it is no longer possible to wash sand and dredge the river, and at the same time, the exploded Xiaodongshan will also accumulate water in a large area.

"This matter, let's do it like this." Du Zhong clasped his fists, "Thank you, sir, for your advice and suggestions for Qingzhou. The tens of thousands of people in Qingzhou and I are very grateful to you, sir."

"I don't know if you have a place to live, sir. If you don't mind, the general's residence will be waiting for you today."

"Thank you Madam for your kindness. Prefect Du has arranged a residence for me, so I won't bother Madam." Li Chengming cupped his hands.

Probably people who live in seclusion are more immortal, plus Li Chengming's inherent Confucian temperament, Shen Qing always has some obstacles when talking with him.It was almost noon, Shen Qing naturally prepared the reception banquet, and after drinking for three rounds, they had already called brothers and sisters, and then they parted ways to say goodbye.Then Li Chengming lived in the guest room of Du Zhong's house, so he naturally let him go.

Du Zhong also said with a smile: "The general's house is much more comfortable than my magistrate's house. Brother Li lives in the official's residence. I'm afraid he will have to take care of him, and he will not greet you well!"

Li Chengming said calmly: "Small people in the mountains, please don't worry about it, just a simple meal."

"Then I'll take my leave!" Shen Qing thanked and left with Xuan Shen.

"My lord, is there something wrong?" Li Chengming said to Du Zhong, Du Zhong's eyes followed Shen Qing and Xuan Shen, and did not move away for a long time.

Du Zhong turned his head and said to Li Chengming: "I just think it's a bit strange for Madam to get along with his entourage, probably Madam is more approachable."

Li Chengming arrived at the beginning, didn't feel much, and kept silent without answering.If you want to talk about feelings, it's the attendant around Madam who makes him feel very unusual.
