- If the Pearl River water system is compared to a long dragon, then the Nanbeipan River and the Hongshui River are the dragon's feet and tails. The foot of the net dragon is the north and south pan rivers, which converge into the tail of the dragon at the mouth of the three rivers - the Hongshui River.

They first went down the Nanpan River, which was steep, rapid, and shallow, and could not be navigated by slightly larger boats. In order to solve these problems, Shen Kuo proposed to set up 'steep gates' in places where the water flow is rapid or the canal water is shallow...... By dividing the channel into sections, installing a gate and opening the gate between the two sections, the water level of the two sections can rise and fall to the same level, making it easier for ships to navigate.

Shen Kuo is worthy of being a scientific genius who only comes out once in a thousand years, and although Chen Ke coincides with him, he cannot use his self-created mathematical methods such as 'gap accumulation' and 'huiyuan' to accurately calculate the data necessary for the project such as river topography and horizontal height.

Although Chen Ke has more than a thousand years of knowledge than Shen Kuo, and when he was in school in the past, he was still a top student in mathematics, physics and chemistry, and it took him a long time to understand that the so-called 'gap accumulation technique' was the summation method of second-order differential series. On the other hand, 'Circumference' is a method of finding the string and arc length of the bow knowing the diameter of the circle and the height of the bow.

It took hundreds of years for Europeans to master this method, and in China, it is unprecedented!

No one knows how this guy figured it out. However, Chen Ke is no longer amazed, because in the past six months of cooperation, he has long been accustomed to seeing any technical problems, and he has always solved them in front of this demon. And the difference between this guy and the world is that others rely on experience to solve problems, but he relies on mathematics and logic!

And this guy is so wide and sensational. He has a deep interest in astronomy, geography, mathematics, physics, chemistry, geology, meteorology, geography, agriculture and medicine...... Considering that he is only twenty-six years old, you can see how terrifying this guy is.

If you want to ask who is the first genius in the Great Song Dynasty, Chen Ke must choose this guy, not his own uncle. He even thought for a while that the other party was a traverser like himself. And it's a doctor of science crossing. even made several tentative remarks, which made Shen Kuo confused - he was an authentic Song Dynasty person.

Well, I have to admit it. Some people are geniuses, geniuses who only come out once a thousand years. What reason do you think Chen Ke has for not protecting him? Of course, there is another terrifying science expert, Su Song......

From the first day of their arrival at the barracks. Chen Ke announced that they enjoyed the highest standard of guards, second only to Dashuai Fan Zhen, and higher than themselves, as for the treatment. Many people, including themselves, don't understand why the dignified Song champion, the deputy commander of the tens of thousands of troops, would attach so much importance to these two inconspicuous officials?

Su Song is more understanding, although he is a loose official. But after all, it is a museum job, and it is unknown how it will soar in the future. As for Shen Kuo, it's really puzzling...... You know, this thing is not even a jinshi, he relied on his father's grace to enter the officialdom.

But this is a world of imperial examinations, and the jinshi in the officialdom is king. Even if Confucius is not a Kodi. No one admits that he has real talent and real learning. Those second-generation officials who rely on grace to enter the government are the same goods who are despised and excluded.

If my father is in a high position or Yu Yin is still there, I am afraid that Shen Kuo will be like this, and my father's death tea will be cold, then my grandmother will not hurt and my uncle will not love it. No matter how conscientious and outstanding his political achievements are, his boss will turn a blind eye. There is only one time. The boss will see him, that is, something has happened to someone to take the tank......

Speaking of these years, Shen Kuo is really a bitter tear, and he can't do it for ten days. This time when he received the order to go south to join the army, he naturally thought that it was another drudgery that the non-commissioned officers were unwilling to accept, and finally fell on him. Shen Kuo secretly called him unlucky, but the military order was like a mountain, and he didn't dare to disobey the three of his dares.

I had to say goodbye to my wife and children, arrange the future, and go south with a gloomy heart, who knew that when I came to the barracks, I got such a high-standard courtesy, how could you make Shen Kuo dare not move? …,

Although the intellectual's stinky and high level made him reluctant to express anything in person, the tasks assigned to him by Chen Ke were all overfulfilled, and even the problems that Chen Ke did not expect, he took the initiative to solve them, which already showed his attitude.

And as the days of contact became longer and longer, Shen Kuo also admired this new champion more and more.

The only thing that can be admired by scientists is another equally good scientist. Although Chen Ke is far from being a scientist, his insight beyond thousands of years can really only be appreciated by the minds of the transcendent era. For example, Su Shi admires Chen Ke's omniscience, but his romantic brain is destined not to exhaustively study the boring truth. Therefore, Chen Ke never deliberately introduced those knowledge beyond the times to Su Shi.

His knowledge is really only Shen Kuo can understand, appreciate, and accept. And Shen Kuo's discoveries and insights are also only Chen Ke can truly understand, appreciate and accept.

In any case, the conversation between the two is getting more and more extensive and deeper, often starting with everyone chatting, and gradually others can't interject, they can only listen to the two of them......

For example, Chen Ke tinkered with cement and concrete, and everyone's attention was focused on its impact on war and engineering. Shen Kuo said that with cement, people don't have to cut down a lot of trees, which is a good thing for a long time.

Everyone was puzzled and asked if cutting down trees could affect thousands of generations? Chen Ke affirmed that trees can maintain water and soil and change the climate, and said that excessive cutting of trees will lead to soil erosion, barren land, environmental degradation, and ultimately unsuitable for human habitation.

This was strongly endorsed by Shen Kuo. He told the crowd that based on the history of many parties, it can be concluded that the Loess Plateau was originally densely forested and grassy, with herds of wild deer. This situation began to deteriorate in the Qin and Han dynasties, but it did not change much, because according to the "Classic of Mountains and Seas", Baiyu Mountain 'has many pines and cypresses on the top, and many oaks and sandalwoods on the bottom'. Li Daoyuan of the Northern Wei Dynasty also recorded that there was still a 'serval of Yulin' near Yulin, which shows that the southern boundary of the grassland belt should be in the north of Huanxian and Yulin, and the south is a forest.

During the Tang and Song dynasties, the forests on the Loess Plateau decreased rapidly, and desertification was so serious that 'north of Huanqing was barren for thousands of miles'. So where is the green forest on the yellow earth? One is to build a palace, and the dynasty in the capital of Guanzhong is close to take wood from here; The second is private felling, which is used for construction and charcoal. But the most serious act of destruction is to build military fortresses, this dynasty and Western Xia have been in confrontation for a long time, and nearly 10,000 fortresses have been overhauled for decades, and every time a fortress is built, a forest will be destroyed!

If cement is promoted, the few remaining forests on the Loess Plateau can finally be preserved, and trees will be slowly replanted in the future, and the ancient forests will be restored.

Shen Kuo's ecological concept was not inspired by Chen Ke's cement. In fact, before that, he went to the imperial court and collected charcoal on a large scale as the main fuel for the people and the imperial court. He also read the phrase 'Gaonu County has grease water, combustible', and once used the Ding Wei period to personally go to the border to investigate, and found a brown liquid, the locals called it 'stone paint', 'stone grease', and used it to cook on fire, light lamps and keep warm. Shen Kuo gave the liquid a new name, petroleum...... He had long wanted to use coal and oil instead of pine wood as fuel. He said that trees should not be cut down at will, especially ancient forests, and they should not be destroyed unless necessary!

In Chen Ke's opinion, his point of view is absolutely correct, but others don't care......

Therefore, this is not the so-called period of mountains and rivers, but the loneliness of the prophets.

During the inspection of the Nanpan River and the Hongshui River, the two always had to watch the stars together on a sunny night...... This kind of behavior that makes Liu Yue'e shudder, but it has no basis, but because looking up at the starry sky here can see more clearly than in the mainland. …,

Previously, they used experiments to image small holes to show that light travels in a straight line. And use this principle to explain the causes of solar and lunar eclipses and the law of the waxing and waning of the moon's phases. In order to explain this situation to everyone, Shen Kuo also designed a simulation experiment...... Use a projectile to coat half of its surface with white powder, indicating the sunny side, the side view is like a hook, and the opposite view is perfectly round. Chen Ke, on the other hand, made a larger model and used this indoor demonstration method to show the movement of the sun, moon and stars to the public.

I heard him say that he has a sphere under his feet, the moon revolves around the earth, and the earth and earth, water, fire, and Venus revolve around the sun...... Although no one was embarrassed to laugh at Chen Ke because of his identity, everyone still expressed their attitude in a euphemistic way that praised his imagination.

Chen Ke couldn't come up with an intuitive method to make them believe it for a while, so he could only laugh at it. But Shen Kuo was very interested in his statement, thinking that this assumption could solve his long-standing doubts.

Moreover, Chen Ke gave him a kind of clairvoyant mirror, which can shorten the distance between him and the sky even more, and the conditions for stargazing are really unprecedentedly good, so that Shen Kuo does not want to waste a moment. On a starry night, he aimed his telescope at the deep and distant sky, and observed night after night, despite fatigue and cold.

Although this is just an ordinary clairvoyant mirror, it has already lifted the veil of mystery in the night sky for Shen Kuo...... He saw the 'Moon Palace' on the moon, which was actually a high mountain range and a low depression. He also discovered from the movement of the light and dark parts of the moon that the moon itself does not emit light, and that the moon's light is obtained through the sun.

He also observed the moons of Jupiter orbiting it, which preliminarily corroborated Chen's claim.

Chen Ke is so embarrassed, he has been tinkering with the telescope for almost ten years, except for dedicating it to Marshal Di, it is just to see the scenery and please the little lady, which is basically a waste. But as soon as this thing arrived in the hands of Shen Kuo, it became an artifact that revealed the secrets of the universe. Why do you say that the gap between people and people is so big?

Of course, the magnification of this clairvoyant mirror is too small, which greatly limits Shen Kuo's observation, Chen Ke promises that after returning to Beijing, he will build a large astronomical telescope for him, so that he can uncover the secret of the heavenly dome!
