The only reason Yun Zheng is reluctant to stay in Tokyo City is because he doesn't like to waste his life, this city is too prosperous and comfortable, if he stays here for too long, his ambition will be gradually worn out, and Yun Zheng thinks that he is not a strong-willed person, so he must leave, and he leaves with his whole family.

Life and ambition are the same as he doesn't want to let go.

"What are you going to do to compete with those tough young people in Qingtang? Your war elephants have been transported to the south, your Wusheng army has been divided into a mess, and your nine military marquis have become the commanders of various armies in the Great Song Dynasty, and it will be a big trouble for you to dare to call one. ”

"If not, how could I have left my whole family? I plan to become the prefect of Qinzhou, I am a civil official, not a military attaché, wouldn't it be reasonable to take office with my family? ”

Di Qing didn't listen to Yun Zheng's nonsense, and said directly: "What are you going to do to persuade Pang Ji and these people to agree to you going to Qinzhou?"

Yun Zheng rubbed his cheeks with his hand and said: "There will be a way, none of those people are stupid, they know what I am going to do, it is obviously beneficial to the Great Song Dynasty, they will not stop it, now is actually the best time, there are no real villains in the court, some are a group of people who want to do things."

If you look at Pang Ji, he is ostensibly fighting with us, but the appropriation of the Northwest Frontier Army has never been delayed, including the suspicious gunpowder that I think is already in large quantities, and he is also the first to satisfy those people. Whether it's the selection of the army, or the change of defense, they are all very professional, of course, he has no good way to do the lack of horses in our Great Song Dynasty, I plan to talk to him well, there is no war horse, our dreams are basically empty talk, and we want to catch up with those barbarians on the land of the northwest with two feet, this is simply a dream.

So. I'm going to find a suitable time to talk to him carefully, he won't necessarily stop me from leaving, and he's not a man who loses his conscience for the sake of office.

A qiē is put on the bright side to talk. I don't think it's too much of a difficult thing to do. The Shangyuan Festival has passed, and spring is coming. It's time for the Great Song Dynasty to be called, and there should be a new beginning. ”

Di Qing nodded and said: "In this case, the old man, the deputy privy envoy of the corpse vegetarian meal, should also move, just like we thought before, you go to the northwest, I will go to Hejian Mansion, in order not to let the Liao State taboo, the old man will not take up a military position here." ”

Yun Zheng gave Di Qing a smile with difficulty and said, "It will be outside." The king's order can not be accepted! ”

After saying these words, both of them seemed to let go of their worries, and lay down in the pile of fur with their limbs spread out to enjoy the warm winter sun, but one looked like a tiger and the other like a bear......

The Great Song Dynasty has not been so quiet for a long time, after the opening of the Ya, documents came from all over the place, Zhao Zhen did not find the documents of the barbarian Koubian who gave him a headache, the Liao people fought in the grass valley, and the Western Xia Capture Army also seemed to have no news. More news came from the border army, but it was a good sign for the opening up of Tuntian.

If Tuntian can meet the grain needs of the border army, the financial balance of the Great Song Dynasty this year is expected to exceed one million, and it will be able to transfer its strength to harnessing the Yellow River. The Ministry of Industry has long had documents proving that the control of the Yellow River cannot rely on tinkering, and must carry out the largest management in order to achieve long-term peace and stability.

In the spring of the fourth year of Qingli, the opening pagoda of Kaifeng Kaibao Temple fell, this wooden building only stood for fifty-five years, this is the pagoda built by Emperor Taizu, I thought that it could stand for many years, but I didn't expect it. A thunderstorm made it the biggest torch in Kaifeng City.

The fall of Kaibao Pagoda also opened the beginning of the disaster during the Qingli period. From that year on, endless disasters befell the people of the Great Song Dynasty. It was not until after the rebellion of Nong Zhigao that the rebuilding of the Kaibao Pagoda was put on the agenda by the ministers, because everyone believed that the thunder and fire attacked the Kaibao Pagoda and defeated the national fortunes of the Great Song Dynasty.

Although Zhao Zhen didn't believe it, but in order to comfort the people of the world, he had to rebuild the pagoda in Tokyo in the first year of Huangyou, but this time he did not build a wooden tower, but rebuilt a brick and stone tower in the upper temple with bricks and stones, after a few years of wind and rain, the tower became black, like an iron tower, so his original name was gradually forgotten, and people began to call him the iron tower!

Zhao Zhen is now standing on the iron tower, he doesn't need to look down, he just needs to look down to see the white sails on the Yellow River, and they all say that Kaifeng people have a basin of water on top of their heads, this sentence is too plain, it should be said that Tokyo people have a deadly noose hanging on their heads.

Since ancient times, the river has always been a great achievement, Haiyan River is the common dream of all emperors after the river becomes turbid, at this time of year, Zhao Zhen will come here to see the Yellow River, because at this time of the year, it is the time when the river opens, and the boiling Yellow River carries a large amount of ice from the upstream to the downstream.

The terrain of Tokyo is flat, and the ice will accumulate when it arrives, and if too much ice melts down at one time, and the ice downstream has not yet melted, an ice dam will be built in the river, which will eventually cause a subversive effect.

The river has never been a peace of mind, and it is not always possible to block it like this, and one day the sediment will raise the riverbed, and when the downstream terrain is higher than the upstream, it is when the Yellow River collapses.

Zhao Zhen himself knows this problem, and the ministers also know that everyone is waiting for the day when the Yellow River embankment collapses, but they don't know when and how that day will come, and this kind of waiting for death is simply maddening.

Zhao Zhen is looking at the Yellow River, Mr. Peng Li is taking Yun Er and Su Shi Su Zhe They are also looking at the river, the most important thing for the Yunsu family is war horses, so the old man is in a carriage, three young people are riding horses, and there are seven or eight fierce generals behind.

Such a crowd is a noble at a glance, the crowd coming and going on the wide Yellow River embankment will naturally avoid, and think that these nobles are idle to see the scenery, at this time the weeping willows on both sides of the Yellow River have not yet spit green, what can you see?

Every time they walk a hundred zhang, there will be a family who will go down to the river and fill a jar with a jar of Yellow River water, Yun Er and Su Shi will make a good sign, and then carefully put it on the ox cart behind, there are already more than a dozen such jars on the ox cart, it seems that they have been walking on the embankment for a long time.

The old man was a little lacking in energy, Mr. Peng Li fell asleep unconsciously, and when he woke up, he found that the carriage had stopped, and he was wrapped in thick fur, and he didn't know how long he had slept this night.

Outside the carriage, the sound of a young man discussing came in, and the voice was very low, as if he was afraid of disturbing himself.

"I just weighed these jars, and the most upstream jar of water is heavier than the bottom and downstream jars, that is to say, after a jar of muddy water has traveled 30 miles, the sediment is less than one or two or three dollars, and the sediment is all silted up on this section of the riverbed, if we calculate the flow of the Yellow River, it is easy to find out how much sediment is silting up every year, and we can also calculate when the Yellow River will completely burst its banks."

"That's right, as long as the speed of siltation is faster than the speed at which people raise the embankment, the Yellow River will definitely burst."

"Not only that, but you also have to calculate the speed of the riverbed, the higher the downstream riverbed, the slower the flow rate of the river, and the faster the speed of sediment accumulation, which is a variable reaction, which cannot be simply calculated with a constant quantity, and the value must be progressive."

"Knowing the day of the disaster is not a skill, and being able to come up with a way to control the Yellow River is the real skill."

"My eldest brother said that in fact, the best way is to divert the Yellow River, rather than letting the Yellow River choose its own diversion, it is better for us to choose a way out for him first, so as to minimize the loss, but I always feel that this method will not work, we will not be able to build a direct channel to the sea for the Yellow River in a few years."

"The eldest brother said that the people who governed the Yellow River in the Great Song Dynasty were actually fools, and Dayu's father in ancient times was as stupid.

In fact, the control of the Yellow River is not to make the Yellow River wider, but to make it narrower, only after narrowing, the speed of the water flow will be accelerated, once the water flow becomes faster, the water flow will automatically cut down the riverbed, the turbulent river water will continue to carry sediment In this way, the river level will become lower and lower, is it not to solve the problem of the riverbed constantly rising? ”

Mr. Peng Li saw that the three disciples were discussing very enthusiastically, so he poked his head out of the window and smiled; "It's still simple to think, in the eighth year of Qingli, the Yellow River broke in Shanghu Si in Lanzhou, so it was diverted to the northwest, through the east of the Huang River in Henan, the west of the great name of Hebei, between the Fuyang River and the South Canal, along the east of Nangong, the west of Zaoqiang and Wuyi, the east of Xian County, to Qingxian into the Yuhe, through the boundary river into the sea.

You only think about solving the troubles in Tokyo, why don't you want to think about the hardships of the people of the Daimyofu? Governing the river was never a single thing, he was almost the embodiment of the will of the entire empire.

Where it should be diverted, where it should be heightened, and even where it should be abandoned, it needs to be very clearly demonstrated, and the emperor who makes the decision probably also needs to have a very strong control wrist, otherwise the civil uprising is imminent. ”

Su Shi said with a smile; "I am the one who governs the river, and there are other people who rule the people, it has nothing to do with it, I am only responsible for building yì, as for whether it can be done or not, it is none of my business!"

Mr. Peng Li knocked on Su Shi's head with a ring ruler and said, "Bastard! (To be continued)
