In May, the number of things in the DPRK and China suddenly increased, and while the Ministry of Households had already stepped up its propaganda for the issuance of new currency, the officials who had been sent to various places to form banks also began to set out in batches to their respective territories, and the printed new coins were secretly distributed everywhere under the escort of the army. At the same time, when it is time to collect the summer tax, the household department will also send personnel to various places to supervise, and June is also the time for the merchants from all over the country to come to the Song Dynasty for trade, and they will also collect the commercial tax with the city shipping department.

At the same time, the next month will start to recruit new soldiers, and when the veterans are demobilized, the military department is also very busy, they have to determine the number of demobilized soldiers, cooperate with the officials and localities to resettle, and pay compensation; In addition, it is necessary to allocate recruitment targets, determine training plans, and select officers to fill vacancies. This year is the third year of entering Jiangnan, and it is a year of grinding and surveying the newly appointed Beijing officials and local officials, and they have to examine the officials in various places, and they are promoted or demoted according to their political achievements, and they are also very busy.

The Ministry of Rites is not idle, Zhao Yu's biological mother is Yu Xiurong, as usual, he should be posthumously sealed after he ascends the throne, he has not been posthumously sealed because the Empress Dowager Yang is still alive. Now after returning to the capital, the Empress Dowager Yang also felt that the emperor was growing up, and missed the old man, so she issued a decree to posthumously give her a posthumous title and a nickname. But Yu Xiurong died in the chaos of the war and was hurriedly buried in the wilderness, and some of the parties were no longer alive, they had to find a new convergence and be buried in the imperial mausoleum, and they had to negotiate before they could decide on the name.

In the end, all the things have to be concentrated on the emperor, so there are many things underneath, and Zhao Yu is very busy, he not only has to give orders from time to time, but also hold court meetings and assemblies, discuss and decide on the matters in the various ministries and newspapers, and he must understand and review them in advance. And the most important thing at the moment is of course the new currency issuance, as expected, after the start of the publicity, there have been a number of rush to buy, people have exchanged the salt tickets in their hands for the real thing, naturally most of the gold and silver and silk silk with the highest retention rate, for a time the silver building and silk shops were emptied.

Because there was a plan, the household department released part of the stored silk silk from the warehouse, and the government treasury also responded to the call to allocate materials to supplement the market, according to preliminary statistics, a total of more than 400,000 silk silk silk was put into the market. In the four major trading areas of Lin'an, Quanzhou, Guangzhou and Mingzhou, more than 30,000 taels of gold and more than 200,000 taels of silver were put into the market. When people found that the supply of materials was sufficient and prices were stable, they slowly calmed down, and the rush to buy only lasted for half a month before basically subsided, laying the foundation for the issuance of new currency.

And Zhao Yu also serves as a privy envoy, and there are many military affairs to deal with. Now that the rainy season has arrived, Mengyuan's offensive this year has also come to an end, but the threat is still there. According to the information sent from various places, the Meng Yuan had recently begun to build a large number of fortresses on the riverbank, and rebuilt the city walls of the prefectures and counties along the river that had been demolished, and it was obvious that they had realized that if the Song army crossed the river, the various units scattered along the river would not be able to resist the firearms of the Song army without the protection of the city wall, and would not even wait for the arrival of reinforcements to be annihilated.

Zhao Yu knew that this was Boyan's idea again, and he realized that the Song army was no longer the weak army it was at the beginning, and his own side was no longer an invincible force that could sweep the world, and it was no longer possible to take Jiangnan lightly as he did back then, but his own side would be threatened by the southern army from time to time. Therefore, it changed its past offensive and turned to a defensive position, hoping to establish a strong stronghold by building a large city, so that it would not be defeated by a single blow when threatened, and then calmly dispatch reinforcements to the rescue.

Some people expressed concern about this, thinking that with the establishment of the defense system in the north of the Mengyuan River, it would be more difficult for them to cross the river and make an expedition to the north, and it would be far away to recover the two Huai. But Zhao Yu did not see it that way, he saw this as a historic turning point, marking a reversal of the war situation between the Song and Mongolian sides. The decline of the Mengyuan and the re-emergence of the Great Song Dynasty is already the general trend, and they have passed the most difficult time, from the defensive to the offensive, and the success of the Northern Expedition is just around the corner......

"Subordinate Zhou Xiang, thank Your Majesty Longen!"

"What is this doing, why do you have to do this great gift!" After the meeting on this day, as soon as Zhao Yu returned to Lengquan Hall, Xiao Huangmen stepped forward to tell Zhou Xiang that he would meet Xie En. But as soon as this guy came in, he bowed three times and bowed nine times, shouted long live, jumped him down, and hurriedly asked Wang De to pick him up.

"Your Majesty, it's hard for your subordinates to express it if it's like this, so let your subordinates finish worshipping!" Zhou Xiang is a big guy, and he still insists on giving a full set of gifts. And he is obese, and Wang De can't pull it.

"You and I have been kings and ministers for many years, why bother to make these false tricks, it's good to have me in your heart, get up!" Zhao Yu waved his hand and smiled.

"Your Majesty's kindness to his subordinates is as deep as the sea, and it is difficult to repay even if you die!" Zhou Xiang raised his sleeves and wiped the corners of his eyes, and insisted on kowtowing again before standing up under Wang De's pull.

"Director Zhou...... Oh, it's time to fight, it should be called Zhou Shilang! Wang De dragged Zhou Xiang up and bowed his hand.

"The big official is so ashamed to kill the Sprinkle family, such as in the past, it is okay to call Lao Zhou and Zhou Fat!" Zhou Xiang was indeed frightened, and hurriedly replied in fear.

"How dare you be a little one, this time I was promoted to the right attendant of the Ministry of Industry, and I am also a member of the third grade of the imperial court, I can't shout nonsense, otherwise I will say that I don't understand the rules!" Wang De said with a smile.

"The Sprinkle family and the officials have known each other for so many years, and they don't know how many catties and taels the Sprinkle family has, and it is all thanks to His Majesty's grace that they can have today, but it doesn't matter, who dares to talk more, Lao Zhou will go to reason with them." Zhou Xiang still looked like a fool.

"Let's talk under the porch outside, it's hot and tight here!" Zhao Hao pouted. Zhou Xiang is always running a train with his mouth full, that is talking about people and talking nonsense, but he still likes this gag guy very much, but he has solved a lot of problems for himself over the years, and I don't know how much joy it brings.

This time, Zhao Yu's promotion of Zhou Xiang to the right attendant of the Ministry of Industry was also under pressure, first of all, he was born in an ordnance workshop and had no fame; Moreover, he can only be regarded as a technician, and the temple supervisor who becomes the ordnance supervisor is basically the end, and there are few dynasties that have promoted engineering and technical personnel to high-grade government officials; In addition, it has always been in the rear and has no military merits, even if it serves the army, it is difficult to take the road of military capital.

However, the old people in the court all knew that although Zhou Xiang's official position was not high, he had made great contributions to the manufacture and renewal of military weapons, because no matter who he was, he had to read his credit. And Zhou Xiang's life is also one of the reasons for this, his appearance is ugly, it seems to be very obscene, but he is indeed very good at things, and he has always been not smiling or talking, and he is humorous.

In addition, Zhou Xiang is a warm-hearted person, who will help if he has something, the conditions in Qiongzhou are difficult, everyone can be said to be the city of Fucheng with a bare ass, and whoever starts a house will inevitably lack this and that. And he has been in charge of construction for a long time, so he used his 'position' to help Zhang Yu and sent craftsmen to help. Therefore, the officials of the DPRK and China, both old and new, remember his affection.

This time, Zhao Yu promoted Zhou Xiang exceptionally, in the name of 'great meritorious', although some people also objected, but his good popularity helped, several deacons and ministers were silent, and the opponents lost their temper, so that they were successfully promoted to the post of squire of the Ministry of Works. This incident still caused a sensation in the government and the opposition, and it is an unprecedented thing for a technical official to participate in the government and politics, and it is also an exemplary role, which shows the mind of the emperor today who is not eclectic to reduce talents, and also opens the era when non-scholars are not allowed to be officials.

"Your Majesty, how did this water reach the mountain?" Out of the house, Zhou Xiang accompanied the emperor to the pavilion, but he was soon attracted by the waterfall that flowed down the mountain, but what attracted him was not the picturesque beauty, but how he did not see how the water was sent up to the tank on the mountain. In the earliest way, in order to form this artificial waterfall, it was generally used to transport water to the mountain, or to use a winch to lift the water, and later there were windmills or waterwheels to lift water. But Zhou Xiang was amazed that he didn't see anyone carrying water up the mountain, nor did he see tall windmills or waterwheels.

"Hehe, it's really a layman watching the excitement, and an insider watching the doorway." Zhao Hao smiled when he heard this, "Some people have seen it before, saying that it is magical, but no one has asked how this is done, you are still the first." ”

"My subordinates are just stupid in the workshop, and they always want to understand when they see strange things, so this must be from Your Majesty's hand!" Zhou Xiang said.

"I saw that it was very hard to transport water to the water tank on the mountain, and it was not suitable for installing a waterwheel here, so I thought of a way to design a water lifter, and let the general make one according to the drawing, but I didn't expect it to run very smoothly, and I was thinking about promoting it on the occasion of the relocation of the ordnance superintendent, so as to improve efficiency and reduce the labor intensity of the craftsmen." Zhao Yu said and sat down in the pavilion, and instructed Xiao Huangmen, who was with him, to bring the model of the water lifter in the study.

"Your Majesty, is this what it is?" Xiao Huangmen quickly put a ruler-long cylindrical model on a few places, and Zhou Xiang looked up and down, left and right, but could not understand the mystery, and asked suspiciously.

"Bring a basin of water!" Zhao Yu asked Xiao Huangmen to carry the basin of water, he put a section of the long cylinder into the basin, and rotated the crank at the other end with his hand, and a stream of water sprayed out of the opening, and as the speed of the crank increased, the flow of water became larger.

"This ......" Zhou Xiang was stunned and pointed at this thing, stumbling and not knowing how to express his surprise.

"Don't mess around, I'll show you!" Zhao Yu glared at him and said, knowing that he had already seen many of his inventions and should have already gained immunity, but his exaggerated expression was still very useful, which could make you feel proud. And that's what it's capable of, and it's always going to find a way to make you feel comfortable.

"Hehe, please give your majesty advice!" Zhou Xiang was called by the little emperor, and he didn't feel embarrassed, but just said with a smile.

"Actually, it's very simple, there is only one screw rod in this tube, and you can use it to lift the water up by stirring the handle!" Zhao Yu disassembled the water lifter in three times and two times, and spread it on the table.

In fact, this thing is called the Archimedes spiral water lifter, which is known as the first pumping machine in history to transfer water from low to high places, which greatly saves people time and runs up and down to transport water, and also saves effort, and is a kind of machinery used for irrigation. It is believed that it was one of the many inventions and discoveries made by the ancient Greek philosopher Archimedes, and that the machine is still used in Egypt and parts of Europe to the present day.

However, recent research has shown that the auger water lifter was used as early as the seventh century B.C. during the "hanging garden" period in ancient Babylon, making it also famous. Its principle is also very simple, that is, the centrifugal force generated by mechanical rotation makes the water produce speed, and then rotates upwards with the pipe wall, and when the water rushes to the pipe wall, the pipe wall will continue to produce thrust to the water, so that the water climbs from low to high, so as to achieve the purpose of lifting the water to the highest.

"Your Majesty is really a man of God, and he can lift water to a high place with such a simple object, which is much simpler than a waterwheel." Zhou Xiang looked at each part one by one and praised it sincerely, "My subordinates think that Your Majesty has combined this water lift with the waterwheel, and used the power generated by the impact of the waterwheel to urge the spiral shaft to rotate, so that the lake water can be lifted to the trough on this peak without manpower, forming a waterfall." ”

"Well, you can draw inferences now, and you can understand the principle just by listening to my explanation!" Zhao Yu nodded and said, as he said, he used the flow of water flowing into the lake as a driving force to lift the water.

"It's a shame that my subordinates have been taught by His Majesty for many years, but they have only learned a little skin!" Zhou Xiang said with a guilty face.

"You're good!" Zhao Hao smiled and said, look at Zhou Xiangqi, who is also in his forties this year, and he also has blooming hair on his head. It is also remarkable that he can comprehend the mystery of machinery with his senses and practical operation without understanding the principle.

You must know that after so many years of development, the current ordnance supervision is also gradually transitioning to mechanization, not only with hydraulic power as the forging machine, lathe, drilling machine, planer, boring machine, etc., but also gradually with a simple wooden machinery to the transition to all-metal machinery. As a result, the precision of the processing has also been greatly improved, making the weapons manufactured more accurate and durable, and this is all organized and produced by Zhou Xiang in addition to his own 'creativity', which is transformed into practical application, and he has also been able to familiarize himself with all the equipment in the workshop in the process.

"Your Majesty praises it, where are your subordinates and what happens to Your Majesty." Zhou Xiang looked honored and disgraced at the moment, and said with a straight face, "My subordinates also implore Your Majesty to bring back the water lifter and let the craftsmen copy it for production." ”

"That's fine, but there's something clever about it, have you ever noticed?" Zhao Yu raised his hand and asked him to excuse himself.

"Can you use it upside down?" Zhou Xiang frowned when he heard this, pondered for a while, and suddenly said......
