"Su Lian?"

When Ye Yu heard this name, he glanced sideways at Su Quanzhong, and then asked softly, "Uncle, is this someone from your Su family?" ”

"Uh, distant cousin ......" Su Quanzhong didn't expect Ye Yu to suddenly ask this question, so he answered a little hastily, because he didn't know what Ye Yu meant by this.

"Uncle, this is really a virtuous person!"

As soon as he heard this, Su Quanzhong suddenly understood, so he hurriedly said: "Virtuous nephew, this is not the old man's nepotism, but because Su Lian does have some ability to build a house......

"This little nephew naturally knows!"

Ye Yu looked around and looked at the orderly construction site, which was enough to see that Su Lian in front of him did have some skills. Moreover, Ye Yu also believed that in this matter, Su Quanzhong would not let a layman come to the construction.

Nepotism is actually reasonable, this Ye Yu can understand.

Glancing at the frightened Su Lian, Ye Yu then asked in a screwed voice: "Does this construction period really take half a year?" ”

"Returning to my lord, if it is an ordinary college building, the villain can complete it in three months, but the drawings you have drawn are not according to common sense, and all aspects must be meticulous, so ......"

Su Yu's embarrassed explanation made Ye Yu's brows furrow slightly: "Can't it be faster?" ”

"My lord, the villain said that half a year is still beautiful, if you encounter rain and snow......"

Ye Yu nodded thoughtfully, the weather is cold in this winter, and the progress of the construction period is relatively slow, and if there are a few more rains and snows, the construction period will be slowed down even more.

Then Ye Yu didn't say anything, but walked to the construction site on foot, and Su Quanzhong and Su Jian followed behind him.

During this period, Ye Yu saw that the masons were building the walls with green bricks, and the adhesive used was lime, so he asked: "This has always been the building of houses, and the adhesive used is lime?" ”

"Exactly, lime mortar is much stronger than mud as a binder, and the houses in the general farm yard are ...... with mud."

"That being said, this lime mortar is not the best choice, so why not use cement?"

Ye Yu also grew up in a rural orphanage since he was a child, and he is very familiar with burning red bricks, building houses, painting walls, and building the ground with cement in his rural hometown. So at this moment, he was in a hurry to build the academy, so he asked such a question.

However, when Su Quanzhong and Su Jian heard this, they were immediately at a loss. Su Quanzhong was better, after all, he didn't know much about architecture, he was just puzzled by what Ye Yu said.

For Su Lian, the foreman of Shentong Construction, he was completely ignorant, and immediately said with shame: "My lord, please forgive the villain for being ignorant, what is this cement......

"Literally, isn't it the finished product of mud?" Su Quanzhong analyzed the literal meaning, believing that cement is an upgraded version of the mud binder.

Seeing that the two people in front of him were at a loss, Ye Yu suddenly understood that there was any cement at this time.

Then he awkwardly organized his language, and then explained: "This cement is actually made of limestone and clay......

Ye Yu's explanation gave the two of them a preliminary understanding, and Su Jian said to himself with emotion: "No wonder adults say that the adhesion of this cement is better than lime mortar, it turns out that it is made by firing lime slurry and mud!" ”

"Since the virtuous nephew understands this method, why not ......"

Su Quanzhong's meaning is actually very clear, he hopes that Ye Yu can burn this kind of cement, not only to deal with the current situation, but also to become a best-selling product in the future.

Looking at Su Quanzhong's eyes with hidden joy, Ye Yu knew that Su Quanzhong was making a fortune again.

However, if the wall is built with cement, it is naturally much cleaner than lime mortar, and even in rainy and snowy weather, there will be no collapse due to irrigation.

He Ye Yu didn't have the ability to burn high-strength cement, but he still had some experience in the method of making cement from soil. Since in this case, facing Sheng Yi Fist, then he Ye Yu can only give it a try.

However, this attempt broke the original architectural culture of ancient China. Decades later, the entire world of architecture has entered another era.

Although the fired cement is very poor, far from the high-strength cement of later generations, this has been shocked by Su Lian's masonry.

When Ye Yu left the construction site, Su Lian looked at the direction where the carriage was leaving, and said to himself: "Third uncle, is Lord Ye really Wenqu Xing?" How can he ...... anything?"

"The capable, the omnipotent!" Su Quanzhong pondered for a long time before finally saying these words silently.

Before leaving, he did not forget to sternly remind Su Lian: "With this cement, you must do your best to complete the construction." But you have to keep in mind that you must really pass the quality test, and you must not play with your cleverness, otherwise something big will happen, and no one will be able to protect you! ”

"Yes! Even if you don't sleep, your nephew will finish it in four months! ”

……

The construction of the academy was in full swing, and the proposal of printing and papermaking made Ye Yu once again the focus of the literati of the Great Song Dynasty.

The impact of these two technological improvements is immeasurable, at least in the future, books will no longer be expensive, and the paper required will gradually become more popular.

The impact on people who read all over the world is actually far more far-reaching than what Ye Yu wrote at the beginning.

At the same time, regarding the control of this technology, Zhao Yan handed over the matter to Ye Yu to deal with, and asked Ye Yu to develop high-grade paper in the shortest possible time, so as to prepare for printing money in the future and replace the old money banknotes on the market that are difficult to distinguish between authenticity and authenticity.

Originally, the printing and issuance of Huizi banknotes were presided over by Qian Duanli, the head of the household department, but now because Ye Yu can develop a new type of paper, this matter is completed by Ye Yu and Qian Duanli.

Due to the Shaoxing counterfeit currency case, it is now involved in the improvement of the currency system. Ye Yu really wanted to take this opportunity to turn the improvement of the currency system into a reform.

In fact, at present, Huizi money is only circulated in developed state capital areas, like some remote places that cannot be implemented by the imperial court, and copper coins are still used as transportation currency.

The current Huizi banknotes, also known as the Southeast Huizi, are actually these banknotes that circulate in the southeast region, and cannot be circulated in other places at all. For example, in Huguang and other places, as well as in the southwestern states of Sichuan and Shu, the money used was issued by other institutions.

Therefore, the Huizi banknotes issued by the imperial court are not the current unified circulating banknotes. In fact, these huizi are a kind of bills, and they have not yet evolved into the kind of coins with universal value that later generations.

And Ye Yu wants to take this opportunity to unify the current currency system of the Great Song Dynasty, which is an immeasurable benefit to the life of the people and the development of commerce in the Great Song Dynasty.

At that time, Qin Shi Huang unified the whole country and unified the coins of the seven countries, which avoided the cumbersome commercial exchanges.

Nowadays, with the prosperity and development of commerce, although the five-baht coin is still a unified currency, it is too clumsy and heavy after all, and the banknote banknote was born at this time.

If paper money can be unified and national credit can be established, it will definitely be a move to benefit the people in the future.

He Ye Yu may not be able to do the widespread issuance of people's coins in later generations, but at least he can do it like the silver tickets of the Qing Dynasty to penetrate the world.

In fact, the current Huizi banknotes are the prototype of the silver bills of the later Qing Dynasty!

In the blink of an eye, it was Layue, and a heavy snow made the entire capital Lin'an like a silver dress. This year's winter snow is not very cold, but has a feeling of early spring.

As the New Year approached, the two ports in Quanzhou and Guangzhou on the coast attracted two teams of guests from afar.

The two groups of guests who came from afar were the Goryeo delegation headed by the prince of Goryeo, Wang Qi, and the other was the Japanese mission headed by Taira Kiyomori.

Ping Qingsheng, very legendary, is now an envoy to the Song Kingdom as a monk, and the legal name is Jinghai.

Although the Song Dynasty was weak, it was still a behemoth to Goryeo and Japan. At least at sea, at the moment, it is the strongest naval army in the world.

This time, the two countries sent envoys to the Great Song Dynasty at the same time, which was a rare grand event in the Song Dynasty. Since the Western Liao, Western Xia, and Jin Kingdoms came to the Song Dynasty, there has never been such a lively scene.

In fact, if you want to talk about the grand occasion of all countries coming to the dynasty, the Song Dynasty really accepted more countries than the Tang Dynasty. However, these are all countries that came from the sea, and few historians recognize this.

Goryeo and Japan have always maintained good friendly relations with the Great Song Dynasty. After all, in their eyes, the Song Dynasty was still a wealthy Celestial Empire.

The ideological reasons for this feeling in Japan are deep-rooted, because they are far away from the Central Plains continent and do not know much about Western Liao, Jin and even Western Xia.

Because for Japan's projectile land, the hinterland of the Central Plains is too big. Maybe after they landed, they could only see the prosperity of the Song Dynasty, and as for whether there were strong enemies around the Song Dynasty, they were not too enthusiastic.

Compared with Japan's blindness, Goryeo was much more sober, because they were connected to the mainland, with the powerful military of the Jin State in the west and the Mongolian nomads slowly waking up in the north.

Therefore, many things are afraid of comparison, as long as this comparison, the Song Dynasty in the eyes of the Goryeo Dynasty, although it is a behemoth that dare not touch, but also has its own position and understanding.

The two delegations came to the capital Lin'an, which was a happy thing for the people of the Great Song Dynasty. Because foreign envoys can come to worship, at least it shows that their country is still strong.

Therefore, compared with the depression when the Xia, Liao, and Jin kingdoms came to the Song Dynasty, the arrival of these two missions filled the people with a festive atmosphere.

Different feelings, different moods, it will eventually be a different feast!

At this time, Ye Yu was already busy, not only to deal with the official affairs of the ministry, but also to participate in the reform planning of the currency system, and to plan many trivial matters after the completion of the academy after the dynasty.

However, there was one thing that made Ye Yu's tired heart feel a little comforted......
