The second day of the winter month.

When the sky was still full of starlight, from the mansion on Xuanwu Lake to the Taiping Gate in the north of Jinling City, there were lanterns and torches everywhere.

For this demonstration, Zhu Yuan's first thought was safety.

If Lao Zhu and his entourage have a situation here, even if he is a member of the clan, he will inevitably be frustrated.

Therefore, I greeted Lao Zhu two days in advance, and it was confirmed that Hu Benwei was responsible for today's security matters.

Zhao Xu, who is still hanging under the Gong Wei Division, but is actually equivalent to Zhu Yuan's personal guard captain, has not slept all night, in addition to docking security affairs with the Tiger Benwei, he also has to patrol everywhere to avoid being infiltrated in advance of Xuanwu Lake within a radius of forty miles.

In the front garden of the lake mansion, as the main demonstration place of the plan, whether it is the mini-size Kim Sango or the standard-size Zhonghe, since the matter was decided, they have also been guarding here with their respective teams in recent days.

Especially the other day it snowed.

In order to prevent the paved track from being damaged by wind and snow, in addition to putting up a shelter, the craftsmen and servants of the mansion kept cleaning day and night to prevent the snow from melting and wetting the ground here.

As a result, when it clears, there are inevitably traces of snow in the rest of the mansion, but here it seems that it has never snowed.

As the sky gradually brightened, looking at the arrangement of the garden, even if they had not slept all night, craftsmen such as Jin Sango and Zhonghe were only more excited.

My lord said that as long as you don't go on a business trip today, in the future, high-ranking officials will be indispensable.

For the craftsmen, the high-ranking officials have never had anything to do with them in the past.

Zhu Yuan also got up earlier today.

Before Chenzheng, he had already eaten today's breakfast, and took the shoulder to the southeast courtyard of the mansion.

Looking at the sixty or seventy zhang long mini track that is set up along the artificial lake and turns back through the corridor in the middle of the lake to form a closed loop, just this itself, plus the subsequent train, even if it is in a mini state, is enough to give people a small shock.

There is then a long table, and below the long table, three wooden barrels are side by side.

On the table is a steam pump that has been assembled, and there is a physical 'ppt' that Zhu Yuan is used to using personally, all of which are covered with red silk.

Similar to the latter's 'PPT' device, there are many other places in the hospital.

It's all for this demonstration, and the women in the house made them one by one according to Zhu Yuan's prompts.

Let's talk about artificial lakes.

At present, there are a few small boats by the lake, which will be rowed to a fixed point to assist the operation of the mini steam engine boat.

This irregular artificial lake dug out according to the rockery pavilion, the east, west, north and south extension is about more than 20 zhang, six or seven acres in size, although it can not be compared with the Xuanwu Lake outside, but placed in the courtyard, in fact, it is not small.

Used as a demonstration of a mini-steam engine ship, more than enough.

After looking at the other models that were carefully prepared for testing many times in the warehouse on one side, they had been rehearsed yesterday, and without testing again, Zhu Yuan walked to the north of Xiaohu.

Here are two large pieces covered in red silk.

Standard-sized steam engines.

Time is limited, although Zhu Yuan hopes to have more insurance, in the end only two units have been completed.

However, it is quite enough.

Even if both of them are lying on their stomachs, with the previous mini demo, the effect can be achieved today. What's more, the chance of the two steam engines lying on their stomachs will not be too great.

After checking it again in person, the news came that the emperor and his entourage had entered the island from the southwest passage of the lake.

Zhu Yuan walked to the gate and waited to greet him.

It's all good time.

At the end of the day, a mighty line stopped at the door of the Pingzhang mansion.

Zhu Yuan went out and saw the salute, only to find that after Lao Zhu, only three princes came today.

There is no fourth.

Of course, not even after.

Quietly continued to look behind him.

Li Shanchang, the left minister, and two Zhongshu participated in politics, Yang Xian and Fu Xuan, which are Zhongshu Province.

Tao An, a scholar of Hanlin, is actually in charge of the authority of Shangshu Province.

In the imperial history, Cheng Zhangyi is in charge of the imperial history platform and is responsible for the supervision of hundreds of officials.

Then there are two military generals in Beijing, Deng Yu and Kang Maocai.

Deng Yu, whose title is from the first rank of the right imperial doctor, is above Zhang Yi, but he rarely interferes in supervision affairs on a daily basis, and abides by the duties of a military general.

Kang Maocai, the rank is still known from the Metropolitan Governor of the First Grade, but in the future, the main authority is the Tuntian Envoy of the Third Grade.

After that, there are the various books.

However, at present, the imperial court still only has three departments: officials, households, and rites, and the other three generals of the three products, the division of agriculture and the division of Dali, and the corresponding chief officials are all present today.

In the end, there is one more left envoy of the Tai Hospital, Sun Shouzhen.

This should be Lao Zhu's special order, which can be regarded as once again showing the importance of Tai Hospital.

Waiting for Zhu Yuan and his colleagues to greet him briefly, Lao Zhu affectionately took the hand of his baby twenty-third grandson, and on the other side also took the eldest son, smiled and walked towards the door, while saying: "According to your requirements, today you can come over, and you have to satisfy everyone." ”

Zhu Yuan was pulled by Lao Zhu, and had to speed up his pace, while saying: "I will not let my ancestors down." ”

As he spoke, he walked through the outer courtyard lined with guards, and entered the southeast garden of the mansion from the moon gate that Lao Zhu had 'crashed' into earlier.

Lao Zhu swept around, roughly understood what the track was, but laughed again: "You ...... It's still covered, it's not cool. ”

"It's like a big meal, you have to serve it one by one, uncover it one by one, and taste it little by little, so that you can feel the good taste," Zhu Yuan skillfully coped, took out the small hand held by Lao Zhu, and gestured to the row of long tables: "Ancestor, and everyone, let's start from here." ”

Come to the front.

Lao Zhu stopped Jin Sanhu and the others, who had been brewing for a long time and were still nervous and trembling when they really saw His Majesty the Emperor, knelt down, and just said, "Hurry up, don't grind." ”

Seeing this, Zhu Yuan personally stepped forward, uncovered the red silk on the long table and the 'ppt', signaled that Jin Sanhu and the others could ignite the steam engine, and turned to the demonstration card that everyone's eyes were on: "All this starts with the economics I told my ancestors. Today, though, that's not the main thing. The ancestors have agreed to publish the 'Science of Economics' for your study, and you should see it in the future, but here, we will only talk about one, 'water'! ”

Most of the people present have heard about the 'science of economics' to some extent, and they are either curious, or expectant, or ...... And like the left phase, instinctively resisting.

】

Zhu Biao, who was following Lao Zhu, was originally aiming at Jin Sanhu and a few people fiddling with the steam model, listening to Zhu Yuan say that he wanted to print the 'Science of Economics', thinking about the fact that his father had finally opened up to himself to read those recently, although it was only half, he still instinctively felt that he should not do it.

Even, Zhu Biao felt in his heart that even his brothers shouldn't see that.

Turning his gaze, he glanced at his father, and then at the young man in front of the 'ppt', Zhu Biao hesitated slightly, but still didn't say anything.

Zhu Yuan has already spoken: "The development of our Chinese civilization is closely related to the word 'water'. At that time, Qin opened the Zhengguo Canal and repaired the capital Jiangyan, making Guanzhong and Shuzhong fertile for thousands of miles, and with this accumulation, the world was unified in one fell swoop, which shows the importance of 'water'. Besides, at present, why Jiangnan is called the 'land of fish and rice' is also because of the water. However, from the perspective of the entire Chinese territory, Henan, Hebei, Shandong, Lianghuai and other plains are actually more suitable to become thousands of miles of fertile fields, but why the truth is just the opposite, the fundamental reason is still in the word 'water'. In the past few decades, the Central Plains has been either drought or flood, and the harvest has been repeated, and the world has finally collapsed. So, how to restore the Central Plains to a fertile field, the first one lies in the extensive repair of water conservancy, and the other is in sight. ”

Zhu Yuan said, Jin Sanhu and the others had already poured hot water into the mini boiler and lit the candles.

When Zhu Yuan's words fell, three mini steam pumps began to run at the same time, and the water pumped from the wooden barrel on the ground gushed out from the water outlet of the pump.

Seeing this situation, even if Zhu Yuan didn't continue, most of the people present instantly understood a lot.

The Central Plains is already the most suitable for farming, and there is no shortage of rivers.

However, what is most lacking is how to transfer the flow of water to the fields.

Traditional pumping equipment is too inefficient, and when it is really needed, it is just a drop in the bucket.

In front of them, everyone fantasized about enlarging the mini steam pump, and then placed it where it should be placed......

I couldn't help but feel strongly touched in my heart.

Future!

This...... It's really the future of the Ming Dynasty!
