Bai Tu pretended to have no ambition in front of Cao Cao, just as much as possible for the convenience of the future, and was not in much urgency, even if he directly said to Cao Cao "The heroes of the world are only Sikong and Tu'er", he couldn't fly over and hack Bai Tu to death, so he turned to confirm other things with Lu Su.

"What are the drawings of the keel waterwheel and the results of the hydrological surveys of the counties?" Bai Tu asked Lu Su about the task of the Ministry of Civil Affairs.

The digging of deep wells has come to an end, but the Ministry of Civil Affairs cannot be idle, and now it is the stage of spring ploughing, and if we can not levy and dispatch labor, we will not levy and dispatch labor, but when the drought arises and there is no land to plant, we cannot be idle.

When the drought is dry, it is also the best time to clean up the river and prevent future floods, and the white map gave the theoretical drawings of the waterwheel of the Tang Dynasty technology of the Ministry of People's Affairs, and ordered the craftsmen of the Ministry of Civil Affairs to restore and try to build it......

"The basic sample of the keel waterwheel has been realized, but it is still being simplified as much as possible, and different styles of samples are developed for different water flow environments...... The progress of the hydrological survey is not up to the demand, and there are too few grassroots officials in this area. Lu Su reported his estimates.

"Then you work hard first, and try to survey the areas with different feng shui as much as possible." Bai Tu sighed secretly.

There is still too little time, and the county school is just emerging, barely giving ordinary wealthy families the opportunity to teach Mengtong literacy...... As for the education of practical techniques such as hydrological surveys, there is still a long way off.

Lu Su's "viewing the earth" is not omnipotent, it is mainly the judgment of "feng shui".

Some small-scale climate fluctuations do not cause changes in the climate.

And used to observe hydrology and geology, the efficiency is only equivalent to that of ordinary experts in water conservancy and geology - this is still Lu Su himself has studied similar knowledge, so the effect can be achieved.

The main advantage is that you can "see the earth" on the map out of thin air, but this kind of long-distance observation will further reduce the accuracy.

And when "observing the earth", it needs to consume mental power, and Lu Su can't maintain it for too long every day.

Therefore, it is impossible for Lu Su alone to support the hydrological investigation of the entire Jiangdong.

If you want to achieve all-round potential improvement, the number of cadres and capable people at the grassroots level is very important, which is now the talent hall and the selection test, which cannot be satisfied in a short period of time, and it must also be cultivated by schools at all levels.

Even in the growing prestige of Baitu, the number of middle and low-level officials absorbed by the Naxian Pavilion is already very enviable in the eyes of other princes, and there are even top talents among them, but it still cannot replace the role of laying a solid foundation.

Now we can only give priority to the investigation of the hydrological environment of the area where Lusu feels the fluctuation of the ground atmosphere, and then give priority to the design of the river dredging and ditch excavation plan.

As for the placement and configuration of the keel waterwheel, it gives priority to the northern part of Poyang County and Wu County, corresponding to the two most fertile and flat plains in Jiangdong - the Poyang Plain and the Taihu Plain, the latter of which is called "Zhenze" in the Eastern Han Dynasty.

Theoretically, the Jiangdong region, the two plains in the east and the west, is enough to reclaim 1.5 million hectares of cultivated land under the Han system, and as long as the water conservancy equipment can keep up, it can become fertile land.

Moreover, the concentration of land is conducive to large-scale official tun and military tun, and what Bai Tu wants to master most is also these two granaries, if he can control these two plains in the hands of the state pastoral government...... Even if it is only half, coupled with the improvement of waterwheel irrigation and the increase in yield per mu, Bai Tu completely dares to pat his chest and give up the field tax of other counties in Jiangdong!

Of course, in fact, there are many difficulties, and it is easy to reclaim wasteland, but who is willing to give Baitu an easy gift of cultivated land that has already been secured?

Wu County was originally one of the two most powerful areas of the Jiangdong family, not even a family, even if it was an ordinary farmer, it was not Baitu who moved away when he said it, and Shennong couldn't do it in his second life......

In contrast, the situation in Poyang County is better, because the mountains are more and more troublesome, and the strength of its own family is weak, and the population density is also very low, a lot of wasteland is waiting for Baitu to be reclaimed, and there is already the cultivated land of the master, which can also be slowly replaced.

The benefits of large-scale tuntian are obvious, and Cao Wei's future Guantun in Huainan is the best example.

However, the reason why Cao Wei was able to be in Guantun in Huainan was because Huainan first experienced a major drought in the second and third years of Jian'an, resulting in ten rooms and nine emptiness, and then Cao Cao forcibly relocated the people of Huainan in order to guard against Sun Quan, causing a large number of Huainan people to cross the Jiangdong instead and fill the population of Jiangdong......

When Deng Ai was in Huainan Tuntian, there was a lot of barren land in this place, so there were no disputes between the government and the people caused by the property.

Bai Tu can't smash Jiangdong to a mess by himself, just to have a place to Tuntian, right?

Regarding the replacement of Wu Jun's land, Bai Tu, Yu Tuo, and Lu Kang also hinted, but even with the closeness of these two people to Bai Tu, they all used not to respond and pretended not to understand as a statement.

But Bai Tu also has his own way, he can do things that no one else can do......

For example, I heard that the Zhang clan and the Huiji Yu clan of Wujun are all big sellers of illicit salt, and "boiling the sea for salt" accounts for a large proportion of their wealth.

In this year, you can't turn your face with these big families because of selling illicit salt, after all, Bai Tu doesn't want to make it too bloody, it's just ...... It just so happens that Bai Tu recently figured out a "ditch beach salt drying method", which is not too good, and it is more than a thousand years more advanced than the current boiling salt method, with higher quality and dozens of times higher efficiency, and because it does not require fuel, it has a lower demand for the environment, and it can easily crush the existing sea salt market in Jiangdong into slag......

As for the few companies that occupy the mines and take "casting mountains for copper" as the economic pillars, Bai Tu does not need to specifically investigate their private occupation of minerals, blast furnace ironmaking, steel frying or something, Bai Tu does not want to show very much.

Bai Tu felt that as long as he was given time, these families should be very good at talking and having a win-win spirit.

"What's going on with the 'deep well disease'?" Bai Tu asked instead.

Lu Su rolled his eyes at Bai Tu's great interest - this is probably the willfulness of high reputation, Bai Tu doesn't care about this level of ridicule at all now, and he is not worried that this ridicule will turn into a civil resentment.

Instead, I was looking forward to who was going to cry after the deep well came in handy.

……

Before the first month, three hundred miles southeast of Jinling, some discordant things were happening in a village under Yangxian County.

Introduced from the Naxian Pavilion, because of his great courage, he also performed well in the bandits of Wu County before, and was promoted by Zhou Tai and Chen Gong successively, and is now Sima of the other department.

"Hahaha, you're just too polite! Okay, I know that you thank General Ben for clearing up the bandits for you, so you don't need to send it! Pan Zhang laughed.

Several village elders who were swept by his eyes also squeezed out a smile, and some of the village youths who really couldn't see it were also pulled back by light or secret.

It's not the first time Pan Zhang has done this kind of thing, and he is not the only officer who has done so, and even if it were to be changed elsewhere, the proportion would only be greater......

However, today is a little different, just when Pan Zhang was about to leave with the loot, the young man of the old Li family at the head of the village, eleven or twelve years old, usually strong-blooded, at this time, one did not take care of it, and actually rushed out to stop it, but was kicked out by a Dubo under Pan Zhang.

The Li family and his wife hurriedly stepped forward to plead, and when the sister who had not left the cabinet came out to support her younger brother, she was suddenly left behind by Pan Zhang and found out...... As far as the village girl is concerned, this girl is actually a little clear-eyed!

Du Bo Ma Zhong, another Du Bo Ma Zhong on the side, found that Pan Zhang's eyes were not right, and he wanted to step forward, so he hurriedly persuaded him: "General, it's okay, in case someone finds out......"

"Discovery? What about discovery? Who is not trying to seal his wife and son, with the credit of a certain person, but she is just a village girl...... Even if they are stabbed, General Zhou and Chen Taishou can still really compare with a certain person? Pan Zhang impatiently pushed Ma Zhong away.
