Xia Guo's current industrial technology system is in a very serious state of pulling out seedlings and promoting growth.

Even if there has been decades of continuous accumulation before, and a preliminary industrial development system has been formed, there is a great deviation in the intervention of Xia Guo in the process of social civilization development, and the development of all walks of life is very unbalanced.

For example, in industrial production, military industry, and shipbuilding, under Wang Ze's intervention, almost the scientific and technological level of Europe in the early 18th and 19th centuries has been reached, but there are still great deviations in the development of other industries, so Wang Ze is very worried.

After handing over almost all government affairs to the Government Council headed by Feng Jing to assist Wang Zhen in handling them, Wang Ze fully devoted his energy to the work of improving the overall civilization of the Xia Kingdom.

This time he was not too ambitious to study the internal combustion engine, telegraph and the like, although Xia Guo had already begun to distill coal to obtain kerosene, distilled oil to obtain gasoline and diesel, and the rough study of petrochemistry was already going on.

The focus of Wang Ze's research is on the upgrading of the overall industry of the Xia Kingdom, including agricultural ecology, social ethics, etc., and a very important point is how to continue to protect the current superior ecological environment in the imminent explosion of large-scale industrial production.

Based on the importance of environmental protection in Xia for decades, even though Xia has more than 40 million citizens and nearly 10 million people in its dependent countries, whether it is the East China Sea Islands that have been developed and built for decades, or the current Xia country itself and the Nanyang Islands, they still maintain an excellent natural environment.

In particular, the vast black soil of the Xia Kingdom, which took more than 300 million years to form in later generations due to various policy reasons and people's short-sightedness, was almost lost in just a few decades under the uncontrolled reclamation and destruction.

But now there is no such situation in the Xia Kingdom, except that there is very little land that has been reclaimed in the Xia Kingdom, it is because the Xia Kingdom has implemented a large number of land protection, agriculture and animal husbandry at the same time, so that these fertile black soil can continue to obtain the maintenance of organic matter, so that the thick black soil can be preserved and precipitated.

Wang Ze's research is not just invested in the laboratory like a scientist, at present, the professionalism of talents in various industries in Xia Guo has already surpassed Wang Ze himself, and he has no say in more detailed research.

It's just that Wang Ze is a time-traveler with more than a thousand years of experience after all, so he can make some guidance in many aspects.

Sometimes a scientific research is just a lack of a research direction, or just a layer of window paper, then Wang Ze's guidance is very important, and under his efforts, the various industries in Xia Kingdom have once again burst into a rapid development momentum.

Even Wang Ze sometimes pulls Lu Han, who is already the Heavenly Master of the Heavenly Daoist Academy of the Haotian God Sect, and others to discuss with them how religion can form an effective combination with society and science, further promote the development of society, and how to ensure the harmonious coexistence of man and nature in such an environment.

The Haotian Cult of God must become a factor that promotes the progress of social sciences in the Xia Kingdom, rather than restricting the development of science and technology like Catholicism, which is Wang Ze's definition of the Haotian Cult.

Although man is the spirit of all things, this does not mean that man can unscrupulously take from nature! All things are in solidarity, and the cycle of heaven is the right way! Lu Han, who was already gray, also suggested to Wang Ze in the opposite way.

After Wang Ze pondered for a long time, soon the Xia Kingdom once again began to encourage the evacuation of the people from counties with large populations, and encouraged the people of these places to move to other counties with smaller populations.

Of course, this population is calculated according to the carrying capacity of the local environment, for example, the fertile land around Zhenhai in Xia will inevitably carry more population than Longxi, the Western Regions and other places with poor environment, even if the local population in the Western Regions is less, but because of the weak environmental carrying capacity, his population density must be more than ten times lower than that of Zhenhai.

Although there are some people who are reluctant to leave their hometowns where they have lived for more than ten years, these people are a minority after all, and the Xia government strictly controls the amount of land reclamation in each county, and once it exceeds this amount, it is resolutely not allowed to reclaim wasteland.

If these people are not willing to leave their original counties, then they can only engage in landless industries such as industry and commerce in the local area, so in addition to the people in the counties and towns of the major counties, farmers and herders in the countryside are willing to move to other sparsely populated counties to obtain more land.

This great migration of people also brought another good effect, that is, it brought great changes to the current national agricultural and animal husbandry structure of the Xia Kingdom.

The original proportion of agriculture and animal husbandry in the Xia Kingdom was very large, followed by fishery and forestry, but after adjustment, a large number of people in the Xia Kingdom began to migrate to the Western Regions and Hezhong places, and these herdsmen began to fight on a large scale after arriving in the local area.

Some new characteristic agriculture and animal husbandry began to appear on a large scale, such as Gaochang because it is suitable for growing cotton and grapes, so two crops were planted here on a large scale, and even more far-sighted Xia merchants opened large-scale winemaking workshops here.

Reindeer farming around the North Sea, as well as fur farming further north, have also developed on a larger scale, and even Xia merchants have begun to transport some animal skins hunted by Xia immigrants from Penglai Island (North America) to the mainland.

Compared with the development of characteristic agriculture, although the planting area of grain crops in Xia has become smaller, it is mainly because a lot of cultivated land in the Hexi Corridor and Hetao and Lingwu has been restored into grassland and woodland, especially in Henan in the Hetao area, which has become forest and grassland.

In later generations, this grassland has been completely desertified into the Mu Us Desert, at this time, because the damage is not serious enough, it is still verdant, and there are even large forests and lakes in some places, Wang Ze hopes that this land of Yanhuang origin can continue to be maintained.

In order to protect the environment of this Loess Plateau from deterioration, he plans to keep only no more than 100,000 herders here in the future, and to carry out small-scale animal husbandry production and farming under the condition that the local environment will not be damaged.

In addition to agriculture and animal husbandry, today's Xia Guo not only has hundreds of disciplines on the original basis, but also studies the latest marine breeding work because of the continuous progress of agricultural technology in the Agricultural College.

According to the intelligence, the Nanyang Agricultural College has been cooperating with the Nanyang Commercial Company to study the cultivation technology of saltwater pearls in Luhan and Zhuya County, Nanyang, and I heard that they have begun to succeed in some examples.

Although the first few batches of cultured pearls were still relatively low in success and of slightly inferior quality, they were bound to become more fruitful over time.

In the Xia Kingdom, the scholars of the Agricultural College are actually staunch environmentalists, in their opinion, the better the natural environment, the more stable the agricultural production will be, which coincides with the Haotian God Sect of the unity of heaven and man, so it is common to see some Taoist priests who come to help in the Agricultural College.

Time passed little by little in Wang Ze's busyness, of course, in this process, he couldn't forget to pay attention to the movements of the Great Sui Empire, especially the movements of Yang Guang, Emperor Yang of the Sui Dynasty.

After all, Yang Guang is also a very capable emperor in history, even if the current Sui Empire is already weak after the defeat, but Wang Ze knows that the foundation of the Sui Empire is still there, and of course he will not underestimate Yang Guang because he defeated Yang Jian.

Fortunately, Wang Ze had made a special plan for Yang Guang as early as when he was just born, so even if he was busy every day, he had a clear understanding of every decision, every action and secret news of Yang Guang.

In order to maintain the rule of the Sui Empire, he almost completely abandoned the military aristocracy of Xianbei in Tailong, and instead vigorously promoted and reused the Kwantung Shi clan, and encouraged the children of the royal family to marry with the Kwantung Shi clan.

Although these Kwantung clans are so proud that they can't even look down on the Sui royal family, they are still very happy that Yang Guang has fallen to them, and in order to confront the Guanlong Xianbei military aristocratic group, the Kwantung clan group also has a very strong support for Yang Guang.

They not only vigorously assisted Yang Guang in stabilizing the states and counties in the Kwantung region, but even sent a large number of children and servants from their families to join the army, and Yang Guang was able to re-recruit a million troops so quickly, largely because of the help of these Kwantung clans.

The most interesting thing is that Yang Guang soon after ascending the throne under the pretext of food shortage in Guanzhong, led hundreds of officials, palace concubines and more than 100,000 troops to be stationed in the eastern capital Luoyang.

Originally, there were only more than 300,000 Sui troops in Guanzhong, which was very important to the Sui Empire, against the Xia armies in the west and north, but the eastern capital Luoyang actually gathered hundreds of thousands of troops, and the other Sui armies were also in Taiyuan, Weijun (Yecheng) and other places.

For Yang Guang's behavior, Wang Ze was almost indulgent in the past few years, allowing Yang Guang to use means to gradually stabilize the originally stormy Sui Empire, and in the first year or two after his accession to the throne, Yang Guang successively quelled the rebellions in the north and south of the river and Shuzhong.

Then he began to send a large army to quell the rebellion in Jianghuai and even south of the Yangtze River, but this time the results were not very ideal, although the Xia State did not attack the Sui Empire again in these years, but did not cancel the support for those rebel forces.

Although the Sui army crossed Jiangnan from Wuchang County to the south and successively defeated many rebel forces in Jiangnan, because of the support of the Xia State for these forces, the rebels' combat effectiveness was not weak, and most of the Sui army were new recruits who had just joined the army, so the casualties of the Zheng Sui army in a series of battles were very large.

Yang Guang was particularly angry about this situation, but in order to maintain the stability of the empire, he could only barely endure it, and under the attack of the Sui army regardless of casualties, the rebellions in various parts of Jiangnan took the initiative to surrender or hide, and in any case, the Sui Empire reluctantly restored its rule over Jiangnan.

Jiangnan was restored, but Lingnan was no longer the Lingnan of the Sui Empire.

Feng An, who had controlled the Lingnan Feng clan in the past few years, was constrained by Feng Huo after the death of Mrs. Xian, but after going to the Xia Kingdom in person, he finally decided to fully throw himself into the Xia Kingdom, not only because of the strong combat effectiveness that the Xia Kingdom had shown before, but also because the Feng family recognized the inevitable end of the fall of the Sui Empire.

Knowing that Lingnan had been controlled by Xia Guo, Yang Guang was almost angry to death, and he barely suppressed this sullen breath, but the hatred for Xia Guo in his heart was getting stronger and stronger, and even Yang Jian's death and the humiliation he suffered were recorded on Xia Guo's head.
