Liu Hou implemented the imperial examination system, firstly, to break the monopoly of the family on government affairs, and secondly, it was also a means to collect talents from all over the country. Back then, Li Shimin said: "All the talents in the world are in my ranks." It can be seen that as soon as this imperial examination system comes out, all the scholars in the world will be wiped out by the emperor.

Of course, in order to achieve these two goals quickly, it is still necessary to supplement the promotion of free education, so that the poor also have the opportunity to study, so that they have the opportunity to change their fate through reading, so as to squeeze the people of the family out of the court as soon as possible.

As for the system of three provinces and six ministries, it is a set of well-organized central bureaucracy in ancient Chinese feudal society, and this official system is conducive to strengthening the centralization of power. Although there are many reasons, such as the Yellow Turban Rebellion, the dictatorship of eunuchs, land concentration, etc., can be taken out to make a big fuss, but there is one point that is often overlooked.

The reason for this is that the power of the local officials is too great, and the central government's control over the local areas is too weak. Many local officials are in charge of military and political power, and when they want to rebel, they want food and soldiers.

Moreover, some political regimes and official positions are hereditary, and there are many things where sons inherit their father's business and younger brothers inherit their brothers' business, and these places seem to have become independent small kingdoms, and they don't listen to the words of the central government at all. Sun Jian died, and his territory was inherited by his son Sun Ce, who died and his younger brother Sun Quan took over the baton.

Such things abound, but everyone took it for granted, so the world was naturally in chaos. Therefore, strengthening the control of the local government and the army, separating the military and the government, and strengthening the centralization of power are what every emperor in later generations has been trying to do.

The imperial examination system and the three-province six-ministry system are the systems that have developed to the extreme in feudal society, and after thousands of years of testing, they have proved to be relatively perfect systems, so Liu Hou is not polite and uses them. It is believed that these two systems can advance the process of social development for hundreds of years.

As for why he didn't use the more advanced system in later generations, Liu Hou also considered a lot. In later generations, the Celestial Empire had dozens of ministries and commissions, directly subordinate agencies and state bureaus, and with so many institutions, it was very difficult for them to memorize their names, not to mention their functional divisions.

In order to facilitate his own management, he felt that it would be better to set up only six ministries, and as for the functions corresponding to the dozens of ministries and commissions, directly subordinate agencies, and state bureaus, in fact, they could all be classified into these six ministries.

For example, the Ministry of Education and the Ministry of Science and Technology can be classified into the Ministry of Rites, and the Ministry of Railways, the Ministry of Water Resources, and the Ministry of Housing and Urban-Rural Development can be classified under the Ministry of Industry.

These affairs can be very complicated, but for the emperor, it doesn't matter how many functions you have, anyway, as soon as you encounter something, just ask the Shangshu of that ministry to ask, and as for which squire or chief Shangshu will find when he goes back, it is his business.

In fact, this is similar to the establishment of the three-three system in the army, it is very difficult for one person to manage many people, if an emperor or a prime minister is faced with dozens or even hundreds of ministries and commissions, directly subordinate agencies and state bureaus at the same time, it is simply a management disaster.

But now that the complexity is simplified, the emperor and the prime minister only need to face six ministries, which is much simpler, and this is the benefit of layer-by-layer management.

Liu Hou quickly told Chen Qun about the idea of the imperial examination system and the six-ministry system of three provinces and asked him to improve it. In fact, Liu Hou does not have a deep understanding of these two systems, and many things are just concepts.

But that's enough, what kind of character is Chen Qun? He is a great man who can create systems and laws on his own, his intelligence is absolutely outstanding, and his wisdom is also very far-reaching.

As long as Liu Hou starts, he can immediately think of the subtlety of this matter, and quickly improve the relevant system in his mind. Liu Hou just wanted to use his talent, and he really didn't disappoint Liu Hou, and soon formulated these two systems.

However, these two systems cannot be implemented yet, because the state of Wu has not yet been destroyed, and it is still the time to fight the world, and it is still the time to "unite all the forces that can be united".

The introduction of these two systems will definitely touch the interests of the big families, and if they do something, it will not be good for them to affect the process of unifying the world. After all, in the court of Shu Han now, there are still many people from big families, Zhuge Liang, Sima Yi, Deng Zhi, Ma Liang, etc., all of whom are members of big families.

These people have a very important position in the court, and if they oppose it with all their might, then the court will be in chaos, and the war to destroy Wu will definitely be interfered with, or even die abruptly.

In fact, Cao Pi accepted Chen Qun's proposal at the beginning, and the implementation of the nine-product Zhongzheng system was also out of consideration for compromise with the family. At that time, Cao Cao implemented the policy of "meritocracy", and issued several recruitment orders, as long as it was a talent, regardless of background or conduct, all of them were given heavy responsibilities, which in itself violated the interests of the family.

Some of the official positions that were originally regarded as a meal on the plate and a bag by the big families were divided by the poor. Chen Qun's nine-product Zhongzheng system, the first thing to be examined is the background, which makes those high-ranking lords have the opportunity to occupy more places.

Therefore, the Jiupin Zhongzheng system is actually the result of Cao Pi's compromise with the family, and now it is Liu Hou's turn, he also has to compromise, and the result of his compromise is to suspend the implementation of the new system until the world is unified, so Chen Qun is only secretly improving and studying these two new systems, and he does not dare to announce them.

Speaking of the war to destroy Wu, it is said that the Han army's water and land troops, under the leadership of the three fathers and sons of the Guan family, marched together and marched towards Eastern Wu. Within a day, the troops arrived at the place where Soochow had set up the "Iron Lock Hengjiang".

The so-called "iron lock across the river" is not just a chain on the river, but a three-dimensional blocking project that extends from the surface of the river to the bottom of the river. After this period of painstaking management of the Soochow Naval Army, this project has become increasingly large.

In fact, on the surface of the river, the various obstacles built by iron cables are not much of a problem, and the most fatal thing is the reef under the water surface. The Dongwu people used some dilapidated boats filled with stones and sandbags, and when they arrived at the designated position on the river, they scuttled it and let it sink to the bottom of the river to form ~ artificial reefs.

Of course, the Yangtze River is bottomless, the river is wide, and the water flow is not slow, so it is not easy to build artificial reefs in the river. In the past few years, they have recruited about 300,000 people to build this "Maginot Line", and the amount of work is about the same as building an imperial tomb.
