Ruyin County was governed more and more stable by Shu Yan, but earth-shaking events happened in Luoyang, the capital division.

Sima Lun, the king of Zhao, did not have the patience to disguise any longer, and directly deposed his nephew Sima Zhen and ascended the throne as the emperor himself.

Since the imbecile emperor Sima Zhen succeeded to the throne, the power of the dynasty has fallen into the hands of four people: Yang Jun, Sima Liang, Jia Nanfeng, and Sima Lun. A maternal uncle, a wife, and two uncles of the family. Although the first three were authoritarian and oppositional, none of them had the intention of rebelling, and only Sima Lun took a substantial step. The reason for this, in addition to Sima Lun's own bad nature, is also inseparable from the impetus of his traitorous conspirator Sun Xiu.

Before the incident, Sima Lun first added nine tin for himself. "Tin" through "giving". Jiuxi is the nine highest standard of glorious treatment given by the Son of Heaven to the courtiers to have the right to use, the main ones are: chariots and horses, the chariot specifically refers to the chariot and the chariot, and the horse must be a pure black stallion two horses, that is, eight horses; The Garment of the Crown; The music of Xuan hanging, the dance of the eight hundreds; Three hundred tigers and so on. These are all treatments that are exclusive to the Son of Heaven and should not be enjoyed by courtiers.

There are only a handful of people who have added Jiuxi in history, and most of them are Wang Mang, Cao Cao, Sima Yi, Sima Zhao and the like. Jiuxi is a sensitive word, once Jiuxi is added, it basically means that it is not far from rebellion. But these powerful ministers, such as Sima Yi and Sima Zhao, in order to avoid being too public, only develop their strength in secret, would rather not accept the Jiuxi special gift.

Father and brother have made great contributions, but they still dare not accept the special gift of Jiuxi, Sima Lun, a mediocre and unprestigious person, is arrogant. After the addition of Jiuxi, the government and the opposition have more criticism. Sima Lun knew that he could not convince the public, so he discussed with Sun Xiu, hypothetizing that the first emperor Sima Yi passed down the divine language, and ordered himself to replace Sima Zhen's position as the Son of Heaven and enter the palace as the emperor.

After Sima Yi's death, he was first succeeded by his eldest son, Sima Shi. Since Sima Shi had no son, he passed the throne to his second brother Sima Zhao after his death. Then there are Sima Yan and Sima Zhen, the sons and grandsons of Sima Zhao respectively, so Sima Zhao's lineage has become the authentic inheritance of the throne. Sima Lun thinks that he and his second brother Sima Zhao are the same sons of his father, and of course he can't continue to be under his line as an emperor. Since he sought to usurp the throne, he set up another temple, not to worship Sima Shi, Sima Zhao, and Sima Yan, but only to worship his father Sima Yi, ready to open his own line.

However, directly removing Sima Zhen from the throne is too blatant and unreasonable. Sun Xiu gave him an idea, and ordered his confidants to issue a Zen edict in the name of Sima Xin, which meant that Sima Zhen voluntarily gave up the throne to Sima Lun and offered the seal. Of course, Sima Lun had to pretend to be modest, and then arranged for some confidant ministers to pretend that the first emperor had a life like this, and persuaded him several times before he agreed with a twist. After ascending the throne, he immediately found an excuse to depose and kill Sima Zhen's legal heir, Sima Zang, the crown prince, and renamed his son the crown prince. Moved Sima Cheng to Kim Yong Cheng and was named Emperor Taishang. Sima Zhen is Sima Lun's nephew, and he was actually promoted to the title of Emperor Taishang, which is also extremely strange.

Sima Yi's great cause of enduring humiliation and hardship all his life fell into the hands of Sima Zhen's unbearable great-grandson. Sima Lun, as Sima Yi's own son, was able to usurp the throne, and it was precisely by taking advantage of this that he won the support of some people. However, the ancients have always been different, and the emperor's family is even more so. Even if Sima Zhen is completely unworthy of being the emperor, he should be selected from Sima Yan's other sons, and it will not be Sima Lun's turn at all. Even if Sima Yi really appeared, he would definitely follow this principle.

Sima Lun knew that his name was not right, and in order to win the hearts of the people, he had just ascended the throne and opened a big reward. Needless to say, Sun Xiu and other cronies have all sealed the big county, and they are just one king short. The officials of more than 2,000 stones, such as the county guard, were all marquis. Too many students, filial piety, and talent don't have to take the test, and they are directly selected to be officials. Those who have no officials have become officials, and those who have officials have been knighted. In this way, the number of people who add titles to officials has increased exponentially, resulting in a serious shortage of mink tails as a material for decorating official hats, and there is no way to continue with dog tails. This is where the dog-tailed marten comes from.

Although there were many officials, the treasury was so empty that it could not support so many rewards, and even the gold and silver for the inscriptions of the officials' seals were insufficient, so this unprecedented and ridiculous reward was a joke from beginning to end.

The court and government group composed of the mediocre emperor and the treacherous ministers was destined to not last long, and it was not even as popular as the stupid Sima. This rabble lasted only a hundred days before it was overthrown.

It was the other four kings of the Sima family who overthrew Sima Lun. The first to initiate the army was Sima Yin, the king of Qi. Sima Jian's father was Sima You, the former king of Qi who had a dispute with Sima Yan and Sima Zhen's father and son. After Sima You's death, Sima Jian succeeded his father to the throne.

Sima Jian raised his arms and shouted, and the other three kings, Sima Ying, the king of Chengdu, Sima Hao, the king of Hejian, and Sima Yi, the king of Changshan, immediately raised troops in response.

Sima Lun's usurpation of the throne pushed him to the forefront, and both the government and the opposition complained about him. The banner of Sima Jian's side was to re-establish the deposed Sima Zhen to return to the dynasty. In this way, all the people's hearts are on the side of Sima Jian and the other four kings. Therefore, although Sima Lun had a huge power advantage in imperial power, he was unrighteous and helpless, and was soon destroyed. Sun Xiu and others were killed. After all, it was still the face of the royal family, Sima Lun was not killed on the spot, but was confined to Jin Yongcheng. However, Kim Yong Cheng's role is equivalent to a royal death row, as long as he is sent here, it basically means that his life is short. From the Empress Dowager Yang Zhi, to the crown prince Sima Shu, to the queen Jia Nanfeng, Sima Lun could not escape this fate.

Sima Cheng was invited back from Kim Yong Cheng and re-established as emperor. The Jin family was in a coma, the government and the opposition, the ministers of civil and military affairs, either advocating empty talk, or single-mindedly for themselves, no one really cared about state affairs, and no one was loyal to the court. The success of Sima Lun's usurpation is proof of this. If the ministers all have a little bit of loyalty and a little bit of responsibility, this will not be the result at all.

At this time, the ministers collectively kowtowed to Sima Zhen and pleaded guilty. Although Sima Zhen is dissatisfied with the ministers, but the style of the government is like this, what can be done! He issued an edict to the world, rewarding and commending Sima Jian and other relevant personnel who supported the emperor anyway, and all the rebellious ministers were beheaded. Sima Lun left a whole corpse because of his royal relationship, and was given to drink poisoned wine and died.

Sima Jian was named the Great Sima because of his great merit anyway, and he supervised the Chinese and foreign military, and was even added Jiuxi to take charge of the government. The front door drives the wolf, and the back door enters the tiger. Since then, the puppet emperor Sima Zhen has fallen into the hands of a new man.

No matter how the Sima family tossed, in short, there was no change of dynasty, only limited to the chaos in Luoyang City, which had no big impact on the people in other regions.

The people of Ruyin are still living like this. It's not exactly like that. Because of the new county governance group, the entire Ruyin is quietly changing.

At the beginning of his tenure, Shu Yan lamented the hardships of the people's livelihood and secretly resolved to improve the people's living standards. The premise of improving the living standards of ordinary people is to let them have money in their hands. In the whole society, it is mainly divided into four categories: scholars, farmers, industrialists, and merchants, among which farmers are the main body of the people, scholars belong to the upper class, and industry and commerce are untouchables.

In the case of agriculture and commerce, the merchant does business, the worker does the work, and the farmer does the farming. If we only develop agriculture, it will be too narrow-minded, how can we make all the people rich? That is, agriculture and industry should communicate with each other, each performing its own business, and all of them should be active. Since agriculture is the mainstay, it must be given priority to development, and while agriculture is developed, other industries will also be brought along.

The life of the common people does not involve chariots, safaris, singing and dancing, and is just the most basic food, clothing, housing, transportation, firewood, rice, oil and salt. Among them, eating is the primary issue. If we want to solve the problem of eating, we need to increase the production of cereals. There are two ways to increase cereal production: one is to increase the yield per acre, and the other is to increase the amount of arable land.

Shu Yan started from these two aspects.

Increase yield per mu. In the case of a normal year, the yield per mu can be increased by means of superior seed fertilization, deep ploughing and fire, and intensive cultivation, but I am afraid of encountering a year when the wind and rain are not smooth. In the event of a flood or drought, no matter how intensive the cultivation is, it will be basically in vain, so try to get rid of relying on the weather for food. The most important thing is to solve the problem of irrigation. The water resources in Ruyin are quite abundant, in addition to the two main rivers, the Ru River and the Ying River, there are dozens of small rivers. It would be very beneficial if the water from these rivers were brought into the nearby fields.

In addition to increasing the yield per mu, it is also necessary to increase the number of acres of fields. Is there any uncultivated wasteland in the world? Yes, and there are quite a few of them. Compared with the many measures to increase the yield per mu, the measure to increase the number of acres of cultivated land is simple and crude, that is, to reclaim wasteland.

To reclaim wasteland, people can only rely on fire and a small pickaxe, how easy is it! First of all, it is necessary to set fire to the prairie during the withering season, which not only burns the dead grass, but also burns most of the grass seeds by the way, which greatly reduces the growth of plants and trees in the coming year. Before the freeze or in the spring of the following year, you can use a pickaxe to open up the wasteland on these burned fields. But in the wilderness, long-term unrestricted natural growth, all kinds of grass and trees have grown and hardened, and the fire only burned the dead grass stems and leaves on the ground, and the roots of the ground are still intricately and tenaciously rooted in the soil, and they are very tough. Uncultivated land is very rigid and difficult. Even if a piece of land has been cultivated with great difficulty, the amount of grass seeds buried in this land is much greater than the number of grass seeds in the perennial cultivated land, and they will breed again when the spring breeze blows. This can go on for years, and with a little inertia, the land will be turned back into an overgrown wasteland. In addition, these newly cultivated wastelands do not have a manure base that has accumulated over many years like cooked land, so the yield is very low, and they often cannot pay back for several years.

This is why the peasants would rather work as tenants for the big families than open up the land themselves.
