Time is objective, whereas feelings are subjective. Happy days are always short for everyone, and painful days are always long. This Spring Festival, for the Perak soldiers who face each other on the west bank of Mianshui, although the war is tense, it is also very comfortable. After all, if you are well fed and warmly dressed, you can eat meat, and you can drink sugar water mixed with wine when you are on duty in shifts, and the Spring Festival will pass in a blink of an eye. The Mongolian cavalry could eat and clothe themselves, and the Mongolian Han soldiers could also have food and clothing, and the new attached army of Yang Wen'an, which had the lowest status, could only be half-starved and half-full, and life was much more difficult. The new vassals lived in makeshift huts, leaking from the wind and the cold rain. Under the pressure of hunger and cold, the outbreak of epidemic is almost inevitable. As the epidemic spread in the new annex camp, many soldiers fell ill, and many of the sick and dead were dragged out of the camp every day.

As early as the beginning of the epidemic, the Mongol cavalry and the Mongol Han army withdrew to Yang Wen'an's department and re-encamped a few miles away. In order to prevent the spread of the disease, Yang Wenan was forced to drive the sick soldiers to the corners of the camp to fend for themselves, and even drove the sick soldiers to the river in an attempt to spread the disease to the Perak army, but before they could reach the shore, they fell under heavy artillery fire. Yang Wen'an tried to throw the dead body across the river with a heavy trebuchet, but the trebuchet was destroyed before it could be installed. What Yang Wen'an didn't know was that every move of his battalion was under the observation of the Thunderbolt Army's telescope, and his intention to lead the water to the east was naturally clear.

After the Spring Festival, seeing that the weather is getting warmer day by day, and looking at the gradually rising river, Yang Wenan has the idea of retreating. It's just that Liu Heima did not agree to withdraw from the army, and his uncle Yang Dayuan also wrote a letter to reprimand him for his lack of patience and determination. In the letter, Yang Dayuan told him ominously that after the beginning of spring, there would be a big move in the Lin'an court, and there would inevitably be chaos within the Song army, and then he could take the opportunity to raid, and even take the whole of Sichuan in one fell swoop. After receiving the letter, Yang Wenan had to strengthen the defense of the camp while sending people to the surrounding states and counties to collect food. Affected by the epidemic, the number of soldiers under his command has been reduced to 2,200, most of whom are in poor health due to lack of food, and their combat effectiveness has decreased considerably. What's worse is that the food in the camp has run out, and now it is the spring famine season, and the people still live on tree bark and wild vegetables, and there is not much food to be scavenged.

The big move of the Lin'an Imperial Court mentioned in Yang Dayuan's letter is the "planning method" launched by Jia Yidao. At present, the Song-Mongol War has been going on for nearly 20 years, the Great Song Dynasty's finances are close to collapse, and the imperial court is in an unprecedented financial crisis. To solve the financial crisis, it is necessary to start from two aspects: opening up sources and reducing expenditure. From the perspective of the country's main tax sources, Sichuan, the original tax heavyweight, has basically been destroyed, and only more than 20 states in more than 60 states are left in the wilderness, from the "country of abundance" that can deliver huge taxes to the country every year has become a bottomless pit that needs huge financial subsidies from the state; A large amount of land on the Jinghu North Road and Lianghuai (now Hubei, Anhui and southern Jiangsu) was designated as military tuns, and its income could barely sustain the needs of the local garrison.

Except for these traditional grain tax centers, there was not much tax paid to the imperial court in the rest of the place. There was not much arable land on Fujian Road, and the Fujian villagers were forced to go to the sea to make a living, and the seemingly prosperous foreign trade was basically embezzled by the Quanzhou clan and Pu Shougeng and other returning merchants, and the interests of these people were tightly entangled with the court officials, and the government actually did not collect much tax, and spent a huge amount of money every year to support thousands of clans in Quanzhou; However, Liangguang is still in a semi-primitive state of high mountains and dense forests, and the output of land is limited, and if taxes are strengthened, it will lead to popular uprisings and even rebellions. In fact, at this time, in the entire Southern Song Empire, the taxes were so heavy that the common people could no longer live, and the taxes in many places were even collected in advance until decades later.

Since there is no way to increase tax revenues, we have to find ways to reduce expenditure. Naturally, the expenses of the royal family cannot be reduced, and the salaries of officials cannot be reduced, so the only way to do so is in military spending. In the annual financial expenditure of the imperial court, military expenditure alone accounted for ninety percent. The huge military expenditures and the millions of rewards after the victory made the Southern Song Dynasty court already overwhelmed. At the same time, the military commanders and generals of the border have colluded with those in power in the DPRK to be frantically greedy for military resources, and for a long time no official in the DPRK has dared to put forward the "reality of a nuclear military brigade." In response to the crisis, Jia Yidao had no choice but to introduce the "planning method" in order to clean up military spending, in fact, he also knew that this would be opposed by a group of border commanders and generals, and it would set off a huge wave among the front-line defenders.

The so-called planning method is to recalculate the financial situation of the armed forces in an attempt to reduce the phenomenon of eating empty quotas and drinking soldiers' blood, which is also a good thing. The phenomenon of eating empty money and drinking the blood of soldiers in the Southern Song Dynasty army has been accustomed to it since the founding of the country. Even many famous generals are inevitable, such as Han Shizhong's full quota of 70,000, and the actual soldiers are only 30,000 all year round. With the passage of time, the vacancy in the army became more and more serious, even as high as nearly four-fifths, and the military expenses required for 50,000 people were allocated every year, but the actual number of troops was only 11,000; When Kuoduan attacked Sichuan, the Sichuan, Shaanxi and Song Dynasty armies were full of 100,000 troops, but in fact, only more than 20,000 people from Cao Youwen's department died in Yangping Pass, and they were all gone; For example, the Chizhou Navy has a full quota of 3,000 soldiers, and the actual number of soldiers is only 1,000, excluding the old, weak, sick and disabled, and there are less than 200 people who can go into battle.

If the "plan law" can be implemented fairly, it will definitely help enhance the combat effectiveness of the Song army, but Jia Rudao has selfish intentions and uses the "plan law" as a tool to exclude and blame those who have already been blamed. Selectively enforcing the "plan law" means leniency to one's cronies, or simply turning a blind eye to their corrupt behavior, but severely punishing those generals who have a gap with them or who are unwilling to be attached to them, or even framing them with fabricated charges. For example, the Lu family headed by Lu Wende, the envoy of the Jinghu system, was seriously corrupt, and in order to get rid of the relationship, he sent his son Lu Shikui to hand over a large amount of money to the state treasury, and his corruption was not investigated. Yu Xing, who was greedy, sent a large amount of gold and silver to Jia Yidao, but he was only punished. The above two people successfully passed the test because they were both close associates of Jia Nidao.

And those who don't like themselves or have festivals, Jia Rudao will die. For example, Xiang Shibi, Cao Shixiong, and Gao Da, these famous generals, said that the money and grain they withdrew when they resisted the invasion of the Mongol soldiers were embezzlement, and then charged them with embezzlement of official money, and the light ones were dismissed and exiled, and the serious ones were imprisoned and persecuted to death. Wang Jian became famous in Diaoyu City, and out of jealousy and jealousy, he transferred Wang Jian to an idle position; Gundam had shown disdain and ridicule for him, and he took the opportunity to send him to prison. Cao Shixiong was also exiled to death for not flattering him. Xiang Shibi, the envoy of Hunan Province and the governor of Tanzhou, was demoted to Zhangzhou and ordered him to pay for it, and finally died because of it. Even if these people are not clean, they can be regarded as disciplined people in the officialdom of the Southern Song Dynasty, where everyone is corrupt. In fact, in order to resist Mongolia, Xiang Shibi donated millions of his family wealth to fund the army. More importantly, these people are all extremely capable generals, and after they were deposed or imprisoned, most of the cronies promoted by Jia Rudao were mediocre people such as Fan Wenhu, which caused the army's combat effectiveness to plummet, which was really self-destructing the Great Wall.
