In February of the tenth year of Chongzhen, the crown prince Zhu Cihong, who had been on the throne for less than a month, took the initiative to set the throne for his younger brother, and the year name was still the eternal calendar set by Xia Nan, and he became an ordinary prince, and he did not step out of the range of Ciqing Palace within a radius of one mile in his life. Yang Sichang and Wu Sangui were beheaded on charges of "pretentiousness" and unauthorized cruelty to their colleagues, helping Zhu Cihong to take the crime, and 20,000 Guanning iron cavalry were incorporated and merged with the cavalry of Shandong to form an elite cavalry of about 30,000 people.

Zu Dashou, the spokesman of the Liaodong warlord group, received an order from the capital to let him enter the capital to face the saint, and "promoted" to the governor of the five armies, the governor of the left, and at the same time assisted the Jingying Rongzheng. In the past, this routine of "releasing military power with a glass of wine" would never let Zu Dashou take the bait, but when the news of Wu Sangui's beheading came back, coupled with the announcement that the Qiong Navy was about to go north to Ningyuan for "exercises", in the face of heavy pressure, Zu Dashou finally gave up his military power under the coercion and inducement of the secret envoy sent by Xia Nan and went to the capital to retire. The candidate to succeed the commander-in-chief of Liaodong and the general of the Liao expedition was Murong Longcheng, who had made great achievements in southern Liaoning, that is, the former commander of the Qiong Marine Corps. He was succeeded by Deputy Borhu.

After the Yongli Emperor succeeded to the unification, he issued a holy decree to build the "Conquest of the Great General's Palace" in the capital, stipulating that the national military and major political decisions must be implemented through the decisions of the generals. After the first year of the Emori calendar, the Great Shogun's Mansion became the de facto center of power in the Ming Dynasty, similar to the shogunate in Japan. Xia Nan seized power through this "peaceful evolution" method, but it did not cause much backlash across the country.

The Qiong Navy became a direct subordinate force of the General's Office, moved the garrison to Tianjin Wei, and continued to expand to 80,000 men, and maintained a reserve force of nearly 50,000 men. Since the General's Office decided to hand over all future foreign wars to the Qiong Navy, the armies of several major border towns, except for the Guanning Army, which was reorganized in the manner of the Qiong Navy, all the other border towns have cleaned up their troops, eliminated redundant personnel, reduced the number of empty salaries, reduced the size of the army, and allocated food and salaries according to the facts, thus reducing the financial burden of the central government to a certain extent.

Because of the submission of the Dutch East India Company and the decline of Spanish power, there was no strong opponent in the southern sea frontier, and the navy only maintained a standing fleet in Qiongzhou to guard the South China Sea gate, and the rest of the warships were transferred to the Bohai Bay, with the expanded marines, with Arthur Pass and Phi Dao as the stronghold, and Denglai as the rear base, grasped the control of the Liaonan Peninsula and maintained the pressure on the Manchu Qing. In the face of the "nails" in southern Liaoning that could threaten the hinterland of the rear, as well as the more aggressive Guanning army after the reorganization, Huang Taiji did not dare to act rashly, and did not dare to launch a large-scale military attack in the next two or three years, and several tentative attacks on the Ningjin defense line and southern Liaoning were easily defused. Gone are the old phenomenon of bypassing the Great Wall and entering a no-man's land in the interior.

After curbing the southward movement of the Manchu Qing Dynasty, Xia Nan freed up his hands to clean up the domestic situation. After the expansion, the Second Army and the Third Army, totaling more than 50,000 people, advanced to the northwest, while the First Army remained in Beizhili as a garrison to guard the capital. Hong Chengchou, the governor of the five provinces, became the chief adviser to the suppression of the Kou, responsible for dispatching the original officers and soldiers to assist the Qiong Navy in the battle.

In order to support the military operations of the whole country, Zhu Dadian, who had made great contributions to the development of Taiwan, was transferred back and appointed as the governor of Liangjiang, responsible for the military and political affairs of the entire Jiangnan region and Jiangxi and Henan, and was also in charge of grain and salaries and the salt administration of the two Huai provinces. Those who followed him back to the interior also had more than 10,000 tunding trained in Taiwan's reclamation. The instruction Zhu Dadian received was to clear the rich land in the south of the Yangtze River, solve the financial problems at the end of the Ming Dynasty once and for all, and achieve equal enlistment.

The vigorous Qingzhang Yintian was fully spread, violating the interests of many nobles, gentry, and eunuchs, and the resistance between the open and the secret emerged in endlessly. The nobles of the clan openly resisted the Qingzhang, and the officials and gentry secretly bribed the clerks, hid the surplus grain, and communicated in series, shouting the slogan of "not accepting grain rice and the imperial court", in an attempt to exert pressure on the entire Jiangnan to refuse to pay the grain tax, so that the Qingzhang had a miscarriage.

The general's response was to mobilize hundreds of thousands of stone of grain from Taiwan and Qiongzhou to ship into Beijing by sea to make up for the deficit of Jiangnan's failure to pay the grain levy in a timely manner, and issued a strong message that "Ningyuan will not levy a grain of rice in Jiangnan, but will also clear it to the end". With such confidence, Zhu Dadian, under the instruction of Xia Nan, carried out the "most severe blow in history" to the privileged class in Jiangnan. The nobles who participated in the boycott were ordered by the Yongli Emperor to be demoted to concubines, or were stripped of Zonglu; All officials involved are dismissed; The gentry raided the family property and "locked it up to punish the crime".

The iron-fisted policy allowed the Qingzhang Yintian to proceed smoothly, more successfully than the reforms of Zhang Juzheng's time, and according to the newly compiled fish scale atlas, the new acres of land in the Jiangnan region reached 30,000 mu (300 million mu), and the Ming Dynasty's overstretched tax embarrassment was solved overnight.

With ample food and salary as support, the military operation in the northwest went exceptionally well. In the face of the Qiong Navy, which had defeated two "Chuang Wang", whether it was Zhang Xianzhong, Luo Rucai or Lao Huihui, the big and small rogue forces all fled from the wind and did not dare to fight head-on. The strategy formulated by the General's Office was to "take the camp step by step", and every time a place was laid, it would build a tun fort, collect the displaced people and resume farming, and at the same time use militarized means to manage the displaced people, forming a tunding similar to the guard. This not only prevented the displaced people from being coerced again because they did not have enough to eat, but also strengthened the local defense. Even if the rogues kill the rifle and return to the army, they will not be able to take advantage of the armed tunding, and they will soon be attacked by the regular army who heard the news.

In the face of such a strategy, the space of the Liukou was compressed step by step, and finally at the beginning of the third year of Yongli, all the well-known leaders were wiped out, and the remaining sporadic forces chose Zhao'an, and the problems that plagued the Ming Dynasty for more than ten years were resolved.

After the success of the "internal security", the "external security" has also entered the substantive stage. The General's Mansion mobilized 80,000 Qiong Navy, 50,000 reserve troops, more than 200,000 officers and soldiers after the reorganization of the Suppression of Kou and elite soldiers from the Nine Sides, and gathered the strength of the whole country to officially open the prelude to the Northern Expedition.

After advancing all the way through Shanhaiguan and defeating several partial divisions of the Manchu Qing Dynasty, Huang Taiji led the elite of the Eight Banners, plus more than 300,000 servant armies such as Mongolia and Korea, to fight a decisive battle with the Northern Expeditionary Army. The decisive battle took place in a delicate setting, the Daling River, the site of the turning battle that brought the Ming Dynasty to its demise.

The army invested by both sides plus auxiliary troops such as baggage has exceeded one million, and the total number of large and small artillery pieces has exceeded 2,000, reaching the peak of the number of artillery used in ancient warfare - of course, most of the artillery is in the hands of the Qiong Navy, due to the fall of the "Sanshun King", the Manchu Qing Dynasty did not obtain a relatively complete cannon casting technology like another time and space, and the proportion of artillery equipped is low, and most of them are captured or imitated shoddy goods.

The Northern Expeditionary Army had an overwhelming advantage of firearms troops, and the advanced combat methods were far superior to the traditional Ming army and the Manchu army based on cavalry and infantry warfare, plus a considerable number of cavalry troops to assist, with both firepower and mobility, after a few days of fierce fighting, it paid the price of nearly 20,000 casualties, annihilated more than 100,000 elites of the Manchu Dynasty, and forced Huang Taiji to lead the Manchu nobles to flee back to Shengjing in a hurry, and achieved a decisive victory.

As the supreme coach, Xia Nan was not satisfied with such a record, but continued to go north and directly hit Shengjing City. Thousands of artillery pieces began to bombard day and night, and the powerful mortars made the Manchus even more anxious.

The contradictions of the Manchu ruling class erupted under the pressure of the strong enemy, and the banner lords, who were originally dissatisfied with the strength of Huang Taiji, began to fight among themselves, and the choice of war or peace divided the nobles into two factions. Under internal and external troubles, Huang Taiji's body collapsed, he was seriously ill, and died on the sickbed on the fifteenth day of the siege of the army. Dorgon was appointed as a temporary leader.

After suffocating discussions, the Manchu rulers finally chose to sue for peace, and agreed to the humiliating conditions put forward by Xia Nan: 1. Surrender to the Ming Dynasty, and the territory of the Manchu Qing Dynasty will return to the territory of the Ming Dynasty, 2. Disarm the bannermen, including hunting tools, iron tools must be uniformly registered and recorded, and those who conceal weapons will be guilty of felony and joint sitting; 3. Every year, young women who are in good health are screened to move into the customs, and each flag outside the customs is recorded, and only one person in each household is qualified to marry a wife, regardless of how many brothers there are.

This alternative version of the Ding reduction policy reduced the population of the Manchu Qing Dynasty year by year, coupled with strict iron control, after three or five years, the threat to the Ming Dynasty was completely lost, and since then there has been no external trouble.

Xia Nan relied on the General's Mansion to grasp power, making the emperor a puppet completely, and he did not become an emperor for the rest of his life. At the age of sixty, he passed the position of general to his eldest son Xia Hua, and since then he has created the Ming version of the shogunate era.
