In addition, there is the problem of military preparations, with the pacification of the north, Jiannu temporarily lost the strength to go south and knock on the pass, in a short period of time, the north will be in a relatively stable period, so that the Great China and North Korea can free up their hands to complete the internal unification.

Moreover, before Xiao Tianjian led his troops back to Nanjing, he explained the things to Lu Xiangsheng and Luo Li and others, and Lu Xiangsheng was also working hard in the north to handle them.

When he returned to Nanjing this time, he brought a large number of former ministers back to Nanjing, and the officials supplemented the north with some officials selected by the Great and Middle Dynasties from the south, which made the old forces of the former dynasties in the north be split into a mess, and also made it impossible for the old forces of the former Ming dynasty in the north to make waves in the north.

After Lu Xiangsheng returned to the south of Xiao Tianjian, according to Lu Xiangsheng's ideas, he had already begun to act, especially about the division of the Jiannu side, which was carried out quite smoothly, and a group of captured Mongols were secretly sent back to Mobei through the Xuanda area.

Soon the Mongol tribes in Mobei began to react, after all, this time the Mongolian Eight Banners followed the Jiannu army to fight in the south, and the losses were very heavy, and the Jiannu always used the Mongols as cannon fodder, so that the Mongolian soldiers who went out with the army would suffer very big losses, but at the same time they did not get any cheap, and this time their business could be said to be a big loss.

The most important thing is that through the two battles of Tongzhou and Shanhaiguan, the Mongols also thoroughly saw the strong strength of the Dazhong army, so that they also saw the situation clearly, and knew that if they continued to follow Jiannu and fight against the Dazhong Dynasty, they had no advantage to take advantage of, and in this case, they had to reconsider the future way out.

The Mongols in Mobei are very dependent on the interior, especially for the tea, iron, and salt in the Central Plains, which are all necessary for their survival, if they can't grab them, they can only trade with the Central Plains through the mutual market, obtain these necessities for survival, and expect Jiannu to provide them with them, they don't have to think about it, Jiannu will not give them these materials at all in order to control them.

Now that Jiannu has been defeated by the Dazhong Army, the Dazhong Army has also overthrown the Ming Dynasty, fully controlled the situation in the north of the Guannei, closed all the channels for the supply of goods outside the Guan, captured and slaughtered a large number of merchants who had illegally passed through the Jiannu and the Mongols outside the Guan, completely cut off the way for the Mongols and Jiannu to obtain these goods, and also made their products unable to sell, squeezed in their hands, all kinds of materials outside the Guanxi became extremely scarce, and the war dividends were gone, so they had to find new ways of supply.

Now the Great China and the DPRK have taken the initiative to send people to contact them, expressing their willingness to treat them differently between the Mongols and the Jiannu, as long as they give up continuing to be the tiger and help the Jiannu to be the enemy of the Great and the Middle, then the Great and the Chinese and the DPRK will agree to trade with them, and they can give them a "fair" mutual market price, which is undoubtedly very attractive to the Mongolian tribes.

Moreover, now the Mongolian tribes have long been falling apart and have lost their unity, and immediately after the Dazhong Dynasty threw out this bait, some Mongolian tribes began to take the initiative to surrender to the Dazhong Dynasty, expressing their willingness to accept the conditions of the Dazhong Dynasty, and accept the management of the Dazhong Dynasty in the future.

As a result, the Mongolian tribes, which were already dissatisfied with Jiannu, immediately fell apart internally, and each other began to have internal strife in order to continue to follow the master of Jiannu in the future or switch to the arms of the Great Middle Kingdom.

However, Lu Xiangsheng followed Xiao Tianjian's intentions, and for some Mongolian tribes who expressed their willingness to take refuge in the Great Middle and Korean Dynasties, he adopted a policy of Huairou and opened up the mutual market in Xinghe outside the Xuanfu Wanquan Right Guard, and only traded with the Mongolian tribes who were willing to surrender to the Great Middle and Korean Dynasties, the Mongols will definitely gradually alienate Jiannu and resubmit to the Great Middle Dynasty in large numbers.

Moreover, the envoys sent to Korea also landed in Korea relatively smoothly under the cover of some Korean officials loyal to the Ming Dynasty, and secretly met with the Korean king Li Liang.

As a vassal state of the Ming Dynasty, the former king of North Korea must pass the approval of the Ming Dynasty before he can be regarded as the king of North Korea, but this Li Liang came to the throne through mutiny, so for the suzerain, the Ming Dynasty, it is a crime of disobedience and must not be accepted, so the Ming Dynasty refused to formally agree to canonize Li Liang as the king of Korea, which made Li Liang very dissatisfied.

Later, after the establishment of the Qing Dynasty, the Emperor Taiji sent 100,000 troops to conquer Korea, and the Korean army was unable to resist, so it had to cut off its support for the Ming Dynasty, and instead acted as a subject of the Qing Dynasty, accepting the dispatch of the Qing Dynasty, and paying tribute to the Qing Dynasty.

But when Xiao Tianjian sent an envoy to North Korea, the North Koreans knew that the Ming Dynasty had fallen, and now the Central Plains is already the master of the Great Chinese Dynasty, although some people do not quite accept this reality, but there is no way, so they can only turn to the Ming Dynasty's goodwill, transferred to the Great Middle Korea, in their eyes, who presided over the Central Plains, who is orthodox, this concept is in the hearts of the North Koreans, has been deeply rooted.

What made Li Liang even more tempted was not how much kindness he had to the Dazhong Dynasty, but when Xiao Tianjian sent the envoy, the envoys informed Li Liang that if Li Liang was no longer ordered to build slaves from now on, then he, as the emperor of the Dazhong Dynasty, could officially represent the Emperor of the Central Plains and canonize Li Liang as the king of Korea.

In addition, the Koreans were very unkind to see Jiannu, this time Jiannu would go south, forcing North Korea to send out 10,000 soldiers and horses, and more than 20,000 servants, this time almost all of them were lost outside Shanhaiguan, and the Koreans also learned the details of the two battles of Tongzhou and Shanhaiguan through the envoys of Dazhong, and saw the weakness of Jiannu.

Since Jiannu is no longer the opponent of the Great Middle Dynasty, and the Great Middle Dynasty is willing to canonize him Li Liang as the king of the Joseon Dynasty, in the future, the DPRK will still have to listen to the Central Plains regime, and the Qing Dynasty's expropriation of the DPRK is quite heavy, which makes the Koreans quite dissatisfied with this, so after meeting the envoys of the Great and Medium Dynasty, the two sides can be said to hit it off.

Even though the Korean king Yi Judang said that he was willing to accept the canonization of the Dazhong Dynasty and would no longer be a vassal to Jiannu from now on, because Li Ju first wanted the support of the Korean ministers, he would gradually stop supporting Jiannu in the future and stop providing various materials to Jiannu.

In this way, Xiao Tianjian's established goal of dividing and building slaves from the east and west has been basically achieved, laying a good foundation for the next step of the Great China and North Korea to settle the affairs of the south and Shaanxi, and then go on another northern expedition.

As for the puppet Shun regime of Li Zicheng in Shaanxi, it is needless to say that since the formation of the army of the expedition to the west, the war of the Dazhong army against the Dashun army has presented a one-sided situation, Yan Chongxi and Liu Bao led the army, and the Dashun army of Li Zicheng was full of teeth, and the Dashun army was defeated in a fight, and before the Chinese New Year, if it was not for the sudden heavy snow in Shaanxi, which affected the attack of the army of the expedition to the west, it is estimated that Yan Chongxi and others would have already hit the city of Xi'an.

But I didn't think that Li Zicheng couldn't hold on, just two days ago, Yan Chongxi sent 800 miles to report to Nanjing, Li Zicheng suddenly gave up Xi'an Mansion, and fled to Hanzhong with the remnants, they were sending Wang Chengping to pursue while the whole army rushed to Xi'an, it is estimated that now Xi'an Mansion has been controlled by the Great Chinese Army, so Li Zicheng's fall will not be too long.

Therefore, the war situation in Shaanxi is very optimistic, and everyone in Dazhong and the DPRK is happy about this, and they are only waiting for the next step to gather and annihilate Li Zicheng's main force in the area of Hanzhong Mansion.

Of course, although the Great Middle Dynasty has been busy with the war in Shaanxi in the past few months, it has not relaxed for the two small courts of the Southern Ming Dynasty in the south, and all kinds of military preparations in the early stage are in full swing, and the soldiers and horses of the fourth town have gone to the surrounding areas of Fujian one by one after the whole training, and they have formed a semi-encirclement situation in Fujian, and batches of materials have been transferred to Ganzhou and Wenzhou Prefecture, and they are hoarding materials.

Luo Rucai led the soldiers and horses of the third town, and drove into Guizhou and southern Huguang in large numbers, and began to threaten Guangxi and Yunnan.

The most important thing is that as the main force of the southward movement of Liu Yao's department, the original Second Guards Division was divided into two after following Xiao Tianjian back to Nanjing, and on the basis of the second division, the Fourth Guards Division was once again formed, and in two or three months, outside Nanjing, the new recruits were replenished and retrained, and new equipment was also replenished.

Now in the large Chinese army for a large number of flintlock pistols equipped with bayonets, the status of pikemen in the large Chinese army plummeted, the development of equipment, but also led to changes in army tactics and formation, so Xiao Tianjian in the reorganization of the second division and the fourth division, completely pikemen this class, from the two new divisions, only retained two percent of the knife players, as a melee cover force, but also as a grenadier use, a large number of knife players equipped with thunderbolts, making the two new divisions more combative, In particular, the close-range firepower output greatly exceeds the current division-level establishment of all the current Western armies, and also exceeds the proportion of musketeers in the current Western armies, making the army of the Great China and North Korea, in this era, the most powerful army in the world.

In addition, with the steady expansion of the territory of the Great Middle Kingdom, there are more and more resources that can be used, iron is no longer a scarce resource in the Great Middle Kingdom, coupled with Xiao Tianjian's efforts to develop the smelting industry in recent years, a very large-scale iron plant has been established in Huguang Metallurgical County, and large-scale iron smelting furnaces have sprung up like mushrooms after a rain, making the iron production of the Great China and North Korea more and more large, and it is faintly close to the iron production of the heyday of the Ming Dynasty.

In addition, the new type of smelting furnace is constantly being established, the molten iron of the iron-making furnace directly flows into the iron-frying furnace to fry mature iron, so that the iron output increases at the same time, the quality of iron has also been steadily improved, although Xiao Tianjian has not yet had time to preside over the research of the steel-making open hearth, but once the wisdom of China's craftsmen is mobilized, the energy is also quite huge, so through the refining of small steel-making furnaces, the Great and Middle Dynasties have been able to initially obtain better quality steel, which has become a solid backing for the Great Chinese Army.

Coupled with the popularization of the use of iron fan casting technology, over the years the iron fan casting process has been continuously improved, now under Xiao Tianjian's point, the iron fan casting process has developed to the core of the water cooling process, so that when the iron cannon is cast, the inner chamber condensation speed is accelerated, forming the self-tightening of the gun body, so that the quality of the iron cannon is better, the body of the gun is less trachoma, and the ability to withstand the pressure is also stronger.

In this way, the iron cannon can be loaded with more gunpowder, the range is longer, and the accuracy is higher, so that the cannon casting technology of the Great China and North Korea has basically caught up with the best cannon casting technology in the West in this era, especially the process of iron fan casting cannon, so that the speed and yield of the cannon casting in the Great Middle and North Korea can be proud of the world.

Coupled with the increase in steel production, the casting of steel cannons has become a reality, the characteristics of steel are destined to be cast into steel cannons, the bore wall can be thinner, and the weight of the cannon body is significantly lower than that of iron cannons of the same caliber.

Therefore, the number of cannons equipped by the Great Chinese Army is also increasing, and the iron cannons that were first cast have now begun to be eliminated and replaced with newer artillery.

The original three-pounder gun, because it is an emergency product, in addition to the gun body is relatively light, convenient for the mobile operation of the large Chinese army, but the three-pounder gun has the disadvantage of too little power, now the large Chinese and North Korea have been established, the number of mules and horses used to pull the cannon began to be sufficient, and there is no longer a need for this kind of small-caliber artillery as before, so in order to strengthen the role of artillery, the three-pounder gun has recently been stopped casting, the original battalion artillery, has been upgraded to the divisional artillery battalion, an artillery battalion with five artillery companies, which can be used centrally, It could also be supplemented with battalions as a company, so that the two new Guards divisions became experimental units.

The two divisions began to use six-pounder guns as the main force of light artillery, supplemented by a company of eight-pounder medium guns and a company of twelve-pounder guns, which made logistics and supply easier, and the firepower was much better than before.

These two guard divisions also completed the training and armament of the year ago, and in the year before that, they conducted an exercise outside the city of Nanjing, showing extremely strong combat effectiveness, and they can fight south at any time, and become the backbone of the future southward operations.
