Although the situation in Shaanxi is generally calm, but in Shanxi, Henan, Shandong, Huguang and Sichuan, because of the famine in different ways, the people are struggling on the death line, and the imperial court does not have so much silver relief, and the number of displaced people has increased on a large scale.

After Yang Tingshu became the governor of Shanxi, he wrote several letters, complaining bitterly, but he did not expect the situation to be so chaotic.

The situation in Liaodong is even more complicated, Huang Taiji's power is completely stable, and he personally led a large army to conquer the Chahar tribe, the leader of the Chahar tribe, Lin Dan Khan, is also the co-owner of all the tribes in Mongolia, the descendants of Genghis Khan, because of the attack of Huang Taiji, forced to flee to the west, Chongzhen died of illness on the way to flee in the seventh year, Lin Dan Khan's son Ezhe, Chongzhen surrendered to Huang Taiji in eight years, Huang Taiji conquered the Chahar tribe through this, and obtained the jade seal of the Yuan Dynasty, plus the Horqin tribe that has already been submitted, etc., Huang Taiji has unified Monan, and since then, the threat to the west of Houjin has been lifted, and Huang Taiji can concentrate on attacking the Ming Dynasty.

When Huang Taiji inherited the throne of Houjin Khan, he also faced the situation of internal and external troubles, ** Hachi left behind the pattern of the eight major Baylors governing the country, Huang Taiji did not have a lot of real power, he and Daishan Amin Mang Gurtai three Baylor according to the monthly score, take turns to govern, and the other three Baylor everywhere restrain Huang Taiji, which is also the origin of the four Baylors of the Houjin.

After all, Huang Taiji is not an ordinary person, and will not tolerate this situation of a group of dragons without a leader, after a period of preparation, he did it, Chongzhen three years, Huang Taiji excused the opportunity of the two Belle Amin to abandon the four cities of Luanzhou and Yongping Zunhua to defeat back to Shenyang, and made a big fuss, imprisoned Amin, and deprived him of all the people, slaves and property to which he belonged.

In the fourth year of Chongzhen, Sanbeile Mang Gurtai and Huang Taiji had a fierce dispute, Mang Gurtai was angry, and even prepared to draw a knife, Huang Taiji would not give up, and quickly dismissed the identity of Mang Gurtai Sanbeile, and reduced it to an ordinary Heshuo Belle, and then also deprived Mang Gurtai of the identity of the blue flag owner, and Huang Taiji was in charge.

Seeing that the situation was not right, Da Beile Daishan retreated bravely, expressed his submission to Huang Taiji, and offered to abolish the reversal of taking turns in power, saying that Huang Taiji was the Great Khan of Houjin, and after handing over power, he was able to preserve himself.

After Huang Taiji completely took control of the power, he immediately began to ease and adjust the relations between the Manchus and Hans, basically stabilizing the Han people in Liaodong and the Later Jin, so that his power was further consolidated.

Since then, a powerful Houjin has inevitably stood in Liaodong.

Zheng Xunrui knows very well what the consequences will be under such circumstances, and he knows even more that with Shaanxi alone, there is no way to change the whole situation, if the Ming Dynasty cannot be stabilized, it will collapse sooner or later.

On the one hand, the existing tax system should be changed, and the tax on commerce and trade should be greatly increased so that the treasury can be filled, the second is to reduce the burden on the peasants and allow them to recuperate, and the third is to mobilize grain from the south and carry out large-scale relief and assistance to the north.

It is a pity that such a situation is impossible, whether it is the Donglin Party or the Zhejiang Party, it will not harm its own interests, it is to protect the interests of the scholars and merchants in the south, after all, it is their own interests.

Don't think about what you can't do for the time being.

Zheng Xunrui has already given Zheng Jinhong the truth, that is, to eliminate a qiē interference and develop his own strength, this own strength is Zheng Jiajun.

Zheng Jiajun developed from the Zheng family's nursing home, which was originally the eight hundred nursing homes of Hongjiabao, after Zheng Xunrui became the prefect of Yan'an Prefecture, he surrounded and suppressed the Liukou and continuously strengthened the strength of the Zheng family's army, after five years, to Chongzhen's eight years, the Zheng family army has grown to 40,000 people, becoming a force that no one dares to underestimate.

The Zheng family army has 40,000 war horses, and it can be said that the 40,000 Zheng family army are all cavalry.

However, the expenses of such a huge Zheng Jiajun are also astronomical, and the annual expenditure of silver exceeds two million taels.

The imperial court did not give Zheng Jiajun a penny of silver, so there is no need for Zheng Xunrui to report the number of sergeants of Zheng Jiajun to the Ministry of War, so far, in the materials of the Ministry of War, the total number of Zheng Jiajun is only 5,600 people, which is also the strength of the guard, which has to be said to be a joke.

Zheng Jiajun wants to keep it completely secret, it is also impossible, some people in the court know that the power of Zheng Jiajun is huge, as for how many sergeants Zheng Jiajun has, only very few people know, no one dares to calculate Zheng Jiajun at such a critical juncture, after all, Zheng Jiajun has stabilized the situation in Shaanxi, you must know that Shaanxi has stabilized, and the imperial court can be said to have basically stabilized the situation in the west.

Zheng Xunrui's development path is actually very clear, that is, the road of the feudal town during the Tang Dynasty.

However, in today's situation, it is not very likely to become a feudal town, after all, times are different.

Therefore, Zheng Xunrui is still relatively cautious, and many matters of Zheng Jiajun are basically confidential.

The research and development of firearms has become a lingering problem for Zheng Xunrui.

In order to be able to raise enough money and grain, Zheng Xunrui has traded with many Mongolian tribes, with the Ordos tribe in the north, and with the Tumut tribe and the Turpan tribe in the west, and through the guò market, earning a lot of money, and using this money to buy and store a large amount of grain in Nanzhili to ensure the supply of grain and grass for the Zheng family's army.

It is also through these mutual markets, so that the Mongolian tribes in Mobei and Moxi are basically stable, and there is no large-scale famine and chaos, and it also makes the Emperor Taiji of the Later Jin Dynasty, after conquering the Monan grassland tribe, unable to further conquer the Mobei and Moxi grassland tribes.

Huang Taiji conquered the Monan grassland tribes, so that the Ming Dynasty's Jizhou Xuanfu and Datong were all exposed to the power of the Houjin Tartars, who could bypass the Shanhaiguan and attack the Guannei, and such an attack was very sudden.

However, there is no problem with Ningxia Wei and Shaanxi Xingdu Si in Yulin border towns in Shaanxi, these places are facing grassland tribes, and they are all grassland tribes that have launched exchanges with Zheng Xunrui, and they will never attack Guannei.

This also shows that Shaanxi will not fall into the war for the time being, as long as it can stabilize the people, there will not be much of a problem, as for the Houjin Tartars, they will not attack to the west, their attention is all in the North Zhili and Shandong area.

Zheng Xunrui still has a certain amount of time to develop, but it can't be too long.

The exchange of markets and the extermination of the Liukou, Zheng Jiajun obtained a large amount of money, which was enough to maintain Zheng Jiajun's expenses, but the money earned could not be completely used for Zheng Jiajun, and it was necessary to stabilize the situation in Shaanxi.

This made Zheng Xunrui a little stretched.

The development of firearms is a must, Nanjing household right attendant Bi Maokang has invented the self-generated firearm, that is, the flintlock pistol, but the imperial court does not have the input of silver, it can not be large-scale production, and the cost of the flintlock pistol is too high, and there are still a lot of deficiencies in itself, whether it is from the bullet's muzzle velocity, ballistic range, etc., it needs to be improved, and the biggest problem with its storage is that it takes a lot of force to pull the trigger, which is not conducive to the sergeant's aiming.

However, this qiē problem is not very difficult to solve, as long as Zheng Xunrui can get Bi Maokang and Tang Ruowang and others to jointly develop it, I believe that the flintlock pistol can be improved in a short period of time, so that a large number of people can be put into battle.

The second is artillery, which is a must, and the most important feature of modern warfare is that there is specialized artillery, and the power and role of artillery are enough to change the course of war.

The power of the Furlong Machine and the Hongyi Cannon is already very good, but it still needs to be improved, for example, the Hongyi Cannon, it is best to be able to use the Blossom Cannonball, which can increase the power several times, enough to become a terrifying weapon for opponents.

Zheng Jiajun will definitely set up a special artillery battalion to separate the artillery battalion from the middle of the Shenji battalion, and I believe that after a few years, it will completely replace the battle of cold weapons.

If you want to do this, you need money and talent.

This is all a headache for Zheng Xunrui.

Bi Maokang is the right servant of the household department in Nanjing, although he is in the idle position, but the grade is not low, if you want to come to Shaanxi, you also need to carefully strategize, Tang Ruowang's Qin Tianjian in the capital, currently also belongs to the talents of the imperial court, if you want to come to Shaanxi, it is not a simple matter, and the research and development of firearms, you need to have a lot of equipment.

Zheng Xunrui needs to have the opportunity, to be specific, that is, to be able to make great achievements, so as to make a request to the imperial court, in which case, the emperor and the imperial court will allow him to put forward conditions.

At present, this qiē opportunity is all on Liukou.

But the preliminary preparations must be carried out.

The Zheng Jiajun military camp outside the city of Xi'an has been expanded fourfold and divided into two parts, the camp where the Zheng Jiajun is stationed is a part, and a large piece of space is vacated here, which is reserved for the artillery battalion to be established, and there is also a large camp, which is five miles away from the camp of the stationed sergeants, in a mountain col, the construction is basically completed, and here is the prepared firearms battalion, which is specially used to produce and test firearms.

Zheng Jiajun invested a lot of money in this regard, and even Zheng Jinhong felt strange and thought that it was not necessary, but Zheng Xunrui insisted on doing so, and he had to do it well.

As for the equipment needed to manufacture firearms, Zheng Xunrui has no plans to purchase them, both Nanzhili and Beizhili have ordnance bureaus, and there are ready-made equipment in them, and he just needs to find a way to move these equipment to Xi'an and let it play a real role.
