Chongzhen three years, early February.

Wang Zezhi's team to enter King Jingqin was blocked in Xuanfu, and when Chongzhen received Wang Zezhi's plan to enter King Jingqin, he immediately issued a decree to let him garrison Xuanfu.

Xuanfu Town, one of the nine border towns established in the early Ming Dynasty, is an important town in the northwest border.

Geng Ruqi and Zhang Honggong's reinforcements were scattered, and the defense of Xuanfu was empty.

Wang Zezhi was the closest to Xuanfu, and it was most appropriate for him to be stationed in Xuanfu.

The division of the capital has already defeated the army of Huang Taiji, and there is no need for Wang Zezhi to enter the king of Jingqin.

As for the four cities of Yongping, there is no need for Wang Zezhi to worry about it, Sun Chengzong has his own arrangements.

The strategic location of the four cities of Yongping was extremely important, but Huang Taiji only left an army of 5,000 people for Amin.

5,000 men to defend these four cities is really difficult for a strong man.

The Ming Dynasty also realized the importance of the four cities of Yongping at this time, and sent a large number of Ming troops to launch a fierce attack on it.

The Ming army of 10,000 people went to the Amin army of 5,000 people, and these four cities could not be defended at all. If Huang Taiji had sent troops to rescue Amin at this time, the situation would have improved, but Huang Taiji had no intention of supporting. Then there are only two ways to go in front of Amin: first, fight to the end with the Ming army and die on the battlefield; Second, plunder, and then abandon the city and flee.

In the end, Amin chose the second path.

If so, forget it, Amin Belle slaughtered the Ming people in the four cities before leaving.

In the battle at the entrance of Huang Taiji, he issued a lot of "edicts" to the local officials and people of the Ming Dynasty to surrender, and Amin Belle's behavior made many arrangements of Huang Taiji useless, and what was waiting for him was bound to be a dead end.

What Amin did was a mistake, it was a crime to be defeated and captured, and it was a great crime to abandon the city and flee.

Huang Taiji gave Amin 5,000 troops, making it clear that he wanted Amin to make mistakes, no matter what he did, it would be a dead end.

Originally, Wang Zezhi planned to go and persuade Amin Belle to let him surrender himself for his own use.

Then he was assigned to the original Chahar Department, where the original Chahar Department was located, and fought with Huang Taiji.

At the same time, prevent him from going mad and slaughtering the people of the four cities.

God is not willing to do it, and his plan is stranded before it can be implemented.

It's not that Wang Zezhi is instigated, but he doesn't want to turn his face with Chongzhen so quickly.

You must know that there are only tens of thousands of Qinwang troops surrounding the capital now.

If he doesn't listen to his will and acts recklessly, Chongzhen turns around and deals with him first, and he will definitely die.

Amin Belle couldn't recruit him, and the people in the four cities were also dead, Wang Zezhi was like a witness to history, he could only watch and do nothing.

Wang Zezhi was not a person who was willing to do so, during the period of garrisoning Xuanfu.

Wang Zezhi summoned Ma Huai, and there is only one principal in the current Foundry Bureau, which is Ma Huai.

Ma Huai and Zhao Can cast cannons at the same time, and Zhao Can used other people's half-baked theoretical knowledge to cast cannons, which have a short range, easy to dew, explode, and a high scrap rate.

Ma Huai used his own experience to transform other people's technology, and the cannon cast had a long range, no explosion, no gas exposure, and a low scrap rate, the key is that the casting time is still short.

Up to now, Ma Huai has cast fifteen cannons, plus Li Luo's three, Wang Zezhi already has eighteen cannons in his hands.

Now six of these cannons have been arranged by Wang Zezhi on the wall of Xuanfu City.

In addition to the cannon, Ma Huai has already figured out the process of making flowering shells.

Even, he developed his own method, and the flowering cannon made with his method was not only powerful, but also would not explode in the air.

It is a more advanced drop point fried.

"My lord, you're looking for me." Ma Huai arrived and asked respectfully.

"The Foundry Bureau will stop everything and cast cannons with all its might, how many can you cast in a month?"

"My lord, although there are more than 4,000 people in the Foundry Bureau, there are only a few dozen people who can cast cannons, but there are quite a few people who can make Lu Migong.

Go all out to cast this new type of artillery, and your subordinates dare to guarantee that you can make tens of thousands of guns a month. ”

Ma Huai frowned and said in embarrassment.

People who don't understand technology won't understand that the most important thing to do these things is details and experience.

If a group of inexperienced newcomers who don't understand the details are pulled over to cast cannons, he doesn't dare to guarantee it at all.

Not to mention the scrap rate, the details alone can lead to various problems with the cast artillery.

"You don't have to worry about these things, and you don't have to give me promises.

One thing I want you to do right now is to streamline the process and technique of cannon casting.

What is streamlining?

For example, some people are good at burning molten iron, some people are good at casting guns, and some people are good at making gunpowder, so you divide the process of these people into these people, and let them only be responsible for one thing, instead of learning everything and doing everything.

In order to prevent problems in a certain link, each link must be recorded and the name of the maker should be engraved.

If you don't do a good job, you will find trouble with whom.

If you can ensure that the whole assembly line does not have problems, everyone will be rewarded. ”

Wang Zezhi paused when he said this, he wanted to give Ma Huai a little time.

It takes time for Ma Huai to digest this information.

After Ma Huai heard Wang Zezhi's method, he immediately thought about it, he was thinking about the feasibility of casting cannon streaming.

One moment he crouched down to write and draw, the other he muttered to himself.

After a while, he raised his head, stared at Wang Zezhi seriously, and said, "I need time, and I have to experiment." ”

"Just do it, just ask Wang Shan for all the things in terms of materials and money."

"Okay."

Ma Huai took the order and strode away.

After Ma Huai left, Wang Zezhi began to think.

The matter over there in the four cities of Yongping is irreparable, and he doesn't have to worry about the thieves in Shaanxi.

What he has to do now is to guard the Datong Mansion, Hetao, Tumut Department, Ordos Department, and Yongshao Bububu, these territories.

The second is to think about how to justifiably occupy the Xuanfu.

Xuanfu Town is close to Datong Mansion, and if he can make this place his territory, he will be able to rely on this place to make a move against Chahar and the Hara Shen Department who led the way to Huang Taiji.

The Chahar Department was originally under the command of Lin Dan Khan, and after Wang Zezhi defeated Lin Dan Khan, they took refuge in Huang Taiji.

The most important thing is that the Chahar division belongs to the right-wing Mongolia and occupies the eastern part of Monan Mongolia.

On the side of the couch, how can others sleep soundly, Lin Dan Khan has been defeated, and these people have no reason to continue to live here.

The king must conquer them for his own use.

The Harashen Division, that is, the Karaqin Division.

Huang Taiji's expedition to Ming is the road led by this tribe.

In 1628, Lin Dan Khan defeated Karaqin at Tumut Zhaocheng (now Hohhot), and the Karaqin tribe was scattered.

Duoyan attacked the name of Karaqin.

The surname of the leader of Duoyan is Uliangha, and he is a descendant of Zhele.

In the early years of Tiancong of Taizong of the Qing Dynasty, Su Budi, the leader of Duoyan, was attached to Huang Taiji and compiled Karaqin as the Erzazak Banner.

When Yuan Chonghuan supervised Liaodong, in order to stabilize the Mongols, he also specially allocated some military rations and sold them to them.

didn't think about it, they turned their heads and gave it to Huang Taiji.

This is how Yuan Chonghuan came from the charge of betraying the country by the enemy.
