This time, the alliance between Ming and Mongolia is more specific and in-depth than the last one.

In addition to the border trade issue, the most important cooperation between the two sides is naturally the military aspect.

Tianqi emphasized: "Although it is very likely that Jianlu will attack the Chahar Department first and then invade the Ming Dynasty, it is also possible to make a detour through Mongolia to enter the Ming Dynasty and plunder it, and then conquer the Chahar Department." ”

"No matter which situation arises, both sides cannot sit idly by and watch the other party be defeated by each of the Jianyu, and must work together to resist the Jianyu."

For this point, Gui Yingcha naturally agrees very much, because it is more beneficial to the Chahar Department.

"The cooperation between the two sides is limited to resisting the Jianjiao, and the Chahar Ministry does not need to help the Ming suppress the civil uprising, and the Ming does not need to help the Chahar Ministry to quell the civil strife. Except, of course, for the Mongol tribes and Han Chinese who had already taken refuge in Jianju. ”

There's nothing wrong with that, so it's not a problem.

Tianqi also talked about the aforementioned intelligence sharing, joint reconnaissance of information about Jianguo, and even plotting against the Han and Mongols who surrendered to Jianguo, assassinating high-ranking generals in Jianguo, and planting spies, etc.

In fact, in Lin Dan Khan's mind, it was already very good that the two sides could share information about Jianyu and conduct joint reconnaissance, but as for going deep into Jianguo to plot rebellion, assassination, and planting spies, etc., he didn't think about it at all, and he didn't think it was realistic.

Because he knows that Jianyu's internal management is very strict, and it is not easy to do this.

Moreover, the entire Liaodong, as well as the Mongolian left, was almost controlled by the Jianyu, and it was also a huge challenge to implement these strategies across such a long distance, and it was a waste of manpower and material resources.

However, the apocalypse is still very persistent, and it doesn't mean that these actions should be arranged immediately, let's act when the opportunity arises, we even rebelled against Nurhachi's son-in-law, what is impossible?

In the end, the Apocalypse emphasized that the Ming Dynasty was the mainstay, and the Chahar Ministry only needed to help at special times, and Gui Yingcha didn't say much, anyway, it didn't require much strength from the Chahar Ministry.

Finally, Tianqi emphasized the responsibility of both sides, if it was the cause of the Ming army that caused the loss of the Chahar Division, then the Ming court would severely punish the relevant generals and bear the compensation for the casualties of the Chahar Division.

In the same way, if it is the reason of the Chahar Ministry, then Lin Dan Khan will also be held accountable to the relevant generals and bear the losses of the Ming army.

In fact, the apocalypse is more inclined to unified command, but considering the differences and contradictions between the two sides for hundreds of years, and the lack of such conditions for trust, this idea is hardly realistic.

So retreat to the second, can only be restrained in this way, so as not to pit each other at a critical moment.

For this point, Guiying was a little hesitant, because when Tianqi talked about this matter before, he only mentioned the Ming army, and did not say what responsibility the Chahar Ministry needed to bear once it failed to take responsibility.

But this is very unfair to the Ming army, so it is understandable that Tianqi has made such a supplement, and Gui Yingcha has no way to refute it.

Besides, in his mind, the various battles within the Ming army were very fierce, and the probability of fleeing without a fight, watching from the sidelines, or holding the troops was much greater, while in the Chahar Department, Lin Dan Khan's orders could be better implemented, and no one dared to disobey easily.

Therefore, even with such constraints, it is generally more beneficial to the Chahar Department.

It is precisely because of this measurement that Gui Yingcha also agreed.

Subsequently, the two sides discussed a number of other details, and finally finalized a formal treaty of association.

This is a relatively fair treaty, and in Guiyingcha's view, the overall content of the treaty is more favorable to the Chahar Ministry.

Of course, he would not be naïve to think that it was the reason why the Ming Kingdom needed the Chahar Department more, and it could only be attributed to the bearing of the Central Plains Dynasty.

And Apocalypse's efforts to form an alliance with the Chahar Department are just to resist the first entry of the Jianyu, and he wants to block the Jianyu as much as possible and minimize his own losses, and this effort alone is obviously not enough.

So, Apocalypse quickly made two more decisions.

First of all, in all the important cities of North Zhili, the angular structure was repaired from north to south, and forts were built.

Angular defense is the concept of the western fortress, combined with the original advantages of the eastern city, it will definitely make the defense of the city stronger, which was also proved in the battle of Ningyuan.

Because Ningyuan City absorbed the advantages of the fortress, added prominent edges and corners around the city wall, and then built a fort on it, so that it could attack the enemy's siege team in a larger area, so that the Jianyu suffered heavy casualties under the city.

And it was Sun Yuanhua, an artillery expert from the Academy of Engineering, who introduced this structure, so Tianqi did not hesitate to hand over this important task to him, and Sun Yuanhua also gladly accepted the order.

Now there is money in the treasury and some jobs to house the homeless, killing two birds with one stone.

Secondly, another important decision of the Apocalypse was to purchase more Hongyi cannons from the Portuguese Artillery Factory in Macau, and then place them on the angular city.

At the same time, let the Portuguese send some artillery instructors to help the Ming train more artillery talents, so as to be able to better play the role of the Hongyi cannon.

This is a lot of money, but there is no way, because the overall cannon casting process of the Ming Dynasty is still inferior to the Portuguese, and even the way of using artillery such as calibrating and shooting Zhuyuan is also inferior.

What's more, it takes too long to cast a cannon, at least several months, and I don't have that much time to wait, because it may not take a year and a half to come.

Get through the current difficulties first, and then think about developing your own military industry.

Now there is no shortage of people who are familiar with Western missionaries, and Xu Guangqi, an academician of the Chinese Academy of Engineering, has also repeatedly suggested the purchase of Hongyi cannons, and he has met several influential missionaries, so this matter is directly handed over to him.

After this arrangement, the money in the treasury is going to flow out like flowing water again, so the apocalypse wants to make money again.

In fact, he already had an important goal, and even this goal appeared in the mind of the apocalypse one step ahead of King Fu, that is, the eight families of the Jin merchants.

These eight families are not only very rich, but more importantly, they act as the lackeys of Jianlu, secretly delivering materials to Jianlu, and constantly providing all kinds of information for Jianlu, which is full of scourge.

Therefore, the apocalypse couldn't help but attack them a long time ago.

However, the eight Jin Shang families are different from King Fu, although King Fu has a respected status, he is subject to many restrictions and has little influence in the court.

The eight Jin merchants are different, for their own safety and to obtain more information, they have made friends with a large number of powerful people in the DPRK and China through various means.

If you act rashly, it is not only easy to startle the snake, but also easy to encounter many obstacles, so before taking control of the eunuch party and the Jinyi guard, Tianqi does not dare to act rashly.

But why did the Apocalypse still make a move to King Fu first after basically controlling the eunuchs and Jinyiwei?

Because Tianqi only knows the eight Jin merchants, but it is not really which eight, he only remembers that there are those surnamed Fan, those surnamed Wang, those surnamed Tian, and one surnamed Jin, the reason why they remember the Jin family is because their surnames are the same as a well-known actor.

As for the other four, Apocalypse didn't even know their surnames, let alone the names of their family heads.

Since it is going to move, it will definitely have to be wiped out, so these days, Apocalypse has been confirming specific targets in order to strike accurately.
