Yang Cong was thinking about how to clean up Chen Da, and Chen Da was naturally thinking about how to clean up Yang Cong, but the two of them couldn't think of any good way for a while.

Chen Da is confined to Shanxi, although he has great power, he can't control Yang Cong, a Beijing official, if he wants to clean up Yang Cong, he still has to rely on Xia Yan, a cabinet scholar.

Yang Cong is not very familiar with Shanxi, and he doesn't know what Chen Dadu has done, so he doesn't know where to start.

He discussed with Zhu Xinli in the Jin Palace, signed the contract and returned to Dingxiang, and at this time he could not return to the capital, because his parents had to hand over the silver to the Jin Palace, and send someone to take over the 100,000 acres of rented land, and at the same time had to hurry up to buy grain, and send someone to Datong Town in exchange for salt.

These are not easy to fake the hands of others, most of them can only be done by his parents themselves, so his parents will not be able to go to the capital with him for a while.

He came specifically to pick up his parents, so it was naturally impossible to go back without his parents, and he also wanted to find a way to clean up Chen Da, and he was not in a hurry to go back to the capital.

So, how to clean up Chen Da?

He thought about it for a long time, and finally thought of a good way, that is, to use the Tartar to make a fuss, which Xia Yan "taught" him, Xia Yan used this trick to make Nie Bao and Zhang Shiche almost suffer a loss, so that Zhang Shiche almost didn't become a Nanjing household secretary.

This trick seems to be good to use against Chen Da, Nie Bao and Zhang Shiche, who have little to do with this matter, can be implicated, Shanxi, which is densely populated here, has been invaded by Tartars so many times, doesn't the governor of Shanxi have any responsibility?

Moreover, he also wanted to understand why the Tartars were able to wreak havoc on the border towns, and at the same time, he also wanted to see on the spot why the border army of the Nine Towns had no way to take the Tartars.

The number of border troops in the nine towns of the Ming Dynasty is actually very large, it can be said that it is terrifying, and it is not comparable to a Northern Yuan Tatar department at all.

This point, Yang Cong has already understood with Cui Hao and Zhu Bingzhong, according to the establishment of the Hongwu period at the beginning of the Ming Dynasty, the number of border troops in the nine towns of the Ming Dynasty has reached a terrifying more than 1.6 million!

Of course, the number of border troops is not so large now, and the nine sides of the Ming Dynasty have undergone several changes, and the number of border troops has decreased sharply.

For example, during the reign of Chengzu Yongle, after the Battle of Jingjing, the nine major vassal kings either moved inward or reduced their powers, and the number of border troops in the nine towns decreased sharply for the first time, from more than 1.6 million to more than 1.2 million.

For another example, during the orthodox years of Yingzong, due to the defeat of the Ming army in the Battle of Tumubao and heavy casualties, the number of border troops in Jiuzhen decreased sharply for the second time, from more than 1.2 million to more than 800,000.

However, even if the number of border troops of the Ming Dynasty is sharply reduced, it is not comparable to a Northern Yuan Tatar department, take the three border towns in Shanxi as an example, Xuanfu Town, Datong Town, Taiyuan Town, the number of border troops in the three towns is more than 200,000!

Among them, Xuanfu Town Wanquan Du Division subordinate Wanquan Left Guard, Wanquan Right Guard, Xuanfu Qianwei, Kaiping Guard, Longmen Guard, and other 15 guards and six guards, a total of more than 90,000 border troops.

Datong Town, Shanxi Xingdu Division, subordinate Datong Left Guard, Datong Right Guard, Shuozhou Guard, Zhenyu Guard and other 14 guards three guards, a total of more than 80,000 border troops.

Taiyuan Town, Shanxi Capital Division, subordinate Taiyuan Left Guard, Taiyuan Right Guard, Zhenwu Guard, Pingyang Wei and other nine guards, thirteen guards, three herdsmen, more than 60,000 border troops.

The guards of these guards are not the same as those in the inland that are pure tuntian, they all have weapons, and the establishment is relatively complete, even if there are guards who escape, they will be quickly made up, they are the border army, if the foreign enemy invades, they have to pick up arms!

However, not all border troops have food, if all border troops have food, then the Ming court alone in the three border towns of Shanxi more than 200,000 border troops can not afford it.

Like Zhenwuwei, who is only responsible for garrisoning Yanmen Pass and Daizhou, and does not need to run around, there is no food, and what really has food and salary are those who are assembled together and under the command of the general army and need to fight everywhere, Xuanfu Town, Datong Town, Taiyuan Town, such border army elites are only about 10,000.

What Yang Cong wants to see is these elite border troops, logically speaking, these carefully selected elite border troops should be stronger than the Tatar cavalry, and the elite of the border army in the nine towns add up to more than 100,000, which is about the same number as the Tatar cavalry, and there is also the convenience of the location, and there are nearly ten times the number of guards to help, why can't they kill the Tatar cavalry?

With this question, Yang Cong and Cui Hao came to Ningwuguan, the border army garrison of Taiyuan Town, which was closest to Dingxiang.

Ningwu Pass is the location of the general garrison of the town guard of Ningwu, Ningwu and Yanmen three passes, the first year of Jingtai of the Ming Dynasty began to build the city on the Huagai Mountain in the Guan, Chenghua, Zhengde years after several expansions, this Guancheng was finally named Zhenshuo City.

Yang Cong and his entourage of more than 100 people set off from Dingxiang, rode horses for about two hours, and then rushed to Shuocheng, Ningwuguan Town, located in the northwest of Xinzhou.

This guy, when he saw the majestic Guancheng on the mountain, Yang Cong was really shocked.

The area of Zhenshuo City is actually not large, and the city wall on one side is more than a mile long, but its majesty is enough to make people prohibitive.

Because this Zhenshuo City was originally built on a mountain ridge hundreds of meters high, the only way to attack the city was to climb up and attack it through a small road that was not enough feet.

This is nothing, what is even more terrifying is that the walls of Zhenshuo City are more than three zhang high, and there are many arrow towers and forts on it, just like a huge iron hedgehog.

Hungry obediently, no wonder Li Zicheng suffered a big loss here in history, such a pass, if you want to capture it, it is too difficult.

Historically, Li Zicheng led a million-strong army from Shaanxi to the capital of the Ming Dynasty, and the road was originally smooth sailing, and basically did not encounter any decent resistance, but when he arrived here, he encountered the stubborn resistance of Zhou Yuji, the general soldier of Shanxi.

According to rumors, the bloody battle of Ningwuguan, Li Zicheng led the main army of 500,000 to attack the Zhenshuo City garrisoned by the Ming border army commanded by Zhou Yuji, which lasted half a month, and the peasant army lost more than 70,000 soldiers and wounded more than 200,000 people.

Fortunately, Yang Cong did not come to attack the city, they rode their horses and galloped for nearly two hours and were already sleepy and tired, seeing such a strong pass, he was really a little stunned, if the defenders came to a cannonball when climbing the mountain, the consequences were unimaginable!

This guy, Taiyuan Town was originally under the jurisdiction of Chen Da, the governor of Shanxi, who knows if this Shanxi general soldier is Chen Da's person, if he wants people to ignore it, pretend to be the enemy, and give himself such a time, then it will be over.

After thinking about it, he still asked everyone to get off their horses and rest, and sent Shen Lian to Guancheng to contact the defenders to misunderstand.

Fortunately, this Shanxi general soldier was not as reckless as he imagined, Shen Lian only went up for a while, and the gate of Guancheng was opened, and a general led dozens of guards to fight horses.
