As I said before, the Beishan mine was the lifeblood of the rise of the Zhao Kingdom. Relying on the high-quality iron ore produced in the Beishan Mine, Zhao Guo had the sharpest sword, the sharpest sword, and the most solid iron shield among the Seven Kingdoms, which was almost their greatest reliance on invincibility in the era of foot warfare.

Before the appearance of Daqin's iron cavalry, foot combat and chariot warfare were the most mainstream means of conquest on the battlefield, and at that time, Yan and Zhao were extremely powerful overlords in the north.

Today's Beishan Mine, the ore vein resources are gradually depleted, and Zhao State attaches great importance to it as before, and now it has become a place where war criminals and prisoners of various countries are held.

Zhao Zhiyun had previously infiltrated the valley near the Beishan mine with all the homeless nobles to take refuge, and there were two things to consider.

First, the effect of a light is black, whether it is the pursuers of Zhao State or the unclothed army chasing them in Yan Kingdom, neither of them would have thought that Zhao Zhiyun would throw herself into the net and take the initiative to drill into the heart of the prisoner of war camp.

Second, as the new force of the younger generation of Yan Kingdom, they are far from having enough strength to revive the former Yan Kingdom, and they need the wisdom and experience of the older generation. Therefore, those Yan veterans in the Beishan mine, they did not give up, as long as they had the opportunity, they would definitely rescue them from the prisoner of war camp.

Although most of the troops in the Beishan Mine have been transferred away one after another because of the war with Qi, there are still at least seven or eight hundred people stationed at the moment. And these seven or eight hundred people are all well-armored, fully armed elite soldiers of the Zhao State.

With the 300 rabble in Zhao Zhiyun's previous hands, if he wanted to break into the Beishan mine to save people, it was simply a fool's dream, and in the end, people were not rescued, and they had to trap themselves in.

After Xue Ding joined, he had a deep discussion with Zhao Zhiyun about this issue.

Xue Ding said at the time that the Beishan mine must be fought, and the Yan Guo soldiers in the mine must also be saved.

After the establishment of the comrade battalion, Schröding set a big goal for everyone, and set countless smaller goals.

The big goal is very straightforward, that is, a breath remains, and the courage is restored. This is the consensus between him and Zhao Zhiyun now, combining the precepts of the Zhao family of Yan Kingdom with the brave martial arts of the Iron Cloth Army.

There are too many small goals, many of which are small implementation steps, but most of them are proposed by Schröding.

It can be seen that although Xue Ding has been hidden in the market and has been an ordinary blacksmith over the years, if he has never really let go of Yan Guo for a moment in his heart.

He may have also thought in his heart that he would have an army in his hands, and how he would lead this army to get the Yan Kingdom back little by little.

Who knows how many times he has gone through the deduction of the sand table in his mind before he can summarize the process of Fuyan's first stage, the implementation steps, and the problems encountered are all taken into account.

Schröding probably wouldn't have imagined that he would get his wish in such a situation.

Although what was handed over to him was not a million lions, nor was it a strong tiger and wolf journey, but there were more than 100 young people of the new generation with sincerity to serve the country.

Starting from scratch, what is there to fear? The fire of war in Schröding's chest was rekindled.

He didn't want to take his sister back to the dilapidated blacksmith shop, and he saw hope in the young men.

"We have a limited number of people, so we can't divide our forces to attack the problem. "In front of Xue Ding, Xue Ying and Zhao Zhiyun, there is a small simulated sand table.

Because of his many years of military habits, Schröding would observe the terrain everywhere he went and keep it firmly in his mind. When he entered this Ghost Yin Valley, he also had to carefully observe the terrain.

I don't know if Zhao Zhiyun really knows how to choose a place, or if she is blindsided, at the moment, this Ghost Yin Valley is indeed an excellent strategic entry point.

If it weren't for the lack of manpower at the moment, Schröding felt that he was fully capable of turning this place into an impregnable city.

With all the bows and crossbows and enough arrows, giving the Zhao army 10,000 people may not be able to break through here.

Of course, this is ideally, but now they are understaffed, and this crossbow and arrow are also in short supply.

All the bows and arrows that could be used by General Schröding were concentrated.

Some of these ordnance were collected by these young people's homes, and many of them were looted from the battlefield.

In the Yan Kingdom back then, there would always be some nobles who liked to shoot and hunt, whether it was a crossbow or a hunting bow, in fact, they were not as good as the ordnance used in the army, and they were used repeatedly along the way, and they were not maintained in time, and only three or two of the ten pieces could barely be used at present.

As for the arrows, they add up to only a hundred or so in total, and in the battlefield, even a wave of splashing can't be done.

"Here, here, here, you pay attention to these places, these places will be the places where Zhao Bing set up bunkers and arrow towers. Schröding took the twig in his hand and pointed at the sand table.

"We've had people spy on these places before, haven't you seen the Arrow Tower?" Zhao Zhiyun didn't just stay here after entering the valley, she also sent people several times to explore outside the valley, and even to the Beishan mine.

Schröding shook his head: "The fort has a bright castle and a dark fort, and the tower has a hidden tower, you can observe the distance too far, and the Ming Castle can be seen, but the hidden castle and hidden tower can only be found when it is close, but once it is close, it is usually difficult to avoid being exposed." ”

Zhao Zhiyun nodded, she had also heard her father talk about this, to speculate on the location of the other party's Hidden Fortress Hidden Tower, that can only be done with rich battlefield experience, obviously she has not yet reached that skill.

Schröding's addition just filled her vacancy in this area.

"I need to organize a team of people, not more than six or seven people, agile and skilled in archery. Xue Ding turned his head and glanced at Xue Ying, Xue Ying was leading the team in training recently, and Xue Ding was preparing for war, so when asked about the selection of fighters, Xue Ding subconsciously looked at Xue Ying.

Xue Ying nodded: "Luo Cheng's team can be used, their cooperation is very tacit, there are strong attackers and archers." ”

The training method of the fellow battalion is the same as that of the Iron Jacket Army, which is divided into small teams for group training.

There will be all types of fighters in the squad, and the team members need to cultivate a tacit understanding with each other in training, so that when put on the battlefield, this squad will be like a steel needle, tearing apart each other's defenses and breaking the enemy's barriers.
