Yun Xiao thrust in the study for a long time and finally successfully made the drawings of the stone caster.

The old man Yu looked at the drawings of the trencher and muttered in a low voice: "Can this torsional spring be thicker and throw it further? Can it be made larger? Put a wheel at the bottom and pull it away with a horse."

"Old Yu, this thing is not used to kill the enemy."

Yun Xiao saw the appearance of Yu Lao and smiled.

"This thing is not used to kill enemies, what is it for?"

Old Yu became even more confused and didn't understand what Yun Xiao was selling in the gourd.

"Look, the trencher is used to throw this thing."

Yun Xiao took out a triangle nail and explained to Mr. Yu.

"The triangle nail is installed in such a pocket, and no thread is left on the edge of the pocket. Tie the thread here and throw it with a trencher. The pocket will disintegrate in the air, and the triangle nail inside will be spilled everywhere.

In this way, we can be covered with such triangular nails in front of our army in an instant, about fifty to eighty steps. If the opponent charges with cavalry, what will happen to them?"

Batu widened his eyes and looked at Yun Xiao.

"The horse will definitely jump up when it is stabbed. They don't have stirrups, so they can't stay at the horse at such a fast speed. They will be thrown to death."

No one knows the tactics of the Huns better than Batu. This method is too sudden. Traps can be set up almost instantly. The charging cavalry cannot be accelerated a hundred steps away from the opponent. If they fall into a trap like Yun Xiao, many Huns will probably be thrown out of the galloping war horses. The land in winter is so cold that it will definitely be very sad.

I really don’t know how this marquis came up with it. This is simply a disaster for the cavalry in the charge.

"Yes, the cavalry in the charge encountered such a trap. Coupled with the attack of our crossbow, even the Huns who were two or three times the same as our army would probably return in a defeat."

Dai Yu held a triangle nail in his hand, and no matter how he threw it, there would be a spike on his side facing up.

"If they stop within a hundred steps, our longbow can exert its maximum power. The longbow's firing rate is much faster than that of the iron-tied crossbow, and it will definitely give the Huns the greatest blow."

The eagle looked at the schematic diagram that Yun Xiao drew on the paper and calculated that the archery skills of the local tyrants were taught by him. Although he dared not say that they all passed through the sun in a hundred steps, it was still no problem to hit the enemy within a hundred steps.

Within a hundred steps, the power of the compound bow is not something that the Huns' leather robes can defend. It can be said that if the Huns generals dare to charge against Yun Xiao's team, the consequences will be that the entire army will be wiped out.

Listening to his subordinates' compliments, Yun Xiao smiled faintly. It is very important for the generals to understand the use of tactics. Generals must understand the equipment and tactics in their hands. This is the experience summarized by Yun Xiao.

"Our tactic is to try to eliminate the opponent on the road of attack. Many of you participated in the battle of Gaoyou. Really, swords, guns, guns, and guns. We do not have any advantage. We are all fathers and mothers who raise their flesh and blood. I don't want to lose any of you again.

I will take you out, and it will be the best victory if I can bring you all back."

All the generals were sighing. Especially in Batu. His subordinates died the most in the battle of Gaoyou, and almost half of them were killed. The scars on Batu's body would hurt from time to time when it was cloudy and rainy. It can be said that the battle gave him unforgettable pain, and this was the result of relying on the riding of a rifle and a saber. If there was no benefit of riding a rifle and a saber, it would be hard to say what the outcome of the battle of Gaoyou would be.

"Okay, the construction of equipment is also the fisherman. The training of cavalry is carried out by Batu, and the village warriors are handed over to Dai Yu and Goshawk for training. Dai Yu is responsible for teaching swordsmanship and guns, and Goshawk for teaching archery. In addition, let them get on the carriage and walk twice more in Lintong. Feel the feeling of riding in the carriage, and don't wait to experience it when you arrive on the battlefield."

"promise"

The generals of the family agreed, which was a major event that concerns their lives. No one dared to be careless and went down to prepare according to Yun Xiao's instructions.

It was just the end of July, and there were at least three or four months before the beginning of winter. The Huns had to wait for the season when the autumn was high and the horses were fat, hoping that their preparations might work. Yun Xiao, the army of the Han Dynasty, could not control it, and he could still decide the guards under his command.

No matter what, be prepared. I hope I guessed wrong, the Huns just bluffed and would not really go against the border.

Yun Xiao and the donkey wandered around the study room like a mill, racking their brains to think about the problems that would encounter if they went to the Huns. Mobility, rushing ability, equipment, equipment, horses, etc. All things were revealed in their minds one by one.

Looking at the map on the wall, Yun Xiao was worried. The long Han-Hungary border line, from Liaodong to the Western Regions, was thousands of kilometers long. There were places where the Huns might break through. Unless Yun Xiao was a god, it was impossible to know where the Huns would launch an attack.

As he looked at Yun Xiao's mind suddenly had an inspiration. Since there was a target everywhere, let's get a target that gave them a headache and let them fight.

There are still four months left, and the time is a little tight. However, it should be too late to implement it.

"Cangxiong went to Chang'an to invite General Tian Lang to come."

"promise"

I need to be as low-key as possible and dormant as possible. Tian Fen is a guy who can use it, so let him take this chapter.

At dusk, Tian Fen came to Yun's house with Cang Xiong.

"Brother Yun, why are you so anxious to find me?"

Tian Fen had never seen Yun Xiao look so anxious, so he hurriedly stepped forward to ask.

"Brother Tian, ​​I'm going to come to you, and I'm going to give you a great contribution."

Yun Xiao pulled Tian Fen to the front of the map, pointed to the map and said: "Luliang Mountain, Yin Mountain, Helan Mountain. The south bank of the Yellow River sandwiched by these three mountains is called Hetao.

When the Huns occupied Hetao, they could attack Longyou and Guanzhong at will. Especially in the Guanzhong area, the Huns' cavalry could go straight to Chang'an through Hetao. For a long time, Hetao has been a sharp sword hanging on the head of my great man.

I have a way to remove this sharp sword. I wonder if Brother Tian wants to smell it?"

"It is a great achievement to be able to take Hetao back from the hands of the Huns. Brother Yun really wants to give this credit to Brother Wei?"

"I just like to talk to smart people. The Yun family is too focused now. I want to show my face in the court. After thinking about it, I will ask Brother Tian to take over the credit.

Look, Yulin, Fugu, and Shenmu. These three places are very close to each other. There were originally cities here. We are now connecting these three cities by building the Great Wall. But now the time is tight. Let’s build three simple new cities in the middle of the three cities, and then build the Great Wall after the Huns invade this winter.

The Huns were good at fighting in the field but not at attacking difficulties. We built them all the way, relying on the city wall to move within a radius of three to five miles. In this way, the Huns would be squeezed out of Hetao by us in a few years.

At that time, there were fortresses everywhere in the Hetao area. Even if the Huns invaded again, they had no choice but to chew them little by little. Speaking of defending the city, our Han army was still afraid that they would not succeed."

Yun Xiao's method is very simple, it is the Lian Castle tactic in the Empire era. I support all the troops to fight around the castle one by one, and the company will go all the way to your home. The Huns have limited tactics of siege, and the company's Great Wall is not afraid of being surrounded and killed. This kind of fighting method can make the Huns hit the wall with a headache.

"But this method seems to consume too much national strength. Qin Emperor hollowed out the empire's treasury because of the construction of the Great Wall. In the end, it led to the collapse. Will this happen..."

Unexpectedly, Tian Fu still has some vision and understands the economy of war.

"Brother Tian is too worried. We should not build it as anxiously as Emperor Qin. We should build it bit by bit. One mile will consolidate one mile and occupy one mile, and then build it forward. This is a long-term project. It is impossible to start construction at the same time as Emperor Qin. This will lead to excessive loss of national strength.

Moreover, the place we want to build is not on the long Han-Hungary border, it is just a place in Hetao."
