As soon as he heard Liu Mu mention that these people were female soldiers, Li Jingyi waved his hand: "You can rest assured, the military regulations in my Tang Army are strict, and I will send a hundred personal soldiers to protect their safety. Li Jing understood Liu Mu's worries, so he gave a guarantee in advance.

Liu Mu said again: "Senior Brother Yao, I can't afford to equip every city in the frontier with flying scouts. You're in a big trouble for me, it takes at least a year for these people to train. I don't always say how much it costs to make those coins, you say I'm not troublesome. ”

"No trouble, the problem with the coin is a minor problem." Li Jing replied nonchalantly.

After Liu Mu took Li Ji and the old wolf back to the West Surrender City, only one day, he learned that Jieli's troops began to change lanes and really came to the West Surrender City.

When Liu Mu got the news, Li Jing also got the news.

Waving his hand to signal the flying scout who came to report to ride down to rest, Li Jing said to the generals around him with emotion: "Within two hundred miles, everything is in the eyes of the flying scout. It can fly more than 200 miles per hour, it is indeed a reconnaissance weapon, I heard that there are two more that can fly to 400 miles per hour, but at the moment no one can skillfully control it, it's a pity. ”

Li Jing said that these data were all obtained from Liu Mu.

At present, according to the calculation of the industry in later generations, it is only barely close to the specifications of the intermediate wing, and if the material cannot make a breakthrough, the cost of the advanced wing is too high.

Moreover, the operation of advanced wings is also more difficult, without sufficient proficiency and experience, cross-country flight is no different from sending to death.

Fortunately, this is a grassland, if it is a mountainous area, Liu Mu will not lend these people to Li Jing if he says anything.

In the city of Xishou, one of the best female assassins beside Baoqin, Butterfly Dance, had finished changing her costume and came to the only one-to-twelve quasi-high-level wing brought here.

She doesn't have to do anything with her, and two assistants will help her make all the adjustments.

Then there was no need for her to run, two assistants lifted her feet one left and one right, and then a dozen sturdy men in front of her pulled the long rope and began to run hard after giving the order.

After reaching a certain speed, the person riding the horse pulls another section with his horsepower.

Take-off on the ground requires assistance, and after the butterfly dance has reached a height of about five feet, it releases the rope and begins to climb faster along the wind direction.

Stand on the ground and watch the glider slowly disappear from sight.

Li Ji said to Liu Mu: "The little lady of the butterfly dance has learned the art of war, as long as she can bring back the layout of the military formation at night, our winning chance will increase by three percent." ”

"Brother Maogong, do you say that Jieli deliberately made trouble for me, or did Senior Brother Yao cheat me." Liu Mu asked Li Ji.

Li Jixiao asked: "Have you ever cheated Liu Renliang?" ”

"These two things are completely different, I have no official position, no military position, I brought out a caravan, I have no ......" Liu Mu originally wanted to say that he was not obliged to go to the front line to fight.

But when the words came to his lips, Liu Mu stopped.

In later generations, Liu Mu served as a soldier, and even if he was not a soldier, Liu Mu's education made him understand that everyone has the obligation to fight for the protection of the country.

At this time, he was in Datang, and he said that he was deeply favored and trusted by the Li Tang Dynasty. To put it mildly, he is also the Li Tang clan. What reason is there not to fight for your own Datang.

Li Ji smiled and handed a document to Liu Mu.

This is a report on the rearmament of the regiments, and it can be said that everyone has long been prepared for a bloody battle with the Turks. From the moment they left Chang'an with this so-called caravan, each of them was looking forward to a big battle.

"They want to make meritorious contributions."

"Yes." Liu Mu put away the paperwork, and his eyes changed: "Order, second regiment, go and check their equipment for me." I can only give them one chance, only once. ”

Li Ji became interested: "What kind of equipment is the second regiment." ”

"It's all my own family, Brother Maogong let's take a look, if I have the money to equip thousands of this thing, and only the logistics are guaranteed, I can destroy Goguryeo today." But a few thousand are not more than difficult, and Datang's logistics can't sustain such a war. One blow, thirty dollars. ”

Yanagi is not talking nonsense, he is according to the depreciation of a cannon, the money for shells, and gunpowder.

That's not counting the cost of training personnel.

You know, the artillerymen must read and write, and they will also calculate the number of shots.

Moreover, a telescope for sight distance is also a sky-high price for Datang in this era, and it took a lot of experiments to succeed in a pair.

In one barracks, ten soldiers were carefully scrubbing the cannon.

There are only three cannons under Liu Mu's eyes, and the cost is huge, and such a large cannon must be cast without trachoma and no breakage, and Datang's craftsmanship is still a lot of distance.

It's not that Liu Mu didn't think about casting copper cannons first, but he didn't have any contact with copper cannon casting in later generations.

However, I have read a lot of information about iron molds and cast iron cannons.

After numerous failures, the craftsmen continued to find ways to improve on the basis of the materials of the willow wood, and it took nearly two years to forge only three cannons.

Looking at this big black guy, although Li Ji didn't understand what it was, he could feel a sense of fear.

"Wood, what is this?"

Liu Mu came to the corner of the house and opened a wooden box, and the solid cannonball inside Liu Mu didn't grab it with one hand, but a long-trained artilleryman held it in front of Li Ji.

Only then did Liu Mu speak: "Shoot such an iron thing, it is faster than an arrow, and it can shoot almost four hundred paces away." Brother Mao Gong thinks that this thing can kill people? ”

Li Ji took the solid cannonball, and said in his heart that this thing weighed almost five catties and seemed to be lead.

Such a thing hits a person faster than an arrow, and it is estimated that the person will become a pile of rotten meat.

"I have a plan." Li Ji suddenly smiled.

"Draw Jie Li closer, bring him a guy." That's what Yanagi originally thought.

Li Ji shook his head: "Make a shell for this big guy, just use bamboo baskets and planks or something, and then make hundreds of shells and put them in a formation outside with this, I dare to guarantee that Jieli will never dare to approach the city five hundred steps." ”

"It's not good, what if Jieli is stupid enough not to understand that this thing is terrible, and rushes up stupidly?" Yanagi asked rhetorically.

Li Ji spread his hands: "This, it's up to you, you must have a way to scare Jieli." ”

Liu Mu shook his head vigorously: "It's not good, I'm planning to kill Jieli with one shot, although I have the way to do what you said, but I spend too much money, and if I scare Jieli and escape back to the Turkic tent, then Liu Renliang and Su Dingfang's plan will fail, and they will also die." ”

Li Ji looked at Liu Mu, he believed that Liu Mu was more concerned about whether he could kill Jieli with one shot.
