Although it was a joke, Zhang Liao didn't dare to pick up this topic casually, because Liu Xuan's casual sentence of 'dragon slaying knife' was too terrifying.

But all emperors, like to the true dragon son of heaven, and the dragon as the symbol of the emperor, this source is said to be traced back to the Yellow Emperor period, in the Qin and Han dynasties was thoroughly carried forward, it can be said that the name "dragon slaying", itself is taboo.

Liu Xuan naturally wouldn't have thought of this, so the sentence just now was really just a joke, not to mention that his current identity was also very taboo about the dragon slaying knife - after he cultivated the dragon qi of the Son of Heaven, he paid more attention to this kind of opposition in name.

What's more, the weapon he is casting now may have some effect, if he really casts a divine weapon that can break his Heavenly Son Dragon Qi because of a casual joke, then isn't he making himself uncomfortable?

However, the weapons used by Zhang Liao in history do not seem to be very famous, and I don't know what kind of weapon Zhang Liao will refine in the end?

In addition, Liu Xuan's refining method does not mean that every weapon will be tempered into a special weapon, there is a high probability that there will be no change, the original is still what it is, but it is stronger and sharper than ordinary mortal iron, and there is nothing else.

I can't guarantee that Zhang Liao doesn't have the luck in this regard, and in the end he only quenched an ordinary big knife!

Liu Xuan felt that there was no need to worry so much about these things, although he valued these civil and military courtiers, he would not have to take care of everything after eating, drinking, and Lazar, and he was not the father of these people - not to mention that even if it was his father, he would not be so lenient.

chatted with Zhang Liao again, and at the same time asked about Yu Linqi's current situation.

Since the defeat of Li Dao and Guo Yan, the Forbidden Army, the Tiger Ben Army, the Yulin Cavalry, and the Tiger and Leopard Cavalry have all been strengthened to a certain extent - and even the trap camp that has been under the Tiger Ben Army has been expanded to 1,000 people.

Although the expansion does not necessarily mean an increase in combat strength, after all, it is necessary to take into account the training, morale, equipment, and other factors of the soldiers, but the increase in the number of soldiers is definitely a good thing, and at least it is more generous to mobilize when employing personnel.

Compared with the forbidden army, the tiger army, and the tiger and leopard cavalry, the soldiers and horses that will be trained as elite troops are the most important for Liu Xuan, and the Yulin cavalry is also average.

After Zhang Liao commanded the Yulin Cavalry, although he did not make any achievements, because Liu Xuan, a soldier of the Yulin Cavalry, could see it every day, he was able to observe the changes in this army nearby.

At the beginning, Cao Cao laid a good foundation for this army, and Zhang Liao did not discard those good things, but added his own understanding of cavalry troops to that foundation - emphasizing mobility and survivability.

Zhang Liao's Yulin cavalry, the cavalry did not pay heavy armor, but wore some light armor to protect the vital points, and at the same time, each cavalry carried a bow and arrow, and riding and archery has now become a subject that Yulin cavalry must master. At the same time, the soldiers of the Feather Grove Cavalry carried not spears, but one-handed swords, which seemed to prove that the style of the Feathered Cavalry would not be the same as that of the Tiger and Leopard Cavalry.

Liu Xuan saw everything in his eyes, and he had also discussed these things about Yulin Riding with Zhang Liao.

"The bow is not easy to master, why not use a crossbow?"

Liu Xuan didn't have a deep understanding of the weapons used on the battlefield in this era at that time, and he only made suggestions based on some impressions in his mind, and Zhang Liao explained on the spot why he used a bow instead of a crossbow.

It turned out that the crossbow used by the cavalry at this time was not the kind of infantry crossbow that was wide and wide, and the arrows on the string needed to be assisted by feet, but a very light hand crossbow - light is lightweight, and it is also easy to carry, but the power is really not enough. Even slightly thicker armor can't shoot into it.

And the range is also very close, and the weight of the crossbow itself is also light, whether it is lethality or range, it is far inferior to the bow and arrow, so Zhang Liao chose a bow instead of a crossbow for Yulin Riding.

Liu Xuan also considered letting the cavalry use the infantry crossbow, because according to his expectations, these soldiers would all start cultivating in the future, and even if the infantry crossbow was heavy and difficult to open the bow, it would not be difficult for the soldiers after cultivation.

But Zhang Liao quickly told him: "The infantry crossbow is too large to be carried and used by the cavalry, and there is not enough space on the horse for the rider to do such a troublesome step of loading the arrow, which is not as convenient and fast as the bow and arrow."

Liu Xuan listened, and then realized that because of technical problems during this period, many of the ideas in his head were not feasible, so maybe he should change his plan a little?

Originally, his plan was to start with a few elite troops to implement the cultivation method, and then start to radiate to the forbidden army, and then slowly spread it to the national army.

As for the transition from military to people's livelihood, it was at the same time, just using some immortal methods on people's livelihood, only he could handle it by himself at the moment, and he also needed those Wenchen to cultivate as soon as possible and master the big pile of technology.

These techniques cover many aspects such as refining weapons and alchemy, even if they start cultivating now, they can't be cultivated in a moment, so Liu Xuan can only take his time. First focus on military affairs, and then wait for the training of subordinates to start working on people's livelihood.

For example, if he had enough subordinates who knew enough about those methods, he could immediately implement them to all the counties, instead of waiting for this batch of grain to evolve on its own.

Now it seems that the technical 'upgrade' must also be put on the agenda, because if this continues, sooner or later there will be an embarrassing problem: their soldiers have become strong enough, but the weapons and equipment cannot keep up with the speed of the soldiers' 'upgrade', and they can only use weapons that are not good at hand to fight.

"But what is most lacking in this era is technical talents!"

Liu Xuan thought about it, and he couldn't think of a few talents who were good at research, and the only thing he could think of was naturally the future Prime Minister Zhuge of Shu Kingdom, but now that Prime Minister Zhuge is still a little kid, it is estimated that he has not learned anything, even if he finds it, what is the use?

"Do you want to cultivate it yourself?"

Shaking his head, isn't he just cultivating talents now? It's just that when the imperial court is also in the process of employing people, there are not enough talents to govern everywhere, so how can there be time to specialize in cultivating talents in this area?

Many things were not satisfactory, and they were too different from what he thought, so he simply didn't go to participate, just quietly observed how Zhang Liao trained Yulin Ride, and at the same time learned about all aspects of this period nearby.

Of course, Liu Xuan will still bring up some advanced things from time to time to satisfy his sense of superiority as a 'wearer', such as the kite tactics that swept through Eurasian countries, and he told Zhang Liao.

"This tactic is not unusual, but I have never seen it used on a large scale......"

Most of the northern nomads have the art of riding and archery, so Zhang Liao also saw those steppe people use similar tricks against them when he was merging the state - but at that time, those alien races were the side with few people, and they instinctively thought that it was a last resort for them to use when they were at a disadvantage......

The rain of arrows smashed down overwhelmingly, but when he chased after him, the other party turned his head and ran, and then as soon as he slowed down, a large area of arrow rain fell......

Trembling all over, Zhang Liao realized how terrifying this tactic is, which can only be beaten and cannot fight back, just if you want to fight like this, you have to have a thick enough skin, because it is too shameless.

Peeking at the Son of Heaven, he wondered how the emperor could have thought of such a shameless tactic, but he also had to admire the emperor, if this shameless tactic could be displayed, then as long as there was enough space, it would be an invincible existence.

But the problems to be solved are not without - first of all, archers are more difficult to train in the army, and this method of warfare has higher requirements for soldiers, that is, soldiers must also know how to shoot on horseback.

Archery on a horse is very different from archery on the ground, and the requirements for soldiers are higher, not only good archery, but also riding to a certain level.

Fortunately, Liu Xuan made another 'invention' and explained the principle of the stirrup, Zhang Liao's eyes immediately lit up, and he was keenly aware that if this thing was made, the power of the cavalry would not only increase a lot, but also reduce the requirements for ordinary soldiers to become cavalry.

After Liu Xuan said all these things, he was secretly thinking: "I don't need to do the money for burning glass, making wine, etc., but this stirrup and 'kite tactics' have been drummed up, and it is not in vain that I came to the end of the Han Dynasty." ”

Just because of Liu Xuan's suggestions, now Yulin Riding has some changes compared to the original - the armor on the body is lighter, except for the helmet, there are only a few key points to cover, that look is basically a heart shield on the chest, and a piece of armor on the back that is slightly larger than the heart guard, in addition, each Yulin rider has a feather inserted in the helmet, which is considered to show his identity.

With the exception of the long knife at his waist, all the weight of each cavalryman's horse was used to carry arrows. However, according to Zhang Liao, this kind of Yulin cavalry does not have the ability to go out to fight, because they cannot carry food. If the Yulin Cavalry really wants to form combat effectiveness, it will at least need two or even three times the size of the soldiers' war horses, which will be specially used to carry rations and drinking water.

Because of this method of warfare of the Yulin Cavalry, they are destined to have no logistical baggage troops, and they cannot burn and loot in the same place as the aliens, unless they are fighting in other countries.

After Liu Xuan took out the formula to improve the ability of the war horse's weight, Zhang Liao felt that these problems were not a problem at all.

However, Liu Xuan was still not satisfied, because he felt that although Yulin Qi had combat power, it was ......

"Yulin Cavalry is the ace elite soldier of the Han Dynasty, this appearance must not be too bad, the current appearance is ......" Liu Xuan looked at this group of soldiers who were not as good as the 'Bronze Saint Seiya', and there was a burst of dissatisfaction in his heart, and he had to change Yulinqi anyway.
