Unconsciously, Jia Ke quietly formed two systems among his subordinates, one was the regular army of Xuanhua and Kaiping towns under his command. Although these people were loyal to him, there were still some constraints of the imperial court. The other set was completely his, the Manchu Eight Banners established by his own hands, and this force was completely under Jia Ke's orders, and Jia Ke could use them to attack anywhere.

These two systems form Jia Ke's two treasure knives, which are both unified and mutually subordinate. This makes them both one and a check and balance.

In the next few days, in order to verify his judgment of their combat effectiveness, Jia Ke held several confrontations between the Manchu Eight Banners and the regular army. The two sides went back and forth on the prairie in a simulated war.

It was used by all in war, with bows and arrows wrapped in wood with lime, spears, and wooden knives. This will not only reduce unnecessary casualties, but also show the combat effectiveness of both sides.

The result of the war was successive victories over the Manchu Eight Banners, brainwashed by Jia Ke, who now regarded Jia Ke's death as a kind of honor.

Coupled with the fact that the current Manchu Eight Banners, like the troops in Kaiping Town, were equipped with paper armor, and in the case of little difference in weapons, the Tatars achieved a decisive advantage in the physique exercised in the cold regions of the north.

And they are not afraid of death when they fight, and now they are well-equipped, when they can't break through the regular army of Kaiping Town, they will attack from both sides, and even outflank the back road, once the cavalry of Kaiping Town can't stop them, then the slow-moving Macedonian phalanx will face the arrows like raindrops of the Manchu Eight Banners, even if they wear paper armor, they can't hold on for a long time. In the end, it is generally a situation in which the Manchu Eight Banners suffered heavy losses and the regular army of Kaiping Town was defeated.

This had never been the case in previous wars with the Tatars, who had not been systematically trained and were very poor in their ability to bear casualties, and in the past they had only one or two casualties, and their troops could scatter in a hurry. And the Manchus who have been trained and brainwashed by Jia Ke, even if they suffer fifty or sixty percent of the casualties, they can still charge forward without fear of death.

The main problem of the regular army in Kaiping was that the cavalry could not match the Manchu Eight Banners, and the number was small. Although these cavalry have been carefully trained by Jia Ke, after all, there is a big gap between them and the Tatars in terms of horsemanship, and their bodies are not as strong as the Tatars, so if they can still win against the Tatars who are poorly equipped, but against the Manchus with the same equipment as them, they will be at an absolute disadvantage.

After Jia Ke saw this situation, he felt that the Manchu Eight Banners could not be allowed to have such a great advantage over the regular army, otherwise the strength in his army would be in a state of imbalance, so he improved the bows and arrows of the regular army.

The former ordinary bow and arrow were replaced by a powerful English longbow, the longbow is generally about 1.5 meters long, the back of the bow is bent from a complete piece of wood, and the good bow is made of yew wood, which is hard and elastic. The effective firing range of these longbows reached three hundred meters. The longbowman can unleash a high parabolic arrow to attack the upper part of the enemy. And the weakness of the war horse is the attack from above, most of the war horse has no armor, so once injured, it will become difficult to control. And even at a limit distance of three hundred meters, conical arrows can penetrate ordinary chain mail. These improved English longbows are very powerful, and they are not at all able to resist the current paper armor, so that at least to a certain extent, the combat effectiveness of both sides is back to the same running line.

This improvement effectively suppressed the attack of the steppe cavalry, and could bring huge casualties to the steppe cavalry. Even if the Manchu Eight Banners were equipped with sophisticated paper armor, if they wanted to pass through these arrow rains, they would suffer very heavy losses.

But these longbows also have a fatal weakness, that is, because the pull force is too strong, and the longbow is particularly huge, so it has a huge test of the archer's physical strength. But it also has a huge advantage, the bow body is a single wood, the process is relatively simple, and it is very convenient to make and supplement. Unlike traditional Chinese bows and arrows, although they have huge advantages in flat shooting, their production process is too complicated. And there is a huge gap between the longbow and the English longbow in terms of maximum range and power.

After the regular army of Kaiping Town is equipped with the English longbow, it can release 10~20 arrows against the enemy troops 300 meters away in one minute, such a powerful and dense arrow rain is enough to cause huge casualties to any army. But such an attack could not last, but for the short time that the cavalry charged, one or twenty arrows per minute was enough.

And after successive defeats in Manchuria, the Eight Banners of Manchuria also found a way to relatively restrain the English longbow, which was to move continuously and rapidly on the periphery.

Then look for the weakness of the regular army in Kaiping Town, avoid the front of the English longbow, and take advantage of the slow speed of the English longbow and arrows, and continuously dodge and approach quickly.

Then, taking advantage of the characteristics of the Central Plains bow and arrow equipped to be superior to the longbow of Youeng England in a straight line, he gave full play to the characteristics of his excellent riding skills and continuously released arrows in the constant approach.

That's also because of the English longbow, although the bow and arrow flew a longer distance and was more powerful. However, the flight speed of the arrows it released was far behind that of the Central Plains bow and arrow. As a result, the troops only had to move quickly and flexibly to avoid the blows of the English longbow.

Although the English longbow had such and such shortcomings, his appearance put the two armies in a state of balance. The next few exercises were carried out, but there was no one-sided situation. Even if one side wins, it will also be attacked by the other side and cause huge casualties.

Time passed slowly in this non-stop training of the troops, summer was coming to an end, and autumn was coming again. This heralded the beginning of the Tatar invasion this year.

And Jia Ke is now a soldier with enough food, whether it is a Manchu or a regular army in Kaiping Town. Looking at the world, it can be called elite. And the biggest difference between them and other troops is that they can withstand far more than the casualty ratio of other troops. Just one can increase the chances of Jaco's troops by points.

The Tatars tasted great sweetness in their invasion of the Central Plains for several years in a row. Although in Kaiping Town, in the direction of Jia Ke's guard, they lost some men and horses, but on the whole, they still gained a lot. Each tribe has received a large amount of material replenishment because of several southward trips, and the population of the tribe has decreased very limited in recent years. This made the tribes enthusiastic about going south.

Now the invasion of the Central Plains every autumn has become the consensus on the grassland, because they found that there was no one in the Central Plains Dynasty except Jia Ke who was their opponent.

Jia Ke sent a letter to the imperial court at the end of the summer. The gist of it is: if the Tatars invade again this year, and the two directions of Xuanhua and Kaiping are relatively peaceful, I hope that the imperial court will allow him to lead the cavalry into the steppe, and use his own way to govern his people, and the steppe tribes will carry out a lot of plunder. In order to achieve the purpose of encircling Wei and saving Zhao.

Jia Ke didn't expect that his letter would cause an uproar in the court.

The three scholars in the study were quarrelsome because of Jia Ke's letter.

The scholar Li Lu appreciated Jia Ke's view very much, which could play a role in encircling Wei and saving Zhao, and could eliminate a large number of Tatars but had a living force, so why not?

However, Yan Mu, a scholar of the university, believed that such a rash attack, if he was defeated, would suffer very heavy losses, and he would not argue about the direction when he arrived on the grassland, and the grassland tribes lived in the grass and their whereabouts were unknown, and it was completely dependent on luck to achieve many war results. It is better to let Jia Ke's elite soldiers wait to rescue the Quartet at any time.

Finally, there is the university scholar Pan Yong, this old man is completely a knower, what do you say about the inner king and the outer saint, there has never been the Central Plains Celestial Empire, sending people to kill innocents indiscriminately, which is against the way of Confucius and Mencius, but for this set, Li Lu and Yan Mu are scoffing, who doesn't know how this Pan Yong climbed up, and now he is dressing himself up like a righteous gentleman, but it is just a cover-up, he has no choice.

The three college students were almost divided into two factions, only the scholar Li Lu firmly agreed with Jia Ke's method, and the other two scholars did not care what the reason was? One premise is that they do not agree with Jia Ke to send troops, in fact, the two of them are still afraid in their hearts, and the war with the Tatars over the years, except for Jia Ke, no one else has ever won. They were afraid that Jia Ke would also fail and throw away the last fig leaf of the Central Plains Celestial Empire.

In the end, the three of them really couldn't argue with the result, and in the end they could only summarize their opinions and ask for a holy judgment.

After receiving Jia Ke's recital and the instructions of the three, the emperor was also in a dilemma. He has been beaten passively all these years, and he has hated the Tatars to the core, and he is of course happy that someone wants to go out and beat the Tatars. But what the other two college students said was also reasonable, if Jia Ke failed again, the loss of troops would be secondary. The main thing is how the people of the world will look at the Central Plains Celestial Empire.

The emperor took Jia Ke's recital, flipped through it and read it carefully, put it down after reading it, and then picked it up again, he felt very deeply about the sentence on it. That is: the enemy can go to me, and I can go.

The emperor was very touched by this sentence, and none of the many generals in his court had the courage of Jia Ke, let alone to defeat the Tatars in the steppe, even in a decisive battle with the enemy under the city.

The emperor once again watched Jia Ke's recital, clenched his fists and hung the imperial case. Finally, he picked up the red pen and commented on Jia Ke's recital: Allow to attack as appropriate, and take the preservation of yourself as the first.

After writing this sentence, the emperor thought for a long time, and added another sentence at the end: If you succeed, I will not hesitate to reward the marquis.

After the emperor approved this sentence, his heart was also much happier, and then he sent the fold and the horse out alone. Let Jia Ke prepare early.

When Jia Ke received the emperor's reply, it was already autumn. Jake thought that the Tatars were about to attack in all directions.

Jia Ke looked at the two lines of words on the fold: "Attack as appropriate, and take the preservation of yourself as the first." If it succeeds, I will not hesitate to reward the marquis. "My heart is like a fire, to say that he is not excited is false, and he is happy because he can get the opportunity to be a marquis. I am also happy that they went to the grassland to rob this time. If he succeeds in going north to the grassland this time, it will establish his status in the court in the future, and also make him a famous general in the world.

And Jia Ke thinks that this time the Northern Expedition has a good chance of success. The Tatars have repeatedly invaded the south, and they have never considered the safety of their lair, and this time they will definitely return with a full load. Now what awaits is the time, and when the Tatars have all invaded the south and are tripped everywhere, then it will be the time to attack the steppe themselves.
