In the construction of cavalry, Cao Liang has many mature ideas, such as the Takahashi saddle and bilateral stirrups that can greatly improve the combat effectiveness of the cavalry, such as the archer cavalry cultivated after the saddle and stirrup equipment and the heavy cavalry covered with full body armor.

As for the tactics of cavalry, in the twelfth and thirteenth centuries, they were brought to the extreme by the Mongols, and the cavalry of two thousand people could sweep across the entire Eurasian continent and create a miracle in the history of warfare.

But many ideas, Cao Liang can only think about it, at this stage, he doesn't dare to expose the high bridge saddle and bilateral stirrups, it is easy to arm a cavalry of seven hundred people, and it doesn't cost much, but this kind of thing is too easy to copy, as long as the other party takes a look, it can be easily imitated.

To put it bluntly, the Takahashi saddle and bilateral stirrups are a layer of window paper, as long as they are pierced, there is no secret at all, but the people of this era lack the spirit of scientific and technological research, and it is difficult to break through the inertial thinking.

The Takahashi saddle is just a piece of wood with a depression in the middle of the front and back, and the bilateral stirrups are just an addition to the unilateral stirrups, and there is not much technology in it. However, these two kinds of horse harness are the big killer weapons that really improve the combat effectiveness of the cavalry, and it was not until the end of the Wuhu and Sixteen Kingdoms that Xianbei officially equipped these two horse harnesses in the army, which also made the history of the Central Plains enter the Xianbei era.

If Cao Liang builds the Gaoqiao saddle and bilateral stirrups now, it is estimated that it will not take a few years to become popular all over the world, not to mention that the Sima family will plagiarize, and even Wuhu Zhuyi in the north will follow suit. The Hu people were originally stronger than the cavalry, and if they were allowed to get saddle stirrups again, it would be a nightmare for the people of the Central Plains, and even the tragedy of Wuhu Chaohua would be staged in advance.

Therefore, Cao Liang can only suppress the impulse in his heart, pinch out the idea of innovation and creation, and only think about it when the conditions are ripe in the future.

If you really want to cultivate a mature cavalry team, it is impossible to complete it without a year or two, so this matter is not urgent, and you can only follow the rules and follow the rules.

But fortunately, with Deng Ai and Shi Bao, the daily training of the Yue Cavalry Battalion does not need Cao Liang to worry about, after a few months, the training of the Yue Cavalry Battalion is basically on the right track, and the cavalry drill is also presentable, although I dare not say that it can be compared with the cavalry of the Xiao Cavalry Battalion, but at least in the eyes of the layman, there is not much difference.

However, Cao Liang knew in his heart that the current Yue Cavalry Battalion was only a vain appearance, and it would never be able to grow into a real cavalry team without real war experience, and the training of the Yue Cavalry Battalion had a long way to go.

In addition to his spare time, Cao Liang also went to Beibi Mountain a few times and met Ma Jun.

After experiencing the battle of Huainan, Cao Liang has some deep understanding of many military equipment, and this time he went to see Ma Jun, just to talk to Ma Jun about his understanding, hoping that Ma Jun can improve these weapons to improve the combat capability of the army.

Ma Jun was also happy about Cao Liang's arrival, among the civil and military officials of the Manchu Dynasty, although Cao Liang was not the first person to appreciate him, but he was the first person who really put his invention into practice, catapults and repeaters, but Ma Jun's life's brainchild, but because it was not recognized by the upper echelons, it was sealed in the corner.

Ma Jun even lamented that he may not see drawings turned into real objects in his lifetime, and as an inventor, this is the most regrettable thing.

Cao Liang's appearance made up for Ma Jun's regret, when he worked hard day and night to finally build the first catapult, Ma Jun was so excited that he burst into tears, and his long-cherished wish for many years was finally fulfilled, and this joy was indescribable.

Ma Jun is very grateful to Cao Liang from the bottom of his heart, without Cao Liang's help, his inventions would not have been born at all, and he was stillborn. It was with Cao Liang's full support and huge spending of money that this giant catapult came out, which fulfilled Ma Jun's wish for many years.

The arrival of Cao Liang this time has brought Ma Jun a lot of new ideas and inspiration, whether it is a siege vehicle, a rushing car, a catapult, or a bed crossbow, Cao Liang has put forward some targeted opinions according to practice, so that Ma Jun is like a treasure, write them down one by one, and then study and improve.

Although Cao Liang is not proficient in machinery, but in later generations also see a lot of things, the machinery of this era is crude and simple, and it cannot be compared with later generations, and many insights put forward by Cao Liang are indeed of epoch-making significance.

However, Cao Liang alone, although he understands what the principle is, and also understands that the gap is there, but he can't make it, and thanks to Ma Jun, a skilled craftsman, the two can work together to greatly improve the current mechanical level.

Cao Liang provided Ma Jun with manpower, funds, and sufficient raw materials, but all Ma Jun needed was to use his ingenuity and ingenuity to turn the things on the drawings into reality step by step.

Engaged in scientific and technological innovation, Cao Liang did not feel sorry for money at all, because he knew that any of Ma Jun's inventions was priceless, and with such a hard-working inventor working for him "free", Cao Liang was too late to be happy, so how could he deduct the appropriation to Ma Jun?

Human aggression is inseparable from invention and creation, sometimes Cao Liang secretly sighed, like Ma Jun, a top inventor, if placed in modern society, is enough to benefit thousands of people, but unfortunately born at the wrong time, even if he is ingenious, all inventions and creations can only be self-entertainment, can not produce any social value at all.

Cao Liang has great respect for Ma Jun, originally he wanted Ma Jun to move to Luoyang City, Cao Liang has already bought a house for him, with all the facilities, Ma Jun can move in directly.

But Ma Jun refused, saying that he was used to living in Beibi Mountain and didn't want to return to Luoyang City, which was full of turbidity, so Cao Liang sent someone to renovate the house for him, and moved all the experimental items that Ma Jun needed up the mountain, and also arranged a number of apprentices to give Ma Jun a start, and also serve Ma Jun, after all, Ma Jun is very old, and there are few people around him to take care of him, so that's not good.

Ma Jun was deeply moved by Cao Liang's kindness and resigned, but Cao Liang insisted on his own approach.

Joke, Ma Jun is one of the few talents in the invention world, now that he is old and precarious, Cao Liang has not lost an inventor because of this, so he will take care of him in all aspects.
