The military exercise of the Great Song Dynasty ended early, and the original three-month training plan was reduced to two months, but it was the same for Di Qing and Peng Qi, their purpose had been achieved, and only Peng Qi, Di Qing, and Xia Zhu knew the purpose of the military exercise from now on.

The first is to familiarize the army with the environment in the north, and the second is to paralyze the Liao and party members.

The army came and retreated quickly, and there were cement roads on the land near the Song-Liao border in the Great Song Dynasty, which made the army of the Great Song Dynasty come and go like the wind, and the wide carriages could quickly transport soldiers, and there were cavalry troops on the side, so there was basically no need to worry about the safety of the army.

With the transportation of horse-drawn carriages, soldiers can rush to the battlefield or withdraw to the hinterland without stopping, the speed and time have reached an amazing point, from the Zhending Mansion to Tokyo City, it used to take half a month or even a month, but now it is withdrawn in just five days, and even faster!

The most important thing that this military exercise brought to the Great Song Dynasty was the experience of marching, how to send the soldiers to the battlefield quickly and well, how to maintain the maximum combat effectiveness of the soldiers, and so on, all of which could not be bought with money.

The importance of the military exercise was highlighted at once, and the civil and military officials of the DPRK and the central government discovered the benefits of the military exercise, and the voice of opposition quietly disappeared, although the civil servants were not good at military affairs, but they were not stupid, the cost of the military exercise was not as much as expected, and the expected purpose was achieved, and it was a good thing to have gains.

The combat effectiveness of the cavalry was reflected at once, and some officials who originally insisted on riding on foot also saw the importance of cavalry, and the lack of war horses before the Great Song Dynasty was not suitable for large-scale development of cavalry, but now that there are excellent war horses, what reason is there not to form a strong cavalry unit?

Back to the back, the Second Army of Tabai was put in the first place.

What the Great Song gained from this military exercise was far greater than the killing of Yelu Dadan.

Zhao Zhen looked at the elite soldiers who were rushing in and nodded slightly, this is the soldier of the Great Song Dynasty, and then he can focus on solving the problems found, although the effect of this military exercise is ideal, there are many problems that can be exposed.

For example, the problem of military food supply is very headache, the Great Song Dynasty still uses fried noodles as military food, Zhao Zhen has planned to experiment with a new batch of military food, such as compressed biscuits and the like, although the packaging is a problem, the advantages of compressible biscuits are much more than fried noodles, which are nutritious and delicious, and easy to store, the key is not to occupy space.

Cai Ji has begun to undertake this kind of compressed biscuits, and it should not be a big problem for Cai Boyu to supervise the foodie, and Zhao Zhen, as the king of a country, personally inspected Cai Ji not once or twice, Cai Boyu bowed and led Zhao Zhen to the water workshop.

The flames licked the cauldron, the fragrant wheat was stir-fried and more fragrant, the white frosting, the delicate fat, and the dried milk that had been slightly yellow were put into it and stir-fried and fried, a unique fragrance emanated so that Zhao Zhen, who had tasted all the food of the Great Song Dynasty, couldn't help but swallow his saliva.

Cai Boyu grabbed a handful of dried fruits and put them into it, which is considered to be done, and then it is the most important process, the water-powered instrument can easily press the raw materials into squares, because water is used as the power, so this process has to be repeatedly squeezed to eliminate water.

The old wooden tools had been crushed, and now it was much better to replace them with clean iron molds.

Zhao Zhen stretched out his hand to pick up a piece of compressed military ration, and almost broke his teeth in one bite, which was too hard, and looked at Cai Boyu's eyes a little unkindly: "How can this soldier eat this?" ”

Cai Boyu bowed and said, "Your Majesty will demonstrate later." ”

Cai Boyu took a large piece of military ration from Zhao Zhen's hand, cut off a piece with a knife and put it in Zhao Zhen's hand and said, "Please taste it again, Your Majesty." ”

Small pieces of compressed ration are placed in the mouth, and after being moistened by saliva, they quickly become soft, and the unique aroma of the flour is mixed with various spices to achieve the perfect ratio, and there is a hint of saltiness, which is to replenish the salt needed by the soldiers.

After eating two small pieces, Zhao Zhen took a sip of water, and soon felt that his stomach was full, and his original hunger was gone!

Unexpectedly, Cai Boyu really made a compressed military ration according to his own requirements, which solved the food supply problem of the Great Song Dynasty army, of course, this kind of military ration will only be used for marching, once stationed, it is still necessary to use traditional food.

After all, the army is outside, and you can't even eat a mouthful of hot food, which not only affects the body, but also affects your mood and combat effectiveness.

Zhao Zhen turned his head to Cai Boyan and said: "It can only be the same, do you feel a little wronged now, everything you have done for the Great Song Dynasty can make you become an official and a knight, but it's a pity that your status as a colt is ......"

Cai Boyu shook his head and said: "The official family is serious, Cai Boyu feels that his life is very good now, he can not only contribute to the Great Song Dynasty, but also do not have to mix with the affairs of the court, and the most important thing is that no matter how I toss, it is useless to ask me to ...... by the standards of scholars."

Zhao Zhen pointed to Cai Boyu's slightly chubby cheeks: "You live an easy life, but your face has become fat since you returned to the Great Song Dynasty." ”

Cai Boyu laughed twice and hurriedly led the topic elsewhere: "Do you want the official family to see Cai Ji's carriage?" This is specially designed by the minister for the soldiers of the Great Song Dynasty, and he asked His Majesty not to laugh at it behind closed doors. ”

Zhao Zhen looked at Cai Boyu in surprise, what's wrong with this kid, why is he suddenly so concerned about armaments? It was quite difficult for him to accept the iron ore of the Great Song Dynasty before, so he turned his head and smiled: "Why do you plan to contribute to the country?" ”

Cai Boyu shook his head and said with a smile: "Can the armaments of the Great Song Dynasty be handed over to Cai Ji to share a part?" After all, it is difficult for the Ordnance Department and the Armament Department to produce these artifacts on a large scale, and they are already overwhelmed by the plate armor and blades alone, if Cai Ji can afford military rations and vehicles, etc., it can save the cost of the imperial court, right? ”

This kid is to fight the business to the military quarters, yes, after all, the military supplies of the Great Song Dynasty are very large, and the interests are also entangled in a lot, and the annual apportionment to the merchants will cost a lot of money for the collection of materials, etc., but if Cai Ji is given the exclusive operation, it is also a very good choice.

At least he Cai Ji is under his control, and he can block many transactions that are invisible to the court, and he can also pursue responsibility to the greatest extent......

Today's Cai Ji is a behemoth in the Great Song Dynasty, and it is good to hand over unimportant military supplies to Cai Ji, after all, Cai Ji and the merchants of the Great Song Dynasty cooperate quite closely, and they can also drive the development of some businesses.

When Zhao Zhen saw the carriage designed by Cai Boyu, he was speechless in surprise, what kind of carriage is this, it is simply a slaughtering tool on the battlefield, and the chariot, a luxury weapon that requires a large number of horses, is basically impossible for the Great Song Dynasty, which originally lacked war horses, but now it is different.

With powerful Arabian war horses, Zhao Zhen believed that these chariots, armed to the teeth, could kill and injure the enemy to the greatest extent.

The main enemies of the Great Song Dynasty were all cavalry combat, so the chariots designed by Cai Boyu were mainly aimed at cavalry, focusing on defense, and killing and injuring cavalry to the greatest extent while defending.

Therefore, these chariots were basically armed to various places, and even the carriages were made of solid iron sheets, but the weight was about the same as ordinary wooden carriages, which was the advanced performance of the forging iron technology of the Great Song Dynasty.

Zhao Zhen gently stroked the surface, the outermost is not an iron skin but a cow skin, Tufan's cattle consumption is the main source of Da Song beef, and its skin has also been retained for military use.

Zhao Zhen really didn't know what else needed to be improved in such a chariot, the terrifying degree of the hideous thorns protruding from the axle was completely a sharp weapon against the cavalry, and the carriage was also a type that could be opened and closed from the top, once the chariot rushed into the enemy formation, it had its own armor to attack it.

The most important thing is that the front wheels of such a chariot are movable, and not extremely laborious to rotate like ordinary carriages, and under the control of the coachman, the carriage is not at all bulky to move.

What kind of situation it would be like for such a chariot to rush into the enemy formation, Zhao Zhen didn't dare to imagine, it was really inhumane......
