When Zhao Yu first came to this world, he also thought that a soldier should maintain a strong body, not to mention that all of them are bodybuilding champions, nor can they be a bloated figure with a stomach, thinking that such a soldier does not talk about fighting, even if he is afraid that the march will drag down his comrades. Therefore, he once demanded that the generals should exercise regularly and control their weight, and even planned to set a weight standard with reference to the standards of the modern US military, and those who exceeded the standard would be forced to retire.

However, after a while, Zhao Hao felt that his idea was wrong. First of all, modern fighting is fought by weighing weights. In order to be fair, there are many weight classes, and you need to weigh yourself before the fight to decide what weight you play. Therefore, in order to avoid people who are one order of magnitude higher than themselves from losing weight by surprise and fighting with themselves, fighters will suddenly lose weight before the game and fight one or even two orders of magnitude lower than their natural weight. Since everyone is desperately trying to lose weight when they are approaching the competition, most of the fighters we see are naturally the image of eight-pack abs without fat.

Because if you want your abdominal muscles to have a clear shape, you don't need to train big muscles, but to have a low body fat percentage. And everyone actually has abs, as long as they are thin enough, they can see the contour of abs. This is also the case for the actors with eight-pack abs in film and television works, who lose weight in order to look good before filming, and it is difficult to maintain the image of eight-pack abs when they are not filming, and they accidentally become potbellies when they are not filming.

And after participating in military affairs, Zhao Hao quickly understood that it is not easy for a soldier to gain weight, not only does he sleep in the open during the war, but he doesn't even have time to eat when he is nervous, and he has to go hungry if he catches up with the logistics supply; In peacetime, even if there is no combat mission, if you are well fed and warmly dressed, you need to carry out a lot of physical training, and what you eat is not big fish and meat every day, and it is good to eat enough. It's very difficult to accumulate a little bit of fat like this.

In addition, from a physiological point of view, it is normal for humans to store a little fat in their abdomen. Because there is a part of fat that plays an important role in fighting cold and food scarcity. The existence of fat is the result of human evolution, and growing fat is actually engraved in everyone's DNA. At the same time, in this era without the assistance of modern machinery, soldiers also have to bear heavy physical labor, and it is an extremely physically demanding exercise when fighting and fighting. If you don't have the weight to support, how can you open a hard bow, dance a heavy weapon, lift the bolt of the city gate, and overturn the war horse.

In the case of such a huge amount of exercise consumption on the battlefield, fat can help the generals maintain a positive nitrogen balance and physical strength for a long time. If it is a macho man with eight-pack abs, although the muscles are very good-looking, but in the environment of long-term and high-intensity combat on the battlefield, he may not last for a few days, and his physical fitness will not be enough. Because people need energy for exercise, after the stored glycogen is consumed, there is no fat to decompose and provide energy, so naturally there is no physical strength to continue fighting.

In addition, fat also has a life-saving effect, which can provide a cushion against blows when receiving a heavy blow, and can effectively absorb kinetic energy. In the case of wearing armor and armor, in the case of blunt force blows, there is not even injury with fat. In addition, even in the face of a sharp blade, there is a possibility that the fat will not be disabled because the skin is too thin, causing the blade to directly cut off the muscles and bones. Therefore, fat can increase survivability, and the ancient military generals can have greater vitality after being injured.

But those good-looking muscles, such as pectoralis major, rectus abdominis, deltoids, biceps. These muscles are concentrated on the front of the human body, which is more beautiful, but in fact, they are not very useful for martial arts. And the most important for the effect of opening the bow, spear stabbing, and punching is the latissimus dorsi, which grows behind the body, and can not be seen no matter how big the practice is. Another example is the pectoralis major muscle, which makes people look stronger, and if it is practiced too much, it can even become an obstacle to punching.

In addition, although the thin man is said to be flexible, his short-distance explosive power is actually far inferior to the Roshan-type fighter with a big waist and a round waist. The lack of octapack abs is not because his abs have degenerated, but simply because his body fat percentage has increased and the shape of his abs is not obvious. The muscles are still there, just an extra layer of fat. So will this affect his combat effectiveness? Obviously, this thin layer of fat is unlikely to affect the waist and abdomen, and the biggest negative impact of an extra layer of fat is that it is not as good-looking as an eight-pack abs.

Not to mention that the weight gain caused by fat is actually not a bad thing in combat, because when wearing heavy armor, you may not be able to cut the opponent at all with a knife, but it is very effective to fall down the opponent at close range and then stab the crack in the armor. In this regard, the weight of fat can effectively make it difficult for opponents to fall down, while thin people will be grabbed by fierce generals and used as weapons. For example, Dian Wei picked up two enemy soldiers before he died in battle and killed them on the spot. In other words, fat and fat are sometimes very necessary, at least they will not be caught by opponents!

Zhao Hao, who figured it out, adjusted the standard of weight after that, as long as it was not fat and couldn't walk, it was within the range of tolerance, and adjusted the standard of food expenses, striving to feed the soldiers fatter. But he doesn't know if what he did is completely right, after all, the current army has changed its combat mode after changing to muskets, it is no longer a simple physical competition, and it can only cross the river by feeling the stones, in any case, it is also difficult to create an army with obesity in this era when you can eat well and be happy.

"The whole team!" After coming out of the formation, Zhao Hao ordered to regroup the team and prepare for another battle!

The heralds blew their trumpets and ordered the flags to shake again and again, and the various units that rushed out of the battle formation immediately moved to the imperial flag when they heard the order, and gathered under their own military flags during the movement. Zhao Yu looked at the guard battalion that had just regrouped around him, all of them were also blood-stained robes, and there were vacancies in the queue, which were uneven, but they were basically still intact. But the other divisions were not so lucky, there were large casualties, some of them were only half of the group, and some of them lost their horses, but they still stood in the queue.

"The wounded and horseless will be removed from the queue and will be on standby after returning to the formation!" Zhao Yu sighed secretly in his heart and said loudly. He knew that the guard battalion was the elite of the Song army, all of whom were warriors who had survived a hundred battles, and it was common sense that they had rich combat experience and small casualties. However, the cavalry under the corps and divisions is not only small, but generally only performs the tasks of vigilance, ordering, and reconnaissance, and encounters with the enemy's cavalry are quickly avoided, and large-scale battles with the enemy rarely occur face to face. But this time it was a real hard battle, and the opponent was the invincible heavy cavalry in the Mengyuan army, and it was inevitable that he would fall behind.

"Yes!" The officers of the various units responded in unison, immediately reorganized the ranks, separated the wounded from the ranks, assigned the horses to those soldiers who could still fight without horses, combined the detachments with heavier casualties, and arranged for the accompanying medics to bandage the wounded and retreat.

Zhao Yu looked at the wounded soldiers who had been separated, most of their injuries were slashed, which was very easy to distinguish. The Song army had abandoned leather armor and iron armor and converted it into cuirass and back armor similar to modern bulletproof vests, with leather or densely woven thick linen cloth as the table, and porcelain tiles inserted into the armor, but the helmet was still an iron helmet, which could provide good protection for the torso, neck and head. The porcelain shards in the breastplates or dorsal armor of these wounded soldiers were visibly shattered, and cracks appeared in their helmets, which made them look very terrifying. Obviously, only a slash can cause such severe damage to the armor, and the power of the stab cannot do it.

"Did I make the wrong choice?" Zhao Hao frowned and said darkly. When he first formed the cavalry, it was only after a long period of consideration that he decided to use muskets and sabers as weapons. However, the cavalry knife chosen was not the ring-headed knife and scimitar, which are very popular at the moment, but the 'straight sword' that only appeared in the West in modern times. However, he also improved it, only cutting it on one side, and still retaining the heavy back of the knife on one side so as not to break in battle. On the whole, the knife shape is slender and sharp, and it can be seen from the shape that this riding knife is conducive to stabbing, although it can also be chopped, but it is obviously only an auxiliary.

In this way, Zhao Yu felt that the killing method of the stab was a straight line attack, relying on deep killing, basically the middle one would die, and it was conducive to armor penetration; The slash is a lateral attack, relying on sharpness to kill. The different killing methods also determine that they face different targets and have different lethality. Generally speaking, for an attack on the torso, the thrust is more lethal than the slash at the same force. The reason is that the spike is a straight line attack and can injure internal organs; Slashing is a lateral attack, and it is difficult to hurt the internal organs with one blow.

However, going into battle in person today, Zhao Yu also realized that for some fierce people, the slash of the torso is also fatal. During the battle, he saw an enemy soldier standing on a stirrup and slashing at him, cutting off one of his cavalrymen. Of course, in addition to its superior force, another important reason for this is that both sides are in the stage of high-speed hedging at this time, and it is not surprising that with the momentum of two horses, this effect is not surprising.

And Zhao Yu found that the attack on the head and face of the slash was greater than the thrust under the same strength, and even if there was helmet protection, there was a way to inflict fatal damage. He analyzed that because the bones in the head were hard enough and on the outermost part, the spike was blocked in the first step. And slashing kills by sharpness, and there is no place in the human body that can withstand the sharp blade.

In fact, when Zhao Yu faced three enemy cavalry, he could easily pierce the throat of one enemy soldier with his riding knife, but he could only smash the palatal bone of the other enemy soldier. Although he used the back of his sword, he thought that even if he used the blade, he might not be able to see through the curtain of the enemy horseman's helmet and take off his head. However, in the melee, he also saw that his own soldiers were covered with knife marks, and the head of one of the soldiers' corpses was chopped off, and the opponent's war knife was directly slashed from the top of his head to his eyes; The other man was lying on the ground, the blade of the knife slashed from the top of his head to his nose, his face was split in half from his nose, his brain was leaking out, and the whole brain cavity was completely empty.

Of course, their own spurs also made Meng Yuan heavy cavalry suffer from stabs, and the route of their attack was full of dead and wounded enemy soldiers, and a stab in the high-speed charge was enough to inflict heavy damage on them, causing fatal injuries, and most of them died on the spot. The wounds left on their limbs, if not fatal, can cause a lot of blood loss, which can make them lose the ability to continue fighting.

In a parity situation, their side still suffered heavy casualties, and at least one-third of them withdrew from the battle. Zhao Yu analyzed that in fact, whether it is a stab or a chop, there is no superiority or inferiority, only a more suitable situation, and the casualties of his own side are mainly caused by a lack of actual combat experience.

Because in a melee, the human instinct is to chop. So when the belligerents enter into a white-hot white-knives battle, human instinct prevails, and although you have been taught to thrust with the tip of your sword, in battle it is to slash at each other; In addition, there is the psychological effect, although the thrust on the torso is fatal, but the main injury is internal bleeding, which is not too serious from the outside. But for slashing the head, face and torso, even if it is not fatal, the scars are shocking enough, which will have a deterrent effect on the psyche and reduce morale.

However, Zhao Yu was also pleased to find that the inconspicuous small round shield in the cavalry equipment shone in the battle just now. This round shield is much smaller than the shield used by the infantry, and its diameter is only one and a half feet, and it can be hung directly around the waist without affecting any movement when not in use. The shield is made entirely of forged pieces, which can easily withstand the damage of enemy swords. There is a circular protrusion in the middle, which can be used by holding the bar behind the bulge or by tying it to the forearm.

Of course, because the area is too small, it is not effective against long-range weapons such as bows and arrows, and its true value is reflected in hand-to-hand combat. When fighting, the main purpose of this shield is to protect the arm, and you can also easily push the opponent's sword outward, or use the middle bulge to slam into the enemy, especially the face, even if you can't knock it down, you can also give it a heavy blow, Zhao Yu used the round shield to easily smash an enemy soldier off the horse. It's not an exaggeration to call it a battlefield companion in hand-to-hand combat.

"Array!" Although he thought about it a lot, it didn't take long, and the well-trained Song army had already sorted it out in a moment. At this time, although the Mengyuan enemy cavalry was rushed through a gap by their own side, causing chaos, the enemy soldiers who left the city quickly filled the gap, and rushed towards their own defense line after a little rectification, and the rearranged defense line of their own infantry army had not yet been completed. He ordered the formation to be put in shape and again charged the enemy cavalry that had broken through.

"Assault!" Under the command of the battle flag and military horn, the cavalry of the Song army quickly discharged a wide formation with more than 100 cavalry as a horizontal formation and six columns in depth......
