A war of attrition is underway.

The werewolf of the mysterious wizard's transformation chased after him, without using any auxiliary spells, but the advantage of his body alone allowed him to burst out with a speed far beyond ordinary people for a long time. But instead of directly catching up with Richard and attacking, he hung behind Richard, as if he was going to use this way to consume Richard alive and let Richard be killed in despair.

Richard ran in front, and kept running. There are multiple layers of "light wind spirit" on the body, making all kinds of unreasonable actions, crossing the obstacles in the forest below the hill to the limit, and gradually narrowing the distance between the mysterious wizard and the werewolf.

After maintaining this high speed for a moment, Richard began to take deep breaths while sweating, but the speed remained the same.

At this time, Richard did not have much fear in his heart, and if there were no accidents, he could keep this run going forever. If the mysterious wizard dares to return to the human body all the time, Richard is confident that in this war of attrition, the werewolf that the mysterious wizard has turned into will fall to the ground first, or even run away.

Reason, no other, because ...... Humans are the world's most capable long-distance runners.

Short toes, slender legs, elastic tendons, well-developed gluteal muscles, flexible and slender waist with subtle twists, arm swings that help balance the center of gravity when stepping out of the legs, well-developed neck ligaments on the head when running steadily, and ultra-high fat content that provides energy supply. Everything forms the basis of the most powerful body suitable for a robe.

In addition, heat dissipation and breathing, as two golden advantages, make humans far superior to all living beings except humans. All creatures!

First, heat dissipation. Heat dissipation is the main obstacle to long-distance running, and heat dissipation is divided into body heat dissipation and brain heat dissipation.

For body heat dissipation, human skin can sweat 500g per hour per square meter, which is 2 times that of camels and 5 times that of horses, and the well-developed skin sweat glands make the body cool down quickly;

For brain heat dissipation, the human intracranial venous system is well developed, and countless small holes are opened in the skull, so that the blood can flow out of the brain and into the subcutaneous area, so that the brain can be quickly cooled.

For the rest of the animals, in terms of body heat dissipation, most of the sweat glands are not comparable to humans, and they do not use sweating as the main way to dissipate heat, and the cooling is very slow. For example, dogs gasp and stick out their tongues (using the end of the breath to breathe with sweat glands in the mouth), cats add sweat glands to the soles of their feet, monkeys wag their tails (there are veins in their tails), and elephants and rabbits shake their ears (the ears have a rich network of capillaries).

These heat dissipations simply cannot sustain long-term high-speed movements. On the modern earth, someone asked the cheetah to step on the treadmill and found that although the speed of the cheetah on the treadmill was far from reaching the maximum speed of 110km/h, the body temperature was soaring, and once the body temperature reached 40 degrees, the cheetah said that it would not move anything.

In the rest of the animals, in terms of brain heat dissipation, the intracranial venous system is similar to that of humans, all of which enter the spine from the skull and then into the lungs. However, because there is no skull hole, the brain cools down slowly, and once it starts running at high speed, it cannot dissipate the heat in time, and the speed must be reduced, otherwise it will lead to brain death. For example, if a horse keeps running at a normal speed and dies, it is likely that the cause is brain overheating.

Second, breathe. Without breathing, there is no life, and naturally there is no running. Breathing, on the other hand, generally includes two elements: frequency and depth.

The advantage of human respiration is that when the oxygen consumption of high-speed exercise increases, it can independently strengthen and deepen breathing and increase the oxygen supply, and if necessary, it can also open its mouth and use the oral cavity to inhale oxygen.

The disadvantages of other animals are: animals are passive breathing, breathing frequency, depth, completely rely on limb movements to drive the expansion and contraction of the chest cavity, they can not breathe through the mouth, can only use the nose. And the larger the body size and the longer the nasal cavity, the less efficient it is. When you can't meet the oxygen supply when you run, you can only reduce your speed to reduce your oxygen consumption, or you will die. For example, if a horse dies in a high-speed run, one possibility is a comprehensive death caused by insufficient blood and oxygen - poisoning + stroke.

There is no doubt that humans are the most capable long-distance runners in the world.

Purely comparing combat effectiveness, human beings are far from being the opponents of leopards, wolves, tigers, lions and other fierce beasts, and in terms of the speed of outbreaks, they are not comparable to wild horses, antelopes, and wild boars. However, in the era of fishing and hunting, human ancestors acted in groups of three or five, often dozens or even hundreds of people hunting. One man with a spear in his hand, shouting, chasing, forcing the beast to flee desperately in one direction.

And the beast ...... There is no escape!

Heat dissipation and breathing, locked to the "neck" of each beast, like a shackle of death. No matter how fast the leopard is, it will have to stop in a few minutes, and no matter how strong the wolf, lion and tiger are, it will be paralyzed in ten minutes. Even vegetarian animals such as antelopes and wild horses with strong endurance rarely run for more than an hour.

By the time these beasts ran desperately until they were hungry and thirsty, and when they stopped in place to gasp, rest, and find a way to eat, the human ancestors had followed their escape tracks, the feces they left behind, and chased them with dry food and weapons. Maybe it's been chasing for hours, maybe it's been a whole day, but the result is decided from the beginning, it was the Creator who decided at the time of creation.

This is how the ancestors of mankind developed! They relied not only on the wisdom of making weapons and cooperating with each other, but also on the strength of their bodies and their animal nature that surpassed all living things!

In ancient times, humans were the kings of all beasts!

The king of beasts, beasts of prey, dominate the forest!

The king of beasts, humans, hunt everything!

As for under normal circumstances, human beings often find it difficult to do all this, and then have doubts, all because of the environment they live in, the so-called wisdom, and the constraints of willpower. It's like a pet cat raised in a room, which can be scared by mice. In fact, this cat is no different from the cat that hunts mice in the countryside in terms of physical structure and physiological mechanism.

In a sense, many people are pet people who have been raised by the advanced survival mode of society. If you dare to get out of this mode, you will be able to recover the lost instinct and have incredible abilities.

On the modern earth, many people are engaged in this kind of challenge, and the best proof is the limit record:

42.195km full marathon, men's record 2 hours, 2 minutes 57 seconds, women's record 2 hours, 15 minutes 25 seconds;

100km Ma Super Lasong, men's record 6 hours, 13 minutes 33 seconds, women's record 6 hours, 33 minutes 11 seconds;

a 100-mile (160 km) ultramarathon with a record of 11 hours, 40 minutes and 55 seconds;

135-mile (217 km) Dead Valley Bad Water Ultramarathon, California, USA, recorded 25 hours, 41 minutes and 18 seconds;

246km Spartan Ultramarathon, men's record 26 hours, 28 minutes and 19 seconds, women's record 27 hours, 2 minutes and 17 seconds;

875km Sydney to Melbourne Marathon, recorded 5 days at 15 hours and 4 minutes;

For Richard, the mysterious wizard turned into a werewolf, and what he got was not the advantage of the wolf, but the disadvantage of the wolf. The more ingredients that change into wolves, the greater the disadvantage you get.

And as a human being, before he came to this world inexplicably, he has been consciously exercising his body for more than ten years without obtaining the ability of spells. Of course, because of the constraints of the conditions, it is impossible to reach the peak state of human beings. And after he started to study spells, his training was also slack, but after all, he was confident that he would consume the werewolf of the mysterious wizard to death.

Of course, this is on the premise that the other party is really stupid enough to keep running like this and will not make any changes.

So will the other party?

Richard jumped over a rock in the forest and looked behind him.
