Chapter 4 (2/2)

There was a lot of discussion among these young boys, but children are children. Even if they are more mature, there is still a childish air between their words and behaviors.

At the beginning of the formal discussion, it soon turned crooked, until Marshall coughed heavily, then blinked and blinked, trying to restore the formal appearance. However, they still exchanged glances and continued the debate with their eyes.

Compared with Sean, who smiles all day and rarely gets angry, Marshall, who has a poker face all day, is the one most afraid of this group of children.Sean's work did not stop, only in some important places will stop to explain.

There are many similarities between the medieval world and the previous one. Most of the physical laws are the same, such as gravity, friction, acceleration, and so on. Even the body structure of most creatures is similar.

At least the appearance is not very different, but there are differences in many details, such as the size of wildlife is one or two larger than previous generations.

For another example, the muscle strip like the present is not found in previous generations. Sean calls this muscle strip the reinforced leather muscle, or leather muscle for short. It is an enhanced version of muscle, with a more compact and complex inner structure than muscle.

This makes it as tough and tough as leather, five times more explosive than ordinary muscle, and it also has a unique ability - energy storage.

It has more powerful energy storage function than fat. The energy stored in a leather muscle of the same weight is equal to the energy produced by burning ten times the weight of fat.

The most important thing is that the energy stored in the leather muscle can be directly used by the body without the need to switch back and forth.

There is no need to say much about the effect of leather muscle. This is a piece of natural military food. The energy provided by three or two layers of leather muscle is enough to maintain Sean's high-intensity hunting all day. If the leather muscle is added to the training meal, it will achieve twice the result with half the effort. It is easier to exercise the leather muscle. It is reasonable to eat what you eat to make up for what you eat under certain circumstances.

However, the quantity of leather muscle is obviously proportional to its value. It is a strengthened version of muscle, not a strengthened version of fat. It can only be produced under certain intensity of exercise or training. On livestock with little exercise, it is very rare. A strong bull can pick out half a catty as much.

Wild animals with a large amount of exercise are obviously stronger, and the leather muscles of the hunters are obviously more than those of the hunted, but they are still relatively limited. After all, no matter how smart a hunter is, he will not deliberately exercise his leather muscles like a man.

Just like this Andes bear, the rich food sources around it make its exercise capacity relatively limited. Although it has the outstanding body shape of its kind, the number of leather muscles in the body is average, mainly concentrated in the limbs and head, and can pick out 10 kg, even if they are lucky.

Ten kilograms looks like a lot, but on a 3000 pound behemoth, the output ratio is obvious.

Besides the leather muscle, there are also leather tendons and leather bones.

Different from the leather muscle, there is no way to separate the leather tendon and tendon ligament. They are entangled and fused together. All biological tendons and ligaments are more or less leather tendon. The difference is that the proportion of leather tendon in them can reach more than 70%. Only one kind of biological body - Human, but also a knight after systematic and rigorous training Go ahead.

This Andes bear has about 60% of its leather tendons. The most important thing is that the skin muscles on its limbs are long enough, especially those from its hind legs, which are more than three meters long.

After special methods of removing impurities and tanning, although the weight of the wire rope is only one third of that of the same thickness, the bearing capacity is three times of that of the steel wire rope, and the toughness is ten times as much. It is the best material for strong bows and crossbows.

The archery bow made of leather tendon of the hind legs of Andes giant bear is the biggest dream of every Andes mountain hunter. This super strong bow is said to easily shoot down mountain eagles flying hundreds of feet in the sky. It is the standard configuration of every archer. Without a shooting bow, you can't become a shooter.

is a hunter who can shoot down the eagle eagle in the mountain. If the bow does not give strength, even if you have the exquisite archery, it will suck.

Sean also had a long craving for this excellent bow and arrow material. Even the matching bow and crossbow were suppressed two years ago. Unfortunately, the Andes bear is not as stupid as it looks, and its big hair depends on the situation.

If it had not been for the sound of a bow, it would never rush forward. In the course of the charge, Sean was not alone, and it was likely to turn to escape temporarily.

Compared with the undas bear in good condition, even the hounds are willing to fall behind, which is the reason why Sean put the hounds in a distance. However, the cunning Andes bear still sensed the breath of children on the ridge and nearly failed.

……

The long haired Hound is a typical guard and bird catcher, between medium-sized dogs and large dogs. Its night vision is the strongest among the three kinds of dogs. They usually rest in the day and the first half of the night. The second half of the night is when they are most energetic. It is difficult for hunters to escape the dual detection network composed of vision and smell. Their strong sense of responsibility makes them even in the face of death threats They seldom leave their posts. Among Andes mountain people, there are many living examples of long haired hounds that do not hesitate to use themselves as bait to lure away enemies and save their owners. Their slender body and strong hind legs give them more flexible turning and jumping abilities. Hunting birds flying at low altitude is their specialty.
