"296, 297, 298, 299, 300, good! Yang Tianyue, you have made progress again this time, which is worthy of praise. Yang Wenli stood aside to help Yang Tianyue count and praised him.

Don't think that doing 300 push-ups is very simple, in fact, the difficulty of push-ups and upside up has a lot to do with your own weight, a lean person may be very easy to do 300 push-ups, but if you want to do 300 push-ups with a lot of weight, it is very difficult, just like a person can easily lift dozens of pounds, but it is difficult to lift 150 pounds.

Yang Tianyue, who is only twelve years old, weighs more than fifty kilograms, and it has not been in vain in the past few years, and all ten of them have become big men.

Of course, the main reason is that they are all thick and tall, and after all these years of training, they are naturally different from ordinary people.

"Huh!" Yang Tianyue stood up and smiled. Yang Wenli has been training with them for a long time, and it can be said that he is their mentor and friend, and every teenager is proud to be praised by him.

"Bang Bang!" Yang Wenli clapped his palms, attracting the attention of the other teenagers who were still exercising, and then began to say, "Very good! After several years of training, your strength and physical fitness have basically reached my initial requirements, and in the future, as long as you continue to practice, you will definitely have the strength of the ancient famous generals.

From today onwards, you will begin to practice the official battlefield killing moves: splitting, teasing, and slashing, and each of you will prepare a miscellaneous wooden stick about three feet long, and the part you hold with one hand will be sharpened to fit your grip.

Tell you a trick, the move can't be used old, cut off the big open and close, on the battlefield, victory and defeat are often in an instant, so we must be as fast as possible, and if we miss, we will immediately change to flirt and fight for ourselves.

If the move is too old, there will definitely be a slight pause, and at that point you may be killed by the enemy. There is a difference between the military and the individual, and we must keep it in mind.

As long as you are fast enough, you don't need to make a second move, so your next time is to practice the three tricks of splitting and cutting, so that each move is fast to the peak, exceeding the speed of human reaction ,......"

The normal human nerve transmission speed is about 100 meters per second, and then the more muscles, the more responsive they are

Many psychologists have measured more than 0.1s in their experiments on people's physiological responses

But everyone's is different.

Reaction time and the state and mood of the person have a lot to do with it.

Generally, when you are in a good mood, you react faster than when you are in a bad mood.

Reacting faster when you're excited than when you're frustrated.

For example, the reaction time of a person who does not wake up or drinks alcohol will be greatly prolonged, about 1 second

The reaction time of a normal person is 0.15 seconds to 0.4 seconds

As can be seen from the above, as long as the attack speed exceeds 0.15 seconds, ordinary people will only be slaughtered.

Bruce Lee, a famous martial arts master, has a speed of nine times per second, which is 0.11 seconds, which exceeds the reaction speed of ordinary people, so he can be invincible.

In fact, miscellaneous wooden sticks are a substitute for knives, yes, Yang Wenli only needs his subordinates to practice knives. Originally, the gun was the king of ten thousand soldiers, and it was necessary to practice the gun to kill the enemy on the battlefield, but Yang Wenli would let them practice archery in the future and train them to become archers, in fact, there were very few opportunities for hand-to-hand combat, so it was impossible to carry a long gun with him, but the knife was the most suitable.

Yang Wenli's favorite thing in the gym in his previous life was archery, and over time, he can basically be called an archer with no missing arrows, and he knows the principle of making bows and arrows well, which can be said to be his capital to be reborn in this troubled world!

He didn't read much, on the contrary, he didn't know anything about the principles of gunpowder muskets, and he was much inferior to the natives of this world.

In the Ming Dynasty, there was an influx of Western muskets, and the army had used muskets in large quantities, but they had no advantage in range, and they were easy to explode, killing 100 enemies and injuring 3,000 themselves.

In some respects, muskets are not as good as ancient bows and arrows, so it is impossible for him to line up with muskets and shoot them, and it is the most correct to be his best.

Of course, the longest-range and smallest compound bow is the most suitable. The compound bow has a long production cycle and the most demanding material selection, which is several levels more difficult to make than the English longbow.

But its advantages are also obvious, suitable for personal carrying and use, and also suitable for archery on horseback. The English longbow can only be used in battle formations, its rapid attack accuracy is not high, the only advantage is that it has a long range, and it must be used by people with tall physiques and long arms and arms, which is not suitable for the Asian race.

There is a lot of scientific and technological content in making bows and arrows, and there are a lot of information summaries in modern times, and in ancient times, it was passed down orally by traditional craftsmen, and it was known but not known, so it is unceremonious to say that Yang Wenli is definitely the best bow master in the world.

The first is the selection of materials, the best bow material for bows and arrows is firewood and fir wood, followed by mulberry, elm, Zhemu, etc., and its main technical indicator is energy storage density.

These materials have been practiced for a long time by the major bow-making families in later countries. Here, Yang Wenli easily chose wood and fir wood.

In fact, as early as a few years ago, Yang Wenli had already stockpiled a large number of yew wood, and used modern methods to steam the wood, dry it in the shade and air it for later use.

This most time-consuming, the longest time to make a good bow is the preparation of wood, which is why it takes three years for a bow to be successful.

The main production area of yew is China, which is an evergreen tree of the fir family, mainly growing in subtropical hilly places, and a small amount is also distributed in Vietnam, not only on the Mediterranean coast.

Originally, the production of bows and arrows also required horns and tendons, these materials that were easy to obtain in modern times were government-controlled materials in ancient times, and ordinary people could not buy them at all, and even if they bought, they were very easy to be put on a hat of rebellion, so Yang Wenli could only choose other materials.

Again, whether the material is good or not depends mainly on the energy storage density and elastic modulus. Horn is good, but there is an ordinary material that is comparable to horn, its energy storage density value is 1.39, and the famous bow is used in this material, it is tea stem bamboo.

Tea pole bamboo, also known as bitter bamboo, green hedge bamboo, and sand white bamboo, is mainly distributed in southern China, and is the most suitable bamboo for flute making and fishing rods.

After the tea stem bamboo is prepared, the part with the greatest toughness of the epidermis can be pasted on the abdomen of the bow handle to further enhance the elasticity of the bow body, and the back part of the bow should be pasted with animal tendons such as cow tendons and tied with silk threads, the purpose is to further enhance the elasticity of the bow arm, which is the classic of the compound bow.

Once the materials have been selected and prepared, the next step is to make the bow.

In fact, there is no difference between modern bows and arrows in range and power. This natural material is not weaker than modern synthetic chemical materials, such as carbon fiber, fiberglass, special steel and other materials.

The only difference is the norms, standards, etc,......
