was actually assigned to the pioneer battalion, with such poor martial arts, wouldn't it be a dead end? Yan Yu suddenly had a flash of inspiration and spoke:

"Qi Yu Yan Shuai, although we didn't catch Ling Tong this time, it wasn't for nothing. Pen, fun, pavilion www. biquge。 info”

"Oh...... Tell me about it? ”

"We know why the same breed of Hu dwarf horses, why our horses are significantly inferior in endurance and speed, why our cavalry can't catch up with them, not because of their inferior skills, but because of this thing."

Yan Yu said as he took out a horseshoe from his arms and handed it to Yan Baihu, who looked at it over and over again and asked:

"What is this, and where does it come from?"

"This thing was found by his subordinates on the hooves of an enemy horse that had stumbled and fallen off a cliff during the pursuit today, and it was nailed to all four palms. I consulted the blacksmith and the horse trainer, and they all praised it as a genius idea that slowed down the wear and tear of the horse's hooves, not only protecting the horses' hooves, but also making the horses' hooves grip the ground more firmly and greatly improving performance. ”

Yan Baihu bowed slightly: "Yes, it's not useless after all, huh...... It is also considered meritorious, and the rod punishment is written down first, and the next time it is committed, several crimes will be punished together. You and Ren Chuan will be temporarily incorporated into my escort team! ”

The two were overjoyed and said, "Thank you Yan Shuai!" ”

"Yan Shuai, there is one more thing, you should also take a look at ......"

Yan Yu clapped his hands, and the soldiers standing outside the tent presented a strange bow, this is a recurve bow, the bow arm is made of the best wood in the bow, and the bow handle is even more polished by the palm of the finger. The peculiarity is that a single wheel (fallen wheel) is in the upper part of the bow, and another elliptical pulley that provides energy is in the lower part of the bow.

Yan Baihu was surprised: "Why is this bow so peculiar? ”

"Yan Shuai, don't look at this bow strangely, this is a four-stone strong bow! And the enemy army is 300 people, and each of them can draw this bow. ”

Yan Baihu was shocked and blurted out: "The thief army is so strong? ”

"No, no, no, my subordinates also thought the same as Yan Shuai at the beginning. As we all know, this ordinary man in the prime of life can shoot a strong bow with one stone; With a little training, some people can open two stones; Those who can open three stones, there is no one in ten thousand; If you can open four stones, you must be born with divine power and superb martial arts, and these two high-ranking generals are just that, how can there be a reason that everyone is like this for ordinary soldiers? ”

"yes, and then what?"

"Yan Shuai, try this bow for yourself, and you will understand ......"

Yan Baihu walked out of the military tent, saw a group of flying in the sky, opened his bow and drew arrows, only to hear a wail, a planted from the sky......

"Good archery!"

"Awesome!"

……

Everyone slapped their farts wildly, and Yan Baihu looked at the bow and arrow in his hand strangely, "Look at this strength, there is no doubt that the four-stone strong bow is there, but why is it so easy?" ”

"That's right, according to the research of his subordinates, these two pulleys play a magical role, obviously it is a four-stone bow, but it only needs a pull between two and three stones to open the bow. Although the subordinate does not know the principle, it is really a genius idea, and it is a miracle workmanship. ”

A trace of gloom hung on Yan Baihu's face, "Just two wheels, how can they have such a miraculous effect?" ”

In fact, any modern person who sees this bow must recognize it at a glance, isn't this a modern compound bow? Even if you are not a lover of bows and arrows, you can see this kind of bow in various competitions.

Wheel bow, the common name of modern compound bow, is named because most modern compound bows use pulleys to achieve the effect of labor-saving. It can be roughly divided into four different pulley systems: single wheel pulley, hybrid wheel, double wheel soul wheel, and binary pulley.

This bow is the simplest single-wheel skate. Compared to a double wheel bow, a single-wheel system is generally quieter and easier to maintain. Since the round falling wheel and the elliptical power wheel in the single-wheel system cannot rotate synchronously, it is theoretically difficult for the single-wheel system to provide a straight arrow path. Moreover, this pulley system is not easy to "balance" (refers to the balance between fast speed and good feel), this kind of bow is either very fast but difficult to master, or it is very smooth but relatively "soft", and it takes a lot of thought to adjust it to a satisfactory effect.

However, these drawbacks are almost negligible for Zhang Fan, after all, this is not a competition, and there is no need to shoot accurately on the battlefield.

As the saying goes, science and technology are the primary productive forces. The ancients did not know much about physics, although pulleys have been used, but most of them have been superficial, and the use of pulleys for bows and arrows is almost imaginative, and for them it belongs to the category of long postures.

Yan Baihu frowned, "If the enemy army has this bow in his hand and is condescending, wouldn't our army be slaughtered by others?" ”

"This ......," Yan Yu said with relief after a moment of silence:

"Yan Shuai, please rest assured, this bow is not easy to make, maintenance is even more laborious, and the cost is more than three times that of ordinary bows and arrows, and it is unlikely that the thief army will have ......one hand."

Yan Baihu really overestimated Zhang Fan, after all, the ancient production industry is not comparable to the modern one, and with Zhang Fan's financial resources and manpower, he has only made five hundred pairs of these wheels in the past three months. Non-elite soldiers are not eligible to use it, and this is the first time it has been used in actual combat, and the effect is amazing.

Although Yan Baihu is short-tempered, he is not stupid, and he can't help but regret it a little at this time, this first has a horseshoe, and then this round of bows, there must be capable people in this Huanglong Village! Obviously, I underestimated this sail, so it was too hasty to lead the army to attack so rashly?

If these two things had been discovered earlier, they would have been copied, but the war was imminent, and there was no time.

This army has not yet arrived in Huanglongzhai! Due to Ling Tong's incessant ambush and harassment all the way, the three-day journey was forced to walk for five days before it arrived, and eight or nine hundred people were lost, and nearly two thousand were wounded.

Alas! Yan Baihu sighed, but how could there be a turning back arrow when he opened the bow? The arrow is on the string, and it has to be sent, and at this time, it can only take one step at a time.

Fortunately, he can rush to Shanyin County tonight, as long as he is careful, Ling Tong will not have a chance to harass him no matter how much he wants to harass!

Yan Baihu understands that now is not the time to be discouraged, as the main general, he is depressed, and the army's morale will inevitably be turbulent, then it will be completely finished! Reluctantly brace himself and commanded:

"Go down and prepare, and continue the march in a quarter of an hour!"

The generals listened to the order to gather their subordinates and pack their luggage......

At this moment, a spy flew over and returned the latest information to Yan Baihu, Yan Baihu was overjoyed after hearing this, grabbed the spies' shoulders and asked:

"Can you hear me clearly?"

"Qi Yu is handsome, it's true."

"Hahahaha......" Yan Baihu looked up to the sky and laughed, "God bless our army!" Zhang Fan? Ling Tong? See how you die? ”

"Someone's coming!"

"The subordinates are here."

"Prepare for the banquet, Ben Shuai will personally greet the nobles......"

"Order!" Yan Jie saluted and retired......
