Several people believed in the horse and waited until they arrived in Bianjing City. The princesses gathered at Princess Chen's mansion.

The three daughters of Song Yingzong were originally titled Dening, Baoan, and Shoukang, and their relatives also used to call the three princesses this way.

After adulthood, Princess Dening became the princess of the Xu Kingdom; Princess Baoan became the princess of the Shu Kingdom, the princess of the Shu Kingdom; Princess Shoukang became the princess of the Qi Kingdom, the princess of the Wei Kingdom.

After Zhao Xu ascended the throne, the titles of the three people should actually be Princess Chen, Princess Shu, and Princess Ji.

However, many people still retain the names they had when they were growing up, calling them Dening, Baoan, Shoukang, or Xu, Shu, or Wei.

Anyway, Zhao Xu’s daughter is still young, so she can’t let everyone scream.

Princess Xu is the eldest sister, and she is usually very cold and solemn to her younger sisters. Princess Shu is a bit better, and Princess Wei doesn't come to the house if she can.

But today is different. Thanks to Shi Wei, several princesses have been seriously ill for more than a month, but they have managed to survive.

Especially the princess of Shu. In real history, she died during the mourning period of the Empress Dowager.

Although he is not well yet, under Shi Wei's care, at least he is not seriously ill.

Therefore, after Princess Xu received the post from Zhang Dunli and Su You yesterday, she brought several princesses and Shi Wei to her house and ordered Prince Consort Wang Shiyue to prepare a treat.

Master Wang greeted everyone at the gate early in the morning. When he saw Su You and the others coming, he laughed loudly and said, "Today is a rare occasion. Shaobao, I have been looking up to you for a long time."

Su You stepped forward and said the courtesy: "I don't dare, my brother is both civilized and military, and Su You has always admired me. Today I came to ask Zi Yu for advice."

Several of the princes-in-law of Emperor Yingzong of the Song Dynasty were all talented in literature, proficient in the six arts, and knew everything about music, chess, calligraphy and painting.

When a princess falls, she is destined to give up her personal career. If she has no sustenance, she may become like Wang Shen, and her mentality will gradually become narrow and abnormal.

Wang Shiyue was a good person, mainly because the royal family gave the Wang family enough respect. In addition, his literary talent was not particularly outstanding and he had no pride. Princess Xu was not arrogant, so the couple had a good relationship.

Princess Wei was a bit cute and naive, but she was also a little fan of Zhang Dunli. It was precisely because of her shortcomings that Zhang Dunli liked her, and the couple got along well.

On the contrary, the princess of Shu was too perfect, but she left regrets because of her perfection.

…

Although it was Su You who came to ask Su Che for archery skills in name, what everyone wanted to see more was Su Shi.

In order to achieve this goal, Princess Xu specially divided the main hall into two sides with flower panels. The men drank tea and talked on one side, while the women ate and peeped on the other side.

Zhang Dunli asked his subordinates to fetch the treasured bows from his family: "Speaking of these bows, it is thanks to Shaobao's blessing. They are the Xingzhou treasured bows that Shaobao captured from the Xia people during the battle in Weizhou."

The weapons of Xixia were actually more sophisticated than those of the Song Dynasty.

This is caused by institutional problems. The tribal system was first implemented in Xixia. After the founding of the country, the tribes were actually military groups of various sizes.

Weapons are their private property and are often passed down from generation to generation. Although the output is much smaller than that of the Song Dynasty, the level of sophistication is higher.

This situation is somewhat similar to the comparison between the weapons of the Japanese pirates and the weapons of the official army in the Ming Dynasty.

Xingzhou is Xingqing Prefecture. The craftsmen there are not lacking in strength, and the bows they make are the best in the world.

Bows in the Song Dynasty generally cost two guan, while the price of Xingzhou bows was more than ten times that of Song bows.

However, now the production capacity of the Song Dynasty has increased, science and technology are advancing rapidly, and troops are generally equipped with crane-shank crossbows.

Bows have begun to be gradually phased out and used by volunteers and Tibetan troops.

As for traditional bows, there is now a trend of development in the direction of cultural toys and sporting goods.

Su You tried to open it, but found that the bow cost at least three stones, and his arm strength could not handle it at all: "Did the prince-in-law frighten the Liao people with this bow back then?"

Master Wang asked his servants to bring over a box of arrows: "The bow is second. If it breaks within seventy steps, the arrows invented by Shaobao are the key."

After speaking, he took out two feather arrows and said: "These are the best large-feather arrows ever made. The first thing you pursue in archery is the hit, and then the strength and speed."

"The carved feathers and large feathers are the most stable among all arrows. Of course, the price is also very high."

"In the past two years, another type of large-feathered arrow has become popular in Bianjing. This, speaking of it, is your discovery."

Su You smiled and said: "Actually, it's similar to Diao Ling, right? It's just black and white, so the visual effect is better."

Wang Shiyue also smiled and said: "Indeed, this is the feather of the South China Sea toucan. The feathers are large and distinct in black and white. The feathered arrows made are more gorgeous and the target is more eye-catching. Now there is such a feathered arrow in Beijing.

, the cost is between one and a half to two guans.”

After speaking, he picked up the third type of arrow: "Actually, this is the one that showed off its power before the Liao people this time."

Su You took a look and said: "The price of this arrow has dropped when the prince consort used it..."

Wang Shiyue waved his hand: "This is the three-tailed small feather arrow invented by you, Shaobao. The so-called great simplicity has an additional tail feather, and its stability is not weaker than the large eagle feather; at the same time, this..."

I made some gestures with my hands and couldn't find the words to describe it for a while.

Su You said: "Air resistance."

"Yes." Wang Shiyue said: "The air resistance has been reduced a lot, and the arrow speed in the air has accelerated a lot, so when it reaches the target, this..."

"kinetic energy."

"Yes, the kinetic energy is much greater than that of the Eagle Feather Arrow. Targets that could not be broken before will be no problem with this one."

Su You smiled and said: "The prince-in-law is not picky. After mass production of this thing, the price is actually very cheap."

"That's what I want!" Master Wang said with a thief smile: "The quantity is also large! The small feather arrows I use now are all picked out every month in the arrow shop. The price is higher than ordinary feather arrows, but every time

The weight, center of gravity, size, and accuracy requirements of an arrow are much higher than ordinary standards."

"With hundreds of arrows like this, we can develop a precise feel. Hahaha, I guess the gap between the Liaoning workshop and my current workshop in the Song Dynasty is too big, so that's why they were shocked."

Su You took the long arrow from Wang Shiyue's hand and said, "This is the power of standardization."

Seeing that some people were still confused, Su You explained: "The so-called standardization is actually to achieve the ultimate in the four skills of unification, simplification, coordination and optimization."

"The so-called unification is to determine a consistent specification based on the process, performance or other characteristics of things in order to ensure efficiency and performance, and what is pursued is identity."

"For example, today's workshops in the Song Dynasty all have standard serial processing molds and measurement standards for arrowheads, arrow shafts, tail feathers, and chords. The same model of fletching arrows produced can be interchanged with each other. This is the same

The embodiment of sexuality.”

"The so-called simplification means to screen, refine, and decompose the structure, type, and specifications of standardized things at the beginning of the design in order to meet the needs most cost-effectively. Eliminate all redundant, inefficient, and replaceable links and structures.

, refine the links that can meet the needs and have high efficiency to replace them, keep the overall streamlined and reasonable, and pursue the simplicity of things."

"For example, in the production of arrowheads, there used to be a variety of molds, but now they are all unified into a triangular pyramid head, which is stamped and formed in a unified way. The arrow tail uses a unified Serul tail feather and a rubber stringer, which greatly simplifies the process."

"The so-called coordination means to coordinate the relationship between all local related factors in an effective way, making it possible to establish, balance and maintain consistency."

"Let's take the production of fletching arrows as an example. Today's biggest process bottlenecks are the drawing, steaming and painting of arrow shafts. Therefore, when we set up workshops and production lines, we have to allocate fewer workers to produce arrowheads and tail feathers.

Some, and the number of workers who produce arrow shafts must be larger to avoid a large number of arrow fletchings without arrow shaft assembly.”

"The so-called optimal means to achieve the most ideal effect by adjusting the above three points according to specific goals and under certain restrictions in order to meet the needs of standardization."

"The feather arrows designed and produced under this idea give up the gorgeousness, complexity, and refinement; they only pursue performance, lethality, and output. This means targeting specific goals and certain restrictions."
