For example, bow power can actually be calculated by arrow weight, because bow power and arrow weight must be matched reasonably. This principle is easy to experiment and the ancients were not stupid. They would definitely use the most matching bow and arrow to achieve the effect. Therefore, it can be

Use the weight of the arrow to calculate the bow power, and then combine it with historical records for comprehensive consideration.

Shi Wei's bow was a five-fight bow. Su You pulled it, and it was estimated that the force was more than thirty pounds.

The pass mark for soldiers of the Song Dynasty is seven battles, and Shi Xiaoniu is already very fierce.

Su You could only pull it halfway, but he was thick-skinned and was not as strong as his wife, so there was no pressure at all: "Weier, is there anything lighter?"

Shi Wei said "Ah": "No matter how gentle it is, it's just a toy."

Hey, look what you said, Weier, I gave you so many toys, why are you so embarrassed not to give me one?

Shi Wei felt that everything her little brother said made sense, so she took out a thin bow from under the box and said, "This one, I played it last year."

The bamboo poles used for arrows are also particular about this. The ancients would put the featherless arrows into the water and match the arrow feathers of the appropriate size depending on the part above the water.

You don’t need to be surprised, let alone surprised. This is not an invention of the Song Dynasty, but something left over from the Zhou Dynasty people a long time ago. It is recorded in "Kaogong Ji".

Su You didn't know how to shoot arrows, so he needed Shi Wei's step-by-step instruction. He moved the arrow twenty steps in front of him, and finally he was able to hit three out of ten.

Su You was so excited that he shouted, "Yes! Another shot!"

You tied up Zhang Zao and others with their hands covering their eyes, and you didn't even look at the densely packed targets fifty steps away from your little brothers and sisters. You still have the nerve to show off like this!

However, Su You was surprised when his hand was itchy for a while and he played with the whistle stick a few times, which surprised Su You: "Hey! Second brother, can you do this?"

Zhanzhao laughed and said: "After the female general came last time, the two veterans came to teach us a few tricks every day, saying that they can be used for a while in emergencies."

Shi Wei nodded: "It is indeed the same as the army, but it is the spear technique that binds Brother Envoy."

Su You scratched his head and said, "All the iron tools we made last time were bought by Atunmi. When we have time, we will make a few more. Short spears are not prohibited."

While talking, Shi Wei took the short spear from her home and took it off the shelf. Su You had a dark look on his face: "Okay, I take back what I just said, you guys are too good at taking advantage of loopholes."

This so-called short spear is a bit exaggerated. Although the total length is only more than one meter, which is not prohibited, the front part is not a spearhead at all. It is clearly a quickly polished short sword. There are two circles of small tines at the joint with the wooden handle.

According to Su You's knowledge, the official name of this thing should be "殳", which means "殳" with a short handle.

Shi Wei danced two routines, one with one hand and one with both hands, which could be cut, stabbed or struck. It was extremely fierce.

"Okay! Wei'er is so awesome!" Su You applauded wildly, then secretly changed the subject: "Well, let's go horse riding..."

Huang Chu was a arrogant horse, and Shi Wei comforted her again and again, so Su You was able to get closer.

Shi Wei shouted: "Brother Xiaoyou, you go up first."

Su You stepped on the horse and said, "Don't let go of the reins. If you let go, Brother Xiaoyou will cry his head out..."

Shi Wei smiled and said, "Take your feet out of the saddle. I will control the horse later."

Su You obediently let go of the stirrup, Shi Wei flew onto the horse, sat behind Su You, put her legs on the horse's belly and said, "Drive!"

Huang Chu first walked around the racecourse a few times, and then slowly walked onto the bluestone road.

Everything was fine up to this point, but after turning up a dirt slope from the bluestone road, Huang Chu seemed to have gone crazy and suddenly accelerated towards the mountain.

"I'm going!" Su You quickly grabbed Anqiao with both hands and lowered himself down. Shi Wei was behind him and held his waist with her arms, controlling the reins with her hands: "Charge!"

The wind whizzed by his ears, and the light brown horsehair swept across his face. Su You felt as if he had entered a storm. When everything calmed down, he realized that he had reached the top of the mountain.

Su You straightened up carefully: "It's really fast..." After saying that, he patted Huang Chu's neck again: "It's time for you to get a haircut!"

Shi Wei pointed forward from behind: "Brother Xiaoyou, look!"

Here you can see the panoramic view of the mountain below and the Kerongli opposite, separated by a verdant glass river. On both sides of the glass river are dense bamboo forests, and up are fields with water storage, and houses with mud walls and thatched roofs are scattered among them.

Each is surrounded by a building complex with white walls and blue tiles.

This side is Wubao, and the other side of the river is the ancestral hall.

A realistic version of "Dwelling in the Fuchun Mountains".

Su You couldn't help but sigh: "Wonderland...Weier, do you come here often?"

"Well, I often come here to sit."

The two dismounted, and Shi Wei led Su You to the foot of an old pine tree, where there was a stone.

The two of them sat down. Shi Wei took out a letter of rice krispie treats from the leather bag beside Huang Chu and gave half of it to Su You: "Brother Xiaoyou, here you go."

Su You smiled and said, "You can eat it. It's so beautiful here. I'll take a look."

Shi Wei said: "Brother Xiaoyou's food is the most delicious."

Su You said: "Oh, you exercise a lot every day, so you have to eat three meals. This rice krispie treats can be used as dry food on the road. Put it in a bowl and add boiling water, and it will be another snack: fried rice candy with boiling water."

At this point, Shi Wei felt a little depressed: "Brother Xiaoyou, I will leave Meishan after the Chinese New Year."

Su You comforted: "That was my arrangement. My brother originally wanted to ask you to go to Pengshan. I was worried, so I sent him a letter. He promised to let you follow him and go to the Chengdu Jade Bureau after the Chinese New Year.

Look, life in Chengdu is much better than in Pengzudong."

Shi Wei leaned on Su You: "Brother Xiaoyou, you are so kind."

Su You said: "When you get there, study hard. I will write to you from time to time. You should also read some basic physics and geometry, otherwise you and Shuanzhao will not be able to talk to each other."

Shi Wei asked: "Brother Xiaoyou, are there really gods in the world?"

This question stopped Su You: "Well... maybe there is, but we can't pin our lives on such illusions."

Speaking of this, Su You felt that he had to give Shi Wei a warning: "My brother is superb in Taoism and has recently been studying a subject called Chemistry. The litmus test paper this time was prepared for him, but that subject is very dangerous.

Some things will explode, some things are toxic and corrosive, you don’t have to get involved.”

"Medicine has been developed for thousands of years, and it is already vast enough. Just concentrating on medicine is enough for you to study it for a lifetime."

"There are also the theories we used in previous experiments, and those experiments on the digestive system, circulatory system, and nervous system. Although our answer is proven to be correct, we should not underestimate the theory of the old Taoist priests of Yuju Guan."

"Their medical skills come from experience, but they are still very profound. You can combine the two sets of theories based on experience and experiment to inspire each other and strive to create better medical skills."

"If you want to join my Su family in the future, you should know the rules of our Su family's learning: before you understand a subject thoroughly, you are not even qualified to say that it is not true. The most taboo of my Su family is to speak directly without thinking.

Taking other people's conclusions as your own is to take advantage of other people's wisdom, and wise people will not adopt it. You should always keep this in mind."

Shi Wei couldn't help but nodded.

Su You continued: "I think you can do in-depth research in two directions in the future. One is the cause and pathology. This predecessor has already followed the path, such as Chao Yuanfang's "Treatise on the Causes and Symptoms of Diseases"; the other is

The research and development of finished medicines can take many prescriptions in the medical field and develop them into effective pills, powders, and ointments, so that when there are many patients, there is no need to wait for medicines."

"There is a way to do this. In addition to many medical books from the past dynasties, Yu Ju Guan also contains many medical workers such as Meng Shu, Han Baosheng, etc., who took "Tang Materia Medica" and "Illustrated Classics" and corrected them together, and finally obtained the "Chong Chong" after deletion.

"Guang Ying Gong's Materia Medica". If you do these two things, it will be a great merit. These are the results of my discussion with my brother."

Shi Wei pulled Su You: "Although I still don't understand, I just listen to brother Xiaoyou."

Su You smiled and said: "I will come to see you when I have the opportunity. And if there is anything new, fun or delicious, I will ask someone to send it to you. Don't worry. It may not be long."

, I also have to go to Chengdu to study."

Shi Wei finally smiled: "Chengdu Mansion has more books than Uncle Cheng's bookstore?"

A look of yearning rose on Su You's face: "In the Chengdu Academy, there are the "Book of Filial Piety", "The Analects of Confucius", "Erya", "Book of Changes" and "Shangshu" engraved by Wu Zhaoyi, the former prime minister of Meng and Shu.

, "Zhou Rites", "Mao Shi", "Ritual", "Book of Rites", "Zuo Zhuan" among the ten classics, the book elixirs include Zhang Dezhao, Yang Jun, Zhang Shaowen, Sun Fengji, Peng Ji, Zhou Dezhen. All of them were masters at one time.

There are thousands of Su Shi Fans, all based on the old version of Taihe, and it took eight years to complete."

"In the first year of Huangyou's reign, Tian Kuang, the prefect of Chengdu, engraved "Gongyang" and "Guliang". The key point is that all these scriptures not only have copies, they also have notes. This is a great treasure. If you don't get ten sets of rubbings and put them at home,
