There were no ripples in the boudoir. Princess Jiaxing thought about it and went downstairs, but did not ask the little girl on duty. She told the palace people not to follow her, but only brought a personal palace maid through a moon gate open in the east flower wall...

As soon as I came out, there was a rippling plain lake in front of me, covering an area of ​​about a dozen acres. Some water birds raised in the lake swam leisurely on the water surface, and a building was built on the island in the middle of the lake.

From a distance, there are willows in front of the island. There are winding veranda on both sides to the south, blocked by flower walls. Opposite the flat lake is an octagonal pavilion, half of which is faintly exposed outside the willows, dozens of steps west of the pavilion, and a fishing platform is protruding under the corridor, with red walls and green windows, and carved railings and stones.

The island in the center of the lake is located in the Baishi Bridge with a white stone railing in the northeast, which goes directly to the other side. Jiaxing knew that no one lived here before. Since the Ripples came, all the nearby buildings were taken for herself by her unceremoniously.

With his head tilted, Jiaxing said to himself: "Would we live on the island?"

The palace maid shook her head and said, "It's too dangerous to have water on all sides, so I will definitely not agree."

"This one is not good, that one is not good." Jiaxing was a little angry, "Am I still a princess? Anyone can point fingers at me."

"Hehe!" the palace maid smiled, "Who told Your Highness to have not yet left the house? Besides, even Your Majesty is controlled by a group of people all day long. There are eunuchs in the palace and ministers outside the palace. They have gone wherever they said, done, and everything they have to be recorded in every detail. Otherwise, why do they all love to come to the Xu Mansion? Only when you come here is truly unrestrained. Look, there is not even a figure around us."

Jiaxing also smiled and said, "No wonder my father lost his temper all the time this year. It's because his uncle is not at home. Have you noticed? No matter whether he is eunuchs or ministers, everyone is afraid of his uncle. On the contrary, no one is afraid of his father. Last night, he lamented that he was not happy at all as the emperor."

The palace maid said, "The Queen said that he would be strong without desire, and that's what Lord Xu is like. He is the most powerful minister but he is willing to not be an official and does not take power. He dares to blame him for his mistakes when encountering things. If there are eunuchs who do evil, they dare to order people to beat him to death. Didn't Your Majesty say that he is the Eight Virtue King of the Ming Dynasty?"

Jiaxing suddenly said, "Uncle also has his uncle's difficulties, otherwise why didn't he return to Beijing for nearly two years? Fortunately, the emperor wrote to me and said that he liked his uncle more and more."

"What does Your Highness mean?" The palace maid didn't understand.

"It's nothing, let's go." Jiaxing said and walked forward.

The corridors in this area are all circular and can be used in a circular shape. I specially asked the emperor to design them into a nine-curve corridor dedicated to the royal family, with a total of nine twists and turns. There is also a corridor outside the corridor, connecting the scattered buildings in various places into a whole. It is no wonder that Ripples are taking over. It was originally designed to design a group courtyard specially for the next generation of the young ladies of the Xu family.

At this time, the water surface in the lake was calm, and the weather in October began to desolate.

The Princess Jiaxing did not go to the island, but passed through several rockery caves, walked over from the banana and bamboo forest, and entered one door. There were three large-scale cavities, four wing rooms on both sides, and two Western Begonia Begonia plants planted in the heart of the courtyard.

As Lianyi moved in, Xu Ye and Xiao Yezi also moved in. This is Xu Ye's residence, and Xiao Yezi lives in the Rainbow Tower behind.

Through the glass window, we could see that the house was full of servants. There were also little girls walking around in the corridor. Jiaxing knew that he had found the right place, so he gestured to the servants, signaling them not to speak out and went straight into the house.

The room was extremely warm. Princess Jiaxing took off her cloak and several people were chatting in a circle.

He heard Ma Yu, who turned his back to him, saying, "Gunpowder was invented by our country and gradually spread to the countries of the Western Regions, Tianzhu, Dashi and Persian countries. During the reign of Song Zhezong, China was the first to invent artillery weapons, but the craftsmanship was very rough. In the history books about foreign countries, the Persian king Alexander attacked Tianzhu. He heard that there were firearms in his military camp, so he secretly sent spies to inquire, but he didn't find anything. It can be seen that the firearms in India at that time were just following the crowd.

In recent years, people sent to India said that there were not even books there, and there were many small countries, and there were strong enemies eyeing covetously in the north, while the countries in the south were drunk and dreaming. There were countless dialects in various places, without unified weights and measures, without imperial examinations, and without books and writings, it was difficult to find Sanskrit books, so I think India did not invent a firearm."

Jiaxing was confused when he heard this, and saw Xu Ye sitting next to him, saying: "Our group has specifically verified that in terms of cultural heritage, Europe and Persia are much stronger than India. My father said that the ancient Indian civilization, which is no less than Chinese civilization, has long disappeared. In terms of cultural heritage, Venice can be called the highest in Europe, unlike the Persian countries and European countries who have lost many precious books due to years of war. Unfortunately, the power of the Roman Catholic Church is too great and has burned the library several times.

During the Five Dynasties, the Roman Empire used Greek science to build a machine rocket, sealing the turbulent oil in a box, which was placed in a copper tool and sent out with a catapult. Even if it was a firearm, how could it be compared with our China?"

"That's nature." Ma Yu looked proud.

He sat opposite him with Riyi waves, waved to Jiaxing, and asked, "You male students talked endlessly when they talked about muskets and cannons. Is it really that powerful?"

Ma Yu was surprised to find someone coming, so he quickly got up to see the salute. Jiaxing returned the salute generously, walked to Lianyi's side and sat down, curiously looking at the young man in front of him. As soon as he was older, Ma Yu was four or five years older, and he was already an adult.

When lifting the firearm, Xu Ye knew it carefully and said: "In the 29th year of Hongwu, Fengyang General Manager took the lead in building twenty new cannons and began to study the art of cannons. In less than three years, the skilled craftsman created light cannons, using thin copper as a bore, using leather on the outside, and using iron chains on the outside, firing two-pound stone bullets with built-in gunpowder. In the same year, Fujian also cast new iron cannons, but they were too bulky and needed twenty horses to pull them to move.

A few years later, a gun factory was set up in Peking and a very flexible short cannon was quickly developed. This was the beginning of the horse-drawn cannon. At that time, the earliest flowering cannon was used, which was different from now. Haha! My father proposed the lucky line cannon."

Jiaxing interrupted and asked, "What is the blessing line?"

Ma Yu explained: "The path of the bullets in the cannon has long round and thick thread troughs. Shibo called it the blessing line, which greatly improved the range and accuracy. Therefore, the cannons had already set up a straight line at that time, but they had to fill gunpowder at the muzzle. Speaking of which, Shibo was a genius in firearms, and successively proposed methods of post-boring and loading drugs. Now most cannons are like this. They are called General Xu's cannons in the army."

Xu Ye said proudly: "You don't know yet? Last year, the Beijing Artillery Factory developed the method of refining iron and solid copper, and made a cannon with a maximum range of more than 3,600 feet, more than 1,000 meters, and weighing 800 kilograms. This kind of steel is called iron armor. My father is still not satisfied with this and urged the 300 skilled craftsmen to develop a continuous bead cannon day and night. It is said that it requires 300 shells to be fired in one minute, and there is also a giant cannon with a range of at least 40 miles. If it can be successfully developed, the iron cavalry on the grassland will no longer be the enemy of my Ming Dynasty."

Ma Yu hurriedly asked, "Shibo has a new musket that does not need to be filled with gunpowder. What is the principle?"

Xu Ye scratched his head and said, "I don't know much. I only know that it is divided into two types of explosives, one is the temporal drug, and the other is the striking drug. There seems to be a small steel needle in the bullet, or it is the gun. When the bullet moves, the steel needle will rush into the barrel, causing the two gunpowder to strike each other and explode. The projectile will be fired out."

Jiaxing said in admiration: "You two know a lot. How do you know where the firecrackers fall?"

"This is simple." Xu Ye knew much more about this than Ma Yu, who specialized in the Four Books and Five Classics. He said without thinking: "It is a parabola algorithm that has a total of fifteen degrees of difference between high and low. From top to bottom, gradually down, to a certain limit of parabola resistance, there are several ways, and from top to bottom, from this limit, there are also several ways.

If it is fifteen degrees, it is within the range of the short-range artillery, because the human eye is less than nine thousand feet long, and the surveyors use telescopes to measure it. I don’t know much about how to measure it.”

Ma Yu asked: "Shenji Camp said that weapons are the most exquisite, how was the artillery battalion set up?"

Xu Ye said: "The artillery battalion is equipped with various types of artillery and ammunition. The artillery of the Shenji battalion is divided into five battalions, eighteen teams, and 18 teams, with 18,630 soldiers. In addition, there are twenty flight transporters accompanying the team, fifteen soldiers slowly transporting them, three heavy transporters attacking the city fortress gates, and 20,000 horses of various types. However, I know more about Liaodong. There are more than 7,400 officers, more than 2,500 soldiers, more than 120,000 soldiers, more than 38,800 war horses, more than 38,800 guns of various types, and there are also reserve soldiers, more than 58,000 first-class military households, about 40,000 second-class 40,000, with a smaller number of people. There are 140,000 third-class 13 admirals, and more than 65,000 naval officers and soldiers."

Not to mention that Jiaxing was confused when he heard it, Lianyi was as confused as Xiaoyezi, and Ma Yu didn't know how powerful it was. In fact, even Xu Ye himself only knew the surface. Most of them heard it from his fourth uncle Xu Song and his uncle Mu Yi, and they were not sure about it. This was the highest military secret of the Ming Dynasty.

It can be said that in terms of the number of people, the total number of soldiers in Liaodong has been decreasing year by year, and there is nothing to see. In fact, the quality of soldiers is the highest in the country. The number of officers and soldiers has reached the proportion of modern army. You should know that the total strength of the modern British Empire is almost the same as that of Liaodong today. The 60,000 naval forces have long exceeded Liaodong's own needs and are facing the entire world.

The girl was not interested in this, but Ma Yu was very excited and asked questions continuously, but unfortunately Xu Ye was not very satisfied.

Taking into account the previous question, Jiaxing said: "I have to hit two and a half miles away, how can I calculate it?"

"I can't calculate this." Xu Ye smiled and said, "If you use the geometric formula, set a pole and make a centering point, and say how far the cannon's farthest forty-five degrees can it reach, how much higher the centering point, how many feet higher, and how much higher the centering point at this time, I will forget it."

Jiaxing didn't believe he could do it, and whispered with Lianyi. Xiao Yezi went to find the latest "artillery foundation" and ordered people to take a piece of paper and wrote: A red light hung on the pole of the city tower. The light was to be hit with the farthest artillery of forty-five degrees. Because he first used a rod to measure the light at the position of the cannon and then retreated 78 meters; he also had to measure the light eleven minutes, and used this ratio to find out how to hit it?

Ma Yu was dizzy when he saw that he shook his head and said, "This is a big question. He took it to the Imperial College and kept it. Few people could answer it from the 1,000 people, or maybe none of them."

"That's your Imperial College." Xiao Yezi said softly, "Although it's difficult, Ye'er, he studied at the Liaodong Army Academy for half a year last year."

Ma Yu still shook his head and said, "I don't believe it." This topic is like a heavenly book for him, and he can't believe that Xu Ye, who is young, can do it even if he is beaten to death.

Unexpectedly, Xu Ye repeatedly wrote some formulas on the paper, and finally wrote: The red light is 859 meters away from the cannon position, three meters above the flat ground, and then the parabola is rated as parabola, and the gun axis can be hit by 11 degrees and 40.50 degrees and 40.50 degrees and 40.50 degrees and 40.50 degrees and 40.50 points.

Princess Jiaxing compared the answers in the book and exclaimed: "I've answered correctly."

Ma Yu was stunned and said, "I really want to provoke your current knowledge."

Xu Ye said, "These are all formulas calculated one by one by the teacher and senior brothers based on the writings of the sages. We are learning and applying them through ready-made things, otherwise how could it be so easy."

Jiaxing also admired him very much and thought that everyone is just as old as they are, why are they so far apart from them?

This yearned for her plan to live in the Xu family even more, and turned to ask Lianyi: "I want to live here too. Do you think I'll choose where?"

Lianyi said excitedly: "This place attracts the water from Yanque Lake, flows north into the garden, and reaches my Lianyi Little House, and crosses the Baishi Bridge to the west. How about the island in the lake? Otherwise, on the Rainbow Tower of Sister Ye, the flowing water passes through the slanting bridge and accumulates a pool to the southwest. It is the Yue Lake of Xu's family. There are Gengyun Xiaozhu and Linglong Pavilion nearby. However, I like Caiyun Villa, which has a spacious yard and a large number of rooms and rooms, which are enough to accommodate the people around you. Do you know the couple there?"

"I don't know, tell me quickly." Jiaxing couldn't wait to urge him.

Lianyi smiled and said, "When there is water flowing, you can wash your eyes, and you can borrow the Sutra of Contemplation everywhere without dust."
