The name of the spacecraft is "Longyuan". It was created by Ye Feng, and was taken from the Longyuan Sword, one of the ten famous swords in ancient China, also known as the Seven-Star Longyuan Sword. Therefore, it was also called "Seven Star Sword", and later changed to "Longquan Sword" because of taboos about Li Yuan, the emperor of the Tang Dynasty. It is also the sword in Li Xingyun's hand in the animation "The Bad Man in the Jianghu" - the Longquan Sword.
This sword is said to have been forged by two great swordsmen, Ou Yezi and Ganjiang. Ou Yezi and General Qian made the sword, cut open Cishan Mountain, released the mountain stream, and led it to the sword-making furnace to form the Big Dipper. After the sword is completed, looking down at the sword body is like climbing a mountain and looking down into an abyss. It is ethereal and deep, as if there is a giant dragon lying in the world, which is called "Dragon Abyss".
Although the craftsmanship of this sword is exquisite, its fame is still due to an ordinary fisherman whose real name is unknown: Yuzhangren. And the story of this fish-father-in-law is like this.
Wu Zixu was killed by a traitor and fled to the end of the world. He was chased by Chu soldiers and horses. One day he panicked and fled to the bank of the Yangtze River. He saw only the mighty river and rolling waves. There was heavy water in front of him and there were pursuers behind him. When he was extremely anxious, Wu Zixu found a small boat coming rapidly upstream. The fisherman on the boat kept calling him to get on the boat. After Wu Zixu got on the boat, the boat quickly disappeared into the reed marsh and disappeared. The pursuers on the shore left in anger. The fisherman carried Wu Zixu to the shore and gave him food and wine to have a feast. Wu Zixu thanked the fisherman for his kindness and asked him his name. The fisherman laughed and said that he traveled on the waves, so what was the use of his name? He could just call him his father-in-law. Wu Zixu thanked him and said goodbye. After walking a few steps, he turned around with concerns and took off the seven-star Longyuan sword that had been passed down from generation to generation from his waist. He wanted to give this sword worth thousands of gold to Yu's father-in-law as a thank you, and asked Yu to express his gratitude. Father-in-law must not reveal his whereabouts. The father-in-law took the Qixing Longyuan, looked up to the sky and sighed, and said to Wu Zixu: I rescued you just because you are loyal to the country and have no intention of repaying me. Now, you still suspect that I am greedy for profit and have little faith, so I have to use this sword to show my nobility. After saying that, he cut himself with his sword. Wu Zixu felt inexplicably regretful.
The story itself is nothing, but there is a stupid part, which is at the end. Anyone who is not a fool knows that the last Yu Zhangren could not have killed himself. He must have been killed by Wu Zixu. This is a typical story of a farmer and a snake. It is exactly the same as when Cao Cao killed Lu Boxe in the Romance of the Three Kingdoms, and Lu Boxe is where Cao Cao left the famous saying "I would rather teach me to betray the people of the world than teach the people of the world to betray me."
The two protagonists, Wu Zixu and Cao Cao, suffered from the same downfall, were rescued by good people, and had the same excessive suspicion. Therefore, learning history is still useful. It can make people less stupid. The reason why the story of Wu Zixu was passed down in the end can only explain two truths: First, history is always written by the victor, and she has always been just a little girl who was dressed up wantonly by the victor. 2. The lies of powerful people are always more convincing than the truth of ordinary mortals. What people believe is not the fact itself, what they believe is only the power.
Wu Zixu's character is nothing more than this, and Cao Cao understands Wu Zixu. Because the two of them are from the same place.
Okay, enough of the nonsense, let’s get back to the story.
After Ye Feng and others boarded the "Long Yuan" spacecraft, the gangway was put away. When the spacecraft began to take off, there was no loud noise as expected when the engine of the aircraft took off was started. Instead, it was silent. But just when everyone on the ground was wondering if there was something wrong with the spacecraft, the spacecraft flew away at a staggering speed. That speed is several times faster than the most advanced supersonic aircraft in the world.
Only a group of people were left on the ground. They had their own thoughts and soon dispersed.
The space inside "Longyuan" is larger than that of ordinary super villas. Inside, it feels like you are not on an aircraft, but like a house high in the sky. Everyone found a comfortable place to sit down and rest, and perhaps the busiest person among them was Ye Feng. Because who said that the current driver is only Ye Feng?
At this moment, Ye Feng was operating the "Long Yuan". Looking at the various large and small screens and buttons in front of him, Ye Feng also smiled slightly and sighed in his heart: I have to say, Yue Hong and the others are quite powerful. Although it is only very rudimentary to be able to create something like a curvature engine, this is the most critical first step in the history of human science and technology.
Just like when the car was born, it was busier than a tortoise. Coachmen all believed that this thing could not replace the carriage. But at that time, who could have imagined that the car would completely replace the carriage today. From the moment the wheels of the hulking steam car began to turn and move forward slowly, the entire history of the world began to turn.
At this time, Linglong came to Ye Feng and asked, "Dad, does this spaceship have a name?"
Ye Feng said: "The name is Long Yuan."
Linglong asked: "Long Yuan? Is it Long Yuan, one of the top ten famous swords in ancient times?"
Ye Feng said: "Yes."
At this time, Yun Xi came over and asked: "Master, how come the 'Long Yuan' doesn't make any sound from its power engine?"
Ye Feng said: "Because this spacecraft is driven by a curvature engine."
"Warp engine?" Linglong asked puzzledly, and at the same time, this was basically a question for everyone. Because when everyone saw that this spacecraft was not only faster than any other aircraft they knew, it should be said that such an aircraft would make a lot of noise, but at this moment, except for the sound of the spacecraft itself flying at high speed, there was no sound. Other voices.
Ye Feng smiled and said: "To explain the curvature engine, we must first explain what curvature is. First..."
Suddenly Yingying interrupted and said: "Feng, use words that a six-year-old child can understand."
"..." Ye Feng choked for a moment, and after a moment he smiled bitterly: "I know."
After Ye Feng thought for a moment, he continued: "Curvature is actually a numerical value that describes the degree of curvature of a curve. The greater the curvature, the greater the degree of curvature of the curve.
“To understand why something like curvature can be used as an engine, we must first understand the nature of objects existing in space.
"We know that two-dimensional space is a plane, but we can understand three-dimensional space as countless two-dimensional planes overlapping together. Then we will intercept one of the planes to illustrate."
As he spoke, a plane was projected inside the spacecraft,
Ye Feng continued: "And if there is an object in space, then the plane will look like this."
As the 3D virtual projection projected a ball on the two-dimensional plane, the ball fell to the two-dimensional plane like a cloth. What's interesting is that the two-dimensional plane also sunk like a cloth.
