500 years have passed since the discovery of the Level 2 Light Energy Civilization spaceship. During this period, Yan Xia hibernated several times, and the time he opened his eyes was no more than 5 years. Most of the awakenings were due to the problems of the Hundred Eyes. It is impossible to completely colonize a civilization in a short period of time. It must go through an extremely long process. For the Hundred Eyes, Ella's calculation result is exactly 500 years. This time, Yan Xia awakened not for the Hundred Eyes. But their civilization has entered a new level again. The controlled nuclear fusion device has been iterated. After mastering the antimatter cannon, the development of positive and antimatter annihilation energy has been put on the agenda. This is a longer process than controlled nuclear fusion, because the energy generated by positive and antimatter annihilation is higher, and it must be coordinated with the upgrade of other industrial chains to truly become a device that can be mass-produced. Now Ella has completed the technology. It uses the special metal on the surface of the spacecraft.
After Ella's research, the metal is an alloy combined at the quark level. Its essence is not even all-metal, but a combination of gold and stone. Its half-life is billion years, its density is ³, its Mohs hardness is 15, its melting point is 87,000 degrees Celsius, and the most terrifying thing is its strength, which is 14127Mpa, which means that every square centimeter can withstand 144 deniers of force. The only disadvantage is that the density is too high, which will affect the speed of the spacecraft. However, the things on it are actually just basic operations. There are only four words that shocked Yan Xia. No charge. The Level 2 civilization has obviously been paying attention to the influence of magnetism on objects. After removing the charge, the magnetism cannot generate Lorentz force on the object. This indicates that the war of Level 2 civilization involves the four fundamental forces. Using fundamental forces as weapons, it also defends against fundamental forces. It took Ella 420 years to master the manufacture of this metal and apply it to various fields. The Hope has also been reborn. Yan Xia put on the space suit and walked out of the Hope. From the outside, the originally black Hope turned into bright silver, and the entire spacecraft seemed to be spliced with mirrors. The rear half of the entire Hope has been dismantled and replaced due to the transformation. A robot passing by Yan Xia suddenly turned around and said to Yan Xia: "Yan Xia, I will send a car to pick you up to the factory in a while, where we are waiting for you to observe the great progress in the past 500 years." The voice was Ella's. Yan Xia nodded, and then looked at the place where the spacecraft was. It should have been a ruin buried in sand. After 500 years of development, it has become a giant city with skyscrapers everywhere, bright lights and wine, which made him feel that it was no different from the earth at first glance. The difference is that this city is more cyber.
Not only are there lanes on the ground, but some lanes also shuttle between buildings 2,000 meters high, and even tens of thousands of meters high in the air, forming a complex road network. These vehicles have no wheels, but use magnetic levitation, and can be up to 300 meters above the ground. At a glance, there is light everywhere. Huge billboards, holographic projections, vehicle lights, lights from thousands of households, everything is connected together, illuminating the entire city like daylight. It's just that the people living in this city are not humans, but the Hundred Eyes and robots. "No, I'll just take the maglev train there." "I want to see this city." Yan Xia wanted to feel the prosperity, maybe because it was too long, or maybe he was old, if he didn't watch the movies generated by Ella, etc., he even forgot the scenes of the earth. Walking into the city, there are many semicircular covers in the city, and various earth plants are planted in those covers. The roadside is full of Hundred Eyes. Wherever Yan Xia goes, all the Hundred Eyes will disperse. Through the real-time translation of the system made by Ella, Yan Xia can know the emotions and language of these Hundred Eyes. Fear. Curiosity. Looking up. Like humans, the Hundred Eyes are complex as highly intelligent creatures. These slime creatures weighing 3 meters sometimes express emotions even more richly than humans, perhaps this also comes from the eyes. The eyes of the Hundred Eyes can see more colors than humans, and more colors allow them to have more artistic expressions. Art is one of the foundations for the birth of complex emotions. The only thing missing in the whole city is noise. The whole city is a little scary quiet, after all, this planet has no air. Walking through the most prosperous commercial street in the city, there is a square with a magma pool in the center. Reaching the top of a tall building through a 1,200-meter-high elevator, there is a huge platform. There is only one layer of metal plate track connecting one end of the sky to the other. A 6-meter-high and 8-meter-wide bullet train came silently, and the huge light bulb on the head flashed, indicating the arrival of the train. Slowly reduced from 1,000 kilometers per hour to 0 and stopped. The huge door opened and Yan Xia walked in. There were no seats here, and the empty carriage was filled with the Hundred Eyes. Soon the train started, leaving the city and entering a barren area. Here you can only see the scenery formed by giant semicircular glass covers and volcanoes. Each semicircle is at least 10 square kilometers, and there are earth plants inside. There are more native plants around the volcano. They thrive and are mostly brightly colored, some of which even emit a faint fluorescence.
Half an hour later, Yan Xia arrived at another city. This city is more like an industrial zone, with factories everywhere, no entertainment, no housing, only countless mechanical parts. A robot came over as soon as Yan Xia got off the train. "Come with me, Yan Xia." He and the robot took a special elevator placed on a stone platform. This elevator did not go up, but down. After about 100 meters of soil, Yan Xia's eyes suddenly opened up. This is a place like a large stadium in a ring, but it is much larger, with a diameter of 15 kilometers. The elevator is located in the center of this ring. Yan Xia looked down and saw a primitive rainforest. Only real botanists who come to these rainforests will find that these trees do not belong to any known species on Earth, because these trees are all Earth-like plants created by Ella through gene editing. After descending another 4,700 meters, we finally reached the ground of the underground space. This is a white hall with doors of various colors in all directions of the hall, and the destinations are marked with Chinese characters. Walking into the door, there is a long tubular corridor. Instead of walking, you are taken by a parallel escalator. The corridor is full of screens showing various animals on Earth. After reaching the end, Yan Xia walked through a square door that was 200 meters long and only 40 meters high. After walking to the end for 10 minutes, he suddenly looked up and saw the starry sky. This is in a natural pit with a diameter of one kilometer. At the bottom is a metal platform that fills the pit. Almost all the rock walls in the pit are blocked, and various huge mechanical arms of tens of meters are distributed everywhere. Yan Xia was arranged to enter a huge living room that protruded and suspended on the rock wall. The living room was already full of more than a dozen hundred-eyed people. They have a very high status in the Hundred Eyes Clan, with rulers, top scientists, and military commanders... When Yan Xia sat in the front. A part of the platform began to descend, and a huge deep hole appeared. A huge wall rose around it, blocking all the mechanical arms, including their hall. Ella appeared. The glass in front of them turned into a display screen. "Yan Xia, please watch my demonstration."
