"The data of the galaxy ahead has been entered." "Name: sc-19, a white dwarf, no transits have been observed, and there are no planets in the galaxy, but a huge asteroid belt has been discovered. It is estimated that the total mass of the asteroid belt in the galaxy exceeds 23 Earth masses." In Ella's report, Yan Xia thought of the debris disk of Tiancang V. The debris disk of sc-19 is even larger, and it is unknown how many billions of asteroids there are. "According to the original plan, explore the interior of the star system to observe whether there are available resources and whether it has great development value." Ella was wearing a cool liquid metal black military armor, holding a tablet in her hand to take notes, and nodded seriously. "Okay, sir." "Through preliminary observations, this star system is expected to be rich in metals, more than 25 times the five metal deposits in Tiancang, and has great development value." "The actual situation still needs to be confirmed inside the star system, but I recommend sending more soldiers out this time and be prepared to let them stay." "This is close to the middle of our journey. If possible, we should build an interstellar fortress here to redefine the interstellar scope of our Civilization Federation."
Since Ella made the recommendation, it must have been confirmed with a high probability. Yan Xia nodded: "Then do as you say." "I heard that the simulated universe has been completed in the federal capital star system and is open to academic elites in the Civilization Federation. Some people have made some changes to the structure of the propeller by strengthening the existing plan, increasing energy utilization efficiency and increasing the speed of the warship by 20%." "If there are metal resources, some can be collected to transform the current fleet." Civilization is developing, and his fleet must keep up with the pace. Even if it stays in a star system for 100 years to complete the transformation, the subsequent journey can at least save several times of time. In recent years, the progress of the Civilization Federation in propulsion has almost reached a bottleneck. Now the speed of giant warships is still maintained at about 21,000 km/s. This 20% increase can be said to be very huge, which makes Yan Xia feel that the simulation of the universe must continue. Now Ella's host is only 1% of the Dyson cloud of Tiancang V. It can be gradually increased later, and strive to achieve 10%, 50% or even 100%, so that Ella can use the energy of a star alone, and then it can build a larger simulated universe. But the energy of yellow dwarfs is still limited after all. Now the candidate energy rookie in the Civilization Federation is Sirius. Sirius is a blue dwarf star. Its mass is larger and brighter than that of yellow dwarfs. The energy released is 31 times more than that of Tiancang V. Now the most important projects of the Civilization Federation are also concentrated on Sirius. As long as the energy released by it is fully utilized, Sirius alone is enough for the Civilization Federation to reach level in energy. Four years later, the fleet arrived at the edge of the sc-19 galaxy. The reconnaissance ship in front sent back a group of pictures. It was a metal plate, about the size of a car, the whole plate was twisted, and there were traces of melting on it. "Civilization?" Yan Xia took it seriously. Could it be that there was a civilization in SC-19? This should be impossible. After four years of continuous observation, it has been confirmed that the largest planet in the galaxy is a dwarf planet about the same size as Pluto. Ella appeared on the screen and said, "This metal plate is a high-strength alloy, which is enough to make a spacecraft shell." "It is speculated that the civilization has entered level 1 and is not weaker than the former Hundred Eyes Clan."
The fleet stopped at the periphery of SC-19, and the reconnaissance ship entered the galaxy to explore. More fragments were found, and they were not scattered, but huge. In just one month, more than 1 million fragments were found, and this was found in a small area. Seeing those fragments, Yan Xia had a scene of a battleship exploding in his mind. What happened here in the past? "Yan Xia, we found the core component, a nuclear fusion device." The huge nuclear fusion device brought Yan Xia back to the shock of seeing the controlled nuclear fusion device for the first time thousands of years ago. "Have these things been tested? How long ago were they left behind?" Although metals will not oxidize in the universe, their atomic nuclei will decay. Generally, the half-life of stable elements is calculated in billions of years. As long as we speculate the initial state of these elements fusion at high temperature, and then measure the half-life, we can more accurately determine the time of their production. "About 107,000 years ago." Ella replied affirmatively. More than 100,000 years ago, humans should still be in the Stone Age. "It seems that there was a war here." The battlefield of the interstellar. Yan Xia thought that was all. But the subsequent discovery surprised him and other soldiers and officers on the spacecraft. Too many! After releasing the unmanned fighters into the entire galaxy, the speed of discovering the wreckage of these spacecrafts has increased by hundreds of times, and the number of discoveries has also increased greatly. From the original 1 million density, it has reached 10 billion density. This is not the end. More and larger debris have been discovered, each piece is tens or hundreds of meters long, mixed in the asteroid belt and become part of it. It took nearly 2 years to explore one-tenth of the area of SC-19, and the weight of the wreckage finally reached 3 trillion densities. If the other areas were also filled with these wreckages, the total weight of the wreckage would reach 30 trillion densities. This should be the amount of resources owned by a level civilization. Not only the wreckage of the spacecraft, they even found the wreckage of buildings in the asteroid belt. These buildings are definitely not built in space, but are built on the surface of the planet with soil and stone as the foundation. "According to the analysis of a large number of asteroids in the asteroid belt, the final result is that these asteroids come from three planets of different sizes." This is not an interstellar civilization encounter. It is an annihilation war launched by an advanced civilization against another low-level civilization. Such a complete destruction of a large-mass planet is at least close to or already a level 2 civilization. Yan Xia has never seen the power of the star destroyer, but he has led a passive star destroyer plan, and Proxima b was destroyed because of it. This is a huge civilization cemetery. The most common and cruel destruction of civilization in the universe.
"Who could it be?" Yan Xia had a question in his mind at this time. The nearest Level 2 civilization to the star field is the newly promoted Level 2 civilization "Civilization Federation" which has only developed for a few thousand years, the "Purple Thorn Civilization" that was trampled by the Civilization Federation, and the "Olive Branch Civilization". As for the passing civilization, it is unlikely. The general Level 2 civilization cannot wander in the interstellar space, because wandering cannot support the energy consumed by a Level 2 civilization. Yan Xia fell into deep thought.
