Exactly because Mars is Yan Fei’s defense core, he did not build large-scale defense weapon arrays on Earth. However, to monitor Earth, he will build weapon turrets on the Moon aid at Earth. Then, on the outskirts of the Asteroid Belt, Jupiter’s Satellites, Saturn’s Satellites, and other strategically important planets, he will construct powerful energy turrets. If there is indeed an invasion by foreign enemies, these weapon turrets will serve as defense arrays to protect Mars and Earth. Even if they cannot completely stave off the enemy invasion, they can at least buy Yan Fei ti to evacuate personnel from Earth and Mars, avoiding significant losses to Earth humans.
Therefore, in the following period, Yan Fei went full force, starting to build various weapon platforms within the Solar System, crafting his own defense system...
———————————————————————————
After several years of large-scale mineral resources extraction, Spirit Divine Star underwent a massive shape change. The previously nearly round star body had been flattened, turning into a flat rocky land in the center. This rocky land is connected to the Dreamland Cave World through a second space channel, exchanging goods and resources between them.
This land floats in space, flying in a certain direction, with many slting factories and production facilities already built on it. Mineral resources extracted from the nearby Asteroid Belt are transported to it for slting. Yan Fei specially constructed a large space battleship production factory on it, starting to produce warships suitable for space combat.
Previously, to allow for Yan Fei’s Drone Upgrade, Yang Qi designed a mature space battleship. But at the ti, due to a lack of production capacity, Yan Fei couldn’t produce this kind of space battleship, only letting them exist on blueprints. However, after Yan Fei completed the Drone Upgrade and gained super production capacity, especially since the core components of space battleships could be produced by dium-sized production workshops, Yan Fei for the first ti had the capability to produce space battleships according to blueprints.
After several years of construction, this space battleship production plant has been completed, and from now on it can produce space battleships belonging to Dream Island. Although this factory is a fully smart, unmanned production workshop, because these space battleships are overwhelmingly large, even if its production capacity is maximized, it would still take at least three years to produce one. Adding post-crew tests, and familiarization with the warship operations, it would take at least another three years to fully form combat power. That is to say, even if Yan Fei starts production now, it would be at least six years before he could obtain a space battleship ready for actual combat.
But this is the first type of powerful space battleship produced by Dream Island that ordinary warriors can operate. They have no quantity limit, no energy limit, and no operation distance limit, so as long as Yan Fei doesn’t lack resources and has enough warriors, he can continue to explode troops, enhancing his strength. In an extre case, these space battleships could all be modified for smart control, so even without sufficient control personnel, Yan Fei could have an endless number of space battleships.
However, the production capacity of these space battleships still has certain problems, and to fully produce them will take a long period. But the future is bright, once conditions are t, and Yan Fei starts exploding troops, even without the Drone Avatar, Dream Island will beco a force in the universe.
Whether it is exploding troops or constructing the Solar System Defense System, both require a vast amount of ti and adequate resources, not sothing that can yield results in a short period. Yan Fei also cannot wait here forever, so he starts focusing on investigating the Solar System environnt, getting ahead of the ga, preparing for potential future intergalactic wars.
Yan Fei, much earlier, released a large number of quantum satellites that are flying toward the outer solar system at near-light speeds. Although most were destroyed by high-speed collisions with obstacles during flight, Yan Fei quickly replenished them, ensuring they could enter the universe from different directions.
Three years later, Yan Fei’s quantum satellites have reached nearly three light years away from Earth in the farthest reaches. So directions of quantum satellites still have gaps, but Yan Fei, in general, has learned about the cosmic situation within a three-light-year radius of the Solar System through the quantum satellites. The Artificial Intelligence "Dream" has also taken over these quantum satellites, monitoring these star domains at all tis. If any abnormal situation occurs, it will imdiately notify Yan Fei.
That is to say, through quantum satellites, Yan Fei effectively obtained at least a three-year warning period. If an enemy does invade from outside the Solar System, Yan Fei will imdiately know and have three years to prepare counterasures. In three whole years, even if unable to defeat the invading enemy, Earth’s and Mars humans’ absolute safety can at least be guaranteed.
Yan Fei is about to begin exploration of the universe surrounding the Solar System; he must first familiarize himself with the geographical situation, to know oneself and the enemy, to be victorious in every battle...
The knowledge inherited from the Cosmic Human Soul tells Yan Fei that in the universe, due to the restrictions of cosmic rules, no matter what the object is, its flight speed has an upper limit, only infinitely approaching the speed of light, and absolutely cannot break the speed of light barrier. This is also the fundantal reason why Yan Fei’s quantum satellite speed can only infinitely approach but not exceed the speed of light.
However, the universe is so vast that if only traveling at speeds near the speed of light, it might take a lifeti to leave a star river, let alone traveling between star rivers. So cosmic creatures utilized their intelligence to research two types of superluminal flight technologies. The first technology is curvature navigation, and the second is wormhole travel.
Curvature navigation involves creating a spatial depression in front of the spacecraft, generating an effect similar to gravitation, with the spacecraft sliding towards this spatial depression. This process can be likened to the spacecraft constantly falling towards a gravitational center within a gravitational field, only the gravitational center keeps moving forward with the movent of the spacecraft. Additionally, negative spatial curvature is created at the spacecraft’s rear, pushing the spacecraft rapidly forward in a forward-pull rear-push manner.
The essence of curvature navigation is to bend space greatly, thus shortening the distance between two locations, achieving rapid transit from one place to another. Theoretically, the speed of curvature navigation can exceed the speed of light, even many tis over, but this is rely due to space bending, not representing that its flight speed has truly exceeded the speed of light.
Wormhole travel technology involves expending a large amount of energy to forcibly open a temporary connection channel at two different Spatial Nodes. The spacecraft entering this connection channel will appear in another space, traversing vast distances in an instant. In terms of phenonon, wormhole travel technology has surpassed many tis the speed of light, but in essence, its speed still cannot break the light-speed limit.
From an essential standpoint, these two superluminal flight thods do not have a hierarchical distinction; both are thods for ultra-long-distance travel. However, in detail, there are significant differences between the two, leading most cosmic civilizations to choose curvature navigation while seldom using wormhole travel technology.
Although curvature navigation can be realized, it has a prerequisite; it must be within a vacuum, with no obstacles on its flight route. Once an obstacle appears, even if it is very small, it might cause the warship to disintegrate and explode. Therefore, curvature navigation is only suitable for absolutely vacuud universe travel; once it enters a stellar system, it dares not use such a flight thod. Because within a stellar system, massive celestial bodies and nurous teorites and cosmic dust abound, using curvature navigation in such an environnt is a dead end.
But in the universe, various vacuum environnts are the most abundant. Conversely, environnts similar to the interior of a stellar system are relatively rare, so cosmic civilizations commonly use curvature navigation to traverse long distances. Once they enter a stellar system, they slow down and use other thods to proceed inside.
Wormhole travel technology is completely opposite; it does not have this restriction. Even if there are giant star bodies in the middle of a wormhole transition, as long as the entry and exit ends of the wormhole are not within the star bodies, it can still safely conduct wormhole travel. Thus, wormhole travel can be used completely within a stellar system, as it is not afraid of obstacle hindrances.
