After saying that sentence, the unknown entity added another line: “You can call me Taihao.” The term Taihao carried a special meaning within the Earth Civilization. Taihao, also known as Fuxi, was, in Chinese mythology, considered the ancestor of humanity. “Currently known, spatial broadcast has some kind of automatic translation function. It can automatically translate information into the most appropriate terms based on the data in my mind. Since it translated this term into Taihao in my mind, there must be a reason for it.” “But, how could it be the Taihao Civilization? How could it possibly be the Taihao Civilization!” Upon hearing this term, Xiao Yu was extremely shocked. “From what I know so far, the Taihao Civilization has already existed in the Milky Way Galaxy for at least several hundred thousand years. Hundreds of thousands of years ago, they imprisoned the White Dwarf Alien Beast. Moreover, within their classification system, the White Dwarf Alien Beast was labeled as Alien Beast Type-Three. This indicates that there must have been Alien Beast Type-One and Type-Two before it. Just how many eras they have existed for is even harder to predict. But this guy, he just arrived from the Large Magellanic Cloud? How could he possibly be from the Taihao Civilization?” “Is he lying to me? What reason would he have to do so? Besides, if he truly wanted to deceive me, why reveal the name Taihao? Wouldn’t fabricating a random civilization name be more logical?” Xiao Yu thought rapidly. “Have you... have you ever been to the Milky Way Galaxy before?” Xiao Yu asked cautiously. “Oh? Do you have any doubts?” Taihao asked with some interest. “I just arrived at the Milky Way Galaxy less than ten thousand years ago. The emptiness of the Milky Way far exceeded my imagination. You are the first intelligent lifeform I’ve encountered in ten thousand years.” “Empty?” Xiao Yu gave a bitter smile and thought to himself, “Empty? Ever since leaving Earth, I’ve encountered so many civilizations... Hm? No, wait. Perhaps the Milky Way really is empty. It might just be because someone was manipulating things from behind the scenes that I encountered so many civilizations.” “It’s like this,” Xiao Yu thought for a moment, then said, “I once encountered a powerful Alien Beast. It said it was the Taihao Civilization that imprisoned it atop a white dwarf star.” “That’s normal,” Taihao replied with a full smile. “Just as technological civilizations exist within the Milky Way Galaxy and also exist within the Large Magellanic Cloud. Similarly, the Taihao Civilization can exist both within the Large Magellanic Cloud and within the Milky Way Galaxy.” “So that’s how it is...” Xiao Yu was momentarily stunned before saying, “It turns out that the Taihao Civilization, like technological civilizations, is a broad classification for a type of civilization.” “Correct,” Taihao replied, “but there are also some differences. Based on your description, the Taihao Civilization mentioned by that Alien Beast seems to be a Type D Taihao Civilization. I belong to the Type C Taihao Civilization. I don’t know if that Type D Taihao Civilization still exists, but if it does, I would like to go and have a fight with it.” “What exactly is the Taihao Civilization? How is it different from technological civilizations and Alien Beast Civilizations?” Xiao Yu asked. Having finally encountered a powerful civilization that had expressed some goodwill toward him, Xiao Yu naturally didn’t want to let this opportunity slip by. Every piece of information he obtained during this period of interaction could potentially save his life during the long times to come. “The Taihao Civilization is merely a civilization that attempted but failed to evolve into a Level 7 Civilization,” Taihao transmitted information with a tinge of sorrow. “I used to be a Level 6 Alien Beast. In the process of attempting to evolve into a Level 7 Alien Beast, I failed, and became like this.” “In the universe, who can say anything with certainty? Destruction leads to rebirth; rebirth leads once again to destruction. The Taihao Civilization walks the edge of destruction, and that’s why it’s called Taihao.” “I don’t quite understand,” Xiao Yu said. “You don’t need to fully understand. When you reach this stage, you will,” Taihao sighed. “Your type of existence is quite interesting, but don’t worry. Your existence holds no reference value for me, so I will not harm you. Ah, after billions of years, having someone to talk to is already a blessing.” Xiao Yu fell into silent contemplation. “The unknown entity that has been silently watching me from behind all this time has a high probability of being the Taihao Civilization that imprisoned the White Dwarf Alien Beast and even indirectly caused that Earth girl’s tragic suicide. But... since it is from the Taihao Civilization, it couldn’t possibly be a Level 7 Civilization. Nor would it be significantly stronger than the Taihao I’m currently encountering. In other words, it wouldn’t have the ability to control this Taihao. Therefore, the explanation for my current situation likely falls into three possibilities.” “First possibility, it’s lying to me for some unknown reason.” “Second possibility, if what it says is true and the information is accurate, then perhaps our meeting really was just a coincidence, and the so-called manipulator behind the scenes doesn’t exist. But having coincidences happen once is understandable — could it really happen so many times?” “Third possibility, it is the Taihao Civilization that imprisoned the White Dwarf Alien Beast and has personally intervened to rescue me from the information storm.” “The second possibility seems most likely. The information is insufficient to continue analyzing further. Ah well, I’ll just take it one step at a time,” Xiao Yu concluded. Xiao Yu then asked another question: “You said you are a Type C Taihao Civilization? How are the Taihao Civilizations categorized?” “That classification system is something created by technological civilizations. I’m not familiar with the specifics,” Taihao answered. “The universe is so vast. Whether a Level 7 Civilization truly exists, no one knows. At least, in my over two hundred million years of life, I have never seen a Level 7 Civilization, nor even heard rumors of one. After reaching the peak of Level 6 Civilization, I chose space as my path of evolution, but still ultimately failed. As a result, I now exist in a half three-dimensional, half four-dimensional state. I am attached to this three-dimensional space while simultaneously existing partially within the fourth dimension.” “Um... how should I explain it... if we use two-dimensional and three-dimensional space as an analogy, it’s like lifeforms without the ability to fly existing on the surface of a planet. They are attached to the two-dimensional surface of the planet but their bodies are still in three-dimensional space. Anyway, beings like me are categorized by technological civilizations as Type C Taihao Civilizations.” This explanation was easy to understand, and Xiao Yu immediately grasped it. “You... have obtained a fourth spatial dimension but cannot move freely within it?” Xiao Yu asked hesitantly. “Kind of like a lifeform that has gained height but still can’t jump or crouch, stuck moving only along the surface?” “Smart — that’s exactly it,” Taihao answered with great approval. “I cannot fully return to three-dimensional space, nor can I fully traverse four-dimensional space. What you are standing within now is the shadow of my four-dimensional body projected into three-dimensional space.” Four-dimensional space only existed in mathematics. As three-dimensional beings, humans could not have an intuitive understanding of four-dimensional space. However, it could be glimpsed through analogies involving two- and three-dimensional spaces. A dimension was simply a concept in mathematics describing how many parameters were needed to locate a point in space. One parameter for one-dimensional space, three parameters for three-dimensional space. Suppose a space is a straight line — clearly, it needs only one parameter to locate a point, making it one-dimensional. A plane needs two coordinates to pinpoint a point, making it two-dimensional. Our three-dimensional space requires three coordinates. Four-dimensional space, then, needs four coordinates. “Taihao said he had obtained a fourth dimension but could not move freely within it. It could probably be understood like this...” Xiao Yu thought. “Imagine a flat being with only length and width but no height. Suddenly, it acquires height and evolves into a three-dimensional being. However, the evolution is incomplete — it can’t leave the surface. It has height but cannot jump or crouch... its third dimension is fixed and immobile. That situation is somewhat similar to Taihao’s.” In simple terms, Taihao’s current state was like a car in three-dimensional space that could turn left and right but could not ascend or descend. Although it had height as a third dimension, it could only move across the two-dimensional plane. Similarly, Taihao had acquired a fourth spatial dimension but could still only move within three-dimensional space. “What does four-dimensional space look like?” Xiao Yu asked cautiously. “I can’t describe it to you in full detail. But I can let you experience it temporarily,” Taihao replied. “Although four-dimensional space is fascinating, after seeing it long enough, it loses its novelty.” “Really?” Xiao Yu grew excited. “In our universe, three-dimensional space is the mainstream. All matter exists in three dimensions. In four-dimensional space, it’s just emptiness,” Taihao sighed and said, “You already possess a four-dimensional perspective. Use fourth dimensional vision to reobserve your world. You only have five minutes — I don’t want to expend too much energy for this.” At that moment, all the instruments under Xiao Yu’s control seemed to flicker. Xiao Yu heard Taihao’s words, but he didn’t pay attention — because he was completely stunned by the miraculous scene unfolding before him. What appeared before Xiao Yu was a dazzling, indescribable world.
