Let's check if there are any items that can be used immediately.
He clicked the dropdown arrow for "Electronics" and found "Portable Smart Brain, Robot Butler, Junior Super Brain, Senior Super Brain..." A rough scan revealed tens of thousands of product names.
Li Xiangdong casually took out a few Portable Smart Brains shaped and sized similarly to Hua Nation electronic watches, along with three supercomputers slightly smaller than standard all-in-one computers on the market...
Then, thinking that to understand the situation of this ring space, it would be best to find some study materials, he didn't bother searching one by one. Instead, he directly handwrote "study materials" in the search box.
Soon, the search results appeared: "Popular Science Education Study Data," "Common Astronomical Data," "Common Biological Knowledge Study Data," "Common Chemical Knowledge Study Data," "Practical Smart Brain Knowledge Study Data," "Conventional Weapon Knowledge Study Data," "Technology Tree Outline"...
Li Xiangdong chose the top five items and took out two copies of each. After a flash of light, ten packages similar to tablet computers appeared on the ground.
After over an hour of busyness, Li Xiangdong took out whatever he found through searching that he thought might be useful, as long as it wasn't too bulky. He even peeked at "Transportation" and "Weapons," discovering that there were big items like interstellar spaceships and Interstellar Warships. Unfortunately, they were too big and taking them out would definitely expose him; otherwise, he would have pulled out a few to keep around.
Still, he reasoned that ships were too large and bringing them out would cause trouble. When the time came, finding an isolated spot to conjure up a few vehicles should be fine.
After tinkering for a long time, his bedroom was piled high with various packaging boxes.
Looking at the dazzling array of treasures, Li Xiangdong gradually calmed down. It seemed his luck was very good; the ring had plenty of energy, so he didn't need to worry about it suddenly shutting down. The most crucial thing was science and technology. Only by mastering the science and technology inside the ring could he have a foundation.
Just as he was thinking this, his younger sister called him downstairs for dinner. Li Xiangdong had no choice but to close his bedroom door and go down to eat. Unfortunately, his mind was entirely occupied by the ring and the items inside, making the meal taste completely bland. He quickly wolfed down a bowl of rice, excused himself by telling everyone he needed to work on a computer programming problem, and scurried back to his bedroom.
To help him think more clearly, Li Xiangdong grabbed paper and a pen to sort out his thoughts point by point.
First, he must maintain strict confidentiality. Developing in secret while keeping a low profile was the absolute rule; until he possessed a certain level of strength, the secret of the ring must not be revealed to anyone.
Second, the ring was undoubtedly a treasure left behind by a highly developed civilization. Judging from the text displayed on the light screen, it might have some connection to Hua Nation.
Third, there were countless items inside the ring, and many of the product technologies were extremely advanced, meaning there was a vast amount to learn. However, the most important task for the immediate future was to study the Genetic Potion to improve his own physical constitution and that of his family. The average lifespan of people on the Blue Planet was very short, and it would be best to find a medicine to extend life. Only with a longer life span would he have more time to study and explore.
Fourth, after improving his physical fitness, he needed to focus on studying the computers and related software data retrieved from the ring, rapidly raising his professional level, and at an appropriate time, leading the development of computer technology on the Blue Planet to drive technological progress.
Fifth, he must avoid biting off more than he could chew. For the time being, he would stick to the points above, adjusting or postponing other issues according to circumstances.
Once his train of thought was clear, the next step was to figure out how to use the Genetic Potion to improve his physical fitness.
Li Xiangdong gathered all the study materials he had previously retrieved, took out a box labeled "Popular Science Education Study Data," and unboxed it. It turned out to be a tablet-like device with two buttons on the edge. He tried pressing one, which seemed to be the power button, and the screen instantly lit up with touch-control capabilities. Pressing the other button projected a three-dimensional image above the screen—a holographic projection, according to the title of the study material. From this, it was clear that holographic projection technology was already in common use within this advanced civilization. He found no charging port on the tablet, though, and had no idea how long it would last.
After roughly skimming the manual, he learned that it was equipped with a disposable high-energy battery capable of continuous use equivalent to over 100,000 hours on the Blue Planet—truly a technological product of an advanced civilization. If such batteries could be manufactured in reality, it would undoubtedly be a tremendously profitable business; even without manufacturing them, simply having the battery would easily make him the richest person in the world.
Li Xiangdong forced himself to regain focus and switched the tablet back to its touch-screen mode, feeling somewhat more accustomed to it. The system operations were quite similar to a smartphone, and after a few tries, he mastered the controls.
Clearly, these study materials were specifically designed for the education of minors. They introduced basic knowledge regarding cosmic civilizations.
A casual flip revealed an introduction to the classification of cosmic civilizations that was strikingly similar to the grading system proposed in a certain web novel.
As it turned out, cosmic civilizations could be divided into Planetary Civilization, Stellar Civilization, Galactic Civilization, and Multidimensional Space Civilization.
A Planetary Civilization was the lowest tier, with the defining criterion being that inhabitants could only live within their own planet, finding travel to other planets still quite difficult. The Blue Planet was currently in this stage of civilization.
A Stellar Civilization was the second tier, defined by the ability to capture at least the energy of a sun and completely convert it for personal use, allowing survival and activity within the local star system.
A Galactic Civilization was the third tier, with the criterion of breaking out of the native star system to shuttle back and forth between different star systems, and even achieving wormhole travel to leave the Milky Way. Upon reaching the third-tier civilization, one must have a preliminary grasp of time and space manipulation technology.
A Multidimensional Space Transition Civilization was the fourth tier. A primary multidimensional transition civilization could fully master spatial technology, shuttle across multiple dimensions, and explore the mysteries of the universe. An advanced multidimensional transition civilization could achieve time travel.
Comparing this knowledge with the functions of the Space-Time Storage Ring, Li Xiangdong deduced that the civilization which left behind the ring must have reached at least the peak of a third-tier civilization, or perhaps had already attained the level of a multidimensional transition civilization.
Compared to the present Blue Planet, this was an unimaginably advanced civilization—one that was somehow connected to Hua Nation, and had even let him stumble upon its space-time ring. Armed with the products and technology inside the ring for comparative study, Li Xiangdong could not help but feel his blood boil once more, as if he could already see a bright future beckoning to him.
As mentioned earlier, Li Xiangdong had been a person of immense curiosity since childhood, taking an interest in everything and always fond of asking "why" when encountering events. His reading interests were also exceptionally broad; he enjoyed both classical literature and science fiction, having read sci-fi novels like *Twenty Thousand Leagues Under the Sea*, *Foundation*, and *The Three-Body Problem* more than once. During middle school, while others found subjects like chemistry, physics, and biology dry and tedious, Li Xiangdong took a special interest in them, and his science grades had consistently remained top-tier.
