Ye Qiuli's behavior of supplementing and perfecting the earth-centered star map in the spaceship brain database and his own star marker while flying is actually carrying out this kind of work to expand the map, as long as it is smoothly connected to the Xiuzhen Realm star map that was originally stored in the star mark, the entire star map will immediately have a complete effect on him, and he will not be able to use it at all as he is now, although he is very greedy.

The reason for this problem is that the coordinate systems of the two sets of interstellar coordinate maps he currently has are completely inconsistent, and they are not matched at all, and if he wants to use the original star map in the star marker, he can only connect the star map he is building with it and unify the coordinate systems of the two.

At that time, Ye Qiuli could choose to use either the coordinate system common in the cultivation realm or the coordinate system with the earth as the origin, and there was not much difference between the two methods. This is like the GPS global positioning system of the United States and the Beidou navigation system of China, the coordinate systems of the two are absolutely different and completely different, but it does not affect their use on the earth, and they can accurately determine their specific location based on it.

Among them, the most critical element is to have an overall unified coordinate system, which can be used to judge the specific position of oneself, as for what is used as the basis for judgment, it is not very important, as long as it is useful. The same is true of the star map of the cultivation realm, no matter what is used as the origin, the most important thing is to be able to locate your exact coordinates in detail, and everything else can be ignored.

Thinking that he would soon be able to grasp the entire map of galaxies covering the entire cultivation realm after only a period of hard work, Ye Qiuli's heart immediately swelled with unspeakable surprises, and the whole person became a lot more excited, and he felt more and more that the few stars in his hand were lovely. Now recalling the scene of discovering these superb treasures at that time, he still has a feeling of overjoy.

Indeed, after opening the Liuyun Immortal Ring for the first time to check the treasures in it, and finding that there were no top-level magic weapons suitable for his physique, and some other treasures and half-immortal-level treasures were all destroyed, Ye Qiuli had long since stopped having too many expectations for the ready-made treasures in it, and instead decided to refine the top-level magic weapons that he could take advantage of.

It's just that he didn't expect that when he was looking for the star map left by Lu Yan, he actually found several top-level stars in the Liuyun Immortal Ring one after another, and then found the entire galaxy map covering the entire cultivation realm in those stars, which really surprised him for a while.

In a cultivator's cultivation career, there are several pieces of equipment that are absolutely indispensable. Among them, the first is storage equipment, Qiankun bags, storage belts, storage bracelets, and storage rings all belong to this category, without them, cultivators can hardly leave the door. And the second essential thing is the star map, without them, even if the cultivator has the ability to travel far from the stars, he will not dare to leave the planet he is on too far, at most, he will wander around a few nearby planets, and his vision and space will be greatly limited.

The star map, the full name of the interstellar coordinate map, is a three-dimensional interstellar map covering countless planets, and it is also the only basis for cultivators to identify the direction and judge the star path in the vast universe. In the absence of a star map, once a cultivator loses his way in the universe, the consequences will be extremely terrifying, and it is almost impossible to find the planet from which he started. In the vast sea of stars, the appearance of all the planets looks similar, and there is no way to accurately judge the distance and direction between each other.

Similar to most of the materials in the cultivation realm, the star map is also carried by magic weapons, just like the map on the earth is carried by atlases or computer data, and it is not something that exists alone. Moreover, because the interstellar coordinate map is information that exists in a three-dimensional form, unlike the maps inside the planet, which are all flat, the magic weapon that carries it also has to be specially refined, and it is also a relatively rare thing in the cultivation realm.

As long as you find the teleportation array and put the magic weapon carrying the star map into a specific position, with the mysterious connection between the two, you will soon outline the three-dimensional teleportation route map between this teleportation array and all the teleportation arrays that can be connected within the magic weapon, and the cultivator can easily judge the location and distance of the nearby planets connected by the teleportation array as long as they follow this road map.

After finding other planets connected to this planet with teleportation arrays, if the cultivator's cultivation is enough to be able to lock on to that planet from afar, he can naturally fly directly over, except that he needs to have a distraction period or more and it takes a lot of time, but there is no big problem. If the cultivation is not enough or you are in a hurry, then you will have to spend the spar to activate the teleportation array and teleport directly. If you don't even have the spar to activate the teleportation array, then I'm sorry, go back and dig up enough spars to start again.

In this way, every time you encounter a teleportation array, mark the route and coordinates, record the specific situation of the planet where it is located, and after repeating it many times, you can naturally outline a detailed three-dimensional map inside the magic weapon that carries the star map. If the magic weapon is powerful enough, and the three-dimensional map outlined is wide enough and detailed enough, it can immediately reproduce the entire interstellar map of a certain star field in miniature, and even if it is a little more powerful, it can even reproduce the entire map of the star field of the entire Xiuzhen realm.

This is the main principle of using the teleportation array to mark the coordinates of the planet, and then generalize and evolve into the interstellar map of a certain star field. First, mark the main planets with teleportation arrays, and use them as the fulcrum and nodes of the entire star map, and then continue to mark the size, orientation, distance and other coordinate data of the planets near the teleportation array according to their own exploration, which is slowly enriched and improved, and finally becomes the basis for judging the interstellar coordinates of any planet.

In the Xiuzhen realm, there are two main magic weapons that carry interstellar maps and mark the coordinates of the planets, the first is the star map, and the second is the star mark. The functions and principles of these two magic weapons are the same, the difference is that the number and detail of the interstellar coordinate maps stored in each are different, just like the difference between a paper world map and a global positioning system carried by a supercomputer, and the difference in the breadth and depth of the information recorded by the two is very significant.

In addition to these two interstellar positioning tools, there is also a fixed astrolabe used by immortals, and the quality is many times better than these two. It's just that because their number is too scarce, they are basically worn on those immortals who come down from the fairy world, and the vast majority of cultivators have never even seen it, so in the cultivation world, when it comes to interstellar positioning tools, the fixed astrolabe is usually excluded, and the most commonly used are star maps and star markers.

The interstellar map recorded in the star map is very broad, mainly marking the coordinates of some key areas in the cultivation realm, such as some large cultivation planets, some famous resource planets, and the location of the major holy places and major sects in the cultivation realm.

It's like a rough map of the large and medium-sized cities and the main roads between them, although the markings are relatively rough, but the main things have been recorded, and if you don't leave the mainstream cultivation realm, you can go back and forth through the teleportation array all the way, and there is no problem in using it. This kind of magic weapon is mainly used by ordinary cultivators, and it is relatively common, as long as the financial resources are sufficient, it can be easily bought in some large magic weapon stores.

Of course, this is a relatively common star map, marking some broad and general things, focusing on the overall grasp, large and complete, and there are also some star maps that mainly mark the detailed interstellar coordinates of a small area in the universe, just like a local high-definition detailed map of a certain area on the earth, small and fine. This kind of star map is mainly used by local cultivators, and it is also relatively common, as long as there are enough crystals, it is easy to buy.

Seriously, the relationship between these two star maps is like a map of the world on the earth and a detailed map of a city, each made for different needs, although the two sides are related, but the difference is even greater, and they are basically independent of each other. And if you want to make them completely combined, there is both an overall grasp and a partial detailed explanation, it is not completely impossible, and the star is a magic weapon born specifically for this purpose.

Star is a more advanced interstellar positioning tool than the star map, which not only records more and more detailed interstellar coordinate information, but also has more powerful functions, has many unique functions, and is more convenient and faster to use. This kind of magic weapon is very difficult to refine, and it is very rare in the cultivation world, and it is mainly used by those cultivation masters. Of course, if an ordinary cultivator has enough financial resources and a certain amount of luck, he can also buy a star.

The reason why the cultivators mainly choose to use stars to record interstellar coordinates is not to show off and show off their differences, the key reason is that they are strong and can move freely between different galaxies or star fields. Inaccessible or very dangerous existence, need to record all kinds of important information, the amount of data is very complex and huge, ordinary star maps simply can't fit, you have to use specially refined stars.

Star maps and star markers are the two magic weapons of interstellar positioning, very similar to the difference between general civilian maps and strategic-level military maps, the two sides are not at the same level at all, and the specific information they can provide is not the same at all, and the performance is also far from the same.

However, just as civilian maps can be supplemented and refined, and eventually become military maps, military maps can certainly be used for civilian use, excluding the differences between the two magic weapons in terms of storage capacity, display capacity, ease of use, etc., there is no absolute difference in the specific information content stored in the two internals. If the interstellar coordinate information recorded in all the star maps in the cultivation realm is summarized, and the information in all the star symbols is also summarized, the final result will definitely be similar, and it is a collection of all the planet map information that the cultivator has ever set foot on.
