With a crisp crack, the entire space where Li had been standing began to shatter. Li could clearly sense that the aura emanating from that spot belonged to dozens of worlds. This guy had actually opened more than twenty random spatial rifts at once, trying to tear Li apart in an instant.
Fortunately, Li's movements were swift enough. Otherwise, he would surely have fallen victim to one of Zeref's tricks just now.
Of course, being able to open spatial rifts did not mean one could travel through space. First, one had to grasp one's coordinates within the current space. These coordinates were not something as simple as X and Y, but an extremely complex functional relationship—or at least, that was the system of measurement developed by the magical civilizations Li knew of.
But without a doubt, if an ordinary person were asked to memorize the coordinate function for a single spatial coordinate, it would take at least a year even to barely commit it to memory.
Li had always had the system help him record those spatial coordinates. At the same time, the system possessed another powerful function: while it had already recorded countless spatial coordinates, it could also explore new ones.
And even after learning a space's coordinates, entering that space still required a vast amount of energy to break through the crystal wall. This was the stumbling block that stopped countless gifted scholars of spatial studies.
Why call it a stumbling block? Because so-called geniuses were often those who became immersed in scientific research and lost their pursuit of power. They lacked strength, yet genuinely sought to explore other spaces and break through spatial crystal walls.
Moreover, even if one entered another world, there were several problems. First, one's power might not conform to that world's laws of
