After Long Xuan completed his initial conceptualization of the "Five Elements Reversal Grand Formation," a model formed in his mind. He quickly started writing based on this model.
All of the formations mentioned above were of his own creation, but there were too few of them. Truly formidable composite formations always integrate thousands of various formations, covering a wide range of functions.
The few formations he created himself were far from meeting the standard of a composite formation. Once the formations reach a level of intricacy, they become insufficient.
Thus, he had to incorporate a large number of already existing formations into his composite grand formation.
Thousands of formations—creating just a few of his own would be sufficient. If he had to create them all from scratch, it would be exhausting.
What he needed to do now was figure out how to piece together these thousands of formations. Since he was working on a microscopic-level formation, the number of formations he needed to integrate far exceeded that of a standard composite formation.
Of course, the more formations a combination formation contains, the stronger it becomes, which is also the advantage of the microscopic school of formation.
However, the more formations there are, the more prone the combination formation is to vulnerabilities. This would require immense computational power and consume a considerable amount of his time.
That cavern lord was undoubtedly a rare formation master. The formation legacy he left behind was extremely powerful, and there were numerous formation diagrams he left as well.
With his current knowledge of formations, and the aid of the error-correcting tool, it wasn’t too difficult for him to develop a combination formation with very few flaws.
However, time was of the essence. Setting up such a massive combination formation was too time-consuming, so he needed to move in as soon as possible; there wasn’t time to wait.
Thus, he decided to temporarily set aside the study of original formations like the "Rubik’s Cube Grand Formation" and "Teleportation Formation," as they were not that important. As long as the formations he set up could provide a place to live, the remaining time-consuming details could be studied after moving in.
To speed up the process, Long Xuan decided to leave many things unfinished for now, focusing only on the "Rubik’s Cube Grand Formation" as his original creation. The rest of the tens of thousands of formations would be ready-made ones, simply pieced together. His task was merely to fit the pieces together like a puzzle.
With the help of his golden finger, perfectly piecing these formations together wouldn’t take too much time.
As a result, it took him only eight months to complete the formation diagram for the Five Elements Reversal Grand Formation.
The three core elements of the formation—the formation base, formation eye, and formation guide—were all successfully completed.
Of course, this was only a semi-finished product that was functional for the time being. He would need to continually fill in the content afterward.
A fully completed Five Elements Reversal Grand Formation would take far more than a year to finish.
As his cultivation level increased, he would need to continually refine the formation.
The Five Elements Reversal Formation was a massive project that would require a lifetime of refinement.
Since his formation patterns were scaled down versions, the number of formations he would need to use in the future could reach into the millions or even tens of millions, making the upper limit of this formation terrifyingly high.
After repeated experiments in the Origin realm, he confirmed that microscopic formations were indeed achievable in this world, but only when the formation patterns were reduced to about one-hundredth of their original size. Any further reduction would render the formations ineffective.
But even reducing them by one-hundredth was enough to satisfy Long Xuan.
To say nothing of reducing them by one-hundredth, just reducing them by tenfold would be enough to crush the mainstream formations of this world, so what more could he want?
The combination formation he designed might not be the most powerful in this world, but because of the sheer number of formation patterns he etched, even if there were some flaws, his Five Elements Reversal Formation would still rank as a world-class formation.
While he didn’t dare boast that it was an peerless deadly formation, Long Xuan was confident that his Five Elements Reversal Formation could certainly be considered a deadly formation. It wouldn’t be something that an average formation master could easily break.
If a formation master wanted to break his formation, sorry, but they would first have to find where the formation patterns were hidden!
The Five Elements Reversal Formation was a massive chain formation, with the forces of the five elements interlocking. Tugging on one part would affect the whole.
Unless someone understood how to dismantle the power of the five elements, this fierce formation was unsolvable.
If a powerful being tried to break the formation by brute force, given that the formation eye was pressed down by a spiritual spring, they would need a force capable of shaking the heavens and earth; otherwise, the formation would remain unbroken.
Hidden within this formation, Long Xuan felt that he could sleep peacefully.
