Xiao Ran was quite experienced when it came to the conditions for acquiring a Faction Territory. One particularly important point was that, generally speaking, a force established by participants themselves after entering a world had no way of becoming a Faction Territory.
Just like in 0079 World, if he had not obtained the world core—the Original Constitution—then even if he had merged Zeon and the Federation together in that world, it would have been completely useless. Unless he had done so openly and legitimately, without using any means against the current faction.
New Jior was now much like 0079 World had been back then. The only thing missing was the world core.
If Odou City, which had truly developed and manufactured the VVV Mecha, was the world core, then Xiao Ran had already come into contact with it. The only difference was that he had been transported there and had not actually found Odou City's true location. But that should naturally have had no effect on whether he obtained the world core. In other words, the mysterious Odou City was not this world's true core at all.
Then what exactly was the true world core? Xiao Ran had no clue whatsoever. In his view, Demon Envoys definitely counted as one of this world's core elements. So many things had happened in this world because of Demon Envoys. The development of the Dyson Sphere and things like the Rune Engine were all inseparable from them.
Aside from Demon Envoys, there were the VVV Mecha and Odou City. Xiao Ran had come into contact with all three core elements, yet he had never received any hint concerning the world core. If none of the most important things were it, he could not expect to casually pick up a stone from the ground
