The cross blade was extremely beneficial to any realm in the cultivation world. Just its location was extremely attractive to the other realms.
The cross blade was located at the border between the array world and the cultivation world. It was a little further from the cultivation world and a little closer to the array world, but this position was very important to any world.
Because it was at the border of the two worlds, neither the array world nor the cultivation world dared to send too many forces there to deal with them. If they did, it might cause a violent reaction from the other world. It was also for this reason that the pirate paradise had always existed.
However, the location of the pirate's paradise was very useful for both the cultivation world and the machine array world. It was also very useful for the other worlds. It was for this reason that the pirate's paradise had so many forces, and it was even now called a small cultivation world.
