Finding a spot for the construction of the branch anchor wasn't hard considering that they were just making it for the sake of another city right now.
They could pick any spot they wanted but couldn't build it near one another or else the quality of the anchor would decrease.
After all, each of the anchors needed a lot of ambient mana.
Looking for three suitable spots, the group split apart and began the construction of the branch anchor.
The process was rather simple and the method appeared in her mind the moment she made the main anchor.
There were three steps.
The first was to extract a bit of energy from your main anchor. The second was to enhance it with your own power, hence why many Queen's would be weakened after the first branch anchor. They'd need to wait for the power to return to them over time as more people live in their city.
