According to the system's introduction, fusing characteristics required potential points. When fusing a characteristic, it required two potential points.
When fusing the second characteristic, four potential points were needed. And so on, the potential points needed for each additional characteristic would double.

Ning Shi also wanted to wait for the mecha to be built before fusing the brain nucleus characteristics.
