Not everyone could have a godly technique on the level of the [Simulating the Hands of a Deity]. In truth, Dyon had created this technique himself and he had never shared it with anyone, not much unlike he had created the split minds technique when he was still a youth in Focus Academy.
Of course, he wasn't aware of this fact until he awakened his memories once more. But, that was hardly a point of emphasis now. The important point was that even though he had kept a technique like this to himself, it didn't mean that others hadn't come up with solutions of their own.
The phantom pill was one such example and was even the most widely accepted due to its unique aid during training.
It was actually inappropriate to consider the phantom pill a technique as there was no one way to complete it. It was better to consider it as a mode of training.
