Over the past few years, Han Sen had studied and learned much alongside Bai Yishan. He spent most of his time researching the powers of the Coin Toad's energy flow and developing Saving Money.
Creating hyper geno arts was not easy, and he had only managed to create one during all that time.
What he often referred to as "Make It Rain" was not a proper skill, just a barrage technique he employed. Saving Money was different to this, as it actually involved a warping of the powers that would be used.
Humans could create and use powers that were complex in their employment. The intricate nature of human skills was why they took a long time to master, but it was also what gave them an edge against spirits. Spirits were a lot more basic, and their power was often derived from simple strength. If all battles were a direct collision of strength, spirits would almost always win.
