Final blow of an Elemental law
The Major heavenly Wind Law, one of the elemental laws whose technique is widely spread across all planets
The elemental laws, such as wind, water, lightning, and other visible elements around us, affect the bodies of living beings directly from the moment of their birth, and all mortals know them, even if only superficially. Even a mortal will know the way water moves, its shape when it freezes, and so on~ and this facilitates the learning process compared with hidden laws, such as the law of Reverse Expulsion, based on which Robin designed the gravity bracelet.
Therefore, cultivating these elemental laws is easier, the success rate is greater, and results appear much faster compared to the rest of the hidden or unnatural laws.
