The Ethereal Hidden Injury Fist, at its first level, possesses the power of a Mysterious Tier Basic martial art, requiring a cultivation base of at least Fifth-tier Martial Master to practice. The second level reaches the difficulty of a Mysterious Tier Intermediate martial art; the third level reaches the Mysterious Tier Advanced level; the fourth reaches the peak of the Mysterious Tier; the fifth level reaches the difficulty of an Earth Tier Basic martial art; the sixth level is at the Earth Tier Intermediate level; and the seventh level reaches the Earth Tier Advanced, and even peak Earth Tier level.
With each level of practice, an additional layer of attack is continuously added. Like waves of water, they stack one upon another until the seventh level of power is unleashed, at which point the maximum potential of the Ethereal Hidden Injury Fist is fully revealed.
As one advances through each level, a corresponding doubling of the shock effect occurs, meaning the lethality produced doubles as well. Simply put, mastering the first level brings a doubling of attack power and lethality; reaching the second level brings a fourfold increase in attack power and lethality.
