During the first and second steps of cultivation, cultivation techniques and martial skills each had four stages: lower, middle, upper, and extreme. However, once a practitioner reached the third step of cultivation, things became less complex.
Now, cultivation techniques and martial skills were uniformly classified into ranks: Heaven Immortal Rank, True Immortal Rank, Golden Immortal Rank, Immortal Monarch level, Immortal King Rank, Quasi Immortal Emperor Rank, and Immortal Emperor Rank.
Han Li's highest martial skills were previously only at the Heaven Immortal Rank, such as the Seven Destructions Undying Body, the Taiyin Extinction Finger, the Nine Heavens Steps, and so on. The Flat Sky Quadruple was the first True Immortal Rank martial skill he mastered.
