The Six Fold World Destroying Thunder contained a significant amount of yin energy. After consuming this thunder, the chill around Rainbow intensified, and its gaze became even colder.
This Six Fold World Destroying Thunder provided substantial nourishment to it, not only deepening its cultivation foundation but also triggering a chemical reaction with the bloodline of the Sky Piercing Black Eagle within Rainbow. This led to the birth of Skill 4: "Ghost Wail."
Ghost Wail is a terrifying sonic attack. When unleashed, the sound resembles weeping and lamentation, as if ghosts and deities have descended, capable of inflicting significant damage on the target's mental resolve.
With the acquisition of Ghost Wail, Rainbow's overall capabilities have significantly enhanced.
Soon, the fourth heavenly thunder was ready. With its tenacious will, Rainbow successfully withstood the onslaught of the fourth heavenly thunder and devoured it.
