Rahu Demon Abyss, at the entrance of the massive chasm at the valley's bottom, had already turned into a battlefield of flying flesh and blood.

Led by Elder Fang, a group of powerful cultivators fought desperately to hold the line, ultimately playing their part in causing heavy casualties to the first wave of Rahu Demon Clan, forcing them to slow their assault.

Meanwhile, thousands of miles away, an innate Harmony treasure serving as a camp suddenly erupted with a vast golden radiance. Countless powerful cultivators surged forth, creating a magnificent formation array spanning billions of miles centered around the underground chasm.

As soon as the array was completed, various deadly and ruthless methods like the Primordial Magnetic Evil Light, Five-Flavored Divine Fire, Vajra King Demon-Slaying Heavenly Thunder, Weak Water Yin Thunder, and Yin-Yang Annihilation Divine Thunder were unleashed without restraint.
