As Yu Qingtan plucked the strings of the Green Jade Zither with his fingertips, a melodious yet sharp melody instantly spread out, piercing through the swamp and reaching deep underground.
This melody was unlike any sound of the mortal world. It seemed to penetrate the boundaries of matter, striking directly at the depths of the Nether Shadow Snake's soul.
In the swamp, the previously calm and stagnant mud began to churn, and strands of Nether energy stirred more violently under the influence of the sound waves. Indistinctly, the massive body of the Nether Shadow Snake twisted and struggled under the mire, seemingly resisting the heart-palpitating musical attack.
