The space above the Sovereign Sea tore apart, as formless lightning whizzed down. Thunder sounds roared and resounded in the Sovereign Sea, causing boisterous waves. It felt almost like it was the destruction of the entire world.
As Mu Chen looked at the scene before him, he turned grave. The formless lightning kept falling, like meteorites, into the Sovereign Sea.
Plop! Plop!
Vast spiritual energy surged like billowing waves. Wherever the Netherworld Thunder Heart fell, the purple spiritual energy would melt and become formless. The sparks of purple fire died out, fizzling under the attack of the formless lightning.
The Sovereign Sea, which had previously been filled with purple lights, suddenly filled with all different colors within a short span of time. All of these changes were direct results of the attack of the Netherworld Thunder Heart.
