This idea was undoubtedly very audacious, yet Lu Yang already had a plan of action. For this reason, the existence of the Heavenly Demon (Primordial) was necessary for him.
"You stay here and guard this place."
Lu Yang looked at the Thunder-Commanding, Battle-Axe-Wielding, Demon-Subduing Divine General and said in a deep voice, "Draw down thunder each day to strike the seal, while ensuring no one can forcibly break it."
"Understood, by decree."
The Divine General saluted once more, then stood up. His figure dispersed into light and shadow, reforming into a talisman that landed squarely atop the mountain wall. Instantly, a bolt of lightning was drawn down from the firmament, channeled into the mountain, and fell upon the Heavenly Demon (Primordial), causing him to grunt.
"Fellow Daoist, bear with it."
Seeing this, Lu Yang smiled. This bout of thunder was unlike the previous ones. This time, what he used was the Creation aspect within the Divine Firmament Thunder concept.
