The third spirit infusion appeared. In the pitch-black night sky, the colorful spirit energy pillar was as charming and dazzling as fireworks. In the sky, a halo exploded, and the spirit energy halo in a radius of 200 was like a mushroom cloud.

This was the most magical scene between heaven and earth. The martial artists of East River City were all admiring the beautiful scene in the sky.
