Boom! Boom!
Spiritual Fog gathered above the Heavenly River, and colorful lightning occasionally struck. As the thunderous sound reverberated in the area, it carried with it a horrifying oppression. The boisterous Heavenly River had gradually calmed down, as it seemed to have been oppressed.
Mu Chen looked up at the Spiritual Fog and the colorful lightning that had been compressed by the spiritual energy. They possessed such an amazing power, it would keep a Lower Earthly Sovereign on guard.
Although Mu Chen's body had been refined umpteen times and had become stronger, he still shuddered at the colorful lightning. If he was careless and got hit by the lightning, his body might not be able to take the blow.
