Let's Go See the Thunder Emperor

Zhong Ao sensed the distinct nomological aura between Heaven and Earth. Not only was he merging his Principal Spirit and physical body, but his cultivation level was also rising. He had even forgotten that he was not upgrading his cultivation level but should be accelerating merging his Principal Spirit and body.

The surrounding dozens of high-grade immortal spirit meridians and the green spirit meridian were slowly used up.

Two huge Essence Energy whirlpools bound Di Jiu and Zhong Ao. Di Jiu's cultivation level improved even faster. Fourth-stage Immortal Supremacy, fifth-stage Immortal Supremacy…

Even Black Fire, who was on the further end, felt his cultivation level rise rapidly at this moment. By the time Di Jiu reached the sixth-stage Immortal Supremacy, it had already gone up to the level-eight immortal demon Thunder Tribulation.
