"Hah!" Hao Zhen flew to the sky and spat out a thunderbolt.
This thunderbolt shrunk into a ball, with the color of lapis lazuli, and charged towards Hao Zhen's opponent with a speed that seemed to be slow but was actually fast.
His opponent was a Gu Immortal of Murong tribe who had a burly stature, with muscles that were like layers of rocks, he had a wide nose bridge, large chin, and small forehead, making his head look like a triangle.
Seeing the thunderbolt approach him, he actually did not dodge and let the thunderbolt land on his body.
Boom.
The thunderbolt exploded, lightning splashed out everywhere, dazzling the spectating immortals' eyes for a moment.
After the lightning dissipated, the Murong tribe Gu Immortal was standing on the same spot without even budging.
There was a patch of burnt color on his chest from which white smoke was still rising.
But, the effect was only that.
