Bam!
Two figures dressed in dark robes rushed out of the ghost fog and landed outside the Tower of Flames, sending soil, as well as stones, flying in their wake.
The one on the left was more than ten feet tall, with a trident in hand and covered in iron-like muscles, its eyes burning with green flames.
The one on the right, had a pair of dragon horns on its head, with black dragon wings on its back. Yet, it was human-shaped and walked on both feet as it held a bone whip, looking like a fearsome killer.
They were two Ghost Lords that had went through Six Thunder Tribulations and had devoured hundreds of millions of spirits to have their cultivation level as of now.
Among the Ghost tribe of the Ten Infernal Tribes, the Ghost Lord of Six Tribulations was the most powerful existence beneath a Supreme Saint. They had cultivated a solid ghost body and had the same intelligence as a human Saint King.
