Indeed, this was very strange. The barbarians were chanting an ancient incantation, as if they were worshiping the heavens.
This kind of sacrifice really caused a reaction from the altar in the herb garden.
Were they communicating and preparing to open the barrier through the altar? When many cultivators thought of this, their breathing became heavy, and their eyes were filled with hope.
If they could really open the array, the treasures inside would be enough to make them soar to the sky and allow the forces they belonged to to to advance at least one level.
As the nine old barbarians continued to chant, the altar in the medicine garden lit up and trembled as if it was resonating with something.
Seeing that it was effective, the third Prince's face turned serious. He continued to urge the nine old barbarians to hurry up.
The speed of the old barbarian's incantation increased, and it became louder, carrying an ancient aura.
