It's what they are now performing, the method of absorbing filth and exchanging it for spiritual energy!
First, they regard themselves as containers, absorbing countless evil filth into their bodies, all while ensuring their survival and consciousness won't succumb or fall.
Just this step alone requires enduring immense torture, and those without extraordinarily strong wills cannot possibly persist.
Then, they use themselves as the Array Eye core to set up an Evil Spirit Reversal Array on the earth.
And this is the most critical and important step in the entire method.
Because this formation, which combines various pathways, was created by Elder Xuan using his extraordinary talent and great wisdom, it can transform evil, filth, and other harmful existences to the world into spiritual energy!
Yet, in the process of setting up the formation, the earth unknowingly got polluted, which is where Elder Xuan and the others are, in Cloud Continent.
