Hakzuax put everything in place so that Rean could heal batches of 200 cultivators with similar degrees of injuries every time. With that said, he went out and continued to heal more cultivators on his own since it would be meaningless to simply keep looking at Rean. However, he could still feel Rean's presence every time he used that Healing Aura of his.
However, it was then that Hakzuax noticed something. After Rean finished healing a batch, he would stop for a while to recover his Divine Energy. It's just that this time, he was taking way, way longer to restart his healing process than before. Because of that, Hakzuax went back to check on him... just to see that he had left.
Hakzuax looked at one of his subordinates before asking, "Where's Rean?"
The guy immediately answered, "He said that something came up and he had to leave to help his brother. He'll be back in a day or two."
"What?!" Hakzuax was taken aback. "Why the hell didn't you tell me?"
