'They are all suffering by death aura for some reason,' Alex thought as he looked at everyone that had now landed next to him. The amount of death aura in each person was minuscule in comparison to someone like the Mad immortal who could fuel Godslayer to become a powerhouse for a single attack.
But, the death aura had hidden so deep inside their dantian that normal pills couldn't help them relieve it at all. Every time they cultivated, they would draw from that death aura, passing it along to the rest of their body.
That was why everyone from this sect looked so deathly in the first place. They all were cultivating with death aura without realizing it.
"I'm here under the Emperor's request to check the mysterious deaths. Would you mind taking me inside?" Alex asked.
"Of course," the sect leader quickly said. "You all can return. I will take care of our guest."
The group all flew away, leaving behind only Alex and the sect leader.
