When making the black Medicinal Pills, Mo Qi had integrated a small root filament from a Five Elements Tree seedling.
He had also used his own Essence Blood as a medium to activate the living factors contained within the root filament.
It was precisely because of these living factors that everyone could sense each other's presence.
What Mo Qi didn't say was that if any of them harbored thoughts of betrayal, these living factors would immediately transform into a deadly poison. It would follow their bloodstream to the heart, seep into their Sea of Consciousness, and then detonate completely.
It wasn't that Mo Qi was cruel and deliberately concealed this, nor was it that he didn't trust them.
Rather, the safety of every single person was at stake.
If even one person turned traitor, without any countermeasures in place, that traitor could use the connection to hunt down all the others one by one.
