The Scum Is Related
"This… this…!" Dong Zheng's eyes widened in both shock and disbelief. It was only now did they realized the connection of each thing to another.
Someone wants to protect another, and so they swore an oath of protection to them. This created a magical connection between the two. Then, the magic, or the power of faith from the protected person enters the body of the one who is protecting them, giving them the power to protect them. The sect then used this practice, and their leader, who managed them all, would also receive everyone's power of faith. So, the power of faith that would enter his body is more than the others receive. Yet, it was too late for them to notice that it also put greater strain on their sect leader's body.
