The three Ice Heart Pearls were enough to show the Changgang Family's sincerity, and also enough to prevent Su Chen from turning on them the moment he got all of the Ice Heart Pearls.
Their thinking was actually very simple.
They wanted to hand over the Ice Heart Pearls in exchange for Su Chen's promise, and obtain Su Chen's protection.
Originally, the Changgang Family had wanted to gather all the Ice Heart Pearls to control the Ice Demon, adding an extra layer of insurance for their hold over Garyu In.
And then go on to dominate the entire Ninja World.
But first of all, back then, one of the nine Ice Heart Pearls had ended up in Yagawa Sazhi's control.
At that moment, the existence of the Ice Heart Pearls could be called crucial, but they weren't truly absolutely indispensable.
So the Changgang Family had gone out of their way to actively search for the other Ice Heart Pearl that had been lost outside.
