Of course, it was their secret organization's Poison resistance training, that had greatly helped them this time.
Their training had helped them to survive and become resistant to any poisons at the celestial tier levels and below.
Because of it even if Silver Flower had used up the purple poison, she and Red Root would not be affected at all, making them retain their spirit qi and preserved much of their strength.
And both Happy Kill and Blue Thunder on the other side were seriously harmed and were in the dark. Because they weren't aware of their secret collaboration, they had a faulty image of Red Root instead, making them believe that Red Root was one powerful character who could sustain detrimental techniques and explosions.
Because Happy Kill had used up much of his spirit qi in activating his Misery puppet technique, he was left in a much more bad shape.
