Capítulo 365: The Beginnings Of A Desperate Battle Part Three

Grandpa Mu, eyes widened seeing this sight, his lip quivered as he suddenly shouted out. "The blessing of the Holy One!" 

He had seen this spell once before a long time ago. It was done by the ancestor of their clan during a war between the celestials and the cultivators. It blessed the individuals so that if they were to take an attack that would kill them it would negate it and heal them completely. While at the same time teleporting them out of danger. It only worked once and that person would need to be on the brink of death before it activated. But it would make it so their soldiers could continue to fight without the worry of dying. The technique was so overpowered that even an attack that normally would instantly kill a person would still protect them. But this required a great deal of magic power to accomplish this. He never thought he would get to see such a spell again in his lifetime.
