Su Nanzhi knew that when the water submerged everything, eight or nine out of ten people in the village wouldn't escape.
She could save people, but she couldn't save that many.
Even though she clearly understood that many of them weren't worth saving.
Su Nanzhi also knew that if the Great Demon before her killed, his thousands of years of cultivation base would be destroyed in an instant.
She looked at him and then at the curtains of water, estimating that the water must have been borrowed from the sea.
This borrowed item also had a cost.
Things existing in nature are inherently innocent, whether they are threatening or not, harmful or beneficial, all these judgments are up to humans.
Su Nanzhi thought for a moment and decided that reasoning was still a more profitable approach, as once the demon turned devil, she might really not be able to defeat him.
