Ever since he transformed Wang Wanqiu into a member of the Demon Race, Lin Yun had almost put the issue of death by drowning behind him.
For one thing, Wang Wanqiu herself had nearly drowned before, right in Dongfang Hongyue's secret base at Holy Spring Lake; had it not been for Lin Yun's kind-hearted rescue, Wang Wanqiu would have been a goner on the spot.
Perhaps that was already considered altering her fate.
Secondly, as long as a cultivator has sufficient Spiritual Energy, breathing isn't necessary, so a cultivator would only drown if they encountered a flood that they couldn't escape from and exhausted all their Spiritual Power in the process.
And now that Wang Wanqiu was a demon, she could live even without a heart, let alone breath.
Therefore, Lin Yun wasn't panicked at all, but he'd overlooked one thing.
Ordinary water is not enough to drown a person, but some special waters are potent enough to do so.
