The lady in green was being suppressed by the joint efforts of two great Demon Kings and was at a disadvantage, her defeat was only a matter of time, especially as the Heavenly Qi-breaking whirlwind over the sea began to move towards the three of them.

Having spoken, the green-clad woman turned into a streak of green light and flew into the raging Heavenly Qi-breaking whirlwind, instantly swallowed by the storm.
