Following the direction of Shen Lian's finger, the blue luminescence was scattered around. Perhaps it was because of how dark the underwater was, and hence the luminescence just looked more noticeable.
When the blue luminescence appeared suddenly, it felt like a blowhole was blowing out air without warning, which caught people unprepared.
It was where the Qi of devilry was extremely thick. As the blue luminescence was born, they scattered around quickly.
The Qi of devilry was wrapped in the light and blended with the sea water. Shen Lian could see clearly that everywhere the blue luminescence went through, the sea water would generate some form of unknown vibration and the deadly feeling followed suit.
