Buzz!
With the young girl's command given, all those Outer Realm Beings in the hall instantly released countless tendrils, entwining towards the Martial Arts Experts inside the hall!
Whoosh!
The originally dim underground castle began to light up slightly with the appearance of these tendrils!
The crucial point was that those tendrils, like pipes, emitted a faint, cold light, spreading endlessly towards the Martial Arts Experts.
"Ah? What is this?"
The Martial Arts Experts in the hall initially thought they were hidden weapons, instinctively swinging their Battle Sabers to sever those tendrils.
But to their shock, their weapons had no effect on these tendrils... Once severed, the tendrils would immediately begin to regenerate, seemingly possessing an endless Regeneration ability.
In just a few breaths, the glowing tendrils had already stealthily ensnared several Martial Arts Experts, instantly penetrating into their bodies, entering their veins and meridians!
