"Hummm-"
An extremely faint hum, which seemed to act directly upon the depths of the soul, seeped without warning from behind the massive darksteel doors!
Immediately afterward, the temperature in the hall began plummeting at an astonishing rate!
Crack-crackle-
The faint sound of ice crystals forming quietly rose in the air.
Along the edges of the door gap, around the frame, and even across the blue-brick floor near the iron doors, a thin layer of white frost spread at a speed visible to the naked eye.
That white frost radiated an extreme chill, with faint, tiny streaks of icy-blue light flickering within it.
Everyone waiting outside held their breath, staring at the iron doors that had begun releasing an astonishing cold!
Xi Li Rufeng's pupils contracted slightly. "Such powerful icy intent! Has it-begun?!"
In the hall, one could have heard a pin drop.
Before the lingering hum had faded, a surge of bone-piercing cold swept through. What seeped through the gaps in the iron doors was no longer a faint glow, but a fearsome chill.
"Hummm-"
The second hum was clearer, carrying a peculiar rhythm, like the groan of ice slowly growing beneath ten-thousand-year xuan bing.
Crack! Crackle-!
The frost abruptly spread faster, its thin coating turning into icicles.
They grew wildly along the cold darksteel doors, the thick stone pillars, and the smooth blue-brick floor.
The doorframe was instantly covered in thick ice, crystal clear and reflecting the hall's Soul Guidance Lamp light, radiating a terrifying cold capable of freezing Soul Power.
The ice on the floor spread rapidly, unfurling a vast spiderweb of ghostly icy-blue light.
Tiny ice crystals condensed out of thin air and drifted about, every breath carrying a freezing sting that seemed to slice through the lungs and organs.
"Get back!"
