"Pop, pop...!"
Countless faint bursts rang out.
The Gu Insects filling the air moved with astonishing speed, surging toward the three like a white storm and instantly filling the entire cavern.
Wherever they passed, even the hard rock was gnawed into a mass of tiny pits!
"Buzz!"
Su Wanyue raised her hand, and a Yellow Ring shone on her slender wrist.
Suddenly, it shot out a huge fireball.
With a whoosh, the fireball burst apart, transforming into countless Scarlet Gu Insects.
Under Su Wanyue's control, the Gu Insects resembled scattered sparks.
In an instant, they gathered into a scarlet wall of fire, blocking the onslaught of the countless bone-eroding Gu Insects.

The dark green fluid from their bursting bodies contained terrifying corrosive power.
Even the Scarlet Gu Insects Su Wanyue controlled sizzled when the fluid touched them, their fiery glow rapidly dimming!
"Damn it! Once bone-eroding Gu Insects lock onto a target, they won't stop until one side is dead. There are too many!"
