In such circumstances, Reiger used a magic.
"[Refusal of Life Cocoon]."
It was a protective magic that could expel life, forming a barrier through which no creature could pass.
As Reiger chanted this incantation, a radiant shield with a radius of about ten meters arose from the ground, enveloping both Reiger and the group of warriors, safeguarding them.
"Bang!" "Bang!" "Bang!"...
One by one, the vampire bats crashed against the cocoon-like shield, only to be repelled by it, completely unable to penetrate the shield to attack Reiger and the others inside.
"[Impact Wave]."
At that moment, Reiger unleashed a second-tier attribute-less magic, sending out an invisible shockwave like an unseen explosion, which radiated from him and swept across all directions.
"Boom—!"
In the thunderous noise, a multitude of vampire bats were blasted away by the shockwave, scattering showers of dark mist-like blood in mid-air as they were flung backward, falling to the ground.
"Good!"
"Awesome!"
