When the rest of the red stream reached them, Seth controlled it and expanded it into a bigger cocoon while also enclosing the Chief within.
At the same time, Seth was exited from another side, as he was suffocating from lack of breath but didn't forget to increase the hold to trap the chief monster more.
But the chief might have become somewhat mindless, it was smarter than that, he extricated himself by condensing a ball of light in his hand and then struck the red cocoon. Which instantly vapourised half of it.
And then the monster moved fast and appeared before Seth and struck him in the neck, his nails were sharp and emitted heat without being able to react.
Seth's hand squeezed the two red stones and he poured his aura inside which activated their full power. Out of nowhere, a tsunami flooded the entire street so damn fast without even seth realizing what happened.
Bang!
