David immediately uses the blink technique to escape from that place. But those monsters weren't slow. As David is unable to use the full power of his blink technique, those monsters are able to follow him.
But David finally got the chance to counter-attack. Immediately use the sun-ray technique. This time he did not create a single light beam.
Five light beams were created and immediately hit those incoming monsters.
"Boom!!!"
Explosions appear in that place. Naturally, David did not think that was enough to kill those monsters. He can still see those monsters have 60% health. Killing them like this would not be possible.
Because of this, he takes the chance to create more distance. Fortunately, he did that because, at the next second, the previous place where he was standing was destroyed.
