There was a group of five people keeping watch outside the private room and when Ru came up to them, they immediately stood in her way stopping her from going inside.
Ru rolled her eyes at them and pretended to leave. But her half-turned body moved in a nimble way as she raised her hand and delivered a 'phoenix eye'[1] punch on one of the lackey's temple. Since the punch was precisely at the temple which happens to be the thinnest part of the cranium, the lackey's bulky body fell down; lifelessly.
The others raised their fists to punch her but Ru rolled around a bit and struck with the heal of her hand on another one's forehead making him fall down with a 'thud'. Before others could make sense of her moves, she jabbed her two fingers behind their collarbone and forced them to the ground.
As the group of five men laid unconscious in her feet, she dusted off her hands and said, "Well, this wasn't fun at all."
