Yulei would be lying if she said she felt no fear the moment a gun was pointed at her. Still, Desmond's training and teachings were already carved into her cerebral cortex, and with a calm mind despite her fear, Yulei analyzed her situation.
Two assailants, armed, Yulei did not recognize the exact model of the pistols they were carrying but still managed to deduce that they were caliber 22. The guns showed clear signs of deterioration, and from how the assailants held their weapons, it was probable that they did have no training.
