The girl Li Fei saw was none other than Liu Junru, the model who had won second place in the Huaxia Youth Cup.
Liu Junru exclaimed, "Watch out!"
Li Fei thought the samurai were attacking and instinctively turned around. Just at the moment he turned, Liu Junru swiftly and suddenly struck with near-electrical speed, her fingers unleashing nearly ten thousand pounds of force, instantly hitting Li Fei's left and right temples. At this moment, Li Fei was focused entirely on the martial artists and was completely unguarded against Liu Junru, thus he was caught off guard and struck directly.
The temples are the weakest part of the human body; even with the Iron Shield Technique as protection, they're still relatively fragile. Thus, after being struck, Li Fei's world went black, and his body fell backward, unconscious.
