December 19th.
Shijima Gorou disappeared, three days after Zheng Haokang hosted a coaching session.
Jiangdong District, Global Elite Fighting Club.
Bang!
Bang bang bang!
Accompanied by rhythmic sounds of punching gloves hitting protective gear.
Two muscular athletes, dressed in red and blue shorts respectively, face off in a sparring exercise on the boxing ring.
The red fighter's punches are fierce and aggressive, pushing forward step by step, his face now flushed red and dripping with sweat.
The blue fighter moves with agility, mainly harassing with jabs, and occasionally counterattacking with a heavy punch, still looking quite relaxed.
"Stop, stop, that's enough!"
Suddenly, the red fighter raised his hand to signal, shouting repeatedly.
Then bending over, hands resting on his knees, gasping heavily:
"Ah Cheng, if you weren't so fit, my last Swing Punch should have knocked you down."
