Male antagonist, also known as Boss Zhang or President Zhang, a ruthless leader of a thug group operating in the post-apocalyptic world. He was Yang Ning's former lover and always dealt in shady business. After the apocalypse, he thrived in the chaos, becoming ruthless and untouchable. His glory lasted only two years before his trusted aide Fang Yuan betrayed him. He now controls over forty men and twenty-plus women (former hostesses from his club), using them to scavenge and trade for supplies from his base above the sixth floor of a flooded building.
