The name Zhao Tie Zhu (lit. Zhao Steel Pillar) sounded pretty unrefined. But, when it came to his nickname, Phantom, it could be said that everyone in the assassin societies around the world know it. Nowadays, the world was too peaceful, and because of that, the assassination business wasn’t going well.
