I'm an Assassin in Prison

The Dragon Kingdom has a prison under such tight security that not even a fly can escape. Yet Tang Yin comes and goes as he pleases.

The organization known as S brings together the best scenario planners, hackers, drivers, thieves, lawyers, and assassins.

When the law can't punish a villain, leave it to them.

There is no mission they dare not take, and no one they can't kill.

I'm in a hurry. Once I've killed the villain, I still have to get back to prison.
