Undercover as the Boss, Only to Find the Plot Going Off the Rails?

My name is Chen Mo, and I'm an undercover cop. To take down the biggest gang in the city as quickly as possible, I worked myself to the bone, trying harder than the real gangsters. Then, on his deathbed, the old boss actually passed the reins to me.

My superiors gave me the most outrageous assignment imaginable: stay undercover and keep being the boss!

I'm freaking out inside. I have to keep acting out this gangster drama at an Oscar-winning level until I flush out the real kingpin behind it all.

But it doesn't take long to realize there's something off about this outfit: their smuggling operations always fail, their loan-sharking contracts are legally airtight, and their men specialize in fighting only in self-defense...

What kind of gang is this? It's a legitimate company!

And if this is a legitimate company, then whose operation am I undercover in?
