As for wanting to slam on the brakes to take control?
Hehe, it might be feasible elsewhere, but in the Rakshasa Kingdom, a nation steeped in malevolence, it's absolutely impossible.
Why? Because the profits are too huge.
In his previous life, Yi Chen had observed a clear characteristic of long-standing criminal organizations throughout history—they never touched drugs (wisdom from the Godfather Corleone).
Because human hearts are unpredictable, and desires insatiable, when the profits become too vast, those at the top have no way to control the actions of those below. At that moment, disaster occurs.
This matter, when broken down, might look different on the outside, but at its core it's all the same stuff. Find a few people to form a team, and then you're able to branch out on your own. Yi Chen had already foreseen the scene of the big families in Rakshasa Kingdom cornering the market and shearing the public like sheep, and he, would not give the Rakshasa King a second chance.
