I Plan for Every Contingency and Become the World's Hegemon

After accidentally transmigrating to the fictional ancient dynasty of Great Yan, Chu Yi becomes a Commissioner of the Guards, a man everyone wants dead. He hopes the System he has just awakened will save his life, but its main trait is sabotaging its Host, and its secondary trait is barely useful. He manages to survive through his own cleverness, but there are always more troublemakers trying to kill him. Luckily, Chu Yi plans for everything, and so begins his rise to power:

The city's richest man? Chu Yi does a little calculating and swindles him out of 150,000 taels. A more thorough calculation leaves him penniless.

Unexpectedly, the princess suddenly appears: "No! I'm going to marry him!"

Just as Chu Yi starts to warm to the idea, the emperor speaks up:

"Please stop calculating! I'm afraid you'll calculate my whole family out of existence. How about this: if you stop, I'll give you the throne?"

Chu Yi: "Sorry, I'm not interested. I'll calculate my way into becoming the world's supreme ruler!"
