Meet Gu Yu—a college dropout and a talented incense maker, and at the same time, the rather stoic protagonist of this story. Despite his somewhat introverted manner, he has a tendency to make sarcastic remarks in his thoughts. One day, after saving a squirrel, a windfall (metaphorically and literally) dropped into his lap. Stumbling into the cultivation world with little help, he was not turned into Superman overnight (as he would like). Apparently, becoming a cultivator would not make your life easier, at least in the beginning.

Somewhere along the road, he ran into Jiang Xiaozhai, a young woman who’s got the brains, the beauty, and maybe one or two secrets of her own. As it turned out, the two made a perfect team—Mulder-and-Scully style. Motivated by many unanswered questions, they had been running up and down the country, getting into all kinds of trouble, and learning more of the modern cultivation world, which is by no means the same as in the ages long past…

I struggled until I was thirty-eight and couldn’t afford a house. I had to pay a gift of three hundred thousand in advance to get married. I lived frugally and frugally for most of my life until my liver was broken. But where was the money? Who made the money?

Jiang Qin, who harbored countless grievances, was reborn at the age of eighteen. The only thought he had when he opened his eyes was to start a business and make money.

The first step is to snatch back the love letter you sent, turn it over, and write three lines in the school belle’s astonished eyes:

You can’t work for anything, and you can stay with a rich woman if you can.

You can make more money if you lose it, but you can make more money if you lose your conscience!

Social animals, never slaves!

As for love? Dogs don’t even talk about that stuff!
