I recommend " The Most Awesome Middleman " and " The Plane Emperor " to you. They are both about cultivation, and they have elements involving businessmen. They are very suitable for your needs. The main character in " The Greatest Middleman " was the middleman Lin Xiaosheng. He did not earn any profit from the price difference. He bought treasures from cultivators and resold them at a high price. His strength gradually grew. The main character of " The World Emperor " started from owning a Chenwei merchant ship and eventually became the Shang Emperor. He built a country with Shang and cultivated Shang. It was very interesting. I hope you like my recommendation.
