Time Travel Starts with the Male Protagonist Working for Me

After traveling through time, Shen An had no system, no cheats, and no plug-ins. He had only one advantage: he had read half the book. He knows who the protagonist is, knows the direction of the plot, and knows the coordinates of each protagonist's opportunity. He didn't seize the opportunity - he couldn't seize it, and he couldn't hold it. He chose an easier path: Before the protagonist gets the opportunity, he first turns the opportunity into a commodity. Before the protagonist meets the heroine, he first establishes cooperation with the heroine. Before the protagonist becomes an immortal, first become his creditor. This is a story about "information gap". It is also a story about "how to turn the protagonist into your own wage earner". Others traveled through time and became the protagonist, while he traveled through time and became a shareholder.
