A Hundred Ways to Win Someone's Heart [Quick Transmigration]

This is the story of a scummy bottom carrying a useless System through various worlds, working hard to win over the hearts of his targets in order to obtain their "hearts" (the hearts of the tops). Shen Mo, an acting god, was struck by a System that fell from the sky and was left dead in the street on the spot. To avoid dying for good, he had no choice but to bind himself to the System. Who knew the System would be utterly useless? As soon as they were bound, it announced that its survival energy was running low and that the Host had to replenish it as soon as possible, or the bond would be immediately broken. To recharge it, he had to transmigrate to other worlds and obtain the hearts that the so-called "children of destiny" willingly offered him. Friendly System reminder: The hearts must contain love for the Host as a key, or the energy within them cannot be activated. Shen Mo: "I give you energy. What help can you give me?" System: "...I can provide memories of the characters' pasts and take you to other worlds. That's it." The split-personality top is the same person from beginning to end. This is just a fluffy, uncomplicated story, so please don't take it too seriously n(*≧▽≦*)n. This author is reliable, so feel free to jump in. Theme: Every gift actually comes with a price secretly attached.
