Everything Is a Tool [Quick Transmigration]

The Shen family has a young master named Shen Tang. He's a beautiful boy, "delicate and sickly," but has a bad temper. Quick transmigration worlds: 1. ABO world. Everyone knows that the young master of the Federation's Clidia family has always had a bad temper, especially toward the Empire's Marshal, Ji Lun Boge. Both are outstanding Alphas, though the young master's reputation for excellence must be counted backward. Delicate and domineering, he's so unreasonable that he's dragged down the standing of the entire Alpha world. Everyone says the Empire's marshal is powerful and cold, and despises spoiled layabouts who never apply themselves. All the more so when the layabout in question belongs to the Federation, the Empire's rival. But the truth is this: before an Imperial-Federation banquet is even over, in a secluded corner, the marshal's eyes are red as he pins the young master against the wall, begging him to be gentle. 2. Spirit world (ancient setting). After death, people become beings called "spirits," which disappear after seven days and enter the cycle of reincarnation. If they fail to enter it, either because they refuse or are prevented, they become "ghosts." Ghosts are often consumed by resentment and need human "spiritual energy" to survive. The greater their resentment, the stronger they become. A thousand years ago, the Eight Great Celestial Master Families finally emerged, and they have maintained order between humans and ghosts ever since. The Shen family stands at the head of the eight. Shen Qingze, the head of the family, is as gentle as jade. He seems kind but is cold at heart. His misty eyes seem to hold all of Jiangnan, and he commands the world of celestial masters while guarding the Shen family's greatest secret: his own crime. He caused his sickly cousin Shen Tang to become a ghost, all for the sake of his own desire. The young master clung to his "cousin's" shoulders and tilted his head. "I'm hungry." Other worlds...
