I Transmigrated into a Book as an Overpowered Cheat, So What's Wrong with Playing It Safe?

There is a couple, though they don't get much focus. The heroine is a ruthless female boss + transmigrates into a book + System + a battle for supremacy + a max-level powerhouse with amnesia returns to the beginner village. When she was still at the top, she killed whoever she wanted and took whatever she wanted. But after losing most of her strength and means, she became an ordinary person with a great mind but no power to match. She learned how the world worked, then shamelessly exploited the trust and advantages of those around her, all to achieve her goals. Yet more and more people were willing to follow her. The System couldn't understand. “Aren't they afraid you'll manipulate them?” Everyone shouted, “But the boss is willing to coax and trick me! As long as she cares enough to do that, that's all that matters.” The System: “...” It figured Zhao Lan did have one redeeming quality: even if she used you, she paid you for it. At first, she had no moral qualms. She was shameless enough to make everyone hate her, exploiting friendship and trust alike. At first, all she wanted was to finish the mission, collect all the fragments, and leave. But the people following her were too foolish. Even after she tricked them, they still wanted to stay by her side. She had no choice but to make a reluctant bid for the throne. Later, the history books recorded: The founding emperor of the Great Zhou Dynasty. A woman of mercurial temperament, sometimes as cautious as a dog, sometimes as wild as a rabid hare. When provoked, she suffered from a peculiar urge to assassinate her closest friends.
