[Qin] I Wanted to Be the Imperial Preceptor, but Became the Crown Prince

Huanling transmigrated to the Warring States period and became a half-demon fox who had been foolish for over a decade. Not long after waking up, her original body's mother patted her on the head and said, "Go find your father." Thinking her father was from Zhao, Huanling quickly headed to Qin. But after accidentally stealing and eating Ying Zheng's lunch, she was "exiled" to the remote mountains by the Imperial Preceptor, Bai Yanliu. From that day on, Huanling plotted to overthrow Bai Yanliu and become the Imperial Preceptor herself. Only by a twist of fate did she discover that her father was actually King of Qin Ying Zheng. And so she embarked on a path of infrastructure development alongside the demons. The little demons with incredible strength went to break rocks and quarry stone. Those with nimble hands and feet transported materials. Those with growing magic researched crop varieties. At the same time, she taught the little demons to read and helped humans develop science. As the people's lives improved, the merit they earned flowed back to Huanling and all the little demons. The demon clans, once on the brink of extinction, had found a new path. As Huanling swished her five fluffy tails and wondered if she could become the Imperial Preceptor, she heard the First Emperor tell his ministers, "I intend to make Prince Huanling Crown Prince. What do you think?" Huanling: Father, just you wait. I'll go research the elixir of immortality right now! An alternate universe, not historical fiction. Theme: Persevere through every setback, and you'll reach the end
