! I'm the Headmaster in Ancient Times!

After finishing a long day at work, Su Xiaoyin had just sat down to catch her breath and eat dinner when she accidentally swallowed a whole egg. It got stuck in her throat, and she choked to death. She then transmigrated into the body of a fourteen-year-old orphan named Su Xiaoyin, who had been dumped by her fiance and lived in a remote village in a fictional dynasty. With her own hard work and modern knowledge, she built a fortune and founded an ancient vocational school, becoming its headmistress.
