The Young Justice Bao: Part Four

The first season of Young Justice Bao was a classic. I especially loved the character Bao Zheng as played by Zhou Jie. It's a shame he didn't appear in the later seasons. I may not be much of a writer, but I can't help wondering: if Conan can stay in elementary school for over a thousand episodes, why can't our classic IP Young Justice Bao do the same? I'm inexperienced with mystery and detective fiction, though, so there will surely be many issues as I write. Please help me polish the story, fellow readers. I'll listen humbly to your thoughts and suggestions, and keep revising and improving it.
