So after translating the code, Morse code, the password is butterfly. This brings us to an old painting with chine text. When I googled it I got “The former Zhuang Zhoumeng is Hu Die, and Hu Die is vivid, self-evident. I don't know Zhou Ye.
Suddenly, I felt thin and thin. I don’t know that Zhou’s dream is Hu Dieyu, and Hu Die’s dream is Zhou You. Zhou and Hu Die must be divided. This is called materialization.”
If you click the text you get “¿butterflydream.jpg¿Once, Zhuang Zhou dreamed he was a butterfly, a butterfly flitting and fluttering about, happy with himself and doing as he pleased. He didn't know that he was Zhuang Zhou.¿Suddenly he woke up and there he was, solid and unmistakable Zhuang Zhou. But he didn't know if he was Zhuang Zhou who had dreamt he was a butterfly, or a butterfly dreaming that he was Zhuang Zhou.”
not sure if this will be like Clue or Rocky Horror. Both have Tim Curry. But does this poem reflect this story or does it reflect Jack himself? Or both?
