Nether Academy: On the surface it is an ordinary aristocratic academy, but in fact it is a "living barrier" connecting the two realms of Yin and Yang. It opens the "Twelve Earthly Branches Trial" every ten years. The building itself is transformed from a thousand-year-old haunted house. The portraits in the corridor will appear with new faces as the number of deaths increases. The library books record the death records of losers in the past.
