I, a Max-Level Mage, Place a Strange Copy! ?

What does it mean that I have broken through the tribulation and reached a strange copy! ? After 170 years in Blue Star, Mu Feng finally reached the final state of alchemy. However, after all kinds of torture, what greeted him was not the shocking scene of thousands of rituals but a cold prompt: "Dear Chosen One, you are currently in a D-level copy of the Terror Building. Surviving for 72 hours is considered a successful challenge. I look forward to your triumph." This novel and its characters are purely fictitious.
