The massive cage and tunnel merged into one, shrouded by a black curtain, with wild beast-like roars echoing incessantly, sending shivers down one's spine.
Archbishop Brandon approached the cage and swung his arm, "Open the door!"
The demon hunter guarding the cage saw that the visitor was Archbishop Brandon, hurriedly lifted the black curtain, took out the keys, and unlocked the colossal door. According to Marvin's observation, this cage seemed to have only one exit, which led to the London Underground. The only way to leave was through this single path.
Creak... Creak...
The heavy iron door slowly opened, and a stench akin to the foul odor of wild beasts rushed forth. Marvin frowned, pulled out a handkerchief to cover his nose and mouth, and followed Archbishop Brandon inside.
