"After receiving your call, I examined these blueprints. This was once the secret passage used by Poison Dragon for illegal transactions, now it's an abandoned basement with a door that connects to the city's underground sewers, which I've locked from the inside. The rest of the area is just standard business premises. If Poison Dragon is indeed here, this warehouse is the most likely place. However, to enter, he must pass through the main hall to get to the basement, where security guards are stationed, making it difficult for anyone to come and go."
"If it's Poison Dragon, he must have the key to this door." Once Xiao Lin confirmed the location, he searched for a way to enter and exit here without going through the building. "Since it's the city's underground sewage system, the building should have its drainage pipes. Where is the nearest underground pipe entrance to this area?"
