With a clanging sound, the chain with the cut lock was removed, and the iron gate was slowly pushed open.
Mr. Zhao, carrying a box, waved his hand behind him.
"Let's get to work, let's first check if there are any signs of use in this area. Doctor Bai, when did this place start being idle, according to your father?"
Fully equipped, Bai Hua approached from behind, covering her mouth with a mask, her voice sounding somewhat muffled.
"In 1991, my father had the archives checked. Haichanglong moved to the Hai Chang Long Building in March 1991, and then this place became idle. Of course, the complete move should have been around June or July of that year. They came here for surveying; they had to call someone specifically to open the door, not even a security guard was left behind."
Mr. Zhao nodded his head, while Mr. Yang, carrying a powerful flashlight, had already walked in.
