Several people were helping to set up at the Angel Culture and Arts event site, and during their lunch break, they bought some bread to eat, then immediately headed to the Art Heart Auction House.
Although a murder had occurred at the auction house, it was not sealed off.
The police must have finished their investigation and evidence collection.
The group took advantage of the security shift change to sneak into the auction house, and subsequently went to the staff's office where they found the password for the warehouse.
After finding the password, they went straight to the warehouse and opened it.
They began searching the warehouse and found a dropped button. Seeing the style of this button, it was familiar to Nan Chu.
Yesterday, a technician named Luo Chao at the auction house had buttons of this style on his clothes.
Nan Chu could remember so clearly because when entering, this person brushed past her and Hou Pu.
After Hou Pu died, this person came to maintain order.
