October 12, 3020, Sunday, Clear.
Hall 3 of Haizhou City Arts Exhibition Center.
All the visitors have been cleared out, and the relevant officials are being questioned.
At this moment, Lu Chuan had already put on his uniform, Shen Yan had also donned a lab coat, a mask, and triple-layer gloves.
The oil painting that was originally hanging on the wall had been taken down.
Laid flat on the ground.
This time, Liu Guodong was taking photos, and Lu Chuan was responsible for extracting fingerprints from the painting and the frame.
After several crime scene investigations, Lu Chuan's ability in fingerprint extraction had clearly surpassed Liu Guodong and others by far.
Extracting fingerprints from the painting was particularly challenging due to the rough and uneven surface of the oil painting compared to the frame.
Shen Yan was assisting Lu Chuan with his work.
