The middle-aged man led everyone to the second floor, where behind a framed painting in the study was a secret compartment with a combination lock. It was quite a challenge to open without the man's own instructions. Inside the compartment was a small safe embedded in the wall; it required another code and was immobile. Upon opening the safe, Luo Zheng saw high-class jewelry and diamonds, as well as a black ledger. He quickly stepped forward and picked up the ledger.
After browsing through it for a while, Luo Zheng's face turned ashen. He closed the book and handed it to Lan Xue. She looked through it; the ledger contained records of the middle-aged man's bribes, implicating many officials, but the largest amounts involved Song Yan. With this black book, toppling the Song family was impossible, but it was enough to bring down Song Yan. Lan Xue nodded at Luo Zheng and said, "Ghost Hand, take him down and hand him over to the military."
