When Feng Tao heard this, he nodded and turned around to leave. He forced himself not to think too much about this matter.

After all, he is very busy now. There have been a lot of things going on in the patrol room recently, which has made him a little overwhelmed.

Cheng Shi followed the procedure and asked Boss Du. Cheng Shi actually didn't have much confidence in this inquiry.

Boss Du insisted that Han Gan's paintings were real, and Cheng Shi did not dare to do anything to him. After all, the other party was considered a respectable figure.

As soon as Cheng Shi saw that he couldn't get anything valuable, he stopped detaining the person and asked Deng Xin to let him go.

Deng Xin looked at Boss Du leaving, looked at Cheng Shi helplessly and said, "Brother Cheng, let's let him go like this?!"

Cheng Shi said with a smile: "Otherwise, what else can we do? If the other party doesn't admit that it is a fake painting, there is no evidence to prove that he is a fraud!"

Deng Xin also understood this truth, so he no longer struggled with this issue, but asked another question in his heart.

"Then what does this fraud case have to do with Tan Jun's disappearance?!"

Cheng Shi thought for a moment after hearing this, and did not answer Deng Xin's question, but led Deng Xin out of the patrol room door.

The two walked out of the door. Cheng Shi looked at the light rain falling in the sky, took a deep breath and said.

"These two things may not necessarily be directly related, but there must be some connection. Before Tan Jun disappeared, he often went there!

Moreover, the painting of Han Gan in this fraud case is one of the paintings of the Tan family, so there must be some connection between the two things!"

After hearing this, Deng Xin also understood why Cheng Shi suspected that the two things were related. He then said, "Then what should we do now?!"

Cheng Shi thought for a moment and said, "Have any news come from the people sent to keep an eye on Tan Jun's personal maid?!"

Deng Xin shook her head and said, "No, they said that the maid's behavior was normal and there was nothing abnormal!"

When Cheng Shi heard this, he smiled and said: "The young master she has been serving has disappeared, and she is doing everything normally. This is not normal in itself!"

Deng Xin glanced at Cheng Shi and said, "Then now I ask them to arrest that maid?!"

Cheng Shi thought for a while and said: "No need for now, just keep an eye on her. If you touch her, you might alert her!"

…

Thirty minutes later, Cheng Shi and Deng Xinlai rushed to Tange's house. Tange heard his servants report that they were visiting and quickly invited them to the living room.

Tang Ge quickly walked up to Cheng Shi and said anxiously: "Agent Cheng, come here now. Have you heard any news about my son?"

Cheng Shi did not speak, but stared at Han Gan's painting in the living room. Tang Ge looked at Cheng Shi without looking back at him, but kept staring at his painting.

Tange immediately understood what the other party meant, and couldn't help but feel anger welling up in his heart, but he still held back his anger.

Tang Ge calmed down a little and said, "Agent Cheng, if you like this painting, I will give it to you!"

When Cheng Shi heard this, he turned around and stared at Tang Ge and said, "Boss Tan, I think you have misunderstood me!"

After hearing this, Tange was stunned and asked doubtfully: "Then what do you mean?!"

Cheng Shi didn't mince words and asked directly: "Is the painting in your living room a fake? I don't know if it is genuine. Where did you put it?!"

Tange's expression became even more ugly as he said, "What does this painting have to do with my son's disappearance?!"

Cheng Shi continued: "Based on some clues, I just found a place where a case of fraud using Han Gan's fake paintings occurred!

The counterfeiting skills of the fake painting are very high. The other party must have come into contact with the original painting, although I don’t know what it has to do with your son’s disappearance!

However, you'd better let me see the authenticity of this painting now. After all, your son's disappearance is very strange, and I have to check for any clues!"

Tang Ge didn't pay attention to Cheng Shi's cold tone, but when he heard that the other party had a clue, he quickly spoke.

"Okay, I get it, I'll take you to see the real thing right now!"

After Tange finished speaking, he led the two of them to a house. There were many people standing guard around the house!

Tang Ge took out the key he carried with him and opened the locks on the three doors. Each lock had a unique style.

When he opened the third room, Tange asked the two of them to wait outside the door. After a long time, Tange let them in.

After Cheng Shi entered, although there were candles burning, it was still a little dark inside. There were many wooden shelves inside, and there were many antiques placed on the wooden shelves!

Then the two of them saw an open secret door behind one of the wooden frames. The secret door looked difficult to open at first glance.

Tang Ge then led the two of them into the darkroom. The darkroom turned out to be bright. Cheng Shi looked at the electric light above his head.

Cheng Shi took another breath of the dry air here, and then looked at the dozen paintings on the wall of the secret room and the rare ancient books on the table.

Only then did Cheng Shi understand why electric lights were used here instead of candles, because there were many flammable items inside.

Cheng Shi walked up to Tang Ge and looked at Han Gan's painting in front of him. He carefully considered the position of the seal.

As he expected, this painting is also fake. Of course, it is also possible that the painting in Tang Ge's hands is fake.

But this possibility was very small. Cheng Shi then looked at the other paintings on the wall. They were all paintings of famous people.

Then he discovered that all the painted seals had the same problem, and it seemed that they were forged by the same person.

Cheng Shi was even more sure of his idea. Tange might have bought a few fakes, but it was impossible that they were all fakes, and they were fakes from the same person. This was simply impossible.

After Cheng Shi read it, he pointed at the flaw and said to Tange: "Boss Tan, these paintings of yours have been swapped. If you don't believe me, look at this part of the seal. These are all written by the same person!"

Tang Ge was shocked after hearing this, and quickly stepped forward to verify each one carefully. After reading it, Tang Ge shook his body and almost collapsed on the ground.

Tang Ge muttered: "How could this happen? How could this happen?!"

Cheng Shi hurriedly stepped forward to support Tang Ge and said, "Boss Tan, who knows about this secret room, and who can come in?!"

Tang Ge took a long time to react and said with an unbelievable look on his face: "There are many people in my family who know this secret room, but I am the only one who can get in. Even my son and my wife don't know how to get in!"

When Cheng Shi heard Tang Ge's words, he smiled and said slowly: "Boss Tan, you are wrong about this. You are not the only one who can come in. I'm afraid the person who helped you create the secret room can also come in!"
