In the sun, the deeper the pool, the clearer the shadows are. If you can't see the shadows clearly, it only means that the light is already dim.

Based on experience, the black police officer judged that Yuqu was most likely to want to shelter a certain person. Who did he want to shelter? Who belongs to this iron can? Why did Yuqu’s fingerprints on it?

"Xiao Zhang, I'll go to Youqu's house to inquire about something first."

Before leaving the door, Youqu turned his head and said to his grandfather, "Grandpa, I'm going to surrender, take care of yourself."

Yuqu's grandfather was holding a palm-leaf fan in his hand and was boiling medicine for Yuqu. There were tears in his eyes: "Go, you should listen to the police officer in the detention center."

"I don't know if this folk remedy is useful?" Yu Qu's voice was crying, and it was as small as a mosquito and flies. He pushed open the door and walked out.

Youqu's grandfather stopped his hand, covered his face, and sighed twice: "You go quickly, wait for you to be a new person, grandfather is waiting for you."

Youqu didn't dare to look back, wiped the tears with the back of his dirty hands, and said in a crying voice: "Grandpa, take care of yourself."

He went to the police station and looked around, only to see Officer Zhang: "Officer Zhang, I am from the leader."

"It's good to come." Officer Zhang said, "Take a record with me first. However, after finishing the record today, you can go home."

Youqu looked shocked: "Why? And, where is the black police officer?"

"Oh, officer black, he has something else to do. As for why, maybe it's because your case is more complicated."

The black police officer knocked on the door of Yuqu’s house again, but it was still the door opened by his grandfather.

"Old man, I want to ask a few more things about Euqu."

The old man nodded.

"I heard that Yuqu's mother had just gotten married and was widowed. When Yuqu was three months old, she remarried to a rich man?"

The old man nodded again.

"Have Youqu had any contact with his mother?"

"Every year his mother would take him over to live without her family. He also had a half-brother who went to school at Tianhai No. 1 Middle School."

"It's Tianhai No. 1 Middle School again..." Officer Hei thought.

After inquiring about the address, the police officer Hei went to Yuanshan District to collect clues. Yuanshan District was named after two local richest people. The richest man's surname was Yuan and Shan. The family whose mother remarried to the family was Shan. The villa of the Shan family was built on the hillside of a small hill.

The servant brought the black police officer to the living room.

Officer Black looked at the beautiful woman sitting in front of him. She looked only about thirty years old and didn't look like a woman who already had two children.

"Madam Shan, I'm here this time to inquire about Euqu."

"Xiao Qu? What's wrong with him? Is something wrong?" Mrs. Shan looked obviously nervous.

"Well, whether he is a mistake depends on whether you want to tell us the truth."

"Okay, I'll tell you everything. There is only one requirement. There is no class today. My son Shanping should be sleeping now. Please don't disturb him." Mrs. Shan said calmly.

"Well? Tianhai No. 1 Middle School is the best middle school in the city. As a top student at Tianhai No. 1 Middle School, why is your son still sleeping until eleven o'clock and not studying?" Officer Hei looked suspicious.

"He went out to play with his classmates last night and came back at 1:00 a.m.." Mrs. Shan felt a little embarrassed, but she still answered the questions of the police officer. "That... Tianhai No. 1 Middle School has a system of class division according to grade ranking. He was in the last class and his grades were not very good, so slowly, he relaxed his studies."

"Oh! So that's it." Police Officer Hei paused and asked again, "By the way, you just saw that you were very concerned about Youqu, why didn't you fund him some money and let him treat the disease? Or, improve their family's conditions?"

Mrs. Shan lowered her head: "My husband... controls my living expenses, and reports every in and out of the account truthfully, let alone give me extra money, I have no choice..."

Officer Hei nodded: "Well, I understand, then, Shanping and Youqu, are the two brothers in a good relationship?"

"It's very good." Mrs. Shan rushed to answer, "You know, although Xiaoping is usually rebellious, she is very gentle to his brother."

Officer Black frowned and said as if he was talking to himself: "Sometimes, the more superficial the thing is, the more it is the opposite of the truth."

Mrs. Shan was stunned and couldn't help but pull the corner of the silk fabric.

The black police officer took out an old iron can: "You know this thing."

Mrs. Shan showed a surprised look.

"This is Xiao Qu's thing before. When I saw it was too old, I asked Xiao Ping to take a new one from his room for him. But how could it be in your hands? What happened to Xiao Qu?" Mrs. Shan stood up in a hurry.

The black police officer hurriedly said, "He was falsely accused of murder. This iron can is the thing that framed him. I suspect that this iron can fell into the hands of Shanping. Now, if you want to save your eldest son, you must know the truth from your younger son."

Mrs. Shan covered her mouth with her right hand and tears rolled down one by one: "How could this happen?"

Officer Black glanced at her and stopped talking.

The two came to the room on Shanping.

The black police officer stared at Shanping: "Do you know this iron can? There are not only the fingerprints on it, but also a phenolic substance that we detect with the highest-end instruments. The phenolic substances are usually found in incense, and you also have the smell of incense on your body. It's really a coincidence."

"Haha, yes, it was me who framed Youqu, who asked him to steal my mother, who made things on his face annoying, who made him worse than me. Who made him worse than me, who was not as good as my scum, just to die! I don't want my family property to be taken away, it's all because of that Youqu, it's the best choice to get rid of him." Shanping roared.

Mrs. Shan was so scared that she collapsed on the ground.

"Shanping, don't be excited, put down the knife." Officer Black tried to calm down Shanping's mood.

"No, it's too late! My reputation and future shouldn't be like this now. It should start again. As long as I die, I can find the exit of the underground castle! Everything will start again." Shanping raised his hand and fell, blood splashed out from his neck, slowly falling into a pool of blood.

"Ping!" Mrs. Shan was stunned by the scene in front of her and hurriedly ran over to support Shan Ping, "My Ping! What are you doing? What happened? Why don't you tell your mother?"

The black police officer touched his chest and was sweating coldly.
