Without the case, Situ Ce helped He Lanbing review the official documents, but he was not familiar with the laws of the Ming Dynasty, especially the way the government office did not understand, so he helped the more he helped.

He Lanbing said several times that he would not do it, but Situ Ce felt that he had nothing to do and was bored to have idle food, so he insisted on helping. He Lanbing had to point to a large cabinet in the corner of the house and said, "You must be really bored. Look, the files of that cabinet are all cases that have not been solved in recent years. Go and see if you can use your magic to break it. That would be a big help."

"Okay!" Situ Ce shouted excitedly, took the key and opened the cabinet. He was stunned when he saw it. There were at least hundreds of books in the cabinet. He turned his head and said, "All these are not broken?"

Helan Bing looked ashamed: "Yes, I don't have the ability, it depends on your ability."

Situ Ce thought that even in modern times where criminal investigation technology is already highly developed, the case-solving rate can reach 30%, let alone in ancient times. He smiled and said, "This cannot be said that, planning is based on people and accomplishing things is based on heaven. God does not open his eyes and refuses to avenge the deceased. No matter how hard we work, we can't do it."

He Lanbing smiled and buried her head in continuing to review the official documents.

Situ Ce picked up a stack and placed it on his copywriting. He decided to study these stacks first to see if he found a case he could handle.

After several times, they all had headless cases where there were only corpses, no other weapons, and no clues of witnesses.

After reading this stack, he moved out another stack. This time, he discovered a case with certain clues, and it can be used to diagnose and investigate clues with investigation value.

The case file shows that the case occurred in a small mountain village called Erdaogou outside the city. It was two years ago. The deceased Hong Dalang was a farmer, his wife Yan, and had two children, both of whom were underage. The murderer was found to be the next door, and he went to his house to borrow rice to cook. He opened the door and found that Hong Dalang was lying on the ground with blood all over his body. He reported to the Dibao and brought people to see it and found that Boss Hong was dead in the house. At that time, his wife Yan and his two children were working in the field. He came and was heartbroken. The Dibao sent someone to report the case to the county government office. The magistrate took Helanbing and others to investigate. After the coroner investigation, the deceased was hit with thirty-two knives, most of which were chested.

The belly, head, neck and other places were fatal. The methods were very cruel. The search site, a blood-covered sharp knife was found under a pot lid on the square table where the house was eating. After inference, it was determined to be a vendetta. However, after investigation, it was found that the deceased Boss Hong was kind-hearted, kind, did not gamble or prostitute, never argued with others, had a good relationship with the villagers, and had never been blushed with others. There were several acres of land in the family and a cow. His wife, Yan, was kind and docile, and the couple was harmonious. Hong Dalang had the strength to do farm work, so his family was rich, had no worries about food and clothing, and did not owe money. So after investigation, he actually had no clues and became a headless case.

The reason why Situ Ce was interested in this case was that he discovered the weapon. If there was a weapon, the fingerprint on it should be extracted, which would be a decisive role in solving the case. However, it is unknown whether the fingerprint on it can be extracted after two years.

Situ Ce took the file and went to Helanbing: "Where is the knife for this case?"

He Lanbing took the file and took a look: "All the murderous weapons, blood clothes and other evidence of the case are in the backyard room. Each case is a bag, written with a number. Just look for it according to the number on the file. Give you the key!"

Helanbing took the key and handed it to Situ Ce. Situ Ce first went back to the house to get the survey box, and then came to the backyard. Sure enough, he saw a separate room with the doors and windows closed. He took the key and opened the lock. When he pushed the door in, he saw several tall shelves neatly lined up in the house. Each shelf was divided into several grids, and there were neatly placed on it. The bags were tied, and a card had a number written on it.

Situ Ce found the bag of Hong Dalang's murder according to the number, took it down, opened it, found a piece of kraft paper and spread it on the ground, and poured everything inside on the paper. There was indeed a sharp knife inside, and a short shirt full of holes, covered with dark black and old blood.

The handle of the knife is a wooden handle with two pieces of wood clamped together. It is very smooth and does not wrap the ropes, which makes Situ Ce breathe a sigh of relief. There are several suspected blood fingerprints on the handle of the knife, which makes him excited. - The murderer stabbed the dead thirty-two swords, and it is very likely that blood stains were stained on his hand, leaving the blood fingerprint on the handle of the knife, which is even more convenient. Just extract the blood fingerprint directly.

He opened the survey box, took out a pair of rubber gloves and tied it on, then carefully clamped the tip of the knife that was generally impossible to leave fingerprints, picked it up, and looked at the bright spot outside the window, and carefully identified whether there were other suspicious marks on it.

Of course, he found nothing.

He put down the knife, took out a mask from the survey box and put it on, took out the pocket digital camera from the survey box, and a ninhydrin sprinkler, took the knife to the outside of the door. He looked at the vague bloody handprints and sprayed it for a while. After a while, several blue and black handprints appeared at the hilt of the knife!

Situ Ce quickly took a bloody handprint with a digital camera. After enlarging it, he observed that the handprint had overlapping friction marks and the fingerprints were painted. Only two of them were relatively clear and could be compared.

He was very happy in his heart, put away his things, returned to the study, and asked He Lanbing: "When the investigation of Hong Dalang in Erdaogou Village, who were you going to the scene?"

"That was a murder case, almost all the constables went there. And me and the magistrate."

"Has anyone touched this knife?"

"I've seen it, well, the constable who came back with the knife should have also touched it. Others should have not touched it. What's wrong?"

"Nothing, I need to extract your fingerprints." Situ Ce took a handprint cartridge and said.

"Oh? What to do?" He Lanbing didn't understand.

"You don't have to worry about it, just print a fingerprint for me. It's time to solve the case."

"Why do you need my fingerprint to solve the case?" Although He Lanbing didn't understand, he still cooperated to dip ink according to Situ Ce's request and printed all the fingerprints of his hands on the paper.

"Okay, thank you!"

Situ Ce took the ink cartridge and went to the Qianya Constables' room. There were only a few constables in the room, including Shi Meng, and the rest went out to patrol the streets. When Shi Meng and other constables saw Situ Ce coming in, they hurriedly stood up and bowed: "Master Situ!"

Yin Yadan and Tang Tang usually do not patrol the streets. They were sitting by the window eating melon seeds. When they saw him coming, they drifted like wind and surrounded him and said, "Master, is there any big case to be solved? Take us with you!"

Situ Ce smiled and said, "I wish there was no case and the world was peaceful, but those thieves would not give us peace."

"Is there really a case?" Tang Tang said, "Then you must bring us two with you and we will follow you to solve the case!"

Yin Yadan also smiled and nodded desperately to agree.
