I make a living solving crimes.

The streets of Longcheng are a gorgeous painting that blends Eastern and Western styles, especially in winter, adding a touch of fantasy and romance.

Russian-style buildings stand on both sides of the street. Their round domes and exquisite carvings appear particularly elegant and solemn against the backdrop of the white snow, as if every building is telling the city's long history and unique cultural heritage.

Chang Wei was walking on the sidewalk with the little yellow dog and Long Zu. There was thick snow under their feet, and every step was accompanied by a slight "squeaking" sound, which was the unique melody of winter.

Just after New Year’s Day, the savings bank was filled with old men and women coming to check their deposits.

At counter number one, the old lady handed in the deposit slip and said, "My daughter, please help me check. My death date is approaching."

At counter number two, the old man yelled at the top of his voice: "I can't hear you. Open the door and I'll go in and talk to you."

Behind the iron fence, the savings clerk was shouting at the top of his lungs to deal with all the strange requests from the elderly.

The bank director came out of the office, rubbed his forehead, and patiently advised: "Uncle, Madam, let's go after we finish our business. Don't linger at the counter."

An old lady with a cane came over slowly, nudged the director, and shouted, "Where did you say I could get soybean oil?"

The director swallowed his saliva, leaned close to the old lady's ear and said loudly: "Auntie, I said don't stay."

The old lady stepped back and glared at him fiercely. "I'm not deaf, I can hear you. If you don't give me soybean oil, then give me peanut oil."

When Chang Wei and Li Lai Fu walked in, the scene was in such a mess.

Lai Fu wanted to find the staff to ask about the situation at that time, but was stopped by Chang Wei.

Don't make trouble at this time.

He walked around the savings bank by himself.

The walls had been repainted, but Chang Wei could still see the dark bloodstains that had been hidden and covered up showing through the white lime.

There are many holes on the wooden board on the front of one counter, probably because it was shot at by iron sand at close range and has not been repaired yet.

The iron door leading to the counter is new.

He came out of the savings bank and stood on the street in front of the door. He looked at the surrounding environment, recalled the confessions of passers-by in the files, took out pen and paper and began to draw the process of the robbery.

At 7:45 in the morning, the truck responsible for transporting the cash had just stopped, and two economic police officers carried a metal box into the savings bank to begin the handover.

At this time, four robbers wearing masks rushed in from behind, took out guns and killed two policemen and two savings clerks on the spot. The other staff members were so scared that they hid and escaped.

The robbers went out with the metal box, and the fifth robber came over with a horse. One of the four robbers walked to the truck's cab and beat the driver to death, and then the five of them left on horseback.

As they were leaving, the robbers opened fire because onlookers blocked the road, killing and injuring four people on the spot. They also kicked a five-year-old girl away while galloping on their horses.

The whole process took only three minutes.

Chang Wei drew a sketch and stared at it for a long time. He saw the little yellow dog sniffing and walking back and forth on the street. After thinking for a moment, he called Li Laifu and said, "Go and call the director of the bank to ask him about the exact location where the escort vehicle was parked at that time."

Li Lai Fu spent some time in the savings bank before calling out the director. The two of them walked to the little yellow dog and pointed at the ground.

Chang Wei walked over, looked around, and asked again: "Are you sure?"

"We are at an intersection, and this is the only place where we can park without getting in the way, so the escort vehicles always park here."

"On the day of the crime, too?"

"Yes, I was at the scene when the car was towed away. I could see blood here a while ago... It was the driver's blood. It was a huge pool."

"Do you remember which direction the car was facing?"

The bank director pointed to a direction and asked, "Comrade, Songhua University...haven't the criminals been caught yet?"

Chang Wei was silent for a moment, then said firmly, "We will definitely catch him."

The bank director sighed heavily, "Comrade, you must bring these people to justice. Two of our comrades died in the savings bank. It's too tragic... Xiao Wang's child is only four months old."

Chang Wei nodded, opened the small notebook in his hand, and continued to ask: "Did you see the criminals enter the savings bank?"

"I was in the office. When I heard the gunshots, I lay on the ground against the door frame and took a look. I didn't dare to go out."

"It's right not to go out. Do you remember what kind of gun the criminal had?"

"One of them was holding a homemade rifle, and the others were holding pistols. Oh, and one of them was holding the gun with both hands. He seemed to be a head. The cash boxes were carried by others."

"Did they speak? Can you hear their accent?"

"No, they didn't say a word during the whole process. They just came in and started shooting."

"They didn't come into the office?"

"No, no, they killed the people and left with the boxes."

Chang Wei wrote down everything the director said in a small notebook.

These were similar to the original transcript. He thought for a moment and asked, "Can you help me recall the man with two guns? Are the two guns the same?"

"It's the same. I recognize that gun. It's the one with the big mirror. I played with it before liberation. I can tell it just by the sound."

"Are the two guns the same?" Chang Wei saw that the director didn't understand, so he patiently explained what he meant: "Are the barrels of the two guns the same length?"

"How can I notice that?" The director shook his head. Seeing that Chang Wei did not continue to ask questions, he prepared to walk towards the savings bank with heavy steps. When he reached the door, he turned back and said hesitantly: "Comrade, I'm not sure about the length, but one of the guns seems to have no sight."

Watching Li Lai Fu seeing the director off, Chang Wei squatted in a daze at the spot where the bloodstains were left.

The other members of the Dragon Team returned and stood beside Chang Wei to explain what they had learned.

Although the Municipal Bureau did not cooperate with their work, the basic work at the time of the incident was very comprehensive, and the situation learned by the Dragon Team members was not much different from the transcripts.

"There are two things we need to verify." Chang Wei stood up and saw that everyone in the Dragon Group had taken out their notebooks. He said, "One is why they killed the driver."

He pointed to the direction the criminals rode away on horseback, "This side is opposite to the front of the car. If the criminals wanted to kill the driver, they had to go back a dozen meters."

Zhang Long scratched his head and asked in confusion: "Bloodthirsty?"

Li Laifu shook his head. "They killed the escorting police and the deposit clerk to get the money, but they didn't go into the office separated by a wall and kill people randomly. They didn't talk during the whole process. It shows that they are very organized and have a plan. They won't waste time to kill a driver for no reason."

Chang Wei nodded in agreement and said, "Lai Fu is right. We need to investigate the driver. I suspect that the driver was killed to silence him."

The members of the Dragon Group were immediately excited. No matter what the final result was, at least they now had a new direction for investigation.

Chang Wei turned to look at Fan Tuan'er and Du Ye again, "Go to the Investigation Bureau and check. After the bandit suppression, many people were released after registering on the spot. I want their information."

"You suspect they are bandits?"

"The bank director said that the leader was holding two guns, which is something most people don't have, and the sight of one of the guns was sawed off."

Seeing that everyone didn't understand, Chang Wei patiently explained: "Bandits are not used to using holsters, they all put their guns on their waists. The purpose of sawing off the front sight is to make it easier to draw the gun, so that the front sight will not touch the belt."

"How do you aim?"

"One for close combat and one for long-range shooting, so he has two guns."
