I make a living solving crimes.

The sun penetrates the thin clouds with a gentle yet brilliant attitude and slowly falls on the earth.

The sky was a light blue, with a few white clouds floating leisurely, as if they were also enjoying the rare warm winter sun.

The bare branches, against the backdrop of the blue sky and white clouds, outline simple and charming line paintings. Occasionally, a few birds land on the branches, chirping and chatting, adding a bit of vitality to this quiet winter day.

In the quaint courtyard, the two old men looked at the little guy and felt more and more relaxed.

"Grandfather, Grandfather, these are the sweet potatoes that my aunt just baked. They are for you to eat."

Chang Xiaoman's little hands were black. She held the sweet potato high up and stood on tiptoe to bring it to Old Wang's mouth.

Old Wang kept responding, "Hey, hey, the old man doesn't eat it, Xiao Man eats it."

"Grandpa, let's eat together." The little girl stuffed the sweet potato into Old Wang's hand, turned around half a circle, leaned her soft little body against Old Wang's legs, raised her little head and showed a sweet smile.

Old Wang's heart was about to melt. He held Chang Xiaoman in his arms and said softly, "Okay, let's eat together. I'll peel it for you."

"Old ancestor, eat. My uncle said that good children should respect the elderly. Old ancestor, am I a good child?"

"Yes, Xiaoman is a good kid."

"Hehe, the ancestor is the best person in the world."

The little girl was so happy after receiving the praise that she jumped twice on the spot, turned around and opened her arms to hug Old Wang.

On the other side, Chang Long also handed the sweet potato in his hand to Old Man Zhang, "Grandpa Zhang, please eat it. I baked it myself."

Old man Zhang took it hurriedly, "Okay, little Changlong is a sensible and good child."

"Wow wow wow." Chang Long laughed happily, "Grandpa Zhang, who is more sensible, me or my elder brother?"

Old man Zhang held the sweet potato in one hand and gently stroked Chang Long's head with the other hand, saying lovingly: "Little Chang Long is sensible and smart, more sensible than your elder brother."

Chang Long threw a smug look at Chang Wei, "Grandpa Zhang, are you willing to teach me your skills?"

"What skills do you want to learn?"

"Teach me sign language, my brother just taught the policewoman, it's fun."

"Grandpa Zhang doesn't know sign language." Old Man Zhang saw the disappointment in Chang Long's eyes and said quickly, "But Grandpa Zhang knows hand seals. Do you want to learn?"

"Handprints? Are they powerful?"

"Very powerful." Old man Zhang put down the sweet potato in his hand, formed a seal with his hands, and said, "All those who are about to fight will march forward in formation."

Although it was just nine simple words, Chang Long's heart trembled, and he shouted quickly, "This is amazing, I want to learn it, I want to learn it."

Old man Zhang smiled and said, "Okay, Grandpa Zhang will teach you, and only you, not your elder brother."

"Yeah, Grandpa Zhang is so nice... Grandpa Zhang, I'll bring your tuition over tomorrow."

"Wow, little Chang Long still has money?"

"I, I don't have any money. My money was thrown into the pot and my mother took it away... But I can steal the bacon from our home and give it to you. My eldest brother said that bacon was used as tuition fees in the past."

Old man Zhang smiled and said, "Grandpa Zhang doesn't want your tuition. Whatever you want to learn, Grandpa Zhang will teach you. He will teach you all the skills in his body."

"Okay, I want to learn. When I grow up, I want to be better than my big brother."

"Yes, you have to be more promising than your elder brother."

Chang Wei ignored the two "rebels", patted his butt, stood up, and slowly walked back to the central courtyard.

The sun was shining brightly at this time, and everyone from the Dragon Group walked out of the office and chatted in the yard to bask in the sun.

Chang Wei walked over and passed out cigarettes, then asked with concern, "Laifu, how are you doing in school recently?"

"It's OK. My foundation is weak. I can only do more exercises."

"What did you learn?"

"Learning linear equations in two variables."

Wu Jimao scratched his head and interrupted, "Two yuan per time? What kind of equation is so expensive? Is your monthly salary enough?"

Two yuan was almost enough for him to buy a box of Colorful Vanishing Cream!

Fan Tuaner glanced at him and said, "Stop chatting with Zhang Long. Your brain is broken."

Zhang Long opened his mouth, lowered his head and dared not refute.

Wu Jimao knew he had said the wrong thing, he just smiled foolishly and didn't argue.

He really doesn't know about linear equations in two variables.

When he was in junior high school, he was busy planting rice, harvesting rice and cutting grass for pigs all day long. He fished for three days and dried the nets for two days at school. He had no time to study.

Chang Wei ignored his nonsense and continued, "It's enough to understand the quadratic equation. You can also study geometry if you have time. It's more practical. After New Year's Day, organize the knowledge of footprint identification and write an article. I will submit it to the department for you."

"Okay, I'll review it for you after I finish writing it."

"Well, practice your calligraphy more when you have nothing to do. When you write on the blackboard in class, don't write like chicken paw prints."

Li Laifu was confused. Why were there both classes and writing on the blackboard?

What do you mean?

Fan Tuan'er smiled and said, "You don't understand what Chang Wei means? He said that you write the article and he will help you submit it to the department."

"Uh... not appropriate. I learned everything from Chang Wei."

"He's already the deputy director, how can he have time to care about these things? You should study hard, he has many other skills."

"Chang Wei..."

Chang Wei casually waved his hand to interrupt him and said to Wu Jimao: "You and Jiang Hongxia go to the art school tomorrow and look for Lan Xiaojie."

"Okay, is it about the execution?"

"Well, it will be carried out the day after tomorrow. Ask her if she wants to see it."

"Okay, oh, isn't it a bit too cruel to let such a delicate little girl watch the execution?"

"Delicate? She's not that fragile. She dared to wait for Zhang Yu alone at night for revenge. If we didn't take action, can you guess how she would take revenge in the end?"

Wu Jimao thought for a while, nodded and said, "Okay, I'll go tomorrow morning."

Chang Wei reminded him again, "Take Jiang Hongxia with you. Don't be stupid enough to go into such a colorful place alone."

Wu Jimao sneered, "I won't make such a mistake."

Chang Wei didn't say anything more.

He doesn't have many friends, Lai Fu and Jimao are two of them.

Lai Fu lost his father in his childhood and was the eldest in the family. He had a calm personality and was a man of few words. When he was in the police station, everyone liked this hardworking man.

But in fact he doesn't have many friends. Most people order him around but they don't necessarily respect him sincerely.

Wu Jimao was in a similar situation. Since he came from a suburban county and was frugal, he was often excluded. During his more than three years in the police station, he did the hardest and most tiring work.

Stupidity is just his protective color.

But the two of them are kind-hearted, just and responsible. When Chang Wei first arrived at the police station, the two of them stood by Chang Wei.

Especially the time when they were blocked while catching a thief. The two men blocked their retreat. One had his arm swollen and the other had his head broken, but they never took a single step back.

This is also the reason why Chang Wei always brings them with him.
