Sent to the countryside, I turned the health center into a top-tier hospital.

The fat man glanced at him, then at the skinny man and the baseball cap, and laughed.

That smile was cold, as cold as the winter wind scraping through sheet metal.

"Who the hell do you think you are? Meddling in my business?"

The fat man pulled his hand out of his pocket; it was a folding knife. He unfolded it, and the blade gleamed white in the carriage lights.

Someone screamed in the carriage.

The girl was so frightened that she stepped back and bumped into the seat, her face turning pale.

Cui Ying stood up, wanting to rush over, but her legs went weak, and she held onto the back of the chair, her lips trembling.

Chen Ping looked at the knife but didn't move.

He had seen knives before, in shady casinos, much bigger than this one.

He took a step forward.

The fat man's hand holding the knife trembled slightly.

He didn't expect Chen Ping to be unafraid.

"Don't you fucking come any closer!" The fat man's voice rose, but his confidence was clearly waning.

The skinny man also pulled out a knife from his pocket, longer than the fat man's.

He didn't pull out a knife, but his fist was clenched so tightly that his knuckles cracked.

Three people, two knives.

Chen Ping took another step forward.

The fat man moved first.

He gripped the knife and stabbed at Chen Ping. His movements were quick, but he was untrained and used an amateur technique.

Chen Ping turned to the side, the tip of the knife grazing past his clothes, just an inch away from touching him.

He grabbed the fat man's wrist with his left hand and twisted it outwards. The fat man cried out "Ah!" as his wrist was twisted to an impossible angle, and the knife fell to the ground with a clatter.

Chen Ping punched the fat man in the stomach with his right fist. The fat man groaned, bent over, knelt on the ground, and vomited bile.

The skinny man rushed forward, slashing horizontally with his knife.

Chen Ping leaned back, and the knife swept across his face, creating a gust of wind.

He grabbed the skinny man's arm and pulled him down, then slammed his knee into the skinny man's elbow.

With a snap, it wasn't a broken bone, but a dislocated joint.

The skinny man dropped his knife, hugged his arms, squatted on the ground, his face as white as paper, and beads of sweat rolled down his face.

The man in the baseball cap stood behind, fist raised, but didn't dare come up.

He looked at Chen Ping, then at the two lying on the ground, and turned to run away.

After running a couple of steps, I was stopped by someone.

It was the driver. I don't know when he got out of the driver's seat. He was holding a wrench in his hand and blocking the car door.

"Where do you want to go?" The driver's voice was so loud that the whole carriage was shaking.

The man in the baseball cap paused for a moment, then turned to run back. The men who hadn't dared to move earlier stood up and blocked the aisle.

A tall man clenched his fists, his face flushed red, whether from anger or excitement, it was hard to tell.

Another middle-aged man picked up a fire extinguisher from the ground, held it up, and aimed it at the man in the baseball cap.

"Run! Run!" someone shouted.

The man in the baseball cap squatted on the ground, covering his head with his hands, too afraid to move.

Chen Ping squatted down, took the pink wallet out of the fat man's pocket, and handed it to the girl.

The girl took it, and tears streamed down her face. Clutching the wallet, she cried so hard she couldn't speak.

The driver stood in front of the car door with a wrench in his hand, looked at Chen Ping, smiled, and gave him a thumbs up.

"Bro, you've trained before?"

"I practiced for a few years in college," Chen Ping said with a smile.

The driver nodded, asked no more questions, turned around and returned to the driver's seat, starting the car.

"Master, where is the nearest police station?" Chen Ping asked.

"It's not far ahead, just around the corner."

"Drive over there."

The driver responded and started the car.

The fat man, the thin man, and the man in the baseball cap squatted in the aisle, watched by several male passengers, not daring to move.

The fat man's wrist was swollen, and the thin man's arm was dislocated. Both of them were grimacing in pain, but no one sympathized with them.

Cui Ying stood beside her seat, watching Chen Ping walk back, her legs still trembling. Her eyes were red, her lips were trembling, she wanted to scold him, but couldn't bring herself to say it.

Chen Ping walked up to her and smiled, "It's alright now."

Cui Ying bit her lip, and tears fell down her cheeks.

She clenched her fist and punched him lightly in the chest, twice, then once more.

"You scared me to death." Her voice was trembling.

"I'm really fine," Chen Ping smiled.

Cui Ying lowered her head, wiped away her tears, and remained silent.

She pulled him by the sleeve, dragged him back to his seat, and made him sit down. She then sat down next to him, her hand still gripping his sleeve tightly.

Everyone in the carriage was watching them.

The girl whose wallet had been stolen walked over, her eyes red, and bowed to Chen Ping: "Brother, thank you. If it weren't for you, I would have lost my ID card, and it would have been too much trouble to get a replacement."

Chen Ping waved his hand: "Don't thank me, thank the driver. If it weren't for his sudden braking, everyone would still be asleep."

The girl turned around to thank the driver again. The driver glanced at Chen Ping in the rearview mirror and said, "These three guys are notorious around here. Most cars don't want to mess with them."

"Young man, if you hadn't subdued those three today, I probably would have gotten into trouble the next time I went on my trip."

An old man came over, took out a pack of cigarettes from his pocket, took one out, and handed it to Chen Ping.

He patted Chen Ping on the shoulder, said "Good lad," and gave him a thumbs up.

A middle-aged woman looked at Chen Ping, then at Cui Ying, and smiled: "Young lady, your boyfriend is really something. He's brave, resourceful, and handsome. You've found the right person."

Cui Ying's face flushed instantly, from her neck all the way to the roots of her ears.

She opened her mouth as if to explain, but then didn't. She lowered her head, her lips curling into a wide smile.

Chen Ping didn't explain, just smiled and leaned back in his chair.

The middle-aged woman said a few more things, such as "the couple is a good match" and "they look like lucky people." Cui Ying's face turned redder and redder, but the corners of her mouth turned up higher and higher.

Chen Ping sat beside him, not saying a word, with a slight smile playing on his lips.

The bus turned onto a side road and drove a short distance before stopping in front of the police station.

The driver honked the horn twice, and two police officers came out and asked what was going on.

The driver explained the situation, and the police officers got into the car and took the fat man, the thin man, and the man in the baseball cap off the bus.

The three men had their heads down, each more disheveled than the last. The fat man's wrist was swollen like a steamed bun, the skinny man's arm was hanging limply, and the top of his baseball cap had fallen off, revealing a head of messy hair.

A police officer boarded the bus, took statements, questioned several passengers, and then questioned Chen Ping.

Chen Ping gave his name and ID number, which the police officer noted down. He then saluted and got out of the car.

The doors closed, and the bus resumed its journey.

The atmosphere in the carriage was completely different from before.

Before, I was in a daze; now, it's bustling and lively.

Several people were discussing what had just happened, each one of them talking animatedly.

Some say Chen Ping's punch was brilliant, others say his dodge was even more brilliant, and still others say the driver's sudden braking was the key.

"Young man, what do you do? Have you practiced martial arts?" an old man leaned over from the front row and asked.

"I am a doctor," Chen Ping said.

"A doctor?" The old man paused for a moment, then laughed. "A doctor can fight? He's got both literary and martial skills!"

Everyone laughed.

Cui Ying sat next to Chen Ping, listening to those people praising Chen Ping, and felt particularly proud of herself. She kept smiling and held tightly to Chen Ping's sleeve.

Chen Ping turned his head, glanced at her, and said in a low voice, "Can you loosen your grip now?"

Cui Ying looked down at her hands, which were clenched tightly around Chen Ping's sleeve. She loosened them and smoothed out the wrinkles with her hands, but didn't remove them, leaving them on his arm.

"Don't loosen it." She spoke very softly, so softly that only Chen Ping could hear her.

Chen Ping smiled, said nothing, and turned to look out the window.

Cui Ying's hand remained on his arm, not removed.

Her palms were a little damp, from sweat, but warm.
