Searching for someone in northern Myanmar, and you call that earning tuition fees?

The old green train swayed and rattled, the carriages filled with the smells of instant noodles and foot odor.

The middle-aged man sitting opposite Su Ming was named Zhang Daqiang. Of course, that was the name on his ID card; only he knew whether it was real or not.

Sweat dripped from Zhang Daqiang's temples as he stared at the "college student" across from him for twenty minutes.

In his view, a boy like Su Ming, who was so handsome he even had a scholarly air, was the best cover. As long as he could act naturally during a police check and stand next to this student, he might be able to get away with it.

"Hey bro, going to Nanyun for a trip?" Zhang Daqiang finally couldn't help but ask, his voice hoarse and tentative.

Su Ming closed the book "Advanced Physics" in his hand, pushed up his black-rimmed glasses, and smiled shyly: "No, I'm going to teach in a rural area."

"Teaching in rural areas is good, teaching in rural areas is good." Zhang Daqiang chuckled dryly, his hands clenching even tighter in his pockets.

Su Ming looked at him with clear, bright eyes and asked in a calm tone, "Brother, if you don't keep that triangular scraper in your pocket safe, the train conductor might prick you when they come to check your tickets later."

The noise in the carriage immediately subsided.

Zhang Daqiang's expression changed drastically, and he suddenly raised the hand that was gripping his pocket.

But before he could draw his knife, Su Ming swiftly reached out with his left hand and precisely grabbed Zhang Daqiang's right hand between his thumb and forefinger.

Before Su Ming could exert any force, Zhang Daqiang felt his entire arm go numb, and half of his body instantly stiffened.

"Don't move." Su Ming lowered his voice, tilting his head slightly, his tone still as if discussing an academic matter. "Your breathing is rapid, and your heart rate is about 120 beats per minute. There are obvious sharp scratches on the lower edge of your jacket pocket, the distinctive mark of a triangular knife. Also, you have a very faint smell of formaldehyde on you. Brother, you escaped from a medical school lab in the north, didn't you?"

Zhang Daqiang looked at Su Ming in horror.

He was indeed a wanted criminal. Three days ago, in order to escape his debts, he broke into a medical school, murdered a lab technician, and stole his belongings. He fled south, thinking he had disguised himself perfectly.

"Who...who exactly are you?" Zhang Daqiang squeezed out a few words through gritted teeth.

"A part-time student earning tuition fees." Su Ming smiled faintly, gently pressing a spot on the other person's neck with his right index finger.

That was the "pressure point method" that his grandfather taught him.

Zhang Daqiang didn't even groan. His eyes rolled back, and he slumped limply into his seat, looking as if he had fallen asleep.

Su Ming casually withdrew his hand, took the knife stained with dried blood from the other person's pocket, wrapped it in newspaper, and put it into his backpack.

He then calmly stood up and grabbed a passing police officer.

"Officer, this man seems to be sick, and... he seems to have a weapon in his pocket."

Five minutes later.

The train conductor and three police officers were all present.

When they found the murder weapon on Zhang Daqiang and compared it with the national wanted poster, they looked at Su Ming as if he were a monster.

"Young man, how did you find out?" The train police captain asked, wiping away cold sweat, as he directed the handcuffing of Zhang Daqiang.

This is a Class A wanted criminal with a murder charge against him!

Su Ming adjusted his glasses, looking both confused and frightened: "I saw he was sweating a lot and thought he had heatstroke, so I wanted to get him some medicine, but I accidentally touched the handle of a knife... It scared me to death."

The police officers exchanged glances, looking at Su Ming's frail appearance, but didn't think much of it. After all, it was already a miracle that an eighteen or nineteen-year-old student could remain so calm in the face of a wanted criminal.

"Good boy, you're very brave! Leave your contact information so we can apply for a 'Good Samaritan' award for you when you get back!"

"A bonus?" Su Ming's eyes lit up. "About how much?"

"Two to five thousand."

Su Ming gave a somewhat disappointed "oh".

Five thousand yuan is a lot, but compared to five hundred thousand, it's still a drop in the ocean.

He sat back down and continued flipping through the book "Advanced Physics." The passengers in the carriage gathered around, praising him as a "heroic young man," and some older women even offered to introduce him to potential partners.

Su Ming responded politely, but in his mind he was calculating the time.

The train will reach the border in four hours.

While his actions just now went smoothly, they also exposed a problem: his physical fitness was still insufficient. Although he had the fighting skills taught by his grandfather, he still had to rely on his wits when facing truly desperate criminals.

He repeatedly mentally rehearsed the terrain of the card area.

Area K covers approximately 3,000 acres and is surrounded by a 3-meter-high wall covered with a high-voltage electric fence. There is a surveillance camera every 50 meters, and patrol teams take turns every hour.

Finding the target girl among thousands of "piglets" is like finding a needle in a haystack.

But he had a last clue about where he was before he disappeared—it was the background noise of a distress audio message.

The audio included sounds of ocean waves, wind chimes, and a rhythmic percussion sound.

The sound of the waves indicates the proximity to a tributary of the Salween River; the sound of the wind chimes is from the distinctive copper bells of the local Pala Temple; and the percussive sound...

That was the roar of a large-diameter drilling rig, which his grandfather had once taught him.

"The factory area under expansion is located on the east side of Zone K, next to a tributary of the Salween River."

Su Ming suddenly opened his eyes, his gaze showing no fear, only calmness.

He took a thin wire out of his bag and deftly wrapped it around his fingertips.

In his hands, this wire could become a lock pick, a cutter, or even... a deadly strangulation cord.

"I hope that girl can hold on until I get through this."

Su Ming muttered to himself.

Outside the car window, the continuous mountain ranges were already faintly visible, and the air began to smell damp and hot.

That taste harbors sin.
